1. A system for powering components in a seat of a vehicle comprising:
- a vehicle body;
a power transmitter supported by the vehicle body and operatively connected to a vehicle power supply, the power transmitter including a far-field transmitting antenna configured to generate an electromagnetic field;
the seat supported by the vehicle body;
a first power receiver located in the seat within the electromagnetic field and operatively connected to at least one component in the seat, the first power receiver including a first far-field receiving antenna configured to receive energy from the electromagnetic field, the first power receiver configured to generate electrical power from the energy received by the first far-field receiving antenna and deliver the electrical power to the at least one component; and
a second power receiver located in the seat within the electromagnetic field and operatively connected to at least one additional component in the seat, the second power receiver including a second far-field receiving antenna configured to receive energy from the electromagnetic field, the second power receiver configured to generate additional electrical power from the energy received by the second far-field receiving antenna and deliver the additional electrical power to the at least one additional component.

Abstract
A system for powering components in a vehicle seat enables electronic components within the vehicle seat to receive power without wires connecting the seat to a vehicle body. The system includes a power transmitter that generates an electromagnetic field, and a power receiver located within the vehicle seat and the electromagnetic field. The power receiver is configured to generate electrical power from the electromagnetic field and deliver the power to at least one component in the vehicle seat.
