ABSTRACT:
A vehicular arm rest has a fixed axle carrying primary and secondary parts formed with meshing arrays of sawteeth angled to inhibit movement of the arm-rest body in a downward direction between a raised position and the lowered position but permit movement of the arm-rest body in the upward direction between the lowered position to the raised position. A spring braced between an abutment and the secondary part urging the secondary-part teeth into mesh with the primary-part teeth. Cam formations push the secondary part away from the primary part on pivoting of the primary part in the downward direction from the raised position of the arm-rest body toward the lowered position for decoupling the primary-part teeth from the secondary-part teeth and couple the primary-part teeth with the secondary-part teeth and prevent further movement in the downward direction on reaching the lowered position.
