Sicherheitsvorrichtung fuer einen elektrischen Scheibenheber

摘要

A safety device for an electrical window regulator comprising a wiring circuit for energizing the window regulator including a double-pole reverser operated by buttons permitting raising or lowering of the window of a vehicle, a pressure detector responsive to the insertion of an obstacle between the top of the window and the top of the door of the vehicle, and a time lagged reversing relay responsive to the pressure detector for reversing the conductors of said wiring circuit for lowering the window. The safety device includes a device responsive to operation of the time-lagged relay for preventing the double-pole reverser from causing raising of the window during the time-lag of the relay.
