Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive seat technology, and in particular to an automotive seat that combines comfort adjustment and folding storage. Background Technology
[0002] During the development of seats, mainstream five-link zero-gravity seats have limitations such as high price, complex structure, and large space occupation. Moreover, the complex linkage mechanism leads to a high failure rate, and the single rotation of the seat cushion cannot effectively support the thighs. In addition, traditional seats that can be folded for storage often occupy a large space themselves. For example, the back of the seat cushion of a foldable stowable seat occupies a large Z-axis space, making it impossible to achieve a low block value. Similarly, for seats where the seat cushion does not sink but the backrest can be laid flat, the height of the backrest rotation center needs to be set very high, which occupies a large space itself, ultimately resulting in a small storage space when the backrest is laid flat.
[0003] Therefore, a car seat that combines comfortable adjustment with folding storage is needed to improve the above problems. Utility Model Content
[0004] To address the aforementioned problems in the prior art, this utility model provides a car seat that combines comfort adjustment and folding storage, which is low in cost, occupies little space, has a simple layout, improves seating comfort, and expands storage space.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A car seat that combines comfort adjustment and folding storage includes a backrest, a seat frame, a base, an adjustment motor, an adjuster assembly, and a crank. The backrest is connected to the rear of the base or directly fixed to the vehicle body. The rear of the seat frame slides into a groove in the base via a slider. The front of the seat frame is connected to the upper end of the crank. The lower end of the crank is connected to the front end of the base via the adjuster assembly. The adjustment motor is fixed to the base or the vehicle body and connected to the adjuster assembly via a lead screw.

This utility model provides a car seat that combines comfort adjustment and folded storage, including a backrest 1, a seat frame 2, a base 3, an angle adjustment motor 4, an angle adjuster assembly 5, a crank 6, and a crossbar 7. The backrest 1 is connected to the rear side of the base 3 or directly fixed to the vehicle body. The base 3 is directly or via a slide rail fixed to the vehicle body. The rear part of the seat frame 2 slides in conjunction with the slide groove 31 of the base 3 via a slider 21. The slide groove 31 is symmetrically arranged at the rear of the base 3. A slider 21 is symmetrically arranged at the rear of the seat frame 2. The slider 21 slides in the slide groove 31, which serves both guiding and limiting functions. The seat frame 2 and the base 3 are preferably made of magnesium alloy. The front of the seat frame 2 is connected to the upper end of the crank 6, and the lower end of the crank 6 is connected to the front end of the base 3 via an angle adjuster assembly 5. That is, the two ends of the crank 6 are respectively connected to the front of the seat frame 2 and the front end of the base 3. The rotation range of the crank 6 is 30-120°. The angle adjusting motor 4 is fixed to the base 3 or the vehicle body and connected to the angle adjuster assembly 5 via a lead screw 41. In a preferred embodiment, a horizontal tube 7 is provided between the upper ends of the two cranks 6, and the horizontal tube 7 is connected to the seat frame 2.
[0029] The following will refer to Figures 1 to 6 The working principle of this utility model will be explained.
[0030] Comfort adjustment: The rotation of the angle adjustment motor 4 drives the lead screw 41 to rotate, the rotation of the lead screw 41 drives the angle adjuster assembly 5 to rotate, the rotation of the angle adjuster assembly 5 drives the crank 6 to rotate, and the front side of the seat frame 2 moves due to the rotation of the crank 6. The rear side of the seat frame 2 slides in the slide groove 31 on the base 3 through the slider 21, so that the movement of the seat frame 2 presents the front side lifting and the whole body translation, thereby realizing the function of seat cushion angle adjustment and improving the seat comfort.
[0031] Folding storage adjustment: The motor 4 continues to rotate, causing the crank 6 to rotate forward after passing around the vertical plane, until the slider 21 in the seat frame 2 slides to the front end of the slide groove 31. At this time, the seat frame 2 sinks to the limit and remains there, and the backrest 1 can be folded forward and laid flat, expanding the storage space.
[0032] This utility model discloses a car seat that combines comfort adjustment and folding storage. Compared with a five-link structure, it has fewer parts and lower space occupancy. A single motor drives multi-degree-of-freedom movement to achieve seat cushion angle adjustment, improving human comfort and reducing fatigue. It is low in cost, occupies little space, has a simple layout, and improves the overall coordination of seat adjustment. The crank-slider linkage structure enables multi-mode movement of the seat cushion, achieving a zero-gravity sitting posture while simplifying the structure. The magnesium alloy base and seat frame also reduce the weight of the seat. When the seat cushion angle is adjusted to the limit, it can achieve the function of folding down the seat cushion. The backrest can be folded forward and laid flat without affecting the seat cushion, expanding the storage space and improving space utilization.
[0033] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
