It is proposed that the friction engagement elements (8, 9, 10) be arranged concentrically relative to each other at least in portions and that the central friction engagement element (8) be a tolerance ring (13) and be clamped radially between the two additional elements of the friction engagement elements (9, 10) in order to provide a friction engagement connection.

The disclosure relates to an overload coupling for an actuating mechanism for actuating a charging, fueling, or service flap on a charging, fueling, or service compartment that is or can be received on or in a body component of a vehicle. The overload coupling includes a drive-side coupling element and an output-side coupling element and, in an engaged state by means of a form-fit and/or force-fit lock, transfer a torque and thus a drive movement from the drive-side coupling element to the output-side coupling element. When a critical torque to be transferred is reached or exceeded in the event of an overload, to lift the form-fit and/or force-fit lock between the drive-side coupling element and the output-side coupling element.

In an example, a device includes a base unit, a cover unit, and a hinge assembly to couple the cover unit to the base unit The hinge assembly is moveable between a folded position and an unfolded position. The hinge assembly includes a channel, an annular holder disposed in the channel, a shaft engaged with the annular holder, and a hydraulic cylinder coupled to the shaft. The hydraulic cylinder is to move the shaft along a longitudinal axis of the shaft, based on a movement of the hinge assembly between the folded position and the unfolded position, to vary an operating torque of the hinge assembly.

The invention comprises a door closer (1), a slide rail (3) and an arm (2). The arm is connected to the door closer (1) and to the slide rail (3). The slide rail is provided with a hold open device (4) in order to keep a door open. The arm (2) comprises an outer arm (8A, 9A) and an inner arm (8B, 9B). The inner is situated partly inside the outer arm in a sliding manner. The arm (2) also comprises a spring arrangement (11) in order to hold the inner arm (8B, 9B) in a normal position in the outer arm (8A, 9A), and a release device (10A, 10B). The release device is arranged to release the inner arm (8B, 9B) from its normal position when an external force being strong enough to active a release of the release device (10A, 10B) drives the inner arm (8B, 9B) out from the outer arm (8A, 9A).
