A flexible seal assembly has an elastomeric body with a convoluted intermediate portion for accommodating pivotal movement about the center of a spherical joint and an integral radial seal lip for accommodating rotational movement about a central axis of the joint. The seal lip extends from an inner diameter portion of elastomeric body in proximate relationship to a rigid plastic lip restraining ring which is molded into such inner diameter portion such that flexure loads are carried by the restraining ring and have no effect on the seal lip.
1. In a flexible seal assembly for use in sealing a spherical joint, said flexible seal assembly having an outer mounting ring, an inner lip restraining ring, and an elastomeric body, said body having an outer diameter portion secured to said mounting ring, an inner diameter portion secured to said lip restraining ring and a thin walled convoluted intermediate portion having a generally S-shaped configuration interconnecting said outer and inner diameter portions and providing sufficient flexure capability for accommodating pivotal movement of said spher...
