Abstract
Abstract An improved bicycle seat comprising a rigid shell supporting a foam layer having a pad of thermoplastic elastomer honeycomb either bonded thereto or embedded within said foam. A durable skin covers the shell, foam and padding layers. In an alternative embodiment, the foam, padding and covering skin are combined in a seat cover to be used over a standard bicycle seat.

Claim 1
Independent Claim
201 words
An improved bicycle seat comprising: a rigid shell having means for affixing the shell to a bicycle, said shell having a rear portion and a front portion, said rear portion being wider than said front portion; a layer of resilient foam disposed atop said rigid shell and having an outline substantially similar to that of said rigid shell; a honeycomb pad affixed to said resilient foam having a core made from strips of material bonded together to form the walls of a honeycomb-like network of generally hexagonally shaped cells, the walls of said cells each having upper edges and lower edges; a first sheet of resilient facing material thermal compression bonded to one surface of said core formed by said upper and lower edges, to form a body of singly faced core material; a second sheet of resilient facing material thermal compression bonded to the unfaced surface of said core to form a body of doubly faced core material wherein air is encapsulated within each of said cells; and wherein one of said sheets of facing material has a plurality of holes formed therein, said holes being disposed proximate the center of each of said air-filled cells to ventilate said padding.

Claim 3
Dependent Claim
178 words
A multilayer padded bicycle seat cover for use with a standard bicycle seat to cushion a rider's body, comprising: a layer of thermoplastic elastomeric honeycomb-structured padding made from strips of material bonded together to form the walls of a honeycomb-like network of generally hexagonally shaped cells, the walls of said cells each having upper edges and lower edges, said padding being disposed atop a foam layer; a sheet of durable material encapsulating said foam layer and said honeycomb padding, and having means for securely attaching said seat cover to said bicycle seat; a first sheet of resilient facing material, thermal compression bonded to one of said edges of said cells to form a body of singly faced core material; a second sheet of resilient facing material, thermal compression bonded to the unfaced edge of said cells to form a body of doubly faced core material; and wherein one of said sheets of facing material has a plurality of holes, said holes being disposed proximate the center of each of said air-filled cells, whereby said padding is thus ventilated.
