Definitions

  • the invention relates to a motor vehicle according to the preamble of claim 1.
  • crumple zones An essential safety element of modern motor vehicles are the so-called crumple zones, which are present in particular in front of and behind the deformation-resistant passenger compartment. These crumple zones are designed in such a way that they deform in a targeted manner in the event of an accident, so that the very sudden braking, for example the front bumper suffers in the event of a front impact, is converted into a softer braking of the interior, which increases the chance of survival for the vehicle occupants ⁇ sen enlarged.
  • the extended bumper can be run over by an impacting vehicle, so that the crumple zone achieved by the extended bumper is ineffective.
  • the invention has for its object to provide a generic motor vehicle with increased accident safety.
  • the design of the motor vehicle according to the invention ensures that the risk of injury, in particular for pedestrians, is considerably reduced, since the flat outer skin part covers a pedestrian over a large area and does not knock him down. Furthermore, the extended, flat outer skin part cannot easily be run over by the bumper of an opposing vehicle, as a result of which the crumple zone formed by the extended flat outer skin part is reliably effective. Furthermore, an additional material is available for energy reduction.
  • Claim 3 characterizes a very advantageous embodiment of the motor vehicle, in which the flat outer skin part forms a kind of protective shield in front of the vehicle together with the front bumper.
  • the claim 5 is directed to an embodiment in which a high level of safety is achieved even in the event of a rear-end collision, which is particularly the case in compact vehicles in which there is little space behind the front passengers, or also in combination vehicles in which the rear loading space, for example, is one Child seat takes up is important.
  • Claims 7 to 9 are directed to particularly simple but very effective embodiments of the deformable support parts or struts.
  • the surface of the flat, extendable outer skin part is used in a particularly effective manner, an appropriately constructed air bag being additionally very economical in weight and capable of reducing energy.
  • occupant safety is additionally increased, since the air cushion arranged in the vehicle interior prevents a vehicle occupant from colliding with hard interior structures.
  • This additional air cushion is very inexpensive because it does not require its own release or inflator.
  • the airbag is used not only for energy dissipation in the event of an accident, but also for moving the flat outer skin part.
  • the force-displacement characteristic or the energy absorption capacity of the crumple zone can be adapted to the respective requirements, for example the vehicle speed or the vehicle load.
  • the gas pressure in the airbag is lower than in the case of a heavily loaded vehicle when the vehicle is not heavily loaded, so that the crumple zone comprising the airbag and the flat outer skin part is sufficiently “softly” deformable.
  • the force-displacement characteristic of the crumple zone can be adapted to the respective requirements by appropriate selection of the chambers and the valves.
  • the pressure source is a pressure accumulator
  • the gas used to inflate the airbag can be pumped back and forth in a simple manner between the airbag and the accumulator. This saves the air drying effort if ambient air is used as the gas.
  • part of the gas can also be stored in air cushions when the airbag is not inflated.
  • Claim 17 characterizes an embodiment of the motor vehicle which can be constructed inexpensively as a compact vehicle for a wide variety of uses and at the same time has a high level of safety.
  • the impact protection module can be a completely separate unit that is adapted to the respective requirements and the permissible costs.
  • Claim 18 characterizes a particularly advantageous embodiment of the vehicle, in which, in addition to the "braking path" possible for the vehicle occupant due to the extendable outer skin part, the path by which the seat can be displaced in the event of a crash is used to improve safety that the passenger sitting on it is endangered.

Abstract

Un véhicule à moteur, notamment un véhicule compact, comprend une structure de carrosserie rigide en soi qui contient un espace utile et qui porte des parties plates (8, 10, 12) qui forment son revêtement extérieur. Le véhicule comprend une unité de protection contre des collisions au moyen de laquelle une partie du véhicule est déplacée d'une position repliée à une position déployée dans laquelle la surface de base du véhicule est accrue. Lorsque le véhicule heurte un obstacle, la partie déployée du véhicule réduit les déformations de l'espace utile en se déplaçant en direction du véhicule. La partie déployable du véhicule est constituée d'une des parties plates (8, 10, 12) qui forment le revêtement extérieur du véhicule.
