ABSTRACT:
A frame for an adjustable bed is disclosed and which comprises a body supporting platform composed of a head panel, a center panel, a leg panel, and a foot panel. A base supports the platform, and the base includes a pair of upwardly inclined guide surfaces which are in the form of an inverted V. A U-shaped lift arm is pivotally connected to the head panel and slides along one of the guide surfaces to raise and lower the head panel, and a second U-shaped lift arm is pivotally connected to the leg panel and slides along the other of the guide surfaces to raise and lower the leg panel. A pair of electrical drive motors are provided for separately controlling the sliding movement of each of the lift arms in both directions.
