Abstract
Abstract 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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
166 words
A safety device for an electrical window regulator operated by a d.c. motor comprising a wiring circuit for energizing said window regulator from a d.c. source and including a double-pole reverser operated by buttons permitting to reverse the polarity of the potential applied to the motor so as to cause raising or lowering of a window of a vehicle, a squeezing pressure detector located adjacent the top of the window and responsive to the insertion of an obstacle between the top of the window and the top of the door of the vehicle during raising of the window, a time-lagged reversing relay responsive to said pressure detector when an obstacle is detected for reversing the polarity of the potential applied to said motor for lowering said window during a time interval sufficient to permit removal of said obstacle, and means responsive to said time-lagged relay for preventing inadvertent raising of the window during said time interval by operation of the lowering button of the double-pole reverser.
Claim 2
Dependent Claim
166 words
A safety device for an electrical window regulator operated by a d.c. motor comprising a wiring circuit for energizing said window regulator from a d.c. source and including a double-pole reverser operated by buttons permitting to reverse the polarity of the potential applied to the motor so as to cause raising or lowering of a window of a vehicle, a squeezing pressure detector located adjacent the top of the window and responsive to the insertion of an obstacle between the top of the window and the top of the door of the vehicle during raising of the window, a time-lagged reversing relay responsive to said pressure detector when an obstacle is detected for reversing the polarity of the potential applied to said motor for lowering said window during a time interval sufficient to permit removal of said obstacle, and means responsive to said time-lagged relay for preventing inadvertent raising of the window during said time interval by operation of the lowering button of the double-pole reverser.
Claim 3
Dependent Claim
77 words
A safety device as defined in claim 1, wherein said means includes two switches of said time-lagged relay, one located in the portion of the wiring circuit permitting the lowering of the window by the operation of the lowering button of the double-pole reverser and arranged to open said portion of the wiring circuit, and the other located in the exciting circuit of said time-lagged reversing relay for preventing energization of said relay during the time-lag thereof.
Claim 4
Dependent Claim
43 words
A safety device for an electric window regular in accordance with claim 1, further comprising a selector device permitting to operate successively each of the four window-regulators or other mechanisms of electrical operation, such as the trunk or the hood of the vehicle.
