Arrangement For Assembling Two Parts By Screw-Fastening Using a Screw-Nut System

An arrangement (10) for assembling two parts (12, 14) by screw-fastening using a screw-nut system (16, 18, 24), characterized in that it comprises:

• a first vertical planar part (12) of generally longitudinal orientation comprising a housing (44) that extends axially along a screw-fastening axis in the vertical of longitudinal orientation plane of the first part (12), in which are accommodated the screw (18) and the nut (24), of which at least a portion (32, 34) engages with an abutment surface (46) of the housing (44) in such a way as axially to immobilize the nut (24) when a clamping force is applied, and
• a second part (14) of generally transverse orientation, at right angles to the plane of the first part (12), comprising at least a first bearing surface (50) and a second bearing surface (52) which, in the assembled position, engage respectively with a reaction surface (54) on the first part (12) and with a clamping surface (56) on the screw (18) in which the threaded rod (22) of the screw (18) extends axially through the second part (14) in such a way that a portion (28) of the screw (18) applies an axial clamping force to said second bearing surface (52) to immobilize the first and second parts (12, 14).
