ABSTRACT:
An electrically operable hospital bed having a main frame, an articulated mattress support frame including head and thigh sections movable to various positions of inclination with respect to the main frame, an operating mechanism for elevating the head section, and an automatic contouring mechanism including linkage interposed between the thigh section and main frame selectively actuable to move in response to elevation of said head section to support and progressively elevate the thigh section. The mechanism may be deactivated to permit elevation of the head section without elevation of the thigh section.
Manual thigh section elevation means are provided with capabilities for further elevation of the thigh section without affecting the automatic mechanism or for operation of the thigh section independently of movement of the head section.
