Abstract
A methodology for adhesively attaching a barrier sheet to a motor vehicle inside door panel. A plurality of adhesive beds are disposed on the attachment face of a barrier sheet, whereby pressure applied to the barrier sheet causes the adhesive beads to wet-out with respect to the door inside panel and mergingly wet-out with respect to each other so as to thereby form an adhesive band. Visual inspection of the continuity of the merged wet-out through the barrier sheet provides installer feedback regarding installation integrity.
Claims15
A motor vehicle door comprising:
- an inside door panel having at least one opening formed therein;
- a barrier sheet having a perimeter configured to coveringly overlap at least one opening formed in the inside door panel;
- at least one adhesive bead set adhesively attaching said barrier sheet to said inside door panel, wherein each adhesive bead set comprises:
- a plurality of adhesive beads, each adhesive bead being disposed in parallel relationship to each and in locally parallel relation to the perimeter;
- wherein the adhesive beads are preselected and mutually spaced so that adjacent adhesive beads are mutually initially separated then wet-out with respect to each other and to said inside door panel when pressure is applied to said barrier sheet toward said inside door panel;
- a door panel trough formed in said inside door panel, said door panel trough having a predetermined path including at least one gravitationally low point;
- and
- at least one drain hole formed in said inside door panel intersecting said door panel trough, a drain hole of said at least one drain hole being disposed at each said gravitationally low point, respectively;
- wherein said at least one adhesive bead set comprises:
- an inside adhesive bead set located adjacent one side of said door panel trough;
- and
- an outside adhesive bead set located adjacent the other side of said door panel trough, wherein said outside bead set is located closer to said periphery than is said inside adhesive bead set;
- wherein said inside adhesive bead set intersects said at least one drain hole.
A method for providing a barrier sheet for selectively covering an inside door panel of a motor vehicle door, comprising the steps of:
- providing a barrier sheet having a predetermined perimeter for selectively covering a predetermined inside door panel of a motor vehicle door;
- applying a plurality of adhesive beads to an application face of the barrier sheet, said plurality of adhesive beads comprising at least one adhesive bead set, wherein each adhesive bead set comprises a plurality of mutually parallel and mutually spaced apart adhesive beads, the beads being disposed in substantially parallel relation to the perimeter;
- placing the application face of the barrier sheet against the inside door panel;
- pressing upon the barrier sheet toward the inside door panel to thereby cause the adhesive beads to wet-out with respect to the inside door panel;
- visually inspecting through the barrier sheet continuity of the merged wet-out of the adhesive band formed of each adhesive bead set in response to said step of pressing;
- identifying, in response to said step of inspecting, whether any area of the adhesive beads of each said adhesive bead set lacks merged wet-out continuity;
- and
- re-pressing upon the barrier sheet toward the door inside panel any area identified in said step of identifying;
- wherein in said step of applying, the adhesive beads of each adhesive bead set has a predetermined spacing between adjacent adhesive beads thereof such that during said step of pressing, the adjacent adhesive beads mergingly wet-out with respect to each other to thereby collectively form an adhesive band.
