ABSTRACT:
Multiconvoluted boot seal for universal joints and other mechanisms in which convolution side walls have radial ribs formed therein to strengthen the walls to reduce wrinkling and resultant cracking at high joint angles. The ribs on one side wall are external at high joint angles and mesh with rib spaces formed by internal ribs on an adjacent side wall. This meshing reduces relative turning movement between the side walls so that abrasion and boot seal wear is reduced.
