Description

Technical Field

[0001] This invention relates to the field of automotive seat technology, and in particular to a method for installing an automotive seat backrest headrest and logo. Background Technology

[0002] Car headrests are both a driving comfort feature and a safety accessory. In the event of a traffic accident, the immense impact of a collision compresses the vulnerable neck, potentially injuring the spine of the driver and passengers. In severe cases, this can lead to neurological problems, paralysis, or even death. Car headrests are mainly divided into two categories: non-adjustable and adjustable. Commonly used non-adjustable headrests employ an integrated design with the seat back. While this integrated structure offers a more aesthetically pleasing design and greater stability, its installation is more complex, making disassembly and replacement difficult.

[0003] Car logos typically indicate the manufacturer, model, engine power, load capacity, and serial numbers for the engine and the entire vehicle. Traditionally, car logos are installed using adhesive backing, especially on car seat backs. While this method is simple and easy, the bonding strength largely depends on the adhesive properties and aging resistance of the bonding layer. A car can typically be used for several years or even decades, and the adhesive strength of the logo decreases over time, making it difficult to maintain such longevity. Furthermore, exposure to sun and rain during vehicle use further accelerates the decline in adhesive strength, often resulting in logos falling off due to insufficient adhesion. This creates significant problems when the information on the logo needs to be read. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention aims to provide a method for installing a car seat back headrest and logo, so as to solve the problems of difficulty in installing the existing car headrest and logo on the backrest and poor installation stability.

[0005] To achieve the above objectives, this invention proposes a method for installing a car seat backrest, headrest, and logo. The car seat includes a backrest assembly, a headrest assembly, and a logo assembly. The backrest assembly includes backrest foam and a backrest frame. The headrest assembly includes a headrest rod, a front headrest connecting bracket, a rear headrest connecting bracket, an EPP assembly, headrest foam, and headrest soft foam. The logo assembly includes a logo cover and a cover fixing bracket. The installation method includes the following steps:

[0006] S1. Weld the rear connecting bracket of the headrest to the front end of the headrest rod, and weld the cover plate fixing bracket to the rear end of the headrest rod. The cover plate fixing bracket and the rear connecting bracket of the headrest are positioned in a front-to-back correspondence and are both located in the upper middle part of the headrest rod. The headrest rod is in the shape of an "n".

[0007] S2. The headrest rod is pre-installed in the backrest foam and welded to the backrest frame. The backrest foam has a hollow part at the position corresponding to the headrest rear connecting bracket and the cover plate fixing bracket.

[0008] S3. Several bolts are welded to the front connecting bracket of the headrest and foam-molded together with the EPP assembly. The bolts extend out of the EPP assembly.

[0009] S4. Cover the front end face of the EPP assembly with headrest foam, and embed the headrest soft foam into the front end face of the headrest foam. The EPP assembly, headrest foam and headrest soft foam are combined to form the headrest body. Cover the headrest body with a headrest cover. The headrest cover has through holes for bolts to pass through.

[0010] S5. The headrest rear connecting bracket has mounting holes for each bolt to pass through, and the cover plate fixing bracket has clearance holes at the corresponding mounting hole positions. The bolts are passed through the corresponding mounting holes one by one and locked with nuts. The nuts are installed by a nut installation tool passing through the clearance holes from back to front.

[0011] S6. The LOGO cover plate is a plastic part with the LOGO on the back and a number of clips integrally formed on the front. The cover plate fixing bracket has corresponding clip holes for each clip. Each clip has an insert piece that is snapped onto it. The insert piece is an elastic metal part. Each insert piece is snapped into the corresponding clip hole from back to front along with the clip, thereby fixing the LOGO cover plate to the cover plate fixing bracket.

[0012] In the above solution: the three clips are arranged in a triangle on the LOGO cover plate, which helps to ensure the snapping stability of the LOGO cover plate and the cover plate fixing bracket.

[0013] In the above scheme, there are three bolts arranged in a triangle, which helps to ensure the locking effect of the front connecting bracket and the rear connecting bracket of the headrest.

[0014] In the above solution, the headrest soft foam and headrest foam are fixed by adhesive bonding, which makes installation convenient.

[0015] In the above scheme: the top of the headrest rear connecting bracket is welded to the head of the headrest rod, the left and right ends of the headrest rear connecting bracket are welded to the two side legs of the headrest rod, and the headrest rear connecting bracket protrudes forward. The three welding points distributed in a triangle are conducive to ensuring the welding stability of the two. The headrest rear connecting bracket protrudes forward to facilitate better fit with the headrest front connecting bracket.

[0016] In the above scheme: the top of the cover plate fixing bracket is welded to the head of the headrest rod, the left and right ends of the cover plate fixing bracket are welded to the two side legs of the headrest rod, and the cover plate fixing bracket protrudes backward. The three welding points distributed in a triangle are conducive to ensuring the welding stability of the two. The cover plate fixing bracket protrudes forward to facilitate better fit with the LOGO cover plate.

[0017] The beneficial effects of this invention are: 1. Both the headrest assembly and the logo assembly are fixed on the headrest rod, which simplifies the structure and saves time and effort in the entire installation process, greatly improving the production efficiency of car seat backrests; 2. Fixing the headrest rod to the backrest frame and completely encasing it in the backrest foam effectively avoids unnecessary wear caused by the headrest rod being exposed, and also increases the aesthetics and stability of the seat; 3. The logo cover plate is clipped onto the cover plate fixing bracket inside the backrest, and the cover plate fixing bracket is welded to the headrest rod. Compared with traditional adhesive bonding, this can significantly improve the fixing strength and is less likely to loosen over time, meeting the actual need for long-term use without falling off; 4. The cover plate fixing bracket is a metal part, and the clip is a plastic part. A metal connector is provided on the outer sleeve of the clip. When the clip is inserted, the connector contacts the clip hole, avoiding direct contact between the plastic clip and the clip hole, thus effectively preventing breakage when the clip is removed.
