Abstract
A retractable seat to be attached to a floor may include a seat cushion, a seat back rotatably supported on the seat cushion, and a link mechanism for supporting the seat cushion on the 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 can be switched between a use condition and a retracted condition. The front and rear legs respectively have a different link length so as to produce a difference between a rotating range of the front leg and a rotating range of the rear leg. The seat may further include a compensation mechanism for compensating for the difference between the rotating ranges of the front and rear legs within an operating range of the link mechanism.
