Changan Sub-Brand Deepal Files Patent for Rear-Seat Foot Bath
The proposed system features extendable basins with massage rollers and a mechanism to prevent water sloshing during transit.
Changan sub-brand Deepal has filed a patent for an extendable foot bath system designed to allow rear-seat passengers to wash their feet while the vehicle is in motion.
What Happened
According to reports from Which Car? and Car Expert, the patent describes a basin that extends from beneath the front seats, providing a space for passengers to place their feet in water. The system reportedly includes massage rollers at the bottom of the basin and a disinfection assembly to maintain water hygiene. To address stability concerns, the patent claims the basin is designed to block water from sloshing out during turns or bumps, utilizing guide holes to recirculate any displaced liquid back into the bottom of the unit. A quick disconnect feature is also included for water disposal.
Why It Matters
This filing highlights the trend among Chinese EV manufacturers to differentiate products through novel in-cabin comfort features, potentially catering to the cultural popularity of foot baths in China. While automakers frequently patent concepts that do not reach production, such innovations signal where manufacturers are directing research and development efforts regarding passenger experience. If implemented, the technology would offer a distinct luxury feature compared to traditional premium interiors, such as the lambswool carpets found in Rolls-Royce vehicles, though it introduces new challenges regarding interior moisture and mold management.
The Bottom Line
Deepal’s foot bath patent remains a concept at this stage, with no confirmation that the technology will be integrated into a production vehicle. The filing serves as an indicator of the brand's focus on unique rear-seat amenities, but practical implementation and consumer adoption remain uncertain.
