Abstract
A vehicle seat is provided in which a seat back is constrained from tilting down when a seat cushion is moved to a position in which the seat back cannot be tilted down. The vehicle seat includes a base frame, a seat cushion frame (3) horizontally movable relative to the base frame between a first position and a second position different from the first position, a seat back frame (4) rotatable relative to the seat cushion frame (3), a lock member (5) configured to constrain the seat back frame (4) from tilting rearward, and an unlock mechanism (6) configured to release a lock applied by the lock member (5) when the seat cushion frame (3) is moved from the first position to the second position.
Claims14
A vehicle seat comprising a base frame and a seat frame disposed above the base frame, the seat frame comprising:
- a seat cushion frame slidable relative to the base frame between a first position and a second position different from the first position;
- a seat back frame rotatable relative to the seat cushion frame;
- a lock member configured to constrain the seat back frame from tilting rearward;
- and
- an unlock mechanism configured to release a lock applied by the lock member, in a manner coordinated with a motion of the seat cushion frame from the first position to the second position,
- wherein the lock member is configured to be movable to a lock position in which the seat back frame is constrained from tilting rearward, and to an unlock position in which the seat back frame is allowed to tilt rearward,
- the unlock mechanism comprises a pull member connected to the lock member, and an engageable portion provided at the base frame, the engageable portion being engageable with the pull member, and
- engagement of the engageable portion with the pull member occurring while the seat cushion frame is moving from the first position to the second position causes the pull member to be pulled, which in turn causes the pull member to move the lock member from the lock position toward the unlock position.
