Abstract

L'invention fournit : un élément récepteur d'impact permettant de disperser de manière plus efficace et à l'aide d'une pièce de couplage, une contrainte appliquée depuis une partie montage sur une plaque face arrière lorsque l'élément récepteur d'impact reçoit une charge depuis l'avant ; et une défense dans laquelle l'élément récepteur d'impact est disposé sur une partie face arrière d'un corps principal de défense. Plus précisément, l'invention concerne un élément récepteur d'impact (10) disposé sur la partie face arrière du corps principal de défense (2), et équipé : d'une plaque face arrière (11) positionnée côté corps principal de défense ; d'une plaque face avant (12) en vis-à-vis avec la plaque face arrière (11) ; d'une pièce de couplage (14) couplant la plaque face avant (12) et la plaque face arrière (11) ; et d'une partie montage (20) possédant une partie liaison de plaque face arrière liée à la face arrière de la plaque face arrière (11). L'élément récepteur d'impact (10) est caractéristique en ce que lorsqu'une face transversale d'extrémité arrière de la pièce de couplage (14), et la face transversale d'extrémité avant d'une partie liaison de plaque face arrière (21b), est projetée sur une face de projection commune sensiblement perpendiculaire à la ligne axiale du corps principal de défense (2), la surface d'une portion de la face transversale d'extrémité arrière de la pièce de couplage (14) se superposant à la face transversale d'extrémité avant de la partie liaison de plaque face arrière (21b), à l'intérieur de la face de projection, est supérieure ou égale à 25% de la surface de l'ensemble de la face transversale d'extrémité avant de la partie liaison de plaque face arrière (21b).
