The invention relates to a controlled-friction device including: a first element on which a second element is mounted so as to slide along a sliding axis (X); and friction retaining means disposed so as to exert a resistive force between the two elements, which force opposes the relative movement of the two elements. The invention is characterised in that the friction retaining means include: a friction member (105) solidly mounted on the first element in order to rub against the second element (102) on a friction surface that extends parallel to the sliding axis; a press member (107) for exerting a push force on the friction member, which pushes the friction member against the second element along an axis perpendicular to the relative movement of the elements; and means connecting the friction member to the first element (110, 111), which separate the friction member from the second element during the movement of the friction member relative to the first element.
L' invention concerne un dispositif à friction contrôlée, comportant un premier élément sur lequel un deuxième élément est monté pour coulisser selon une direction de coulissement (X), et des moyens de retenue à friction disposé pour exercer entre les deux éléments un effort résistant s'opposant au déplacement relatif des deux éléments, caractérisé en ce que les moyens de retenue à friction comportant : - un organe frotteur (105) monté solidaire du premier élément pour frotter sur le deuxième élément (102) selon une surface de frottement s'étendant parallèlement à la direction de coulissement; un organe presseur (107) pour exercer sur l'organe frotteur un effort de poussée de l'organe frotteur contre le deuxième élément selon une direction normale au déplacement relatif des éléments; - des moyens de liaison de l'organe frotteur au premier élément (110, 111) qui provoquent un décollement de l'organe frotteur du deuxième élément lors d'un déplacement de l'organe frotteur relativement au premier élément.
