Abstract
A retractable seat may include a seat cushion, a seat back rotatably supported on the seat cushion, and a link mechanism for supporting the seat cushion on a floor. The link mechanism includes a front leg and a rear leg that are pivotally connected to the seat cushion and the floor so that the seat cushion and the seat back can be switched between a use condition and a retracted condition. The seat may further include a restraint mechanism provided on the floor for preventing the link mechanism from moving when the seat is in a use condition.
Claims23
A retractable seat, comprising:
- a seat cushion;
- a seat back rotatably supported on the seat cushion;
- a link mechanism for supporting the seat cushion on a floor, the link mechanism including a front leg and a rear leg that are pivotally connected to the seat cushion and the floor, so that the seat can be switched between a use condition and a retracted condition;

- a seat cushion;
- a seat back rotatably supported on the seat cushion;
- a link mechanism for supporting the seat cushion on a floor, the link mechanism including a front leg and a rear leg that are pivotally connected to the seat cushion and the floor, so that the seat can be switched between a use condition and a retracted condition;
- a support member for supporting one of the front and rear legs on the floor when the seat is in the use condition, the support member being separated from the leg to be supported thereby;
- a guide mechanism provided on the floor;
- and
- a lock mechanism provided on the guide mechanism,
- wherein one end of the support member is pivotally connected to the seat cushion via an axis common to the leg,
- wherein the other end of the support member is slidably connected to the guide mechanism, so as to move in forward and rearward directions of the seat,
- wherein the lock mechanism is arranged and constructed to lock the other end of the support member when the seat is in the use condition, and
- wherein the support member, the leg supported by the support member and the floor substantially form a triangle.
