Abstract:
A drive device (2) for adjusting a part of a vehicle between two terminal positions, comprising an electric motor (3) that is in driving communication with an adjustable part, a control switch device (9) that controls the electric motor (3) for stopping the electric motor (3) in at least one predetermined position of the adjustable part, a power takeoff element (31) that is rotatable at least indirectly by the electric motor (3), a switch body (32) that is secured to the power takeoff element (31) and is movable by the power takeoff element (31) along a circular-arclike path, a magnetic-field-sensitive sensor (35), associated with the controlling switch device (9), for controlling the control switch device (9), in which the magnetic-field-sensitive sensor (35) is disposed on a conductor track board (20) along with components of the controlling switch device (9), the conductor track board (20) is disposed inside a housing (6; 7, 8), and is disposed with radial spacing from a circular-arclike path of motion of the switch body (32), and the radial spacing is greater than the dimensions of the magnetic-field-sensitive sensor (35), and at least one magnetic flux guide body (36, 37) is disposed between the magnetic-field-sensitive sensor (35) and the switch body (32), when the switch body is in a switching position.
