Abstract

An absorbing bracket can be coupled to a vehicle body and can absorb energy from an external force applied to the vehicle body. In an embodiment, the energy absorbing bracket includes a bracket body at least partly made of a rigid material. The bracket body includes a deformable wall defining a first edge and a second edge opposite the first edge. The first edge is parallel to the second edge. The bracket body defines a plurality of slots extending through the deformable wall. Each slot extends along a slot axis. Further, each slot axis is obliquely angled relative to the first edge.

First claim

The invention claimed is:

1. An energy absorbing bracket, comprising:
a bracket body including a deformable wall, wherein the deformable wall defines a first edge and a second edge opposite the first edge, the first edge is parallel to the second edge, the bracket body defines a plurality of slots extending through the deformable wall, and each of the slots extends along a slot axis, and each of the slot axes is obliquely angled relative to the first edge, and the plurality of slots are disposed between the first edge and the second edge.

2. The energy absorbing bracket of claim 1 , wherein the slots are equal in size.

3. The energy absorbing bracket of claim 1 , wherein the slots are parallel to one another.

4. The energy absorbing bracket of claim 1 , wherein the deformable wall further defines a third edge that interconnects the first edge and the second edge, and a fourth edge opposite the third edge that interconnects the first edge and the second edge, the bracket body defines a linear axis extending between the third edge and the fourth edge, the linear axis is parallel to the first edge, wherein each of the slots are arranged along the linear axis between the third edge and the fourth edge such that the linear axis intersects a center point of each of the slots.

5. The energy absorbing bracket of claim 1 , wherein the bracket body is at least partially made of a rigid material.

6. The energy absorbing bracket of claim 5 , wherein each of the slots has a first slot end and a second slot end opposite to the first slot end defining a slot length extending from the first slot end to the second slot end, the slot length is substantially parallel to the slot axis and is about twenty millimeters.

7. The energy absorbing bracket of claim 1 , wherein the deformable wall further defines a third edge, and a fourth edge opposite the third edge, the third edge interconnects the first edge and the second edge, the fourth edge interconnects the first edge and the second edge, and the plurality of slots are arranged in a stepped configuration between the third edge and the fourth edge.

8. The energy absorbing bracket of claim 7 , wherein the bracket body defines a first linear axis and a second linear axis extending between the third edge and the fourth edge, wherein each of the slots are arranged along the first linear axis and the second linear axis between the first edge and the second edge such that the second linear axis intersects a center point of each of the slots and the second linear axis is obliquely angled relative to the first linear axis.

9. The energy absorbing bracket of claim 8 , wherein the first linear axis intersects the center point of one of the slots.

10. The energy absorbing bracket of claim 9 , wherein each of the slots has a slot width, and the slot width is about ten millimeters.

11. A vehicle, comprising:
a vehicle body;
an energy absorbing bracket coupled to the vehicle body, wherein the energy absorbing bracket includes:
a bracket body including a deformable wall defining a first edge and a second edge opposite the first edge, wherein the bracket body defines a plurality of slots extending through the deformable wall, and each of the slots extends along a slot axis, and each of the slot axes is obliquely angled relative to the first edge;
wherein the deformable wall further defines a third edge and a fourth edge opposite the third edge, the third edge interconnects the first edge and the second edge, the fourth edge interconnects the first edge and the second edge, the plurality of slots are arranged in a stepped configuration between the third edge and the fourth edge; and

wherein the bracket body defines a first linear axis extending between the first edge and the second edge, the first linear axis is parallel to the third edge, the slots are arranged along a second linear axis between the first edge and the second edge, the second linear axis intersects a slot center of each of the slots, and the second linear axis is obliquely angled relative to the first linear axis.

12. The vehicle of claim 11 , wherein the slots are equal in size.

13. The vehicle of claim 11 , wherein the slots are parallel to one another.

14. The vehicle of claim 11 , wherein the bracket body is at least partially made of a rigid material.

15. The vehicle of claim 14 , wherein each of the slots has a first slot end and a second slot end opposite to the first slot end defining a slot length extending from the first slot end to the second slot end, the slot length is substantially parallel to the slot axis and is about twenty millimeters.

16. The vehicle of claim 11 , wherein the first linear axis intersects the slot center of one of the slots.

17. The vehicle of claim 16 , wherein each of the slots has a slot width, and the slot width is about ten millimeters.
