Abstract

The disclosed seat belt retractor may include a spool for retracting a seat belt, a torsion bar, a pre-tensioner, and a locking device. The torsion bar may disposed inside the spool, wherein one side of the torsion bar is connected to the spool, and configured to absorb energy of movement of an occupant while being deformed under torsion. The pre-tensioner may be positioned at one side of the spool and configured to generate a rotating drive force for rotating the spool in a retracting direction in a condition of rapid deceleration of a motor vehicle. The locking device may be capable of locking another side of the spool such that a rotation of the spool in a withdrawal direction is suppressed at both an operating time of the pre-tensioner and a non-operating time of the pre-tensioner.

Description

technical field [0001] The present invention relates to a seat belt retractor for winding a seat belt, in particular to a seat belt retractor with an EA mechanism and a seat belt device with the seat belt retractor, wherein the seat belt is locked under abnormal conditions When the movement of the occupant is restrained, the inertial energy applied to the occupant is absorbed by the EA mechanism. Background technique [0002] Seat belt devices installed on vehicle seats are essential for restraining the rapid movement of occupants due to the acceleration of the vehicle during a collision, so as to ensure the safety of the occupants' bodies. [0003] The seat belt device generally consists of a seat belt (webbing), a seat belt retractor and a buckle device. [0004] A retractor wraps a seat belt around a winding member (reel) and pulls it in by a spring force, and usually accommodates the seat belt in this pulled-in state. When the occupant wears the seat belt, by pulling t...
