Embodiment Construction

[0051] Embodiments of the present invention will be described below with reference to the accompanying drawings.

[0052] figure 1 It is a sectional view of the airbag and the airbag device in the first embodiment, and Fig. 2 is an exploded perspective view of the airbag and the airbag device, image 3 FIG. 4 is a plan view of the airbag, and FIG. 4 is a cross-sectional view illustrating the function of the airbag. And Fig. 4 (a) shows the state that airbag blocks occupant's instant before inflating to the maximum or shortly after this instant, Fig. 4 (b) shows the state after a period of time.

[0053] In this embodiment, the airbag 10 is an airbag for a driver's seat of a vehicle.

[0054] The airbag 10 includes a front panel 12 constituting the face facing the occupant, a rear panel 14 constituting the outer surface (rear surface) on the opposite side to the occupant facing surface, a first inner panel 22A and a second inner panel dividing the interior of the airbag 10 . ...

Abstract

Provided is an air bag capable of receiving an occupant in a wide area of the occupant confronting surface at the initial stage of inflation and an air bag device equipped with this air bag. The inside of the air bag 10 is partitioned into a radiating direction chamber 1 extending in the air bag radiating direction along a front panel 12, a central chamber 2 on the rear side of the central part of the air bag, and a peripheral chamber 3 at the periphery of the central chamber 2. The central chamber 2 and the radiating direction chamber 1 are in communication through communication holes 22c and 22e. A communication holer 22d to put the radiating direction chamber 1 in communication with the peripheral chamber 3 is provided at the forefront of each radiating direction cell 1b of the radiating direction chamber 1. From an inflator 36, gas is jetted into the central chamber 2 and is introduced to the radiating direction chamber 1 from the central chamber 2, and the radiating direction chamber 1 is inflated and spread in the air bag radiating direction. Then the gas flows out to the peripheral chamber 3 from the forefront of each radiating direction cell 1b, and the peripheral chamber 3 is inflated.

Description

technical field [0001] The present invention relates to an airbag that inflates against a vehicle occupant and the like to protect the vehicle occupant and an airbag device including the airbag, and particularly relates to an airbag and an airbag device suitable for a driver's seat. Background technique [0002] An airbag device for a driver's seat of an automobile includes an airbag, a holder for holding the airbag on a steering wheel, an inflator (gas generator) for inflating the airbag, and a unit cover attached to the holder to cover the folded airbag. When the automobile collides, the airbag squeezes the cover of the assembly and expands toward the front side of the steering wheel (the side of the driver's seat occupant), thereby protecting the driver's seat occupant. [0003] U.S. Patent No. 6,086,092 describes an airbag in which an inner airbag is disposed between the central portion of the occupant-facing surface of the outer airbag constituting the airbag casing and...
