Abstract

PURPOSE:To reduce the stopping shock by braking a motor upon elapse of predetermined time after power interruption to a motor during moving a seat thereby gradually decelerating the seat. CONSTITUTION:Upon turning off of a slide switch 18, a forward rotation switch 27 is turned off thus to turn off a delay switch 31. Consequently, power supply to a motor 17 is interrupted to advance a seat cushion 12 while braking gradually (deceleration) through the weight of passenger. Upon turning on of a switching transistor 30 through a microcomputer 20 upon elapse of predetermined time to turn on the delay switch 31, the motor 17 mill stop quickly.
