Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to a wiring harness shielding structure for automotive seat backrest covers. Background Technology

[0002] As car seats become increasingly feature-rich, including functions such as seat heating, ventilation, massage, and airbag deployment, the number of wiring harnesses required for connection and control has also increased. Currently, the main bus outlets of automotive wiring harnesses are located on both sides of the bottom of the seat back. However, during the adjustment process of traditional car seat backs, there is a risk that the internal foam components may be exposed at certain angles due to a height difference between the two sides of the backrest after the wiring harness is installed. Summary of the Invention

[0003] In view of the above problems, the purpose of this invention is to provide a multi-branch wiring harness fixing structure and method for automobile seats, which is used for the safe fixing of multi-branch wiring harnesses at the connection between the seat cushion and the backrest, fundamentally overcoming the shortcomings of the prior art.

[0004] This invention provides a wiring harness covering structure for a car seat backrest cover, comprising: a backrest frame, backrest foam foamed on the backrest, a seat wiring harness passing through the backrest foam, and a backrest cover assembly covering the backrest foam. A wiring harness avoidance covering panel assembly is sewn to the bottom of the backrest cover assembly. Two symmetrically arranged wiring harness avoidance covering panel assemblies are used to consistently cover both sides of the bottom of the backrest foam. Each wiring harness avoidance covering panel assembly includes: a panel body, and a panel sewn to the panel body. The top hook strip and the hook plate sewn to the backrest cover assembly located at the bottom of the backrest side wing, the side of the cut piece body has a folded sewing edge, the top of the cut piece body has a hook connection edge, the folded sewing edge is folded and sewn and wrapped around the reserved protrusion at the bottom of the backrest foam, the hook connection edge is fixed to the hook plate at the bottom of the backrest side wing by the hook strip, so that the wire harness avoids the cut piece assembly moving with the backrest, thereby covering the bottom position of the backrest foam at different angles in real time.

[0005] As a preferred embodiment of the present invention, the material of the hook strip is PP plastic, and the end of the hook strip is provided with a hook.

[0006] As a preferred embodiment of the present invention, the material of the hanging plate is PP plastic, the hanging plate is U-shaped, and the hook of the hanging strip is hooked into the U-shaped groove of the hanging plate.

[0007] The beneficial effects of this invention are as follows:

[0008] 1. The present invention uses the wire harness avoidance and cover panel assembly to ensure that no matter what angle the seat back is adjusted to, the wire harness avoidance and cover panel assembly on both sides can firmly cover the bottom two ends of the backrest foam, preventing the risk of the internal foam parts being exposed at a certain angle due to the height difference on both sides of the foam after the wire harness is assembled.

[0009] 2. The wire harness avoidance cover piece assembly of the present invention is fixed to the hook plate on the seat cover by the hook strip, which is convenient and simple to operate, reduces the time for wire harness assembly, and also shortens the time for disassembling the wire harness when the whole chair is repaired.

[0020] See Figure 1-9As shown, this embodiment provides a car seat backrest cover wire harness covering structure, including: a backrest frame, a backrest foam 1 foamed on the backrest, a seat wire harness 2 passing through the backrest foam 1, and a backrest cover assembly 3 covering the backrest foam 2. A wire harness avoidance covering piece assembly 4 is sewn to the bottom of the backrest cover assembly 3. Two symmetrically arranged wire harness avoidance covering piece assemblies 4 are used to always cover the two sides of the bottom of the backrest foam 1. The wire harness avoidance covering piece assembly 4 includes: a piece body 5, and a piece sewn to the top of the piece body 5. The backrest panel 3 has a hook strip 6 and a hook plate 8 sewn onto the backrest panel assembly 3 at the bottom of the backrest side wing 7. The side of the fabric piece 5 has a folded sewing edge 9, and the top of the fabric piece 5 has a hook connecting edge 10. The folded sewing edge 9 is folded and sewn onto the reserved protrusion 11 at the bottom of the backrest foam 1. The hook connecting edge 10 is fixed to the hook plate 8 at the bottom of the backrest side wing 7 via the hook strip 6, allowing the thread harness to avoid obstructing the fabric piece assembly 4 as it moves with the backrest, thus providing real-time coverage of the bottom of the backrest foam 1 at different angles. The hook strip 6 is made of PP plastic, and a hook is provided at the end of the hook strip 6. The hook plate 8 is also made of PP plastic and is U-shaped. The hook of the hook strip 6 is hooked into the U-shaped groove of the hook plate 8.

[0021] Working principle: To address the risk of internal foam components being exposed at a specific angle due to the height difference on both sides of the foam after the wiring harness is assembled, the hook strip 6 of the wiring harness clearance cover panel assembly 4 is added to the hook plate 8 of the backrest side wing 7 for secure fastening. This ensures that no matter what angle the seat back is adjusted to, the wiring harness clearance cover panel assembly 4 on both sides of the bottom of the backrest foam 1 can firmly cover the foam at both ends. Furthermore, when disassembling the wiring harness later, only the hook needs to be removed.

[0022] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention 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 the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
