Abstract: A three-dimensional airbag for a vehicle having a main panel having a generally elongated shape. The main panel includes a pair of generally symmetric first portions extending from opposite sides of a fold line and a pair of second portions. A subpanel is secured to the main panel to form a hollow body. The first portions of the main panel are joined to each other along their edges. The edges of the second portions are secured to the edge of the subpanel to close the open front end of the hollow body to form an air bag. The air bag may further include at least one of a baffle for controlling the flow of air within the bag during inflation and a tether assembly for controlling the opening of the air bag.
