Abstract

A pillar trim component can include a main body portion and an airbag support portion extending from the main body portion. An attachment portion can include an outwardly extending portion connected to the airbag support portion, an angled portion connected to an outer end of the outwardly extending portion, and an inboard stabilizing web extending between the outwardly extending portion and the angled portion. An airbag positioning portion can be defined by at least a portion of an upwardly extending wall of the airbag support portion angled inboard toward the main body portion. An airbag guide portion can be defined by a deployment surface located above the main body portion and extending between the main body position and the airbag support portion. A headliner retaining portion can be defined by a recess formed between the deployment surface and the main body portion.

6. The pillar structure of claim 5 further comprising:

an attachment portion extending from the airbag support portion and connecting the pillar trim component to the pillar panel, the attachment portion located between two upwardly extending walls of the airbag positioning portion.

7. The pillar structure of claim 1 further comprising:

a roof portion; and

a pillar panel connected to the roof portion and an aperture extending through both the roof portion and the pillar panel.

8. The pillar structure of claim 7, wherein an inverted T-shaped periphery formed through both the roof portion and the pillar panel defines the aperture.

9. The pillar structure of claim 8 further comprising:

an attachment portion connecting the pillar trim component to the roof portion and pillar panel through the inverted T-shaped periphery defining the aperture.

10. The pillar structure of claim 1 further comprising:

a headliner retaining portion located between the main body portion and the airbag support portion.

11. The pillar structure of claim 10, wherein the airbag guide portion is defined by a deployment surface located above the main body portion, and wherein the deployment surface is angled relative to the airbag support portion, wherein a portion of the deployment surface defines a plane that passes above the headliner retainer portion.

12. A pillar trim component comprising:

a main body portion;

an airbag support portion extending from the main body portion, the airbag support portion having an airbag guide portion, and a reinforcement portion connecting the airbag guide portion to the main body portion; and

a bow-shaped airbag positioning portion having an airbag contact surface, a lower portion extending inboard from a proximate end of the airbag positioning portion to the airbag contact surface, and an upper portion extending outboard from the airbag contact surface to a distal end of the airbag positioning portion.

13. The pillar trim component of claim 12 further comprising:

an attachment portion extending from the airbag support portion.

14. The pillar trim component of claim 13, wherein the attachment portion is defined by an outwardly extending portion connected to the airbag support portion and an angled portion connected to an outer end of the outwardly extending portion.

15. The pillar trim component of claim 14, wherein the attachment portion is further defined by an inboard stabilizing web extending between the outwardly extending portion and the angled portion.

16. The pillar trim component of claim 12, wherein the airbag contact surface of the airbag positioning portion is further inboard than an outboard side of the airbag support portion and the distal end of the airbag positioning portion.

17. The pillar trim component of claim 16, wherein the airbag positioning portion is defined by at least a portion of an upwardly extending wall angled inboard relative to a line orthogonal to the airbag support portion.

18. The pillar structure of claim 17 further comprising:

an attachment portion extending from the airbag support portion, the attachment portion located between two upwardly extending walls of the airbag positioning portion.

19. The pillar trim component of claim 12 further comprising:

a headliner retaining portion located between the main body portion and the airbag support portion.

20. The pillar trim component of claim 19, wherein the airbag guide portion is defined by a deployment surface located above the main body portion and extending between the main body portion and the airbag support portion, the deployment surface angled relative to the airbag support portion, wherein a portion of the deployment surface defines a plane that slopes vertically downward as it extends inboard, the plane extending above the headliner retaining portion.

21. The pillar trim component of claim 19, wherein the headliner retaining portion is defined by a recess formed between the airbag support portion and the main body portion.

22. A pillar trim component comprising:

a main body portion; and

an airbag support portion extending from the main body portion;

a bow-shaped airbag positioning portion extending vertically upward from an outboard side of the airbag support portion and having a lower portion extending in a direction inboard toward the main body portion and an upper portion extending outboard away from the main body portion;

an attachment portion extending in a direction outboard away from the main body portion; and

an airbag guide portion extending from an inboard side of the airbag support portion and angled relative to the airbag support portion.

23. A method for positioning an airbag in a vehicle comprising:

slipping an outboard angled distal end of a bow-shaped airbag-positioning portion of a trim component between a vehicle body element and a previously installed airbag connected to the vehicle body element; and

repositioning the airbag slightly inboard from the vehicle body element by urging the airbag inboard with the bow-shaped airbag-positioning portion while connecting the trim component to the vehicle body element.

24. The method of claim 23, wherein the airbag is a side curtain airbag, the vehicle body element is a roof rail, and the trim component is a pillar trim component operable to move the side curtain airbag away from the roof rail during installation of the pillar trim component.

25. The method of claim 23 further comprising:

supporting the airbag on an airbag support portion of the trim component.

26. The method of claim 23 further comprising:

27. The method of claim 26, wherein inserting an attachment portion further comprises:

inserting an upwardly extending part of the attachment portion into an inverted T-shaped aperture formed in the vehicle body element; and

moving a lower portion of the trim component outboard and upward to engage an inverted T-shaped cross section of the attachment portion through the inverted T-shaped aperture formed in the vehicle body element as the airbag positioning portion of the trim component moves the airbag in an inboard direction away from the vehicle body element.

28. A pillar trim component comprising:

32. The pillar trim component of claim 31, wherein the attachment portion is defined by an outwardly extending portion connected to the airbag support portion, an angled portion connected to an outer end of the outwardly extending portion, and an inboard stabilizing web extending between the outwardly extending portion and the angled portion.

33. The pillar trim component of claim 28 wherein the headliner retaining portion is defined by a recess formed between the airbag guide portion and the main body portion.

34. The pillar trim component of claim 28 further comprising:
