Automotive seat with walk-in device
First Claim
1. An automotive seat with a walk-in device, comprising:
- a seat cushion;
a seat back which is rotatably connected to said seat cushion in a manner inclinable forwardly and backwardly relative to said seat cushion;
a slide rail including a movable rail fixed to said seat and a stationary rail fixed on a floor side of automobile, said movable rail being slidably fitted to said stationary rail, said slide rail further including a biasing means for biasing said movable rail in a forward direction of said seat so as to bias said seat forwardly;
a locking mechanism for locking and unlocking said movable rail at a desired point upon said stationary rail, said locking mechanism being operable by a shaft-like lock lever provided therewith;
a walk-in device for allowing forward and backward movement of said movable rail in response to a forward inclination of said seat back, said walk-in device including;
a lever means which is rotatably, pivotally provided at said movable rail;
an actuator pin which is integrally fixed on said lever means; and
a crank portion formed in said lock lever of said locking mechanism, said crank portion being so disposed as to be in contact with said actuator pin;
a release wire by which said lever means is operatively connected with said seat back; and
a memory device for actuating said locking mechanism to lock said movable rail at a predetermined home point upon said stationary rail when said seat is moved back to its original position,whereby a forward inclination of said seat back causes said lever means of said walk-in device to rotate via said release wire, thereby simultaneously rotating said actuator pin to push and rotate said crank portion, which in turn causes rotation of said lock lever in a direction to actuate said locking mechanism to release a locked state of said movable rail, and thus, said seat is caused to move forwardly by means of said biasing means.

Abstract
An automotive seat with a walk-in device, which permits the forward movement of the seat by inclining the seat back forwardly for a walk-in purpose. The walk-in device in the present invention comprises a rotatable lever plate, an actuator pin fixed on the lever plate, and a crank portion formed in a lock lever associated with a locking mechanism. The actuator pin is in a contact with the crank portion, and as such, when the seat back is forwardly inclined, the rotatable lever plate is caused to rotate, whereby the crank portion is rotated via the actuator pin so as to actuate the locking mechanism to release the locked state of the seat, allowing the seat to be forwardly moved for the walk-in purpose.
