Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a locking device for a rear seat of a vehicle.

In order to store long objects that cannot fit inside the trunk, the seat back of the rear seat is made foldable, and the long objects can be stored between the space above the seat back that is folded down onto the seat cushion and inside the trunk. A rear seat for a vehicle constructed as described above is well known in the art. In such a folding rear seat, when the seat bag is in the upright use position, the seat bag can be locked by a locking device to prevent the seat bag from inadvertently falling over. However, this locking device can be unlocked from inside the car, so if you lend your car to someone else, the locking device may be unlocked without your permission and your belongings in the trunk may be tampered with or stolen. There is a fear.
The above-mentioned inconvenience is an important problem that cannot be ignored, especially considering that there are many occasions in recent years when people have to hand over their cars to complete strangers.

The present invention has been made based on the above recognition,
It is an object of the present invention to provide a lock device that can disable unlocking if necessary.

Advantageous embodiments of the invention will be described below with reference to the drawings.

FIG. 1 shows a foldable rear seat 2 of a passenger car 1,
1 is a schematic diagram showing the arrangement of a locking device 3 according to the invention; FIG. The rear seat 2 has a seat cushion 4.
and a seat back 5, and a trunk room is located behind the seat back 5. 1a is a trunk lid that opens and closes the upper opening of the trunk room. The seat bag 5 is supported so as to be tiltable between an upright use position shown by a solid line in FIG. 1 and a reclined position shown by a chain line. When the seat bag 5 is in the use position, the seat bag is locked by the locking device 3 to prevent the seat bag from inadvertently falling forward. In addition, "before" and "after" as used in this specification
means the front-rear direction of the vehicle (the left-right direction in FIG. 1).

The details of the locking device 3 will be explained with reference to FIGS. 2 to 4. Both flanges 8 of a substantially U-shaped support bracket 7 are fixed to the lower surface of a package tray 6 provided behind the seat bag 5. A pivot shaft 10 is fixed. A hook member 12 having a hook 11 at its front portion and a handle member 14 having a grip 13 at its upper portion are rotatably supported on this pivot shaft 10. On the other hand, at the upper part of the back of the seat bag 5, there is a hanging member 1 formed in a substantially U-shape, as shown in FIG.
5 is secured, and this latch member 15 engages the hook 11 of the hook member 12 when the seat bag 5 is locked, as shown in FIGS. 2 and 3. The grip 13 of the handle member 14 projects above the tray 6 through a notch 16 formed in the package tray 6, and is adapted to be operated from inside the vehicle. That is, the handle member 14 is provided at a position where it can be rotated from inside the vehicle. On the other hand, the hook member 12 is entirely disposed in the trunk below the package tray 6, and is provided in a position that cannot be rotated from inside the vehicle. Reference numeral 17 denotes a tension spring which is locked at each end to the handle member 14 and the support bracket 7, and this spring 17 gives the handle member 14 a clockwise rotational habit in FIG.
Moreover, the back surface of the handle member 14 abuts against the end surface 18 defining the notch 16 of the package tray 6, thereby holding the handle member 14 in the state shown in FIG. On the other hand, the hook member 12
3 and biased in the clockwise direction in FIG. It is prevented from rotating clockwise beyond the position shown in FIG.

