滚子相对地设置在用于从牵引器拉出的安全带的抽出口处。当发生冲击载荷时,转动两个滚子以紧紧抓住其间的座椅带。因此,防止了可归因于带子的伸长和紧密缠绕的剩余长度被拉出。
Rollers are opposingly disposed at a drawing-out port for a seat belt webbing which is drawn out from a retractor. When an impact load has occurred, both the rollers are turned to tightly hold the seat webbing therebetween. Thus, a surplus length which is ascribable to the elongation and tight winding of the webbing is prevented from being drawn out.
