Patent ID: 8668112

Claim:
A cover for sealing a hole in a part of a vehicle suspension assembly, the cover comprising: a main body configured to be inserted into the hole in an insertion direction, the main body including a substantially rectangular and flat top wall on an inserted end in the insertion direction, and a vertical side wall, the top wall and side wall partially defining a unitary interior space with an open side in a second direction opposite to the insertion direction and configured to receive a moving member of the assembly; a flange extending outwardly horizontally from the main body around the open side, the flange configured to engage an edge of the hole to seal the assembly against the accumulation of dirt and other foreign material within the main body; an elastically deformable linear hinge formed on the exterior of the main body, the hinge comprising a concave ridge extending along a long axis of the top wall of the main body and projecting away from the open side of the main body and open into the unitary space, the hinge allowing the main body to be compressed in a width direction transverse to the hinge so that the width of the main body in the direction perpendicular to the hinge is decreased when the cover is subjected to a compressing force, the body returning to its original width in the direction perpendicular to the hinge when the compression force is removed and resuming its pressure against the flange to maintain the seal on the cover.
