Abstract

A seat assembly having a seat bottom and a seat back. The seat bottom may have a pair of side members that are adhered to a seat bottom shell. The seat back may have a pair of brackets that may be adhered to a seat back shell. The seat bottom shell and the seat back shell may be made of carbon fiber.

First claim

What is claimed is:

1 . A seat assembly comprising:
a seat bottom that includes:
a seat bottom shell that is made of carbon fiber and that has a first lateral side wall and a second lateral side wall that is spaced apart from and disposed opposite the first lateral side wall;
a first side member that is adhered to an inboard side of the first lateral side wall that faces toward the second lateral side wall with adhesive; and
a second side member that is adhered to an inboard side of the second lateral side wall that faces toward the first lateral side wall with adhesive, wherein the first side member and the second side member are made of metal; and
a seat back pivotally disposed on the seat bottom, the seat back including:
a seat back shell that is made of carbon fiber;
a first bracket that is adhered to the seat back shell with adhesive; and
a second bracket that is spaced apart from the first bracket and adhered to the seat back shell with adhesive, wherein the first bracket and the second bracket are made of metal.

2 . The seat assembly of claim 1 wherein the first side member includes a first pad disposed proximate a front end of the first side member, a second pad disposed proximate a rear end of the first side member that is disposed opposite the front end, and a third pad that is located between the first pad and the second pad and is spaced apart from the first pad and the second pad, wherein adhesive is disposed on the first pad, the second pad, and the third pad and adheres the first side member to the seat bottom shell.

3 . The seat assembly of claim 2 wherein the third pad has a larger area than the first pad and the first pad has a larger area than the second pad.

4 . The seat assembly of claim 2 wherein the second pad is located under the seat back.

5 . The seat assembly of claim 2 wherein the first pad, the second pad and the third pad each have a plurality of through holes that receive the adhesive.

6 . The seat assembly of claim 2 wherein the first side member has a tilt adjuster opening through which a tilt adjuster mechanism extends, wherein the first pad and the third pad are disposed on opposite sides of the tilt adjuster opening.

7 . The seat assembly of claim 6 wherein the first side member has a first lower mounting hole and a second lower mounting hole that facilitate mounting of a lower recliner mechanism bracket that extends from a recliner mechanism, wherein the second pad and the third pad are disposed on opposite sides of the first lower mounting hole.

8 . The seat assembly of claim 7 wherein the second pad is laterally disposed between the inboard side of the first lateral side wall and the lower recliner mechanism bracket such that the second pad is spaced apart from the lower recliner mechanism bracket.

9 . The seat assembly of claim 2 wherein a seat track assembly is mounted to the first side member between the second pad and the third pad.

10 . A seat assembly comprising:
a seat bottom that includes:
a seat bottom shell that is made of carbon fiber;
a first side member that adhered to the seat bottom shell with adhesive; and
a second side member that is disposed opposite the first side member and adhered to the seat bottom shell with adhesive, wherein the first side member and the second side member are made of metal; and
a seat back pivotally disposed on the seat bottom, the seat back including:
a seat back shell that is made of carbon fiber and that has a back panel, a first side wall that extends forward from the back panel, and a second side wall that extends forward from the back panel and is spaced apart from and disposed opposite the first side wall;
a first bracket that is adhered to the back panel and the first side wall with adhesive; and
a second bracket that is spaced apart from the first bracket and adhered to the back panel and the second side wall with adhesive, wherein the first bracket and the second bracket are made of metal.

11 . The seat assembly of claim 10 wherein the first bracket has a first bracket pad that is spaced apart from the first side wall and a second bracket pad that is spaced apart from the first bracket pad, wherein the first bracket pad and the second bracket pad are adhered to the seat back shell.

12 . The seat assembly of claim 11 wherein the first bracket has a third bracket pad that is spaced apart from the first bracket pad and the second bracket pad, wherein the adhesive adheres the second bracket pad and the third bracket pad to the first side wall and the third bracket pad is disposed closer to the seat bottom than the second bracket pad.

13 . The seat assembly of claim 12 wherein the second bracket pad and the third bracket pad are spaced apart from the back panel.

14 . The seat assembly of claim 12 wherein the first bracket pad has a larger area than the second bracket pad and the second bracket pad has a larger area than the third bracket pad.

15 . The seat assembly of claim 12 wherein the first bracket pad, the second bracket pad, and the third bracket pad each have a plurality of through holes that receive the adhesive.

16 . The seat assembly of claim 12 wherein the first bracket has an intermediate portion that has a first upper mounting hole and a second upper mounting hole that facilitate mounting of an upper recliner mechanism bracket that extends from a recliner mechanism, wherein the second bracket pad and the third bracket pad are disposed on opposite sides of the intermediate portion.

17 . The seat assembly of claim 16 wherein the first side wall of the seat back shell has a hole that receives the recliner mechanism and the third bracket pad is disposed adjacent to the hole and extends partially around the hole.

18 . The seat assembly of claim 16 wherein the second bracket pad is disposed closer to a center plane of the seat back than the third bracket pad.

19 . The seat assembly of claim 16 wherein the first bracket has a first step that extends from the second bracket pad to the intermediate portion and a second step that extends from the third bracket pad to the intermediate portion, wherein the intermediate portion is laterally offset from the second bracket pad and the third bracket pad.

20 . The seat assembly of claim 19 wherein a connecting arm extends from the first bracket pad to the intermediate portion and the third bracket pad.
