Abstract
The arrangement includes a transformer whose primary winding and secondary winding are in separate pot cores which can rotate in opposite directions about the axis of rotation of the steering wheel. To prevent these transformers from transferring energy to the squib which could deploy the air bag when a short-circuit to lines carrying on-board voltage occurs on its primary side, only one of the two pot cores is designed as a closed ring and the other pot core is made of one or more ring segments.
