POWER SEAT DRIVE DEVICE
First Claim
1. A power seat drive device for driving a power seat, comprising:
- a sense electrode operative to sense the proximity of a human body to the rear of the power seat; and
a controller operative to control operation of the power seat based on a sense signal from the sense electrode,wherein the sense electrode is provided in the back portion of the power seat,wherein the controller controls the power seat so as to stop at least one of the sliding movement of the power seat to the rear and the slanting movement of the back portion to the rear where the capacitance indicated by the sense signal received from the sense electrode exceeds a first threshold previously determined.

Abstract
A power seat drive device (100) comprises a sense electrode (10) provided in the back portion (102) of a power seat (101), and a controller (20) operative to control movement of the power seat (101) based on a sense signal from the sense electrode (10). The controller (20) decelerates the speed of movement and provides a warning sound when the proximity distance between the sense electrode (10) and a human body (108) becomes short so as to exceed a decision voltage (Vth1). In addition, the controller stops the movement of the power seat (101) when the proximity distance becomes much shorter so as to exceed a decision voltage (Vth2).
