[0003] In view of the above problems, the purpose of the utility model is to provide a seat cushion lifting mechanism for an automobile seat with a rear seat folding mechanism, which is used to lift the height of the seat cushion so that it is flush with the folded seat back, in order to overcome the above-mentioned deficiencies of the prior art.
[0004] A seat cushion lifting mechanism for an automobile seat with a rear seat folding mechanism provided by the utility model includes: a seat back frame with a folding function, the bottom of the seat back frame is rotatably connected to the seat cushion frame assembly through an angle adjuster, the seat back frame is folded backward through the angle adjuster, a lower connecting plate of the angle adjuster is installed at a position near the angle adjuster at the bottom of the seat back frame, and the lower connecting plate of the angle adjuster is connected to the seat cushion lifting mechanism and drives the seat cushion to lift and lower; the seat cushion lifting mechanism is used to automatically adjust the seat cushion frame to be flush with the folded seat back frame, and the seat cushion lifting mechanism includes: a movable seat cushion frame, the rear end of the movable seat cushion frame is hinged to a seat cushion adjustment rotating shaft on the lower connecting plate of the angle adjuster, the front end of the movable seat cushion frame is fixedly connected with a sliding rotating shaft, a strip-shaped sliding hole is formed in a seat cushion fixing seat below the movable seat cushion frame, and the sliding rotating shaft of the movable seat cushion frame is slidably connected in the strip-shaped sliding hole of the seat cushion fixing seat. During the process of the seat back frame being folded backward, the lower end of the lower connecting plate of the angle adjuster is driven to rotate forward around the angle adjuster rotating shaft, the seat cushion adjustment rotating shaft on the lower connecting plate of the angle adjuster drives the rear end of the movable seat cushion frame to be lifted upward and flush with the folded seat back frame, and at the same time, the front end of the movable seat cushion frame moves forward on the seat cushion fixing seat through the sliding rotating shaft, so that the movable seat cushion frame is flush with the folded seat back frame.
[0005] The beneficial effects of the utility model are as follows:
[0006] 1. In view of the problem that the seat cushion cannot be flush with the reclined seat backrest frame after the seat backrest frame is reclined, which affects the lying comfort, the present utility model makes the seat cushion frame automatically adjust to a position flush with the reclined seat backrest frame by adding a seat cushion lifting mechanism, thereby improving the lying experience.
[0007] 2. The seat cushion lifting mechanism of the present utility model can automatically adjust the height following the seat backrest frame, thereby improving the operation portability. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] By referring to the following description in conjunction with the drawings, and with a more comprehensive understanding of the present utility model, other objects and results of the present utility model will become more apparent and easier to understand. In the drawings:
[0009] Figure 1 is a schematic diagram of the overall structure of the seat cushion lifting mechanism before lifting in this embodiment.
[0010] Figure 2 is a schematic diagram of the overall structure of the seat cushion lifting mechanism after lifting in this embodiment.
[0011] The reference numerals therein include: seat backrest frame 1, angle adjuster 2, seat cushion fixing seat 3, seat cushion lifting mechanism 4, movable seat cushion frame 401, seat cushion adjusting rotating shaft 402, sliding rotating shaft 403, strip-shaped sliding hole 404, lower connecting plate 5 of the angle adjuster, and angle adjuster rotating shaft 6. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0012] Embodiment 1
[0013] Referring to Figure 1-2 As shown, a seat cushion lifting mechanism for an automotive seat with a rear seat reclining mechanism provided in this embodiment includes: a seat backrest frame 1 with a reclining function, the bottom of the seat backrest frame 1 is rotatably connected to the seat cushion fixing seat 3 of the seat cushion frame assembly through an angle adjuster 2, the seat backrest frame 1 is reclined backward through the angle adjuster 2, a lower connecting plate 5 of the angle adjuster is installed at a position near the angle adjuster 2 at the bottom of the seat backrest frame 1, and the lower connecting plate 5 of the angle adjuster is connected to the seat cushion lifting mechanism 4 and drives the seat cushion to lift and lower; the seat cushion lifting mechanism 4 is used to automatically adjust the movable seat cushion frame 401 of the seat cushion frame assembly to be flush with the reclined seat backrest frame 1; the seat cushion lifting mechanism 4 includes: a movable seat cushion frame 401, the rear end of the movable seat cushion frame 401 is hinged to the seat cushion adjusting rotating shaft 402 on the lower connecting plate 5 of the angle adjuster, the front end of the movable seat cushion frame 401 is fixedly connected with a sliding rotating shaft 403, a strip-shaped sliding hole 404 is formed on the seat cushion fixing seat 3 below the movable seat cushion frame 401, and the sliding rotating shaft 403 of the movable seat cushion frame 401 is slidably connected in the strip-shaped sliding hole 404 of the seat cushion fixing seat 3.
[0014] Working process: During the backward reclining process of the seat backrest frame 1, the lower end of the lower connecting plate 5 of the angle adjuster is driven to rotate forward around the angle adjuster rotating shaft 6. The seat cushion adjusting rotating shaft 402 on the lower connecting plate 5 of the angle adjuster drives the rear end of the movable seat cushion frame 401 to lift upward (in the Z direction) and be flush with the reclined seat backrest frame 1. At the same time, the front end of the movable seat cushion frame 401 moves forward on the seat cushion fixing seat 3 through the sliding rotating shaft 403, so that the movable seat cushion frame 401 is flush with the reclined seat backrest frame 1.
[0015] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
