摘要： Disclosed is a polyester sewing thread usable for a fabric for an airbag and a cushion for an airbag. A polyester sewing thread is obtained by doubling and twisting a specific polyester yarn including a plurality of polyester filaments, and bonding the polyester yarn in the manner of in-bonding, out-bonding, or in-and-out bonding. The polyester fiber has high strength, middle elongation, and dry heat shrinkage, and may be used as sewing threads with excellent physical properties similar to those of a sewing thread of existing polyamide fiber (Nylon 66). A method for producing the thread is also disclosed.

摘要： Disclosed is a side curtain airbag and an airbag system including the same. The side curtain airbag according to the present invention comprises an inflating part having gas inflation, a non-inflating part supporting the inflating part, and an adhered part constituting a boundary between the inflating part and the non-inflating part. The adhered part is coated with a seam sealant and sewed. The initial maximum pressure of the inflating part is 40 kPa or more when injecting a gas therein with an instant pressure of at least 10 bar, and the pressure after 6 seconds is 25 kPa or more. The side curtain airbag may optimize to apply the method of seam sealant coating and sewing on the adhered part constituting a boundary between the inflating part and the non-inflating part. Thus, it can keep the internal gas pressure of the airbag to the extent of protecting passengers safely at rollover.
摘要翻译： 公开了一种侧帘式安全气囊和包括该侧帘式安全气囊的气囊系统。 根据本发明的侧帘式气囊包括具有气体膨胀的充气部，支撑充气部的非充气部以及构成充气部与非充气部之间的边界的粘接部。 粘合部分涂有缝隙密封剂并进行缝合。 当以10巴的即时压力注入气体时，充气部的初始最大压力为40kPa以上，6秒以后的压力为25kPa以上。 侧帘式安全气囊可以优化，从而将缝合密封剂涂布和缝合的方法应用于构成充气部和非充气部之间的边界的粘接部。 因此，可以将气囊的内部气体压力保持在安全地保护乘客的过程中。
