  Hereinafter, the form for implementing this invention is demonstrated using FIGS. In the following description, the terms “up”, “down”, “front”, “rear”, “left”, and “right” refer to the directions of “up”, “down”, “front”, “rear”, “left”, “right”, The direction of up, down, front, back, left and right is shown.

  First, with reference to FIGS. 1-5, schematic structure of the vehicle seat 1 which concerns on the Example of this invention is demonstrated. This vehicle seat 1 is a seat located in the second row among the three rows of seats (first row seat, second row seat, third row seat) provided on the vehicle floor F, It is a single seat that is independent on the left and right (see FIG. 1).

  The vehicle seat 1 includes a seat cushion 2 and a seat back (not shown). The seat cushion 2 will be described in detail below. Since the seat back may be a known one, its detailed description is omitted.

  The seat cushion 2 is provided with an ottoman 10. Here, the ottoman 10 will be described in detail. The ottoman 10 is mainly composed of an ottoman frame (not shown) constituting the skeleton and a cushion body 12 assembled to the ottoman frame and having cushioning properties. The cushion body 12 is provided with an irradiation unit 30 having an LED lamp 36 capable of emitting light (see FIG. 2).

  This description corresponds to “the ottoman is provided with a light emitter capable of emitting light” described in the claims. The irradiation unit 30 includes a substrate 32, legs 34 attached to four corners of one surface of the substrate 32, and an LED lamp 36 attached to the center of the other surface of the substrate 32.

  The irradiation unit 30 has its legs 34 joined to the tip side of the ottoman frame with screws (not shown) so that the light from the LED lamps 36 is emitted from the back surface of the cushion body 12. This description corresponds to “the illuminator is provided so as to emit light from the surface opposite to the surface on which the ottoman is placed” described in the claims. The LED lamp 36 of the irradiation unit 30 is electrically connected to a vehicle power source (not shown) via a switch (not shown). In addition, five irradiation units 30 are provided along the width direction of the cushion body 12 (see FIG. 4).

  Further, a gantry 40 formed in a substantially U-shape so as to surround the five irradiation units 30 is joined to the ottoman frame by screws (not shown) (see FIG. 3). A diffusion film (for example, a translucent thin film, a milky white frosted glass, or the like) 42 that allows light emitted from each LED lamp 36 to pass through is attached to the gantry 40. This description corresponds to “the light emitted from the light emitter is transmitted through the diffusion film” described in the claims. The cushion body 12 is configured in this way.

  The cushion body 12 configured in this way is covered by the skin 14 together with the irradiation unit 30, the mount 40 and the diffusion film 42. Therefore, the skin 14 is formed with an opening 14a through which light emitted from each LED lamp 36 passes. The ottoman 10 is configured in this way.

  The ottoman 10 configured as described above is assembled to a front portion of a cushion frame (not shown) of the seat cushion 2 via a link 20 that forms a pair on the left and right. The link 20 is mechanically fastened to an electric motor (not shown). Therefore, the link 20 can be operated by driving the electric motor. Therefore, the ottoman 10 is switched between a storage state in which the ottoman 10 is stored in the seat cushion 2 (state shown in FIG. 1) and a foot-mountable state (state shown in FIG. 5) in which the occupant seated on the seat cushion 2 can put on the legs. Can do.

  Thus, when switched to the foot-ready state, the ottoman 10 is substantially parallel to the vehicle floor F. Of course, it is possible to switch the ottoman 10 to any state between the storage state and the foot-ready state as well as the storage state and the foot-ready state. Note that the link 20 that performs this switching may be a known link, and therefore a detailed description thereof will be omitted.

  Further, the seat cushion 2 is provided with a reflection plate 50 via a bracket 52 under the cushion frame (see FIG. 1). When the ottoman 10 is in the retracted state, the reflecting plate 50 reflects the light emitted from the LED lamps 36 toward the foot space S, which is a footrest space for placing a foot of an occupant seated on the vehicle seat 1. It is provided so that it can be made. The seat cushion 2 is configured in this way.

  The vehicle seat 1 includes the seat cushion 2 and the seat back configured as described above. The vehicle seat 1 is assembled to the vehicle floor F via a slide rail (not shown). The vehicle seat 1 is configured in this way.

  Then, the effect | action of the vehicle seat 1 is demonstrated with reference to FIGS. First, a description will be given from when the ottoman 10 is in the stored state. When the switch is turned on while the ottoman 10 is in the retracted state, the light emitted from each LED lamp 36 illuminates the reflecting plate 50. Then, since this illuminated light is reflected by the reflecting plate 50, the reflected light illuminates the foot space S. Therefore, when the ottoman 10 is stored, the foot space S can be brightened, and the irradiation unit 30 can be used as a foot light (see FIG. 6).

  Next, the case where the ottoman 10 is switched from the stored state to the footable state will be described. When the ottoman 10 is switched to the footable state and the switch is turned on, the light emitted from each LED lamp 36 illuminates the vehicle floor F. Therefore, when the ottoman 10 is in a state in which the foot can be placed, the foot space S can be brightened, and the irradiation unit 30 can also be used as indirect illumination in the vehicle interior (see FIG. 7).

