ABSTRACT:
Different hospital bed adjustments (such as high-low, back and knee adjustments) may be made simultaneously with a transmission that transmits power from a single rotating drive to selected ones of a series of independently rotatable output shafts or drive screws, each of which controls a different bed adjustment. Each of the drive screws may be individually clutched to the rotating drive independently of the other drive screws. With this arrangement, a plurality of drive screws may be clutched at the same time in order to effect concurrent operation of a plurality of adjustment mechanisms thereby obtaining rapid re-positioning of the hospital bed to a new position.
