Abstract

The airbag system 1 and 2 (a front seat-inflator double curtain system and a rear seat-inflator double curtain system) comprises an airbag being expanded at a side of a vehicle compartment by igniting the inflator 11, 12 based on a signal from a collision-detecting sensor in the event of a collision of the vehicle, wherein the airbag includes a front seat-protecting airbag 10 and a rear seat-protecting airbag 20, wherein the collision-detecting sensor includes at least a front seat-detecting sensor 14 for detecting a side impact occurred at a front seat and a rear seat-detecting sensor 24 for detecting a side impact occurred at a rear seat, and wherein the front seat-protecting airbag 10 is expanded when the front seat-detecting sensor 14 detects a side impact, the rear seat-protecting airbag 20 is expanded when the rear seat-detecting sensor 24 detects a side impact.

Claims

1. An airbag system comprising:

an airbag accommodated in a side of a vehicle body;

an inflator for supplying gas to the airbag; and

a collision-detecting sensor for detecting a collision of a vehicle, the airbag being expanded at a side of a vehicle compartment by igniting the inflator based on a signal from the collision-detecting sensor in the event of a collision of the vehicle,

wherein the airbag includes a front seat-protecting airbag and a rear seat-protecting airbag,

wherein the collision-detecting sensor includes at least a front seat-detecting sensor for detecting a side impact occurred at a front seat and a rear seat-detecting sensor for detecting a side impact occurred at a rear seat, and

wherein the front seat-protecting airbag is expanded when the front seat-detecting sensor detects a side impact, and the rear seat-protecting airbag is expanded when the rear seat-detecting sensor detects a side impact.

2. An airbag system comprising:

an airbag accommodated in a side of a vehicle body;

an inflator for supplying gas to the airbag; and

a collision-detecting sensor for detecting a collision of a vehicle, the airbag being expanded at a side of a vehicle compartment by igniting the inflator based on a signal from the collision-detecting sensor in the event of a collision of the vehicle,

wherein the airbag includes a front seat-protecting airbag, a middle seat-protecting airbag, and a rear seat-protecting airbag,

wherein the collision-detecting sensor includes at least a front seat-detecting sensor for detecting a side impact occurred at a front seat, a middle seat-detecting sensor for detecting a side impact occurred around a middle seat, and a rear seat-detecting sensor for detecting a side impact occurred at a rear seat, and

wherein the front seat-protecting airbag is expanded when the front seat-detecting sensor detects a side impact, the middle seat-protecting airbag is expanded when the middle seat-detecting sensor detects a side impact, and the rear seat-protecting airbag is expanded when the rear seat-detecting sensor detects a side impact.
