Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a foldable seat that can be folded and stored in a recess provided in a side wall of a vehicle.

[Prior Art] FIGS. 4 to 6 show a conventional folding type seat.

In each drawing, reference numeral 1 denotes a side wall of a vehicle, and a projecting portion 2 projecting inwardly of the vehicle is formed on a lower side thereof. A bracket 3 is fixed on the protruding portion 2, and a base end 4a of a rotating arm 4 is pivotally attached to the bracket 3. The rotating arm 4 is composed of a horizontal piece 5 and an oblique rising piece 6 that obliquely rises from the tip 5a of the horizontal piece 5 to the base end 4a side.
A seat cushion portion 7 constituting a seat is fixed to the 5a side, and a seat back portion 8 is pivotally attached to a tip 6a of a diagonal rising piece 6. An armrest 9 is pivotally mounted at a substantially central position on both sides of the seat back portion 8, and an upright column 11 connected to the armrest 9 via a hinge 10 or the like is provided at a lower portion of the armrest 9 on a tip 9a side. The lower end of the upright column 11 is pivotally attached to both sides of the seat cushion portion 7. Reference numeral 12 denotes a U-shaped leg that is pivotally attached to the back side of the seat cushion portion 7 so as to be able to move up and down, and 13 is a concave portion formed in the vehicle side wall 1, which is formed by folding the seat back portion 8 and the armrest 9 It is formed according to the shape.

With the above configuration, when the seat is folded, the seat back portion 8 is rotated toward the seat cushion portion 7. At this time, the upright columns 11 of the armrest 9 also fall forward and the armrests 9 come to the sides of both sides of the seat back portion 8. By rotating the rotating arm 4 rearward in this state, the seat is leaned against the side wall 1 as shown in FIG. 6, and the seat back portion 8 and the arm rest 9 are stored in the recess 13.

[Problems to be Solved by the Invention] However, according to the conventional folding type seat,
When the armrest 9 is folded, it comes to the sides of both sides of the seat back portion 8, so that the side wall 1 must be provided with a recess for the armrest 9. For this reason the recess
It is necessary to form 13 in a convoluted shape with concavities and convexities, which is disadvantageous in that it takes time to form the concave portion 13.

Therefore, it is an object of the present invention to provide a folding type sheet in which it is only necessary to provide a rectangular concave portion on a side wall, and it is easy to form the concave portion.

[Means for Solving the Problems] A folding seat according to the present invention is provided with an L-shaped piece including a hanging piece having an upper end pivotally attached to a side surface of a seat back portion and a horizontal piece extending from a lower end of the hanging piece. An armrest was connected to the horizontal piece of the L-shaped piece, and a holding member for holding the armrest horizontally was provided.

[Operation] Since the armrest is pivotally attached to the seat back portion via the L-shaped piece, when the seat is folded, the armrests come next to both sides of the seat cushion portion. When moved, the armrest is located on the inner side of the vehicle with respect to the side wall, and it is not necessary to form a recess for the armrest on the side wall.

[Embodiment of the Invention] Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3. The same parts as those of the conventional example are designated by the same reference numerals and the description thereof is omitted.

In each drawing, 14 is a seat back portion of the present invention, which has a frame 15 protruding from both lower sides of a cushion body 14a, an upper end 16a of which is a hanging piece 16 and a lower end 16b of the hanging piece 16. An L-shaped piece 18 composed of a horizontally extending horizontal piece 17 is provided, and an armrest is attached to the horizontal piece 17 of the L-shaped piece 18.
One end 20a is connected to the rear end side of the armrest 19, and one end 20a is pivotally attached to the outer side of the tip end side of the armrest 19, and the other end 20b projects outward from both sides of the seat cushion portion 7 by the width of the armrest 19. A holding member 20 pivotally attached to a shaft 21 is provided, and the holding member 20 holds the armrest 19 horizontally. twenty two
When the seat leans against the side wall,
Is a rectangular recess formed in the side wall 1 for housing the.

With the above configuration, when the seat is folded, the seat back portion 14 is rotated toward the seat cushion portion 7. At this time, the holding member 20 also rotates forward and the armrests 19 come to the sides of both sides of the seat cushion portion 7. In other words, the length of the hanging piece 16 of the L-shaped piece 18 may be set such that the armrests 19 lie on both sides of the seat cushion portion 7 when the seat is folded. Next, with the seat folded as described above, the pivot arm 4 is pivoted rearward so that the seat will move to the side wall 1 as shown in FIG.
The seat back portion 14 is housed in the recess 22, and the seat cushion portion 7 and the armrest 19 are recessed in the recess 22.
It will be located inside the car.

According to the above-mentioned embodiment, it is not necessary to form the recess for accommodating the armrest 19 in the side wall 1, and the seatback portion 14
Since it is sufficient to form the rectangular concave portion 22 corresponding to
The concave portion 22 can be easily formed without any labor for forming the concave portion 22.

[Effects of the Invention] As described above, according to the folding seat of the present invention, the L-shaped member includes the hanging piece having the upper end pivotally attached to the side surface of the seat back portion and the horizontal piece protruding from the lower portion of the hanging piece. Since the horizontal piece of the L-shaped piece is provided and the armrest is connected to the horizontal piece of the L-shaped piece and the holding member for holding the armrest horizontally is provided, the recess formed in the side wall can be easily formed.
