Abstract: A support device, suitable for the physically handicapped, and also for packaging delicate objects, consists of an airtight flexible bag filled with a granular material coated with an adhesive. A non-return valve is provided to allow a partial vacuum to be established within the bag. In use, the bag when non-evacuated of air, is pushed against a body to be supported so that the granular material flows and assumes a shape closely conforming to the body. Air is then evacuated from the bag and as a result the granular material is compressed into a rigid mass in the conformed shape. The mass is then made permanently rigid by activating the adhesive coating, for example with microwave radiation.

Abstract: A support device, for the physically handicapped is disclosed comprising a cruciform airtight bag of synthetic plastics material filled with a granular material, for use as a liner for a conventional chair. The bag can be deflated to lock the granular material into a rigid structure which supports comfortably a physically handicapped person sitting in the chair.
