2.  If shock is applied to the belt, rotation of the retraction shaft is stopped and the retractor is in the ELR condition. Under the ELR condition, the belt locks to secure the passenger’s body.

3.  Depending on the increase in weight applied to the belt under the ELR condition, the drum takes in rotation force in the direction that the belt webbing is being fed out.

4.  If the weight applied to the belt exceeds the specified value, the spool begins to rotate and the torsion bar twists. As a result, belt webbing is fed out, the restraining force of the belt loosens, and the load limiter condition is canceled. (Load limiter condition)
