AIRBAG ARRANGEMENT FOR A MOTOR VEHICLE
First Claim
1. An airbag for a motor vehicle that can be inflated to protect a vehicle occupant, comprising:
- a covering that forms an interior space that can be filled with gas, wherein the covering comprises an inflow opening;
a contact region that is configured to contact a gas-conducting pipe that conducts gas through the inflow opening and into the interior space to inflate the airbag, wherein the contact region surrounds the inflow opening and encloses the gas-conducting pipe in a sealing manner along a circumferential direction of the gas-conducting pipe; and
a protective layer that is arranged to protect the covering from hot gas that fills the interior space of the covering, wherein the protective layer comprises at least one fastening region that connects the protective layer to the covering, wherein the at least one fastening region is connected to the contact region.

Abstract
An airbag can include a covering that surrounds an interior space that can be filled with gas, a gas-conducting pipe which is stretched longitudinally along a direction of extent, and a contact region of the covering that surrounds the inflow opening and encloses the gas-conducting pipe in a sealing manner along a circumferential direction of the gas-conducting pipe that encircles the direction of extent. A protective layer of the covering can be arranged, at least in some sections in the interior space of the covering, with respect to the gas-conducting pipe so that damage to the covering during filling of the interior space of the covering with hot gas can be prevented by the protective layer. At least one fastening region of the protective layer, via which the protective layer can be connected to the covering, can be connected to the contact region of the covering.

19. An airbag module, comprising:
-
a gas generator;
a gas-conducting pipe that conducts gas produced by the gas generator to an airbag;
wherein the airbag includes;
a covering that forms an interior space that can be filled with the gas, wherein the covering includes an inflow opening for receiving the gas produced by the gas generator into the interior space; and
