摘要

本文从高性能座椅结构和头约束的角度讨论了严重后碰撞中乘员保护问题。考虑到固定头枕和可展开头枕。利用二维计算机模拟各种追尾碰撞中的乘员运动学，为头枕设计配置提供初始性能标准。最终的原型系统在冲击台车上进行了测试和开发。讨论了各种原型性能的结果和高性能头枕系统的一般标准。/ SAE /

OCCUPANT PROTECTION IN REAR END COLLISIONS

THIS PAPER DISCUSSES THE PROBLEM OF OCCUPANT PROTECTION IN SEVERE REAR END COLLISIONS FROM THE STANDPOINT OF HIGH PERFORMANCE SEAT STRUCTURES AND HEAD RESTRAINTS. CONSIDERATION IS GIVEN TO BOTH FIXED HEAD RESTRAINTS AND TO DEPLOYABLE HEAD RESTRAINTS. TWO-DIMENSIONAL COMPUTER SIMULATIONS OF OCCUPANT KINEMATICS IN A VARIETY OF REAREND COLLISIONS ARE UTILIZED TO PROVIDE INITIAL PERFORMANCE CRITERIA FOR HEAD RESTRAINT DESIGN CONFIGURATIONS. THE RESULTING PROTOTYPE SYSTEM UNDERWENT A TEST AND DEVELOPMENT PROGRAM ON AN IMPACT SLED. THE RESULTS OF THE VARIOUS PROTOTYPE PERFORMANCES AND GENERAL CRITERIA FOR HIGH PERFORMANCE HEAD RESTRAINT SYSTEMS ARE DISCUSSED. /SAE/
