摘要

通过对追尾碰撞中前排乘员运动学的二维计算机模拟，确定了不同碰撞速度下展开时间和约束配置的初始性能标准。基于这些准则，设计并构建了两种类型的可展开系统，一种是充气系统，另一种是刚性滑动系统。然后，这些原型系统使用拟人化假人和冲击雪橇进行了测试和开发程序。测试项目评估了头枕系统在高速和低速碰撞模拟下的有效性。此外，还进行了试验，以研究约束部署对错位乘员的影响。讨论了试验方案的结果，并将两种原型系统与现有头枕设计进行了比较。/ SAE /

DEPLOYABLE HEAD RESTRAINTS-A FEASIBILITY STUDY

STARTING WITH TWO-DIMENSIONAL COMPUTER SIMULATIONS OF FRONT SEAT OCCUPANT KINEMATICS IN REAR-END COLLISIONS, INITIAL PERFORMANCE CRITERIA FOR DEPLOYMENT TIMES, AND RESTRAINT CONFIGURATIONS WERE DETERMINED FOR VARIOUS IMPACT VELOCITIES. BASED ON THESE CRITERIA, TWO TYPES OF DEPLOYABLE SYSTEMS WERE DESIGNED AND CONSTRUCTED, ONE AN INFLATABLE SYSTEM AND THE OTHER A RIGID SLIDING SYSTEM. THESE PROTOTYPE SYSTEMS THEN UNDERWENT A TEST AND DEVELOPMENT PROGRAM USING ANTHROPOMORPHIC DUMMIES AND AN IMPACT SLED. THE TEST PROGRAM EVALUATED THE EFFECTIVENESS OF THE HEAD RESTRAINT SYSTEMS UNDER HIGH- AND LOW-SPEED CRASH SIMULATIONS. IN ADDITION, TESTS WERE PERFORMED TO STUDY THE EFFECT OF RESTRAINT DEPLOYMENT ON THE MALPOSITIONED OCCUPANT. THE RESULTS OF THE TEST PROGRAM ARE DISCUSSED AND COMPARISONS ARE MADE BETWEEN THE TWO PROTOTYPE SYSTEMS AND EXISTING HEAD RESTRAINT DESIGNS. /SAE/
