Abstract

In accordance with a first aspect of the present disclosure, a motor vehicle airbag occupant restraint system fastener includes a metal clip, a first thermoplastic connector, a second thermoplastic connector, and a thermoplastic tether. The thermoplastic tether extends between the first and second thermoplastic connectors. Opposing ends of the thermoplastic tether are seamlessly integrated into the first and second thermoplastic connectors, respectively. The first and second thermoplastic connectors are formed of a first material and the thermoplastic tether is formed of a second material that is different from the first.

First claim

What is claimed is:

1. A method of manufacturing a tethered fastener assembly, the method comprising:
selecting a length of a flexible tether independent of any mold cavity of a mold;
inserting a first end of the flexible tether into a first mold cavity of the mold;
inserting a second end opposite the first end of the flexible tether into a second mold cavity of the mold;
molding a trim panel connector in the first mold cavity around the first end of the flexible tether, such that the flexible tether is integrally coupled to the first trim panel connector; and
molding a body connector in the second mold cavity around the second end of the flexible tether, such that the flexible tether is integrally coupled to the first body connector.

2. The method of claim 1 , further comprising:
selecting a first length of a first flexible tether, inserting a first end of the first flexible tether into the first mold cavity, inserting a second end of the first flexible tether into the second mold cavity, molding the trim panel connector around the first end of the first flexible tether, molding the body connector around the second end of the first flexible tether; and
selecting a second length of a second flexible tether that is different than the first length, inserting a first end of the second flexible tether into the first mold cavity, inserting a second end of the second flexible tether into the second mold cavity, molding the trim panel connector around the first end of the second flexible tether, molding the body connector around the second end of the second flexible tether.

3. The method of claim 1 , wherein molding the trim panel connector and the body connector further comprises molding the trim panel connector and the body connector from a first selected thermoplastic material, and wherein inserting the first and second ends of the flexible tether further comprises inserting the first and second ends of the flexible tether comprising a second thermoplastic material.

4. The method of claim 1 , wherein molding the trim panel connector and the body connector further comprises molding the trim panel connector and the body connector from a first selected thermoplastic material, and wherein inserting the first and second ends of the flexible tether further comprises inserting the first and second ends of the flexible tether comprising a second woven thermoplastic material.

5. The method of claim 1 , wherein inserting the first and second ends of the flexible tether comprises inserting a flat flexible tether, and further comprising folding the flexible tether into an accordion shape.

6. The method of claim 5 , further comprising stitching a first portion of the flat flexible tether to a second portion of the flat flexible tether.

7. The method of claim 1 , wherein molding the body connector includes molding a releasable fastener and wherein molding the trim panel connector including molding a cooperating releasable fastener, and further comprising coupling the releasable fastener to the cooperating releasable fastener.

8. The method of claim 1 , further comprising coupling the body connector to a metal clip.

9. The method of claim 1 , wherein molding the trim panel connector comprises molding a first flange having a convex outer surface; and
wrapping the flexible tether around the first flange, such that the flexible tether is adjacent to the outer surface.
