Safety device for electric cable window raiser of a vehicle, the window sliding along a guide rail.

摘要

The window operating mechanism has a cable sliding the length of a guide rail (6) to raise and lower the window. A magnet (9) holds the rail in its normal position, attracting a ferromagnetic bracket (13) attached to the rail. If a force exceeding a preset level opposes the movement of the glass the magnetic force is overcome and the rail released. The rail (6) can then be drawn vertically down by the cable. An electromechanical detector (14,15) monitors the force on the glass and automatically reverses the drive motor if the force is excessive.
