Abstract:
1. A surgical armrest, comprising an arm support, a carrying structure for carrying said arm support, said carrying structure having a base and at least one pivot arm having a first end articulated on said base so as to pivot about an at least approximately horizontal pivot axis, and a second end connected to said arm support, such that a pivoting of said at least one pivot arm about said pivot axis causes a height adjustment of said arm support, and a control mechanism for controlling said at least one pivot arm for alternately permitting a fixing and a pivoting of said at least one pivot arm in downward direction and in upward direction, said control mechanism having at least one bar which is movable, at least in a longitudinal direction of said bar, upon pivoting of said at least one pivot arm, said control mechanism further having a freewheel coupling having a first coupling element and a second coupling element, said first coupling element being driven by said bar and being freely movable relative to said second coupling element upon an upward movement of said at least one pivot arm, and, upon a downward movement of said at least one pivot arm, driving said second coupling element, and said second coupling element being braked by means of at least one brake element.
