  • Patent number: 4659108
    Abstract: A seat belt system of the conventional three point restraint type includes an electric motor which replaces the usual rewind spring on the belt retractor. When the seat belt is buckled up, the motor is set into operation and pulls the shoulder belt up into engagement with the body of the occupant in the seat, and then is pulsed backward to provide safe tensionless comfort in which the seat belt is located close to the body of the person being restrained but safely spaced away from the body of the occupant. The cycle of tightening of the belt and then releasing it by a predetermined short distance to provide the tensionless comfort position is repeated whenever the occupant either closes the seat belt buckle, shifts the position of the seat by operating the seat release or seat reclining levers, or leans forward beyond the tensionless range, thereby applying tension to the seat belt.
