Abstract
In at least one embodiment of the present invention, a force limiting device for a motor vehicle is provided. The force limiting device is adopted for adjusting the absorption of a force between two parts moving relative to one another during a dangerous situation in the motor vehicle. The force limiting device comprises a kinematic energy absorption device configured such that for a predefined profile of a speed difference between the two parts moving relative to one another different force limiting levels are produced as a function of mass and momentum of the two moving parts.

A force limiting device for a motor vehicle adapted for adjusting the absorption of a force between a first part and a second part moving relative to one another during a dynamic condition in the motor vehicle, the force limiting device comprising a kinematic energy absorption device configured such that for a predefined profile of a speed difference between the first part and the second part moving relative to one another force limiting levels are produced by the force limiting device, the kinematic energy absorption device including a mass system which is placed into oscillation during the dynamic condition at a frequency that provides a restraining force acting between the first part and the second part, thereby affecting the speed difference between the first part and the second part relative to one another.
