Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of Invention] (Industrial Application Field) This invention has a front support and a rear support for securing support rigidity, respectively, attached to the front region and the rear region of a foldable hood. Hood structure for a fixed hood type sunroof device.

(Prior Art) There is a hood-type sunroof device called a so-called canvas top in which a hood is provided in a roof opening of a vehicle body, and the hood is folded and moved in the front-rear direction of the vehicle body to open and close the roof opening.

The foldable flexible hood used for the canvas top has a bag portion formed by folding back the edge portions on the back side of the front support member and the rear support member that secure the supporting rigidity in the front region and the rear region. Then, the front end side is fixedly supported on the back surface of each support body, and in the intermediate region, the front ends of the slide top and the floating top bone extending in the vehicle width direction are folded back to the back surface of the edge portion. It is supported by being inserted into the insertion hole. The slide hood and the floating hood are paired and arranged adjacent to each other, and when opened, the hood is folded by floating the hood.

By the way, since the roof of the vehicle body, particularly the corner portion thereof, is usually spherical, the corner portion on the upper surface of the canvas top is also spherical.

Therefore, for example, when a hood structure in which the entire circumference of a rectangular hood member is folded back is formed, wrinkles occur on the surface of the corner portion, and the appearance quality deteriorates. Therefore, as shown in FIG. 4 cited from Japanese Utility Model Laid-Open No. 63-11229, a structure in which an end edge and a side edge portion of a hood 3 supported by a front support (rear support) 1 are slightly folded back, One end of a separately prepared hood member 5 is heat-welded at the joint portion 7 to the lower portion of the folded-back portion 3a and the other end side is bonded to the back surface of the front support body (rear support body) 1. Since the tension is a separate member, wrinkles on the surface of the hood at the corners are prevented from occurring.

(Problems to be solved by the invention) By the way, when inserting each of the front and rear supports into the bag part of the hood, grasp the back side of each support of the hood, and the hood surface has good appearance quality. For this reason, it is desirable that the tension is strong when fully closed, so that the structure requires a considerable amount of force during insertion work. Therefore, if the back side portion of the hood has a structure in which it is joined (heat-sealed) to the front side portion, this joint portion may peel off during insertion. Even if the hood does not come off during insertion, the hood is pulled in the front-rear direction when fully closed, so that the tension at this time acts on the joint, and it easily comes off.

Therefore, an object of the present invention is to provide a hood structure of a hood type sunroof device in which a joining portion between a front side portion and a back side portion of the hood in the front area and the rear area of the hood is not peeled off.

[Structure of the Invention] (Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a foldable hood in the roof opening, and a front part that secures the supporting rigidity of the front part and the rear part of the hood. The hood is supported by the support and the rear support, respectively, and the hood covers the front side of each support, and the edge of the cover is slightly folded back to the back side of each support and one end is joined to the folded part. A backing having the other end fixed to the back surface of each support, and a bag portion into which each support is inserted is formed by these upholstery and backing and folded back to the back surface side of each support. The joint between the surface covering and the lining is extended to a length that can be grasped with fingers, and the extended portion is fixed to the back surface of each support.

(Operation) When inserting the front support and the rear support into the bag portions of the front area and the rear area of the hood, it is possible to grasp the extended portion that is folded back to the back side of the hood, so that the insertion work is performed. The insertion force in (1) acts only on the surface covering, not on the joint between the surface covering and the lining, so that the joint does not peel off.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 shows a foldable flexible hood 11 used for a canvas top. The hood 11 has its front region supported by a strip-shaped front support 13 which is long in the vehicle width direction, and its rear region supported by a strip-shaped rear support 15 which is also long in the vehicle width direction. Although not shown, the middle area of the hood 11 is formed in a portion 17 in which the tip portions of the sliding hood bone and the floating hood bone that are extended in the vehicle width direction are folded back to the back surface side of the hood 11. It is supported by being inserted into the insertion hole 19. The front and rear edges 17a and 17b of the folded-back portion 17 are located near the rear end of the front support 13 and the front end of the rear support 15.

When the hood 11 is fully closed, the hood 11 has a spherical shape as a whole along the roof shape of the vehicle body, and particularly the front support 13 and the rear support 15
Since the upper surface C of the corner portion is located in the vicinity of the corner of the vehicle body roof, its curvature is large.

As shown in FIG. 1, the hood 11 includes a cover 21 that covers the surfaces of the front support 13 and the rear support 15, and a backing 25 that is joined to the cover 21 at the joint 23 by heat welding. . The outer cover 21 and the backing 25 form a bag portion 26 into which the front support 13 is inserted. A front end side of the upholstery 21 is folded back at a folding back portion 21a, and an extension portion 21b thereof is bonded to a back surface of the front support body 13. The length of the extension portion 21b from the joint portion 23 to the tip may be such that it can be grasped with a finger.

The end of the lining 25 on the joint portion 23 side is edge-folded toward the folded-back portion 21a, and the edge-folded portion 25a is joined to the lower portion of the folded-back portion 21a by heat welding. An end portion of the lining 25 opposite to the joint portion 23 is further extended from the extension portion 21b of the upholstery 21 and adhered to the back surface of the front support 13. Note that the front support
At the tip of 13 is a protective material made of rubber or the like to prevent the top 11 from being damaged.
27 is inserted.

FIG. 2 is a sectional view taken along the line II-II of FIG. 3, and the rear hood structure is the same as the front hood structure shown in FIG.
Further, the hood structure on both side edges of the front support 13 and the rear support 15 in the vehicle width direction is similar to the hood front end and the rear end shown in FIGS. 1 and 2.

In this way, the front edge, the side edge and the rear edge of the front support 13 and the rear support 15, and the folded back portion of the upholstery 21 at the side edge to the back side can be grasped with fingers. Since only the relatively short extension 21b is formed, the surface of the surface covering 21,
In particular, wrinkles are less likely to occur at the portions in contact with the front and rear surfaces of the support bodies 13 and 15 having the spherical shape near the vehicle body roof corner portion.

To attach the front support 13 and the rear support 15 to the hood 11, the front support 13 and the rear support 15 are placed in the bag portion 26 while the extension 21b folded back to the backside of the cover 21 is grasped with fingers. Insert each tip of. Since the pushing force at the time of this insertion work acts only on the outer surface 21 and does not act on the joint 23 between the outer surface 21 and the backing 25, the joint 23 does not peel off.

Further, when the canvas top is fully closed, the hood 11 is pulled in the front-rear direction, but the tension at this time does not act on the joint portion 23, but only on the outer cover 21, so that the joint portion is peeled off. There is no such thing.

[Effects of the Invention] As described above, according to the present invention, the extension portion is extended from the joining portion of the lining to the folding portion of the covering to a length that allows the covering to be grasped with fingers. Since the front support and the rear support are fixed to the back surfaces, the tension in the front-rear direction of the hood does not act on the joint but only on the outer cover, so that the joint does not peel off.
