Inflatable airbag for a vehicle which is deployed in the event of an accident involving the vehicle to provide protection for an occupant of the vehicle includes a plurality of ribbons coupled together to define an enclosed, fluid-retaining space and a layer of film laminated on at least one of an outer side of the woven ribbons and an inner side of the ribbons. The ribbons may be made from polypropylene, polyethylene, polyester or polyamide and the layers of film may be made from polyethylene, polyurethane, polyester or polyamide. The ribbons and layers of film may be made of the same or different materials.

The invention claimed is: 1. An inflatable airbag for a vehicle which is deployed in the event of an accident involving the vehicle to provide protection for an occupant of the vehicle, comprising: a plurality of ribbons coupled together to define an enclosed, fluid-retaining space; and a layer of film laminated on at least one of an outer side of the woven ribbons and an inner side of the ribbons. 2. The airbag of claim 1, wherein the ribbons are made from polypropylene, polyethylene, polyester or polyamide and the layers of film are made from polyethylene, polyurethane, polyester or polyamide. 3. The airbag of claim 1, wherein said plurality of ribbons comprises a first set of ribbons oriented in a first direction and a second set of ribbons oriented in a second direction different than the first direction, said first and second sets of ribbons being attached together. 4. The airbag of claim 3, wherein said first and second sets of ribbons are woven together. 5. The airbag of claim 1, wherein said ribbons are formed in separate pieces, further comprising an elastomer arranged at seams at which said pieces are coupled together to form the space. 6. The method of claim 5, wherein the elastomer is polyurethane. 7. The method of claim 6, wherein the elastomer is part of the pieces of airbag material. 8. The airbag of claim 1, wherein said ribbons are coupled together to define a side curtain airbag. 9. The airbag of claim 1, wherein said ribbons are coupled together to define a knee airbag. 10. The airbag of claim 1, wherein said ribbons and said layers of film are made of different materials. 11. The airbag of claim 1, wherein a layer of film is laminated on both the outer side and the inner side of the ribbons. 12. A method for forming an inflatable airbag for a vehicle which is deployed in the event of an accident involving the vehicle to provide protection for an occupant of the vehicle, comprising: coupling a plurality of ribbons together to define an enclosed, fluid-retaining space; and laminating a layer of film on at least one of an outer side of the woven ribbons and an inner side of the ribbons. 13. The method of claim 12, wherein the plurality of ribbons comprises a first set of ribbons oriented in a first direction and a second set of ribbons oriented in a second direction different than the first direction, the step of coupling the ribbons together comprising weaving the first and second sets of ribbons together. 14. The method of claim 12, wherein the ribbons are formed in separate pieces, further comprising arranging an elastomer at seams at which the pieces are coupled together to form the space. 15. The method of claim 12, wherein a layer of film is laminated on both the outer side and the inner side of the woven ribbons. 16. A method for forming an inflatable airbag for a vehicle which is deployed in the event of an accident involving the vehicle to provide protection for an occupant of the vehicle, comprising: providing a plurality of pieces of airbag material, the pieces having substantially the same thickness and composition; and joining the pieces together at seams using an elastomer such that the elastomer constitutes a bonding agent for joining the pieces of material together and stress at the seams is distributed along the seams and possibly into the seams. 17. The method of claim 16, wherein the elastomer is polyurethane. 18. The method of claim 16, wherein the elastomer is part of the pieces of airbag material. 19. A method for forming an inflatable film airbag for a vehicle which is deployed in the event of an accident involving the vehicle to provide protection for an occupant of the vehicle, comprising: providing at least two uniaxially oriented films, each of the films being stretched in a single direction to provide the uniaxial orientation and each of the films having a different orientation direction such that the films are at a non-parallel angle to one another; and weakly laminating the films together, the airbag being made only from film. 20. The method of claim 19, wherein two films are provided and the orientation direction of the films is perpendicular to one another.
