ABSTRACT:
Pad assemblies are described having novel backing disks, a cushion layer in contact with a surface of the backing disk, and a skin covering the cushion and at least one surface to the backing disk. The novel backing disks have a flexible outer collar that in conjunction with the cushion provides support for the pad's sealing surface and maintains an even tension on the pad's skin. Preferred embodiments providing additional support for the pad's sealing surface further utilize a backing disk having an inner collar, coaxial to the flexible outer collar, and have a cushion extending between the collars and over the inner collar. As a result of the improved support, fewer tears in the pad's skin result from repeated contacts with the tone hole and from fluctuations in the skin's moisture content.
