[0019] The present invention will be further described below with reference to the following embodiments and accompanying drawings:

[0020] like Figure 1-5The figure shows a lightweight car seat, primarily comprising an integrated seat body 1 manufactured using additive manufacturing. The seat body 1 comprises a seat cushion 1a and a support body 1b, with the seat cushion 1a fully or partially encased within the support body. The seat cushion 1a is configured as a porous or grid-like structure, and the materials used for the seat cushion 1a and the support body 1b are different. The seat cushion 1a primarily serves to reduce shock and provide contact with the human body. Specifically, the seat cushion 1a comprises a seat cushion, backrest, and headrest. The additive manufacturing method employed is 3D printing.

[0021] The support bodies primarily support the entire seat. Specifically, support body 1b comprises a first support body for wrapping the seat cushion, a second support body for wrapping the backrest, a third support body for wrapping the headrest, and a fourth support body for installing the entire seat. The first support body is mounted above the fourth support body via a first connector, the second support body is mounted on the fourth support body via a second connector, and the third support body is mounted on the second support body via a third connector.

[0022] To ensure the strength of the seat cushion, the seat cushion portion 1a is designed as a porous or grid-like structure formed by ribs. These ribs are formed by curing at least two structural materials. Specifically, the ribs include a core and at least one wrapping portion, which can partially or completely surround the core. The core and wrapping portions are manufactured through different curing reactions. The curing reaction can be between different materials or using different curing methods. The curing method can be a polymerization reaction initiated by ultraviolet radiation of different wavelengths or curing achieved by residual thermal energy.

[0023] Therefore, one component of the structural material includes a component that undergoes a curing reaction primarily through thermal curing, such as an oligomer and / or a polymer, and further includes a polyurethane and / or urea and / or at least one epoxy group. The other component includes a component that cures primarily through an autogenous reaction, such as an acrylate, particularly a methacrylate, or contains such a substance.

[0024] Preferably, a coating layer having a heat-insulating function is coated on the outside of the wrapping portion, and the coating layer is partially or completely wrapped around the outside of the wrapping portion.

[0025] When manufacturing the seat cushion, the core is first manufactured, followed by the wrapping, and the coating is applied to the wrapping as needed. The volume of the wrapping can be modified by grinding, polishing, burning, erosion, electron beam, laser, etching, electrolytic removal, and other methods.

[0026] To facilitate seat assembly, an electric turntable 4 is installed beneath the seat body 1 via an upper lap frame 3. Below the electric turntable 4 is a lower lap frame 6, which is mounted on a slide rail assembly 5 or the vehicle body, enabling the seat to slide forward and backward and rotate. Preferably, the upper lap frame 3 is provided with mounting holes that can be directly mounted on the lower lap frame 6, allowing the seat to rotate as needed. Preferably, the electric turntable utilizes a stepless locking mechanism.
