Abstract: A method, apparatus, and article of manufacture provide the ability to construct an optimal parameterization for a discrete surface patch. A three-dimensional image having a surface is selected. An initial parameterization of the surface onto a two-dimensional plane is constructed. A distortion of the initial parameterization is measured. A length parameter, an area parameter, and an angle parameter are specified. The initial parameterization is then optimized through a discrete deformation of a parameter domain that minimizes the distortion based on the length, area, and angle parameter.

Abstract: A vehicle seat has a seat member and a back rest connected to the seat member. The seat member and the back rest have an upholstery cover. An airbag module is mounted within the back rest or the seat member. The airbag module has an airbag and a module cover for enclosing the airbag. The module cover has a rated break line for releasing the airbag upon activation of the airbag module. The upholstery cover has a slit with opposed longitudinal edges. The module cover is positioned such that the rated break line extends parallel to an adjacent to slit such that the airbag is able to pass through the upholstery cover after activation of the airbag module. The opposed longitudinal edges are fastened to the module cover on opposite sides of the rated break line.
