Rollerless door check mechanism
First Claim
1. A check mechanism for a frame and a closure movable relative to the frame, said check mechanism comprising, in combination:
- a housing securable to one of the frame and the closure and having an opening;
a check arm securable to the other one of the frame and the closure and extending into the opening;
at least one guide within the housing and engaging the check arm;
at least one spring member biasing the at least one guide toward the check arm;
wherein the at least one guide and the check arm are adapted to resist movement of the closure relative to the frame when the at least one guide engages predetermined locations of the check arm and are adapted to provide sliding contact therebetween upon movement of the closure relative to the frame; and
wherein the at least one guide has a generally V-shaped portion, in cross-section, engaging a camming surface forming the predetermined locations such that movement of the closure relative to the frame is resisted when the generally V-shaped portion engages the predetermined locations.

Abstract
A check mechanism for a motor vehicle door includes a housing secured to either the vehicle frame or the door and a check arm secured to the other one of the vehicle frame and the door. The door check extends into the housing through an opening in the housing. A pair of opposed guides are located within the housing and engage opposite sides of the check arm. Each guide has a generally V-shaped portion, in cross-section, engaging the check arm to generally form a line contact between the guide and the check arm. Spring members such as elastomeric springs bias the guides toward each other and the check arm. The guides and the check arm are adapted to resist movement of the closure relative to the vehicle frame when the guide engages predetermined locations of the check arm. When the door is moved relative to the frame, the guides slide along the exterior surface of the check arm. Preferably, the check arm has a covering of plastic material and each guide has a contact portion comprising a low friction material such as polytetrafluoroethylene.
