CA 2122910

There is disclosed a friction hinge assembly capable of providing hinged motion of two elements (1, 3) with a programmable frictional torque. The frictional torque can be made to vary with the angular orientation of the two hinged elements. The frictional hinge assembly is comprised of a band (17) wrapped around a pintle (5) which is constrained to move rotationally with the first hinged element. One end of the band has a lug (19) configured to press against the second hinged element, exerting there-upon a torque about the pintle. The other end of the band has a tail (25) to which is applied a controlled force to produce the desired frictional torque between the band and the pintle.

Assemblage d'articulation à frottement capable d'assurer le mouvement articulé de deux éléments (1, 3) avec un couple de frottement programmable. On peut faire varier le couple de frottement en fonction de l'orientation angulaire des deux éléments articulés. L'assemblage d'articulation à frottement est constitué d'une bande (17) enveloppant un pivot (5) qui est forcé de se déplacer en rotation avec le premier élément articulé. Une extrémité de la bande a un bossage (19) configuré pour appuyer contre le deuxième élément articulé, y exerçant un couple autour du pivot. L'autre extrémité de la bande a une queue (25) sur laquelle s'applique une force contrôlée de manière à produire le couple de frottement souhaité entre la bande et le pivot.
