DETAILED DESCRIPTION OF THE DRAWINGS

(6) FIGS. 1A and 1B show an exemplary embodiment of a textile material 10 with conductive elements.

(7) The textile material 10 comprises a textile substrate 12 formed in two dimensions with a first surface 14 and with a second surface 16. The first surface 14 is shown in FIG. 1A, whereas the second surface 16 is shown in FIG. 1B.

(8) As shown in FIG. 1A, in this exemplary embodiment a conductor track 20 and a sensitive element 30 have been printed onto the first surface 14 with a conductive paint. The conductor track 20 and the sensitive element 30 have been imprinted so as to be connected to one another in conducting manner. The sensitive element 30 has preferably been imprinted two-dimensionally, particularly preferably in a triangular shape or in the shape of a V. In addition to the conductor track 20 and the sensitive element 30, at least one further conductor track 20.1 may have been imprinted onto the first surface 14. As a result, a capacitive switch can be provided.

(9) As shown in FIG. 1B, the textile substrate 12 has been cut around a partial periphery of the sensitive element 30. For instance, the textile substrate 12 may have been cut around the two triangle sides of the sensitive element 30 that are located opposite the conductor track 20.

(10) In order that the sensitive element 30 has finally been arranged on the second surface 16, a folding region 18a, resulting from the cut, with the sensitive element 30 has been folded along a folding edge 18b of the textile substrate in such a way that the second surface 16 of the folding region 18a points toward the unfolded second surface 16. Hence a through-contacting onto the second surface 16 is obtained.

(11) FIG. 2 shows another exemplary embodiment of the textile material 10 with conductive elements. In this sectional view, the textile substrate 12 with the first surface 14 and with the second surface 16 is likewise shown. Similar to FIG. 1A, the conductor track 20 has been printed onto the first surface 14 with a conductive paint. At least one further conductor track 20.1 may also have been imprinted (not shown) onto the first surface 14. Consequently a capacitive switch can again be provided.

(12) In FIG. 2 it is evident that a conductive thread 40 on the second surface 16 has been sewn through the textile substrate 12 and on a region of the conductor track 20 on the first surface 14. By virtue of the fact that the conductive thread 40 has been sewn on the region of the conductor track 20, the conductive thread 40 has been connected to the conductor track 20 in electrically conducting manner. On the second surface 16 the conductive thread 40 consequently forms the sensitive element 30, and the textile substrate 12 has consequently been selectively perforated in the region of the sensitive element 30. Hence a through-contacting onto the second surface 16 is obtained. The conductive thread 40 has preferentially been stitched two-dimensionally on the second surface 16.

(13) FIGS. 3A and 3B show a printing of the textile substrate 12 on its first surface 14 according to FIGS. 1A, 1B and 2. For the purpose of simplification, only conductor tracks 20 are shown in FIGS. 3A and 3B.

(14) FIGS. 3C and 3D show an exemplary arrangement of the textile material on an armrest 50 in the passenger compartment of the vehicle. The first surface 14 is being mounted on the armrest 50. The second surface 16 and the sensitive element 30 consequently point into the passenger compartment of the vehicle. The conductor track(s) 20 has/have thereby been protected against unintentional touching.

(15) In all embodiments, the textile material 10 with the textile substrate 12, with the conductor track 20 and with the sensitive element 30 (imprinted as in FIGS. 1A and 1B, or sewn on as in FIG. 2) may have been designed to be stretchable.
