[0035] Please see Figures 1-2 .

[0036] This application discloses a car seat, including a seat basin 1, a seat cushion 2, and side wings 3, wherein the seat cushion 2 and the side wings 3 are both mounted on the seat basin 1. Figure 1 As shown, side wings 3 are provided on both sides of the seat cushion 2. When in use, the seat cushion 2 contacts the user's buttocks, and the side wings 3 contact the outside of the user's thighs and buttocks to wrap around the user's left and right sides.

[0037] In this design, the seat cushion 2 and side wings 3 of the car seat are independent of each other. The seat cushion 2 is fixed to the seat basin 1, and the side wings 3 are installed on the seat basin 1 via an adjustment assembly 4. The height of the side wings 3 is adjusted via the adjustment assembly 4. Figure 1 As shown, the side wing 3 has an arc-shaped convex surface on the side closest to the seat cushion 2. The convex direction of the arc-shaped convex surface is towards the seat cushion 2. The height of the upper end of the side wing 3 is higher than the plane where the seat cushion 2 is located. The arc-shaped convex surface is inclined from bottom to top in the direction away from the seat cushion 2. The horizontal distance between the different positions of the arc-shaped convex surface and the edge of the seat cushion 2 gradually increases from bottom to top.

[0038] Specifically, the side wing 3 moves up and down, and the arc-shaped convex surface of the side wing 3 is flush with the seat cushion 2 at different positions. The horizontal distance between the positions where the arc-shaped convex surface of the two side wings 3 is flush with the seat cushion 2 is the width of the car seat. When the side wing 3 moves downward under the action of the adjustment component 4, the width of the car seat becomes wider. When the side wing 3 moves upward under the action of the adjustment component 4, the width of the car seat becomes narrower.

[0039] The car seat disclosed in this application has a separate structure for the seat cushion 2 and the side wings 3. The side wings 3 can be individually adjusted in height relative to the seat cushion 2 so that different positions of the arc-shaped convex surface of the side wings 3 are flush with the seat cushion 2. This allows the width of the car seat to be adjusted according to the user's body shape, so that people of different body shapes can experience the feeling of being wrapped in the car seat. The car seat meets the comfort needs of people of different body shapes.

[0040] In some embodiments of this application, the adjustment assembly 4 includes a driven gear 41, an arc-shaped rack 42, and a locking member 43. The driven gear 41 is rotatably mounted on the seat 1 and supports and guides the movement of the arc-shaped rack 42. The outer side of the arc-shaped rack 42 is provided with teeth that mesh with the driven gear 41, the inner side of the arc-shaped rack 42 is rotatably connected to the seat cushion 2, the first end of the arc-shaped rack 42 is hinged to the side wing 3, and the second end of the arc-shaped rack 42 is a free end. The locking member 43 is used to lock the driven gear 41 to prevent the driven gear 41 from rotating.

[0041] During adjustment, first release the locking member 43 from locking the driven gear 41, then lift or press down the side wing 3 to adjust the width of the car seat. When the side wing 3 is lifted or pressed down, it will move upward or downward, thereby driving the arc-shaped rack 42 to move. The rack drives the driven gear 41 to rotate. After the width adjustment is completed, the locking member 43 locks the driven gear 41.

[0042] When the side wing 3 is raised, the width of the car seat decreases; when the side wing 3 is lowered, the width of the car seat increases. In this embodiment, the height of the side wing 3 is adjusted by operating the side wing 3, eliminating the need for an external control structure, reducing the structure exposed outside the car seat, and not excessively increasing the overall volume of the car seat.

[0043] In some embodiments, the locking member 43 is a limiting rod, and the length direction of the limiting rod is parallel to the axial direction of the driven gear 41.

[0044] The limiting rod has several movement patterns when locking the driven gear 41. In some embodiments, the movement direction of the limiting rod is perpendicular to the axis of the driven gear 41. The limiting rod moves along the axis of the driven gear 41 towards the driven gear 41, inserting between two adjacent teeth to lock the rotation of the driven gear 41. Alternatively, the limiting rod moves along the axis of the driven gear 41 away from it, separating from the driven gear 41 and releasing the rotational lock on the driven gear 41. In other embodiments, the movement direction of the limiting rod is parallel to the axial direction of the driven gear 41. The limiting rod is located on one side of the axial direction of the driven gear 41. The limiting rod moves towards the driven gear 41 and slides between two adjacent teeth of the driven gear 41 to lock the rotation of the driven gear 41. The limiting rod moves away from the driven gear 41 and separates from the driven gear 41, releasing the rotation lock of the driven gear 41. In this embodiment, the movement direction of the limiting rod is perpendicular to the axial direction of the driven gear 41.

