Hereinafter, vehicle seats SR and SL and a vehicle seat set SS according to an embodiment of the present invention will be described with reference to the drawings.

(About overall structure)
First, the overall configuration of the vehicle seat set SS according to the present embodiment will be described with reference to FIGS.
FIG. 1 is a perspective view of a vehicle seat set SS according to an embodiment of the present invention, and FIG. 2 is a perspective view showing a state where two vehicle seats SR and SL constituting the vehicle seat set SS are separated from each other. FIG. 3 is a perspective view showing a state in which the two vehicle seats SR and SL constituting the vehicle seat set SS are rotated in a direction facing each other.

A vehicle seat set SS as a vehicle seat set is composed of two vehicle seats SR and SL arranged adjacent to each other in the seat width direction.
The vehicle seat SR and the vehicle seat SL are formed so as to be rotatable around a vertical axis by a rotation mechanism, which will be described later, and in the traveling direction of the vehicle by a second slide mechanism SM2, which will be described later. It is movable in an oblique direction with respect to a certain front-rear direction. The vehicle seat SR and the vehicle seat SL have a symmetrical shape, and the vehicle seat SL will be mainly described in order to avoid overlapping description.
The vehicle seat SL includes a seat body Sb and a footrest 5 attached to the lower side and the front side of the seat body Sb.

  The seat body Sb includes a seat back S1 that serves as a seat back for the seated person, a seat cushion S2 that serves as a seat for the seated person, and a headrest S3 that supports the head of the seated person.

Light emitting portions LE1 and LE2 are provided on the bank portions 36 and 37 on the opposite side of the adjacent vehicle seat SR among the seat width direction outer sides of the seat back S1 and the seat cushion S2.
The light emitting part LE1 is provided so as to extend vertically on the seat back S1, and the light emitting part LE2 is provided so as to extend forward and backward on the seat cushion S2. Details of these will be described later.

  The footrest 5 is a plate-like member formed in a substantially trapezoidal shape in which the seat body Sb side that is the rear side in a plan view is a long lower side and the front side is a short upper side. In other words, the footrest 5 is formed with a C-chamfered cutout 5a as an interference suppression portion at the corner portion on the front side of the seat main body Sb and on the adjacent vehicle seat SL side.

Further, the footrest 5 is configured to be movable (slidable) in the front-rear direction as shown in FIGS. 1 and 2 by a first slide mechanism SM1 described later. The detailed configurations of the footrest 5 and the first slide mechanism SM1 will be described later.
Further, the vehicle seats SR and SL are separated from each other by a second slide mechanism SM2, which will be described later, so that the distance between the vehicle seat SR and the vehicle seat SL is lowered in the oblique direction with respect to the front-rear direction. It is configured to be movable so as to leave.
Furthermore, the vehicle seats SR and SL are configured to be rotatable about a vertical axis as shown in FIGS. 1 and 3 by a rotation mechanism RM described later.

(About each configuration)
Next, each configuration of the vehicle seat set SS and the vehicle seats SR and SL will be described in detail.
First, the seat frame 1, the footrest 5, and the first slide mechanism SM1, which are the framework of the seat body Sb, will be described with reference to FIGS.
4 is a perspective view showing the seat frame 1 and the footrest 5 of the vehicle seat SL, FIG. 5 is a perspective view showing the internal configuration of the cushion frame 3 and the footrest 5, and FIG. FIG. 7 is a perspective view illustrating the inside of the footrest 5 with the upper plate portion 5b of the footrest 5 omitted.

As shown in FIG. 4, the seat frame 1 mainly includes a back frame 2, a cushion frame 3, and support legs 4.
The support leg 4 is formed so as to be bent upwardly, and is attached to the front side of the cushion frame 3 and the outside in the seat width direction (in other words, the side separated from the adjacent vehicle seat SR). Yes.
As shown in FIG. 6, a lower end portion 4 a as a footrest abutting portion that abuts on an upper plate portion 5 b (described later) of the footrest 5 is formed at the tip of the support leg 4. The lower surface of the lower end 4a is formed in a spherical shape.
As described above, the spherical lower surface of the lower end portion 4a of the support leg 4 is in contact with the footrest 5, so that when the footrest 5 is slid by the first slide mechanism SM1 described later, the lower end portion 4a is locally exposed. It is possible to avoid the footrest 5 from being damaged due to the load being applied to the footrest 5. The cushion frame 3 (the seat body Sb) is suitably supported by the vertical drag received from the upper plate portion 5b via the support legs 4.

