Airbag arrangement
First Claim
1. An airbag arrangement for a vehicle occupant support system, the airbag arrangement comprising:
- an airbag arranged on a side of a backrest of a vehicle seat in such a way that when inflated the airbag first extends in a direction of a vertical vehicle axis and then extends forward from the backrest in the direction of travel of the vehicle, the airbag comprising;
at least two separate inflatable chambers spaced apart with respect to the vertical vehicle axis, the inflatable chambers at least partially forming an intermediate space, each inflatable chamber extending forward from the backrest in the direction of travel and assigned to a body region of a vehicle occupant to support the vehicle occupant in the event of a side collision,wherein the chambers each comprise a section when the airbag is inflated that extends forward in the direction of travel in such a way that the airbag supports a vehicle occupant in the event that the vehicle occupant moves obliquely forward in the direction of travel, the section intercepting an associated body region of the vehicle occupant,wherein the chambers are connected to one another in a connecting region that permits an exchange of gas between the chambers,wherein an upper one of the chambers comprises a first section adjoining the connecting region, the first section located at a front of the upper chamber in the direction of travel and at a bottom of the upper chamber along the vertical vehicle axis,wherein a lower one of the chambers comprises a second section adjoining the first section, the second section located at a front of the lower chamber in the direction of travel and a top of the lower chamber along the vertical vehicle axis, andwherein the chambers are supported against one another via the first and second sections to minimize an intermediate space between the chambers.

Abstract
An airbag arrangement for a vehicle occupant restraint system includes an airbag on a side of a backrest of a vehicle seat that when inflated first extends substantially in a direction of a vertical vehicle axis and then forward from a backrest in a direction of travel of the vehicle. The airbag includes at least one inflatable chamber extending substantially forward from the backrest in the direction of travel and that is assigned to a body region of a vehicle occupant to support the vehicle occupant in a side collision. The at least one chamber is extended by a section that extends forward in the direction of travel when the airbag is inflated so that the airbag supports the vehicle occupant if vehicle occupant moves obliquely forward in the direction of travel because the section intercepts the associated body region of the vehicle occupant.

15. An airbag module configured to be located in a backrest of a vehicle seat, the module comprising:
-
a gas generator; an airbag configured to be inflated by gas supplied from the gas generator, wherein the airbag is configured to deploy vertically upward and then forward and wherein the airbag includes; at least two separate inflatable chambers spaced apart with respect to the vertical vehicle axis, the inflatable chambers at least partially forming an intermediate space, each inflatable chamber extending forward from the backrest in the direction of travel and assigned to a body region of a vehicle occupant to support the vehicle occupant in the event of a side collision, wherein the chambers each comprise a section when the airbag is inflated that extends forward in the direction of travel in such a way that the airbag supports a vehicle occupant in the event that the vehicle occupant moves obliquely forward in the direction of travel, the section intercepting an associated body region of the vehicle occupant, wherein the chambers are connected to one another in a connecting region that permits an exchange of gas between the chambers, wherein an upper one of the chambers comprises a first section adjoining the connecting region, the first section located at a front of the upper chamber in the direction of travel and at a bottom of the upper chamber along the vertical vehicle axis, wherein a lower one of the chambers comprises a second section adjoining the first section, the second section located at a front of the lower chamber in the direction of travel and a top of the lower chamber along the vertical vehicle axis, and wherein the chambers are supported against one another via the first and second sections to minimize an intermediate space between the chambers.
