89905 VEHICLE DOOR CHECK MECHANISM Abstract of the Disclosure A door check mechanism for regulating pivotal movement of a vehicle door between a closed position and one or more open positions, which mechanism is sometimes incorporated in a hinge, includes an elongated track member having a track surface with at Least one detent receptacle in that track surface; a detent roller engages the track surface in rolling pressure contact at least part of the time whenever the door moves between its open and closed positions. A second detent member may engage a second track surface on the track member; the second detent member may also be a roller. Either the detent roller or the track has a resilient elastomer core, preferably an elastomer material (e.g., a silicone polymer) that retains its elastic properties over a temperature range that extends much higher than any temperature usually endurable by humans; the core is usually covered by a hard, relatively non-elastic but flexible sheath. The engaging portions of the roller and track surfaces are preferably dissimilar materials, usually a metal and a resin.
