Abstract
An arrangement for contactless transmission of signals, e.g., between at least one circuit unit installed on the vehicle body and at least one circuit unit in a vehicle seat mounted displaceably on rails is described. This arrangement is free of wear and guarantees interference-free signal transmission. This arrangement consists of at least one repeating coil whose primary winding and secondary winding are in separate pot-type cores, one of which is mounted on a stationary vehicle part (body) and the other is mounted on the movable vehicle part (vehicle seat). Both pot-type cores are designed as rails sliding along one another and having sections such that together they form a closed circuit for the magnetic flux between the primary winding and the secondary winding.
