ROTOMOLDED SEAT

1 . A seat assembly comprising:

a rotomolded, compliant base seat member having a wall that defines a first interior chamber;

a rotomolded, compliant back seat member having a wall that defines a second interior chamber; and

a frame attached to the base seat member;

wherein:

the wall of the base seat member contacts the frame; and

a bottom portion of the back seat member is positioned adjacent the base seat member, and the back seat member has an orientation that is transverse to the base seat member.

2 . The seat assembly of claim 1 , wherein the wall of the back seat member contacts the frame, which, supports the base seat member and the back seat member in fixed relative positions.

3 . The seat assembly of claim 1 , wherein the base seat member includes a first port for inflating or deflating the first interior chamber.

4 . The seat assembly of claim 3 , further comprising an air pump fluidically coupled to the first interior chamber and configured to inflate the first interior chamber.

5 . The seat assembly of claim 3 , wherein;

the back seat member includes and a second port for inflating or deflating the second interior chamber; and

the wall of the back seat member contacts the frame.

6 . The seat assembly of claim 5 , including a fluidic coupling between the first and second interior chambers, wherein both the first and second interior chambers are maintained at the same pressure.

7 . The seat assembly of claim 1 , further comprising a rotomolded, compliant headrest member connected to the back seat member adjacent a top portion of the back seat member that is opposite the bottom portion.

8 . (canceled)

9 . The seat assembly of claim 7 , further comprising rotomolded, compliant lateral support members connected to opposing sides of the back seat member and extending between the bottom portion and a top portion of the back seat member, wherein each lateral support member includes an interior cavity defined by a wall, and a port for inflating and deflating the interior cavity of the lateral support member. and the wall of each lateral support contacts the frame.

10 . (canceled)

11 . A seat assembly comprising:

a rotomolded, compliant base seat member having a first interior chamber defined by a wall;

a rotomolded, compliant back seat member adjacent the base seat member and having an orientation that is transverse to the base seat member;

a rotomolded, compliant headrest member connected to the back seat member adjacent a top portion of the back seat member that is opposite the bottom portion;

rotomolded, compliant lateral support members connected to opposing sides of the back seat member and extending between the top and bottom portions; and

a frame in contact with the wall of the base seat member.

12 . The seat assembly of claim 11 , wherein the frame contacts a wall of the back seat member and supports the base seat member and the back seat member in fixed relative positions.

13 . The seat assembly of claim 12 , wherein the headrest member and the lateral support members are each connected to one of the frame and the back seat member.

14 . The seat assembly of claim 11 , wherein the first interior chamber includes a port for inflating and deflating the chamber.

15 . The seat assembly of claim 14 , further comprising an air pump coupled to the port of the first interior chamber.

16 . The seat assembly of claim 14 , wherein at least one of the back seat member, the headrest member and the lateral support members include an interior chamber and a port for inflating and deflating the interior chamber.

17 . The seat assembly of claim 14 , wherein:

the first interior chamber and at least one interior chamber of the back seat member, the headrest member and the lateral support members are fluidically coupled together; and

inflation of one of the interior chambers inflates the other interior chambers.

18 . A method of manufacturing a seat assembly comprising:

forming a base seat member of compliant material using a rotomolding process, the base seat member including an interior chamber defined by a wall;

forming a back seat member of compliant material using a rotomolding process;

connecting the base seat member to a frame, wherein the wall of the base seat member contacts the frame.

19 . The method of claim 18 , further comprising inflating the interior chamber using a pump.

20 . The method of claim 18 , further comprising:

forming at least one of a headrest member and a pair of lateral support members of compliant material using a rotomolding process; and

connecting at least one of the headrest member and the lateral support members to the back seat member.
