Description

  The present invention relates to a tonneau cover device for a vehicle that can cover or open an upper part of a cargo compartment in conjunction with an opening / closing operation of a hatchback door of the vehicle.

  In recent years, in a tonneau cover device provided in a hatchback type vehicle, one end of a tonneau cover seat is attached to a hatchback door, and the other end is wound around a seat winder provided with a winding mechanism disposed near the rear of the rear seat. It has a structure. A tonneau cover sheet having a required length can be pulled out and taken up from the sheet take-up portion by opening and closing the hatch back door.

  Usually, in this type of vehicle, the distance between the rear pillar garnishes facing each other is gradually narrower than the width of the cargo compartment from the bottom to the top of the vehicle. Therefore, when the hatchback door is opened, the rear pillar garnish and the tonneau cover seat In order to effectively avoid interference, notch portions for avoiding interference are formed on both side portions of the tonneau cover sheet facing the rear pillar garnish.

  However, when the notch portions are formed on both side portions of the tonneau cover sheet, the narrowest portion is formed at the position where the notch portion is formed, and the shape becomes wider from the narrow position toward the drawing direction of the tonneau cover sheet. For this reason, there is a risk that the both side edges of the expanded region that becomes wider in the pulling-out direction of the tonneau cover sheet may sag.

  Since such a spread area portion has a narrow width on the sheet winding portion side and widens in the pull-out direction, in the state where the above-described sag occurs, the vehicle width direction in the sag portions on both sides The narrower one is closer to the seat winder side, and the wider one in the vehicle width direction is located farther from the seat winder. Therefore, when the tonneau cover sheet is wound around the sheet winding portion in a state where such a sag occurs, there is a possibility that the sag portion may be wound in a folded state, and the winding operation may not be performed smoothly. There is.

  In addition, when the tonneau cover sheet is wound in a folded state, the tonneau cover sheet may be folded, resulting in a poor appearance and a problem in durability.

  In particular, in a vehicle equipped with a curtain bag, an inflator for deploying the bag is provided in the rear pillar garnish. Therefore, in recent years, the rear pillar garnish is large, and the notch is also formed large in the vehicle width direction and the vehicle front-rear direction. Further, the sagging of the tonneau cover sheet becomes larger, and there is a possibility that the winding operation cannot be performed.

  In view of the above problems, an object of the present invention is to provide a tonneau cover device for a vehicle that effectively prevents drooping of a tonneau cover sheet that may be caught in a folded state.

  In the movable support 68 and the internal moving body 64, the slider main body 63 reaches the rearmost position of the vehicle 10 in the rail main body 32 by the restriction piece 34 a provided on the rear side of the vehicle 10 in the rail main body 32. The position is regulated so as to come into contact with and stop at the regulating piece 34a before. That is, when the slider portion 60 moves along the rail portion 30 in the direction of the vehicle 10, the position of the movable support portion 68 and the internal moving body 64 is restricted by the restriction piece 34 a, and then the slider body portion 63 is further moved rearward of the vehicle 10. It can be moved.

  The slider drive mechanism unit 40 includes a transmission unit 42 and a spiral spring 50 as a power storage biasing member.

  The transmission part 42 is configured to be able to move the slider part 60 forward of the vehicle in response to the opening operation of the hatch back door 14. More specifically, the transmission portion 42 includes a first winding drum portion 43, a second winding drum portion 44, and a second wire 45.

  The first and second drum sections 43 and 44 are coaxially connected to each other so as to be integrally rotatable, and can be rotated through the reel section housing housing 46 at the intermediate portion in the longitudinal direction of the rail section 30. It is supported.

