Automotive seat is the interior component that occupants contact for the longest time during the ride. Since the world’s first automobile came into being in 1885, automotive seat has evolved for over a century from a simple component into a practical tool offering comfort and safety. Global automotive seating market is dominated by American, European and Japanese brands. In 2019, North American, Japanese and European seat manufacturers commanded around 50%, 14% and 11% of the global market, separately. China’s automotive seating market is grabbed by foreign companies such as Adient and Lear and their affiliates and Toyota Boshoku, or foreign-funded joint ventures, which together sweep more than 60%.
Under the development trend of CASE, the tide of software-defined cars is unstoppable. However, software cannot define everything about vehicles. Traditional auto parts manufacturers still have many core technologies, which cannot be replaced by emerging auto-making forces, such as automotive settings. Seat manufacturers have also made a lot of intelligent improvements to seats according to the development needs of intelligent connected vehicles. Here summarized some development trends for automotive seating industry amid CASE boom.
Multi-scenario Application
In future, autonomous vehicle cockpit will be a mobile space for office, living and entertainment, so seat needs to transform for different application scenarios. An example is the next-generation reconfigurable seating concept Magna showcased at CES 2019. Users can reconfigure seats via their smartphone APP, with reconfigurable modes including vehicle sharing, long journey, and autonomous shared mobility.
Integration with ADAS
In future, automotive seat that plays a crucial role in vehicle safety will integrate with ADAS to deliver more driving assistance capabilities. Examples include InfoSeat, an automotive seating system TACHI-S and Clarion co-developed and launched in 2019: when the vehicle travels too close to the front vehicle or the driver is drowsy, the vibration device installed in the seat will send a vibrative warning to occupants.
Intelligent Control
At present, CASE is reshaping the automotive industry. Facing the disruption in automotive industry, seat manufacturers race to double down on intelligence deployment by way of such as cooperation and independent development. Future intelligent seats can not only provide comfortable experience but learn to “know” what passengers want with AI technology and adjust and control themselves without any active operation. For instance, the fusion of sensors and seats makes seat control mode change from conventional button to intelligent control methods, e.g., APP, gesture control and intention perception.
Intelligent Monitoring
In future, automotive seat will also act as a “health manager” that can monitor heart and breath rates. Examples include HiRain Technologies’ intelligent automotive seating system with the ability to intelligently monitor health, heart and breath rates, and temperature.
Personalization
As well as function intelligence, personalized design holds a trend for automotive seat, helping users to create a more private interior space. In the case of gender-targeted design, ambient lamps are used to build exclusive private sound areas.
Modularization
Automotive modular platform that helps automakers reduce cost, development time, vehicle weight and fuel consumption will be well-welcomed. For example, Brose’s complete seat modular structure allows for higher uniformity of motors in size for quick response to different customers’ needs for—any drive for basic capabilities such as adjusting length, height, seat tilt and backrest tilt, serving as an efficient supplement in comfort and safety.
Application of Intelligent Surface
As intelligent cockpit booms, decorative, functional intelligent automotive surface attracts ever more attention from industry players. Examples include BWM Vision iNext, a concept car fully demonstrating which direction intelligent automotive surface will head in. iNext allows users to operate the infotainment system by interacting with and tracking symbols on seat or side panel woven fabrics with their fingers, which replaces traditional buttons and touch screen control capability.
Replacement Cover Seat
The growing awareness of hygiene and disinfection in car comes with popularity of car sharing and current pandemic. The emergence of replacement cover seat will be an efficient way to reduce the spread of viruses and bacteria and better protect the health of occupants.
An example is the replacement cover seat co-developed by TACHI-S and SEIREN Co., Ltd. Users can replace seat covers as they like in any time. For car sharing, corporate LOGO or QR code can be printed on the cover of the seat in support of offering commercial services from information spreading and price planning to pre-order and online settlement.
Lightweight
Seats make up 6% of vehicle curb weight, and 5% of total vehicle cost, the second highest share among all components. Lightweight seats are an effective solution to vehicle energy conservation and emission reduction. Reducing the weight of seats lies in use of lightweight seat frames or complete seats.
Zero Gravity
Statistics shows that in autopilot mode, the comfortable recumbent mode (zero gravity) gives users the greatest pleasure. A zero gravity seat is a boon for them to feel less tired during the journey. For example, in June 2020 Yanfeng Automotive Interiors introduced XiM21, a self-developed intelligent cockpit featuring a zero gravity seat that affords a large angle tilt, integrates with massage function and lets passengers relax their body and mind with fragrance from the hidden air outlet.
