Abstract
Abstract In a side impact air bag system, a bag is formed of a main body opposing an abdomen portion of a passenger and an upper inflation unit opposing a chest portion of the passenger, a tip portion in the longitudinal direction of the upper inflation unit is deleted and a connection of a gas intake portion to an inflator is shortened to reduce a length of the upper inflation unit than the length of the main body. This reduces the length of the upper inflation unit to be shorter than the main body when the bag is inflated to relax the shock to the chest portion of the passenger when the bag is inflated, thereby positively inflating the bag in the narrow space between the vehicle body and the passenger's seat without excessively increasing the shock to the chest portion of the passenger.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
95 words
A side impact air bag system having an air bag inflated between the side of a vehicle and a passenger by a gas blown out from a gas generating device, said air bag comprising: a first portion opposing an abdomen portion of the passenger when inflated; and a second portion opposing a chest portion of the passenger when inflated; wherein a width in a lateral direction of vehicle at a boundary of said first portion and said second portion is narrower than a width in the lateral direction of the vehicle in said first portion.
Claim 2
Dependent Claim
95 words
A side impact air bag system having an air bag inflated between the side of a vehicle and a passenger by a gas blown out from a gas generating device, said air bag comprising: a first portion opposing an abdomen portion of the passenger when inflated; and a second portion opposing a chest portion of the passenger when inflated; wherein a width in a lateral direction of vehicle at a boundary of said first portion and said second portion is narrower than a width in the lateral direction of the vehicle in said first portion.
Claim 3
Dependent Claim
29 words
The side impact air bag system of claim 1, wherein said air bag includes a regulating member for regulating in a lateral direction of the vehicle at said boundary.
Claim 4
Dependent Claim
58 words
The side impact air bag system of claim 1, wherein said air bag includes a gas intake portion for suppressing diffusion of the gas blown out from said gas generating device for connecting said air bag and said gas generating device, said gas intake portion being formed as a passage having a predetermined height and a predetermined length.
Claim 5
Dependent Claim
32 words
The side impact air bag system of claim 3, wherein said gas intake portion has a narrowed portion for restricting a flow of the gas blown out from said gas generating device.
Claim 6
Dependent Claim
22 words
The side impact air bag system of claim 3, wherein said predetermined height is shorter than a length of the generating device.
Claim 7
Dependent Claim
25 words
The side impact air bag system of claim 3, wherein said predetermined height is substantially the same as a length of the gas generating device.
Claim 8
Dependent Claim
89 words
A side impact air bag system having an air bag inflated between the side of a vehicle and a passenger by a gas blown out from a gas generating device, said air bag comprising: a first portion opposing an abdomen portion of the passenger when inflated; and a second portion opposing a chest portion of the passenger when inflated; wherein a width in a lateral direction of a vehicle in said second portion is narrower than a width in the lateral direction of the vehicle in said first portion.
Claim 9
Dependent Claim
89 words
A side impact air bag system having an air bag inflated between the side of a vehicle and a passenger by a gas blown out from a gas generating device, said air bag comprising: a first portion opposing an abdomen portion of the passenger when inflated; and a second portion opposing a chest portion of the passenger when inflated; wherein a width in a lateral direction of a vehicle in said second portion is narrower than a width in the lateral direction of the vehicle in said first portion.
Claim 10
Dependent Claim
65 words
The side impact air bag system of claim 7, wherein an upper portion of said second portion at a side away from said gas generating device in a longitudinal direction of the vehicle is shifted towards said gas generating device by a predetermined length relative to an end of said first portion at a side away from said gas generating device in the longitudinal direction.
Claim 11
Dependent Claim
32 words
The side impact air bag system of claim 7, wherein said air bag includes a regulating member for regulating a width in the lateral direction of the vehicle at said second portion.
Claim 12
Dependent Claim
58 words
The side impact air bag system of claim 7, wherein said air bag includes a gas intake portion for suppressing diffusion of the gas blown out from said gas generating device for connecting said air bag and said gas intake portion, said gas intake portion being formed as a passage having a predetermined height and a predetermined length.
Claim 13
Dependent Claim
32 words
The side impact air bag system of claim 10, wherein said gas intake portion includes a narrowed portion for restricting a flow of the gas blown out from said gas generating device.
Claim 14
Dependent Claim
23 words
The side impact air bag system of claim 10, wherein said predetermined height is shorter than a length of the gas generating device.
Claim 15
Dependent Claim
25 words
The side impact air bag system of claim 10, wherein said predetermined height is substantially the same as a length of the gas generating device.
