Abstract: To be able to store a seat back and a seat cushion in line from front to back and be able to widely ensure space above a storage position of the seat cushion. In a rear seat (10), when a seat back (18) is rotated to a forwardly collapsed position in a state where a seat cushion (16) has been moved to a storage position, the seat back (18) and the seat cushion (16) are stored in parallel from front to back. Consequently, the seat back (18) and the seat cushion (16) can be thinly stored in an up-down direction of a vehicle. Moreover, the storage position of the seat cushion (16) is set on a rear lower side of a use position, so space above the storage position can be widely ensured.

Abstract: A seat apparatus for a vehicle includes a first lock mechanism switching between a first locked state and a first lock-released state and a second lock mechanism switching between a second locked state and a second lock-released state. The first lock mechanism includes a restraining member and a releasing member. The restraining member restrains a pivotal movement of a seatback at a predetermined angle position, at which the seatback does not interfere with a seat cushion moving between a first position and a second position thereof, when the second lock mechanism is in the second lock-released state. The releasing member is linked to the restraining member and releases a restriction to the pivotal movement of the seatback by being moved in association with a movement of the seat cushion when the second lock mechanism is in the second lock-released state.
