    • A vehicle seat (10) which carries a passenger restraint system, namely a lap belt (30) and a shoulder belt (28), with a tension load carrying member (64) being provided to resist forward rotation and bending of the backrest frame (14) during a frontal vehicle collision when the shoulder belt (28) is loaded in tension. The tension load carrying member (64) forms a truss structure with the frame back portion (42) and the frame base portion (36). However, during normal vehicle operation, the tension load carrying member (64) is detached from the frame back portion (42) eliminating the truss structure and the need for a more complex recliner mechanism for adjusting the position of the backrest (14). A grip mechanism (76, 80) is provided to attach the load carrying member (64) in response to a high shoulder belt (28) load to complete the truss. In an alternative embodiment, the load carrying member (130) is released from the backrest (14) only during adjustment of the backrest (14).
    • 一种车辆座椅(10),该车辆座椅(10)携带乘客约束系统,即腰带(30)和肩带(28),并且设置有拉力承载构件(64)以抵抗靠背框架的正向旋转和弯曲 14)在正面车辆碰撞期间当肩带(28)被张紧时被加载。 张力承载构件(64)与框架后部(42)和框架基部(36)形成桁架结构。 然而,在正常的车辆操作期间,拉紧载重部件(64)从框架后部(42)拆除,从而消除了桁架结构,并且需要用于调节靠背(14)的位置的更复杂的斜倚器机构。 提供夹持机构(76,80)以响应于高肩带(28)负载而附接承载构件(64)以完成桁架。 在替代实施例中,仅在靠背(14)的调节期间,负载承载构件(130)从靠背(14)释放。
