Plastic door check without steel fasteners

A door check device for installation between a vehicle body and a vehicle door that swings in opposing opening and closing directions relative to the vehicle body, the door check device comprising:

• a housing assembly, the housing assembly comprises:
• a first mounting structure constructed and arranged to be mounted on one of the vehicle body and the vehicle door;
• a biasing structure;
• a first link member engaging structure and a second link member engaging structure;
• and
• a plastic housing member containing the biasing structure, the first link member engaging structure and the second link member engaging structure therein, the plastic housing member having a first engagement structure;
• the first mounting structure including a plastic cover, the plastic cover having a second engagement structure that is constructed and arranged to engage with the first engagement structure to form an area of contact therebetween,
• wherein the plastic housing member and the plastic cover are secured by fusion of the materials to each other in the area of contact between the first and the second engagement structures;
• an elongated link member, the elongated link member extending through the housing assembly, the elongated link member comprises:
• a second mounting structure constructed and arranged to be mounted on the other of the vehicle body and the vehicle door;
• and
• detents that extend generally in a transverse direction of the elongated link member on opposing face surfaces thereof;
• wherein, when the door check device is installed and the vehicle door is swung in the opposing opening and closing directions thereof relative to the vehicle body, the elongated link member and the housing assembly are configured to move relative to each other with the first and the second link member engaging structures travelling along the opposing face surfaces of the elongated link member;
• and
• wherein, when the door check device is installed and the vehicle door is swung in the opposing opening and closing directions thereof relative to the vehicle body, the biasing structure is configured to bias the first and the second link member engaging structures relatively towards one another to thereby urge the first and the second link member engaging structures into engagement with the opposing face surfaces of the elongated link member;
• and
• wherein, when the door check device is installed and the vehicle door is swung to a location with respect to the vehicle body, the first and the second link member engaging structures cooperate with the detents on the opposing face surfaces of the elongated link member so as to maintain the vehicle door at that position until a force is applied to the vehicle door that is sufficient to cause the elongated link member and the housing assembly to move relative to each other so as to urge the first and the second link member engaging structures relatively apart from one another and out of cooperation with the detents on the opposing face surfaces of the elongated link member against the biasing of the biasing structure.
