ARTICULATING BED WITH SIMPLIFIED ACTUATION

摘要

An articulating bed incorporates an actuation system which employs an actuator pivotally attached at a first end to a midpoint of a head end rail of a frame. The actuator has a range of motion from a retracted position to an extended position. A roller assembly is pivotally attached to a central lateral rail in the frame and has a spacer bar. A second end of the actuator is pivotally attached to a midpoint of the spacer bar. The roller assembly further has rollers engaging a lower surface of an upper body support section. The upper body support section is substantially horizontal with the actuator in said retracted position and urged by the rollers for angular rotation about an axis through the range of motion for the actuator to a raised position in the extended position.
