Safety device for an electric glass-winder of a vehicle of the type having a cable slidable along a guide rail

In a safety device for an electric glass-winder mounted on a door panel having an electric motor fixedly attached to said door panel, a cable drivenly connected to said electric motor and drivingly connected to a window, said cable mounted so as to be slidable along a guide rail mounted on said door panel, a carriage carrying said window fixed to said cable, said safety device adapted to reverse the direction of rotation of said electric motor upon said window encountering a force of a first value opposing the travel of said window, the improvement comprising:

• a) said guide rail movedly mounted on said door panel so as to be capable of being downwardly displaced in substantially vertical translation by said cable due to said force on said window exceeding said first value;
• b) rail maintaining means for maintaining said guide rail in a given position so long as said force remains lower than said first value;
• c) electromechanical means for detecting said force and displacing said guide rail in substantially vertical translation when said force exceeds said first value,
• d) said electromechanical means causing reversal of the direction of rotation of said electric motor when said guide rail is displaced.
