Abstract

L'invention concerne un fourreau (103) d’une colonne de direction comportant deux éléments constitués par un tube extérieur (101) et un tube intérieur (102), et un système de réglage (100) d’un effort résistant s’opposant à un mouvement relatif de translation entre les deux éléments (101, 102), le système de réglage (100) comportant : au moins un patin de friction (20), supporté par un premier (101) des deux éléments (101, 102) ; une surface de serrage (30) solidaire d’un deuxième (102) des deux éléments (101, 102), le patin de friction (20) étant configuré pour être en contact et en appui contre la surface de serrage (30) ; un mécanisme de réglage (10) comportant une came (11) en appui direct ou indirect sur un appui pour générer une variation de pression du patin de friction (20) par rapport à la surface de serrage (30) parallèlement à un axe de référence (X) fixe par rapport au premier (101) des deux éléments (101, 102), de sorte à faire varier l’effort de pression du patin de friction (20) contre la surface de serrage (30) du deuxième (102) des deux éléments (101, 102), entre : une position d’utilisation et une position de réglage, le fourreau de la colonne de direction (103) étant caractérisé en ce que le mécanisme de réglage (10) du système de réglage (100) est configuré pour engendrer un mouvement de rotation relative entre la came (11) et l’appui (12) autour de l’axe de référence (X). (Fig. 8)The invention relates to a sleeve (103) for a steering column comprising two elements consisting of an outer tube (101) and an inner tube (102), and a system (100) for adjusting an opposing resisting force. to a relative translational movement between the two elements (101, 102), the adjustment system (100) comprising: at least one friction pad (20), supported by a first (101) of the two elements (101, 102) ; a clamping surface (30) integral with a second (102) of the two elements (101, 102), the friction pad (20) being configured to be in contact and in abutment against the clamping surface (30); an adjustment mechanism (10) comprising a cam (11) bearing directly or indirectly on a support to generate a pressure variation of the friction pad (20) relative to the clamping surface (30) parallel to a reference axis (X) fixed with respect to the first (101) of the two elements (101, 102), so as to vary the pressure force of the friction pad (20) against the clamping surface (30) of the second (102) of the two elements (101, 102), between: a position of use and an adjustment position, the sleeve of the steering column (103) being characterized in that the adjustment mechanism (10) of the adjustment system (100 ) is configured to generate a relative rotational movement between the cam (11) and the support (12) around the reference axis (X). (Fig. 8)
