Abstract

A frame structure to be provided in a seat back having a seatbelt retractor and a seatbelt guide at a top of a seat, wherein the frame structure is an integral structure including an oblique frame obliquely extending upwardly to a seatbelt guide installation section from a first support point located at an end side of a lower part of the seat back in a seat width direction, a vertical frame extending upwardly from a second support point located at another end side of the lower part of the seat back in the seat width direction and connects to the oblique frame at a top, and a transverse frame extending between a lower end of the oblique frame and a lower end of the vertical frame.

First claim

The invention claimed is:

1. A frame structure to be provided in a seat back having a seatbelt retractor and a seatbelt guide at a top of a seat, wherein the frame structure is an integral structure comprising:
an oblique frame obliquely extending upwardly to a seatbelt guide installation section from a first support point located at an end side of a lower part of the seat back in a seat width direction, and having a core member made of a foam material in at least a part of a cross section thereof, and a U-shaped cross section,
a vertical frame extending upwardly from a second support point located at another end side of the lower part of the seat back in the seat width direction and connects to the oblique frame at a top,
a transverse frame extending between a lower end of the oblique frame and a lower end of the vertical frame.

2. The frame structure according to claim 1 , wherein the oblique frame comprises a plate section in a seat front side facing to a seat front-rear direction and another plate section in a lateral side facing to the seat width direction.

3. The frame structure according to claim 1 , wherein the vertical frame has a plate section in the lateral side facing to the seat width direction.

4. The frame structure according to claim 2 , wherein the transverse frame comprises a plate section in a bottom side facing to a seat vertical direction and another plate section in a front side facing to the seat front-rear direction and connects to the plate section in the oblique frame facing to the seat front-rear direction at the lower end of the oblique frame.

5. The frame structure according to claim 1 , wherein the oblique frame and/or the transverse frame have a reinforcing rib.

6. The frame structure according to claim 1 , wherein the frame structure has a reinforcing frame extending between the oblique frame and the vertical frame.

7. The frame structure according to claim 1 , wherein the frame structure has a reinforcing frame extending between the oblique frame and the transverse frame.

8. The frame structure according to claim 1 , wherein the frame structure has a reinforcing frame extending between the transverse frame and the vertical frame.

9. The frame structure according to claim 1 , wherein at least a part of the frame structure is made of a resin.

10. The frame structure according to claim 1 , wherein at least a part of the frame structure is made of a fiber reinforced resin.

11. The frame structure according to claim 10 , wherein at least a part of the oblique frame is made of the fiber reinforced resin.

12. The frame structure according to claim 1 , wherein at least a part of the frame structure is pasted with a fiber reinforced resin tape in which reinforcing fibers are unidirectionally-oriented.

13. The frame structure according to claim 1 , wherein the frame structure is provided inside a tiltable seat back.
