しても、簡単かつ確実に格納されうる。 Therefore, when the seat bottom lock is released, the seat back lock is also released, making it unnecessary to release the seat back lock. If the seat bottom lock and the seat back lock are released at the same time in this way, you can fold the seat back 15 forward after lifting the seat bottom, or vice versa. You can also lift
Furthermore, the seat bottom 13 can be lifted while folding the seat back 15. In other words,
This seat 2 can be easily and reliably stored even by a person who is inexperienced in storing the seat.

ることになる。 In the above embodiment, the seat back lock is composed of a lock pin 27 of the seat back 15 and a lock piece 26 that removably engages with the lock pin 27. Generally, the reclining device includes a sector gear 31 fixed to an upper bracket 30, and a sector gear 31, as shown in FIGS. 3 and 4. The seat bag 15 is configured to be able to change and adjust the inclination angle of the seat back 15 by engaging and disengaging a lock gear 33 which is rotatably supported by a lower bracket 32 and can be freely engaged and disengaged from the seat back 15 by rotating an operating lever 34. Therefore, the seat back lock can be moved to the reclining device 3
It can also be the lock itself. In that case, for example, the locking piece 20 and the striker 21 may be disengaged (the seat bottom lock may be unlocked).
The interlocking member that detects this will unlock the reclining lock of the reclining device 35.

A seat bag is attached to a nutcle bracket which is attached so as to be tiltable forward about an axis, and a seat bag is attached to the seat bag so that it can be tilted forward about a second axis located above the first axis.
Since the seat back lock is released at the same time as the seat bottom lock by an interlocking member that is linked to the movement of the operating lever, even with a simple structure,
Easy to operate, anyone can easily fold and store it. Furthermore, when folding and storing the seat, the seat bag can be folded forward around the second axis located above the first axis, so the seat bag can be folded thinly along the seat bottom, and the seat can be attached to the vehicle floor. When the seat is rotated around a substantially parallel lateral axis and stored forward, the space secured behind the stored seat can be more effectively expanded.
