Abstract

Automobile seat belts reduce the risk of injuries and fatalities resulting from a crash. As seat belts become more prevalent on large school buses, characterizing the capabilities of children to operate the unlatching mechanism of a seat belt is crucial to ensure the post-crash safety of young passengers. This study evaluated the strength capabilities of children and their abilities to unlatch a school bus seat belt when a school bus is in both the upright and rolled-over orientations. Push force exertions on a seat belt buckle push button were measured and compared to the seat belt assembly release force requirements specified in Federal Motor Vehicle Safety Standard (FMVSS) No. 209. Results of the study suggested that children do not have the strength to exert the maximum force of 133 N to release a seat belt assembly as specified in FMVSS No. 209; however, most children could unlatch a typical school bus seat belt assembly in the upright and rolled-over orientations.

解开校车安全带扣：年轻乘客的注意事项

汽车安全带可降低碰撞造成伤亡的风险。随着安全带在大型校车上的普及，确定儿童操作安全带解锁装置的能力对于确保小乘客的碰撞后安全至关重要。本研究评估了儿童的力量以及他们在校车直立和翻滚状态下解开校车安全带的能力。对安全带扣按钮的推力进行了测量，并与联邦机动车安全标准（FMVSS）第 209 号中规定的安全带总成释放力要求进行了比较。研究结果表明，儿童没有力量施加 FMVSS 第 209 号规定的 133 牛顿的最大力来松开安全带总成；但是，大多数儿童可以在直立和翻转方向上松开典型的校车安全带总成。
