A seal member (110) for a joint between a pivot member (114) movable about a rotational axis (RA) of a shaft (112) includes a ring (130), a flange (132), and a resiliently flexible intermediate portion (134) interposed therebetween. The ring (130) includes annular distal and proximal ring faces (210, 212) disposed in spaced relationship to each other along a longitudinal axis (LA). The flange (132) includes a pair of flange faces (230, 231) disposed in spaced relationship to each other along the longitudinal axis (LA). The flange (132) includes outer and inner flange surfaces (233, 237) extending along the longitudinal axis (LA) between the pair of flange faces (230, 231) at, respectively, outer and inner flange perimeters (235, 238) thereof. The intermediate portion (134) is connected to the proximal ring face (212) of the ring (130) and to the inner circumferential flange surface (237) of the flange (132) such that the ring (130) is relatively movable with respect to the flange (132). |
