Abstract
In this buckle device, when a second wind of a belt is pulled out from a spool, a load at which the belt is permitted to be pulled out is small, whereas slide resistance of the belt with respect to a slide face is large. When a first wind of the belt is then pulled out from the spool, the belt pull-out permitting load is large, whereas the slide resistance of the belt with respect to the slide face is small. This enables variation in a load at which extending of a buckle body is permitted to be suppressed.
Claims11
A buckle device comprising:
- a buckle body configured to engage with a tongue provided at a webbing worn by an occupant;
- a coupling member coupled to the buckle body;
- a take-up shaft onto which the coupling member is wound, that is coupled to the buckle body via the coupling member, that is configured to limit pull-out of the coupling member, and that is configured to permit pull-out of the coupling member at a pull-out permitting load or greater so as to permit extending of the buckle body;
- and
- a slide section across which the coupling member is configured to slide,
- wherein, when pull-out of the coupling member from the take-up shaft is permitted, a combined radius of the coupling member and the take-up shaft at a pull-out position of the coupling member from the take-up shaft becomes smaller so that a slide resistance of the coupling member with respect to the slide section becomes smaller.
