Description

[Detailed description of the invention] This invention is a vehicle seat in which the seat back is bendably connected to the cushion seat, and when the cushion seat is moved forward and the seat back is moved backward, the entire surface can be made almost flat. It is characterized by:

2. Description of the Related Art In general, seat devices for vehicles in which the seat back is placed on the rear side and the front and rear seats are continuous to form a bed-like structure are becoming popular.

However, in this case, the cushion seat remained fixed and only the seat back moved rearward, so the front part of the cushion seat was formed to be higher than the seating performance of the cushion seat, and the rear part was lower than that.

Therefore, it was impossible to make the entire surface flat.

That is, in Fig. 1, the front part a' of the cushion seat a is high, and the rear part a'' is lower than that, and if this is connected to the front part of the cushion seat of the rear seat with the seat back b on the rear side, As shown by dotted line C in Figure 1, the front part a/, a/ position of the cushion seat is high, and the rear part a'', a''
The bed surface had a height difference in the a'' portion, which was not comfortable to sleep on and was not desirable.

In order to eliminate these drawbacks, the present invention is designed to make the bed surface almost horizontal and flat by making the cushion seat slightly movable and vertically movable as well. This will be explained in detail with reference to FIG. 2, which is shown as an embodiment.

Reference numeral 1 denotes a seat, which is separated by a cushion seat 2 and a seat back 3 foldably connected to the cushion seat 2.

Similar seats 1' are also provided at the rear as shown by 2' and 3'.

These cushion seats 2 and 2' have legs 5 so as to be able to move along upper chord-shaped rails 4 and 4' that are curved upward in a convex shape.
, 5'.

However, when driving a general vehicle, the seat back 3 should be erected as shown by the chain line in Figure 2, and the cushion seat should be seated (2.2).
It is also used by being fixed on the rails 4 and 4' with a fixing device (not shown, as any known fixing device will suffice) so that seating is easy.

If you want to use seats 1 and 1' like a bed for napping in the car, etc., bend the cushion seats 2 and 2' slightly and curve the rails 4 and 4'.
When moving slightly forward along the curved rails 4, 4', the front parts 2a, 2 of the cushion seats 2, 2' move along the curves of the curved rails 4, 4'.
The 'a part will be located slightly lower, and the rear part 2b,
2'b is located slightly upwards.Thus, when the seat back 3 is folded back and connected to the front part 2'a of the rear seat, the bed surface is almost horizontal as shown by the dotted line d in Figure 2. It can be a flat surface.

In this invention, the cushion seat is made movable and moved along the upper chord-shaped rail curved upward in a convex shape, so that the cushion seat changes not only back and forth, but also up and down, making it possible to change the entire shape. This results in a flat bed surface.
