Abstract
A curtain airbag device for a car is provided. A fill hose formed with a plurality of gas discharge openings is installed within a cushion so that compressed gas generated from an inflator can be supplied into the cushion, and there is provided with a guide that guides the flow of the compressed gas in the fill hose to be bent toward the gas discharge openings of the fill hose with respect to the longitudinal direction of the fill hose, thereby smoothly emitting the compressed gas in the fill hose into the cushion via the gas discharge openings of the fill hose.
Claims4
A curtain airbag for a car, the curtain airbag comprising:
- a cushion configured to be installed in a car body, wherein the cushion is expandable between a passenger and the car when the internal pressure within the cushion increases;
- an inflator configured to supply compressed gas to the cushion so as to expand the cushion;
- a fill hose provided within the cushion and in communication with the inflator, wherein the fill hose is formed having a plurality of gas discharge openings configured to supply the compressed gas supplied by the inflator into the cushion;
- and
- a guide that guides the flow of the compressed gas in the fill hose to be bent toward the gas discharge openings of the fill hose with respect to a longitudinal direction of the fill hose,
- wherein the guide is provided as a bending region of the fill hose,
- wherein the guide is formed by bending the region where the gas discharge opening of the fill hose is formed, so that the compressed gas in the fill hose can be smoothly emitted through the gas discharge openings of the fill hose,
- wherein a shape of the bending region of the fill hose is maintained by a non-expanding area of the cushion, and
- wherein the non-expanding area of the cushion includes a first stopping portion positioned at an upper side of the bending region of the fill hose and a second stopping portion positioned at a side of the bending region of the fill hose.
