Abstract

A seat back assembly including a pultrusion reinforcement and a seat back frame formed of a resin material, the seat back frame is only partially overmolded onto the pultrusion reinforcement such that the pultrusion reinforcement is configured to be visually inspected through a plurality of openings formed in the seat back frame.

First claim

What is claimed is:

1. A seat back assembly comprising:
a pultrusion reinforcement having a generally hat shape formed by a base wall, a pair of side walls that extend from side edges of the base wall, and a pair of flanges that extend from side edges of the pair of side walls; and
a seat back frame formed of a resin material, the seat back frame is only partially overmolded onto the pultrusion reinforcement such that the pultrusion reinforcement is configured to be visually inspected through a plurality of apertures and a plurality of slots formed in the seat back frame.

2. The seat back assembly of claim 1 , wherein the pultrusion reinforcement is formed of a continuous glass fiber reinforced resin material.

3. The seat back assembly of claim 1 , wherein the plurality of apertures are formed in the seat back frame such that a portion of the base wall of the pultrusion reinforcement is configured to be visually inspected through the plurality of apertures,
wherein the plurality of apertures are formed in the seat back frame such that a portion of at least one of the pair of side walls is configured to be visually inspected through the plurality of apertures.

4. The seat back assembly of claim 3 , wherein the seat back frame includes a first surface and an opposite second surface and the pultrusion reinforcement is positioned between the first surface and the second surface of the seat back frame, and
wherein the plurality of apertures and the plurality of slots are formed in both the first surface and the second surface.

5. The seat back assembly of claim 4 , wherein the second surface of the seat back frame includes a plurality of reinforcement ribs that extend along a plurality of link portions formed in the second surface of the seat back frame, the plurality of link portions define the plurality of apertures formed in the second surface of the seat back frame.

6. A seat back assembly comprising:
a pultrusion reinforcement having a generally double hat shape formed by an upper flange, an upper base wall, a center wall, a first upper side wall extending between the upper flange and the upper base wall, a second upper side wall extend between the upper base wall and the center wall, a lower base wall, a lower flange, a first lower side wall that extends between the center wall and the lower base wall, and a second lower side wall that extends between the lower base wall and the lower flange; and
a seat back frame formed of a resin material, the seat back frame is only partially overmolded onto the pultrusion reinforcement such that the pultrusion reinforcement is configured to be visually inspected through a plurality of openings formed in the seat back frame.

7. The seat back assembly of claim 6 , wherein the plurality of openings includes a plurality of upper apertures, a plurality of lower apertures, a plurality of upper slots, a plurality of lower slots, and a plurality of intermediate slots,
wherein the plurality of upper apertures are formed in the seat back frame such that a portion of the upper base wall of the pultrusion reinforcement is configured to be visually inspected through the plurality of upper apertures,
wherein the plurality of lower aperture are formed in the seat back frame such that a portion of the lower base wall of the pultrusion reinforcement is configured to be visually inspected through the plurality of lower apertures,
wherein the plurality of upper slots are formed in the seat back frame such that at least a portion of the first upper side wall of the pultrusion reinforcement is configured to be visually inspected through the plurality of upper slots,
wherein the plurality of lower slots are formed in the seat back frame such that at least a portion of the first lower side wall of the pultrusion reinforcement is configured to be visually inspected through the plurality of lower slots, and
wherein the plurality of intermediate slots are formed in the seat back frame such that at least a portion of the center wall of the pultrusion reinforcement is configured to be visually inspected through the plurality of intermediate slots.

8. The seat back assembly of claim 7 , wherein the seat back frame includes a plurality of upper reinforcement ribs and a plurality of lower reinforcement ribs, the plurality of upper reinforcement ribs are configured to be positioned between the first upper side wall and the second upper side wall of the pultrusion reinforcement, and the plurality of lower reinforcement ribs are configured to be positioned between the first lower side wall and the second lower side wall of the pultrusion reinforcement.

9. A seat assembly comprising:
a seat cushion frame;
a pultrusion reinforcement having at least one generally hat shape formed by a base wall, a pair of side walls that extend from side edges of the base wall, and a pair of flanges that extend from side edges of the pair of side walls; and
a seat back frame formed of a resin material, the seat back frame is only partially overmolded onto the pultrusion reinforcement such that the pultrusion reinforcement is configured to be visually inspected through a plurality of apertures and a plurality of slots formed in the seat back frame.

10. The seat assembly of claim 9 , wherein the pultrusion reinforcement is formed a continuous glass fiber reinforced resin material.

11. The seat assembly of claim 9 , wherein the plurality of apertures are formed in the seat back frame such that a portion of the base wall of the pultrusion reinforcement is configured to be visually inspected through the plurality of apertures,
wherein the plurality of apertures are formed in the seat back frame such that a portion of at least one of the pair of side walls is configured to be visually inspected through the plurality of apertures.

12. The seat assembly of claim 11 , wherein the seat back frame includes a first surface and an opposite second surface and the pultrusion reinforcement is positioned between the first surface and the second surface of the seat back frame, and
wherein the plurality of apertures and the plurality of slots are formed in both the first surface and the second surface.

13. The seat assembly of claim 12 , wherein the second surface of the seat back frame includes a plurality of reinforcement ribs that extend along a plurality of link portions formed in the second surface of the seat back frame, the plurality of link portions to define the plurality of apertures formed in the second surface of the seat back frame.

14. The seat assembly of claim 9 , wherein the at least one generally hat shape of the pultrusion reinforcement is a generally double hat shape, wherein the pair of flanges includes an upper flange and a center wall, and the pair of side walls includes a first upper side wall and a second upper side wall, wherein the generally double hat shape is formed by the base wall, the center wall, the first upper side wall extending between the upper flange and the base wall, the second upper side wall extending between the base wall and the center wall, a lower base wall, a lower flange, a first lower side wall that extends between the center wall and the lower base wall, and a second lower side wall that extends between the lower base wall and the lower flange.

15. The seat assembly of claim 14 , wherein the plurality of openings includes a plurality of upper apertures, a plurality of lower apertures, a plurality of upper slots, a plurality of lower slots, and a plurality of intermediate slots,
wherein the plurality of upper apertures are formed in the seat back frame such that a portion of the base wall of
