Side impact air bag system
First Claim
1. A side impact air bag system having a bag inflating between a side of a vehicle and a passenger by a gas blown out from a gas generating device, said bag comprising:
- a first portion facing an abdomen portion of said passenger when inflated;
a second portion facing a chest portion of said passenger when inflated, said second portion being connected to said first portion;
gas flow adjusting means for allowing flow of the gas from said first portion into said second portion when the pressure of said gas blowing into said first portion reaches a predetermined pressure;
an inflation portion contained within said first portion prior to the inflation of the bag and deployed in a downward direction when the bag is inflated; and
second gas glow adjusting means for allowing flow of the gas from said first portion into said inflating portion when the pressure of said gas blowing into said first portion reaches the predetermined pressure.

Abstract
In a side impact air bag system having a bag comprising a main body, an upper inflation unit, and a lower inflation unit, the boundaries of the main body and the upper inflation unit and the lower inflation unit are joined and temporally sewn by sewn portions. The main body is inflated without having the upper and lower units inflated until the blowing gas from an inflator into the bag reaches a pressure above a predetermined pressure, and when the pressure inside the bag reaches the pressure above the predetermined pressure, the sewn portions are separated therefrom to flow gas into the upper and lower inflation units to deploy the upper and lower inflation units. Thus, the bag is positively inflated in a narrow space between a passenger and a vehicle without excessively increasing impact against a chest portion of the passenger.

15. A side impact air bag system having a bag that inflates between a side of a vehicle and a passenger by a gas blown out from a gas generating device, said bag comprising:
-
a first portion facing an abdomen portion of said passenger when inflated; more than one second portions connected to said first portion and facing areas of said passenger other than said abdomen portion when inflated; and gas flow adjusting means corresponding to each of said second portions for enabling gas flow from said first portion thereto based on whether pressure within said first portion reaches a predetermined threshold.

16. A side impact air bag system, comprising:
-
an inflator which generates gas; and a bag which includes; a first portion which protects an abdomen portion of a passenger inside a vehicle when inflated, said first portion being connected to said inflator; a second portion which protects a chest portion of the passenger when inflated, said second portion begin connected to said first portion; a gas flow adjusting unit which prohibits flow of gas from said first portion to said second portion until a pressure inside said first portion reaches a predetermined values; an inflation portion contained within said first portion prior to the inflation of the bag and deployed in a downward direction when the bag is inflated; and second gas flow adjusting means for allowing flow of the gas from said first portion into said inflating portion when the pressure of said gas blowing into said first portion reaches the predetermined pressure. - View Dependent Claims (17, 18, 19)

20. A side impact air bag system having a bag inflating between a side of a vehicle and a passenger by a gas blown out from a gas generating device, said bag comprising:
-
a first portion facing an abdomen portion of said passenger when inflated; a second portion facing a chest portion of said passenger when inflated, said second portion being connected to said first portion; and gas flow adjusting means for allowing flow of the gas from said first portion into said second portion when the pressure of said gas blowing into said first portion reaches a predetermined pressure, wherein said gas flow adjusting means includes an inner bag having a shape corresponding to said first portion, said inner bag being disposed in said first portion sand formed to rupture when the pressure of said gas in said first portion reaches the predetermined pressure. - View Dependent Claims (21)
