Abstract

Pillar apparatus for use with vehicles are disclosed. A disclosed vehicle includes a roof and a roof side rail including an inner panel that extends along a side of the roof. The vehicle also includes a pillar having an outer panel that extends along the side of the roof and is coupled between the roof and the inner panel. The pillar includes a structural feature positioned on the outer panel. The structural feature is configured to cause the outer panel to form a bend that distributes a first load onto an area of the inner panel to prevent the inner panel from tearing during a first vehicle impact event in which the first load is imparted on the outer panel.

First claim

What is claimed is:

1. A vehicle, comprising:
a roof;
a roof side rail including an inner panel that extends along a side of the roof; and
a pillar including an outer panel that extends along the side of the roof and is coupled between the roof and the inner panel, the pillar including a structural feature positioned on the outer panel, the structural feature configured to cause the outer panel to form a bend that distributes a first load onto an area of the inner panel to prevent the inner panel from tearing during a first vehicle impact event in which the first load is imparted on the outer panel,
wherein the roof side rail includes a reinforcing panel coupled to the outer panel and positioned between the outer panel and the inner panel, and
wherein the structural feature formed on the outer panel extends into a gap formed between the outer panel and the reinforcing panel.

2. The vehicle of claim 1 , wherein the pillar is an A-Pillar.

3. The vehicle of claim 1 , wherein the pillar includes multiple structural features positioned on the outer panel, two or more of the multiple structural features configured to cause the outer panel to form the bend when the first load is applied to an area of the outer panel proximate to the two more of the multiple structural features.

4. The vehicle of claim 3 , wherein:
the pillar includes a neutral axis at least partially defined by the outer panel, and
all of the multiple structural features are positioned above the neutral axis to prevent buckling of the pillar when a second load, different relative to the first load, is imparted on an end of the pillar during a second vehicle impact event different from the first vehicle impact event.

5. The vehicle of claim 3 , wherein each of the structural features is positioned on a top ridgeline of the outer panel.

6. The vehicle of claim 3 , wherein the multiple structural features are distributed across a partial length of the outer panel and evenly spaced from each other.

7. The vehicle of claim 3 , wherein each of the multiple structural features is interposed between the roof and a cover of a vehicle body.

8. The vehicle of claim 3 , wherein each of the multiple structural features is positioned in a segment of the pillar overlapping with the roof.

9. The vehicle of claim 1 , wherein a radius of the bend is based on one or more parameters of the structural feature.

10. The vehicle of claim 1 , wherein the structural feature includes a bead formed by one or more surfaces of the outer panel.

11. The vehicle of claim 1 , wherein the structural feature is positioned on a first portion of the outer panel and a second portion of the outer panel angled relative to the first portion.

12. The vehicle of claim 1 , wherein the structural feature includes a recessed area extending at least partially into the outer panel and a protruding area positioned on the outer panel opposite relative to the recessed area.

13. The vehicle of claim 1 , wherein the structural feature is oblong and extends away from the vehicle roof from a first end of the structural feature proximate to the vehicle roof to a second end of the structural feature opposite the first end.

14. The vehicle of claim 1 , wherein the reinforcing panel includes weld locations distributed on a portion of the reinforcing panel and recessed areas interposed between the weld locations, the structural feature extending at least partially into one of the recessed areas.

15. A pillar for a vehicle, comprising:
a first segment partially forming a roof side rail of the vehicle that is configured to provide support to a vehicle roof, the first segment configured to bend when a first load is applied to the first segment during a first vehicle impact event;
a second segment connected to the first segment and extending away from the first segment along a window of the vehicle; and
a structural feature positioned in the first segment, the structural feature configured to collapse while the first segment is bending to increase a bend radius associated with the first segment,
wherein the roof side rail includes a reinforcing panel coupled to the first segment and positioned between the first segment and the second segment, and
wherein the structural feature formed on the first segment extends into a gap formed between the first segment and the reinforcing panel.

16. The pillar of claim 15 , further including multiple structural features positioned in the first segment, two or more of the structural features configured to collapse to increase the bend radius of the first segment while the first segment is bending.

17. The pillar of claim 16 , wherein the pillar includes a panel having a top ridgeline and a bottom ridgeline adjacent the top ridgeline, the multiple structural features distributed on the top ridgeline.

18. The pillar of claim 15 , wherein all of the multiple structural features are positioned above a neutral axis of the pillar to prevent buckling of a panel of the pillar when a second load, different relative to the first load, is imparted on an end of the pillar during a second vehicle impact event different from the first vehicle impact event.
