Abstract

A roof ditch molding, roof ditch molding assembly, method of constructing a roof ditch molding, and method of assembling a roof ditch molding into a roof ditch of a vehicle are provided. The roof ditch molding includes an elongate metal substrate having an outer surface and an inner surface with opposite edge regions extending along a direction of a longitudinal axis between opposite ends. The inner surface faces and delimits an elongate channel extending between the opposite ends. The opposite edge regions are spaced from one another for snapping receipt of a plurality of fasteners therebetween, thereby eliminating the need for supplemental fastening features to fixedly secure the roof ditch molding within the roof ditch.

First claim

What is claimed is:

1. A method of constructing a roof ditch molding, comprising:
forming an elongate metal substrate in an extrusion process to include an outer surface and an inner surface with opposite edge regions extending along a direction of a first longitudinal axis between opposite ends;
forming the inner surface to face and delimit an elongate channel extending between the opposite ends; and
spacing the opposite edge regions from one another for resilient snapping receipt of an end of a fastener therebetween into the elongate channel.

2. A method of constructing a roof ditch molding, comprising:
forming an elongated metal substrate having an outer surface and an inner surface with opposite edge regions extending along a direction of a first longitudinal axis between opposite ends, the elongate metal substrate being formed in a roll forming process;
forming the inner surface to face and delimit an elongated channel extending between the opposite ends; and
spacing the opposite edge regions from one another for resilient snapping receipt of an end of a fastener therebetween into the elongated channel.

3. The method of claim 1 , further including bonding a polymeric material to the outer surface of the elongate metal substrate.

4. The method of claim 3 , further including extruding a pair of seal lips extending between the opposite ends and outwardly from the outer surface of the wall from the polymeric material.

5. A method of constructing a roof ditch molding, comprising:
forming an elongated metal substrate having an outer surface and an inner surface with opposite edge regions extending along a direction of a first longitudinal axis between opposite ends;
forming the inner surface to face and delimit an elongated channel extending between the opposite ends; and
spacing the opposite edge regions from one another for resilient snapping receipt of an end of a fastener therebetween into the elongated channel,
wherein the elongate metal substrate has an intermediate region and opposite sidewalls extending away from the intermediate region in laterally spaced relation from one another to opposite edge regions.

6. The method of claim 5 further including fixing a plurality of the fasteners within a roof ditch of a vehicle, with the fasteners extending to free end regions.

7. The method of claim 6 further including pressing the elongate metal substrate into the roof ditch and snapping at least a portion of the free end regions of the plurality of fasteners between the opposite edge regions and into the elongate channel.

8. The method of claim 7 further including deflecting the opposite edge regions resiliently outwardly away from one another with the free end regions of the fasteners and extending the free end regions of the fasteners beyond the opposite edge regions to allow the opposite edge regions to spring resiliently inwardly toward one another to capture the end regions of the fasteners in the elongate channel and retain the elongate metal substrate in fixed relation within the roof ditch.

9. The method of claim 7 further including fixing the elongate metal substrate to the fasteners without supplemental fastening features.

10. The method of claim 2 , further including bonding a polymeric material to the outer surface of the elongated metal substrate.

11. The method of claim 10 , further including bonding the polymeric material to the outer surface of the elongated metal process during the extrusion process.

12. The method of claim 10 , further including forming a pair of seal lips extending between the opposite ends and outwardly from the outer surface of the wall from the polymeric material.

13. A method of constructing a roof ditch molding, comprising:
forming an elongated metal substrate having an outer surface and an inner surface with opposite edge regions extending along a direction of a longitudinal axis between opposite ends;
forming the inner surface to face and delimit an elongated channel extending between the opposite ends;
spacing the opposite edge regions from one another for resilient snapping receipt of an end of a fastener therebetween into the elongated channel;
bonding a polymeric material to the outer surface of the elongated metal substrate; and
forming pair of seal lips extending between the opposite ends and outwardly from the outer surface of the wall from the polymeric material.
