Abstract
A plastic cushion pad (40) includes at least one plastic spring portion (46) between oppositely facing contact surfaces (42, 44). In one example, the pad (40) is vacuum formed using a film of carbon-impregnated polystyrene material. The plastic spring portion (46) is configured to provide the desired amount of resiliency or cushion provided by the pad responsive to a compressive force. In one example, the plastic spring portion is designed to prevent any lateral deformation of the pad when a compressive force is applied.
