Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a double-layer seat cushion installation support structure. Background Art

[0002] As people's demands for car seat comfort and functionality continue to rise, some large SUVs and commercial vehicles have introduced large bed rest modes to facilitate reclining and resting. In the current automotive industry, reclining and resting functions are usually achieved in the following ways: one is to lay the seat back flat, and the other is to assemble multiple seats together. Obviously, the former has a shorter bed structure and cannot accommodate users of different body shapes, while the latter is cumbersome to operate and the assembled bed is less comfortable.

[0003] To address these needs, companies are actively developing technologies that can transform entire chairs into beds. The current main concept involves creating a double-layered seat cushion structure, which can be flipped and unfolded to expand the surface area, thereby ensuring the feasibility of converting the chair into a bed. However, within this research and development process, ensuring that the double-layered seat cushion provides excellent support and comfort both in a normal sitting position and when flipped and unfolded into a bed remains a pressing technical challenge.

[0022] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0023] like Figures 1 to 3 As shown, a double-layer seat cushion mounting support structure includes a first support frame 1, a second support frame 2, and a support base 3 arranged in sequence from top to bottom. The first support frame 1 can switch between being stacked on the second support frame 2 and flipped backward to a horizontal position relative to the second support frame 2. A support plate 4 is laid on the upper side of the second support frame 2, and the lower side of the second support frame 2 is fixedly connected to the support base 3. Figure 5 and 6 As shown, the first supporting frame 1 and the second supporting frame 2 are both covered with foam and a face cover a.

[0024] Based on the above structural design, the double-layer seat cushion mounting support structure is applied to a car seat. When the seat is in the seated position, the first support frame 1 and the second support frame 2 overlap to form the seat cushion as a whole. By laying the support plate 4 on the second support frame 2, it can provide stable support for the user and ensure the user's riding comfort. When the first support frame 1 is flipped backward to a horizontal position relative to the second support frame 2 to expand the support area for the user to lie down and rest, the support plate 4 can keep the outer upper surface of the second support frame 2 flat, thereby ensuring the user's comfort when lying down, and has the advantages of good support and excellent comfort.

[0025] In this embodiment, the support plate 4 is a resilient plastic plate. With this design, when the seat is in a sitting position, the support plate 4 can provide elastic support for the seat cushion, improving the user's normal riding comfort. Furthermore, when the first support frame 1 is flipped back to a horizontal position relative to the second support frame 2, the resilient support plate 4 can improve the user's comfort when lying flat.

[0026] Please refer to Figure 1 and 4 The second support frame 2 includes a rectangular frame 2a, and a crossbeam 2b is provided near the front of the rectangular frame 2a. The crossbeam 2b is fixedly assembled on the support base 3 through two downwardly extending supports 2c. Figure 3As shown, the rear end of the rectangular frame 2a is provided with a connecting seat 2d extending forward. The connecting seat 2d is connected to the support base 3 via a transverse tube 2e. To ensure the stability of the connection between the rectangular frame 2a and the support base 3, in this embodiment, there are two groups of connecting seats 2d, which are arranged symmetrically along the width of the rectangular frame 2a.

[0027] Re-attend Figure 1 and Figure 3 In this embodiment, the first supporting frame 1 is a rectangular frame, and first mounting seats 1a are provided on both sides of the rear end of the first supporting frame 1, and second mounting seats 2f are provided on both sides of the rear end of the second supporting frame 2. On the same side, the first mounting seat 1a and the second mounting seat 2f are rotatably connected to ensure that the first supporting frame 1 can be flipped backward relative to the second supporting frame 2.

[0028] Furthermore, Figure 1 and 3 As shown, a transition component 5 is provided between the first mounting seat 1a and the second mounting seat 2f, and the two ends of the transition component 5 are rotatably connected to the first mounting seat 1a and the second mounting seat 2f respectively, so that the first support frame 1 can switch between being stacked on the second support frame 2 and flipped backward relative to the second support frame 2 to a horizontal posture.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present invention.