  The first winding body 43 is formed in a substantially disc shape and is configured to be able to wind the first wire 54. Here, the first wire 54 is a linear member that can be wound, and one end thereof is connected to the hatchback door 14. When the hatchback door 14 is opened, one end portion of the first wire 54 is pulled toward the outside of the opening of the luggage compartment 12, and when the hatchback door 14 is closed, an excessive length is generated in the first wire 54. . Further, the other end portion of the first wire 54 is connected to the first winding drum portion 43, and the excessive length portion of the first wire 54 generated by closing the hatch back door 14 can be rewound onto the first winding drum portion 43. It is configured. In addition, the 1st wire 54 is arrange | positioned through the inside of the rear pillar garnish 13c which is a part of the side wall part 13 of the luggage compartment 12 here.

  The second winding drum portion 44 is configured to be rotatable in conjunction with the first winding drum portion 43. Here, the first winding drum portion 43 is configured to be integrally rotatable with the second winding drum portion 44 by being integrally connected to the second winding drum portion 44 in a coaxial manner. It may be configured such that it can be separately rotated and can be linked and rotated via a gear, an endless annular belt, or the like.

  Here, two second wires 45 are used, and are wound around pulley bodies 48 that are rotatably supported at both ends of the rail portion 30. Further, one end portion of each second wire 45 passes around the side of the rail body portion 32 and is wound around the second winding body portion 44 at the middle portion in the longitudinal direction, and each other end portion is wound on the rail body portion 32. They are connected and fixed to the pair of support end portions 63b of the slider portion 60 through the inside. Then, the second wire 45 moves so as to rotate around the rail portion 30 in conjunction with the rotation of the second winding drum portion 44, and moves along the rail portion 30 so as to pull the slider portion 60 accordingly. Let Such a configuration can also be realized by using a single wire as the second wire 45.

  Further, the spiral spring 50 receives the opening operation of the hatch back door 14, the first wire 54 is pulled out from the first winding body 43, and the first winding body 43 rotates, so that the first winding body part is rotated. 43 is configured to store an urging force in a direction in which the first wire 54 is wound and in a direction in which the slider portion 60 is urged rearward of the rail portion 30. Here, the inner peripheral end portion of the spiral spring 50 is fixed to the central shaft portion of the first winding drum portion 43, and the outer peripheral end portion of the spiral spring 50 is fixed to the winding drum portion housing housing 46. Then, when the first winding body 43 rotates so that the first wire 54 is pulled out, the slider spring 60 is moved upward in front of the vehicle 10 in conjunction with this, and the spiral spring 50 is elastically deformed so that the diameter thereof is reduced. Then, the rotational force in the opposite direction, that is, the urging force for moving the slider portion 60 downward and rearward of the vehicle is stored. When the hatchback door 14 is closed, the urging force stored in the spiral spring 50 is released, the first winding body 43 is rotated in the opposite direction, and the first wire 54 is wound. In conjunction with this, the second winding drum portion 44 is rotated in the same direction to move the slider portion 60 rearward and downward of the vehicle 10.

  In addition, when the slider part 60 moves back along the rail part 30, the weight of the slider part 60 itself, the weight of the tonneau board part 70, etc. applied to the slider part 60 act on the slider part 60. For this reason, the urging force by the spiral spring 50 is set to an urging force that allows the tonneau board portion 70 to be deployed in consideration of those loads. Considering these loads, the biasing force required for the spiral spring 50 does not need to be so large.

  Further, the spiral spring 50 is attached so that the diameter of the spiral spring 50 is reduced even in a closed state where the hatchback door 14 is closed, that is, a state where the slider portion 60 moves to the lower rear end portion of the vehicle and the tonneau board portion 70 is deployed in a flush manner. The first winding body 43 is biased in the direction in which the first wire 54 is wound, and the second winding body 44 is moved in the direction in which the slider portion 60 is moved toward the rear of the rail portion 30. Is energized.

  One end portion of the first wire 54 is connected and fixed to the hatchback door 14 via a wire fixing portion 55.

  The wire fixing portion 55 includes an elongated housing 55a, a wire end fixing tool 55c, and a coil spring 55e as an urging member, and is hatched back via a door side fixing tool 55b fixedly attached to the hatch back door 14. It is connected and fixed to the door 14 (see FIGS. 17 and 21).

  The wire end fixing tool 55c is configured such that a head portion having a diameter larger than that of the rod-shaped portion is provided at one end portion of the rod-shaped portion, and one end portion of the first wire 54 is connected and fixed to the other end portion. A coil spring 55e is fitted over the rod-shaped portion of the wire end fixture 55c. Further, the housing 55a is formed in a hollow bowl shape, and a wire end fixing tool 55c is movable therein, and a coil spring 55e is extendable. When the first wire 54 is pulled, the coil spring 55e is contracted, and the first wire 54 is pulled out from the wire fixing portion 55 by the contracted amount. Further, when the force for pulling the first wire 54 is released, the coil spring 55e is extended, and the first wire 54 is pulled back into the wire fixing portion 55 by the extension. A door-side fixture 55b is attached and fixed in advance to the hatchback door 14, and the housing 55a of the wire fixing portion 55 is detachably connected and fixed to the door-side fixture 55b.

  When the hatch back door 14 is opened, the slider portion 60 stops at the front end portion of the rail portion 30 and the drawing of the first wire 54 from the first winding drum portion 43 is stopped. Thus, a slight amount of the first wire 54 can be pulled out.

  Here, at the upper and lower limits of the design opening / closing range of the hatch back door 14, the coil spring 55e is appropriately lengthened and contracted so that the wire end fixing tool 55c is positioned at the approximate center of the movement range in the housing 55a. It is good to set it like this. As a result, when the actual opening / closing range of the hatchback door 14 is larger than the designed opening / closing range (for example, when + 5 ° is larger), the coil spring 55e is contracted and the first wire 54 is pulled out, so Can be supplemented. On the other hand, when the actual opening / closing range of the hatchback door 14 is smaller than the designed opening / closing range (for example, −5 ° smaller), the coil spring 55e is extended, and the first wire 54 is drawn and loosened. Can be eliminated. In this case, the surplus length of the first wire 54 generated when the hatch back door 14 is closed may be preferentially pulled back by the wire fixing portion 55, or may be given priority by the first winding drum portion 43. You may make it wind up. Which is preferentially functioned can be appropriately set by the biasing force of the coil spring 55e and the spiral spring 50.

<Overall operation>
The overall operation of the tonneau cover device 20 configured as described above will be described.

  FIG. 21 is a perspective view showing a state in which the hatchback door 14 is rotated 30 ° around the hinge portion from the closed position and opened, FIG. 22 is a side view showing the same state, and FIG. 23 is a diagram showing the hatchback door 14 closed. FIG. 24 is a side view showing the same state when rotated 60 ° around the hinge portion from the closed position, FIG. 24 is a side view showing the same state, and FIG. 25 is 90 around the hinge portion from the position where the hatchback door 14 is closed. FIG. 26 is a perspective view showing an open state that is completely opened after rotating by .degree., And FIG. 26 is a side view showing the same state.

  First, in the closed state in which the hatchback door 14 is closed, as shown in FIGS. 1 to 4 and 21, the slider part 60 is at the lower end rear end position of the rail part 30, and the tonneau board part 70 and the tonneau cover part 77 are unfolded. Thus, the upper part of the cargo compartment 12 is completely covered. Further, the first wire 54 is wound around the first winding body 43. Further, even in this initial state, the slider body 63 of the slider portion 60 is urged to the rear side of the rail portion 30 against the urging force of the coil spring 65 by the initial urging force of the spiral spring 50, and the internal movement The body 64 is located at a substantially intermediate portion between the pair of support end portions 63b (see FIG. 18). In this initial state, the slider portion 60 is urged backward. Due to this urging force and the urging force of the tonneau cover portion 77 in the winding direction, rattling of the slider portion 60, the tonneau board portion 70 and the tonneau cover portion 77 is suppressed.

