Abstract: Vehicle door check device comprising: a longitudinal tie (14) provided on its outer surface with at least one retention seat (16), a holder (12) with a passage (28) through which the tie (14) can slide, a plurality of retention bodies (40) supported by the holder and engaging in the said one or more retention seats so as to define at least one stable retention position, and elastic means (34) acting between the said retention bodies (40) and the said holder (12) so as to push the retention bodies (40) against the tie (14). The tie (14) has a circular cross section and the retention bodies (40) act along radial directions with respect to the axis of the tie (14).

Abstract: A door-stop device for vehicles having a base structure with a pair of rollers that are parallel to each other and pushed against one another. The door-stop device also includes a metal tie rod with a pair of rolling surfaces set opposite to one another where the rollers act. The rolling surfaces have a positioning notch designed to engage one of the rollers and define a position of stable retention of the door. The positioning notch includes an arched central portion with an extension extending in the direction of the longitudinal axis of the tie rod and a pair of arched lateral portions with a radius of curvature.

Abstract: A hinge for vehicle doors having a first hinge element (14), a hinge pin (18) rotatably carried by the first hinge element (14) and a second hinge element (16) removably attached to the hinge pin (18). The hinge further includes a retention device (12) including a plurality of rolling members connected in rotation to the pin (18) and cooperating with elastic structure (54) which tends to force the rolling members (38) to engage with a rolling race. The rolling members are balls (38) connected in rotation to the pin (18) via a guiding plate (40) provided with positioning seats (42) for the balls (38).
