摘要： Provided are a seat belt retractor and a seat belt device capable of suppressing an increase in frictional resistance when a pretensioner is steadily driven and increasing the resistance to be applied to a webbing when energy is absorbed. A seat belt retractor includes a guide member facing at least a part of an outer circumferential surface of a locking base and disposed along an opening portion. The guide member is configured not to come into contact with the locking base until a pretensioner is shifted to a steady driving state, is configured to come into contact with the locking base when the pretensioner is steadily driven, and is configured to allow contact between lock teeth and the locking base when subjected to a predetermined load after the pretensioner is shifted to the steady driving state.

摘要： A curtain airbag and a curtain airbag device in which a stress applied from a front tether to a curtain airbag main body portion when inflation and deployment is distributed. An externally attached panel is disposed outside a front portion of a panel on a vehicle outer side among panels constituting a curtain airbag main body portion. An upper edge and a lower edge of the externally attached panel are sewn to the panels by a linear coupling portion. An intermediate portion of a rear edge of the externally attached panel in an upper-lower direction is sewn to the panels by an annular coupling portion. A rear portion of a front tether is sewn to a front portion of the externally attached panel.
