Embodiment Construction

[0006] According to an embodiment of the present invention, in the surface treatment method of the headrest inserting rod, the surface of the headrest inserting rod is treated by using Physical Vapor Deposition (PVD, Physical Vapor Deposition). In the case of using this method, it is more environmentally friendly and the cost is lower under the premise of meeting the plugging durability, corrosion resistance and related strength requirements of the inserting rod of the seat headrest.

[0007] According to an embodiment of the present invention, the surface treatment method of the headrest inserting rod includes the following method steps: pre-inspection, pre-treatment, physical vapor deposition treatment and final inspection.

[0008] According to an embodiment of the present invention, the pretreatment includes: decontaminating the headrest inserts to clean the surface, and roughening the headrest inserts to produce a rough surface.

[0009] According to an embodiment of the ...

Abstract

The invention discloses a surface treatment method for a headrest insertion rod. Physical vapor-phase deposition is used to treat the surface of the headrest insertion rod. On the premise of meeting insertion and extraction durability, corrosion resistance and related strength requirements of a seat headrest insertion rod, the surface treatment method is more environmentally friendly, and is lowerin cost.

Description

technical field [0001] The invention relates to the field of car seats, in particular to a surface treatment method for a headrest insert rod. Background technique [0002] The headrest rod is part of the seating system, and the split headrest is mounted on the upper part of the backrest via its inner headrest rod. In the current market, most of the headrest rods use galvanized, electrophoresis or chrome-plated surface treatment. Galvanized is corrosion-resistant and has a better surface, but it is not wear-resistant; electrophoresis is low in cost, but it is not wear-resistant and slightly anti-corrosion. It is precisely because of the poor hardness of the surface of galvanized and electrophoresis that the surface is easily scratched after a certain number of uses, resulting in a poor surface. At the same time, it is also very easy to rust after scratching. Therefore, chrome plating is currently the mainstream direction of the market, accounting for more than 95% of the ma...
