Abstract
The present invention is directed to a custom-contoured cushion for a wheelchair or other seating device and a method of making the same. In one embodiment, the novel custom-contoured cushion is comprised of a stretchable bag filled with soft and resilient closed-cell foam pellets adhered together by and/or embedded within an elastomeric polymerizable adhesive. The pellets do not absorb a significant amount of the adhesive and, after molding, remain sufficiently soft and resilient to provide a comfortable and durable cushion. Alternatively, the cushion contains soft and resilient pellets, but does not contain the elastomeric polymerizable adhesive. In the first embodiment, the custom-molded, custom-contoured cushion is made by mixing the pellets with the adhesive to form a pellet/adhesive mixture, positioning the user on a bag filled with the pellet/adhesive mixture, molding the mixture around the user to provide cushioning around the user's seating surface, and allowing the adhesive to cure. The pellets and adhesive may either be added to the bag separately and mixed within the has, or may be mixed outside the bag, after which the pellet/adhesive mixture is added to the bag.
