Abstract
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.
Claims14
A safety arrangement for a motor vehicle having a hood or bonnet, the safety arrangement comprising an inflatable element formed at least partly of plastically deformable material dimensioned and adapted to be located under the rear part of the hood or bonnet, between the rear part of the hood or bonnet and a fixed part of the vehicle, means being provided to supply inflating gas to the inflatable element, wherein the means to supply inflating gas are adapted to supply gas through a throttle defining a gas flow path of a predetermined cross-sectional area, wherein the means to supply gas comprises a gas generator adapted to generate gas, the gas generator communicating with a chamber within the inflatable element, the chamber being provided with an aperture constituting said gas throttle.
A safety arrangement in a motor vehicle having a hood or bonnet, the safety arrangement comprising an inflatable element formed at least partially of a plastically deformable material, the inflatable element mountable in position between a fixed part of the vehicle and a rear part of the bonnet, means being provided to supply gas to the inflatable element, wherein the means to supply inflating gas are adapted to supply gas through a throttle defining a gas flow path of a predetermined cross-sectional area, wherein the means to supply gas comprises a gas generator adapted to generate gas, the gas generator communicating with a chamber within the inflatable element, the chamber being provided with an aperture constituting said gas throttle.
A safety arrangement for a motor vehicle, comprising:
- an inflatable element formed at least partially of a plastically deformable material, the inflatable element sized to be mounted underneath a rear portion of a vehicle hood;
- and
- a gas generator for supplying inflation gas to the inflatable element, wherein the means to supply inflating gas are adapted to supply gas through a throttle defining a gas flow path of a predetermined cross-sectional area, wherein the means to supply gas comprises a gas generator adapted to generate gas, the gas generator communicating with a chamber within the inflatable element, the chamber being provided with an aperture constituting said gas throttle.
