Webbing take-up device and vehicle equipped with such a device

摘要

A webbing take-up device (10) and a vehicle are provided in which different force limiter loads can be selected at arbitrary times with a simple structure. A wire (28) is inserted into a spool (14). One end portion of the wire (28) is fixed to a lock base (16). Thus, when rotation of the lock base (16) is impeded, a twisting load of a torsion bar (24) and a drawing-through load of the wire (28) are applied to a webbing (26) as force limiter load. Further, a cutting gear (30) is disposed between the spool (14) and the lock base (16). When the cutting gear (30) is rotated at an arbitrary time, the wire (28) is cut. In this way, the force limiter load is reduced to only the twisting load of the torsion bar (24). As a result, different force limiter loads can be selected at arbitrary times with a simple structure. <IMAGE>
