Definitions

  • the invention relates to a front end of a motor vehicle, consisting of frame side members, wheel arches and fenders, one / each on each side, a cross member with a front panel, and a front flap (also called a bonnet), the front flap being flush on each side but with a joint in between, adjoins an edge of the fender, which in turn forms a vertical wall starting from the edge, which is supported on the wheel arch and / or frame side member, and the front flap is resilient downwards when a body hits.
  • the flexible front flap is intended to reduce the risk of serious injuries in the event of a collision with a pedestrian - the impacting body is then a human, in particular a head.
  • the victim's upper body is usually pivoted backwards and downwards around the vehicle bow, so that the head then hits the front flap in the vertical direction. This is designed to mitigate this impact.
  • the vertical wall rests frictionally on a standing plate which is firmly connected to the wheel house or frame side member, the frictional connection between the vertical wall and standing plate being produced by means of a tension element penetrating a hole in the vertical wall and a hole in the standing plate , which brings about a compression spring, and one of the two holes is an elongated hole.
  • the frictional connection allows a very precise and reproducible setting of the molding behavior; not only its beginning but also its course.
  • the fender can be replaced very easily and without welding, for example after a collision.
  • One slot allows the different Exercise the two parts against each other without accompanying deformation of one of the two sheets.
  • the standing plate preferably forms an angled foot fastened to the wheel arch or frame side member, corner beads being formed in the angular zone (claim 2). This ensures that the frictional displacement in the event of a collision is not disturbed by premature bending or buckling of the standing plate.
  • the vertical wall of the fender extends down to the wheel house or frame side member and its lower edge is rolled in (claim 3).
  • the vertical wall of the fender extends down to the wheel house or frame side member and its lower edge is rolled in (claim 3).
  • the tension element can be a cap screw and the associated nut attached to the side of the fender facing away from the front flap (claim 5) or the tension element is a bolt with a footplate, the footplate being fastened to the side of the fender facing away from the front flap and the Mother with the front flap open is accessible (claim 6).
  • the spring force is particularly precisely definable if the compression spring is at least one plate spring (claim 7), which is designed either in accordance with the standard or as a radially slotted bell.

Abstract

L'invention concerne la partie avant d'un véhicule automobile comportant des longerons (8), des passages de roues (6) et des ailes (1), ainsi qu'un capot avant (3) affleurant avec le bord (13) des ailes, qui forment une paroi verticale (15; 25) à partir dudit bord, laquelle paroi s'appuie sur les passages de roues (6) et/ou les longerons (8), le capot avant (3) se déformant vers l'arrière en cas d'impact. L'invention vise à créer un support d'aile qui se retire vers l'arrière exactement comme il est souhaité en cas de collision. A cet effet, la paroi verticale (15) est adjacente par liaison de frottement avec une tôle verticale (17) reliée de manière fixe au passage de roue, la liaison de frottement étant créée par un élément de traction (21) associé à un trou (16) dans la paroi verticale (15; 25) et à un trou (20) dans la tôle verticale (17; 27), cet élément de traction faisant agir un ressort de pression (32) et un des deux trous (16, 20) étant oblong.