Reference numeral 21 denotes an unlocking inhibiting means that disables unlocking of the locking device as necessary, as will be explained in detail later.In this example, the unlocking inhibiting means 21 is
It has an actuating lever 24 which is pivotally connected to a bent portion 22 formed by bending the bottom plate 19 of the support bracket 7 by a pivot pin 23, and a connecting member 25 which connects this lever 24 and the handle member 14. are doing. The actuating lever 24 and the connecting member 25 are arranged in the trunk below the package tray 6, and the unlocking inhibiting means 21 can only be operated from outside the vehicle with the trunk lid 1a for the trunk compartment open, as will be described later. . Connecting member 2
As clearly shown in FIG. 4, the numeral 5 consists of a round bar-shaped pin 26 extending laterally, and a projecting pin 28 integrally formed with the pin 26 via a support rod 27. Each end of the pin 26 is slidably fitted into an elongated hole 29 formed in the rear part of the handle member 14, while the projecting pin 28 is inserted into the operating lever 29.
It is rotatably fitted into a hole 30 formed in 4. In this case, in the state shown in FIG. 3, the pin 26 of the connecting member 25 is in contact with the front end 31 of the elongated hole 29 (see also FIG. It is in contact with the contact portion 32. Therefore, the handle member 14 and the hook member 12 are connected to each other by the pin 26,
These members 14 and 12 can rotate together on the pivot 10. 33 is the operating lever 2
4 and the bent portion 22. This spring 33 has a so-called toggle function, and the actuating lever 24 can be moved to the first position shown in FIGS. 3 and 5. 6 and 7, or the second position shown in FIGS. 6 and 7. 34 and 35 move the operating lever 24 to the first position.
and a stopper for stopping at the second position, these stops 34, 35 being attached to the support bracket 7. Further, a link 3 is provided at the end of the operating lever opposite to the side where the hole 30 is formed.
One end of the link 36 is pivotally connected, and this link 36 extends rearward along the inner surface of the side wall in the trunk compartment, as shown in FIG. 1, and the rear end is rotatably supported on the vehicle body by a support pin 37. It is pivotally connected to the actuating member 38 (FIG. 3). This actuating member 38 is located in the trunk.

The lock device 3 is generally constructed as described above, and when the seat bag 5 is in the operating position shown in FIGS.
and the locking member 15 engage with each other, and the other elements of the locking device 3 also maintain the state shown in FIG. 3, so the seat back 5 is firmly locked and its forward tilting is reliably prevented. be done.

When tilting the seat back 5 forward, grasp the grip 13 of the handle member 14 from inside the vehicle and pull it forward, thereby moving the handle member 14 counterclockwise in FIG. 3 against the action of the spring 17. rotate in the direction. At this time, the actuating lever 24 maintains the first position shown in FIG. maintain the condition. Therefore, when the handle member 14 is rotated counterclockwise, the hook member 12 is also rotated counterclockwise against the action of the spring 20, as shown in FIG. is disengaged from the latch member 15. The seat back 5 is thus unlocked and can be freely tilted forward. When the grip 13 is released, the handle member 14 and the hook member 12 are released by the springs 17, 2.
0 automatically returns to the position shown in FIG.

When the seat bag 5 is raised to return to its use position, the hook member 15 hits the outer surface of the hook 11 and acts as a cam surface, so that the hook member 12 rotates slightly counterclockwise together with the handle member 14. Afterwards, the latch member 15 engages with the hook 11, and the seat bag 5 is locked again.

Next, a description will be given of the operation when the above-mentioned seat bag cannot be unlocked, such as when handing over the car to another person. In this case, keep the seat back 5 locked as shown in Fig. 3, open the trunk lid 1a (Fig. 1), and operate the actuating member 38 provided at the rear inside the trunk from outside the vehicle. Rotate this clockwise in FIG. 3 and push the link 36 forward in the figure. As a result, the actuating lever 24 is moved to the pivot pin 2.
3 in the clockwise direction and reaches the second position shown in FIG. is maintained. When the operating lever 24 rotates as described above, the connecting member 25 also operates, and the pin 26 moves toward the rear end 31a of the elongated hole 29, thereby causing the pin 26 to come into contact with the hook member 12. It comes off from section 32. Therefore, the integral connection state between the hook member 12 and the handle member 14 is released, and even if the handle member 14 is rotated counterclockwise in FIG. 6 by gripping the grip 13, the handle member 14 will not rotate. Although the hook member 12 moves, the hook member 12 remains engaged with the latching member 15 and does not rotate (FIG. 7). This prevents the locking device from being unlocked and makes it impossible to fold down the seat back 5 from inside the vehicle, so as long as the trunk lid 1a is closed and locked, the luggage in the trunk can be stolen or tampered with. This can definitely be prevented. still,
Handle member 14 rotated to the position shown in FIG.
is prevented from rotating counterclockwise beyond this position by a stopper (not shown).

