According to the present invention, a bumper system 1 comprises: a rear wall 12 of a bumper beam 10 provided with hole parts 16, 17; and a bumper stay 20 which has pipe-like parts 21, 22 extending in the longitudinal direction of the bumper stay, the pipe-like parts 21, 22 being inserted into the hole parts 16, 17 and expanded and joined to the hole parts 16, 17. The bumper stay 20 has, in a cross-section perpendicular to the longitudinal direction, an extraction inhibiting part 24 that protrudes from the outer surfaces of the pipe-like parts 21, 22. The extraction inhibiting part 24 makes contact with the rear wall 12 of the bumper beam 10 in a direction A1 in which the bumper stay 20 is extracted from the hole parts 16, 17.

    Selon la présente invention, un système pare-choc (1) comprend : une paroi arrière (12) d'une traverse pare-choc (10) dotée de parties trous (16, 17) ; et un support pare-choc (20) qui présente des parties de type tuyau (21, 22) s'étendant dans la direction longitudinale du support pare-choc, les parties de type tuyau (21, 22) étant insérées dans les parties trous (16, 17) et étendues et jointes aux parties trous (16, 17). Le support pare-choc (20) a, dans une section transversale perpendiculaire à la direction longitudinale, une partie empêchant l'extraction (24) qui dépasse des surfaces externes des parties de type tuyau (21, 22). La partie empêchant l'extraction (24) entre en contact avec la paroi arrière (12) de la traverse pare-choc (10) dans une direction A1 dans laquelle le support pare-choc (20) est extrait des parties trous (16, 17).

    バンパーシステム1は、孔部16,17が設けられたバンパービーム10の後壁12と、長手方向に延びる管状部21,22を有し、管状部21,22が孔部16,17に挿通されるとともに孔部16,17に対して拡管接合されたバンパーステイ20とを備える。バンパーステイ20は、長手方向に垂直な断面において管状部21,22の外面から突出する引抜障害部24を有している。引抜障害部24は、バンパーステイ20が孔部16,17から引き抜かれる向きA1においてバンパービーム10の後壁12に当接している。
