ABSTRACT:
A vehicular seatbelt retractor includes a load control for controlling an excessive force applied to a web and a web sensor for sensing the webbing acceleration of a seatbelt to take counteraction against the abnormal state of a vehicle at a quick speed, in which the load control enables a disk to be frictionally engaged with one surface of a spool winding portion, thereby dissipating the force applied to a web, and a torsion bar coupled at one end with a boss to be cooperated with a spool, thereby controlling the force applied to the web and the web sensor enables a latch member elastically supported at one end by an inertia spring to sense the web acceleration in an adjusted time range along with a wing thereby to take counteraction against the abnormal state of a vehicle.
