Abstract
Method and apparatus for limiting the load on a seat belt buckle, includes providing an adjustable energy absorbing device mounting the seat belt buckle on the vehicle, sensing vehicle and occupant conditions to determine the optimal adjustment of the adjustable energy absorbing device for restraint of the occupant under the sensed conditions, and adjusting the adjustable energy absorbing device in response to the sensed conditions to thereby adapt the restraint of the occupant to the sensed conditions. The adjustable energy absorbing device is an extendable strut having an end connected to the buckle and an end connected to the vehicle, said strut having metal deforming elements therein being deformed upon the load reaching a certain magnitude, and said strut having an adjusting mechanism adjusting the metal deforming elements to adjust the degree of metal deformation and thereby adjust the energy absorbing capacity of the strut.
