Abstract:
PCT No. PCT/DE96/01115 Sec. 371 Date Feb. 27, 1998 Sec. 102(e) Date Feb. 27, 1998 PCT Filed Jun. 25, 1996 PCT Pub. No. WO97/09201 PCT Pub. Date Mar. 13, 1997The transfer unit which brings about the signal connection between an airbag installed in a steering wheel and a circuit arranged outside the steering wheel possesses a primary and a secondary winding which are located in separate annular dished cores which are mounted rotatably with respect to one another about the steering wheel axis. To ensure that the transfer unit transfers airbag measurement signals with minimal falsification, one of its two dished cores is equipped with a U-shaped cross section, and the other dished core projects into the latter, so that the magnetic flux intersects the air gaps remaining between the two dished cores preferably in a direction radial to the rotation axis.
