US Patent 11413987 Electromagnetic seat attachment and seat power

A seat assembly, a multi-passenger vehicle, and a method for attaching seats to a floor of a vehicle that employ an electromagnetic coupling between the seats and the floor. A power supply supplies electricity to the electromagnetic coupling to secure the seats to the floor and is turned off to release the seats from the floor without tools or workers bending down below the seats to remove coupling devices. The seats can therefore be readily repositioned or rearranged to adjust the spacing between the seats. Resident induction coupling is included between the floor of the vehicle and the seats to provide wireless power to the seats.
