Patent ID: 7040702

Claim:
A tip-up vehicle seat comprising: a seat back attached to a vehicle body; a seat bottom rotatably attached to the seat back, said seat bottom being displaceable between a retracted position where the seat bottom is substantially parallel to the seat back and an available position where the seat bottom is approximately at a right angle with the seat back; a leg member rotatably attached to the seat bottom with a mounting shaft, said leg member being displaceable between a retracted position where the leg member becomes substantially parallel with said seat bottom and a support position where the leg member is approximately at a right angle with the seat bottom; and a lock mechanism arranged to hold the seat bottom at the retracted position; wherein said lock mechanism is connected to the leg member through connecting means so that when the leg member is displaced from the retracted position toward the support position, the lock mechanism is unlocked to permit rotation of the seat bottom into the available position from the retracted position.
