Title:
VEHICLE AIRBAG DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/059987
Kind Code:
A1
Abstract:
Disclosed is a vehicle airbag device which is capable of starting airbag deployment sooner. A vehicle airbag device (10) is provided with an airbag (24), a first inflator (26A) for supplying a gas to the airbag (24), a second inflator (26B) for supplying to the airbag (24) a gas at a higher pressure than the pressure of the gas supplied to the first inflator (26A), and a control unit (14) for operating the first inflator (26A) and the second inflator (26B). At the time of a frontal collision of the vehicle, the control unit (14) determines the collision velocity before determining whether or not a passenger is wearing a seatbelt. If the collision velocity (V) is greater than or equal to a first threshold value (v1) and less than a second threshold value (v2), then said control unit (14) operates the first inflator (26A) to inflate the airbag (24) without determining whether the passenger is wearing a seatbelt. Consequently, by simplifying the processing function of the control unit (14), deployment of the airbag (24) can be started sooner.
