Description

Technical Field

[0001] This utility model belongs to the field of automotive seat design technology, specifically relating to an automotive seat, and more particularly to a personalized custom automotive seat. Background Technology

[0002] Over time, traditional mass production of automobiles has become unable to meet the personalized needs of every consumer. With the rapid development of my country's economy and the increase in residents' income levels, the demand for customized modifications of commercial vehicles, luxury cars, special-purpose vehicles, and new energy vehicles has rapidly increased.

[0003] Customized and modified vehicles cater to the characteristics of today's young users who value independence, seek uniqueness, and have a greater curiosity and exploratory spirit towards new things. A younger user base is becoming one of the new trends in the automotive customization and modification industry.

[0004] In recent years, domestic automakers have actively adapted to the younger generation's consumer base, launching various personalized and customized models to meet consumer demand. Many automotive-related companies have also begun to venture into the optional extras market. Currently, the biggest limitation to car modification in China is the legal and regulatory framework. At the same time, ordinary people's lack of modification knowledge easily leads to illegal modifications. In response to these issues, automakers have been continuously launching legally customized modification products to meet the needs of car modification enthusiasts.

[0005] Current car seat designs typically involve initial input from the client, followed by development of the component structures to complete the seat design. The drawback is that the frame is determined first, and other structures are designed from the outside in, constrained by the overall shape. During the design process, the arrangement and influence of various mechanisms are interdependent, requiring analysis of numerous and broad issues. Sometimes, limitations imposed by these issues can lead to the rejection of all previous designs.

[0006] For the reasons mentioned above, car seats designed and manufactured under the existing design methods cannot meet the personalized needs of customers. Summary of the Invention