  In this state, when the hatchback door 14 is opened by a user operation or the like, as shown in FIGS. 21 and 22, the first wire 54 is pulled out from the first winding body 43, and the first wire 54 is pulled along with the drawing. The 1st drum part 43 and the 2nd drum part 44 rotate. As a result, the second wire 45 rotates around the pair of pulley bodies 48, and the slider portion 60 moves along the rail portion 30 in the upward direction on the front side of the vehicle 10. As a result, the slider portion 60 and the rear end portion of the tonneau board portion 70 connected and supported by the slider portion 60 and the sheet winding portion 79 of the tonneau cover portion 77 move upward while moving upward from the initial position. Then, the tonneau board portion 70 is bent at the bent portion 74 between the rear plate-like portions 72b, 72c, 72d. At this time, since the rear end portion of the tonneau board portion 70 is moved upward while being lifted upward, the rear portion of the tonneau board portion 70 is smoothly and relatively disposed with a relatively small force on the front portion. The tonneau board portion 70 can be bent. Further, the second cover portion 78 b of the sheet member 78 of the tonneau cover portion 77 is gradually pulled out from the sheet winding portion 79.

  Further, when the hatch back door 14 is largely opened, as shown in FIGS. 23 and 24, the first wire 54 is further pulled out, and the slider portion 60 moves further along the rail portion 30 to the front side of the vehicle 10. To do. Accordingly, the rear end portion of the tonneau board portion 70 and the sheet winding portion 79 of the tonneau cover portion 77 are moved upward while being further lifted upward. Then, the tonneau board part 70 is further bent at the bent part 74 between the rear plate-like parts 72b, 72c, 72d, and is folded into a substantially Z-shape. Further, the second cover portion 78 b of the tonneau cover portion 77 is further pulled out from the sheet winding portion 79.

  As shown in FIGS. 21 to 24, in the state where the slider portion 60 has moved to the intermediate portion in the longitudinal direction of the rail portion 30, as shown in FIG. 19, the movable support portion 68 and the internal moving body 64 by the restricting piece 34a. Since the position restriction is released, the internal moving body 64 is biased to the rear support end 63b side by the biasing force of the coil spring 65.

  When the hatchback door 14 is fully opened, as shown in FIGS. 25 and 26, the first wire 54 is further drawn out, the slider portion 60 moves along the rail portion 30, and the rail portion The vehicle 30 moves to the front end position of the vehicle 10. Accordingly, the rear end portion of the tonneau board portion 70 and the sheet winding portion 79 of the tonneau cover portion 77 are moved upward while being further lifted upward. Then, from the above state, the tonneau board part 70 is also bent at the bent part 74 between the front plate-like part 72a and the rear plate-like part 72b, and the tonneau board part 70 has its rear part on its front part. The upper part of the luggage compartment 12, particularly the upper rear part, is opened in a folded manner. Further, the second cover part 78 b of the tonneau cover part 77 is further pulled out from the sheet winding part 79.

  As a result, the user can access the luggage compartment 12 from above and behind the luggage compartment 12 and load / unload the luggage into / from the cargo compartment 12.

  In this state, the rear end portion of the tonneau board portion 70 only rises to the upper end portions of the pair of rail portions 30. Since the tonneau board portion 70 is bent at a plurality of locations, the uppermost end portion thereof is sufficiently lower than the conventional case where the tonneau board is folded in half. Therefore, a sufficient space can be provided between the rear end portion, which is the uppermost end portion of the tonneau board portion 70, and the ceiling surface of the luggage compartment 12. Therefore, if the front end portion of the seat member 78 is removed from the hatchback door 14, the package is delivered between the rear seat and the opening of the cargo compartment 12 using the space between the tonneau board portion 70 and the ceiling surface of the cargo compartment 12. Can be easily performed.

