Child Safety Seat with Advanced Harness System

项目总结/摘要 明尼苏达州健康解决方案（MHS）建议为机动车儿童开发先进的安全带系统 安全座椅车祸是美国儿童死亡的主要原因。共计2590人 2010- 2013年，12岁或12岁以下的儿童因意外机动车交通事故死亡， 数十万人受伤。如果使用得当，儿童安全座椅是最有效的方法， 保护卷入机动车碰撞事故的幼儿免受严重伤害或死亡。一种儿童安全座椅安全带， 通常为5点座椅安全带织带系统，将儿童约束在座椅中。在这一点上， 在碰撞开始时儿童的躯干与儿童所经历的头部偏移量直接相关 并且在儿童被扣入座椅时安全带中的任何松弛都会导致头部偏移增加。 头部偏移与儿童在撞车时头部受伤密切相关。尽管正确的 张紧安全带时，它通常是欠张紧的。一个常见的原因是脊甲往往是在- 张紧的事实是，线束张紧在物理上是困难的，特别是在面向后的位置，在较小的 用于身体虚弱或残疾人的车辆，用于无法进入车辆后部的人， 儿童安全座椅等。需要改进儿童安全座椅的设计，以减少 线束张紧不当。一种新颖的新型儿童安全座椅提出，以解决这一需要，并减少头部 儿童在车祸中受伤。

Project Summary/Abstract Minnesota HealthSolutions (MHS) proposes to develop an advanced harness system for motor vehicle child safety seats. Motor vehicle crashes are the leading cause of death for American children. A total of 2,590 children aged 12 years or younger died as a result of unintentional motor vehicle traffic crashes from 2010-13 and hundreds of thousands more were injured. When used properly, child safety seats are the most effective way to protect young children involved in motor vehicle crashes from serious injury or death. A child safety seat harness, typically a 5-point seat belt webbing system, restrains the child in the seat. The tightness of the harness on the child's torso at the onset of the crash is directly related to the amount of head excursion experienced by the child and any slack in the harness at the time the child is buckled into the seat results in increased head excursion. Head excursion is closely linked with head injuries in children during crashes. Despite the importance of correctly tensioning the harness, it is often under-tensioned. A common reason that harnesses are so often under- tensioned is the fact that harness tensioning is physically difficult, particularly in the rear-facing position, in smaller vehicles, for physically weak or disabled persons, for persons who are unable to fit inside the rear of a vehicle with a child safety seat, etc. Improvements are needed in child safety seat design to decrease the prevalence of improper harness tensioning. A novel new child safety seat is proposed to address this need and reduce head injuries in children during crashes.
