BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a memory device which is a workpiece of a vehicle seat, and more particularly, to a memory device in which a seat occupancy position is set for a seat occupant, Which is a work of a vehicle seat capable of returning a seat to a predetermined seating position when returning the seat back to the home position.

Generally, a seat of an automobile includes a seat cushion that supports a load of a passenger and is slidably installed back and forth on a floor of a room, and a seat back which is rotatably installed to support a back of a passenger seat.

The seat includes a device for locking a seat rail for movably coupling the seat to the floor of the vehicle so as to adjust the position of the seat by pulling or pushing the seat back and forth to match the body shape of the driver or the rider, A recliner for adjusting the angle of the seat back is provided.

In recent years, in the case of a three-door vehicle or a coupe vehicle, the front seat is slid forward to increase the opening area of the door to facilitate boarding. Especially, the seatback is folded together with the sliding of the seat to maximize the expansion of the space. Sliding the front seat in this way is called a walk-in function.

As described above, techniques having a work-in-sheet function are disclosed in Korean Patent Publication Nos. 10-2006-0010948 (Patent Document 1) and Korean Patent Registration No. 10-0649090 (Patent Document 2).

Among these patent documents, a seat having a walk-in function disclosed in Patent Document 4 is a work that is a work to be mounted on a seatback. When a passenger operates the lever, a cable as a work is pulled to operate the reclining device, It folds forward. At this time, the bracket as the work is pivoted by the communication bracket of the seatback, and the sliding cable is pulled to release the locking lever of the seat rail. Then, the seat slides forward and backward of the vehicle. At this time, the occupant pushes the seat toward the front of the vehicle to ride on the rear seat.

The seat having such a walk-in function as described above can be used as a work-in-seat after the work-in-seat is slid forward to allow the occupant to ride on the seat, The position of the set seat is initialized.

Therefore, the seat having the conventional walk-in function has a problem in that after the occupant performs the work-in operation, the seat is moved to the home position and then the position of the seat is set to match the body shape of the occupant.
