Patent ID: 8893368

Claim:
A pivot joint assembly comprising: a first part with first and second side walls and a hole passing through the first part between the side walls, the exterior of the hole being defined by a bore wall; a pivot pin passing through the hole, the pivot pin defining a pivot axis; a second part which is carried by the pivot pin wherein the first or second part can rotate relative to the other part about the pivot axis; a bush comprising an annular sleeve with an inner face which engages the pivot pin and an outer face which engages the bore wall of the first part; and a sealing ring for preventing the ingress of contaminants between the bush and the first part, wherein the sealing ring has a body which is attached to the first side wall of the first part, and a sealing member which extends away from the body in a radial direction towards the pivot axis to a sealing lip which engages the bush without being attached to it, and wherein the sealing member is in a state of resilient compression so that it urges the sealing lip towards the bush and can expand away from the body in the radial direction to maintain engagement with the bush in the event that the bush moves away from the body in the radial direction.
