(5) Seat supporting the seat (2) and the backrest (3) above
(1) an intermediate portion on both sides of the seat portion (2), a front end portion of the seat under frame (5), a rear end portion on both sides of the seat portion (2), and the seat under frame (5). The back portion (3) is reclineable and foldable on the seat (2), and is connected to the intermediate portion by links (7, 8), and the back portion (3) is placed on the seat (2). Link in a folded state
The rear end of the seat (2) is provided with a vehicle seat (1) in which the rear end of the seat (2) is prevented from falling into the seat underframe (5) when the vehicle is in a vertical rising state via (7, 8). Things.

[0005]

[Function] When the backrest (3) is folded over the seat (2) in the horizontal use state and the front end of the seat (2) is lifted upward together with the backrest (3) in this state, the seat (2) The link (7) (front link) connecting the middle portion on both sides of the seat 2 and the front end of the seat under frame (5) rotates forward and upward, and the both sides of the seat (2) The link (8) (rear link) connecting the end portion and the intermediate portion of the seat underframe (5) is rotated from the diagonally rearward position to the diagonally forward position, and the seat ( 2) Support the rear end (lower end) above the seat underframe (5). Therefore, the seat (2)
The rear end of the seat under frame is vertical
(5) Since it does not fall into the inside and does not interfere with the wheel house W protruding on both sides of the vehicle body, there is no need to cut out both rear corners of the seat (2).

[0006]

1 to 9 show one embodiment of the present invention. The seat (1) shown in the figure is a third seat of a one-box type automobile, and a seat (2) and a backrest that is supported by the seat (2) via a reclining device (4) so as to be reclined. The seat (2) is supported on a pair of left and right seat underframes (5).

The seat underframe (5) is slidable back and forth along a slide rail (6) on the floor F. In order to avoid interference with the wheel house W protruding on both sides of the vehicle body, the seat underframe (5) is As shown in FIG. 2, the leg portions (5A, 5B) of the seat underframe (5) are
It is located inside.

The seat (2) is supported on a seat under frame (5) having a pair of left and right legs (5A, 5B). The seat (2) and the seat under frame (5) are supported. The left and right links (7, 8) are inserted between the upper and lower ends of the seat under frame (5) and the lower edge of the seat (2). The rear link (8) is passed between the upper middle portion of the seat underframe (5) and the rear edge of the lower edge of the seat (2).

FIGS. 1, 2 and 5 show a normal use state of the seat (1). In this state, the backrest (3) is adjusted to an arbitrary reclining angle via the reclining device (4), and the striker (9) of the seat (2) is connected to the hook of the seat underframe (5) as shown in FIG. (Ten)
And the pin (11) of the seat (2) engages with the engaging portion (12) of the seat underframe (5) and is fixed on the seat underframe (5) of the seat (2). . From this state, FIG.
Then, as shown in FIG. 6, the backrest (3) is folded forward and folded on the seat (2). And in this state okay hook (10)
Is lifted, and both the seat (2) and the backrest (3) are lifted with their front ends raised to the vertical state shown in FIGS. 4 and 7.

When the seat (2) and the backrest (3) are to be raised, the front link (7) pivots forward and upward as shown by arrows in FIGS. The side link (8) pivots from the diagonally rearward position to the diagonally forward position, and thus the seat (2) and the backrest (3) are supported in a folded state above the seat underframe (5). In this state, the striker (13) of the rear link (8) is locked to the hook (14) of the seat under frame (5) as shown in FIG.

When the seat (2) and the backrest (3) are folded and vertically raised, as shown in FIG.
The rear end of (2) does not fall into the seat underframe (5), so that even if the rear corners of the seat (2) are not cut off, the seat (2) and the wheel house W are not cut off. The sheet can be slid without interference.

Although the present embodiment relates to a third sheet, the present invention is not limited to this, and may be applied to other sheets such as a second sheet.

[0013]

According to the present invention, the seat protrudes from both sides of the vehicle body even if the rear corners of the seat are not notched, and the seat is slid in the folded state of the seat and the backrest and in the vertical upright state. There is no interference between the wheel house and the seat.
