Description

Technical Field

[0001] The utility model relates to the technical field of automotive seat headrests, and particularly to an automotive seat headrest. Background Art

[0002] In order to meet the styling requirements of the seat headrest, it is necessary to design the two sides of the headrest to be concave, and the appearance of the concave shape needs to be smooth and without wrinkles to achieve the design requirements. The traditional headrest has no styling on the side, and the bottom is fixed with a clamping strip. Due to the use of the clamping strip fixing form, the clamping strip has a certain thickness, and it is easy to produce protrusions on the appearance. Therefore, the current connection method of the cover cannot meet the design requirements of having a certain concavity and a wrinkle-free appearance. Summary of the Utility Model

[0003] In view of the above problems, the purpose of the utility model is to provide an automotive seat headrest for fixing the headrest cover, achieving a concave effect, a smooth appearance, and no wrinkles, and meeting the design requirements to overcome the above-mentioned deficiencies of the prior art.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An automotive seat headrest includes: a headrest skeleton, a headrest foam, and a headrest cover;

[0006] Among them, the headrest skeleton includes: a headrest rod fixedly connected to the seat, a rear skeleton fixedly connected to the headrest rod, a front skeleton snap-connected to the rear skeleton, side ear skeletons installed on both sides of the front skeleton and the rear skeleton, and a cover skeleton snap-connected to the side ear skeletons;

[0007] Among them, the headrest foam is in a C shape, a positioning block is arranged at the upper end of the inner side of the headrest foam, and the headrest foam is snap-connected to the outside of the front skeleton;

[0008] Among them, the headrest cover includes: a main cut piece skin enclosing an ellipse, and auxiliary cut piece skins located on both sides of the main cut piece skin.

After the headrest cover 3 is installed, the assembly of the front skeleton 103 and the rear skeleton 102 is completed (the connection method is clamping). Then install the side ear skeleton 104 on the side (the connection methods are clamping and bolt connection). After the side ear skeleton 104 is installed, put the assembly holes on the secondary cut piece skin 302 on the side of the headrest cover 3 over the fixing claws on the side ear skeleton 104. Finally, assemble the cover skeleton 105 onto the side ear skeleton 104 (the connection method is clamping) to complete the overall assembly.

[0042] The working process includes the following steps:

[0043] Step S1: Assemble the headrest rod 101 onto the bottom of the rear skeleton 102 to form a first assembly unit after connection; refer to Figure 12 .

[0044] Step S2: Install the headrest foam 2 onto the front skeleton 103, and dock the positioning shaped block 201 of the headrest foam 2 with the shaped groove 106 on the front skeleton 103 to form a second assembly unit after connection; refer to Figure 13 .

[0045] Step S3: Pre-assemble the first assembly unit and the second assembly unit. The pre-assembly is to first clamp the upper ends of the front skeleton 103 and the rear skeleton 102; refer to Figure 14 .

[0046] Step S4: After the pre-assembly is completed, the main cut piece skin 301 of the headrest facia 3 is assembled on the front frame 103 and the rear frame 102. After the facia assembly is completed, the lower ends of the front frame 103 and the rear frame 102 are snap-connected and fixed; after fixation, a third assembly unit is formed; refer to Figure 17 。

[0047] Step S5: The two side ear frames 104 are installed under the skin hem on both sides of the third assembly unit and are connected and fixed with screws. After the side ear frame 104 is assembled, a set of second fixing holes 309 on the secondary cut piece skin 302 are respectively sleeved on the third fixing hooks 113 on the side ear frame 104 to form a fourth assembly unit; refer to Figure 18 。

[0048] Step S6: The fourth snap hooks 115 of the two cover frames 105 are snap-connected with the second docking slots 114 of the two side ear frames 104 to form a headrest assembly unit, refer to Figure 2 。