  The vehicle seat 1 according to the embodiment of the present invention is configured as described above. According to this configuration, the cushion body 12 of the ottoman 10 is provided with the irradiation unit 30 (LED lamp 36) that can emit light. Therefore, when light is emitted from the irradiation unit 30 (LED lamp 36), the ottoman 10 itself is illuminated. Therefore, it is easy to grasp the operating state of the ottoman 10 even in the dark. For example, even if the occupant gets on and off when the ottoman 10 is switched to the foot-ready state, the feet of the occupant getting on and off contact the ottoman 10. Can be suppressed. As a result, usability of the ottoman 10 in the dark can be improved.

  Further, according to this configuration, the irradiation unit 30 has its legs 34 joined to the front end side of the ottoman frame with screws (not shown) so that the light from the LED lamps 36 is emitted from the back surface of the cushion body 12. ing. Therefore, when light is emitted from each LED lamp 36 when the ottoman 10 is switched to the foot-mountable state, not only the ottoman 10 itself but also the foot space S can be illuminated. Moreover, if the foot space S can be illuminated in this way, the irradiation unit 30 can also be used as indirect illumination in the passenger compartment.

  Further, according to this configuration, five irradiation units 30 (LED lamps 36) are provided along the width direction of the cushion body 12. In addition, a pedestal 40 formed in a substantially U shape so as to surround the five irradiation units 30 is joined to the ottoman frame by screws (not shown). A diffusion film 42 that allows light emitted from each LED lamp 36 to pass through is attached to the gantry 40. Therefore, even if five irradiation units 30 are provided, it is possible to suppress unevenness of the light flux that occurs between adjacent irradiation units 30.

  Further, according to this configuration, the seat cushion 2 is provided with the reflecting plate 50 via the bracket 52 below the cushion frame. Therefore, when the ottoman 10 is in the stowed state, the light emitted from each LED lamp 36 can be reflected toward the foot space S side, which is a footrest space for placing a foot of an occupant seated on the vehicle seat 1. . Therefore, even if the ottoman 10 is in the stored state, the foot space S can be brightened, and the irradiation unit 30 can be used as a footlight.

  As already described, each leg 34 of the irradiation unit 30 is joined to the front end side of the ottoman frame by screws (not shown) so that the light from the LED lamp 36 is emitted from the back surface of the cushion body 12. ing. That is, the irradiation unit 30 (LED lamp 36) is provided on the front end side of the ottoman 10.

  If provided in this way, the following two effects will be provided. First, the first effect will be described. When the ottoman 10 is in the retracted state, the distance between the irradiation unit 30 and the vehicle floor F is short, so that when the irradiation unit 30 is used as a footlight, the surface of the vehicle floor F is easily illuminated. Therefore, usability as a footlight can be enhanced. On the other hand, when the ottoman 10 is in a state where the foot can be placed, the light can be delivered to the feet of the occupant.

  Next, the second effect will be described. As already described, since the ottoman 10 can be switched to any state between the stowed state and the footrest ready state, the height position of the irradiation unit 30 from the vehicle floor F is set to a desired height position. Can be set. If the height position can be set in this manner, it is effective when the shoes taken off by the occupant are sterilized using the LED lamp 36 of the irradiation unit 30. For example, when the entire shoe is to be sterilized, the removed shoe is placed in the foot space S of the vehicle floor F, the ottoman 10 can be placed on the foot, and the LED lamp 36 is turned on (see FIG. 8). Then, since the entire shoe is illuminated, the entire shoe can be sterilized.

  On the other hand, when only a part of the shoes (for example, toes) is to be sterilized intensively, the removed shoes are placed in the foot space S of the vehicle floor F, the link 20 of the ottoman 10 is operated, and the irradiation unit together with the cushion body 12 The LED lamp 36 may be turned on by bringing 30 close to the toe of the shoe (see FIG. 9). Then, since the toe of the shoe is locally illuminated, the toe of the shoe can be sterilized intensively.

The contents described above are only related to one embodiment of the present invention, and do not mean that the present invention is limited to the above contents.
In the embodiment, the vehicle seat is located in the second row among the three rows of seats (first row seat, second row seat, third row seat) provided in the vehicle (not shown). The sheet has been described as an example. However, the present invention is not limited to this, and a sheet positioned in the first row and a sheet positioned in the third row may be used.

  In the embodiment, the example in which the reflection plate 50 is provided in the lower part of the cushion frame has been described. However, the present invention is not limited to this. When the ottoman 10 is in the storage position, when the light is irradiated from the irradiation unit 30, the irradiated light is reflected toward the foot space S in front of the seat cushion 2. If possible, the reflecting plate 50 may be provided on the vehicle floor F.

  Moreover, in the Example, it demonstrated as an example the shoes which the passenger | crew took off as a target object which sterilizes. However, the object to be sterilized is not limited to this, and any object may be used.
