These lamps E4, E5 and E8 constitute a light emitting part of the pillar concentrated illumination part 50, and all of them are arranged below the belt line Lb. The pillar concentrated illumination unit 50 is turned on mainly when a passenger performs a boarding / exiting operation at night.

  The pillar trim 51 is formed such that a portion corresponding to the pillar concentrated illumination portion 50 is slightly bulged toward the vehicle interior side, and slit portions 53 and 54 having a predetermined width are provided above and below the bulged portion 52. The intermediate pillar lamp E4 is disposed approximately in the vertical direction between the upper and lower slit portions 53 and 54, and irradiates the upper region S4 'and the lower region S4 of the pillar trim 51 through the slits 53 and 54.

Above the bulging portion 52, an assist grip 57 that is gripped when the passenger gets on and off is provided, and the irradiation direction of the illumination light passing through the upper slit 53 is set so as to be directed to the assist grip 57. Preferably, the illumination light also illuminates the seat belt anchor 58 for the front seat 11 and the seat belt tongue 59 in the stored state.
Although the illumination light passing through the upper slit 53 is directed upward from the belt line Lb, it illuminates the upper region S4 ′ along the pillar trim 51, and illuminates the upper body of the occupant. Absent.

  The upper slit 53 corresponds to “a third irradiating portion (the irradiation direction is set so as to face the assist grip)” described in the claims of the present application, and the intermediate pillar lamp E4 corresponds to the light emitting portion. Yes. By providing such an irradiating part, visibility of the assist grip 57 at the time of getting on and off at night, more preferably visibility of the seat belt anchor 58 for the front seat 11 and the seat belt tongue 59 in the stored state, And the visibility of the vehicle interior surface of the upper part of the intermediate pillar 6 (that is, the pillar trim 51) can be improved, and the passenger can get on and off easily and smoothly.

On the other hand, the illumination light passing through the lower slit 54 irradiates the lower region S4 of the pillar trim 51, and extends in the vertical direction along the entrance / exit Hs and forms part of the outline of the entrance / exit Hs. That is, it is possible to illuminate the interior surface of the lower part of the pillar trim 51 to enhance the visibility, and to make the passenger getting on and off easily and smoothly.
The lower slit 54 corresponds to the “fourth irradiating portion (the irradiating direction is set so as to be directed to the vehicle interior surface below the pillar portion)” described in the claims of the present application, and the intermediate pillar lamp E4 is It corresponds to the light emitting part.

  In addition, a lower opening 55 having a predetermined diameter is formed at a relatively lower rear side of the bulging portion 52, and the seat downlight lamp E5 is obliquely above and below the lower opening 55 in the trim space. Has been placed. Illumination light from the seat downlight lamp E5 is irradiated obliquely downward and downward through the lower opening 55, and is set so as to be directed to the seating surface region S5 of the seat cushion 12c of the second seat 12. By illuminating the seating area S5 in this way, the occupant can easily see the seat position.

  The lower opening 55 is described in the claims of the present application. “(The irradiation direction is restricted so as to be directed to a region in the passenger compartment below the belt line, and in particular, the irradiation direction is directed to the seating surface of the seat cushion). It corresponds to the “first irradiating part”, and the sheet downlight lamp E5 corresponds to the light emitting part. By providing such an irradiating portion, the visibility of the seating surface of the seat cushion 12c of the second seat 12 when getting on and off at night can be improved, and the seating operation of the occupant can be made easy and smooth.

Further, an upper opening 56 having a predetermined diameter is formed on the relatively upper rear side of the bulging portion 52, and the inner handle lamp E8 is disposed on the side of the upper opening 56 in the trim space. Yes. Illumination light from the inner handle lamp E8 is irradiated through the upper opening 56 toward the rear substantially horizontal direction.
Immediately after the bulging portion 52 of the pillar trim 51, an inner handle 25 provided at the front portion of the slide door 20 to open and close the slide door 20 from the vehicle interior side is located. The irradiation direction of the illumination light is set so as to be directed to the inner handle 25.

