Automotive body components and assemblies
The specification discloses automotive body components including roll-formed components and slip-plane brackets. The roll-formed components may be used in place of components manufactured using other techniques, such as hydroforming. The slip-plane brackets may be adjustably positioned on the roll-formed components. More specifically, the slip-plane brackets are adjustable in two or more dimensions (e.g. laterally and longitudinally) before attachment, so that the brackets may compensate for tolerances in the roll-formed components. Attachment techniques may include welding and/or adhering.
1. An automotive body assembly comprising:
a roll-formed component swept in at least one dimension along its length; and
at least one bracket having a pair of members engaging opposing walls of the component and, before being attached to the component, adapted to be adjustably positioned with respect to at least one of a first direction substantially parallel with the length of the component and a second direction substantially parallel with the opposing walls of the component, whereby the bracket provides dimensional compensation for precisely positioning an attachment portion of the bracket relative to the component, the attachment portion adapted to secure an additional body component.
2. An automotive body assembly as defined in claim 1 wherein the component is a pillar.
3. An automotive body assembly as defined in claim 1 wherein the component is a rail.
4. An automotive body assembly as defined in claim 1 wherein the component is swept in at least two orthogonal directions.
5. An automotive body assembly as defined in claim 1 wherein the at least one bracket includes a U-shaped cross section defined by the pair of members and an intermediate portion of the bracket extending between the pair of members.
6. An automotive body assembly as defined in claim 5 wherein the at least one bracket is adjustable at least laterally in the first direction and longitudinally in the second direction with respect to the component before attachment to the component, thereby compensating for tolerance variations in the swept curvature of the component when attaching the additional body component.
7. An automotive body assembly as defined in claim 1 wherein the at least one bracket is welded to the component.
8. An automotive body assembly as defined in claim 1 wherein structural adhesive adheres the at least one bracket to the component.
9. An automotive body assembly kit comprising:
an elongated component having a longitudinal curvature; and
a bracket engaging opposing sides of the elongated component and, before being fixedly attached to the elongated component, adjustably positionable with respect to the elongated component in at least two orthogonal directions for precisely positioning the bracket relative to the elongated component.
10. An automotive body assembly kit as defined in claim 9 wherein the elongated component is roll-formed.
11. An automotive body assembly kit as defined in claim 9 wherein the component is a pillar.
12. An automotive body assembly kit as defined in claim 9 wherein the component is a rail.
13. An automotive body assembly kit as defined in claim 9 wherein the component is curved in at least two orthogonal directions.
14. An automotive body assembly kit as defined in claim 9 wherein the bracket is adjustable at least laterally and longitudinally with respect to the component.
15. An automotive body assembly kit as defined in claim 9 wherein the bracket is adapted to be welded to the component.
16. An automotive body assembly kit as defined in claim 9 further comprising structural adhesive adapted to adhere the bracket to the component.
17. A method of manufacturing an automotive body assembly comprising:
roll-forming a component;
sweeping the component in at least two orthogonal directions along the component;
engaging opposing walls of the component with a bracket;
adjustably positioning the bracket with respect to the component to a desired position by moving the bracket relative to the component in at least one direction; and
attaching the bracket to the component in the desired position to compensate for tolerance variations in the swept curvature of the component.
18. A method as defined in claim 17 wherein the component is a pillar.
19. A method as defined in claim 17 wherein the component is a rail.
20. A method as defined in claim 17 wherein the bracket is positioned by moving the bracket in at least one of a first direction substantially parallel with a length of the component and a second direction substantially parallel with the opposing walls of the component.
21. A method as defined in claim 17 wherein the positioning step includes adjustably positioning the bracket in at least two orthogonal directions with respect to the component.
22. A method as defined in claim 21 wherein the at least two orthogonal directions include laterally and longitudinally with respect to the component.
23. A method as defined in claim 17 wherein the attaching step includes welding.
24. A method as defined in claim 17 wherein the attaching step includes structurally adhering.
25. An automotive body assembly comprising:
a roll-formed component swept in two orthogonal dimensions; and
a dimensional compensation bracket attached at opposing walls of the roll-formed component in an adjusted position having a portion of the bracket spaced laterally from the roll-formed component in a desired location to secure an additional vehicle component at a mounting plane of the bracket.
26. An automotive body assembly as defined in claim 25 wherein the component is at least one of a pillar and a rail.
27. An automotive body assembly as defined in claim 25 wherein an adhesive extends in the spacing between the roll-formed component and the dimensional compensation bracket to intersecure the two.
