Abstract

The invention relates to an automobile comprising a front cross-member (7), an attachment element (6) arranged at the rear of said cross-member (7), a bonnet (1) that closes off said engine compartment and has one free edge (11), and a front bumper (3) mounted in front of said front cross-member (7) and which has a central portion (33) which extends as far as said bonnet (1) and comprises a tab (83) for attaching to said attachment element (6). According to the invention, the attachment tab (83) comprises a frangible area (87), located to the front of said attachment area (85) and capable of breaking, and said frangible area (87) is arranged next to an empty space formed in said compartment, with a view to having the central portion (33) of said bumper (3) bend into said empty space when said frangible area (87) breaks.

Description

Background technique [0001] Most motor vehicles include an engine hood or an engine cover in which an upper air intake grille is formed. The grille is usually positioned between the headlights. The bumper or guard plate is positioned below the aforementioned air intake grille. In the case of a frontal collision with a pedestrian with a short stature, such as a child, for example, the pedestrian's head hits the engine hood located substantially above the upper air intake grille. The natural flexibility of the engine cover made of thin steel plate can absorb part of the impact force through the deformation of the engine cover. [0002] However, in the past few years, motor vehicles have had very bulky front bumpers for style reasons. These bumpers include a central portion that rises upward toward the hood between the headlights. Often this part of the bumper carries the upper air intake grille. The hood itself is shortened and its free edge is positioned quite high between the...
