Abstract

A vehicle body structure includes an interior side wall, a floor structure and an airbag support member. The interior side wall defines a first door opening. The floor structure at least partially defines a passenger compartment of a vehicle along with the interior side wall. The floor structure defines seat supporting section adjacent to the first door opening. The airbag support member has an upper end and a lower end and an airbag attachment portion. The lower end is attached to the interior side wall at a first location above the floor structure between the first door opening and the seat supporting section, the upper end being attached to the interior side wall structure at a second location above the first location.

First claim

What is claimed is:

1. A vehicle body structure, comprising:
an interior side wall defining a first door opening, the interior side wall including a seat supporting bracket installed to the interior side wall at the first location, the seat supporting bracket having a seat hinge pin extending therethrough;
a floor structure at least partially defining a passenger compartment of a vehicle along with the interior side wall, the floor structure defining seat supporting section adjacent to the first door opening; and
an airbag support member having an upper end and a lower end and an airbag attachment portion, the lower end being attached to the interior side wall at a first location above the floor structure between the first door opening and the seat supporting section, the upper end being attached to the interior side wall structure at a second location above the first location, and
a portion of a vehicle seat is pivotally supported by the seat hinge pin.

2. The vehicle body structure according to claim 1 , wherein
the first location and the second location are defined on an upright surface of the interior side wall.

3. The vehicle body structure according to claim 2 , wherein
the upright surface of the interior side wall is inclined relative to horizontal.

4. The vehicle body structure according to claim 2 , wherein
the upright surface of the interior side wall is located along a wheel well section of the interior side wall.

5. The vehicle body structure according to claim 1 , wherein
the seat supporting bracket is welded to the interior side wall.

6. The vehicle body structure according to claim 1 , further comprising
a frame supporting bracket fixedly attached to the seat supporting bracket by the seat hinge pin.

7. The vehicle body structure according to claim 6 , wherein
the frame supporting bracket includes a first attachment flange and a second attachment flange spaced apart from the first attachment flange.

8. The vehicle body structure according to claim 7 , wherein
the first attachment flange and the second attachment flange are angularly offset from one another by between 75 and 105 degrees relative to the seat hinge pin.

9. The vehicle body structure according to claim 8 , wherein
the first attachment flange and the second attachment flange are angularly offset from one another by between 80 and 85 degrees relative to the seat hinge pin.

10. The vehicle body structure according to claim 6 , wherein
the airbag support member includes a rigid wire frame that defines the upper end, the lower end and the airbag attachment portion, the lower end being fixed to the frame supporting bracket.

11. The vehicle body structure according to claim 10 , wherein
the lower end of the rigid wire frame includes a first wire section and a second wire section that are angularly offset from one another by an angle of between 80 and 110 degrees.

12. The vehicle body structure according to claim 11 , wherein
the frame supporting bracket includes a first attachment flange and a second attachment flange spaced apart from and angularly offset from the first attachment flange relative to the seat hinge pin, the first wire section being fixed to the first attachment flange and the second wire section being fixed to the second attachment flange.

13. The vehicle body structure according to claim 1 , wherein
the portion of the vehicle seat is a seatback portion of the vehicle seat movable between an upright orientation and a lowered orientation, the vehicle seat also including a cushion portion that is fixedly attached to the seat supporting section.

14. The vehicle body structure according to claim 13 , further comprising
a divider wall that extends in a vehicle lateral direction from the interior side wall, the divider wall being rearward of the seat supporting section separating the passenger compartment from a cargo area of the vehicle body structure.

15. The vehicle body structure according to claim 14 , further comprising
the divider wall defines an opening that exposes the cargo area of the vehicle with the seatback portion of the vehicle seat in the lowered orientation.

16. The vehicle body structure according to claim 1 , wherein
the seat supporting section of the floor structure includes a front seat supporting section and a rear seat supporting section, and, the first door opening being a rear door opening.

17. The vehicle body structure according to claim 16 , wherein
the side wall structure includes a wheel well and a door sill that extends forward from the wheel well, the door sill at least partially defines the rear door opening.

18. The vehicle body structure according to claim 17 , wherein
the first location and the second location are located on an interior surface of the wheel well vertically higher than the door sill.
