Title: Mechanical absorption systems for an active bonnet hinge

Abstract: The invention relates to a safety device for raising the bonnet of a motor vehicle in the event of a collision with a pedestrian. The safety device includes a pyrotechnic actuator provided with a thrust piston secured to a mechanism for raising the bonnet and able to deploy the said mechanism which is itself secured to the said bonnet, and a blocking device intended to block the said actuator in a given position. The main characteristic of this device is that it is made up of a shock-absorbing device employed when a pedestrian hits the bonnet which has been raised, so that the assembly consisting of the bonnet, the raising mechanism and the piston can move under the effect of the impact while at the same time being retarded.