When the actuating member 38 is rotated counterclockwise to return the actuating lever 24 to the first position and the pin 26 of the connecting member 25 is engaged with the abutting portion 32 of the hook member 12, the locking device is activated in the first position. Return to the state shown in Figure 3.

8 to 13 show a second embodiment of the present invention, in which the unlocking inhibiting means 2
1 has an actuation lever 24, but does not have the connecting member of the previous embodiment, and therefore does not have an elongated hole in the handle member. Moreover, this operating lever 24 is rotatably supported on the handle member 14 by a pivot pin 23, and a protrusion 40 bent at the tip of the operating lever 24 is attached to the hook member 12.
It is designed so that it can come into contact with an abutting portion 32 formed in the. Further, the actuating lever 24 in this example is also in the first position (10th position) where the protrusion 40 touches the contact portion 32
11) and a second position (FIGS. 12 and 13) in which the protrusion 40 is removed from the contact portion 32. In this case, the torsion coil spring 33 with a toggle function, which holds the actuating lever 24 in these positions,
One end thereof is latched to the actuation lever 24, and the other end is latched to the handle member 14 itself. Further, stoppers 34 and 35 for stopping the operating lever 24 at the first position and the second position are located on the handle member 14.
It is installed protrudingly.

The other configurations of the second embodiment are substantially the same as those of the first embodiment described above, and the parts similar to those of the previous embodiment shown in FIGS. 8 to 13 include:
The same reference numerals as those in FIGS. 2 to 7 are given, and detailed explanation thereof will be omitted. Further, its operation is almost the same as in the previous embodiment. That is, when the hook 11 and the hook member 15 are engaged with each other and the seat bag 5 is in a locked state as shown in FIG. At this point, the handle member 14 and the hook member 12 are integrally connected. Therefore, the handle member 14 is inserted into the tenth position from inside the vehicle.
When the seat bag 5 is rotated counterclockwise in the figure, the hook member 12 also rotates accordingly, the hook 11 is disengaged from the locking member, and the seat bag 5 is unlocked (FIG. 11).

To inhibit unlocking of the locking device, open the trunk lid (see Figure 1) and close the actuating member 38.
is operated from outside the vehicle to rotate the operating lever 24 clockwise and disengage the protrusion 40 from the contact portion 32 of the hook member 12 (FIG. 12). Even if the hook member 12 is rotated as shown in FIG. 13, the hook member 12 remains engaged with the latching member 15 and does not rotate, so that the locking state of the locking device is maintained. As in the previous embodiment, the handle member 14 that has been rotated to the position shown in FIG. 13 is prevented from being rotated counterclockwise beyond this position by a stopper (not shown).

By the way, as is often seen in recent vehicles,
When the seat back of the rear seat is divided into two parts and the two divided seat backs are configured to be able to tilt independently, each of the divided seat backs can be provided with the above-mentioned locking device. However, in this case, the unlocking prohibition means of each locking device must be operated separately.
The operation becomes somewhat complicated, and it is inevitable that it will be inconvenient to use. The embodiments shown in FIGS. 14 to 20 are constructed to eliminate this inconvenience, and the details thereof will be explained below.

