An improved airbag design (10) has a defined gas pressure release area (14) located in the perimeter or outer seam region (12) of the airbag. The bag includes an extended area (16) that protrudes from the seam location. In this region, between the parallel portions of the seal or seam, there is no seal or seam present. The absence of the seal or seam in this region and the configuration of the seal or seam provides a controlled pressure release vent area (14). Once the vent region is opened, it allows pressurized gas from within the bag to vent at a given rate. Hollow core regions (22) or cavities within an air bag (20) form non-pressurized compartments located within the bag cavity that desirably decrease the volume of gas required to completely fill the bag. The presence of these compartments also decreases the time that it takes to fully pressurize the airbag in order to provide the desired cushioning effect.
