Abstract (en)
The present invention relates to a pneumatic window lift meant to be installed on vehicle doors. The window lift can provide four basic functions performed by specific pneumatic circuits, namely: regulating the position, regulating the speed, pinching and braking when the window is at a certain position without being actuated. The speed regulation implies that despite the presence of gravity, which favours the downward motion, the raising and lowering speeds are identical. Pinching is a function that allows a partial lowering and removal of the raising force on the window if it is detected that the elevation is hindered. Lastly, the window can be braked at any position, whether closed or partially closed.
