The inclined portion supports the femurs of a person so that the femurs and knees are supported in a position below the person's acetabulum, the horizontal portion receives and holds the ischial bones and the inclined portion supports a person's gluteal muscles and sacro-illiac ligaments. The seat has a backrest to support a person between the second and third lumbar vertebrae when a person is seated on the apparatus. The backrest has a support surface which is positioned between the rear of the seat and the first intermediate positions so that the person's gluteal muscles can extend behind the support surface between the rear of the seat portion and the support surface of the backrest.

Abstract: A cushion that includes a cushioning element. The cushioning element has a number of substantially parallel elongate columns formed in a gelatinous cushioning media. The columns are configured so that when a force is applied to the cushioning element in a direction that is generally parallel to the longitudinal axes of the columns, the cushioning element will yield by a combination of compressability of the cushioning media and bucklability of the walls of the columns. In particular, the walls of columns which are located beneath a protruberance on an object being cushioned tend to buckle, permitting the cushioning element to conform to the shape of the cushioned object while evenly distributing a supporting force across the contact area of the cushioned object and avoiding pressure peaks. The preferred cushioning media is a gelatinous elastomer or gelatinous viscoelastomer. Various configurations of cushioning elements, including sidewall supports, are disclosed.

Abstract: The present invention relates to a tailbone cushion to eliminate discomfort of patients afflicted with hemorrhoids, fissure, damaged coccyges (tailbone) or the like associated with sitting on hard surfaces. The tail bone cushion of the present invention consists of a cushion section having front, rear and side edges and generally flat top and bottom surfaces. The cushion section has a cutout centrally disposed in the rear edge providing said cushion section with a U-shaped configuration. The cutout is sized and located to eliminate contact between the patient's tailbone and either the cushion or the surface underneath the cushion. The cushion section is preferably tapered in thickness and firmness from rear to front. The cushion section is also preferably formed from a casing filled with a material that has low compression under a patient's body weight yet soft enough to permit sitting for extended periods with minimal discomfort. The tail bone cushion is optionally provided with a back support.

Abstract: Seating cushion assembly (10) for use with a wheelchair having a seat base (20). A flexible foam cushion (30) is mounted on base (20) with at least one insert member (40) removably positioned at a support location (33) between the foam cushion (30) and the base (20) to upwardly or outwardly raise a top surface (5) of the foam cushion (30) at the support location (33). The resulting lateral support contour (35) in the top surface (5) of the cushion assembly provides user stability and pressure distribution while seated on the seating assembly (10) and yet the user can selectively eliminate or remove the contours (35) by removing the contour-forming inserts (40). The foam cushion (30) further has sufficient thickness and resiliency to permit the user to temporarily sit directly over the contour-forming insert member (40) during use of the cushion assembly (10), which enables safe use of the entire area of the wheelchair cushion assembly (10).

Abstract: An extendable and collapsible upholstered seat cushion is manufactured from a unitary piece of foam. The upholstery material is integrally molded with the foam cushion. Channels are molded into the foam perpendicular to the length of the seat to allow for compression of the overall length of the seat cushion. Further, channels may be molded into the foam in a direction parallel to the length of the seat cushion to allow for compression of the seat cushion in the lateral direction as well. The channels have angular recesses near the surface of the cushion to provide a home for compression hinges created by connective foam and cloth disposed between segments of the cushion. A telescoping support frame is provided to assist in the compression and extending of the seat cushion. This support frame may be telescoped manually or with assistance by power.

Abstract: When in use on a chair, sets of strings which extend from the seam proximate an expandable pocket are tied around vertical elements of the chair back to secure the cushion. The strings are stored within the pocket when the product is used as a decorative pillow. The pocket material matches the material of the side wall and may be similarly pleated, so as to be visually unobtrusive. The product saves space and money because it can be used as a decorative pillow or a seat cushion, as needed.
