ABSTRACT:
A drive unit for adjustable beds of the type which have movable head and leg sections, and adjustable height, comprises a unidirectional, rotary motor, and a drive shaft for each adjustable bed function. The driveshafts are selectively rotated in opposite directions by the motor. A pair of solenoids operably couple the motor with the driveshafts, interchangeably, or alternatively with a linear tracking gear, and thereby adjust the configuration of the bed.
