Patent ID: 8662594

Claim:
An arm rest, adjustable in inclination, in particular for vehicles, comprising: a fixed part, intended to be connected to the frame of the vehicle; a movable part, hinged to said fixed part around a rotation axis X by a shaft aligned along said axis X to move between a lowered angular position and a raised angular position, and a system for adjusting the inclination of said movable part between said lowered position and said raised position; wherein said system for adjusting the inclination α comprises: at least one freewheeling bearing, chosen from those of rolling-contact type and those of cam type, associated to said shaft so as to allow said movable part to rotate around said axis X only in the direction of rotation which from said lowered position leads to said raised position; and releasing means, acting on said shaft and able to liberate the rotation of said movable part from said raised position to said lowered position, wherein said freewheeling bearing is joined to said fixed part and wherein said shaft is joined to said movable part and is connected in rotation to said freewheeling bearing inside a bush so as to be able to rotate freely around said axis X, said releasing means being able to alternately take a first operative position, in which they make said shaft rotate around said axis X together with said bush and a second operative position, in which they let said shaft free to rotate around said axis X.
