• a first membrane having an interior portion;
• a second membrane having an interior portion, the first and second membranes attachable to form first, second, and third inflatable protection zones between the interior portions of the first and second membranes and to form two connecting zones between each of the inflatable protection zones;
• an inflation channel configured to receive pressurized gas from a source of pressurized gas, the gas being directed into the inflatable protection zones by a gas guide;
• and
• at least one communication channel disposed within one of the connecting zones to communicate the pressurized gas from one inflation zone to another inflation zone.

An airbag cushion, having a top and a bottom, for protecting an occupant of a vehicle, the vehicle have pillars A through D, the curtain comprising:

• a first connecting zone between the first protection zone and the second protection zone;
• a second connecting zone between the second protection zone and the third protection zone;
• an inflation channel for receiving pressurized gas from a source of pressurized gas, the inflation channel directing the pressurized gas into each of the protecting zones;
• a first communication channel disposed within the first connecting zone, the first communication channel communicating the pressurized gas between the first protection zone and the second protection zone;
• and
• a second communication channel disposed within the second connecting zone, the second communication channel communicating the pressurized gas between the second inflatable protection zone and the third inflatable protection zone.
