Abstract
An inflatable vehicle occupant protection device (14) includes a woven panel (41) comprising first and second side panels (40 and 42) positioned overlying each other. The side panels (40 and 42) are not coated or laminated on any surface. Stitching (58) extends through and interconnects the overlying first and second panels (40 and 42). A film layer (75) is laminated onto the woven panel (41) covering an outer surface of the woven panel and the stitching (58).

21. An inflatable vehicle occupant protection device comprising:
-
first and second panels of woven material positioned overlying each other, the second panel being configured to leave exposed portions of the first panel extending about a periphery of the first panel; stitching that extends through and interconnects the overlying first and second panels; a first film layer overlying the first panel and covering the stitching; and a second film layer overlying the second panel and covering the stitching, the second film layer also covering the exposed portions of the first panel.

22. An inflatable vehicle occupant protection device comprising:
-
first and second panels of woven material positioned overlying each other; stitching that extends through and interconnects the overlying first and second panels; a first film layer overlying the first panel and covering the stitching; and a second film layer overlying the second panel and covering the stitching, the first and second film layers comprising peripheral overlap portions that extend beyond the peripheries of the first and second panels, the peripheral overlap portions overlying each other and being laminated to each other to form a peripheral edge seal that helps block inflation fluid leakage from between the first and second panels.
