A SAFETY ARRANGEMENT FOR A VEHICLE

摘要

A safety arrangement ( 1 ) is located beneath the hood or bonnet ( 3 ) of a motor vehicle and includes an inflatable element ( 8 ) which is formed of a plastically deformable material. A gas generator ( 14 ) supplies gas to inflate the element ( 8 ) in response to a signal from a sensor ( 18 ) which is responsive to impact with a pedestrian. The gas generator ( 14 ) passes gas to a chamber ( 15 ), and thus through a relatively small aperture ( 16 ) to inflate the element ( 8 ) with a gradual inflation. If a pedestrian strikes the bonnet, the pedestrian will not deform the bonnet and then be arrested by impact with an engine block or the like, and also the plastically deformable element ( 8 ) will deform to absorb energy.
