Patent ID: 7597500

Claim:
An assembly of two parts assembled by a screw-nut system, said assembly comprises: a first vertical planar part of generally longitudinal orientation comprising a housing that extends axially along a screw-fastening axis in the vertical of longitudinal orientation plane of the first part, said housing comprising a recess defined at a first distal axial end thereof which includes an abutment surface and a reaction surface, a second part of generally transverse orientation, at right angles to the plane of the first part, comprising at least a first bearing surface and a second bearing surface, said screw-nut system comprising a screw having a clamping surface and a rod, and a nut having a distal face and a proximal face and defining said screw-fastening axis, said nut and at least a threaded end portion of the rod are accommodated in the housing, said assembly being configured to immobilize the first and second parts in an assembled position, in said assembled position the rod of the screw extends axially through the second part in such a way that at least a portion of the clamping surface of the screw applies an axial clamping force to the first bearing surface, the reaction surface of the first part engages with the second bearing surface and at least a portion of the proximal face of the nut engages with the abutment surface of the housing of the first planar part to axially immobilize the nut, and said proximal face of said nut being closer to said second bearing surface than said distal face of said nut is to said second bearing surface, said second proximal axial end of said housing being closer to said second bearing surface than said first distal axial end of said housing.
