摘要：

A seat structure including at least one frame having one or more thin walled complex geometry structures and a process for forming the at least one frame via an additive manufacturing process.

技术问题语段：

The technical problem of the patent text is that conventional seat structures are made with many components that are assembled in a way that makes them heavier and more complex than necessary. This is because each component is designed to perform one or more functions.

技术功效语段：

The invention provides a seat that is durable, strong, and light.

权利要求：

1. A seat (45), comprising: a structural frame (1, 1') comprising one or more thin walled complex geometry structures (3, 3'), said one or more thin walled complex geometry structures (3, 3') comprising one or more of multiple internal channels (41, 43) and ribs (5), said one or more of multiple channels (41, 43) and ribs (5) defining a structure for supporting elements within said structural frame (1, 1'), said one or more of said multiple channels (41, 43) and said ribs (5) defining one or more of structural loading paths and a channel (43) for one or more of transporting fluids and receiving one or more components (31), wherein said structural frame (1, 1') comprises one or more of a seat back and a cushion frame comprising additive manufacturing material, said one or more thin walled complex geometry structures (3, 3') comprising non-castable and non-machinable portions. 2. A seat (45) in accordance with claim 1, wherein said structure for supporting elements within said structural frame (1, 1') comprises a first component (33) and a second component (35), said first component defining an interior space (27), said second component being located in said interior space (27). 3. A seat (45) in accordance with one or more of claims 1-2, wherein said first component (33) is connected to said second component (35) via said ribs (5). 4. A seat (45) in accordance with one or more of claims 1 - 3, wherein said first component (33) and said second component (35) define said channel (41, 43), said second component (35) comprising a second component channel (41). 5. A seat (45) in accordance with one or more of claims 1-4, wherein said channel (43) defines a fluid flow path (51), wherein a wire harness is arranged in said second component channel (41). 6. A seat (45) in accordance with one or more of claims 1-5, wherein the structural frame (1, 1') is formed in one piece by an additive manufacturing process. 7. A seat (45) in accordance with claim 6, wherein the structural frame (1, 1') is formed in one piece by a three-dimensional printing process.
