Patent abstract
Various embodiments of seat harness pretensioning devices for use in land, air, and sea vehicles are described herein. In one embodiment, a seat unit for use in a military land vehicle or helicopter includes a stroking device that enables the seat to move downwardly in response to an explosion or hard landing, respectively.

Downward movement of the seat in response to an explosion or hard landing causes a tensioning system to automatically pretension the seat harness.
