Abstract

In an automotive seat assembly including an operating lever device operative to permit a seat back to be inclined forwardly or backwardly, the operating lever device is provided with means for preventing any part thereof from being projected out of the back or front face of the seat back when the latter is inclined forwardly or backwardly.

Claims

1. An automotive seat assembly, comprising:

a seat cushion;

a reclinable seat back supported by said seat cushion, said seat back being mounted for movement between forwardly and rearwardly inclined positions, said seat cushion being associated with means for performing walk-in motion permitting said seat cushion to be moved forward when said seat back is forwardly inclined; and

an operating lever device provided with means for preventing any part of said operating lever device from projecting out of the back or front face of said seat back when said seat back is forwardly or backwardly inclined, said means comprising;

a walk-in lever normally maintained at a predetermined position and connected such that, only when a seat back arm secured to said seat back is forwardly inclined, said walk-in lever is turned about a shaft on which said seat back arm is rotatably mounted;

a transmit plate mounted to be rotatable about said shaft and normally biased to be pressed against a projection provided on said walk-in lever;

a back release lever mounted to be rotatable about a pin provided on said transmit plate and normally biased to be pressed against a stopper portion of said transmit plate, said back release lever being arranged to depress an operating plate associated with means for reclining said seat back, thereby permitting said seat back to be turned; and

a depressing plate secured to said seat back arm and connected such that, only when the seat back arm is backwardly inclined, the depressing plate causes the back release lever to be turned backwardly, whereby said back release lever is prevented from projecting out of the back or front face of said seat back when said seat back is forwardly or backwardly inclined.
