Abstract
A motor vehicle impact protection arrangement protects persons and has an impact protection device which is rendered operative in a defined protection area only when the danger of an impact is signalled. An energy-absorbing material is provided so that, when a danger of an impact has not yet been signalled, the material is situated in a closed space below the impact protection area and emerges only when the danger of an impact is signalled as an energy-absorbing impact protection device in the defined impact protection area.
Claims3
Motor vehicle impact protection arrangement which is rendered operative in a defined protection area only in an event of a signalled impact danger of an impact, comprising
- an energy-absorbing material which, when prior to the signalled impact danger is arranged in a closed space covered by the defined protection area,
- at least one of openings and predetermined weak points provided in the defined protection area and configured to be broken open or deformed by pressure exercised by the energy-absorbing material, through or into which the energy-absorbing material emerges after the signalled impact danger and form an energy-absorbing elevation, and
- a pressure generator configured to be actuatable by an impact signal and arranged relative to the energy-absorbing material so that, in an actuated state, the pressure generator exercises pressure on the energy-absorbing material to cause the energy-absorbing material to emerge to the energy-absorbing elevation wherein the predetermined weak points are configured as cups one of formed and molded on one side into a thin wall of a vehicle.
