Abstract

A listing bead for use in securing upholstery trim covers to upholstery clips embedded in a foam substrate that includes finger-friendly formations on its surface. The formation in an illustrative embodiment defines a flat top at the upper end of a neck that extends between the bead and the top. Illustratively, the top is formed in two outwardly bent L-shapes extending at right angles in opposing directions from the neck. The bead, neck and flat top define confronting halves, joined at the bottom edge, which encase a web that is constructed and arranged to be secured to the trim cover by adhesives, welding or stitching. The web illustratively includes punched and/or cut holes (tactile indicia) at predetermined intervals therealong that provide visual and tactile feedback to the installer on the approximate location of clips in the substrate during assembly.

Claims

1. A listing for assembling trim covers to a foam substrate containing one or more clips comprising:

a strip of web material configured to be attached to a trim cover, wherein the web includes one or more tactile indicia indicating positions of the clips in the foam substrate; and

a listing bead assembly defining a cross section with tapered shape with a bottom tip and upper barbs, a neck extending above the barbs with the web affixed to the neck, and a top that extends outwardly from the neck on at least one side of the bead assembly and provides a surface for contact of an installer'"'"'s finger therewith when providing a push-in force to engage the bead assembly with the one of the clips.

2. The listing as set forth in claim 1 wherein the bead assembly defines a pair of opposing halves that sandwich a web for attachment to the trim cover.

3. The listing as set forth in claim 2 wherein the top extends outwardly in opposing directions from the neck on each of the opposing halves.

4. The listing as set forth in claim 3 wherein the top defines an overall outward extension width of between approximately 4 and 10 millimeters.

5. The listing as set forth in claim 4 wherein the top defines a substantially flat upper surface and the top and neck collectively define a T-shape.

6. The listing as set forth in claim 5 wherein the top defines a thickness perpendicular to the width of approximately 0.5-2.5 millimeters.

7. The listing as set forth in claim 6 wherein the thickness is approximately 1 millimeter.

8. The listing as set forth in claim 1 wherein the tactile indicia define cutouts.

9. The listing as set forth in claim 1 wherein the bead assembly and the web are each composed of thermoplastic, and are bonded together.

10. The listing as set forth in claim 1 wherein the tapered shape defines a pair of opposing surfaces oriented at an angle of approximately 25 degrees with respect to each other.

11. The listing as set forth in claim 1 wherein the neck defines a thickness constructed and arranged to generate flexure in opposing legs of the engaged one of clips.

12. A vehicle seat constructed with the clips of the foam substrate in engagement with the listing of claim 1.

20. The listing as set forth in claim 1 wherein the barbs have top surfaces that are set off from each other at an angle of approximately 122 degrees.

13. A method for assembling a trim cover to a vehicle seat to a foam substrate containing clips, comprising the steps of:

positioning a listing bead assembly defining a cross section with tapered shape with a bottom tip and upper barbs, a neck affixed to a web and extending above the barbs, and a top that extends outwardly from the neck on at least one side of the bead assembly;

aligning the listing bead with the clips based upon indicia provided in the web; and

engaging the top with a finger and applying a push-in force to engage the bead assembly with the one of the clips so that the upper barbs of the bead assembly become captured by barbs of each of the clips.

14. The method as set forth in claim 13 further comprising locating the clips in a trench of the foam substrate.

15. The method as set forth in claim 13 wherein the indicia comprise holes formed through the web adjacent to the bead.

16. A method for manufacturing a listing for assembling trim covers to a foam substrate containing one or more clips, the method comprising:

extruding in an extrusion die a listing bead assembly defining a cross section with tapered shape with a bottom tip and upper barbs, a neck extending above the barbs and a top that extends outwardly from the neck on at least one side of the bead assembly;

affixing a web to the neck; and

forming one or more tactile indicia on the web indicating positions of the clips in the foam substrate.

17. The method as set forth in claim 16, wherein forming one or more tactile indicia comprises forming one or more holes in the web.

18. The method as set forth in claim 16, wherein extruding the listing beads includes extruding the upper barbs with top surfaces that are set off from each other at an angle of approximately 122 degrees.

19. The method as set forth in claim 16, further comprising sandwiching the web within the channel as it exits an extrusion die in a semi-hardened state.
