Abstract
Arrangement, in particular for a motor vehicle, having a closing device which can be pivoted about an axis between a closed and an open position, for example a boot lid or a tailgate, a compensating device acting on the closing device, in particular at least one gas-pressure spring, which is pretensioned and a counter-force opposes the weight of the closing device, and a motor-driven drive which can be operated at least unidirectionally, in particular bidirectionally, in order to pivot the closing device about the axis in at least one direction, wherein the motor-driven drive is designed to be repellable, in order to facilitate manual actuation of the closing device. Friction means are provided, which act on the closing device both during manual actuation of the closing device and during actuation by the drive at a preset friction torque, wherein the friction torque within the pivoting range of the closing device or of a part range thereof is greater than the extent of the difference of a first torque produced by the weight of the closing device and a second torque produced by the counter-force of the compensating device.
