Abstract
The bearing module (10) is used to support an actuating element which can be displaced counter to the force of at least one return spring (32) with a force hysteresis due to friction. With previous bearing modules, complex friction mechanisms which ensure the desired hysteresis are provided in addition to the return springs. To reduce the number of parts necessary for a bearing module, the proposal is that the force should be transmitted from the return spring (32) via a friction element (24) which slides on a friction surface (28) assigned to the return spring (32) during the displacement, either tensioning the spring (32) or being returned by it. The direct production of hysteresis in the return mechanism reduces the number of components and hence the costs of production for the bearing module (10).

A bearing module for an actuating element which can be displaced counter to the force of at least two return springs (32) arranged in a redundant manner, a force hysteresis produced by friction occurring when the actuating element is actuated, wherein force is transmitted (12, 16, 22) between the return springs (32) and the actuating element via friction elements (24) each of said friction elements slide on a friction surface (28) assigned to a free end (30) of each of the return springs (32) as the actuating element is displaced, the return springs (32) either being tensioned by the actuating element as a function of the direction of displacement or being returnable by the restoring force of the return springs (32).
A bearing module for an actuating element, wherein the actuating element is the accelerator pedal of a motor vehicle, which can be displaced counter to the force of at least two return springs (32), arranged in a redundant manner, a force hysteresis produced by friction occurring when the actuating element is actuated, wherein force is transmitted (12, 16, 22) between the return springs (32) and the actuating element via friction elements (24) each of said friction elements slide on a friction surface (28) assigned to a free end (30) of each of the return springs (32) as the actuating element is displaced, the return springs (32) either being tensioned by the actuating element as a function of the direction of displacement or being returnable by the restoring force of the return springs (32).
