1. A method of computer-assisted assessment of vehicle seat bottom design, the method comprising:
- in response to user identification of a vehicle seat bottom, automatically importing a data file representing an internal structure component infrastructure for the vehicle seat bottom from a computer memory for use with a computer assisted drawing (CAD) application operating on a computer to generate a visual output, the internal structure component infrastructure visually representing internal structural components of the seat bottom;
in response to user identification of a body profile, automatically importing a pan shape data object representing the body profile from the computer memory for input to the CAD application, the pan shape data object visually representing a pressure distribution of a seat occupant matching the identified profile as at least a two-dimension object having an upper and a lower side;
overlaying the pan shape data object relative to the internal structure component infrastructure so that the visual output shows both of the pan shape object and the structural components; and
automatically identifying portions of the internal structural components within the visual output that penetrate through both of the upper and lower sides of the pan shape object as areas where the seat occupant experiences undesirable pressures.

Abstract
Method of computer-assisted assessment of seat design. The method being applicable to any type of seating, including but not limited to vehicle seating commonly employed in automobiles, watercraft, aircraft, etc. The method may include overlaying a shaped data object relative to an architectural drawing to facilitate assessing component comportment with desired structural boundaries.

9. A method of computer-assisted seat design using a computer assisted drawing (CAD) application, the method comprising:
-
in response to user selection a vehicle seat, the CAD application automatically generating a visual output representing an internal structural component drawing of at least a portion of the vehicle seat; in response to user selection of a body profile, the CAD application automatically importing a shaped data object representing pressure distribution of the body profile, the shaped object defining structurally limiting boundaries of the body profile as a two-dimensional shape; in response to user selection of a cross-section of the drawing to show an internal cross-section of internal structural components of the vehicle seat, the CAD application automatically overlaying the two-dimensional shape relative to the internal cross-section within the visual output and automatically generating electronic data representing portions of the internal cross-section where portions of the internal structural components extending beyond a boundary defined by the two-dimensional shape. - View Dependent Claims (10, 11, 12, 13, 14, 15)
