A vehicle occupant restraint system includes a seat base pivotally connected to a seat mounting point and seat back pivotally connecting to the seat base. The seat base pivot reside proximal to a forward edge of the seat base and the seat back pivot resides proximal to a rearward edge of the seat base. Each pivot includes a toothed rack, and an engaging member for locking the pivot. The teeth define a radius about the pivots. The engaging members are attached to the seat base and are actuated by levers attached to the seat base. A harness is attached to the seat to prevent injury of an occupant in the event of a unanticipated maneuver, crash, rough terrain, or turbulence. The restraint system comprises a robust mechanism to withstand crash loads and offer sufficient adjustment between sitting and standing positions to accommodate an occupant's duties.
