  • Air bag for a vehicle air bag assembly and method of making the same
    Patent number: 5393092
    Abstract: A method of making air bags for vehicle air bag assemblies includes the step of forming a set of air bag panels. The set of panels includes a first panel with a perimetric edge and a second panel with a perimetric edge having an undulant fray-inhibiting contour. These panels are joined together to form a structure capable of being inflated to a predetermined three-dimensional configuration. Specifically, the perimetric edge of the first panel is joined to the perimetric edge of the second panel. Preferably, a plurality of second panels are die-cut with a die-board including a series of knives. Each knife has a shape corresponding to the desired shape of the second panel and the desired undulant fray-inhibiting contour of the panel's perimetric edge. The present invention also provides an air bag for a vehicle air bag assembly which includes a set of panels joined together to form a structure capable of being inflated into a three-dimensional shape.
