Abstract

A passenger-seat airbag device for a vehicle includes an instrument panel for the vehicle, a windshield extending upwardly from the instrument panel, and an airbag installed in an upper surface of the instrument panel to be inflated between the windshield and an occupant. The airbag includes a first surface facing the windshield, a second surface facing the occupant, and an internal member connecting the first and second surfaces. When the airbag is fully inflated, a top of the first surface contacts the windshield, a rest of the first surface is separated from the windshield, and a part of the first surface under the top is pulled toward the second surface by the internal member so that the airbag has a concave depression extending toward the second surface.

Claims

1. A passenger-seat airbag device for a vehicle, comprising:

an instrument panel for the vehicle,

a windshield extending upwardly from the instrument panel, and

an airbag installed in an upper surface of the instrument panel to be inflated between the windshield and an occupant, said airbag including a first surface facing the windshield, a second surface facing the occupant, and an internal member situated in the airbag and connecting the first and second surfaces so that when the airbag is fully inflated, a top of the first surface contacts the windshield, a rest of the first surface is separated from the windshield, and a part of the first surface under the top is pulled toward the second surface by the internal member to thereby form a concave depression extending toward the second surface in the first surface.

2. A passenger-seat airbag device according to claim 1, wherein said internal member connecting the first surface and the second surface has sufficient strength so as not to break when the airbag is fully inflated.

3. A passenger-seat airbag device according to claim 2, wherein said internal member breaks when the occupant impacts the inflated airbag after the airbag is fully inflated.

4. A passenger-seat airbag device according to claim 3, wherein said internal member is gradually torn to absorb an impact applied to the airbag.

5. A passenger-seat airbag device according to claim 4, wherein said internal member is made of a fabric having two flaps connected to the first and second surfaces, and a middle portion between the two flaps, said middle portion being gradually torn when the occupant hits the airbag.
