Abstract
A drive for a door bolt of a motor-vehicle door latch has a pivot shaft fixed on the bolt offset from the bolt, a motor having a rotary output, a transmission having an input connected to the motor output and an output shaft, and a coupling directly joining the output shaft of the transmission to the pivot shaft for rotation of the bolt by the motor. The transmission output shaft and the pivot shaft are coaxial. The shafts have confronting ends formed with respective sets of axially projecting teeth that axially overlap, engage in each other, and form the coupling. These teeth are of generally triangular cross section and the teeth of the bolt shaft are angularly interleaved with the teeth of the transmission shaft. In addition a star-section element centered on the axes is formed with a plurality of radially open pockets each receiving a respective one of the teeth. This star element is elastomeric.
