Amendment 1.1.20 Hei 1. The name of the invention is amended as follows. Title of the invention 8-way power seat adjustment device The scope of the utility model registration claims and the brief description of the drawings are amended as follows.

[Claims for Utility Model Registration] (1) A seat track consisting of a lower rail fixed to the vehicle floor and an upper rail that is slidable relative to the lower rail; cushion seats located on a pair of left and right seat tracks; A vertical adjustment mechanism interposed between the seat and the upper rail at the front and rear positions of the cushion seat; a seat back pivotally mounted to the rear of the cushion seat via a tilt angle adjustment mechanism;
A front-back adjustment mechanism that moves the cushion seat and the seat back back and forth through the seat track; a forward-reverse rotation motor that drives the front and rear vertical adjustment mechanisms, inclination angle adjustment mechanism, and front-back adjustment mechanism; forward-reverse rotation of each of these; A drive switch that is provided corresponding to the motor and drives these motors in forward and reverse directions; a sensor that detects the amount of rotation from a reference position of each of the forward and reverse rotation motors or the rotating body driven by the motor; A memory circuit that stores at least one set of sheet set positions detected by these sensors by the operation of a single set switch; An 8-way power seat adjustment device comprising a motor control circuit that is called by operation of one call switch and drives each of the forward and reverse rotation motors to the memorized seat position. (2) In paragraph 2 of the claims for utility model registration,
This 8-way power seat adjustment device includes multiple sets of set switches, memory circuits, and call switches. (3) Scope of claims for utility model registration, paragraph 1 or 2
8-way power seat adjustment device in which the drive switch, set switch, and call switch are provided on a single operation panel.

Claims (1)

[Scope of Claim for Utility Model Registration] (1) A seat track consisting of a lower rail fixed to the vehicle floor and an upper rail that is slidable relative to the lower rail, a pair of left and right cushion seats located on the seat track, a vertical adjustment mechanism interposed between the seat and the upper rail at the front and rear positions of the cushion seat; a seat back pivotally attached to the rear of the cushion seat via a tilt angle adjustment mechanism; The seat adjusting device is equipped with a front-rear adjustment mechanism that moves the cushion seat back and forth via a seat track, and the front and rear vertical adjustment mechanisms, inclination angle adjustment mechanism, and front-rear adjustment mechanism each drive forward and reverse rotation motors. An 8-way power seat adjustment device characterized in that the drive switches for the forward and reverse rotation motors are collectively provided on a display panel. (2) In paragraph 1 of the claims for utility model registration,
Each of the four forward and reverse rotation motors or the rotary body driven by the motor is provided with a sensor that detects the amount of rotation from a reference position, and each position of the sheet detected by this sensor is determined by turning a set switch. The 8-way power seat adjustment device is input to a memory circuit when the call switch is turned on, and read from the memory circuit when the call switch is turned on and reproduced by each forward and reverse rotation motor. (3) In paragraph 2 of the claims for utility model registration,
This 8-way power seat adjustment device includes multiple sets of set switches, memory circuits, and call switches.
