Deepal patents an extendable rear-seat foot bath with heated water, massage rollers and anti-slosh design. Here is how it works.
Nio EV features Deepal Patents Extendable Foot Bath For Rear Passengers To Soak On The Move official exterior hero view
🚀 Key Takeaways:
• Deepal, the Changan sub-brand, has filed a patent for a rear-seat foot bath.
• The basin extends from beneath the front seats and can be heated, with massage rollers.
• Anti-slosh guide holes and a disinfection assembly aim to keep the water in place.

Rolls-Royce owners sink their feet into deep lambswool carpets, but Deepal wants to go one step further. The Chinese EV brand has filed a Deepal patent for an extendable rear foot bath that slides out from under the front seats. Passengers could soak their feet while the car is moving.

Inside The Deepal Patent’s Anti-Slosh Engineering

Sloshing is the obvious problem. Anyone who has driven with a coffee cup knows how quickly liquid escapes over a bump or a sharp turn. According to Deepal, the basin’s design blocks water from splashing out, while guide holes let displaced water recirculate into the bottom. The liquid level stays low, at least on paper.

Still, the physics of a moving reservoir is unforgiving. Like the modified Dodge Charger that outgrew its own transmission, the concept depends on whether real-world forces match the engineering drawings.

Heated Soaks And Massaging Rollers

The basin reportedly uses heated water and rollers at the bottom for a light foot massage. A disinfection assembly keeps the water from turning stagnant, and a quick-disconnect drain lets owners empty the tank without leaving the cabin.

Even so, the practical questions are stacking up. Without a towel rack or cubby, wet feet mean soaked carpets, and damp carpets invite mold. That is a serious problem in a premium interior.

Will This Foot Bath Reach Production?

Probably not. Automakers patent speculative ideas to protect future options, and most never reach a showroom. Foot baths are popular in China, though, so demand is not zero. Ultimately, the Deepal patent is more a glimpse of rear-seat ambition than a product you can order.

For now, deep carpets and bare feet still do the job. Die Hard style, it is.
