Filed: 1993-06-30
Abstract: PURPOSE:To bend the seat cushion side so that a person gets on and off easily and to reduce an oppressive sensation to the thigh by controlling a motor and detaching a hinge stopper, when a door is opened. CONSTITUTION:When a door is opened, a door sensor 10 senses it and sends a signal to a control circuit 11, and a motor 8 is turned on. As a result, a hinge stopper 6 is moved to a main body side frame 2 against a return spring through a wire 7 and detached from a hinge 4. Accordingly, a cushion side frame 3 becomes bendable against the main body side frame 2 and a seat cushion side is bent against elasticity of a cushion spring 5, when person's weight is applied. At the time of getting off a car, the thigh of a person does not receive strong oppression, therefore, the person does not feel uncomfortable. On the other hand, when the door is closed, the door sensor 10 senses it and the control circuit 11 turns off the motor 8. As a result, the hinge stopper 6 is fitted to the hinge 4 by an action of the return spring and the seat cushion side is not bent by person's weight.
