Vehicle air bag cover

A panel for an automotive vehicle comprising:

• a wall having an opening,
• an integral closure normally closing said opening and concealing a stored air bag before it is deployed through said opening in a crash,
• said wall and closure being formed of a relatively stiff, self-supporting, flexible material,
• said closure comprising first and second doors each connected to said wall by an integral, flexible hinge,
• said hinges being in spaced apart parallel relation and said doors being capable of swinging open on said hinges in response to the force of impact of the air bag thereagainst when the air bag inflates so that the inflating air bag may deploy through the opening,
• said hinges each being in the form of an open trough of arcuate cross-section free of sharp bends having a bottom portion formed in a smooth curve and also having smooth curved portions connecting into said wall and into the associated door, respectively,
• said hinges being adapted to absorb at least a portion of the force of impact of the inflating air bag and to relieve stress and resist breaking of said doors and separation of said doors from said wall,
• said hinges being of less thickness and greater flexibility than the portions of the wall and doors immediately adjacent thereto,
• and scrim strips embedded in said hinges to reinforce and strengthen said hinges.
