Abstract

격벽에 의해 구분된 복수개의 연소실간의 가스 발생제의 연소 속도를 알맞게 조정하여, 만족할 만한 에어백의 팽창 특성을 얻을 수 있는 에어백용 인프레이터를 구성한다. 하우징(1)의 내부를 복수개의 연소실(6a-6c)로 구분하고, 점화기에 의해 제1연소실(6a)의 가스 발생제가 발화하면, 이 연소 가스를 하우징에 설치된 분기공(3)을 통해 에어백 내로 분출시키는 한편, 상기 제1연소실의 가스 발생제의 화염으로 다른 연소실(6b.6c)의 가스 발생제도 발화시켜서 이 연소 가스도 다른 분기공을 통해 에어백 내로 분출되도록 하여 이루어지는 에어백용 인프레이터에 있어서, 상기 제1연소실의 중심과 점화용 화염 방사공(9)의 중심을 통과하는 직선을 y축으로 하고, 상기 y축에 직교하며 상기 제1연소실의 중심을 통과하는 직선을 x축이라고 했을 때, 상기 제1연소실의 중심에 대한 제3상한 및 제4상한의 부분에 상기 제1연소실로부터 다른 연소실로의 화염 방사용 연통공(10)을 설치하도록 한다.By adjusting the combustion speed of the gas generating agent between the several combustion chambers separated by the partition, the inflator for airbags which can obtain the expansion characteristic of an airbag satisfactory is comprised. The interior of the housing 1 is divided into a plurality of combustion chambers 6a-6c, and when the gas generating agent of the first combustion chamber 6a is ignited by the igniter, this combustion gas is introduced into the air bag through the branch hole 3 provided in the housing. In the injector for airbags which ejects, the gas generator of another combustion chamber 6b.6c is ignited by the flame of the gas generating agent of a said 1st combustion chamber, and this combustion gas is also ejected into an airbag through another branch hole. When the straight line passing through the center of the first combustion chamber and the center of the ignition flame spinning hole 9 is the y axis, the straight line passing perpendicular to the y axis and passing through the center of the first combustion chamber is called the x axis. A flame radiating communication hole 10 from the first combustion chamber to the other combustion chamber is installed at portions of the third upper limit and the fourth upper limit with respect to the center of the first combustion chamber.

하우징의 내부를 복수개의 연소실로 나누고, 점화기에 의해 제1연소실의 가스 발생제가 발화하면, 이 연소 가스를 하우징에 설치된 분기공으로부터 에어백 내로 분출시키는 한편, 상기 제1연소실의 가스 발생제의 화염에 의해 다른 연소실의 가스 발생제도 발화시켜서 이 연소 가스도 별도의 분기공으로부터 에어백 내로 분출되도록 하여 이루어지는 에어백용 인프레이터에 있어서, 상기 제1연소실의 중심과 점화용 화염 방사공의 중심을 통과하는 직선을 y축으로 하고, 상기 y축에 직교하며 상기 제1연소실의 중심을 통과하는 직선을 x축이라고 했을때, 상기 제1연소실의 중심에 대한 제3상한 및 제4상한 부분에 상기 제1연소실로부터 다른 연소실로의 화염방사용 연통공을 설치한 것을 특징으로 하는 에어백용 인프레이터.When the inside of the housing is divided into a plurality of combustion chambers, and the gas generating agent of the first combustion chamber is ignited by the igniter, the combustion gas is ejected from the branch hole provided in the housing into the airbag, and the flame of the gas generating agent of the first combustion chamber is caused by the flame. An airbag injector in which a gas generator in another combustion chamber is also ignited so that this combustion gas is ejected from a separate branch hole into an airbag, wherein the y-axis is a straight line passing through the center of the first combustion chamber and the center of the ignition flame spinning hole. When a straight line passing perpendicular to the y axis and passing through the center of the first combustion chamber is referred to as the x axis, a combustion chamber that is different from the first combustion chamber to the third upper limit and the fourth upper limit with respect to the center of the first combustion chamber. Airbag inflator characterized by the installation of a flame discharge communication hole in the furnace. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
