Abstract
Abstract A vehicle seat restraining system that includes one or more electromagnets located on the vehicle seat for magnetically restraining an occupant to the vehicle seat. Magnetically attractive members are also provided that are worn by the occupant that are adapted to be attracted by the electromagnets on the vehicle seat when the magnets are energized. A power source is also provided to energize the electromagnets on the vehicle seat.
