Abstract
A clutch for a power door lock includes an input gear wheel which is formed as a hollow cylindrical input gear wheel, a cam arranged in the input gear wheel and connected thereto, an output gear wheel with coupling drum, and a resilient coupling element controlled by the cam and adapted to be spread. The coupling element is provided with actuating projections. When the clutch is engaged, the actuating projections operatively contact the interior wall surface of the coupling drum. The input gear wheel is journaled on a driving sleeve at which is connected on the one hand a driving disc with driving pins adapted to engage in the coupling element and also a brake disc with an annular spring mounted thereon, to which annular spring is coordinated a stop. The coupling element is a unitary component having a substantially rectangular, elastically deformable frame which inherently is formed as a reset spring, and at two opposite sides of which are provided the actuating projections. The coupling drum presents a noncircular inner wall surface at which the actuating projections engage for transmission of motive power from the drive motor to the control rod actuating the closure.
