Abstract: In a seat, in a state in which tilting of a back main frame around a tilting center is locked by a reclining mechanism, a lower end of a back joint link is turnably joined to a vehicle side. Thus, turning of a first link, a back sub frame and the back joint link is locked, and operation of a back link mechanism is locked. Therefore, a supporting rigidity from rear side of a back side portion can be enhanced by the back link mechanism (the back sub frame), and a crew sitting in the seat can be thoroughly retained.

Abstract: A vehicular seat device assumes, as seat arrangements, a seating state and in which an occupant can sit, an entry/exit state in which the seat cushion (12) is in a standing state, and a retracted state in which a seatback (14) is superimposed on an upper side of the seat cushion (12). The vehicular seat device has a first linking member (21), a second linking member (22) and a drive mechanism (16) that are capable of changing the posture of the seat cushion (12) synchronously with the tilting of the seatback (14). Since the seat arrangement is changed synchronously with the tilting of the seatback (14), it is possible to reduce the burden of operation on an occupant in changing the seat arrangement, while allowing various seat arrangements.

Abstract: In a seat (10), in a state in which tilting of a back main frame (16) around a tilting center (16A) is locked by a reclining mechanism (18), a lower end of a back joint link (26) is turnably joined to a vehicle side. Thus, turning of a first link (22), a back sub frame (24) and the back joint link (26) is locked, and operation of a back link mechanism (14) is locked. Therefore, a supporting rigidity from rear side of a back side portion (12B) can be enhanced by the back link mechanism (14) (the back sub frame (24)), and a crew sitting in the seat (10) can be thoroughly retained.

Abstract: When a seat (10) is to be stowed, a seat pad (28) is moved toward a seat (10) reverse side, pad side portions (32) are rotated toward the seat (10) reverse side with respect to a pad center portion (30), and a center portion (12) and side portions (14) of the seat (10) are contracted. Here, interlockingly with contraction of the side portions (14), a skin (42) is bent and folded in at portions covering distal ends of vertical walls (22) of a wall panel (18) and at second fixing portions (42B). Due thereto, slack of the skin (42) at seat (10) lateral direction end surfaces can be taken in.
