Transmission mechanism for use as connection of drive with lying surface of upper body support, has joints and guide elements, where displacement of lying surface is ensured, in which point of lying surface remains on constant height

摘要

The transmission mechanism has joints and guide elements, where a displacement of a lying surface (2) is ensured, in which an excellent point of the lying surface remains on constant height relative to a base surface. The transmission mechanism is connected with the lying surface by a joint connection, where the lying surface is rotationally displaced in right angle to the displacement by a drive opposite to the transmission mechanism and opposite to the base surface.