The rear seat 2 shown in FIG. 14 also has a seat cushion 4 and seat backs 5, 5a, and a trunk room is located behind it, but the seat back in this example is divided into two parts (in this specification, the seat back is divided into two parts). When it is necessary to distinguish between the seat bags 5 and 5, one seat bag 5 will be referred to as a first seat bag and the other seat bag 5a will be referred to as a second seat bag.) These first and second seat bags 5, 5a are supported so as to be able to tilt independently between a use position shown by a solid line in FIG. 14 and a reclined position shown by a chain line. These first and second seat bags 5,
When the seat bag 5a is in its use position, it is locked by the first locking means 103 and the second locking means 103a provided for each seat bag, so that the seat bags 5, 5a do not accidentally fall forward. It is designed to avoid any inconvenience. In this way, the locking device 3 in this example is
and second locking means 103, 103a, each of which has a structure similar to that of the locking device 3 shown in FIGS. 1 to 7 except that the actuating member 38 is removed. Moreover, the first locking means 103 and the second locking means 103a
are constructed in the same manner as shown in FIG. 15, and the respective means 103, 103a are spaced apart from each other in the lateral direction of the vehicle. Therefore, the first locking means 10 corresponding to each element of the locking device shown in FIGS.
3 are given the same reference numerals as those given in FIGS. 1 to 7, and the first locking means 10
Each element of the second locking means 103a corresponding to each element of the first locking means 3 will be distinguished by adding the numeral "a" to each element of the first locking means 3. When it is necessary to specifically identify each element of the first and second locking means, the word "first" is used for the element of the first locking means 3, and the word "second" is used for the element of the second locking means 3a. distinguish them by adding The structure of the first locking means 103 will be described in detail below, focusing on the differences from the locking device shown in FIGS. 1 to 4.

As can be seen from FIGS. 15 and 16, the unlocking inhibiting means 21 in this example is pivotally mounted to the bottom plate 19 of the support bracket 7 by a pivot pin 23 so that it can rotate within a substantially horizontal plane. operated lever 24
and a connecting member 25 that connects this lever 24 and the handle member 14. This connecting member 25 is also formed almost similarly to the connecting member 25 shown in FIG. 4, and as shown in FIG.
Each end of the protrusion pin 28 is fitted into a long hole 29 of the handle member 14, and the projecting pin 28 is rotatably fitted into a hole 30 formed in a rising portion 139 of the operating lever 24. The operating lever 24 and the connecting member 25 in this example are also arranged in the trunk below the package tray 6, so that the unlocking inhibiting means 21 is not operated from inside the vehicle.

FIG. 16 corresponds to FIG. 3 explained earlier, similarly FIG. 18 corresponds to FIG. 5, FIG. 19 corresponds to FIG. 6,
FIG. 20 is a diagram corresponding to FIG. 7,
When the actuating lever 24 is in the first position shown in FIGS. 16 and 18 and shown in solid lines in FIG. When the actuating lever 24 is in the second position shown in FIGS. 19 and 20 and shown in phantom in FIG.
6 is engaged and disengaged from the contact portion 32 as in the previous embodiment. Further, a torsion coil spring 33 that biases the actuating lever 24 to either the first position or the second position is locked at each end by the bottom plate 19 of the support bracket 7 and the actuating lever 24, and is actuated. Stoppers 34 and 35 for stopping the lever 24 at the first or second position are also provided in a protruding manner on the bottom plate 19. Also in this example, a link 36 is pivotally connected to the actuation lever 24, and this link 36 and the actuation lever 24
A snap 22 is interposed between the two members 36 and 4, thereby reducing the frictional resistance between the two members 36 and 24.

Another configuration of the first locking means 103 is that the locking device 3 shown in FIGS.
The structure is exactly the same as that except for the hook member 12.
The handle member 14 is provided in a position that cannot be rotated from inside the vehicle, and the handle member 14 is provided in a position that can be rotated from inside the vehicle. Also, as explained earlier, the second locking means 103
a has the same structure as the first locking means 103, and therefore a detailed explanation regarding the structure of the second locking means 103a will be omitted.

Now, the first link 36 and the second link 36 in the first and second locking means constructed as described above.
The rear end of a is pivotally connected to an actuating member 38 via snaps 40, 40a similar to the snap 22 described above. The actuating member 38 in this example is formed into a lever shape, and is attached to a support pin 42 on a bracket 41 fixed to the package tray 6 via a mounting plate 39.
It is pivotably mounted for rotation in a substantially horizontal direction. and the first and second links 36, 36a.
are pivotally attached to each end of the actuating member 38 with the supporting pin 42 interposed therebetween, and one tip of the actuating member 38 is configured as a grip 43. In this way, the actuating member 38 is provided at a position where it can be rotated only from outside the vehicle with the trunk lid open.

The operation of locking the seat bags 5, 5a in their use positions or releasing the lock is performed by the first locking means 103 and the second locking means 103a.
Although they are carried out separately, the mode of operation is the same for both, and the mode is the same as in the embodiment described above. Therefore, the lock release operation in the first locking means 103 will be briefly explained.

As shown in FIG. 16, when the hook 11 and the locking member 15 are engaged with each other and the seat bag 5 is locked, the operating lever 24 is in the first position, and the pin 26 of the connecting member 25 is in the hook position. At the contact portion 32 of the member 12, the handle member 14 and the hook member 12 are integrally connected. Therefore, if the handle member 14 is rotated counterclockwise in FIG. 16 from inside the vehicle, the hook member 12 will also rotate integrally, the hook 11 will be disengaged from the locking member 15, and the seat bag 5 will be unlocked. (18th
condition). Handle member 14 and hook member 12
When the connecting member 25 rotates, the connecting member 25 rotates around the axis of the protruding pin 28, and the pin 26 remains in contact with the abutting portion 32.

When attempting to disable the locking device, the first and second seat backs 5, 5a should be kept locked, and the trunk lid (first
), open the grip 4 of the actuating member 38 from outside the vehicle.
3 and rotate the actuating member 38 counterclockwise in FIG. This allows the first link 3
6 is pulled rearward (in the direction of arrow A), the first operating lever 24 rotates around the first pivot pin 23 in the counterclockwise direction in FIG. When the actuating lever 24 reaches the second position, the actuating lever 24 is held in the second position by the cooperative action of the torsion coil spring 33 and the stopper 35, as in the previous embodiment. When the operating lever 24 is rotated to the second position as described above, the connecting member 25 is also pulled to the position shown in FIG. 19 accordingly. That is, the pin 26 moves in the direction of the rear end 45 of the elongated hole 29, so that the pin 26 touches the abutting portion 32 of the hook member 12.
come off from Therefore, the integral connection state between the hook member 12 and the handle member 14 is released.

On the other hand, by rotating the actuating member 38 as described above, the second
The link 36a is pushed forward (in the direction of arrow B) as shown in FIG. Therefore, the second actuating lever 24a rotates counterclockwise around the second pivot pin 23a, and reaches the second position shown by the chain line. Thus, just as in the case of the first locking means 103,
The second pin 26a of the second connecting member 25a is removed from the second contact portion of the second hook member 12a, and the connection between the second hook member 12a and the second handle member 14a is released.

When the first and second locking means 103, 103a are in the above-mentioned state, the first or second grip 1

4, 14a in the counterclockwise direction in FIG. 19, the first or second hook member 12, 12a
Since the connection between the handle member 14 and the first or second handle member 14, 14a is released, as in the previous embodiment,
Although the first or second handle member 14, 14a rotates, the first or second hook member 12, 12a
does not rotate while being engaged with the first or second locking member 15, 15a (FIG. 20). Thus, by operating only one actuating member 38, the first
Then, the second unlocking inhibiting means 21, 21a is activated, and both the first and second locking means 103, 103a are prevented from being unlocked, making it impossible to fold down the seat backs 5, 5a from inside the vehicle.

The actuating member 38 is rotated clockwise in FIG. 15 to return the first and second actuating levers 24, 24a to the first position, and the pins 26, 26a of the connecting members 25, 25a are connected to the hook members 12, 12a. When engaged with the abutting portions of the first and second locking means 3, 3
Both a return to the state shown by the solid line in FIG. 15.

Although advantageous embodiments of the present invention have been described above, the present invention is not limited to the above embodiments and can be modified in various ways. For example, in the embodiment shown in FIGS.
It is also possible to omit the actuating member 6 and the actuating member 38 and to allow the operator to actuate the actuating lever 24 directly.

As described above, according to the present invention, it is possible to prohibit the unlocking of the lock device from inside the vehicle as necessary, and to prevent problems such as tampering with the interior of the trunk.
