Mechanical joining system between two components of varying thickness that eliminates lateral movement between them as used in the assembly of car seats

摘要

The conical flanged hole (4) in the second piece (2) is clamped between the conical cut out in a nut and a conical shoulder (32) on an assembly item (3) connected to the first piece thus preventing lateral movement. The system of joining one piece (1) onto a second piece (2) of varying thickness, consists of an assembly item (3) connected to the first piece and passing through a hole in the second piece which is in the form of a conical flange (4). This conical flange is radially clamped between a conical cut out (52) formed in a nut (5), screwed to the assembly item (3), and a conical shoulder (32) of the assembly item. This conical part (32) has a diameter so adapted that it can be inserted into the conical flange (4) when the pieces are assembled. The nut (5) applies a clamping pressure against the second piece (2).
