is embedded in the belt 142 a distance 146 from the centerline 144 the self centering air bag is fixedly attached to the belt 142 at its fixation point 112 shown in fig1 the self centering airbag 110 is fixed to the belt 142 so as to create an angle 130 between the self centering air bag centerline 114 and the horizontal centerline 156 of the belt 142 the footprint 118 of the self centering air bag 110 is chosen so that when the self centering air bag 110 is deployed the self centering air bag centerline 114 is located so as to provide the passenger with optimal protection in a crash event as shown in fig1 the self centering air bag 110 is generally covered by a durable fabric cover 148 that includes a tearseam 149 upon deployment of the self centering air bag 110 the pressure of the expanding self centering air bag causes the durable fabric cover 148 to separate along the tearseam 149 thus allowing the self centering air bag to deploy into its fully inflated state as shown in fig1 in order to ensure that when deployed the self centering air bag centerline 114 ends up in the desired location this will be referred to as u201c tuning u201d the air bag sculpturing is used to manufacture the self centering air bag sculpturing the self centering.
