Abstract

A method of manufacturing a handle intended to be gripped by an occupant of a vehicle is shown to comprise the steps of selecting a substrate including a first part and a second part. The first part and second part are wrapped with a covering material that may be a premium material such as leather and may also include a layer of foam padding. The first part and second part are assembled together and attached to each other. After the two parts are wrapped, the first part and second part are assembled together and attached to each other. A line of stitches may be formed on the covering material before the wrapping step that are wrapped to be visible on the handle.

First claim

What is claimed is:

1. A method of manufacturing a handle comprising:
selecting a substrate that includes a first and a second part;
wrapping the first and second part with a covering material;
assembling the first and the second part together after the above wrapping step;
attaching the first part to the second part; and
assembling rings over a first end and a second end of the handle over the covering material and the first and the second part.

2. The method of claim 1 further comprising:
applying a line of stitches on the covering material before the wrapping step that is visible on the handle.

3. The method of claim 1 further comprising:
applying two parallel lines of stitches on the covering material before wrapping the first and the second part with the covering material, wherein the two parallel lines of stitching are disposed at spaced locations on the covering material before wrapping and are adjacent to each other after wrapping around the substrate.

4. The method of claim 1 wherein the attaching step further comprises:
providing a plurality of heat stake posts on at least one of the first part and the second part; and
heat staking the first part and the second part together.

5. The method of claim 1 wherein the step of attaching the first part to the second part is selected from the group of steps consisting of:
applying an adhesive between the parts;
heat staking the parts together;
snapping the parts together with mating attachment features;
ultrasonically welding the parts together; and
friction welding the parts together.

6. The method of claim 1 further comprising:
assembling an arm to each end of the handle after attaching the first part to the second part.

7. A handle comprising:
a substrate including a plurality of assembled parts;
a covering including an intermediate portion wrapped around the substrate and a peripheral portion secured between the parts; and
a first ring encircling a first end of the handle and a second ring encircling a second end of the handle, the first ring and the second ring holding the covering against the first and the second part at the first the second ends.

8. The vehicle handle of claim 7 further comprising:
a line of stitches provided on the intermediate portion of the covering material that is outside the parting line and adjacent the peripheral portion to be visible on the handle.

9. The vehicle handle of claim 7 further comprising:
two parallel lines of stitches provided on the intermediate portion of the covering material that are outside the parting line and adjacent the peripheral portions, wherein the two parallel lines of stitching are adjacent to each other after wrapping around the substrate to be visible on the handle.

10. The vehicle handle of claim 7 further comprising:
providing a plurality of heat stake posts on at the assembled part that connect the assembled parts together.

11. The vehicle handle of claim 7 wherein the assembled parts are secured together by an attachment mechanism selected from the group of attachment mechanisms consisting of:
an adhesive;
a plurality of heat stakes;
a set of mating attachment snaps;
an ultrasonic weld; and
a friction weld.

12. The vehicle handle of claim 7 further comprising:
an arm assembled to each end of the handle that connect the handle to a headliner of a vehicle.
