Inflatable side curtain
First Claim
1. Apparatus for helping to protect an occupant of a vehicle that has a side structure and a roof, the apparatus comprising:
- an inflatable vehicle occupant protection device that is inflatable away from the vehicle roof into a position between the side structure of the vehicle and a vehicle occupant, the inflatable vehicle occupant protection device comprising an inflatable main portion having at least one inflatable primary chamber and an inflatable secondary chamber, each primary chamber having an inflation fluid inlet and a plurality of inflation fluid outlets; and
an inflation fluid source that is actuatable to provide inflation fluid for inflating the inflatable vehicle occupant protection device, the inflation fluid source, when actuated, directing inflation fluid into the main portion to inflate the main portion, the inflation fluid inlet of each primary chamber directing inflation fluid from the inflation fluid source into the primary chamber, the inflation fluid outlets of each primary chamber directing inflation fluid from the primary chamber into the secondary chamber to inflate the secondary chamber.

Abstract
An apparatus (10) for helping to protect an occupant of a vehicle (12) that has a side structure (16) and a roof (18) includes an inflatable vehicle occupant protection device (14) inflatable away from the vehicle roof (18) into a position between the side structure (16) of the vehicle (12) and a vehicle occupant. The protection device (14) includes an inflatable main portion (62) having at least one inflatable primary chamber (110) and an inflatable secondary chamber (112). An inflation fluid source (30) is actuatable to provide inflation fluid for inflating the protection device (14). The inflation fluid source (30) when actuated directs inflation fluid into the main portion (62) to inflate the main portion (62). Inflation fluid inlets (152) of the primary chambers (110) direct inflation fluid from the inflation fluid source (30) into the primary chambers (110). Inflation fluid outlets (154, 156) of the primary chambers (110) direct inflation fluid from the primary chambers (110) into the secondary chamber (112) to inflate the secondary chamber (112).

18. Apparatus for helping to protect an occupant of a vehicle that has a side structure and a roof, the apparatus comprising:
-
an inflatable vehicle occupant protection device that is inflatable away from the vehicle roof into a position between the side structure of the vehicle and a vehicle occupant, the inflatable vehicle occupant protection device comprising an inflatable main portion having a plurality of inflatable primary chambers and an inflatable secondary chamber, each primary chamber having an inflation fluid inlet and a plurality of inflation fluid outlets; an inflatable front portion positioned forward of the main portion, the front portion including a forward edge, a rear edge, and a bottom edge, the front portion being in fluid communication with the main portion via an inflation fluid passage positioned near the bottom edge of the front portion; and an inflation fluid source that is actuatable to provide inflation fluid for inflating the inflatable vehicle occupant protection device, the inflation fluid source, when actuated, directing inflation fluid into the main portion to inflate the main portion, the inflation fluid inlet of each primary chamber directing inflation fluid from the inflation fluid source into the primary chamber, the inflation fluid outlets of each primary chamber directing inflation fluid from the primary chamber into the secondary chamber to inflate the secondary chamber, the inflation fluid passage directing inflation fluid from the secondary chamber to the front portion to inflate the front portion, the inflation fluid outlets being sized to maintain a predetermined inflation fluid pressure within the primary chambers while the secondary chamber inflates.
