1. Method for restraining an occupant on a vehicle seat, comprising:

  • pulling the occupant into the vehicle seat with a predetermined pullback force by a reversible belt tensioner when a critical driving state is detected so that the occupant moves backward toward the vehicle seat, wherein the critical driving state may, but does not necessarily, lead to an accident, subsequently holding the occupant in a pulled-back position on the vehicle seat with a predetermined holding force, wherein the predetermined holding force is lower than the predetermined pullback force, and if the critical driving state ceases at any time without an accident, reversing the reversible belt tensioner to release pulling or holding force.
