  • Patent number: 5152030
    Abstract: A door check for controlling pivotal movement of a vehicle door between a closed position and one or more open positions, sometimes incorporated in a hinge, includes a rigid, elongated track member having two opposed track surfaces with at least one detent receptacle in one track surface or in both track surfaces. A roller detent member engages one 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, comprising a sliding, self-aligning, non-rotational bearing, engages the other track surface. Both detent members are formed of a fiber reinforced resin, such as a glass fiber reinforced nylon. The second detent member is urged toward one track surface by an elastomer pad, preferably an elastomer such as a silicone polymer that retains its elastic properties over a wide temperature range that extends beyond the temperatures of manufacturing processes or human environments.
