Description

Technical Field

[0001] The invention relates to the technical field of automobile seats, and in particular to a middle armrest assembly of a rear seat and a manufacturing method thereof. Background Art

[0002] The center armrest of the rear seat is a key element in the design of the car interior, especially in vehicles with multiple passengers. It not only provides passengers with additional support and comfort, but also enhances the sense of security when riding in the car. For long-distance travel or family outings, the center armrest of the rear seat can effectively prevent passengers from shaking due to the bumps of the vehicle, ensuring a smoother journey. In addition, it can also serve as a small platform for placing items, such as water cups, handbags or water bottles, greatly improving the practicality of the car. Especially in family cars that need to take care of children, the presence of the center armrest of the rear seat makes it convenient for parents to reach their children at any time and provide necessary help. Therefore, a well-designed and fully functional center armrest of the rear seat can not only enhance the passenger's riding experience, but also ensure safety at critical moments, and is an indispensable part of modern cars.

[0003] At present, when a middle armrest is provided in the rear seat of a car, a reversible and storable armrest structure is mainly used in the middle of the rear seat, which can be combined with the rear seat backrest in the storable state to form a complete and coherent backrest structure so that multiple people can sit on the backrest. In addition, when there is no passenger in the middle, the armrest can be turned down for support. Although this middle armrest is easy to flip and store, it still has the following problems:

[0004] 1. When the passenger in the middle armrest position uses the armrest as a backrest, there is a lack of lumbar support. Especially in the middle footrest position of the rear seat, there is a protruding platform structure, and the lack of lumbar support makes the middle passenger feel strenuous when riding, thus reducing comfort;

[0005] 2. When the armrest is turned out, there is usually a groove on the armrest to place the teacup. However, braking and acceleration may occur during driving, making it difficult to place the teacup stably on the armrest.

[0006] In summary, there is a need for a rear seat center armrest assembly that has a comfortable backrest and is easy to use. Summary of the invention
