Abstract
Abstract A hospital bed which is adapted to be placed in either the Fowler or the Contour position is provided with a manually operated selector mechanism so that with one operation mechanism both the head and foot assembly or the head assembly alone may be elevated. The selector mechanism engages a mechanical linkage which transmits the elevation of the head section to the foot section.
