Description

[Detailed Description of the Invention] This invention relates to an improvement of the front seat of a two-door passenger car to make it easier to get in and out of the rear seat.

Conventionally, this type of seat is equipped with a reclining device and a longitudinal adjustment device, and when getting on or off the rear seat or loading/unloading luggage, the seat back is tilted forward and the seat is moved forward to create a passageway to the rear seat. was forming. however,
The passage formed in this manner has the disadvantage that its opening width is not sufficient, and it is particularly narrow near the feet.

In view of the above, the object of this invention is to provide a front seat which allows a wide passage to be formed over the entire passage.

This invention provides a vehicle seat that is equipped with a reclining device and is mounted on a slider that is movable back and forth along a slide rail. A slide pin is fixed to the rear part of the lower surface of the cushion, is biased forward, and is movable in the front-rear direction guided by the second rail, and its base end is located on the front side of the slide pin. The seat cushion is pivotally connected to a lower surface thereof, and its distal end is pivotally attached to the slider, and the distal end is located forward of the proximal end when the seat cushion is in a normal position. The above-mentioned object is achieved by this configuration.

The structure of this invention will be explained below with reference to the illustrated embodiment. In FIGS. 1 and 2, a seat cushion 1 and a seat back 2 constituting the seat are pivotally connected by a reclining hinge 3 to form a reclining device. A slider 5 is slidably attached to the two left and right slide rails 4 fixed to the vehicle body, and the seat cushion is moved by operating a lock mechanism 6 provided between the right slide rail 4 and the slider 5. A front-rear adjustment device is formed that can adjust the position of 1 in the front-rear direction. Inside each of the left and right sliders 5, a channel-shaped second rail 7 that opens inwardly is fixed in the front-rear direction, and a slide pin 8 is attached to each rail 7 so as to be slidable in the front-rear direction and rotatable. The slide pins 8 are each fixed to a rear bracket 9, and the rear bracket 9 is fixed to the rear part of the lower surface of the seat cushion 1. Front brackets 10 are fixed to the lower surface of the seat cushion 1 on the left and right at positions closer to the front than the rear bracket 9, and the base ends of links 11 are pivotally attached to the front brackets 10, respectively. The distal end of the slider 5 is pivoted near the front end of the outer surface of the slider 5, and a stopper 12 is fixed to the slider 5 opposite to the base end of the link 11. When the seat cushion 1 is in its normal position, the stopper 12 is The lower surface of the base end is supported by a stopper 12, and in this case, the tip of the link 11 is formed to be diagonally below the base end.

A lock lever bracket 13 is fixed near the left front end of the lower surface of the seat cushion 1, and a knob 14 and a hook 15 are attached to the lock lever bracket 13.
The hook 15 is connected to a stud 17 whose hook portion is fixed to the front end of the inner surface of the left slider 5 by means of a twist spring 16.
When the seat cushion 1 is in its normal position, the hook portion of the hook 15 and the stud 17 are formed to engage with each other. A protrusion 1 fixed between the inner end of the stud 17 and the inner end of the left slide pin 8 and to the front end of the inner surface of the right slider 5
8 and the inner end of the slide pin 8 on the right side, tension coil springs 19 are respectively installed, so that the slide pin 8 fixed to the lower part of the seat cushion 1 is moved forward by the coil spring 19. energized.

Next, the operation of the vehicle folding seat configured as described above will be explained.

In its normal position, the seat cushion 1 is locked at any longitudinal position on the slide rail 4, and the seat back 2 is locked at an appropriate angle. At this time, the slide pin 8 is located on the backward side of the second rail 7, and the tip end of the link 11 is located obliquely forward and downward with respect to the base end. The biasing force of the tension coil spring 19 that is applied to the slide pin 8 in a substantially horizontal direction acts on the base end of the link 11 via the seat cushion 1, but the biasing force is applied to the base end of the link 11 through the seat cushion 1. The operation of the link 11 is suppressed due to the situation. (However, when the passenger is seated, this biasing force can be countered by his or her weight.) To create a passage to the rear seat, first operate the reclining device and tilt the seat back 2 forward. , then operate the lock mechanism to move the slider 5 to the frontmost position. Next, lock lever knob 1
4, the engagement between the hook 15 and the stud 17 is released, and therefore the inhibition of the movement of the link 11 is also released. At this time, since the distal end of the link 11 is diagonally downward and forward relative to the base end, the link 11
The biasing force acting in a substantially horizontal direction on the base end of the link 11 causes the base end side of the link 11 to rotate upward about the tip thereof. Further, due to this urging force, the slide pin 8 is guided by the second rail 7 and slides forward, and the seat cushion 1 moves forward. Further, as the base end of the link 11 rotates upward, the seat cushion 1 is moved by the slide pin 8.
The front end side rises and moves upward with the axis as the axis, and the rear end side moves forward.
Then, by moving the slide pin 8 to the forward position, the seat cushion 1 completes standing up and moving forward.

When the seat cushion 1 is standing up or rolling forward, the base end of the link 11 is slightly forward of the distal end, so that the seat cushion 1 does not stand up or roll forward in response to a pressing force from directly above or from behind. It acts to maintain a forward rolling posture.

To return the seat cushion 1 to its normal position, push down the front end of the raised seat cushion 1 diagonally backward and downward. As a result, the link 11 rotates to the right (in FIG. 2) about its tip, and the slide pin 8 is moved rearward while the tension coil spring 19 is expanded. As the slide pin 8 moves to the rearward position, the seat cushion 1 assumes its normal position, and at the same time, the link 11 returns to its original position, and the hook 15 engages with the stud 17 to maintain these positions. Further, by raising the seat back 2 and adjusting the position of the seat cushion 1 to an appropriate position, the seat returns to a seatingable state. In this way, as shown in Figure 2, the front seat as a whole moves forward and a large passageway is formed behind it, and the opening width near the footwell, which was previously narrow, becomes wider, making it extremely difficult to get in and out of the rear seat. In particular, when wearing clothes with long hems such as Japanese clothes, there is no risk of soiling them, and it is also convenient for loading and unloading large luggage onto the rear seat.

It should be noted that this invention is not limited to the above description and illustrated examples, and the embodiments thereof can be changed without departing from the technical idea of this invention.
