Abstract: An adjusting device serves for moving a moveable part into various positions, for example a side ventilator window of a motor vehicle. A servomotor (14) drives a spindle drive (18) which comprises essentially a spindle (24) having an external thread (26) and a sleeve part (28) which surrounds the spindle and has a corresponding internal thread (30). When acted upon by an external force, axial play in the region of the spindle drive (18) may lead to noise being produced; in order to avoid the noise, one (30) of the two threads comprises separate threaded parts (32, 36), and an elastically prestressable element (38) is provided with the aid of which an axial force can be produced between the two threaded parts (32, 36). The axial force causes the two threaded parts (32, 36) each to bear against opposite flanges of the external thread (26), so that the axial thread play is eliminated.

Abstract: A lock, suitable for use in a car door, has a rotary latch which cooperates with a locking wedge, or the like, and can be locked by a locking pawl in a locking position. The pawl is actuatable by a setting device for bringing the rotary latch at least into an open position. In order to provide a lock which is of improved efficiency and is both compact in construction and operates reliably, transmission elements are arranged between the pawl and the setting device for transmitting movement of the setting device, in stepped-down fashion, to the pawl.

Abstract: An apparatus is disclosed for electrically locking the doors of motor vehicles, wherein at least one motor is supported in a driver door and the motor is coupled with a lock mechanism by means of a connecting element, with a first switch coupled with the motor to be actuated thereby and a second switch coupled with the lock mechanism to be actuated thereby and also coupled with the first switch and with the motor, and the switches are connected with at least one additional motor coupled with a further lock mechanism. Structure is included to change the direction of the force exerted by the motor on the lock mechanism, for locking or unlocking the doors, respectively.
