Abstract
The invention relates to a controlled-friction device comprising first and second elements mounted to move relative to each other in a sliding direction, wherein the device of the invention includes first and second friction members arranged symmetrically between the two elements in order to rub selectively against the second element, each of the friction members being urged towards a wedging position by a presser member, the first friction member being arranged, in a first direction of relative movement between the two elements along the travel direction, to tend to prevent relative movement between the two elements, and in a second direction to exert on the two elements an opposing friction force that depends on a stress applied against the first wedge member by the presser member; while the second friction member is arranged in the second direction to tend to prevent relative movement of the two elements, and in the first direction to exert on the two elements an opposing friction force that depends on a stress applied to the second wedge element by the presser member; the device further comprising neutralizing means for neutralizing that one of the friction members that is suitable for blocking relative movement of the element in one direction or the other, while leaving the other friction element to exert the opposing friction force.
