An electric power driven wheelchair has at its left-hand side a conventional desk arm rest 1 and at its right-hand side an arm rest 2 including a supporting frame 3, a padded, elongate top part 5 slidable longitudinally relative to the frame 3 and a manually operable control device 6 for the power drive. A spring urges the part 5 forwards into a front end position. If the chair is driven forwards into a desk or table top, the part 5 ist pushed rearwards by the desk or table top against the action of the spring until, when the part 5 nears its rearward end position 5 min , it operates a limit switch to open the power drive circuit. |
