Abstract

La présente invention concerne un dispositif de fixation (3) d'un ensemble de fixation (2) pour la fixation d'un corps structural (5) à un élément structural (4), en particulier d'un véhicule automobile (1), l'élément structural (4) comprenant une ouverture d'immobilisation (8) dans laquelle le dispositif de fixation (3) peut être immobilisé pour la fixation du corps structural (5) à l'élément structural (4). Le dispositif de fixation (3) comprend deux éléments de fixation (9, 10) qui sont déplaçables axialement l'un par rapport à l'autre. Une immobilisation simplifiée du dispositif de fixation (3) à l'élément structural (4) est obtenue par le fait qu'un premier élément de fixation (9) du dispositif de fixation (3) peut être guidé à travers l'ouverture d'immobilisation (8) et est déplaçable radialement de telle sorte qu'une structure de mise en prise (11) du premier élément de fixation (9) vient en prise par l'arrière avec un bord (25) de l'ouverture d'immobilisation (8) et bloque ainsi axialement le premier élément de fixation (9) contre l'élément structural (4). Un deuxième élément de fixation (9) comprend une structure d'introduction (20) qui peut être introduite dans une section transversale résiduelle (26) de l'ouverture d'immobilisation (8) et bloque ainsi le premier élément de fixation (9) de manière à empêcher son déplacement dans une direction radialement opposée. L'invention concerne en outre un ensemble de fixation (2) comprenant un tel dispositif de fixation (3), l'ensemble de fixation (2) comportant de plus un tel élément structural (4) ainsi qu'un tel corps structural (5). L'invention concerne en outre un véhicule automobile (1) comprenant un tel ensemble de fixation (2), l'élément structural (4) étant en particulier réalisé sous la forme d'une carrosserie (6) du véhicule automobile (1).
