Airbag apparatus

Abstract

An airbag apparatus for a vehicle with three seat-rows includes a vehicle airbag having first and second sections independent from each other extending in the longitudinal direction. The second section includes a first chamber, a second chamber and one gas inlet for supply gas to the second section. The first and second chambers are separated from each other in the longitudinal direction with a space therebetween except upper ends thereof through which the first and second chambers directly communicate with each other. The first section, first chamber and second chamber extend continuously along an upper portion of a sidewall of the vehicle and are located at portions corresponding to the three seat-rows of the vehicle to protect the passengers in the three seat-rows, respectively.

1 . An airbag apparatus for a vehicle having a sidewall and at least three seat-rows arranged in a longitudinal direction of the vehicle, comprising:
 a vehicle airbag installed at an upper portion of the sidewall to be inflated downwardly in passenger-protection regions between passengers seated in three seat-rows and the sidewall of the vehicle for protecting the passengers upon a vehicle accident,   first and second sections defined in the vehicle airbag for dividing an inside of the vehicle airbag to two sections independent from each other in the longitudinal direction, and   two gas supplying devices attached to the vehicle airbag, one gas supplying device supplying gas to the first section and the other gas supplying device supplying gas to the second section simultaneously,   wherein said second section comprises a first chamber, a second chamber and one gas inlet for supply the gas to the second section, said first and second chambers being separated from each other in the longitudinal direction with a space therebetween except upper ends thereof through which the first and second chambers directly communicate with each other, and   said first section, said first chamber and said second chamber extend continuously along an upper portion of the sidewall of the vehicle and are located at portions corresponding to the three seat-rows of the vehicle to protect the passengers in the three seat-rows, respectively.   
   
   
       2 . An airbag apparatus according to  claim 1 , wherein said first section, said first chamber and said second chamber are rectangular and have a size substantially same. 
   
   
       3 . An airbag apparatus according to  claim 2 , wherein each of said first and second chambers has one inner area without partition. 
   
   
       4 . An airbag apparatus according to  claim 1 , wherein said one gas inlet is located at one of the first and second chambers adjacent to a portion where the first and second chambers communicate with each other.
