An airbag system has an airbag control module configured to detect a direction of impact of a vehicle; an airbag assembly having an airbag cushion with an internal tether, and a tether adjustment mechanism. The tether adjustment mechanism is in communication with the airbag control module and is in engagement with the tether. The airbag control module is configured to send a signal to the tether adjustment mechanism to adjust the tether by ratcheting a portion of the middle segment of the tether when the airbag cushion is unfolded, so that one of a first tether length and a second tether length is extended, and the other of the first tether length and the second tether length is contracted to provide a larger volumetric capacity of the airbag cushion in the direction of impact.
一种气囊系统,具有:气囊控制模块,配置成检测车辆的碰撞方向;气囊组件,具有带有内部拴系件的气囊衬垫;以及拴系件调节机构。拴系件调节机构与气囊控制模块通信并与拴系件接合。气囊控制模块配置成当气囊衬垫展开时,向拴系件调节机构发送信号,以通过棘齿配合拴系件的中间段的一部分来调节该拴系件,使得第一拴系件长度和第二拴系件长度中的一者延伸,而第一拴系件长度和第二拴系件长度中的另一者收缩,以沿碰撞方向提供更大的气囊衬垫的体积容量。
