WIPO Patent Application WO/2021/040420
Kind Code:
A1
Abstract:
Provided is a seat belt retractor having a vehicle sensor, the retractor comprising: a fixing frame connected to a vehicle body; a spool which is mounted on the fixing frame so as to be rotatable around a shaft disposed in a set direction, and around which a seat belt is externally wound; a control disc which is connected to the shaft around which the spool rotates, so as to rotate together with same, and which has an external toothed part; a vehicle sensor unit, which senses a change in the acceleration of a vehicle by means of the movement of an inertial body so as to prevent rotation of the control disc; and a mounting member mounted in a housing coupled to one side wall of the fixing frame, wherein the vehicle sensor unit is directly coupled to the mounting member so as to be rotatable, and thus the number of components for mounting the vehicle sensor unit is reduced so as to improve workability during an assembly operation, and enable manufacturing costs to be reduced.
