  • Shock absorbing height adjusters for restraint systems and associated systems and methods
    Patent number: 9809193
    Abstract: Shock absorbing seatbelt height adjusters for use with vehicle occupant restraint systems, and associated systems and methods are disclosed herein. In one embodiment, a shock absorbing height adjuster includes a D-loop assembly slidably coupled to a rail, and a stop assembly and a pre-loader slidably coupled to the rail on opposite sides of the D-loop assembly. The stop assembly and the pre-loader can be releasably lockable at a plurality of positions along the rail. A biasing member can be compressed between the pre-loader and the D-loop assembly to urge the D-loop assembly toward the stop assembly and allow motion of the D-loop assembly toward the pre-loader under load. The position of the pre-loader can be adjusted to vary the compression in the biasing member.
