Abstract
A restraint system includes a housing and a rotor engaged with the housing. The housing and the rotor define a cavity therebetween. A resilient material is disposed in the cavity. A helical interface is between the housing and the rotor. The rotor is moveable relative to the housing along the helical interface. A seat belt buckle is connected to and moveable relative to one of the housing and the rotor. During a vehicle impact, the seat belt buckle may cause the rotor to move along the helical interface towards the housing. In this situation, the resilient material may be compressed between the rotor and the housing.
