Description

Technical Field

[0001] This utility model relates to an angle-adjustable car seat frame. Background Technology

[0002] Existing car seats generally allow for overall height and fore-aft adjustment, as well as backrest tilt adjustment, achieving two-dimensional adjustment. However, in actual use, especially in the adjustment experience of the front passenger seat, they cannot meet all adjustment needs. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides an angle-adjustable car seat frame.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an angle-adjustable car seat frame, including a seat frame and a backrest unit, wherein the backrest unit is disposed on the seat frame;

[0005] The backrest unit includes a bracket, a column, a backrest frame, a lower locking member, an upper locking member, a nut, and a headrest. The bracket is fixed to the seat frame. The column is vertically mounted on the bracket, with its lower end fixed to the middle of the bracket. The lower locking member, the backrest frame, and the upper locking member are all fitted onto the column. The lower locking member is located below the upper locking member, and the backrest frame is located between the upper and lower locking members. The lower locking member is fixed to the column, and the upper locking member is slidably connected to the column. The lower end of the backrest frame has a limiting groove matching the lower locking member, corresponding to the position of the lower locking member. The upper end of the backrest frame has a groove matching the upper locking member, corresponding to the position of the upper locking member. The nut is threadedly connected to the column and is located above the upper locking member.

[0006] The sides of the upper and lower locking components facing the backrest frame are conical, and anti-slip textures are provided on the conical sides of the upper and lower locking components.

[0007] The headrest is located at the top of the column.

[0008] Preferably, the nut is provided with two drive rods, which are located on both sides of the nut and are on the same straight line.

[0009] Preferably, the headrest is threadedly connected to the column.

[0010] The beneficial effects of this utility model are that the adjustable car seat frame, the connection method between the backrest frame and the upright, allows the backrest frame to rotate around the axis of the upright, and then the backrest frame is locked by two locking parts, realizing the rotational adjustment of the backrest, thereby realizing the three-dimensional adjustment of the backrest and improving the user experience.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] like Figure 1-3 As shown, an angle-adjustable car seat frame includes a seat frame 1 and a backrest unit, wherein the backrest unit is disposed on the seat frame 1.

[0018] The backrest unit includes a bracket 2, a column 3, a backrest frame 9, a lower locking member 4, an upper locking member 5, a nut 6, and a headrest 7. The bracket 2 is fixed on the seat frame 1. The column 3 is vertically arranged on the bracket 2, and the lower end of the column 3 is fixed to the middle of the bracket 2. The lower locking member 4, the backrest frame 9, and the upper locking member 5 are all sleeved on the column 3. The lower locking member 4 is located below the upper locking member 5. The backrest frame 9 is located between the upper locking member 5 and the lower locking member 4. The lower locking member 4 is fixed on the column 3. The upper locking member 5 is slidably connected to the column 3. The lower end of the backrest frame 9 has a limiting groove that matches the lower locking member 4 at the position corresponding to the lower locking member 4. The upper end of the backrest frame 9 has a groove that matches the upper locking member 5 at the position corresponding to the upper locking member 5. The nut 6 is threadedly connected to the column 3 and is located above the upper locking member 5.

[0019] The sides of the upper locking member 5 and the lower locking member 4 facing the backrest frame 9 are conical, and anti-slip textures are provided on the conical sides of the upper locking member 5 and the lower locking member 4.

[0020] The headrest 7 is located at the upper end of the column 3.

[0021] Preferably, the nut 6 is provided with a drive rod 8, and there are two drive rods 8, which are located on both sides of the nut 6 and are on the same straight line.

[0022] Preferably, the headrest 7 is threadedly connected to the column 3.

[0023] Here, the backrest frame 9 is limited by the cooperation of the lower locking part 4, the upper locking part 5, and the nut 6. When adjustment is needed, the nut 6 is loosened by the drive rod 8, and then the upper locking part 5 is pulled up. In this way, the entire backrest frame 9 is no longer locked and can rotate freely around the column 3. When it is rotated to the appropriate position, the upper locking part 5 is pressed into the groove of the backrest frame 9. Since the lower locking part 4 is fixed to the column 3, when the nut 6 is tightened again, the upper locking part 5 and the lower locking part 4 will clamp the backrest frame 9. The conical anti-slip surfaces of the upper locking part 5 and the lower locking part 4 are tightly pressed against the inside of the backrest frame 9. In fact, the backrest frame 9 also has anti-slip surfaces corresponding to the positions of the upper locking part 5 and the lower locking part 4, which can improve the friction and thus achieve stable and reliable adjustment of the backrest frame 9.

[0024] The headrest 7 is located at the top of the column 3. In fact, the headrest 7 is also threadedly connected to the column 3. The height of the headrest 7 can be adjusted by rotating it.

[0025] Compared with existing technologies, this angle-adjustable car seat frame, with its connection method between the backrest frame 9 and the upright column 3, allows the backrest frame 9 to rotate around the axis of the upright column 3, and then locks the backrest frame 9 through two locking parts, thus realizing the rotational adjustment of the backrest and achieving three-dimensional adjustment of the backrest, thereby improving the user experience.

[0026] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
