A restraint system 16 includes a housing 20 and a rotor 22 engaged with the housing. The housing and the rotor define a cavity 24 therebetween. A resilient material 26 is disposed in the cavity. A helical interface/screw 28 is between the housing and the rotor. The rotor is moveable relative to the housing. A seat belt buckle (Figure 2A, 18) 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 compressing the resilient material between the rotor and the housing (figure 3A to 3B). The resilient material may be a liquid containing hydrophobic nanoporous particles.
