The front plate (28') is provided with indicia capable of transmitting light therethrough, the indicia represent graphical information wherein light transmitted through the indicia causes an information-bearing image to be projected into the passenger compartment through a window (20') formed in a front panel (12') of the air bag cover. The light source (23') may be an emissive display such as an electroluminescent or thin film electroluminescent display.
