座椅安全带系统的当前设计可能对汽车乘员提供不足的保护。因此，乘员可能由于头部大幅度偏移而遭受头部损伤。胸部受伤可能是由于不利的约束几何形状或过度的安全带松弛。最后，由于身体上的高垂直载荷，可能会出现脊柱损伤。利用良好的生物力学约束的基本标准，提出了传统三点式安全带系统的设计改进。说明座椅的设计对安全带的生物力学防护效果有重要影响。提出了一种简单的传统座椅的重新设计。比较雪橇测试与一个新的座椅设计和传统的座椅。还研究了织带锁定B柱环和自动皮带张紧器的效果。Language：en
Current design of seat belt systems may provide insufficient protection for the car occupant. Thus occupants may sustain head injuries due to large head excursion. Chest injuries may occur due to unfavorable restraining geometry or excessive belt slack. Finally, spinal injuries may appear due to high vertical loads on the body. Using basic criteria of favorable biomechanical restraining, design improvements of a conventional three-point seat belt system are proposed. It is shown that the design of the seat is of great importance to the biomechanical protective effect of the seat belt. A simple redesign of a conventional seat is proposed. Comparative sled tests with a new seat design and with a conventional seat are performed. The effects of a webbing-locking B-pillar loop and of an automatic belt tightener are also studied.
