Inflatable side curtain
First Claim
1. Apparatus for helping to protect an occupant of a vehicle that has a side structure and a roof, said 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; and
an inflation fluid source that provides inflation fluid for inflating said inflatable vehicle occupant protection device;
said inflatable vehicle occupant protection device comprising a pair of overlying panels having overlapping portions that are secured together at points of connection;
said inflatable vehicle occupant protection device including first and second points of connection spaced vertically apart from each other and positioned along a first straight line that extends between said first and second points of connection, said inflatable vehicle occupant protection device being free from points of connection that lie along said first straight line between said first and second points of connection;
said inflatable vehicle occupant protection device including third and fourth points of connection spaced horizontally apart from each other and positioned along a second straight line that extends between said third and fourth points of connection, said inflatable vehicle occupant protection device being free from points of connection that lie along said second straight line between said third and fourth points of connection, said second straight line extending transverse to said first straight line, said first and second straight lines intersecting at a location between said first and second points of connection and between said third and fourth points of connection.

Abstract
Apparatus (10) for helping to protect an occupant of a vehicle (12) which has a side structure (16) and a roof (18) comprises an inflatable vehicle occupant protection device (14). The inflatable vehicle occupant protection device (14) is inflatable away from the vehicle roof (18) into a position between the side structure (16) of the vehicle (12) and a vehicle occupant. An inflation fluid source (24) provides inflation fluid for inflating the inflatable vehicle occupant protection device (14). The inflatable vehicle occupant protection device (14) comprises a pair of overlying panels (40, 42) having overlapping portions that are secured together at points of connection (60). First and second points of connection (70, 72) are spaced vertically apart from each other and positioned along a first straight line (74) that extends between the first and second points of connection. Third and fourth points of connection (80, 82) are spaced horizontally apart from each other and positioned along a second straight line (84) that extends between the third and fourth points of connection. The second straight line (84) extends transverse to the first straight line (74).
