A soft compliant substantially platelike foam cushion is bonded to a substantially rigid backing plate and the periphery of the cushion has an integrally coated compliant membrane. When an axial or oblique force is applied to the backing plate surface remote from the cushion, the cushion and membrane compress, yielding extraordinary traction properties. | |
