A seat belt buckle pre-tensioning system is integrated in a seat assembly that includes a seat bottom and a seat back pivotally coupled with the seat bottom. When an impact event is detected (or predicted), the seatbelt assembly anchor point quickly moves forward and downward, causing the coupled waist seatbelt to be pre-tensioned and moved to a position that optimizes waist seatbelt geometry and prevents diving during the impact event. This may be accomplished using an explosive pre-tensioner, a mechanical pre-tensioner, and/or an electronic pre-tensioner with a suitable controller, and the pre-tensioner may be applied to waist belt anchoring points on one or both sides of the seat. The aim of this is to ensure that the pelvic bone of the occupant is sufficiently engaged with the waist belt of the seat assembly and does not slide out from below the waist belt during an impact event, thereby preventing diving.
一种座椅安全带带扣预拉紧系统,其被集成在座椅组件中,座椅组件包括座椅底部和与座椅底部可枢转地联接在一起的座椅靠背。当检测到(或预测到)撞击事件时,安全带组件锚固点会迅速向前和向下移动,从而使得被联接的腰部安全带预拉紧并移动到在撞击事件期间优化腰部安全带几何形状并防止发生下潜的位置。这可以使用爆炸式预拉紧器、机械式预拉紧器和/或带有适当控制器的电子预拉紧器来完成,并且预拉紧器可应用于在座椅一侧或两侧上的腰部安全带锚固点。这样做的目的是确保在撞击事件期间乘员的盆骨与座椅组件的腰部安全带充分接合并且不会从腰部安全带的下方滑出,从而防止下潜。
