Abstract
A seat device that can reliably regulates a reclining operation when in a long state where a back of a seat is along a wall. The seat device (10) that can convert the state of the seat (1) includes a reclining mechanism (50) that can tilt a backrest (3) of the seat (1), wherein an operation of tilting the backrest (3) by the reclining mechanism (50) is disabled when the seat (1) is in the long state.
Claims3
A seat device that can convert a state of a seat, comprising:
- a reclining mechanism that can tilt a backrest of the seat;
- an operation part that performs an operation of tilting the backrest by the reclining mechanism;
- a lock mechanism that can restrain the operation part in an inoperable manner;
- an engaging portion provided in a fixed side of the seat;
- and
- an engaged portion that is provided in a movable side of the seat, and can be displaced by being engaged with the engaging portion when the seat is in a specific state,
- wherein an operation of tilting the backrest by the reclining mechanism is disabled when the seat is in the specific state,
- the lock mechanism restrains the operation part in an inoperable manner when the seat is in the specific state, and
- the engaged portion and the lock mechanism are connected to each other via transmission means, displacement of the engaged portion is transmitted to the lock mechanism via the transmission means, and the lock mechanism restrains the operation part in an inoperable manner.
6 more elements
A seat device that can convert a state of a seat, comprising:
- a reclining mechanism that can tilt a backrest of the seat;
- a rotation mechanism that rotates the seat about a rotation axis;
- and
- a sliding mechanism that advances and retracts the seat together with the rotation mechanism from a fixed side,
- wherein an operation of tilting the backrest by the reclining mechanism is disabled when the seat is in a specific state,
- the state of the seat can be converted by interlocking of the rotation mechanism and the sliding mechanism between a long state where a back of the seat is substantially parallel to and along a wall and a cross state where the back of the seat is away from the wall in an orientation substantially orthogonal to the long state, and
- the specific state of the seat corresponds to the long state.
