Abstract

Claims (18)

1. A support rail for a vehicle comprising:

a tubular body formed by a wall;

first and second flanges formed from a pinched portion of the wall of the body that extend outwardly from the body along at least a first part of the length of the tubular body, the first flange spans only a portion of the tubular body and terminates at an intermediate point along the length of the tubular body, the second flange continues along at least a second part of the tubular body, wherein the pinched portion of the wall is formed to have two wall thicknesses; and

wherein one of the flange has a localized area where at least one wall thickness is removed to facilitate welding the support rail to another portion of the vehicle.

2. The support rail of claim 1 wherein the tubular body has a hollow cross-section, and wherein the hollow cross-section of the tubular body at the first part of the length of the tube is less than the hollow cross-section of the tubular body at the second part of the length of the tube.

3. The support rail of claim 1 further comprising an integral end connector provided at the end of the tubular member, wherein the end connector defines a notch formed in the wall that provides access to a diametrically opposed portion of the end connector to facilitate welding the end of the rail to another portion of the vehicle.

4. The support rail of claim 1 wherein the support rail is a combination of an A-pillar and a roof rail, and wherein the two flanges extend from the front of the A-pillar at a forward end of the A-pillar to a door opening.

5. The support rail of claim 4 one of the two flanges extends beyond the other flange from the a point above the door opening toward the rear of the vehicle.

6. The support rail of claim 5 wherein the tubular body has a hollow cross-section, and wherein the hollow cross-section of the tubular body where the two flanges are formed on the tube is less than the hollow cross-section of the tubular body where the one flange extends beyond the other flange.

7. The support rail of claim 4 one of the two flanges is a windshield support flange and the other flange is a door opening flange.

8. A roof rail for a vehicle that has a windshield and a roof, the roof rail extending from a side of the windshield and along a side of the roof, wherein the roof rail comprises:

an A-pillar disposed adjacent the windshield having a front door opening flange and a windshield support flange, wherein the front door opening flange and the windshield support flange extend outwardly from radially spaced portions of a tubular section;

an intermediate portion of the roof rail formed as a rearward continuation of the A-pillar and disposed adjacent a front portion of the roof continuing the front door opening flange from the front portion and having a roof support flange, wherein the front door opening flange and the roof support flange extend outwardly from radially spaced portions of the tubular section;

a back portion of the roof rail disposed adjacent a rear portion of the roof having a rear door opening flange and an upper surface of the tubular section for supporting the roof, wherein the rear door opening flange extends outwardly from the tubular section.

9. The roof rail of claim 8 further comprising a tube connector integrally formed at the front end of the front portion of the roof rail, the tube connector having a notch in the tubular section that provides access to a single wall thickness of the tube connector portion that facilitates welding to the single wall thickness of the tubular section.

10. The roof rail of claim 8 further comprising a tube connector portion integrally formed at the back end of the back portion of the roof rail, the tube connector portion having a notch in the tubular section that provides access to a single wall thickness of the tube connector portion that facilitates welding to the single wall thickness of the tubular section.

11. The roof rail of claim 8 further comprising a tube connector portion integrally formed at the back end of the back portion of the roof rail, the tube connector portion having an opening in the tubular section to reduce the number of metal thicknesses that are welded together.

12. The support rail of claim 8 wherein the tubular section has a hollow cross-section, and wherein the hollow cross-section of the tubular body at the first part of the length of the tube is less than the hollow cross-section of the tubular body at the second part of the length of the tube.
