摘要

The adjustment arrangement for a multiple position mechanical system comprises a motor housing (1) for an electro-motor (2), sealed by a cover (3). A connection element (5) is fitted at the side of the motor hoising and includes a curved disc (7) with a central aperture guided by a flange (8) which overlaps a hollow axle (10) at the end of the main motor spindle (9). The flange (8) is held in contact by a spring (32) in an extension of the connection element (5) and is locked against rotation by a gripping piece (34) pressed down by another spring (41) held down by a collar (40) on a threaded adjustment screw (42).
