Abstract: A motor-driven window lifter for a motor vehicle with electronic means to protect against entrapment of body parts in the window opening with at least one spring in the line of force between the drive unit (such as an electric motor or gear) and the window pane is characterized in that the blocking force of the spring corresponds at a maximum to the sum of the displacement force anticipated and the admissible entrapment force and that the spring characteristic when an initial load is exceeded has a decreasing, preferably negative curve, such that the spring enables a relatively long path of the drive unit when the initial load is exceeded.

Abstract: Apparatus for linking a window pane to a window lifter which includes one or more inner jaws for holding the window pane and a pair of outer jaws for holding the inner jaws. The inner jaw or jaws each have one free end and one end pivotably attached at a junction to a base. The outer jaws have hooked ends to engage the junction in a mounting position in which the inner jaws are splayed to accept the window pane. The assembly consisting of the one or more inner jaws, base and window pane is pushed into the outer jaws until the hooked ends of the outer jaws engage the free ends of the one or more inner jaws, thereby locking the assembly in position.

Abstract: In a vehicle door with a cross-arm type window lift and a lock assembly, which can be produced more easily and cost-effectively by employing modular construction and by using individual components for several different functions. The invention is distinguished by the guide rail of the cross-arm window lift simultaneously functioning as the support for the lock assembly, by the guide for guiding the window being integrated in the base body of the lock assembly and by the outer edge of a base plate supporting a window lift having a circumferential profiled sealing section in the interior sheet metal door panel for sealing a mounting opening, so that the protection of electrical/electronic components is provided in the dry space without additional steps.
