ABSTRACT:
System for controlling selective relative positional movement of portions of a bed structure with respect to a main supporting bed base frame, such as in a hospital bed, in which a single common motor controllable, e.g. by suitably actuatable switch means, for driving operation selectively in alternative forward and reverse directions is utilized, and which contemplates a plurality of independently operable individual motion transmission means connectable to such bed structure portions for correspondingly effecting the selective relative positional movement thereof with respect to the main supporting bed base frame, e.g. for head, knee and high-low adjustments of the bed, plus common drive transmission means connected to the common motor for corresponding operation thereby in such directions for driving in turn the motion transmission means, coupling means actuatable for operatively coupling and uncoupling the individual motion transmission means with the common drive transmission means, and common uniselective control means operatively connected to the coupling means for uniselectively actuating the coupling means for coupling the common drive transmission means with a selective individual motion transmission means and for simultaneously preventing the coupling of the common drive transmission means with the remaining corresponding motion transmission means, whereby to control such selective relative positional movement, preferably with remote override control means arranged operatively for selectively preventing the actuating of the coupling means by the common uniselective control means and for independently selectively controlling the actuation of the coupling means.