  In addition, when the slider portion 60 reaches the forefront position of the rail portion 30 and stops before the hatchback door 14 is completely opened as described above due to manufacturing or assembly errors, The first wire 54 is slightly pulled out from the wire fixing portion 55. Thereby, even from the state where the slider portion 60 is positioned at the forefront position of the rail portion 30, the hatchback door 14 can be further opened to be in a completely opened state. That is, the length dimension of the first wire 54 in a state where the slider portion 60 is stopped at the foremost position of the rail portion 30, and the length dimension of the first wire 54 required in a state where the hatch back door 14 is fully opened. The error can be absorbed when and do not match.

  When the hatch back door 14 is closed from the opened state of the hatch back door 14 and the hatch back door 14 is closed, the urging force stored in the spiral spring 50 is released, and the urging force of the spiral spring 50 releases the first winding drum. The part 43 and the second winding body part 44 rotate. Then, the first wire 54 is wound by the rotation of the first winding body 43. Further, by the rotation of the second winding body portion 44, the second wire 45 moves around the pair of pulley bodies 48 in a circular manner, and the slider portion 60 moves along the rail portion 30 downward in the rear of the vehicle 10. Thereby, the rear end portion of the slider portion 60 and the tonneau board portion 70 connected and supported by the slider portion 60 and the sheet winding portion 79 of the tonneau cover portion 77 move downward while moving downward. When the slider portion 60 reaches the lower end position of the rear end of the rail portion 30, the tonneau board portion 70 expands in a flush manner, and the second cover portion 78 b of the sheet member 78 is taken up in the sheet take-up portion 79. Then, the first cover portion 78a and the tonneau board portion 70 return to the state where the upper portion of the cargo compartment 12 is covered.

  In this state, due to the initial biasing force of the spiral spring 50, the slider body 63 of the slider portion 60 returns to the state of being biased to the rear side of the rail portion 30 against the biasing force of the coil spring 65. That is, in the slider portion 60, the movable support portion 68 and the internal moving body 64 are restricted by the restricting piece 34 a and stopped before the position of the rear end portion of the rail portion 30. It is possible to further move the vehicle 10 rearward by the urging force and rotate the first and second winding drums 43 and 44. Thereby, the first wire 54 can be further wound in a state where the hatch back door 14 is closed and the movable support portion 68 and the internal moving body 64 of the slider portion 60 are stopped. Accordingly, the length dimension of the first wire 54 in a state where the movable support portion 68 and the internal moving body 64 are stopped at the rear position, and the length of the first wire 54 that is appropriate when the hatchback door 14 is completely closed. If the dimensions do not match, the error can be absorbed.

  According to the tonneau cover apparatus 20 configured as described above, when the hatch back door 14 is opened, the first wire 54 is pulled out from the slider drive mechanism 40 along with the opening operation, and the slider 60 is connected to the rail 30. It moves upward along the rail portion 30 from the lower end toward the front of the vehicle 10. Thereby, the rear end part of the tonneau board part 70 and the front end part of the tonneau cover part 77 move forward and upward, and the upper part of the luggage compartment 12 is opened.

  Further, since the hatch back door 14 is pivoted upward to be opened, the seat member 78 moves while being pulled out of the sheet take-up portion 79 with the opening operation of the hatch back door 14. At this time, the interval between the opposed rear pillar garnishes 13c at the rear of the cargo compartment 12 is gradually narrowed upward, but a cutout portion 78c is formed facing the rear pillar garnish 13c in the second cover portion 78b that is pulled out. This prevents mutual interference during operation.

  In the opened state of the hatch back door 14, the first cover portion 78a and the second cover portion 78b are pulled out from the sheet take-up portion 79, and the narrowest width in the second cover portion 78b. In the widened area S that becomes wider from the narrow position toward the drawing direction of the sheet member 78, a sag part 100 as shown in FIG. 10 is generated on both side parts (outside the imaginary line position in FIG. 7). Although there is a fear, the rod-shaped core member 91 can effectively prevent the both side portions from hanging downward.

