Abstract: In a fastening device for a tiltable steering wheel assembly, the locking lever of the device is set in the locked position beyond the rotary dead point of a rotary cam element pivoted on a fastening bolt so as to firmly hold the steering column tube assembly at a desired angle with respect to the driver. The locking lever is positioned substantially parallel with respect to the steering column tube assembly in the locked position to prevent unexpected release of the locking lever by the driver's legs.

Abstract: A capacitively coupled tablet for use with an electrically conductive pen comprises segments each including at least one lattice point of a matrix which comprises groups of spaced conductors which are disposed along coordinate axes. The segments are mutually electrically isolated by an electrically conductive shield layer having apertures which correspond to the surface area of the respective segments, and are marked with corresponding characters to serve as keys. An electrically insulating layer is disposed between the shield layer and the groups of conductors, and a similar surface layer is disposed on the shield layer.
