Abstract
The invention relates to a bidirectional drive for rotating in the one or the other direction of drive a drive wheel which is linked with an adjusting device. The bidirectional drive includes a drive lever which can be rotated about a drive axis, starting from an initial position, in the one or the other direction. The lever is linked with a coupling element for expanding a spring element that is at least partially supported by the cylindrical drive surface of the drive wheel and that entrains the drive wheel in the peripheral direction when the drive lever is moved away from the initial position, while the spring element is no longer supported by the cylindrical drive surface of the drive wheel and the drive wheel is not entrained when the drive lever is returned to the initial position. The coupling element includes expansion cams that can be tilted about an axis spaced apart from the drive axis. The expansion cams expand the actuation lever which is linked with the spring element in such a manner that the spring element which is supported by the cylindrical drive surface of the drive wheel is expanded.
