Bag for an airbag for a vehicle

A bag for a vehicle air bag device comprising:

• an occupant-associated panel and an inflator-associated panel joined together along their peripheral edges to form said bag which is inflatable into a three-dimensional form;
• said inflator-associated panel having an inflator opening for attaching an inflator:
• a flow regulator for diverting a gas flow from the inflator toward an outer periphery of said bag;
• said flow regulator including a sheet which covers said inflator opening;
• said sheet having a middle portion bulging toward said inflator-associated panel during inflation of said bag;
• said sheet having joined portions at a peripheral edge thereof joined at at least two places to said inflator-associated panel to form define diversion openings defined by portions of the peripheral edge of said sheet other than at said joined portions and said inflator-associated panel forms openings through which said gas flow is diverted;
• tethers connecting said occupant-associated panel and said inflator-associated panel to prevent the spacing between the said occupant-associated panel and said inflator-associated panel from exceeding a predetermined length;
• and
• said tethers being disposed at positions not obstructing the flow of gas diverted by said flow regulator.

• an occupant-associated panel and an inflator-associated panel joined together along their peripheral edges form said bag which is inflatable into a three-dimensional form;
• said inflator-associated panel having an inflator opening for attaching an inflator;
• a flow regulator freely displaceable away from the inflator a predetermined distance in a direction toward an occupant for diverting a gas flow from the inflator toward a periphery of the bag throughout a period of gas production by said inflator;
• said flow regulator having diversion openings facing sideways in opposite directions so that the gas is diverted in two mutually opposite directions toward an outer periphery of said bag;
• a first pair of opposed sides of said bag being folded in said gas spouting direction and a second pair of opposed sides being folded in the direction orthogonal to said gas spouting direction;
• and
• the folding of said first pair of sides providing greater resistance to deployment than the folding of said second pair of sides.

• and
• said second pair of sides being folded first in a bellows fashion and then said first pair of sides being folded in a reverse roll fashion such that the folding of said first pair of sides provides greater resistance to deployment than the folding of said second pair of sides.
