12. A vehicle seat system for a vehicle seat mounted on a vehicle floor comprising:
-
a resilient vehicle seat bun for normally supporting a seated occupant at a given height above the vehicle floor; a lap restraint with first and second ends to cross over the seated occupant combined with a shoulder restraint with first and second ends to restrain the occupant in the vehicle seat; a pyrotechnic rotary belt wrench tensionally associated with the first end of the belt restraint to tension the lap restraint to an extent of an least 500 pounds force to significantly pull down toward the vehicle floor the seated occupant into the seat bun such that a head region of a seated occupant is brought closer to the vehicle floor; a pretensioner tensionally associated with the second end of the lap restraint to tension the lap restraint and shoulder harness first end working significantly faster to tension the lap restraint and shoulder harness before a completion of the tensioning of the lap restraint by the belt wrench; a signalled belt retractor providing an anchor for the second end of the shoulder restraint; and a sensor to activate the belt wrench and the pretensioner when the vehicle floor undergoes a displacement condition indicative of a vehicle rollover condition.

13. A method of confining a seated vehicle occupant in a vehicle in an attempt to minimize injuries in a rollover condition comprising:
-
normally supporting the seated occupant on a resilient vehicle seat bun at a given height above a floor of the vehicle; restraining in the vehicle seat the seated occupant by a belt restraint which crosses over the seated occupant'"'"'s lap; tensioning the belt restraint with a belt wrench tensionally associated with the belt restraint to an extent to significantly pull down toward the vehicle floor the vehicle occupant into the seat bun such that a head region of the seated occupant is brought closer to the vehicle floor; and sensing a displacement of the vehicle floor indicative of a vehicle rollover condition and thereafter signalling the belt wrench to tension the belt restraint. - View Dependent Claims (14, 15, 16)
