Abstract
Seat assemblies (200) including structural components (212, 222, 232) made of foam are described. A seat sub-assembly (210, 220, 230) can include a frame (214, 224, 234) and a foam support (212, 222, 232). The foam support (212, 222, 232) can be coupled to the frame (214, 224, 234) for receiving a load on the seat sub-assembly (210, 220, 230), dissipating at least half of the load, and dispersing the load through the frame (214, 224, 234).
Claims7
A seat assembly comprising:
- a seat pan comprising:
- a bottom frame;
- and
- a bottom support coupled to the bottom frame for bearing at least half of a first load on the seat assembly and dispersing a portion of the first load across the bottom support to the bottom frame;
- a seat back coupled to the seat pan, the seat back comprising:
- a back frame;
- and
- a back support coupled to the back frame for bearing at least half of a second load on the seat assembly and for dispersing a portion of the second load across the back support to the back frame;
- and
- a leg rest coupled to the seat pan, the leg rest comprising:
- a leg frame;
- and
- a leg support coupled to the leg frame for bearing at least half of a third load on the seat assembly and for dispersing a portion of the third load across the leg support to the leg frame, and
- wherein the bottom support, the back support, and the leg support each include a load-bearing foam for receiving a corresponding load, dissipating at least half of the load, and dispersing a portion of the load through the corresponding frame,
- wherein the back frame defines a back-receiving area, wherein the foam of the back support is positioned within the back-receiving area, wherein the foam of the back support is larger than the back-receiving area, and wherein the back frame is positioned in a groove in the foam of the back support,
- wherein the leg frame defines a leg-rest area, wherein the foam of the leg support is positioned within the leg-rest area, wherein the foam of the leg support is larger than the leg-rest area, and wherein the leg frame is positioned in a groove in the foam of the leg support, and
- wherein the bottom frame comprises four frame segments defines a sitting area, wherein the foam of the bottom support is positioned within the sitting area, wherein the foam of the bottom support is larger than the sitting area, and wherein each of the four frame segments of the bottom frame are encompassed by the foam of the bottom support.
