Abstract: An illumination device for a display instrument is described which is used to illuminate two sets of scale markings and to separately illuminate a pointer scale of the display instrument. The light from a light source is guided past light funnels that are used to illuminate the pointer scale by an optical waveguide. This provides an efficient and economical means of illuminating a display instrument of this type.

Abstract: A display device for a motor vehicle. In order to allow a compact, space-saving and cost-effective design and a rotation of the display with little change in position, the display device includes a display housing for mounting on a vehicle dashboard; and a display frame for accommodating a display. The display is rotatable with respect to the display housing. The display device further includes a driven element affixed on the display housing; and a drive device affixed on the display frame, having an electric motor, a worm gear and a gear-output shaft for engaging with the driven element. The electric motor arranged in a center region of the display frame and the engagement of the gear-output shaft with the driven element occurs outside the axis of rotation.

Abstract: A lighting device for lighting a display surface is provided. The lighting device includes a light source, a lighting well and a lens, which is arranged between the light source and the display surface. Due to the combined use of the lighting well and the lens, light scattered laterally is also reflected in the direction of the display surface.

Abstract: With the disclosure shaft drive device, has a PCB device (1, 1′); a rotor device (50; 5, 51) with a rotor (5) and a rotor shaft (51) attached to it; and a stator device (40) for driving the rotor (5) with the rotor shaft (51); an attachment device (60) for attaching the rotor device (50; 5, 51) and the stator device (40) to the PCB device (1, 1′) in such a way that the PCB device (5) forms part of the frame, surrounding the rotor shaft, of the shaft drive device.

Abstract: A lighting device for lighting a display surface is described. The lighting device includes a light source, a lighting well and a lens, which is situated between the light source and the display surface. This yields a homogeneous and efficient lighting of a display surface.

Abstract: A tubular-shaped housing comprising a flexible, belt-shaped wall arranged around a display instrument and/or a front pane of the display instrument. The tubular shaped housing is formed by bending the flexible, belt-shaped wall around the display instrument and/or front pane. The belt-shaped wall can be used for differently shaped display instruments and/or front panes, since the flexibility of the belt-shaped wall allows it to adapt to the outer contour of the display instrument and/or of the front pane.
