Embodiment Construction

[0028] figure 1 A vertical sectional view of an input device 1 for a motor vehicle is shown. The input device 1 may be part of an operator control of a motor vehicle. The input device 1 has a cover 2 . The cover 2 constitutes the exterior of the input device 1 . The cover 2 may be a housing part of the housing of the input device 1 . The cover 2 has an inlet face 3 . In an exemplary embodiment, a plurality of areas 4 and 5 that can be backlit are formed on the input face 3 . It is also possible to provide a further area 6 which can be backlit.

[0029] In particular, an operator control area 7 is also formed on the input surface 3 . In the exemplary embodiment shown, the operator control area 7 is embodied as a recess or depression in the input face 3 and thus also in the cover 2 .

[0030] The input device 1 is designed to detect activation capacitively. If, for example, a finger acts on the area 7 , this activation can be sensed by the capacitive sensor system of the...

Abstract

One aspect of the invention relates to an input device (1) for a motor vehicle, having a cover (2) which has an input surface (3) with at least one light source (15); a light guide (10) with which the light (L) the light source (15) can be guided to at least one backlit area (4, 5, 6) formed on the input surface (3); and a first printed circuit board (19) on which the light source (15) is arranged, wherein the input device (1) has, in addition to the first circuit board (19), a flexible circuit board (8) which is arranged between the light guide (10) and the first circuit board (19).

Description

technical field [0001] One aspect of the invention relates to an input device for a motor vehicle. The input device has a cover. The cover has an input face. Furthermore, the input device has at least one light source and at least one light guide. A light guide can be used to direct light from the light source to at least one area that can be backlit and formed on the input face. Furthermore, the input device has a first circuit board on which the light source is arranged. Background technique [0002] Input devices for motor vehicles having capacitive sensing systems are well known. In such a capacitive sensor, its activation is sensed capacitively, for example by touching the input surface with a finger of the user. In this case it is also known to visually indicate such local activation regions of the input surface. This is done, for example, with areas that can be backlit. As a result, the user can visually recognize on the input surface where the partial area of ...
