1. An airbag comprising:
- a first, lateral portion of the airbag for being deployed in a predetermined direction toward a vehicle occupant;
a second, lateral portion of the airbag for being deployed in the predetermined direction toward the vehicle occupant, the lateral airbag portions being laterally spaced from each other transverse to the predetermined deployment direction; and
a gas flow path that extends between the laterally spaced first and second airbag portions at an intermediate position along the deployment direction so that respective internal spaces of the first and second lateral airbag portions are in communication with each other via the gas flow path to substantially equalize internal pressure of the first and second airbag portions for generally uniform expansion thereof,wherein the first and second airbag portions each include outer sides and inner sides, the inner sides having an open lateral gap therebetween that is outside the airbag and extends in the deployment direction along the inner sides and a connection between the inner sides for the gas flow path with the connection interrupting and extending across the open lateral gap so that gas flows through the gas flow path across the open lateral gap between the inner sides of the airbag portions.

Abstract
An airbag and airbag device are provided wherein the left airbag section and right airbag section both expand generally uniformly. An airbag comprises a right airbag section which expands at the right side ahead of the passenger, and a left airbag section which expands at the left side ahead of the passenger. Openings are provided on the facing faces of the right airbag section and the left airbag section at a portion partway along the direction of expansion, the perimeter portions of the openings and are sewn together. The inner space of the right airbag section and the left airbag section communicate through the openings.

9. An airbag device including an airbag for being deployed in a passenger compartment of a vehicle, the airbag device comprising:
-
a first portion of the airbag; a second portion of the airbag; a common rear chamber of the airbag connected to the first and second airbag portions; an inflator disposed inside the common rear chamber with the airbag inflated, the inflator being for providing gas into the rear chamber and then into the connected first and second airbag portion; and a connection between the first and second airbag portions to form a gas flow path therebetween with the connection and gas flow path being spaced from the airbag rear chamber. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
