Definitions

  • the invention relates to a stem of a motor vehicle according to the preamble of claim 1.
  • the energy absorbing material is arranged next to the areas which are at a minimal distance from the underside of the bonnet. This means that bottlenecks that result from surveys on the top of the aggregate or from surveys in the shell of the stem are not covered by energy-absorbing materials. When a force acts on this constriction, a maximum deformation path is made available. The necessary energy absorption is realized by the surrounding areas.
  • the invention avoids the fact that the remaining block length of the energy absorber must also be taken into account in areas of narrow points. Due to the arrangement of the energy absorbing material next to the constriction, the remaining block length does not come into play, so that the bonnet manages with a minimal distance to the component below.
  • the component below the bonnet is a damper dome, the energy-absorbing material being arranged in a ring around a highest elevation of the damper dome. This means that in the event of an impact in the area of the damper dome, the energy-absorbing material is first compressed, namely up to a defined remaining block length. This remaining block length is dimensioned such that it does not exceed the highest elevation of the damper dome with maximum compression.
  • Figure 1 shows a longitudinal section through a stem 1 of a motor vehicle, not shown.
  • the longitudinal section is at the level of a damper dome 2, which is arranged below a hood 3.
  • the damper tower 2 has a highest point 4, which has a minimum distance A m i n the bottom 3a of the hood.
  • An annular depression 5 is arranged around the circular elevation 4 and has a maximum distance A max from the underside 3a of the hood 3.
  • Energy-absorbing material 6 is accommodated between the annular recess 5 and the underside 3a of the hood 3.
  • the energy-absorbing material 6 is arranged in a ring around the elevation 4 of the damper dome 2.
  • the energy-absorbing material 6 has only a circular cutout ⁇ ⁇ above the elevation 4 and otherwise extends over the entire underside 3a of the hood 3.
  • the bonnet 3 If a pedestrian collides in the area of the damper dome 2 (shown here with an arrow F), the bonnet 3 is deformed in the direction of the arrow F. The energy-absorbing material 6 is compressed, so that energy can be dissipated.
  • the necessary residual block length R of the energy absorbing material 6 is due to the arrangement according to the invention not on the elevation 4, but on the recess 5 of the damper dome 2.
  • the hood 3 can execute a maximum deformation path in the region of the circular recess 6 ⁇ , which is the minimum Distance A m ⁇ n corresponds.
  • the expansion of the energy-absorbing material 6 can be locally limited or extended under the hood 3. to be in order.
  • the energy-absorbing material 6 is provided with an optically appealing cover layer and can therefore simultaneously take over the function of the engine compartment lining.
  • the energy absorbing material 6 can be dimensioned to be smaller in size than the cover layer.

Abstract

L'invention concerne un avant-corps (1) d'un véhicule automobile qui comprend un capot (3) se trouvant à une certaine distance de composants (2) placés sous le capot. Un matériau (6) à absorption d'énergie est placé entre les composants (2) et le dessous (3a) du capot (3). L'invention vise à augmenter la liberté et la générosité structurelles dans la zone de l'avant-corps d'un véhicule automobile tout en remplissant les exigences de protection envers les piétons. A cet effet, le matériau à absorption d'énergie est placé à côté de zones qui présentent une distance minimale Amin par rapport au dessous (3a) du capot (3).
