Abstract: A command selector includes a scroll wheel mounted in a support and free to rotate about a main axis, a fixed printed circuit board, a detection wheel rotating about a secondary axis, a means of transmission rotationally connecting the scroll wheel to the detection wheel of which the rotations are detected by a rotation sensor arranged on the printed circuit board. The main axis and the secondary axis are non-parallel, the means of transmission defines an angle, and the detection wheel rotating in a plane parallel to the printed circuit board, the secondary axis being perpendicular to the printed circuit board, so as to minimize the circumscribed volume of the selector.

Abstract: A control module includes a fixed control apparatus which is provided with a touch-sensitive surface so as to provide a control signal representative of the position or of the movement of a finger on the sensitive surface. The sensitive surface of the control apparatus includes a toroidal portion arranged about a main axis. The control module includes a control unit which is designed to detect an axial component and a circumferential component of a tactile movement on the sensitive surface so as to produce a processed control signal which is a function of these two components.

Abstract: The invention relates to a head-up display device, including a projector for generating a light beam carrying information to be displayed, a combiner having a display position for displaying the information in the field of vision of a user, and an optical system defining an optical path between the projector and the combiner when the latter is in the display position thereof, for directing the light beam onto the combiner. The optical system includes a first and a second deflecting mirror. The first mirror is arranged for receiving the light beam from the projector and for sending said light beam to the second mirror, the latter being arranged for sending the light beam over the optical path toward the combiner. An actuation system is provided for adjusting the length of the optical path between the projector and the combiner by positioning the first and second deflecting mirrors.

Abstract: An instrument cluster, in particular for a motor vehicle comprises a display screen to display information to the driver of the vehicle, a holographic memory containing the information stored in the form of holograms, and a light source to generate one or more reading light beams to extract the information to be displayed from the holographic memory and display the information extracted from the holographic memory on the display screen. A head-up display device is integrated in the instrument cluster and comprises a combiner that projects information extracted from the holographic memory into the head-up field of view of the driver.

Abstract: An indicator device for vehicles includes a fixed support mounted in the vicinity of a steering column, an actuation lever, a moveable finger mechanically connected to the actuation lever, and safety means. In accordance with an embodiment of the invention, the moveable finger is mounted on the fixed support slidingly between a position of engagement of its free end, pivoting of the moveable finger being possible only in the engagement position. Return means are provided to return the finger into its disengaged position. The moveable finger and the fixed support each include an indexing surface, and the two surfaces are superimposed as to co-operate with an elastic push button on the end of the actuation lever.
