VEHICLE INSTRUMENT PANEL REINFORCEMENT AND PASSENGER SEAT AIRBAG DEVICE ATTACHMENT STRUCTURE EMPLOYING THE VEHICLE INSTRUMENT PANEL REINFORCEMENT

Vehicle instrument panel reinforcement and a passenger seat airbag device attachment structure employing the vehicle instrument panel reinforcement are provided that are capable of securing the strength and rigidity to support for example a reaction force imparted during deployment of a passenger seat airbag device, and are also capable of achieving a reduction in both cost and weight. Instrument panel reinforcement 10 formed with a quadrilateral shaped closed cross-section profile from an upper member 14 and a lower member 16 is disposed along the vehicle width direction inside a vehicle instrument panel 30. A circular cylinder shaped collar 72 is disposed inside a closed cross-section portion 29 of the upper member 14. A passenger seat airbag device 34 is fastened and fixed to the instrument panel reinforcement 10 by a bolt and weld nut, employing the collar 72.