[0045] To further optimize the above technical solution, the automobile seat disclosed in this application also includes a guide structure for guiding the movement of the side wing 3. Specifically, the automobile seat disclosed in this solution also includes a bracket 5, the lower end of which fits against the side of the seat cushion 2, and a guide groove is formed between the upper end of the bracket 5 and the side of the seat cushion 2. The side wing 3 has a guide portion that cooperates with the guide groove, and the guide groove and the guide portion constitute the guide structure. During the process of lifting or pressing down the side wing 3, the guide structure guides the movement of the side wing 3.

[0046] like Figure 2As shown, the side of the seat cushion 2 has a groove, the lower end of the bracket 5 is embedded in the groove, and the upper end of the bracket 5 is located outside the groove. The bracket 5 can support the lower side of the seat cushion 2, enhance the strength of the side of the seat cushion 2, and improve the stability of the movement of the side wing 3.

[0047] Along the plane perpendicular to the seat cushion 2, the side of the bracket 5 is stepped, and the bottom of the bracket 5 is embedded in the groove of the seat cushion 2. The stepped surface of the bracket 5 in the groove is arc-shaped to improve the user's riding comfort. A guide groove is formed between the top of the bracket 5 and the side of the seat cushion 2.

[0048] The part of the seat basin 1 that mates with the side wing 3 is lower than the part of the seat basin 1 that mates with the seat cushion 2, and the lower end of the bracket 5 abuts against the stepped surface of the seat basin 1.

[0049] In some other embodiments of this application (not shown in the figures), the adjustment assembly 4 includes a first gear, a second gear, a screw, and a mounting plate. The axis of the first gear is parallel to the plane where the seat cushion 2 is located. The first gear is connected to the handle. The axis of the second gear is perpendicular to the plane where the seat cushion 2 is located. The first gear meshes with the second gear. The second gear is sleeved on the screw. The mounting plate is connected to the side wing 3. The mounting plate has a threaded hole that mates with the screw.

[0050] The operating handle drives the first gear to rotate, which in turn drives the second gear to rotate, which in turn drives the screw to rotate, causing the mounting plate to raise and lower the side wing 3. The side wing 3 using this adjustment assembly 4 does not require a locking element 43 or a guide structure.

[0051] The car seat disclosed in this solution allows for manual adjustment of the height of the side wings 3 without the need for external power equipment. It is not only simple in structure but also easy to operate, enabling the width-adjustable car seat to be used in mid-to-low-end molding, thereby improving the market competitiveness of mid-to-low-end models.

[0052] The adjustment component 4 is not limited to the two embodiments described above, and may also be other structures, which are not specifically limited here.

[0053] like Figure 2 As shown, the side wing 3 includes an inner frame 31 and a sponge 32. The inner frame 31 is a U-shaped frame, which includes a first side frame, a second side frame, and an arc frame. The first side frame and the second side frame are parallel. The first side frame is closer to the seat cushion 2 than the second side frame. The height of the first side frame is lower than the height of the second side frame. The two ends of the arc frame are connected to the arc frame respectively.

[0054] The U-shaped frame is covered with sponge 32, which supports the sponge 32 to improve the stability and support of the side wings 3.

[0055] The thickness of the sponge 32 can be designed according to the support requirements, and the thickness of the sponge 32 at different locations outside the U-shaped frame can be unequal.

[0056] In this embodiment, the U-shaped frame is connected to the adjustment component 4.

[0057] The car seat disclosed in this solution also includes a backrest and backrest side wings. The backrest side wings are connected to the backrest via an adjustment component 4 to achieve adjustable backrest width.

[0058] The structure of the adjustment component 4 that connects the side wings of the backrest to the backrest can be the same as or different from the structure of the adjustment component 4 that connects the side wings 3 to the seat cushion 2.

[0059] The car seat disclosed in this embodiment not only has an adjustable width for the seat cushion 2 that mates with the user's buttocks and thighs, but also an adjustable width for the backrest that mates with the user's back, so that the width of the seat cushion 2 and the width of the backrest can be adapted to users of different body types, thereby improving the comfort of sitting in the car seat.

[0060] In some embodiments of this application, the sponge of the seat cushion 2 and / or the sponge 32 of the side wing 3 are foamed sponges.

[0061] This solution also discloses a car, including a car seat, wherein the car seat is the car seat described in any of the above solutions.

[0062] Since the car seat has the aforementioned technical effects, the car with the seat also has the same technical effects, which will not be elaborated further here.

[0063] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed, and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. The scope of this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described application concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
