Description

[Detailed description of the invention] The present invention is a positioning structure for a vehicle seat, particularly a positioning structure in which the seat cushion part can be rotated in the front direction when the seat back part is folded toward the seat cushion part. It is related to.

Conventionally, as shown in FIGS. 1 to 5, a vehicle seat is composed of a seat cushion section 1 and a seat back section 2. In particular, the rear seat S has a hinge section at the lower front side of the seat cushion section 1. 4, the seat cushion part 1 can be rotated in the front direction using the hinge part 4 as a fulcrum, and the seat cushion part 1 can be brought into an upright state. As a result, the space on the side of the rear space 3 of the vehicle can be widened, and large luggage etc. can be carried here. In this case, as shown in FIG.
A rotary rod 6, which can be freely rotated by the By locking with locking pins 8 provided on the vehicle interior side corresponding to both sides of the seat cushion portion 1, it is possible to prevent the seat cushion portion 1 from moving up and down due to vibrations of the vehicle. In order to position the vehicle seat S as shown in FIG. 4, as shown in FIG. ,
By folding the seat back part 2 forward to integrate it with the seat cushion part 1, then by lifting the handle 5 to rotate the rotation rod 6, and by releasing the hook 7 from the pin 8 and lifting it as it is,
When the seat cushion part 1 is rotated forward about the hinge part 4, the seat cushion part 1 and the seat back part 2 stand upright on the floor of the vehicle in an integrated state.

However, according to the conventional vehicle seat positioning structure, it is necessary to operate both the operating handle 10 and the handle 5 of the reclining device 9, which makes the positioning work complicated and the seat S cannot be moved quickly. It had the disadvantage that it could not be positioned exactly.

The purpose of the present invention is to eliminate the above-mentioned drawbacks by making it possible to tilt the seat back part toward the seat cushion part by operating a handle to release the lock of the seat cushion part. This will be explained in detail using examples.

FIG. 6 is a simplified structural diagram showing an embodiment of the positioning structure for a vehicle seat according to the present invention, and the same parts as in FIG. 5 are denoted by the same reference numerals. In the figure, reference numeral 20 denotes a lever fixed to the rotating rod 6. One end of an inner wire 22 of a release wire 21 is connected to this lever 20, and the other end of this inner wire 22 is connected to a ratchet 23 constituting the reclining device 9. It is connected in such a way that it is linked to. The outer wire 24 into which the inner wire 22 is inserted is fixed inside the seat cushion portion 1. Moreover, the above-mentioned reclining device 9
has a ratchet 23 that moves up and down as the operating handle 10 rotates, and this ratchet 23
The rotation frame 25 and the seat back can be held at a predetermined angle of inclination by meshing with the gear 26 of the rotation frame 25 integrated on the seat back side. When the ratchet 23 is moved down to release the engagement with the gear 26, the seat cushion section becomes free, and the seat cushion section 1 is thereby moved toward the rotation frame 2.
A return spring (not shown) provided at 5 causes the seat to fall forward and become integrated with the seat cushion. According to the present invention, by lifting the handle 5, the rotation rod 6 is rotated, thereby causing the inner wire 22 of the release wire 21 to be connected to the ratchet 2.
3 is configured to move downward, the engagement between the ratchet 23 and the gear 26 can be easily disengaged by operating the handle 5, and the seat back portion 2 can be tilted in the direction of the seat cushion portion 1. By further lifting the handle 5, the hook 7 is released from the pin 8, and the seat cushion part 1 can be tilted forward using the hinge part 4 as a fulcrum, and set in the upright state as shown in FIG. Become.

As explained above, according to the present invention, the ratchet of the reclining device is linked via the release wire to the handle 5 for releasing the locked state of the seat cushion, so that the seat back can be moved without operating the operating handle 10. The seat cushion section can be tilted toward the seat cushion section, which simplifies the work of positioning the vehicle seat, and also allows this work to be done quickly. Further, since the structure is simply provided with a release wire, the structure is simple and costs can be reduced.

In the present invention, the handle 5 and the ratchet 23 have been described as being interlocked via a release wire, but they may be configured to interlock using a link, an electromagnetic solenoid, or the like.

Claims (1)

[Scope of Claim for Utility Model Registration] A vehicle seat in which a seat cushion part to which a seat back part is attached via a reclining device is rotatable in the front direction about a hinge part provided on the front side of the seat cushion part as a fulcrum. In the positioning structure, the reclining device 9 locks the inclination angle of the seat back part 2 to a constant angle, and releases the lock of the seat back part 2 by operating the operating handle 10, so that the seat back part 2 can be folded forward. a rotating rod 6 provided at the rear of the seat cushion portion 1 and extending in the vehicle width direction; a handle 5 provided on the rotating rod 6 and protruding toward the rear of the seat cushion portion 1; a wire 22 that connects the tip of a lever 20 provided on the movable rod 6 and the reclining device 9, and operates the reclining device based on the rotation of the lever 20 to enable the seat back portion 2 to fall forward; The reclining device 9 is fixed to the rotating rod 6 and is locked to the locking pin 8 on the passenger compartment side, and the locking pin 8 is rotated based on the rotation of the rotating rod 6 in the direction of unlocking the reclining device 9. A positioning structure for a vehicle seat, characterized by comprising a hook 7 that can be removed.
