Abstract: A vehicle interior panel includes a foam layer formed from a liquid foam precursor between a substrate and a visible decorative skin layer that has perforations formed therethrough. In some cases, the perforations are associated with a line of stitching sewn into and through the skin layer. A sealing film is located beneath the skin layer in the perforated region to prevent the liquid foam precursor from leaking through the perforations during foam formation. The sealing film extends beyond the perforated region and into a non-perforated region, in some cases extending substantially over the entire back side of the skin layer. In this manner, the edges of the sealing film do not cause visual blemishes on the visible surface of the decorative skin layer over time.

Abstract: A motor vehicle trim assembly includes a plastic outer trim panel having an opening, a door for closing the opening, an inner trim panel for storing an uninflated air bag curtain, a hinge for the door and a latch for holding the door in its closed position yet still allow deployment of the air bag curtain through the opening in the outer trim panel. Both the door and the hinge comprise a single injection molded part. The assembly preferably includes a lock for locking the door in its closed position yet also allow deployment of the air bag curtain. The inner trim panel, the latch and the lock all comprise a single injection molded part. The inner trim panel has a conduit portion integrally formed with a solid base wall portion which receives and retains the uninflated air bag curtain as well as an inflator of the system. A gas channel defined by the conduit portion may conduct fluids or pass solid objects such as electric wires through the inner trim panel.
