Abstract

A device, using which signals and energy may be transmitted without contact between an electrical device on or in the vehicle body and an electrical device on or in a vehicle seat, reliable signal and energy transmission being ensured even in the event of frequent changes of the seating configuration, without the vehicle user having to take special precautions for this purpose. The two electrical devices are each assigned a transmission module. These transmission modules form a high-frequency wireless transmission path. The transmission module on or in the vehicle body is integrated into the rail system for the vehicle seat, while the transmission module on or in the seat may be coupled into the rail system in such a way that the signal and/or energy transmission occurs via the displacement current generated in the rail system.
