The door-actuating device driven by a motor and having a two-armed actuating lever (7), one end of which is connected to the motor (2) and the other end (10) of which is connected to the door to be moved, is provided, at the door-connected end of the actuating lever, with connection members (13, 14) which allow an "elastic" coupling of the door. For this purpose, the actuating lever contains a guide track (12), in which a slide element (13) of the connection members is mounted so as to be longitudinally displaceable counter to the force of a spring (20). This element is connected to a link (14), via which the actuating lever is coupled to the door. The guide track is at such an angle relative to the operative direction of the driving force that, if the closing movement of the door is inhibited by an obstacle to movement in or near the closed position of the door, the slide element (13) moves in the guide track (12) counter to the force of the spring (20), the angle between the guide track and the slide element changing in such a way that the closing force determined by the spring force and acting on the door is reduced. <IMAGE> |
