Mounting for hinge arms of wings, especially of four-bar coupling mechanisms for the pivotable fastening of covering hoods

The invention relates to a mounting for hinge arms of wings, especially of four-bar coupling mechanisms for the pivotable fastening of covering hoods to vehicle bodies, the hinge arms having bearing lugs at the ends and being rotatably mounted on bearing bushes passing through these, by means of supporting pins arranged especially on the vehicle and on the corresponding covering hood respectively, and the bearing bushes being guided axially by means of a two-part holding element which can be fixed to the respective supporting pin and engages over the edges of the bearing lug on both sides and which consists of two flanged sleeves. At least the supporting pins located on the covering hood are mounted on both sides in vertically arranged long holes of an essentially U-shaped profile, a locating shank of the supporting pin passing positively through the bores of the flanged sleeves, in such a way that, by bracing the supporting pin in the long hole by means of a nut, a fixing between the flanged sleeves and at the same time between their flange and the profile takes place as a result of a frictional connection on the end faces.
