Passenger seats play an important role for transportation due to the comfort and safety of the occupant while traveling. The primary duty of a seat is to provide seating space for the passengers. In addition, the passenger is subjected to various forces in a crash event and, therefore, the seat must protect the occupant. Seats should also absorb vibration and noise for comfortable travelling.
Consequently, a seat design should look smart, be lightweight and meet safety requirements. The development of passenger seats in the medium term will continue to be a competition between requirements of safety, comfort, low costs, and light weighting.
Light weighting is an integrative technique that utilizes all fields of optimized design, manufacturing techniques and suitable material selection. It is a technique to reduce the mass of an entire structure and its single elements while increasing the functional quality. The EV Seats are focused more upon the light weighting considering its structure of mobilisation.

The demands placed on future electric vehicle cockpits are very considerable: Car drivers expect the same kind of seamless connectivity that they have become accustomed to when using their smartphones; the automotive industry’s safety and security standards are very stringent; and vehicle manufacturers want highly versatile systems that cost as little as possible.
Carbon emission requirements have altered the automobile market’s structure in recent years, with big SUV-type vehicles giving way to more fuel-efficient, smaller cars. With fuel economy in mind, one of the industry’s main developments is the decrease of vehicle mass with the goal of lowering emissions. When it comes to ‘light weighting,’ no component of the automobile has avoided inspection, and seating is one area that has seen a slew of innovative designs and ideas to assist decrease overall vehicle weight.
Because of the duties it must fulfil, the driver’s seat is the most complicated and, as a result, the heaviest of the seats. To provide the driver with a comfortable driving posture, the seat must be ergonomically constructed and well-shaped/cushioned.
The structure, together with seat belts and airbags, must protect the driver in the case of an accident; and the seat should also give the driver the ability to integrate for better EV mobilisation efforts. One of the biggest suppliers of seating and related components to the automotive industry, Faurecia, is developing new modular seating structures with metal alloys to achieve significant weight reductions.
The recent market trend has been made within the World Auto Steel ‘Future Steel Vehicle’ concept is a lightweight body structure concept for future electric and hybrid vehicles, which demonstrated a 35% reduction in weight compared to the project baseline vehicle, and a 23% weight reduction compared to current production small vehicles. As part of the project, Tata Steel was tasked with designing and developing the front seat structure for the Future Steel Vehicle (FSV).
The Global Electric Vehicle Seats Market can be segmented into following categories for further analysis.
There has been some recent development in terms of technological integrations at various levels in EV Seats. The Autonomous Vehicles Technology or ADAS which is being integrated on a full-fledged requirements within the EVs has been giving the approval for various levels of improved focus on the adaptivity of seat technologies.
A complete seating concept for privately owned autonomous level 3-4 vehicles is being designed in the EVs which is integrated with a collection of adaptive, modular innovations designed to serve a wide range of vehicles. Each innovation is optimized to deliver safety, comfort, convenience and provide opportunity for differentiation by brand and product segment.
Adaptive seating rotates 15 degrees inward enabling occupants while offering optimized comfort for relaxing commutes. All while minimizing environmental impact by maximizing space. The integration of intelligent front seats monitor sitting positions, measure occupants’ heart and respiration rates and can even assess their stress levels and provide solutions to address any issues.
All seating functions and other vehicle settings are controlled via a smart command panel integrated into the driver’s seat. Therefore, the seat in the automated vehicle becomes the command center wherever the driver moves in the vehicle space. The Anthropometric Pivot (ATP) guarantees that the seat reclines with the occupant’s body and offers support even when reclined beyond the conventional range, with all components coordinated to adapt for optimal comfort.
Faurecia Seating develops and produces seat systems that optimize the comfort and safety of occupants and offer premium quality to its customers. It develops innovative solutions for thermal and postural comfort, health and wellness, and advanced safety for the use cases of today and the Cockpit of the Future.
FAS’s sustainability innovation approach extends beyond OEM standards and objectives, aiming to enhance manufacturing processes, materials utilised, and seat design in order to minimise the CO2 footprint of their systems throughout their life cycle. Steel and plastics, materials used in seating, together represent almost 50% of the Group’s CO2 emissions. Seat for the Planet is thus particularly relevant to the Group’s CO2 neutrality objective.
Adient Group has made a focused approach on integrating various elements of importance into consideration for better technological implementation towards the key elements. From front and rear structures to tracks, recliners, height adjusters and locks are based on standardized designs. The cutting-edge trim technology provides our customers a substantial advantage. During the design stage, our proprietary 3D in-mould embellishment process allows clients to modify trim and save money.
