Abstract: A vehicle interior trim system such as an instrument panel or a door panel includes a panel substrate defining a deployment aperture. An inflatable device such as an air bag is adapted to deploy through the aperture during a crash. A natural, tanned leather skin covers the substrate, wherein the skin has a tear seam corresponding to the aperture on a hidden surface of the skin. An aperture door may be fitted within the deployment aperture which is adapted to open against the skin in response to deployment of the inflatable device. The tear seam is comprised of a region on the hidden surface of the skin having a disrupted fiber matrix from exposure to an alkaline solution such as ammonia, bleach, sodium tetraborate, sodium hydroxide, sodium bicarbonate, trisodium phosphate, potassium hydroxide, and potassium carbonate.

Abstract: A processing device and a method for processing structure data representing a physical structure are disclosed to obtain information about physical properties of the physical structure faster and with high quality and accuracy. The processing device for processing structure data representing a physical structure comprises an obtainer module for obtaining structure data representing a physical structure; a parts defining module for subdividing said structure data into at least two parts including a connection part and a material part; a meshing module for generating a mesh model approximating said physical structure by transforming said connection part and said material part into mesh elements having different sizes, wherein the mesh element sizes of said connection part are smaller than the mesh element sizes of said material part; and a processing module for processing said mesh model to estimate physical properties of said physical structure.