  The upper opening 56 corresponds to “a second irradiating portion (the irradiation direction is set so as to face the inner handle)” described in the claims of the present application, and the inner handle lamp E8 corresponds to the light emitting portion. Yes. By providing such an irradiation unit, when the sliding door 20 is closed at the time of getting on and off at night, the inner handle 25 of the sliding door 20 and the area S8 in the vicinity thereof can be illuminated. The position can be easily visually confirmed, and convenience when getting off the vehicle is enhanced.

  The irradiation direction of the illumination light from the lower slit 54, the lower opening 55, and the upper opening 56 is limited so as to be directed to the area in the vehicle compartment below the belt line Lb. Therefore, the upper body of the passenger getting on and off is not illuminated by these illumination lights, and the passenger's privacy can be effectively protected. In other words, it is possible to achieve both improvement in night boarding / exiting performance and passenger privacy protection.

  Further, the intermediate pillar lamp E4, the seat downlight lamp E5, and the inner handle lamp E8 constituting the light emitting part of the pillar concentrated illumination part 50 are all disposed below the belt line Lb. In addition, the illumination light passing from the light emitting portions E4, E5, E8 through the lower slit 54, the lower opening 55, and the upper opening 56 is directed horizontally or downward. Thereby, it can be ensured more easily and reliably that the illumination light from the lower slit 54, the lower opening 55, and the upper opening 56 does not illuminate the upper body of the occupant.

  As described above, all of the light emitting portions E4, E5, and E8 of the pillar concentrated illumination portion 50 are accommodated in the space between the intermediate pillar 6 and the pillar trim 51 that covers the vehicle interior side. More specifically, as described above, the pillar trim 51 is formed such that the portion corresponding to the pillar concentrated illumination portion 50 slightly bulges toward the vehicle interior side, and between the bulging portion 52 and the intermediate pillar 6. The light emitting portions E4, E5, E8 are accommodated in the space portion. Therefore, without using a new member, the pillar concentrated illumination unit 50 can be provided compactly with good appearance by using a member (pillar trim 51) that is normally disposed on the vehicle interior side of the intermediate pillar 6.

In the bulging portion 52 of the pillar trim 51, the upper slit 53, the lower slit 54, the lower opening 55, and the upper portion are used as a light passing portion that allows light from the light emitting portions E 4, E 5, and E 8 to pass therethrough. An opening 56 is formed. Portions other than the light passage portions 53, 54, 55, and 56 of the bulging portion 52 constitute a light shielding portion that blocks light. This light shielding part reliably covers the upper direction of the entrance / exit Hs of the light emitting parts E4, E5, E8 and the upper direction of the second seat 12.
Accordingly, the light from the light emitting portions E4, E5, E8 is irradiated into the vehicle interior from the light passage portions 53, 54, 55, 56 provided in the bulging portion 52 of the pillar trim 51, and the second direction and the second direction of the entrance / exit Hs. The upper direction of the seat 12 is shielded by the light shielding portion of the bulging portion 52 and is not irradiated. Therefore, the upper body of the occupant is illuminated by illumination from the light emitting portions E4, E5, E8 when getting on and off. There is no.

FIG. 9 is an enlarged perspective view showing a main part of a modified example of the pillar concentrated illumination part, similarly to FIG.
In this modification, only one light source E4 ′ is disposed in the trim space, and illumination light is irradiated from the light source E4 ′ through the upper and lower slits 53, 54 and the upper and lower openings 56, 55. The positional relationship between the upper and lower slits 53 and 54 and the upper and lower openings 56 and 55 and the light source E4 ′ is suitably set according to the respective required irradiation directions. In this case, efficient illumination can be performed with one light source E4 ′. Moreover, the structure of the pillar concentration illumination part 50 'can be simplified. As the light source E4 ′, for example, a light source E4 for an intermediate pillar lamp may be used as it is.

The upper and lower slits 53 and 54 and the upper and lower openings 56 and 55 may be covered with a transparent body or semi-transparent body such as glass. In this case, entry of dust or the like into the trim space can be prevented, and the internal light sources E4, E5, E8, E4 ′ can be effectively protected.
Further, the above-described pillar concentrated illumination portions 50 and 50 ′ are not only the intermediate pillar 6 but also the rear pillar 9 (so-called C pillar: FIG. 2 and FIG. 10) extending in the vertical direction substantially along the rear edge of the entrance / exit Hs.
