^{In a} further embodiment of this innovation, it is also proposed that mechanical, electronic or similar impulse-controlled resolvers be used as the connection between thin switches and the on-board electrical system.

In ti- " 7 ^r in'jng an embodiment of the innovation is shown. It shows:

1 shows the: Sch? Nnatisierto plan view of a motor vehicle steering wheel and

Fig. 2 is also a schematic! - »? Sectional view to Fig. 1.

To the curvature a of the steering wheel rim 1 lie in a concentric course t a number of operating switches 2 for the most varied of signal functions; the mutual distance a to b corresponds to the length of a slightly curved thumb. Advantageous is ludem 2 3UF segments 7 h, the arrangement of these switches on both sides of the hub or the hub cushion 5. A portion of 2 ¹ of the switch 2, located in an additional segment lane b ^1, c in a different plane d to the segment level, the Switch 2 runs. This eliminates the risk of unintentional operating errors; ujis indicated by dash-dotted lines, the segments 3 can also be designed with a different curvature than a, ie also as a straight strip 3 '.

üJie. is shown in Fig. 2, are now at least according to the innovation part of the known switches 2, 2 'bzui. additional elements 2 " Individually or as segments with finger spacing "f" on the Steering rear 5 'arranged. It is therefore conceivable next to eggs usual On / Off function of each switch now also this variation option: Upper side switch 2, 2 'only "On" and assignment of internal side switches 2 "only" off, or vice versa.

As is well known, the transfer bzu. electric forwarding of the Switching pulses from the rotating part, namely the steering wheel 1, 5 to the fixed steering wheel mounts and thus to the electrical system Can cause some difficulties, and will also be new proposed in addition to mechanical transmission links in this Transfer area, electronic, or similar pulse-controlled "resolvers" Or the like to be provided.

Claims (2)

1. Motor vehicle safety steering wheel with built-in operating switches for e.g. horn, direction indicator, windshield wiper, Light, etc., in which these switches are housed in the wheel spokes and / or the hub area and their electrical Connections via suitable rotary joint arrangements between Steering wheel and steering column brought up to the on-board network and these switches on concentric and tree-spaced from the steering wheel rim S-segment-like areas on both sides of the I-hub pad are arranged marked by additional switches (2 ") or switch segments with finger spacing (f) on the steering wheel backrest (5 '). 2. Safety steering wheel according to claim 1,
characterized, that as a connection between the switches (2, 2 ', 2 ") and the on-board electrical system, mechanical, electronic or other impulse-controlled Resolvers are provided.
