Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a rear seat belt device applied to a rear seat of an automobile, particularly a folding rear seat used in a vehicle such as a van type vehicle.

(Prior Art) The above-mentioned folding rear seat includes a seat cushion whose front end is rotatably attached to the vehicle floor, and a forward-tiltable seat back whose lower end is hinged to the rear end of the seat cushion. The rear part of the seat cushion and the seat back are each provided with a locking member for removably locking onto a vehicle body plate. Therefore, to tilt the rear seat forward, disengage the locking member of the seatback, tilt the seatback forward, and then remove the locking member of the seat cushion, so that the seat cushion and the seatback stand upright forward. It depends on the state.

In order to reliably support the rear seat belt when a load is applied to the rear seat belt, such as when the vehicle suddenly stops, one side of the rear seat belt is attached to the side of the vehicle interior, such as the tire house inner panel. The other is fixed to the vehicle floor.

(Problem to be solved by the invention) For this reason, when the rear seat is folded forward as described above, the rear seat belt remains on the vehicle floor.
When the rear seat is returned to its operating position, the rear seat belt is trapped under the rear seat, making it particularly difficult to remove one side of the rear seat belt (the side where the buckle is normally attached), which is attached to the vehicle floor. There's a problem.

For this reason, a structure has been proposed in which one side of the rear seat belt is attached to a lock member for locking the seat cushion to the vehicle body floor, and the rear seat belt is fixed to the vehicle body floor via the lock member (for example, (See Publication No. 55-4249).

However, even with this method, it is necessary to disengage the locking member provided on the seat cushion, which is extremely troublesome to operate as described above.

The present invention has been developed in view of this point, and when the rear seat is tilted forward, the seat cushion is automatically unlocked by tilting the seat back forward, and the rear seat belt is attached to the seat back. and was lifted up,
On the other hand, when the rear seat is returned to use,
An object of the present invention is to provide a rear seat belt device in which a seat cushion is automatically locked when the seat back is placed upright, and the rear seat belt is not caught between the rear seat and the vehicle floor. do.

(Means for Solving the Problems) In order to achieve the above object, the solution means of the present invention includes a seat cushion whose front end is rotatably attached to the vehicle floor, and whose lower end is attached to the seat cushion. The present invention is based on a rear seat configured with a forward-tiltable seat back hinged to the rear end. A striker is provided on the vehicle floor near the rear end of the seat cushion, a hook member that is engaged with the striker is provided on the seat back, and a rear seat belt is attached to the hook member. . The hook member is disengaged from the striker in conjunction with the movement of the seat bag from the upright state to the forward tilted state, and engages with the striker in conjunction with the movement of the seat bag from the forward tilted state to the upright state. It shall be attached to the seat bag as shown above.

(Function) Accordingly, in the present invention, the rear seat belt is attached to a hook member that engages with a striker on the vehicle body floor, and the hook member is attached to the seat back and is engaged with the striker when the seat back is upright, and when the seat back is tilted forward. Since the engagement is released by
When in use, it is latched to the vehicle body floor via the hook member, and when the seat bag is folded and the rear seat is tilted forward, it moves along with the seat bag together with the hook member, and does not remain on the vehicle body floor. Further, the engagement and release of the hook member with the vehicle floor are automatically performed in conjunction with the upright and forward tilting of the seat bag.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

<Example 1> This example is shown in FIGS. 1 and 2. rear seat 1
consists of a seat cushion 2 and a seat back 3. The lower front end of the seat cushion 2 is rotatably attached to the vehicle body floor 5 by a hinge mechanism 4 such as a hinge. The seat back 3 has its lower end hinged to the rear end of the seat cushion 2 by rear seat back hinges 6 (however, only one is shown) attached to both sides of the rear end of the seat cushion 2, and The upper end portions of both sides (however, only one side is shown) are removably locked to appropriate positions on the vehicle body, such as a rear suspension tower 8, by seat backlock members 7.

The seat back lock member 7 includes a bracket 10 attached to both sides of the seat back 3, a release lever 12 rotatably supported on a support shaft 11 of the bracket 10, and a striker 13 attached to the rear suspension tower 8. Become. The release lever 12 has an engaging claw 1 that engages with the striker 13.
4 and an operating handle 15, and is constantly biased by a spring 16 in the direction of engagement with the striker 13.

Reference numeral 20 denotes a rear seat belt device, which includes a hook member 22 attached to the rear panel 21 of the seat back 3, etc., a striker 24 attached to a recess 23 formed in the vehicle body floor 5 near the rear end of the seat cushion 2; The hook member 22
One rear seat belt 25 is attached to the rear seat belt 25.

