Anordnung zum kontaktlosen Übertragen von Signalen zwischen gegeneinander linear bewegbaren Fahrzeugteilen

摘要

Described is a non-contacting device for the transmission of signals between for instance at least one circuit mounted on the bodywork of a vehicle and at least one circuit in a vehicle seat mounted to slide on rails, the frictionless device ensuring interference-free signal transmission. The device consists of at least one transformer whose primary (4) and secondary (6) windings are located in separate pot cores (1, 2), one of which is attached to the fixed vehicle part (bodywork) while the other is attached to the movable vehicle part (seat). Both pot cores (1, 2) are designed as rails which can slide longitudinally which respect to each other, the cross section of the rails being such that together they form a closed circuit for the magnetic flux between the primary (4) and secondary (6) windings.
