<p>A chair arm-rest comprises a rear portion (3) secured to the supporting structure (2) of the arm-rest, and a front portion (4) which is pivotally mounted to the rear portion (3) around an axis substantially parallel to the longitudinal direction of the arm-rest and adapted to assume two different operative positions which are spaced from each other by about 180 DEG . The articulation axis (5) is offset towards one side of the rear portion (3) of the arm-rest, so that in one of said two operative positions the front portion projects towards the inner side of the arm-rest with respect to the rear portion (3), so as to provide adequate support for the arm of the occupant when the latter must perform an operation at the keyboard of a typewriter or a computer. <IMAGE></p> |
