A vehicle body front structure and an impact absorbing method thereof, in which an impact force applied to front side members is efficiently absorbed by an intended deformation of a reinforcing member. A part of the impact force applied to the front side members (12) is received by supporting forces in axial directions of a dash cross member (20) and a pillar brace (22). A recess (24) is provided in the dash cross member (20) in the portion thereof connected with the front side member (12). A recess (26) is provided in the pillar brace (22) in the portion thereof connected with the front side member (12). Due to the dash cross member (20) and the pillar brace (22) compressively deforming in the axial directions starting at these recesses (24), (26), the dash cross member (20) and the pillar brace (22) absorb impact force which is applied to the front side members (12) from the front of the vehicle.
La présente invention concerne la structure avant d'une carrosserie de voiture destinée à l'absorption efficace d'une force d'impact s'exerçant sur un élément latéral avant, grâce à la déformation voulue de renforcements. Une partie d'une force d'impact exercée sur un élément latéral avant (12) est absorbée par les forces de soutien d'un élément transversal (20) du tablier et d'une poutre de renfort (22) dans les directions axiales de ceux-ci. Il y a un renfoncement (24) dans l'élément transversal (20) du tablier, à la jonction de celui-ci avec l'élément latéral (12) de la partie avant, et il y a aussi un renfoncement (26) dans la poutre de renfort (22), à la jonction de celle-ci avec l'élément latéral avant (12). L'élément transversal (20) et la poutre de renfort (22) subissent une déformation par compression dans leurs directions axiales, laquelle déformation commence aux renfoncements (24, 26), et ils absorbent ainsi la force d'impact exercée sur l'élément latéral avant (12) depuis l'avant de la carrosserie.
