Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
167 words
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.
Claim 2
Dependent Claim
167 words

Claim 3
Dependent Claim
17 words
The arrangement according claim 1, wherein the emerging material has a spiked structure at the energy-absorbing elevation.
Claim 4
Dependent Claim
16 words
The arrangement according to claim 1, wherein the pressure generator is a pyrotechnically operating pressure generator.
