    摘要: An apparatus for deploying an air bag through an automotive dash panel includes an air bag door integrally formed in the panel and defined by a door perimeter including a frangible edge of reduced cross section. A dispenser supports the air bag behind the door. A metal reaction plate is positioned between the air bag and the door. When the air bag inflates, it forces the reaction plate to bend around a horizontal hinge line. As the reaction plate pivots it concentrates inflation force along a lower portion of the frangible door edge. This helps to predictably separate the door from the dash panel by tearing along the lower door edge and allowing the tear to propagate up two side edges. In one embodiment, the tear also propagates across an upper edge to completely separate the door from the panel. At least one, and preferably two or three tethers limit how far the door can travel during air bag inflation. A stop member may be included to limit reaction plate bending. After deployment, the reaction plate remains in a position that prevents the door from returning to its original position. A retaining structure may be included to preclude at least a portion of the air bag door from tearing free of the vehicle panel. A hinge may be embedded in the panel in a position spanning a portion of the door perimeter. A hollow channel may be formed into the panel along the frangible marginal edge to create a substantial strength differential with the door perimeter to promote bending along the hinge and/or to help confine tearing to the frangible marginal edge during air bag deployment.

    摘要: A vehicle interior part such as a glove box door or console door and its method of manufacture includes an outer shell backed by foam material which is bonded to a mold insert that reinforces the part and defines an exposed back. The insert includes a peripheral edge spaced with respect to a continuously formed raw peripheral edge of the shell and further includes a flange portion that is post formed so as to be bonded to and located in a net out relationship with the raw edge to define a finished surface appearance. The door is formed by a process that includes the steps of providing a composite plastic structure having a molded shell and foam component with an insert located in spaced relationship with respect to the shell to define a foamed cavity with a raw edge of foam and shell around the periphery of the composite member; providing a post formed flange on the insert and loading the shell, foam and insert components into a female nest; and heat die post forming of the flange to upset it into net out overlying relationship with both the raw edge of the shell and the exposed edge of foam formed in the composite part so as to produce a finished exterior surface on the composite part.
