PCT No. PCT/DE96/01361 Sec. 371 Date May 18, 1998 Sec. 102(e) Date May 18, 1998 PCT Filed Jul. 24, 1996 PCT Pub. No. WO97/20710 PCT Pub. Date Jun. 12, 1997An 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.
