Abstract
Abstract The invention relates to an airbag system for motor vehicles with an airbag and at least one associated gas generator for inflating the airbag in the event of an accident involving the vehicle. According to the invention, the airbag system is fixed on the vehicle where it can be moved at least in part away from the vehicle occupant. To this end, the airbag system is attached to the vehicle so that it can be translated, rotated, or tilted. Preferably it can be moved by the gases emerging from the gas generator after ignition thereof and is fixed on at least one plastically deformable element or spring element. The system according to the invention reduces the risk of injury to the occupant where at the time of inflation of the airbag the vehicle occupant is bending forward in the vehicle seat.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
143 words
An airbag system for use in a vehicle which protects an occupant of the vehicle in the event of an impact on the vehicle, the airbag system comprising: an airbag module comprising an airbag and a gas generator for inflating the airbag; and at least one plastically deformable members, which is U-shaped in cross-section, connected with the airbag module for restraining movement of the airbag module away from the vehicle occupant in the absence of either an impact force acting on the airbag system or ignition of the gas generator, wherein said at least one plastically deformable member is responsive to ignition of the gas generator for enabling at least a portion of the airbag module to translate away from the vehicle occupant, whereby the inflation of the airbag does not injure the vehicle occupant, and further preventing airbag recoil after such translation.
Claim 2
Dependent Claim
143 words
An airbag system for use in a vehicle which protects an occupant of the vehicle in the event of an impact on the vehicle, the airbag system comprising: an airbag module comprising an airbag and a gas generator for inflating the airbag; and at least one plastically deformable members, which is U-shaped in cross-section, connected with the airbag module for restraining movement of the airbag module away from the vehicle occupant in the absence of either an impact force acting on the airbag system or ignition of the gas generator, wherein said at least one plastically deformable member is responsive to ignition of the gas generator for enabling at least a portion of the airbag module to translate away from the vehicle occupant, whereby the inflation of the airbag does not injure the vehicle occupant, and further preventing airbag recoil after such translation.
Claim 3
Dependent Claim
54 words
The airbag system of claim 1 wherein the airbag module comprises a first end portion and a second end portion and wherein the at least one plastically deformable U-shaped member is attached to the first end portion and a hinge is attached to the second end portion to allow the airbag module to pivot.
Claim 4
Dependent Claim
14 words
The airbag system of claim 1 wherein the plastically deformable member comprises a ring.
Claim 5
Dependent Claim
18 words
The airbag system of claim 3 wherein the ring comprises slits whereby the ring is more easily deformed.
Claim 6
Dependent Claim
107 words
An airbag system for use in a vehicle which protects an occupant of the vehicle in the event of an impact on the vehicle, the airbag system comprising: an airbag; a gas generator for inflating the airbag; and at least one plastically deformable member, which is U-shaped in cross-section, connected with the airbag system and responsive to ignition of the gas generator for enabling at least a portion of the airbag system to translate away from the vehicle occupant, whereby the inflation of the airbag does not injure the vehicle occupant, and further preventing airbag recoil after such translation, wherein the plastically deformable member comprises a ring.
Claim 7
Dependent Claim
107 words
An airbag system for use in a vehicle which protects an occupant of the vehicle in the event of an impact on the vehicle, the airbag system comprising: an airbag; a gas generator for inflating the airbag; and at least one plastically deformable member, which is U-shaped in cross-section, connected with the airbag system and responsive to ignition of the gas generator for enabling at least a portion of the airbag system to translate away from the vehicle occupant, whereby the inflation of the airbag does not injure the vehicle occupant, and further preventing airbag recoil after such translation, wherein the plastically deformable member comprises a ring.
Claim 8
Dependent Claim
18 words
The airbag system of claim 5 wherein the ring comprises slits whereby the ring is more easily deformed.
Claim 9
Dependent Claim
125 words
An airbag system for use in a vehicle which protects an occupant of the vehicle in the event of an impact on the vehicle, the airbag system comprising: an airbag assembly comprising an airbag and a gas generator for inflating the airbag; and at least one plastically deformable member, which is U-shaped in cross-section, connected to the airbag assembly for restraining movement of the airbag assembly away from the vehicle occupant in the absence of either an impact force acting on the airbag system or ignition of the gas generator, wherein said at least one plastically deformable member is responsive to ignition of the gas generator for enabling the airbag assembly to translate away from the vehicle occupant and preventing airbag recoil after such translation.
Claim 10
Dependent Claim
125 words
An airbag system for use in a vehicle which protects an occupant of the vehicle in the event of an impact on the vehicle, the airbag system comprising: an airbag assembly comprising an airbag and a gas generator for inflating the airbag; and at least one plastically deformable member, which is U-shaped in cross-section, connected to the airbag assembly for restraining movement of the airbag assembly away from the vehicle occupant in the absence of either an impact force acting on the airbag system or ignition of the gas generator, wherein said at least one plastically deformable member is responsive to ignition of the gas generator for enabling the airbag assembly to translate away from the vehicle occupant and preventing airbag recoil after such translation.
Claim 11
Dependent Claim
37 words
The airbag system of claim 7 wherein the U-shaped member in cross-section comprises first and second legs, wherein, the first leg is supported in the airbag system and the second leg is connected to the airbag assembly.
Claim 12
Dependent Claim
40 words
The airbag system of claim 8 further comprising a cavity which houses the airbag assembly and the at least one plastically deformable member, wherein the first leg of the at least one plastically deformable member is supported in the cavity.
Claim 13
Dependent Claim
