Patent number: 8011043Abstract: A cushion 302 comprising a molded foam base 302 with an array of individual suspension elements 306 at the ischial area of the cushion. In one aspect the array of suspension elements is in a recess 307 in the top of the base and in another aspect the array of suspension elements is in an inner cavity 406 defined by the base. The suspension elements are arranged in a pattern wherein the longitudinal axis of each suspension element in the array is positioned at a right angle or parallel to the longitudinal axes of the adjacent suspension elements. Each suspension element has a displaceable load-bearing surface 14, a first end wall 20, a second end wall 22, and an optional bottom wall 30, with load-bearing surface and recited walls defining an inner chamber. The material thickness of the load-bearing surface generally is greater than the material thickness of the end walls whereby the end walls deflect outwardly toward the load-bearing surfaces of adjacent support elements under load.Type: GrantFiled: May 18, 2009Date of Patent: September 6, 2011Assignee: Roho, Inc.Inventors: Robert H. Graebe, Dennis L. Clapper

Patent number: 7681264Abstract: A cushion comprising an array of individual suspension elements arranged in a pattern wherein one embodiment the longitudinal axis of each suspension element in the array is positioned at a right angle or parallel to the longitudinal axes of the adjacent suspension elements. Each suspension element has a displaceable load-bearing surface, a first end wall, a second end wall, and an optional bottom wall, with load-bearing surface and recited walls defining an inner chamber. The material thickness of the load-bearing surface generally is greater than the material thickness of the end walls whereby the end walls deflect outwardly toward the load-bearing surfaces of adjacent support elements under load. The load-bearing surface can have a substantially arch-shaped, elliptical or rectangular cross-section and may be constructed from different materials to make a composite suspension element.Type: GrantFiled: July 22, 2008Date of Patent: March 23, 2010Assignee: ROHO, Inc.Inventor: Robert H.

Patent number: 6161238Abstract: A cushion comprising an orthotic base which has a flexible body of sufficient strength to support a user while conforming to the buttocks and legs of the user and pillars on the bottom of the base to support the same and being of desired height and positioning to position the user in a desired position. The disclosure shows a preferred composite cushion comprising the orthotic base; a foam top on the base with a T-shaped cutout at the rear to accommodate an air cell pad; a balance foam underpad of smaller front to rear measurement than the base and movable from the front to the rear of the base to incline the user in a desired front to rear positioning and from left to right to position the user in a left to right direction; and a cover enclosing the base, the foam top, the air cell pad and the underpad. Removable support members are attached to the pillars beneath the orthotic base at predetermined locations to shape the top surface when a load is applied.Type: GrantFiled: August 21, 1998Date of Patent: December 19, 2000Inventor: Robert H.

Patent number: 5640728Abstract: A support system (A) including a cushion (B) for uniformly distributing the weight of an individual uniformly and further circulating air along the individual's body. The cushion (B) has porosity and air cells (4) which project upwardly from the base (2) and are in communication through the base (2) so that all exist at the same air pressure. The base (2) has apertures (14) between the cells (4). The system includes a distributor (20) beneath the cushion base (2) and a duct (30) which connects to one side of the distributor (20). The distributor (20) has a plurality of blunted pillars (24) which support the cushion (B) above the distributor base (22) and create a distribution and access chamber (F) beneath the cushion base (2). The duct (30) can have a vertical section (34,40) connected to a container (42) for collecting liquids. A blower (D) discharges conditioned air into the distribution chamber (20) through the duct (30).Type: GrantFiled: November 20, 1995Date of Patent: June 24, 1997Inventor: Robert H. Graebe

Patent number: 5613257Abstract: A modular cushion comprising a shaped base which has a flat rear portion having a substantially flat center area and a raised front portion with angularly directed valleys on each side, a removable pommel releasably secured to the flat center portion, a resilient pad positioned on the flat portion of the base to relieve pressure on the ischial and trochanters and a cover having a non-skid undersurface and two-way stretchable material covering a portion of the top. The resilient pad preferably has an array of upstanding interconnected inflatable cells. The base is of porous cellular material and has a water impervious separate integral skin adhered over the top surface for strength and protection.Type: GrantFiled: November 4, 1994Date of Patent: March 25, 1997Inventor: Robert H. Graebe

Patent number: 5596781Abstract: A vacuum or heat formed cushion having upstanding cells of thin (15-40 mil) wall thickness and having rectangular body sections with upwardly inclined (10.degree.-40.degree.) triangular top panels. The cushions can be attached together to form a mattress or used individually as a wheelchair or other chair or back cushion. The cells of the cushion can all be interconnected or the cushion can be divided in two or more independently inflated compartments. A special wheelchair cushion has cells of different shapes, sizes and heights to promote positioning of a user on a wheelchair.The cushion has openings through the base to allow it to be placed on a manifold so that body fluids can drain away from the patient and conditioned air can be supplied to the patient.The top surfaces of the cells are textured to prevent sealing off the pores of the user's skin.Type: GrantFiled: October 20, 1995Date of Patent: January 28, 1997Assignee: Crown Therapeutics, Inc.Inventor: Robert H. Graebe
