A tether actuation unit (50) is provided that includes an actuator (60) configured to form a connection with a tether (40) such that the tether can be released in response to actuation of the actuator, and a housing (80) configured to receive the actuator. The housing includes a tether channel (150) configured to allow the tether to extend through the tether channel. The tether channel includes a sidewall (156, 158, 160) configured to receive and engage the tether along a portion of a length of the sidewall when the tether extends angularly from the housing. A side wall of the tether channel is configured to limit movement of the tether in response to deployment of the airbag so as to limit tension applied to the actuator by the tether within a predetermined range in a non-orthogonal direction with respect to a central axis (A) of the actuator.
提供了一种系绳致动单元(50),该系绳致动单元包括致动器(60)和壳体(80),该致动器被配置成形成与系绳(40)的连接,使得可响应于致动器的致动来释放系绳,该壳体被配置成接纳致动器。壳体包括系绳通道(150),该系绳通道被配置成允许系绳延伸穿过系绳通道。系绳通道包括侧壁(156,158,160),侧壁被配置成当系绳从壳体成角度地延伸时沿侧壁的长度的一部分接纳并且接合系绳。系绳通道的侧壁被配置成限制系绳响应于气囊展开的移动,以便于将通过系绳向致动器施加的张力限制在相对于致动器的中心轴线(A)的非正交方向的预定范围内。
