Hinge for automotive vehicle doors

摘要

A hinge for vehicle doors includes: a first part fixable to a vehicle door and including an essentially vertical pin; a second part fixable to a frame of the vehicle and including an essentially cylindrical and vertical first cavity that houses the vertical pin; and a retaining device that retains infinite angular positions between the first and second parts. The retaining device includes: a sleeve surrounding the pin in the first cavity and an engagement member arranged between the pin and the sleeve. The engagement member couples the sleeve to the pin in any angular rest position of the hinge and automatically decouples the sleeve from the pin during relative rotation between the first and second parts. An interruption of the relative rotation between the first and second parts causes the engagement member to automatically couple the sleeve to the pin.
