Problems solved by technology

[0005] A disadvantage of conventional curtain airbags is that they are constructed so that gas flows into the curtain airbag from the rear pillar near the inflator, to the center pillar, and then to the front pillar
This configuration results in a difference in curtain airbag deployment time between the rear and front pillars

Embodiment Construction

[0013] refer to figure 1 and 2 A side curtain airbag system for an automobile includes a gas pipe 112 that supplies gas generated from an inflator 110 to a curtain airbag 114 . The gas pipe 112 may be a hose, a tube, an aluminum pipe, or a steel pipe, and is formed with a plurality of injection films 112 a to supply gas to the curtain airbag 114 . The gas injection film 112 a is formed where the gas pipe 112 and the curtain airbag 114 are connected.

[0014] Such as image 3 and 4 As shown, gas injection film 112a is placed over gas tube 112 and may be composed of the same material as gas tube 112 . The gas injection film 112a may be made of a thinner film relative to the thickness of the gas tube 112 (ie, the difference between the thicknesses of the outer diameter and inner diameter of the gas tube 112). The outer shape of the gas injection film 112a is circular, but may also be elliptical, polygonal, or other shapes. The groove 112b may be formed at the boundary of th...

Abstract

The present invention discloses a side curtain airbag for an automobile, which includes a gas tube formed with a plurality of gas spray films that are separated or ruptured using gas generated by an inflator. The gas tube is initially filled with gas having a predetermined pressure. When the air pump is used, and high pressure gas is sprayed into the gas tube, the high pressure gas separates or ruptures the plurality of gas injection films from the gas tube. The gas is charged into all parts of the curtain airbag, thereby uniformly inflating the curtain airbag, and also reducing the deployment time of the curtain airbag.

Description

technical field [0001] The invention relates to a side curtain airbag system. More particularly, the present invention relates to a side curtain airbag that deploys rapidly and uniformly in an automobile collision accident. Background technique [0002] Generally speaking, automobiles are equipped with various safety devices to protect occupants in the event of an automobile collision. Whether the occupant is a child or an adult, in a frontal or side collision, the airbag, as one of the car's installed devices, will protect the occupant's chest and head area from injury. [0003] Typically, the driver's airbag is stored in the center of the steering wheel and the front passenger's airbag is stored in the crash pad. To optimize occupant protection, an additional airbag is installed next to the inner left or right side of the seat, or along the roof side rails, thus protecting occupants from impact even in side collisions. [0004] The airbags placed along the side rails of...
