Inflatable airbag with overlapping chamber

A side-impact inflatable airbag system, comprising:

• a first inflatable cushion shaped to provide impact protection for a thorax and pelvic region of a projected position of a vehicular occupant:
• a second inflatable cushion inflatable independent of the first inflatable cushion, the second inflatable cushion shaped to provide impact protection for the pelvic region of the projected position of the occupant and located adjacent a side of the first inflatable cushion furthest away from the projected position of the occupant;
• and
• an inflator inflator assembly positioned within the side-impact system comprising a gas guide with a tapered cylindrical body wall, the gas guide intersects both the first inflatable cushion and the second inflatable cushion, wherein the gas guide comprises at least one outlet opening in the tapered cylindrical body all positioned within the first inflatable cushion, wherein a seal separates the first inflatable cushion and the second inflatable cushion leaving a small space through which the gas guide projects, wherein once the gas guide is in position, the first cushion and the second cushion are sealed off so that inflation gas may not pass between the two cushions and, wherein the inflator is constructed to inflate the second inflatable cushion at a higher pressure than the first inflatable cushion;
• and
• a zero-length tether that controls width of the first inflatable cushion when inflated.

A side-impact inflatable airbag system, comprising:

• a first inflatable cushion for providing impact protection for a thorax and pelvic region of a vehicular occupant:
• a second inflatable cushion for providing impact protection for the pelvic region of the occupant, the second cushion for providing impact protection inflates independent of the first cushion for providing impact protection;
• and
• an inflator inflator assembly positioned within the airbag system comprising a gas guide with a tapered cylindrical body wall, the gas guide intersects both the first inflatable cushion and the second inflatable cushion, wherein the gas guide comprises at least one outlet opening in the tapered cylindrical body wall positioned within the first inflatable cushion, wherein a seal separates the first inflatable cushion and the second inflatable cushion leaving a small space through which the gas guide projects, wherein once the gas guide is in position, the first cushion and the second cushion are sealed off so that inflation gas may not pass between the two cushions;
• wherein the first inflatable cushion includes a diffuser hood that initially directs inflation gas toward the portion of the first inflatable cushion adjacent the second inflatable cushion.
