Inflatable curtain with two inflatable members
First Claim
1. Apparatus for helping to protect an occupant of a vehicle which has a side structure and a roof, said apparatus comprising:
- an inflatable curtain which is inflatable in a first direction away from the vehicle roof into a position between the side structure of the vehicle and a vehicle occupant, said inflatable curtain when inflating extending fore and aft in the vehicle along the side structure of the vehicle;
first and second inflatable members which connect said inflatable curtain to the vehicle; and
an inflation fluid source which provides inflation fluid for inflating said inflatable curtain and said first and second inflatable members;
said first and second inflatable members being inflatable to resist movement of said inflatable curtain away from the side structure of the vehicle when said inflatable curtain is inflated, said first and second inflatable members being generally tubular in shape and each having a given diameter and a given length when uninflated, said first inflatable member having a first end and an opposite second end, said first end being connected to said inflatable curtain at a location adjacent to a bottom edge and a forward edge of said inflatable curtain, said second end being connected to the vehicle at a first location, said second inflatable member also having a first end and an opposite second end, said first end of said second inflatable member being connected to said inflatable curtain at a location adjacent to said bottom edge and a rear edge of said inflatable curtain, said second edge of said second inflatable member being connected to the vehicle at a second location, said diameters of said first and second inflatable members increase and said lengths of said first and second inflatable members decrease when said first and second inflatable members when inflated resisting movement of said inflatable curtain away from the side structure of the vehicle, a first flexible elongated member connecting said first end of said first inflatable member to said inflatable curtain;
a first pulley connected to the vehicle at a third location, said first flexible elongated member being guided by said first pulley from said first end of said first inflatable member to said inflatable curtain;
a second flexible elongated member connecting said first end of said second inflatable member to said inflatable curtain; and
a second pulley connected to the vehicle at a fourth location, said second flexible elongated member being guided by said second pulley form said first end of said second inflatable member to said inflatable curtain.

Abstract
Apparatus (10) for helping to protect an occupant of a vehicle (12) which has a side structure (16) and a roof (28) comprises an inflatable curtain (14). The curtain (14) is inflatable in a first direction away from the roof into a position between the side structure of the vehicle and a vehicle occupant. The inflatable curtain (14) when inflated extends fore and aft in the vehicle (12) along the side structure (16) of the vehicle. First and second inflatable members (52 and 54) connect the inflatable curtain (14) to the vehicle (12). An inflation fluid source (24) provides inflation fluid for inflating the inflatable curtain (14) and the first and second inflatable members (52 and 54). The first and second inflatable members (52 and 54) are inflatable to resist movement of the inflatable curtain (14) away from the side structure (16) of the vehicle (12) when the inflatable curtain is inflated.
