AI Technical Summary
Technical Problem
Curtain airbags face challenges in deploying smoothly due to limitations in gas ejection pressure and capacity, leading to incomplete inflation and potential damage from high-pressure gas, necessitating the use of large-capacity inflators.
Method used
A curtain airbag design featuring multiple independent inflatable inner cushions within an outer cushion, each equipped with an inflator, guided by a gas-ejecting pocket, allowing for efficient inflation with low gas pressure, and utilizing a low-capacity inflator.
Benefits of technology
Ensures uniform and rapid inflation of the airbag cushion, providing comprehensive occupant protection without the need for high-pressure inflators, adaptable to various vehicle structures.

Abstract
The present invention relates to a curtain airbag device capable of smoothly inflating an airbag cushion even with a low gas ejection pressure of an inflator. A curtain airbag device according to one embodiment of the present invention comprises: an inflatable outer cushion provided along the front-rear direction of the vehicle on the upper side of a pillar constituting the vehicle; a plurality of independent inflatable inner cushions fixed at spaced apart from each other along the front-rear direction of the vehicle on the inner side of the outer cushion; and an inflator disposed inside each of the plurality of inner cushions to inject gas into the interior of the inner cushions so that the inner cushions are inflated by the generation of gas.
