  • An electromechanical rotary motor 230 drives a fferspindelgetriebe 235, the output member in the manner of a spindle nut on the screw spindle continuously performs a linear movement along the longitudinal axis of the output shaft of the rotary motor 230 and a Z-shaped guide curve 236 has.
  • the driven member 2 of the adjusting device 200 is guided linearly as a piston in the cylinder and has at its lower end portion a roller which rolls in the guide curve 236.
  • the two end portions of the guide cam 236 are directed perpendicular to the guide straight line of the output member 2 and connected by an inclined guide portion.
  • a pawl transmission for moving the output member 2 is provided.
  • a first rotatably mounted spring-loaded lever 21 is formed as a pawl and cooperates with the output member 2 of the actuator 200 together.
  • the lever 21 is pressed by a leg spring 21 against the rear circular arc-shaped end portion of the driven member 2.
  • a second rotatably mounted spring-loaded lever 22 is arranged at an angle to the first lever 21 and has on the lever 21 facing the longitudinal side of a circular arc sawtooth-shaped switching portion, in which the pawl portion of the lever 21 engages.
  • a compression spring 22f is arranged, which acts on the inner wall of the housing facing the longitudinal side of the lever 22.
  • a solenoid 240 is arranged, whose longitudinal axis is aligned with the longitudinal axis of the compression spring designed as a compression spring 22 f and the linearly movable output member rests on the lever 22.
  • the recesses of the sawtooth-shaped switching portion of the lever 22 have a congruent to the switching portion of the lever 21 shape and are directed so that the driven member 2 can not be pushed back, that is not lowered.
  • the output member 2 is thus locked in one direction.
  • the output member 2 is unlocked by operating the solenoid 240, wherein the switching portion of the lever 21 for the operating period out of engagement with the sawtooth-shaped switching portion of the lever 22 passes.
  • the lever 21 is in each case a tooth in the direction of the output member 2 mortient discharge upon brief actuation of the solenoid 240, wherein the working capacity of the output member 2 is determined by the spring force of the leg spring 21 f.
  • the leg spring 21f moves the output member 2 until the closed position of the door is reached, as in the above in Fig. 9a to 9d describe.
  • the leg spring 21f thus acts as a servomotor, here as a spring motor.
