Company patents
DAS CO., LTD
DAS CO., LTD's patent strategy is overwhelmingly concentrated in Vehicle Seats & Accommodations, representing 96.8% of its 93-patent portfolio, with a surprising -48.1% decline in patenting activity so far in 2026 after two years of steady growth. Despite its core focus, the company shows minor, yet inconsistent, exploration into Electric Motors & Generators and Motor Control, each accounting for only 3.2% of its portfolio, suggesting a cautious and perhaps experimental approach to diversifying beyond its primary automotive seating domain.

Seat designs and mechanisms that allow for dynamic adjustment, folding, removal, or repositioning of seats or seat components to adapt to various passenger, cargo, or vehicle usage scenarios.
Methods, tools, and component designs that facilitate the efficient and robust manufacturing, assembly, and attachment of vehicle seat structures, covers, and internal mechanisms.
Technologies specifically designed for securing children in vehicles, including child safety seats, impact absorption features, and mechanisms to ensure correct installation or detect misuse.
Safety features built into or around vehicle seats to protect occupants during various accident scenarios, including airbags, pre-crash positioning, and blast attenuation.
Non-core functionalities or convenience items directly integrated into or associated with vehicle seats, such as adjustable pillows, fitness devices, audio systems, or tray tables.
Actuators, control, and components for converting electrical energy into braking force, often involving motors, spindles, and friction elements, particularly for vehicle applications.
Integrated systems within vehicle seats that provide heating, cooling, ventilation, or air treatment (e.g., scenting) to enhance occupant comfort and well-being.
Sophisticated software or hardware-implemented control strategies that optimize motor performance, such as precise speed/torque regulation, vibration reduction, or efficiency, often using model-based, predictive, or adaptive techniques.
Techniques for determining the rotor position, speed, or other operational parameters of an electric motor without dedicated physical sensors, often relying on back-EMF, current, or voltage measurements.
