Abstract
A safety device for electric glass-winders of the cable type employs a guide rail movably mounted on the door panel of a vehicle so as to be capable of being driven downwardly in vertical translation by the cable upon encountering a force opposing travel of the glass which exceeds a predetermined value. The rail is maintained in its normal position by, for example, a magnet which attracts a tab of ferromagnetic material fixed to the rail. A switch forming part of the electrical supply circuit for the winder motor cooperates with the rail and reverses the direction of rotation of the motor when the rail is displaced from its normal position to a lower position. The electromechanical safety device is inexpensive and simple to manufacture.
