<p>The vehicle seat structure comprises a back frame (A) composed of two uprights (2,3) connected by a cross member (5). The uprights are connected to the seat frame (B) by a fixed or pivoting connector. The seat belt thoracic branch (7a) is fixed to one (2) of the uprights. The belt abdominal branch (7b) and the fastener are fixed onto the seat frame. The seat frame upright (2) is a light alloy extruded section, whose tubular body is reinforced by longitudinal side to rear caissons. This tubular body receives, by force fitting in its fixing zone with a cross member (4), an insert (24). The insert has a transverse bore coincident with transverse bores in the upright (3). Each cross member end passes through one or other uprights. The corresponding insert is connected in translation to this upright by driving its end against the external face of the upright and by plating a circular rib against the upright internal face. It is connected in rotation by radial notches penetrating into the insert.</p> |
