ABSTRACT:
The invention relates to a surgical armrest, comprising an arm support and a carrying structure for the arm support. The carrying structure has a base and at least one pivot arm which at one end is articulated on the base so as to pivot about an at least approximately horizontal pivot axis and at the other end is connected to the arm support, such that a pivoting of the at least one pivot arm about the pivot axis causes a height adjustment of the arm support. The at least one pivot arm is assigned a control mechanism which alternately permits a fixing and pivoting of the at least one pivot arm in the downward direction and in the upward direction. The control mechanism has at least one bar which is movable, at least in its longitudinal direction, upon pivoting of the at least one pivot arm. The bar interacts with a freewheel coupling comprising a first coupling element and a second coupling element, wherein the first coupling element is driven by the bar and is freely movable relative to the second coupling element upon an upward movement of the at least one pivot arm, and, upon a downward movement of the at least one pivot arm, drives the second coupling element along with it, the second coupling element being braked by means of at least one brake element.
