The arm support (7) can be rotated around a joint (2), and incorporates a plate-shaped connecting component (10) with two diagonally positioned fixture lugs (18, 19), each with a joint (11, 12) connected to a fixture (7) via links (3, 4). - The fixture comprises a shaft around which the links are articulated, and each link has a longitudinal track (8, 9) through which a lock device (6) is fitted. The support can be moved upwards, forwards and backwards. |
