Safety arrangement for use in a motor vehicle
First Claim
1. A safety arrangement for use in a motor vehicle, the safety arrangement comprising rail means including a rail provided on the floor of the vehicle and a vehicle seat movably mounted on the rail means, the rail being associated with a plurality of primary coils at positions spaced along a length of the rail, said primary coils acting as transmitting antennas and the seat being associated with at least one receiving antenna, the at least one receiving antenna being in the form of at least one secondary electromagnetic coil, the arrangement further comprising means to supply a signal to at least one of the transmitting antennas to transfer power to the at least one receiving antenna, there being a safety device which is one of mounted in and mounted on the seat, actuating means being provided to use the power transferred to the at least one receiving antenna to actuate the safety device, the arrangement incorporating selector means adapted to select at least one of the primary coils which receives power to be transferred to the at least one secondary coil, there being a seat position sensor adapted to sense the position of the seat mounted on the rail, and to control the selector means in dependence upon the sensed position of the seat to supply the power to at least one of the primary coils adjacent the seat.
