Embodiment Construction

[0066] The side airbag device 10 according to the first embodiment of the present invention is used to protect a passenger from an impact applied to a side portion of a vehicle, which will now be described.

[0067] FIG. 3 shows the seat 11 viewed from the vehicle door side. The seat 11 has a seat portion 12 and a seat back 13 . As shown in FIGS. 3 and 5 , the side airbag device 10 is embedded in a side portion of a seat back 13 .

[0068] The side airbag device 10 has an inflator 17 for generating inflation gas and an airbag 18 covering the inflator 17 . The housing 19 of the inflator 17 is fixed to the frame (not shown) of the seat back 13 . The inflation gas that inflates the airbag 18 is sealed in the housing 19 . A plurality of gas discharge ports (nozzles) 20 for discharging inflation gas are formed in the lower portion of the housing 19 .

[0069] A sensor (not shown in the figure) is connected to the inflator 17 for detecting an impact applied to the side of the bo...

Abstract

A side airbag device (10) for protecting an occupant (P) from a side impact applied to a body (15). The inside of the airbag (18) is divided into an upper chamber and a lower chamber. A connecting portion (24) is formed by joining the inside surfaces of the airbag. The flow of the inflation gas is distributed to the upper chamber and the lower chamber by the connecting portion.

Description

technical field [0001] The present invention relates to a side air bag device, such as a vehicle body, which is operated to protect a passenger from an impact when an impact greater than a predetermined impact amount acts on the body of a vehicle, etc., and particularly relates to a device for protecting a passenger from an impact. Side airbags from body sidewall impacts. Background technique [0002] FIG. 1 shows a first prior art side airbag device 102 described in Japanese Patent Laid-Open No. 10-67297. The side airbag device 102 is provided on the side of the seat cushion 101 . The airbag 103 is divided into an upper airbag 103a and a lower airbag 103b by a partition 104 . When the airbag 103 is inflated, the lower airbag 103b is disposed next to the buttocks Ph of the passenger P. As shown in FIG. A pressure limiting valve 105 is installed inside the isolation 104 . With isolation 104 and pressure limiting valve 105, lower bladder 103b is inflated prior to upper bla...
