Abstract

Lighting device indicating a configuration state of a seat of a motor vehicle, the lighting device being arranged to illuminate at least one part of the seat as a function of at least one datum relating to the configuration state of this at least one part of a seat relative to a configuration instruction for a given user.

Claims

1. Lighting device indicating a configuration state of a seat, the lighting device being arranged to illuminate at least one part of the seat as a function of at least one datum relating to the configuration state of this at least one part of a seat relative to a configuration instruction for a given user.

2. Lighting device according to claim 1, wherein the configuration state of the at least one part of the seat comprises at least one non-conforming state and one conforming state, the illumination of the seat by the lighting device differing depending on the configuration state of the at least one part of the seat.

3. Lighting device according to claim 2, wherein the configuration state comprises at least one intermediate configuration state, the intermediate configuration state being a state between the conforming state and the non-conforming state.

4. Lighting device according to claim 1, wherein the device comprises a control module configured to modify the illumination of the at least one part of the seat as a function of the identity of a user of the vehicle.

5. Lighting device according to claim 1, wherein the configuration of the seat comprises the adjustment of the seat base, of the rake of a backrest, of a headrest, the position of an armrest, adjustment of the height of a safety belt, the distance from a steering wheel, the firmness of the seat base or the backrest, and the part of the seat situated in the lumbar region of the user.

6. Lighting device according to claim 1, wherein the device comprises at least one projection means arranged in at least one part of the seat.

7. Lighting device according to claim 6, wherein the at least one part of the seat in which the at least one projection means is arranged may be:

the seat base, the backrest, the headrest, an armrest or the support of the seat base.

8. Lighting device according to claim 6, wherein the at least one part of the seat in which the at least one projection means is arranged comprises either luminous fibers which form the seat covering, or a translucent and/or transparent portion which reveals the light beams emitted by devices integrated in the structure of the seat.

9. Lighting device according to claim 1, wherein the device comprises at least one projection means arranged in at least one structural element of the cab of the vehicle.

10. Lighting device according to claim 9, wherein the at least one structural element of the cab in which the at least one projection means is arranged may be:

a roof of the cab, a roof light, a door pillar, a steering wheel or a center console.

11. Lighting device according to claim 1, wherein the passage of the seat from a non-configured state to a configured state is initiated by one of the following methods:

timed programming, anticipated actuation, detection by the weight of the user, detection by camera or fingerprint or voice, detection by identification of the key or an element of the key, automatically or deliberately by a user, detection by a mobile means, in particular a mobile telephone, a smartphone or a tablet or any other mobile communication means.

12. Assembly for configuring a seat of a motor vehicle comprising at least one lighting device according to claim 1.

13. Seat of a motor vehicle comprising at least one lighting device according to claim 6.

15. Lighting device according to claim 2, wherein the device comprises a control module configured to modify the illumination of the at least one part of the seat as a function of the identity of a user of the vehicle.

16. Lighting device according to claim 2, wherein the configuration of the seat comprises the adjustment of the seat base, of the rake of a backrest, of a headrest, the position of an armrest, adjustment of the height of a safety belt, the distance from a steering wheel, the firmness of the seat base or the backrest, and the part of the seat situated in the lumbar region of the user.

17. Lighting device according to claim 2, wherein the device comprises at least one projection means arranged in at least one part of the seat.

18. Lighting device according to claim 7, wherein the at least one part of the seat in which the at least one projection means is arranged comprises either luminous fibers which form the seat covering, or a translucent and/or transparent portion which reveals the light beams emitted by devices integrated in the structure of the seat.

19. Lighting device according to claim 2, wherein the device comprises at least one projection means arranged in at least one structural element of the cab of the vehicle.

20. Lighting device according to claim 2, wherein the passage of the seat from a non-configured state to a configured state is initiated by one of the following methods:

timed programming, anticipated actuation, detection by the weight of the user, detection by camera or fingerprint or voice, detection by identification of the key or an element of the key, automatically or deliberately by a user, detection by a mobile means, in particular a mobile telephone, a smartphone or a tablet or any other mobile communication means.

14. Method for indicating the configuration of a seat of a vehicle by illumination of all or part of the seat, during which at least one datum is acquired representative of the configuration of the seat and/or its development, and a subsequent step of configuration of the illumination of the seat as a function of this datum.
