Dust boot assembly with retaining ring, pivot joint assembly

摘要

The boot assembly used with the joint assembly has an elastic boot and annular retainer ring. The elastic boot is approximately cup-shaped, has an axis, and has a cavity along it. At the base of the boot a substantially coaxial first hole is drilled into the cavity. The retainer ring is substantially concentric with the first hole of the boot and secured to the boot at the base. The retainer ring has a plurality of radially inwardly extending fingers. Each finger has a finger hole through the finger that reduces the bending strength of the finger in response to the axial force against the bending strength of the finger.
