Abstract
The invention relates to a device for the wireless transmission of data and energy between an element to be mounted on or in a vehicle body, especially a vehicle sliding door (2), a vehicle seat or a comparable additional unit, and a vehicle body (1). The basic design of the inventive device comprises an electric power source (18), control electronics (17, 17′) mounted in the vehicle body and at least one pertaining coil (20) also mounted in the vehicle body. The device further comprises control electronics (11) mounted in the element and at least one pertaining coil (19) also mounted in the element. Both coils (19, 20) are inductively coupled via a common transmitting/receiving path to transmit data and energy. According to the invention, the coil (19) mounted in the element is enclosed by the coil (20) mounted in the vehicle body and can be displaced in a longitudinal direction within the coil (20) mounted in the vehicle body or vice versa.
