After that, when the occupant touches the protrusion 41 on the rear side, the touch is detected by the capacitance sensor 54 of the return switch 23 (return switch 23 is on). When the changeover control device 24 receives the signal corresponding to the touch from the capacitance sensor 54 of the return switch 23, the changeover control device 24 drives the vibration motor 53 of the return switch 23. By driving the vibration motor 53, vibration is transmitted to the occupant, giving the occupant a pseudo-click feeling. When the capacitance sensor 54 detects that the occupant's hand is separated from the rear protrusion 41, the changeover control device 24 turns off the light emitting element 50 of the return switch 23. The switching control device 24 further sends a signal to the motor control device 17 to drive the electric motor 11 to displace the vehicle seat 1 to the standard position.

When the displacement is completed, the switching control device 24 turns on the light emitting element 50 of the relax switch 22. By lighting the light emitting element 50 of the relax switch 22, the symbol 60 corresponding to the vehicle seat 1 in the relaxed position is displayed on the protrusion 40 on the front side. At this time, even if the occupant touches the protrusion 41 on the rear side, the switching control device 24 is configured not to react.

When the occupant leaves the seat, the seating sensor 20 is turned off. At this time, the changeover control device 24 turns off both the light emitting element 50 of the relax switch 22 and the light emitting element 50 of the return switch 23 (FIG. 3). As described above, when the occupant is not seated on the vehicle seat 1, the two light emitting elements 50 are turned off, so that energy consumption can be suppressed. When the seating sensor 20 is off, the switching control device 24 is configured so that it does not respond even if there is a touch on the front protrusion 40 and the rear protrusion 41 (both the relax switch 22 and the return switch 23 are off). Has been done.

Next, the effect of the switching device 16 will be described. When the vehicle seat 1 is in the standard position and the occupant is seated, only the front protrusion 40 is lit, and the protrusion 40 displays the symbol 60 corresponding to the vehicle seat 1 in the relaxed position. .. When the vehicle seat 1 is in the relaxed position and the occupant is seated, only the rear protrusion 41 is lit, and the protrusion 41 displays the symbol 61 corresponding to the vehicle seat 1 in the standard position. There is. Therefore, the switch to be operated by the occupant and the position thereof can be easily recognized, and the shape of the vehicle seat 1 after the operation and the function of each switch can be easily understood.

The switches 22 and 23 are preferably in a position where they can be operated by the occupant by moving the forearm in front of the fuselage. When the vehicle seat 1 is in the relaxed position, the backrest surface 10 is tilted backward and the upper body of the occupant is facing forward and upward as compared with the case where the vehicle seat 1 is in the standard position. Further, as shown in FIGS. 1 and 2, the position of the occupant's hand with the forearm moved in front of the torso is higher when the occupant's upper body is facing forward than when the occupant's upper body is facing forward. It is above. The return switch 23, which is operated when the upper body of the occupant is facing forward and upward, is located behind and above the relaxing switch 22 which is operated when the upper body is facing forward. Therefore, the return switch 23 is easier to operate than when it is located behind or below the relax switch 22.

Since the decorative member 25 is formed of a member that transmits the light emitted from the light emitting element 50, the occupant can visually recognize the light emitted from the inside of the vehicle. Further, by using the capacitance sensor 54, it is possible to detect the touch operation of the occupant on the decorative member 25 without exposing the sensor to the decorative member 25. In this way, since both the switches 22 and 23 are covered from the inside of the vehicle by the decorative member 25, the design of the door 4 is enhanced. Further, since the protrusions 40 and 41 are provided on the outside of the vehicle, the occupant can easily understand the positions of the switches 22 and 23.

The light emitted from the light emitting element 50 enters the vehicle interior 2 from the vehicle outer wall surface of the decorative member 25 facing the opening of the main body 65. Therefore, on the inner wall surface of the decorative member 25, the region located inside the opening of the main body 65 emits light. By forming the main body 65 into a tubular shape, only the portion facing the opening of the main body 65 can emit light, and the light emitting region and the non-light emitting region can be clearly separated. Further, since the light emitting element 50 and the vehicle outer wall surface of the decorative member 25 are separated from each other, the intensity of the light in the region irradiated with the light of the light emitting element 50 can be made more uniform. Further, since the light from the light emitting element 50 is scattered by the diffuser 80, the intensity of the light reaching the region located inside the vehicle inside the opening of the main body 65 is uniform on the vehicle inner wall surface of the decorative member 25. Can be. Therefore, on the vehicle inner wall surface of the decorative member 25, the region located inside the vehicle of the opening of the main body 65 can be made to emit light evenly.

Since the capacitance sensor 54 is coupled to the vehicle outer wall surface of the light emitting region of the decorative member 25, the touch on the light emitting region of the occupant can be easily detected by the capacitance sensor 54. Further, since the light-shielding member 52 is arranged along the vehicle outer wall surface of the decorative member 25, the diffraction of light is suppressed as compared with the case where the light-shielding member 52 is arranged away from the vehicle outer wall surface. The symbols 60 and 61 of the light-shielding member 52 can be displayed more clearly on the inner wall surface. Further, by providing the vibration motor 53 on the support portion 66, the vibration motor 53 can be brought close to the protrusions 40 and 41, and the vibration can be more effectively transmitted to the occupant's hand.

Although the description of the specific embodiment is completed above, the present invention can be widely modified without being limited to the above embodiment. In the present embodiment, the present invention has been applied to the switching device 16 for switching the position of the vehicle seat 1 in the right front seat, but it may be applied to the switching device for the vehicle seat in the rear seat.

May be provided in the center pillar garnish between the front door and the rear door.

In the above embodiment, both the switches 22 and 23 are configured by the capacitance sensor 54 that detects the touch of the decorative member 25 by the occupant, but the present invention is not limited to this embodiment, and for example, the decorative member 25 It may be a membrane switch or a push type switch provided in.

In the above embodiment, the protrusions 40 and 41 and the plate 39 are integrally molded, but after the protrusions 40 and 41 are molded separately from the plate 39, the protrusions 40 and 41 are formed into a plate. It may be formed by being attached to the portion 39. However, since the protrusions 40, 41 and the plate 39 are integrally formed, the connection between the protrusions 40, 41 and the plate 39 is strengthened, and the protrusions 40, 41 and the plate 39 are separated. Can be prevented.

In the above embodiment, the film 37 is formed of a resin having a transparent colored material layer, but any mode may be used as long as it transmits light from the light emitting element 50, and wood grain or the like may be printed on the surface. Further, although the identification portion 42 is thinner than the other portions, it may be thicker than the other portions. In this case, the film 37 is formed using a resin that shrinks due to heat, the film 37 and the base material 36 are adhered to each other, and then a heater is installed parallel to the surface of the base material 36 to heat the film 37. It is preferable to shrink the surface on which the heat of the film 37 is easily transferred, that is, the portion of the film 37 facing the heater. The portion of the plate portion 39 in contact with the protruding end surface and the outer surface of the vehicle contracts due to heating. On the other hand, since the side surfaces of the protrusions 40 and 41 are hard to transfer heat and shrink easily, the portion of the film 37 bonded to the side surfaces of the protrusions 40 and 41 is thicker than the other portions. Thereby, the identification portion 42 thicker than the other portions can be formed on the ridge line portion 43 and the outer edge 44.

In the above embodiment, the light emitting element 50 of the relax switch 22 is configured to always light up when the vehicle seat 1 is in the standard position, but it takes a predetermined time after the vehicle seat 1 is in the standard position. It may be configured to turn off after a lapse of time and turn on again when a touch is detected by the capacitance sensor 54.
