Assembly for attaching an emblem onto an airbag storage compartment cover
An assembly for attaching an emblem onto the front face of an airbag storage enclosure cover has a plurality of attachment posts that project from the back surface of the emblem and extend through the cover from the front face to terminate in free ends remote from the emblem. An attachment backing sheet is positioned against the rear face of the cover, whereby the attachment posts also extend through the attachment backing sheet with the free end of each positioned on the side of the attachment backing sheet opposite from the cover. A plurality of radially-enlarged attachment nuggets are formed or joined individually in a one-to-one association to the free end of the attachment posts, and each of the attachment nuggets is secured to the backing sheet in proximity to the associated attachment post. The attachment backing sheet thus tethers each of the attachment nuggets to the cover in the event of the mechanical failure of an associated attachment post. The attachment nuggets may be integrally formed with or bonded to the free ends of the attachment posts. If the attachment backing sheet is made of a porous material, such as a fabric, a mesh, or a screen, the material of the attachment nuggets permeates pores in the material of the attachment backing sheet in proximity to each associated attachment post. If the attachment backing sheet is made of a plastic material, the attachment nuggets are bonded with adhesive to the attachment backing sheet.

3. An assembly as recited in claim 1 , wherein the material of the attachment backing sheet is chosen from the group of materials comprising a fabric, a mesh, and a screen.
4. An assembly as recited in claim 2 , wherein each of the plurality of attachment nuggets is bonded to the attachment backing sheet in proximity to the attachment post associated therewith.
5. An assembly as recited in claim 1 , wherein each of the plurality of attachment nuggets is bonded to the free end of the attachment post associated therewith.
6. An assembly as recited in claim 5 , wherein each of the plurality of attachment nuggets is bonded to the attachment backing sheet in proximity to the attachment post associated therewith.
7. An assembly as recited in claim 5 , wherein:
(a) the attachment backing sheet is comprised of a porous material; and
(b) the material of each of the plurality of attachment nuggets permeates pores in the material of the attachment backing sheet in proximity to the attachment post associated therewith.
8. A system for attaching an emblem onto the front face of the cover for an airbag storage enclosure, the system comprising:
(a) an attachment backing sheet positioned against the rear face of the cover, the attachment backing sheet is comprised of a porous material; and
(b) a plurality of attachment posts projecting from the back surface of the emblem, each of the attachment posts being extendable through the cover from the front face thereof and through the attachment backing sheet to terminate in a respective free end thereof positioned on the side of the attachment backing sheet opposite from the cover, the free end of each of each of the plurality of attachment posts being deformable into a respective radially-enlarged attachment nugget, and each of the attachment nuggets becoming thereby secured to the attachment backing sheet in proximity to the attachment post associated therewith such that material of each of the plurality of attachment nuggets permeates pores in the porous material of the attachment backing sheet.
9. A method for attaching an emblem onto the front face of the cover for an airbag storage enclosure, the method comprising the steps of:
(a) disposing an attachment backing sheet against the rear face of the cover;
(b) causing a plurality of attachment posts to project from the back surface of the emblem, each of the attachment posts terminating in a free end remote from the emblem;
(c) advancing the free ends of the plurality of attachment posts through the cover from the front face thereof;
(d) piercing the free ends of the plurality of attachment posts through the attachment backing sheet;
(e) joining a plurality of radially-enlarged attachment nuggets individually in a one-to-one association to the free ends of each of the plurality of attachment posts; and
(f) securing each of the plurality of attachment nuggets to the attachment backing sheet in the vicinity of the respective attachment post associated therewith such that material of each of the plurality of attachment nuggets permeates pores in the attachment backing sheet.
10. A method as recited in claim 9 , wherein the step of advancing comprises the steps of:
(a) forming a plurality of apertures through the cover corresponding in number and pattern to the number and the pattern of the plurality of attachment posts on the back surface of the emblem;
(b) entering the free ends of the plurality of attachment posts from the front face of the cover individually in one-to-one association into the plurality of apertures through the cover; and
(d) bringing the back surface of the emblem into contact with the front face of the cover.
11. A method as recited in claim 9 , wherein the step of piercing comprises the steps of:
(a) forming a plurality of slits through the attachment backing sheet corresponding in number and pattern to the number and the pattern of the plurality of attachment posts on the back surface of the emblem;
(b) entering the free ends of the plurality of attachment posts from the side of the attachment backing sheet facing the cover individually in one-to-one association into of the plurality of the slits through the attachment backing sheet; and
(d) sandwiching the cover between the attachment backing sheet and the back surface of the emblem.
12. A method as recited in claim 9 , wherein the step of joining and the step of securing are performed simultaneously.
13. A method as recited in claim 9 , wherein the step of joining comprises the step of deforming the material of the free end of each of the plurality of attachment posts radially outwardly of each of the plurality of attachment posts.
14. A method as recited in claim 13 , wherein the step of deforming comprises the step of softening the material of the free end of each of the plurality of attachment posts using a treatment selected from the group of treatments comprising ultrasonic heating, conduction heating, and convection heating.
15. A method as recited in claim 9 , wherein the step of joining comprises the step of bonding the plurality of attachment nuggets individually in a one-to-one relationship to the free ends of the plurality of corresponding attachment posts.
