B-pillar deformation mode
A vehicle comprises: a vehicle structure without a continuous roof rail; a B-pillar attached to the vehicle structure, the B-pillar having a first initiator; and a header attached to the B-pillar and extending at least partly across the vehicle, the header having a second initiator, wherein the first and second initiators are configured to provide a B-pillar deformation mode upon side impact.
1. A vehicle comprising:
a vehicle structure without a continuous roof rail;
a B-pillar attached to the vehicle structure, the B-pillar having a first initiator; and
a header attached to the B-pillar and extending at least partly across the vehicle, the header having a second initiator, wherein the first and second initiators are configured to provide a B-pillar deformation mode upon side impact.
2. The vehicle of claim 1 , wherein the vehicle structure further comprises a side sill, and wherein the B-pillar extends from the side sill.
3. The vehicle of claim 1 , wherein the vehicle structure further comprises a roof spine, and wherein the header is connected to the roof spine.
4. The vehicle of claim 1 , wherein the B-pillar and the header are attached at an angle oriented outward relative to the vehicle, and wherein the first and second initiators are configured so as to tend to preserve the angle upon the side impact.
5. The vehicle of claim 4 , wherein the angle is approximately 90 degrees.
6. The vehicle of claim 1 , wherein the first and second initiators are configured so the B-pillar deformation mode preserves an interior gap for an airbag.
7. The vehicle of claim 1 , wherein the vehicle structure further comprises at least one dual hinge door, and wherein the B-pillar and the header are positioned adjacent an opening for the dual hinge door.
8. The vehicle of claim 1 , wherein the B-pillar is positioned on one side of the vehicle, the vehicle further comprising another B-pillar on an opposite side of the vehicle, the other B-pillar having a third initiator.
9. The vehicle of claim 1 , wherein the B-pillar is configured to direct load along the header upon the side impact.
10. The vehicle of claim 1 , wherein at least one of the first and second initiators comprises a weakening in a material of the B-pillar or the header.
11. The vehicle of claim 1 , wherein at least one of the first and second initiators comprises an indentation in a material of the B-pillar or the header.
12. The vehicle of claim 1 , wherein the B-pillar has at least two first initiators, the first initiators positioned on respective ridges of, or respective corners of a cross-section profile of, the B-pillar.
13. The vehicle of claim 1 , wherein the second initiator comprises a narrowed portion of a profile of the header.
14. The vehicle of claim 13 , wherein the header has a side-to-side span on the vehicle, and wherein the narrowed portion is centered in the side-to-side span.
15. The vehicle of claim 1 , further comprising a reinforcement between at least the B-pillar and the header.
16. The vehicle of claim 15 , wherein the reinforcement comprises a reinforcement skeleton for a tube of an A-pillar, a tube of the B-pillar, and the header.
17. The vehicle of claim 1 , wherein the reinforcement comprises a formable material applied to a tube of an A-pillar, a tube of the B-pillar, and the header, which formable material subsequently hardens to form the reinforcement.
18. A vehicle comprising:
a vehicle structure without a continuous roof rail;
a B-pillar attached to the vehicle structure;
a header attached to the B-pillar and extending at least partly across the vehicle;
means for providing a B-pillar deformation mode for the B-pillar and the header upon side impact.