The hook member 22 has one end attached to the rear panel 21.
A mounting flange 26 is fixedly attached to the seat, and an engaging claw 27 that engages with the striker 24 is formed at the other end. The engaging pawl 27 is attached to the seat back 3 so that it is disengaged from the striker 24 when it is engaged from the rear and the seat back 3 is tilted forward about the rear seat back hinge 6.

The attachment of the hook member 22 to the seat bag 3 is not limited to the rear panel 21, but may be attached to the frame of the seat bag 3 (not shown). Also, the rear seat belt 25
Although not shown, the other one is attached to a suitable position on the vehicle body. In the figure, 28 is a buckle attached to the tip of the rear seat belt 25.

In the above structure, when using the rear seat 1,
The seat bag 3 is in an upright state, and the engaging pawl 27 of the hook member 22 is engaged with the striker 24 from the rear. Therefore, even if an impact load is applied to the rear seat belt 25 due to a sudden stop or the like, the rear seat belt 25 is locked to the vehicle body floor 5 via the hook member 22 and is strongly supported against the load, and the rear seat belt 25 is The hook member 2
2 to the vehicle body floor 5 and will not float up.

Next, when folding the rear seat 1 and tilting it forward, the seatback lock member 7 is disengaged and the seatback 3 is tilted forward, so that the hook member 22 is also rotated about the rear seatback hinge 6. Then, the engagement with the striker 24 is released. Therefore, the seat cushion 2 can rotate around the hinge mechanism 4 when the seat back 3 is folded, and the rear seat 1 can be folded forward into an upright state as shown by the chain line in FIG. Therefore, the rear seat belt 25 is not pulled up together with the hook member 22 and remains on the vehicle floor.

<Example 2> The above-mentioned Example 1 showed an example in which the rear seat belt 25 was of a band type, but in this example, the present invention is applied when a rigid type rear seat belt is used. It is shown in FIGS. 3 to 5.

The rear seat belt 31 has a buckle 33 attached to the tip of a rod 32. The other end of the rod 32 is non-rotatably secured to a hook member 34. The hook member 34 has its upper end rotatably supported by a pin 37 on a bracket 36 attached to a mounting portion 35 such as a rear panel or seat back frame attached to the rear panel of the seat bag 3, and a lower end thereof as in the previous example. An engaging pawl 39 is formed to be engaged with a striker 38 attached to the recessed portion 23 of the vehicle floor 5. Similar to the previous example, the rear seat belt device 30
is the rear seat belt 31 and the hook member 3.

The hook member 34 is constantly urged by a spring 40 in the direction of engagement with the striker 38, and the rear seat belt 31 is attached to the seat cushion 2 at a predetermined angle.
and the seat back 3 (solid line position in Figure 5).

As in the previous example, the lower front end of the seat cushion 2 is rotatably connected to the vehicle body floor 5 by a hinge mechanism 4, and the seat back 3 is locked to the rear suspension tower 8 by a seat back lock member 7.

In the above structure, if the rear seat belt 31 gets in the way when using the rear seat 1, it can be pushed down (toward the seat cushion side).
The rear seat belt 31 is rotated together with the hook member 34 about the pin 37, and when released, the spring 40 returns the rear seat belt 31 to a predetermined position, and the engaging pawl 39 is engaged with the striker 38. Therefore, when the rear seat belt 31 is in use, when an impact load is applied to the rear seat belt 31 due to a sudden stop, etc., the hook member 34
The rear seat 1 is firmly supported by the vehicle floor through the seat, and the rear seat 1 does not float up.

Next, when folding the rear seat 1 and tilting it forward, the seatback lock member 7 is disengaged and the seatback 3 is tilted forward, so that the rear seatbelt 31 is pushed toward the seat cushion 2 by the seatback 3. The hook member 34 is then rotated about the pin 37, thereby disengaging the hook member 34 from the striker 38. Therefore, the rear seat 1 can be folded forward into the upright position shown by the chain line in FIG. 5, as in the previous example.

(Effects of the invention) As described above, according to the invention, the rear seat belt is attached to the hook member, and the hook member is attached to the seat back and is provided so as to be able to engage with the striker attached to the vehicle body floor. Since the rear seat belt is engaged with the striker when the vehicle is standing upright, and is disengaged when the seatback is tilted forward, the rear seatbelt is engaged with the vehicle body floor via the hook member when in use, and the seatback is folded. When the rear seat is folded and tilted forward, it moves along with the seat back together with the hook member and does not remain on the vehicle floor. Further, since the hook member is automatically engaged with and released from the vehicle floor in conjunction with the upright and forward tilting of the seat back, the operability for changing the rear seat position is significantly improved.
