Abstract
An energy absorbing device for carrying a passenger seat; the device comprises a base fixed to a vehicle; a member displaceable from base; at least one energy-absorbing arrangement interconnecting base and displaceable member. The energy-absorbing arrangement comprises a plastically deformable absorbing element in response to stresses greater than a predetermined threshold stress. In some embodiments the plastically deformable absorbing element is a helically configured ribbon having spaced-apart ribbon laps. In other embodiments the plastically deformable absorbing element is compressible, and/or extendable. A method of attenuating the acceleration applied to a passenger due to impact is disclosed; the method comprises steps of: providing an energy absorbing device fixedly attaching the base to the vehicle; fixedly attaching the passenger seat to the base; accidently applying the impact to the vehicle; displacing the displaceable member relative to the base; attenuating the effect of the impact on the passenger.
