Abstract

An apparatus (10) for use in a vehicle (14) comprises at least one control device (140) carried by the vehicle (14), a vehicle seat (12) and at least one electrical device (180) carried by the vehicle seat (12). A latching mechanism (60) is provided for mounting the vehicle seat (12) to the vehicle (14). A first antenna, such as a pair of coils (110, 150) transmits an electrical power signal from a power source (118) on the vehicle (14) to at least one electrical device (180) carried by the vehicle seat (12). A second antenna such as a pair of antennas (120, 160) transmits communication signals between the electrical device (180) carried by the vehicle seat (12) and the control device (140) carried by the vehicle (14).
