ABSTRACT:
A wrist support gel cushion having a fabric upper surface and an adhesive gel lower surface, and a method of manufacturing same, in accordance with the present invention generally includes the steps of coating one side of a stretchable fabric with a thermoplastic gel, placing the coated fabric on a mold adapted for vacuum forming, applying a vacuum between the coated fabric and the mold, injecting an additional volume of the thermoplastic gel onto an exposed fabric surface during the vacuum forming, allowing the gel to set and solidify and removing the solidified gel having the fabric fixed thereto in order to obtain the wrist support gel cushion. The method may also include the step of depositing air filled bags or balloons on the coated fabric prior to injecting the additional gel in order to make a gel cushion having voids therein. The voids enhance the ability of the gel cushion to adhere to surfaces disposed at sharp angles to one another.