  Note that, as shown in FIG. 7, even in the widened region T that becomes wider from the narrow position toward the winding direction of the sheet member 78, there are hanging portions on both side portions (outer portions from the imaginary line position). Although it may occur, when the sheet is wound by the winding core 79a (see FIG. 9) of the sheet winding portion 79, the sheet is gradually wound from the wide position side in the spread region portion T, so that a drooping portion is generated. However, since the drooping portion is wound while being returned to the original flat state as it is wound, no trouble occurs.

  When the hatchback door 14 is closed from this open state, the spiral spring 50 of the slider drive mechanism 40 moves the slider 60 to the rear of the vehicle 10 to deploy the tonneau board 70 in a flush manner, and tonneau cover. The upper portion of the luggage compartment 12 can be covered in the initial state where the second cover portion 78b of the portion 77 is wound up.

  When winding up the sheet member 78 of the tonneau cover 77 during the closing operation of the hatch back door 14, the occurrence of the hanging portion 100 in the spreading region portion S is effectively prevented by the shape retaining action of the rod-shaped core 91. When the second cover portion 78b is wound into the sheet winding portion 79, there is no winding in a folded state, and the winding operation is smoothly performed. Accordingly, it is possible to cope with the cutout portion 78c regardless of the shape and size thereof, and there is an advantage that the sheet member 78 is not creased, the appearance is improved, and the durability is excellent.

  In addition, a rod-shaped core 91 as a sag-preventing means is provided at a portion of the sheet member 78 where the first cover portion 78a and the second cover portion 78b are sewn, and the first cover portion 78a and the second cover portion 78b are provided. The rod-shaped core material 91 can be attached simultaneously with the sewing, and there is an advantage that the assembling work is easy and the working time can be shortened.

  Further, the sheet winding portion 79 in the tonneau cover portion 77 is moved upward in the vehicle 10 in conjunction with the opening operation of the hatch back door 14 and is moved in the downward direction in the vehicle 10 in conjunction with the closing operation of the hatch back door 14. With the hatch back door 14 in the open state, the seat take-up portion 79 is in a position moved upward, so that the tonneau cover portion 77 can be greatly opened upward, and the inside of the cargo compartment 12 for the user. This is advantageous in that it is easy to check and loading and unloading work becomes easier.

<Modification>
FIG. 27 shows the second embodiment, and is an explanatory diagram of a core 79 a portion in the sheet winding unit 79. That is, a plurality of rod-shaped cores 91 as a drooping prevention means provided in the second cover portion 78b of the sheet member 78 in the tonneau cover portion 77 are separated in the extending region portion S in the drawing direction of the sheet member 78 (this embodiment). 2), and when the second cover portion 78b is wound around the core 79a of the sheet winding portion 79, each rod-shaped core 91 is moved from the center of the core 79a in the radial direction. Thus, the structure is arranged at a position where they do not overlap each other. Other structures are the same as those in the first embodiment.

  Therefore, in the present embodiment, the same effect as described above can be obtained, and the plurality of rod-shaped core members 91 can more reliably prevent the sagging in the spread region portion S. Further, it is possible to effectively prevent the winding diameter when the sheet member 78 is wound around the sheet winding portion 79 from being increased, and to achieve a compact size.

  In addition, in each said embodiment, although the structure provided not only with the tonneau cover part 77 but the tonneau board part 70 was shown, the structure without the tonneau board part 70 may be sufficient. At this time, the present embodiment shows a structure in which the sheet winding portion 79 of the tonneau cover portion 77 is moved in the vertical direction in conjunction with the opening / closing operation of the hatch back door 14. A structure that is detachably attached to the side may be used.

  Further, the structure using the rod-shaped core member 91 is shown as means for preventing the sagging, but the shape retaining structure can prevent the sagging without causing any trouble in the winding and pulling operation of the sheet member 78 by the sheet winding unit 79. I just need it.
