an internal thermal cut-out is tripped to interrupt the power supply to the servo motor.
Servo motor, seat rails, forward and rearward motion
The forward/back servo motor for the seat comprises a DC motor with thermal cutout. If
the servo motor stops under braking or jams, an internal thermal cut-out is tripped to
interrupt the power supply to the servo motor.
Servo motors, seat height and seat angle electric adjustment
The electrically adjustable seat height and seat angle servo motors consist of two DC
motors with integral gearing (worm gear) and thermal cutout. If one of the servo motors
stops under braking or jams, an internal thermal cut-out is tripped to interrupt the power
supply to the servo motor.
