ABSTRACT:
A device that can be attached to any existing reclining type device such as chairs and beds that will eliminate shear forces on the user's body regardless of the level of movement. The primary components of the device are a seat plate, a seat slide plate, a back plate and a back slide plate. The back slide plate is pivotally attached to the seat plate. The seat slide plate is pivotally attached to the back plate. Pivoting the back plate with respect to the seat plate engages the pivotally attached seat slide plate and the pivotally attached back slide plate toward or away from each other depending on the starting position. The engagement of the slide plates mirrors the movement of the occupant in both the recline to horizontal position or the return to upright to vertical position.
