安全带带感锁止机构锁止时间的研究

The Study of Seatbelt Locking Time for the Belt Sense Locking Mechanism

运用人机工程的研究方法,解析出在车辆减速时造成的人体运动与安全带织带被拉出之间的运动关系,由此提出了安全带结构系数的新概念。对安全带带感锁止机构进行了动力学解析,推导出锁止时间以及相关的计算公式。

With human engineering as the research method, this paper analyzes the relationship between the movement of the human body and the seatbelt webbing pulled out when the vehicle decelerates, on the basis of which the seatbelt structural coefficient is put forward. The locking time and relevant formulas are deduced by means of analytical model performed on seatbelt locking mechanism.
