ABSTRACT:
A patient support is disclosed having a contoured upper body support with an integral lumbar support area. The lower body support is curved at the knee and likewise contoured for patient comfort. The upper body support is pivotally attached to the lower body support at a point simulating the pivotal location of the human hip. A drive linkage raises the toe area of the lower body support simultaneously with, but only for the initial reclining movement of the upper body support, maintaining the oral cavity in fixed relation to the head support. Arm supports are upwardly rotatable from a down, locked position to an up, unlocked position. The patient support has automatic recline and sit-up mechanisms with emergency stop circuitry.
