GM Obtains Patent for Compressed Air Foot Massage SystemMarch 1, 2021
Air ducts were installed at the passengers’ feet for foot massage.
The United States Patent and Trademark Office (USPTO) has filed a patent application for a pneumatic foot massage system for vehicle occupants.
The massage function built into the seats is very often found in premium cars today, but the engineers of the General Motors concern, apparently, decided to go even further and came up with a system for massaging the feet of passengers. The patent application reports a rather complex pneumatic structure that massages the legs using an advanced system of air ducts in the car floor and attached compressed air cylinders. All passengers can receive the massage, but the driver, for obvious reason, will not receive it.
Naturally, passengers will need to take off their shoes to use the pneumatic foot massage system. Note that the patent does not mention the heating of the air entering the legs, so the convenience of using this system remains questionable. The complexity of the design can hardly be called justified – the use of a mechanical system would be more optimal and reliable. However, there is no information about the prospects for the serial use of pneumatic massage.
