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.

Seat structure and vehicle

A vehicle seat includes a pad that is made of resin foam, and that forms a seat cushion or a seatback. The pad has a layered structure formed of a surface layer pad that forms a seating surface-side portion of the pad and a back layer pad that is provided on the back side of the surface layer pad. The back layer pad is higher in hardness and lower in density than the surface layer pad.

Vehicle seat

In a seat (), in a state in which tilting of a back main frame () around a tilting center (A) 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 (B) can be enhanced by the back link mechanism () (the back sub frame ()), and a crew sitting in the seat () can be thoroughly retained.

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

Seat structure and seat contraction method

A vehicular seat device has a first linking member () that is linked to a front portion of a seat cushion frame () and to a base member () so as to be respectively pivotable, and a second linking member () that is pivotably linked to a rear portion of the seat cushion frame () and is also pivotably linked to a position on a seatback frame () which is upward of a reclining mechanism () when the seatback is in a standing state. The seat arrangements thereof include a retracted state in which the seatback () is superimposed on the upper side of the seat cushion (), and an entry/exit state in which the seat cushion () is placed in the standing state producing a space for an occupant's entry or exit behind the seat.
