Seal assembly for a bicycle bottom bracket
First Claim
1. A seal assembly dimensioned to fit within an adapter member for a bicycle bottom bracket containing an axle, wherein the seal assembly comprises:
- a support that includes a laterally inwardly facing surface, a laterally outwardly facing surface, a radially inner portion and a radially outer portion, wherein the laterally inwardly facing surface faces laterally inwardly relative to the bicycle when the seal assembly is mounted to the bicycle;
an outer seal extending circumferentially around a radially outer surface of the support to prevent contaminants from entering past the outer seal into the adapter member;
an inner seal extending circumferentially around a radially inner surface of the support to prevent contaminants from entering past the inner seal into the adapter member;
wherein the outer seal and the inner seal are disposed on opposite lateral sides of the support; and
wherein the support is dimensioned so that a space is formed between the radially outer portion of the support and an inner peripheral surface of the adapter member when the seal assembly is mounted to the bicycle so that the radially outer portion of the support faces the inner peripheral surface of the adapter member across the space.

Abstract
A seal assembly includes a support, an outer seal extending circumferentially around a radially outer surface of the support, and an inner seal extending circumferentially around a radially inner surface of the support. In a more specific embodiment, the support comprises an annular base member, an inner ledge extending from a radially inner side of the base member, and an outer ledge extending from a radially outer side of the base member. The inner seal is disposed at a radially inner edge of the base member opposite the inner tubular member, and the outer seal is disposed around an outer peripheral surface of the outer tubular member.
