Abstract
Abstract A cover arrangement is disclosed for an air bag which is arranged in a motor vehicle and is automatically inflated to form an impact cushion for an occupant in the event of an accident. The cover arrangement includes a covering protecting the air bag being torn open at intended tearing lines. Provision is made for the covering to be constructed as a support of a membrane switch arrangement which, for its safety during inflation of the air bag and during the tearing open of the covering thus caused, is connected to a cladding of the covering made of leather or similar material so as to be resistant to tearing.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
189 words
Cover arrangement for an airbag which is folded and accommodated in a receiving compartment of a motor vehicle, comprising: a covering disposed to cover an automatically inflatable airbag disposed in the receiving compartment, said covering having predetermined tear lines along which the covering tears open in the event of inflation of the airbag; a decorative cladding of tear-resistant material disposed on a vehicle occupant side of the covering, said cladding being slotted adjacent the tear lines of the covering when in an in use storage position of the airbag and covering; and a membrane switch which is actuable by a vehicle occupant to operate a vehicle horn; wherein the covering is constructed as a support for the membrane switch; wherein the membrane switch is connected to the cladding by sewing so as to be tear resistant to thereby protect the safety of vehicle passengers by securing the membrane switch against detachment from the cladding during inflation of the airbag and tearing open of the covering; and wherein a relatively easily tearable film layer, which covers the intended tear lines in one piece, is arranged over the membrane switch arrangement.
Claim 2
Dependent Claim
189 words
Cover arrangement for an airbag which is folded and accommodated in a receiving compartment of a motor vehicle, comprising: a covering disposed to cover an automatically inflatable airbag disposed in the receiving compartment, said covering having predetermined tear lines along which the covering tears open in the event of inflation of the airbag; a decorative cladding of tear-resistant material disposed on a vehicle occupant side of the covering, said cladding being slotted adjacent the tear lines of the covering when in an in use storage position of the airbag and covering; and a membrane switch which is actuable by a vehicle occupant to operate a vehicle horn; wherein the covering is constructed as a support for the membrane switch; wherein the membrane switch is connected to the cladding by sewing so as to be tear resistant to thereby protect the safety of vehicle passengers by securing the membrane switch against detachment from the cladding during inflation of the airbag and tearing open of the covering; and wherein a relatively easily tearable film layer, which covers the intended tear lines in one piece, is arranged over the membrane switch arrangement.
Claim 3
Dependent Claim
206 words
Cover arrangement for an airbag which is folded and accommodated in a receiving compartment of a motor vehicle, comprising: a covering disposed to cover an automatically inflatable airbag disposed in the receiving compartment, said covering having predetermined tear lines along which the covering tears open in the event of inflation of the airbag; a decorative cladding of tear-resistant material disposed on a vehicle occupant side of the covering, said cladding being slotted adjacent the tear lines of the covering when in an in use storage position of the airbag and covering; and a membrane switch which is actuable by a vehicle occupant to operate a vehicle horn; wherein the covering is constructed as a support for the membrane switch; wherein the membrane switch is connected to the cladding by sewing so as to be tear resistant to thereby protect the safety of vehicle passengers by securing the membrane switch against detachment from the cladding during inflation of the airbag and tearing open of the covering; wherein the cladding is cut away in the region of actuating areas of the membrane switch arrangement; and wherein a relatively easily tearable film layer, which covers the intended tear lines in one piece, is arranged over the membrane switch arrangement.
Claim 4
Dependent Claim
