Seats and Interior for Toyota bZ7

For the BEV sedan “bZ7,” Toyota Boshoku has been deeply involved in the development and manufacturing of the cabin space and interior, creating seat and interior systems aligned with the vehicle’s overall concept. By incorporating a sense of refinement, advanced comfort, and a sustainability-minded approach, the company is shaping an interior environment that harmonizes with driving scenarios unique to BEVs. The "bZ7" features seats driven by dual motors, allowing occupants to experience a sensation similar to weightlessness. Nappa leather upholstery provides a fine, soft touch, while the combination of ventilation and seat heater functions supports comfortable seating throughout the year. In addition, the seatback angle can be adjusted by up to approximately 10 degrees, accommodating a wide range of seating postures and individual preferences.

Seats for Toyota Alphard

The Alphard seats are designed based on ergonomic principles to pursue a high level of ride comfort. Across all grades, the seats are equipped with both heater and ventilation functions, helping to adjust perceived comfort according to the surrounding temperature conditions. A massage function inspired by shiatsu techniques uses multiple control modes to recreate the sensation of human hands applying pressure, supporting the reduction of fatigue during long journeys. In addition, the power seats allow for a wide range of seatback angle adjustment, and when combined with the lifting and extending leg support, enable occupants to adopt a relaxed seating posture close to a reclined position. The internal cushioning employs low-resilience polyurethane foam to absorb fine vibrations during driving. The seat upholstery uses high-quality semi-aniline leather that balances breathability, softness, and durability, achieving both a refined tactile feel and sustained comfort.

Personal Headrest and Health Monitoring Seat

Toyota Boshoku works to advance the evolution of the cabin space based on its guiding principles of safety, environment, and comfort, proposing solutions that combine a human-centered approach with advanced technologies. Personal Headrest Speaker

Directional acoustic technology is built into the seat headrests, creating a “personal audio space” in which each occupant can enjoy content without concern for their surroundings. Music, video, and phone calls can be enjoyed on an individual seat basis, with sound delivered in a focused manner to the listener’s immediate area, helping to minimize interference with other passengers. While maintaining an immersive experience, this system supports a sound environment that respects personal privacy, even in future shared-mobility scenarios.

Heart Rate and Respiration

Monitoring High-sensitivity sensors are embedded within the seat structure to monitor biometric information such as heart rate and breathing conditions in real time. By detecting changes in physical condition, signs of fatigue, or indications of sudden abnormalities, the system enhances a sense of reassurance while driving and supports a more comfortable way of spending time inside the vehicle. Through these technologies, Toyota Boshoku contributes to creating an interior environment in which occupants can spend their travel time with greater peace of mind.

Multi-Linked Ambient Lighting

Against the backdrop of the cabin space expanding into a “third living space,” this concept incorporates lighting effects synchronized with the rhythm of music and visual content through AI-based audio analysis. By allowing light to naturally synchronize and shift in response to the flow of content, the system creates a rhythmical and comfortable spatial experience. This system has been developed in collaboration with YAMAHA, combining smooth surface-emitting lighting technology with control algorithms to deliver an experience in which visual and auditory elements are harmonized. The exhibit deepens the enjoyment of content and extends moments of immersion, presenting a space designed for more engaging and immersive experiences.

Mono-Material Door Trim

Approximately 30 kilograms of resin materials are used in interior components for each vehicle, many of which are difficult to collect and recycle due to their structures that combine multiple different materials. In response to this challenge, Toyota Boshoku reviewed the material composition of door trims with the goal of improving recyclability while also reducing carbon dioxide emissions. Door trims, which account for a large proportion of resin usage, have been converted from conventional composite structures to a single olefin-based material, while maintaining product performance and transitioning to a configuration that is easier to recycle. From the base material and surface layer to the foam, adhesive, and internal fibers, all components are made of olefin-based materials with similar chemical properties, making it possible to collect and recycle them more efficiently after disposal without the need for complex sorting or separation processes.

UpCycleZ Recrafted Products

Toyota Boshoku aims to create comfortable mobility spaces while also addressing social challenges through manufacturing. As one of its efforts to minimize environmental impact throughout the product manufacturing process, the company collects and regenerates seat upholstery offcuts that were previously discarded, launching the upcycling brand “UpCycleZ.” By giving new value to materials that were approaching the end of their original use, Toyota Boshoku is steadily advancing initiatives that promote the circulation of resources. Through the accumulation of small, continuous actions, these materials are carried forward and brought back into use once again.
