Abstract

A vehicle assembly includes a vehicle body and a vehicle seat. The vehicle body includes a frame backing member elongated in a length direction of the vehicle seat. The vehicle seat includes a seat base and a seat back connected to the seat base. The seat back is connected to the frame backing member. A mounting bracket is connected to an upper portion of a seat back frame. An energy attenuating member positioned in a space between the seat back frame and the frame backing member interconnects the mounting bracket and the frame backing member. During a crash event the energy attenuating member is configured to collapse between the seat back and the frame backing member to absorb kinetic energy in the vehicle seat when the seat back is driven toward the frame backing member.

First claim

The invention claimed is:

1. A vehicle assembly comprising:
a vehicle body including a frame backing member; and
a vehicle seat including a seat base and a seat back connected to the seat base, the seat back connected to the frame backing member, the frame backing member elongated in a length direction of the vehicle seat,
wherein a mounting bracket is connected to an upper portion of a seat back frame, an energy attenuating member positioned in a space between the seat back frame and the frame backing member interconnects the mounting bracket and the frame backing member, wherein during a crash event the energy attenuating member is configured to collapse and fold relative to a height direction of the vehicle assembly between the seat back and the frame backing member to absorb kinetic energy in the vehicle seat when the seat back is driven toward the frame backing member.

2. The vehicle assembly of claim 1 , wherein the mounting bracket includes a first mounting part and a second mounting part extended from the first mounting part, the first mounting part adapted for connection to the seat back frame, the second mounting part adapted for connection to the energy attenuating member.

3. The vehicle assembly of claim 2 , wherein the first mounting part extends substantially perpendicular to the seat back frame, and the second mounting part extends substantially parallel to the seat back frame.

4. The vehicle assembly of claim 3 , including a seat back plate secured between the mounting bracket and the seat back frame, the first mounting part connected to the seat back plate.

5. The vehicle assembly of claim 4 , wherein the second mounting part is spaced from the seat back frame via a leg member of the mounting bracket.

6. The vehicle assembly of claim 4 , including a seat back connecting plate secured to the seat back frame, the seat back plate mounted to the connecting plate.

7. The vehicle assembly claim 2 , wherein the energy attenuating member includes a first wall section and a separate second wall section secured to the first wall section, wherein in a side view of the energy attenuating member the second wall section is bent around the first wall section to have a U-shaped profile.

8. The vehicle assembly of claim 7 , wherein the second wall section is secured beneath the first wall section relative to the height direction of the vehicle assembly.

9. The vehicle assembly of claim 7 , wherein a central portion of the first wall section is formed with a kink or bend directed in a fold direction of the first wall section when the energy attenuating member collapses between the seat back and the frame backing member.

10. The vehicle assembly of claim 9 , wherein the first wall section is formed with at least one first strengthening rib extended between a proximal end portion and a distal end portion of the energy attenuating member, the first strengthening rib bifurcated by the kink or bend, and
the second wall section is formed with at least one second strengthening rib extended continuously between the proximal end portion and the distal end portion.

11. The vehicle assembly of claim 1 , wherein the vehicle body includes an interior panel sized to cover the space between the seat back frame and the frame backing member, the interior panel including a removable tray cap proving access to the connection between the mounting bracket and the seat back frame.

12. A vehicle assembly comprising:
a vehicle body including a frame backing member;
a seat having a seat base and a seat back connected to the seat base, an upper portion of a seat back frame aligned with the frame backing member relative to a height direction of the vehicle assembly;
an energy attenuating member positioned in a space between the seat back frame and the frame backing member, wherein during a crash event the energy attenuating member is configured to collapse and fold relative to the height direction of the vehicle assembly between the seat back and the frame backing member to absorb kinetic energy in the vehicle seat when the seat back is driven toward the frame backing member; and
a mounting bracket positioned at the upper portion of the seat back frame, the mounting bracket includes a first mounting part and a second mounting part extended from the first mounting part, the first mounting part adapted connected to the upper portion of the seat back frame, the second mounting part connected to the energy attenuating member, and the energy attenuating member interconnects the mounting bracket and the frame backing member.

13. The vehicle assembly of claim 12 , wherein the first mounting part overlies the connection of the energy attenuating member and the second mounting part in the height direction of the vehicle assembly.

14. The vehicle assembly of claim 12 , including a seat back plate secured between the mounting bracket and the seat back frame, the first mounting part connected to the seat back plate.

15. The vehicle assembly of claim 14 , wherein the second mounting part is spaced from the seat back frame via a leg member of the mounting bracket, the leg member positioned beneath the connection of energy attenuating member and the second mounting part in the height direction of the vehicle assembly.

16. The vehicle assembly of claim 12 , wherein the energy attenuating member includes a first wall section and a second wall section separate from the first wall section and looped beneath the first wall section relative to the height direction of the vehicle assembly.

17. The vehicle assembly of claim 16 , wherein the first wall section is interposed between and separates a proximal end portion of the second wall section and a distal end portion of the second wall section in a direction taken from the seat back to the frame backing member.

18. The vehicle assembly of claim 12 , wherein the frame backing member is elongated in a length direction of the vehicle seat, and the vehicle body includes an interior panel sized to cover the space between the seat back frame and the frame backing member, the interior panel including a removable cap providing access to the connection between the first mounting part and the seat back frame.

19. A vehicle assembly comprising:
a vehicle body including a frame backing member;
a seat having a seat base and a seat back connected to the seat base;
an energy attenuating member positioned in a space between an upper portion of a seat back frame and the frame backing member, wherein during a crash event the energy attenuating member is configured to collapse in a height direction of the vehicle assembly between the seat back and the frame backing member to absorb kinetic energy in the vehicle seat when the seat back is driven toward the frame backing member;
a mounting bracket positioned at the upper portion of the seat back frame, the mounting bracket includes a first mounting part and a second mounting part extended from the first mounting part toward the frame backing member, the first mounting part adapted for connection to the upper portion of the seat back frame, the second mounting part connected to the energy attenuating member, and the energy attenuating member interconnects the mounting bracket and the frame backing member; and
a seat back plate secured between the mounting bracket and the seat back frame, the first mounting part connected to the seat back plate.

20. The vehicle assembly of claim 19 , wherein the vehicle body includes an interior panel sized to cover the space between the seat back frame
