English to French Tech/Engineering Patents apparatus and method for a window regulator

In order to facilitate the movement of the window, the window attachment is secured to a drive means, such as a cable, which is driven by a drum rotated by a motor or a lever actuated manually. In operation and as the drum rotates, a portion of at least one cable is wound onto the drum while a portion of at least another cable is unwound from the drum. Each cable is secured to the window attachment to either pull or allow for (e.g., unwind) slidable movement of the window attachment as the cable drum is rotated by the motor.

Since the cable drum is typically remotely located from the ends of the guide rail the window attachment slides along, pulleys or deflection ramps are located near or at the distal ends of the guide rail so that as the cable drum is rotated the applicable force is applied to the window attachment in order to cause it to slide along the guide rail.

The pulleys provide rotational/sliding support of the cable(s) as they are wound and unwound from the cable drum.

The opposite end of the cable from the cable drum is attached to a carrier, sometimes referred to as a cursor.
