Abstract: A door check mechanism which provides infinite stable retaining positions for a motor vehicle includes an articulated guided arm mounted to one of the vehicle body or the door and a mechanism mounted on the other of the vehicle body or the door such that the guiding arm penetrates the mechanism with a relative displacement between the two parts. A wedging function results from a blocking of the guiding arm by the mechanism. The mechanism includes a carriage device with a braking roller held in contact with the guiding arm and a braking element to ensure the wedging function. When a load greater than a predetermined value is exerted on the door, an axle of the roller slides along lateral guiding slots until the roller is released from the braking element, thus allowing free rotation of the roller and releases the mechanism.

Abstract: The present invention relates to a door check mechanism providing infinite stable positions with applications more specifically in the area of motor vehicles, comprising on the one hand an articulated guiding arm (1), mounted to the vehicle body or to the door, and on the other hand a mechanism (9), mounted to the other part, either the door or the vehicle body, in such a way that guiding arm (1) penetrates through mechanism (9) with a relative displacement between these two parts, the wedging function resulting from a blocking of guiding arm (1) by mechanism (9). Mechanism (9) comprises a carriage device (2), including 2 braking-rollers (21) and (22), held against each other as well as against guiding arm (1), in order to ensure the wedging function.
