Abstract
A window regulator device for automatically elevating or lowering a window glass of an automobile is equipped with a safety device that operates when a human arm, for example, is sandwiched between the glass and its window frame. The regulator device consists of a motor for moving the glass up or down, a detector circuit for sensing whether the motor is locked, a reversing circuit connected to the detector circuit for reversing the motor, a latching circuit for maintaining the motor energized, and an operated switch for permitting the motor to move the glass up or down.
