Description

[Detailed Description of the Invention] The present invention relates to a vehicular bench seat with a seat back that can be folded forward.

In general, two-door type vehicles have a structure in which the seat back of the front seat (front seat) folds forward in consideration of ease of getting in and out of the rear seat (rear seat). For example, if the front seat is a bench type seat,
There are types where the seat cushion and seat back are integrated and can be moved forward, and there are separate types where only the seat back is separate and can be reclined and moved forward.

In such bench-type seats,
Separate bag type seat bags, which are easily operated, have been widely put into practical use because the seat bags are individually divided and can be moved forward separately. However, in the case of separate bag types, if the seat bag is not seated in a position that corresponds to each seat bag, the discontinuous part (split part) between these seat bags will hit the passenger's back, making the ride uncomfortable. Although it is equipped with a bench-type seat cushion that allows the seating position to be taken freely depending on the number of people seated, due to the seat back regulation, even if the number of people seated is small, the seating position can be taken freely. Also, they were unable to maintain their posture and were unable to take advantage of the benefits of bench-type seats.

In addition, when the seat back is simply connected horizontally to form a bench type, when the seat back is folded forward and folded over the seat cushion for getting on and off the seat, when it is put back into its original position, the seat back is wide and large. Because it was relatively heavy, it was difficult to operate it easily. This situation is particularly problematic when the seat is of a high back type and has a wide bench type as described above.

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks, it is an object of the present invention to provide a vehicular bench seat whose seat back can be easily operated and which provides comfortable seating.

An embodiment of the present invention will be described in detail below based on the drawings.

A perspective view of the high back bench seat 1 of this embodiment is shown in FIG. 1, a side view in a normal state is shown in FIG. 2, and a side view in a forward folded state is shown in FIG. As shown in these figures, the seat back 2 and seat cushion 3 of the bench seat 1 are separated at the lower part of the seat back 2 (around the waist of the occupant). This seat back 2 is formed integrally with the side parts 4 on both sides of the seat cushion 3, and the seat back 2 and the side parts 4 are formed integrally with each other.
is attached to the seat cushion 3 so that it can be folded forward with the center hinge 5 as a pivot, leaving the seat cushion 3 intact. On the other hand, the seat cushion 3 is fixed to the floor surface by leg portions 6 and a seat adjuster 7 so as to be movable back and forth. Furthermore, a lock device 8 is installed on both sides of the lower part of the seat back 2 to keep it in the raised state, and a lever is provided to release the engaged state of the lock device 8 so that the seat back 2 can be folded down from either side. 9 are provided on both sides of the upper part of the seat bag 2. In addition, 2a in the figure shows a headrest.

To explain these locking mechanisms in more detail, as shown in FIG. 4, an exploded perspective view of one side, the levers 9 on both sides are
are connected by a rod 10, and this rod 10 is connected to a support member 1 fixed to the pipe of the seat bag 2.
1 is supported. Also, this rod 10
A rod 13 is connected to the lever plate 12 via a lever plate 12, and when the lever 9 is pulled in the direction of the arrow, the rod 13 moves upward. Further, the lower end of the rod 13 is connected to one end of a stopper 14 through a long hole 21a provided in the case 21. Stoppa 1
4 has a convex portion 14a, the other end of which is rotatably supported by a shaft pin 15, and is constantly urged counterclockwise by a spring 16.

Also, a catcher 1 is located below the stopper 14.
7 is rotatably supported by a shaft pin 18 and constantly biased clockwise by a spring 19. The upper part of the catcher 17 has a recess 17a that engages with a hook 20 fixed to the seat cushion 3.
is provided. The shaft pins 15 and 18 are supported by a case 21 and a cover 22.
This case 21 is provided with a notch 21b, and the hook 20 engages with and disengages from the catcher 17 through this notch 21b.

In such a bench seat, when either lever 9 of the seat bag 2 is operated forward, the stopper 14 is pulled up, the catcher 17 is rotated clockwise, and the lock with the hook 20 is released. Therefore, seat back 2
The side part 4 is centered around the center hinge 5 along with the side part 4.
The rear seat can be tilted forward until it touches the floor, making it possible to get in and out of the rear seat. And seatback 2 tilted forward
is supported at a constant forward inclination angle by both side portions 4 which become supporting portions when in contact with the floor, so it does not fold over on the seat cushion 3, making it suitable for large and heavy seat bags 2. Even if there is a problem, it can be easily returned to the normal position with a relatively small operating force. Further, in order to return the seat bag 2 to its normal position, the upper part of the seat bag 2 is pushed rearward, and the hook 20 comes into contact with the edge of the catcher 17 and is pushed down to engage with the recess 17a, thereby maintaining the locked state.

As explained above, according to the present invention, a bench-type seat back is provided that can be folded forward and is integrated with the side part of the seat cushion that can serve as a support part by coming into contact with the floor surface. Even if the seat is a bench type seat that provides a comfortable seating position and posture, operations for getting on and off the rear seat can be easily performed.
