Abstract: A multifunction switching arrangement for an electronic transmission control which includes a button on a knob casing which can be moved in opposite circumferential directions and alternatively operates two switches in the assemblage which in turn causes an upshift or downshift of the transmission. When a button is advanced in an axial direction, a third switch is operated to activate or deactivate the transmission overdrive. in one embodiment only a single button is moved to operate all three switches, while in two other embodiments a separate push button in the end of the knob casing is used to control the third switch.

Abstract: An arrangement for forming an air bag deployment opening in a vinyl covered trim piece in which one or more hinged deployment door substrates are formed with an upwardly turned rim extending about the unhinged sides which exerts a second stage cutting pressure on the inside of a covering vinyl layer. A first stage piercing cutter panel is also hinged along the same side but inclined downwardly to be initially contacted by the inflating air bag. An array of piercing elements formed on the cutter panel are forced through the vinyl covering layer prior to movement of the door substrate panel to pierce the covering layer at the center and corners of the door pattern prior to progressive cutting by the door panel rim.
