Massaging car seats are nothing new, being commonplace in flagship luxury sedans like the BMW 7 Series and Mercedes-Benz S-Class. Heck, you can even get massaging seats in a pickup truck these days. Of course, our backs and derrières are not the only body parts we have that require some TLC, which might explain the latest patent filing by General Motors via the United States Patent and Trademark Office for a vehicle foot massager built into the floor itself. Audi has shown a vehicle foot massager before, but that one was built into the back of the front seat.

GM's patent describes "a vehicle foot massage system for a vehicle floor includes a plurality of pneumatic elements positioned on the vehicle floor, an air pressure generating device, and a plurality of connecting lines each in communication with one of the plurality of pneumatic elements and with the air pressure generating device."

What a mouthful, right? Essentially, there are small bags that fill up with air to create a massaging effect. While the technology itself has been seen before, the placement within the floor is certainly a new concept.

The patent goes on to mention a possible display screen that occupants can use to control the foot massager. In theory, the only person who definitely wouldn't have access to the feature is the driver himself. If this foot massager makes it into a production vehicle, it would only really make sense in a large luxury model where the likelihood of being chauffeured around is high.

From within the GM stable, it could be used in the new Cadillac Escalade or Escalade ESV, for instance, or perhaps in a GMC Hummer EV ferrying tired hip-hop artists home. The bigger question is whether there'd be demand for an odd upgrade that requires you to remove your shoes in the first place. We're not so sure.