The footrest 5 includes a side plate portion 5c that forms a side surface, and an upper plate portion 5b that is formed separately from or integrally with the side plate portion 5c and covers the upper surface of the side plate portion 5c. A plurality of support pieces 11 are attached to the upper plate portion 5b along the inner surface of the side plate portion 5c.
The support piece 11 is formed of a columnar support body 11a extending vertically and a lower end part 11b as a floor contact part protruding downward from the lower surface of the support body 11a.
The support body 11a is a member fixed to the upper plate portion 5b. The lower end portion 11b formed on the lower surface of the support piece 11 is formed in a spherical shape. By forming the lower end portion 11b in this way, when the footrest 5 slides forward and backward of the vehicle seat SL, a local load is prevented from being applied to the floor FL from the lower end portion 11b, and the floor FL It is possible to avoid scratches on the surface.

The footrest 5 is configured to be movable in the front-rear direction by a first slide mechanism SM1 provided below.
The first slide mechanism SM1 is a rail support foot 6 fixed to the cushion frame 3, a footrest rail 7, sliders 8 and 9 guided in the sliding direction by the footrest rail 7, and the sliders 8 and 9 are moved in the front-rear direction. And a motor 10 to be operated.

Specifically, two rail support legs 6 are attached to the lower surface of the flat plate portion 3a that extends horizontally of the cushion frame 3, and extend downward.
The rear ends of the two footrest rails 7 are respectively attached to the lower ends of the two rail support feet 6 and extend to the front side of the vehicle seat SL. A plurality of lower protrusions 7 a that protrude downward are formed on the lower surface of the footrest rail 7. The lower surface of the lower protrusion 7a is formed in a spherical shape. Since the lower surface of the lower protruding portion 7a is formed in a spherical shape in this way, the lower protruding portion 7a when the vehicle seat SL slides with respect to the floor FL by the second slide mechanism SM2 described later. Therefore, it is possible to avoid applying a local load to the floor FL and to prevent the floor FL from being damaged.

Each of the two sliders 8 and 9 is slidably attached to the upper surface side of each of the two footrest rails 7. The sliders 8 and 9 are fixed to the lower surface of the upper plate portion 5 b of the footrest 5.
The guide portions 8 a and 9 a at the lower part of the sliders 8 and 9 are formed in a C-shaped cross section and extend along the footrest rail 7, and slide around the footrest rail 7. It is mounted movably. Further, the fixing portions 8b and 9b on the upper portions of the sliders 8 and 9 have a square cross section and extend along the footrest rail 7, and are fixed to the lower surface of the upper plate portion 5b of the footrest 5. Has been.

  Power is transmitted to the slider 8 through a gear box and a rod 10a connected to the motor 10 when the motor 10 operates. The slider 8 to which power is transmitted in this way moves in the front-rear direction in accordance with the control of the motor 10 by the control unit C, and moves along the footrest rail 7 together with the slider 9 connected via the upper plate portion 5b. Will be. As the sliders 8 and 9 move, the footrest 5 fixed to the sliders 8 and 9 slides in the front-rear direction.

In particular, when the seated person is a person with a large physique, the footrest 5 is positioned at the front side in the front-rear direction of the seat, and when the seated person is a normal physique, the footrest 5 is positioned at the middle position in the front-rear direction of the seat. When the seated person is a person with a small physique, the footrest 5 may be positioned at a position on the rear side in the seat front-rear direction.
In order to make it possible to adjust the position of the footrest 5, for example, the first slide mechanism SM1 is attached to the footrest rail 7 and includes a Hall IC sensor (not shown) that detects the rotation amount of the motor 10. Good. According to this configuration, the control unit C can adjust the position of the footrest 5 by adjusting the rotation amount of the motor 10 according to the value detected from the Hall IC sensor.

Next, the second slide mechanism SM2 that slides the vehicle seat SL with respect to the floor FL and the rotation mechanism RM that rotates the vehicle seat SL about the vertical axis will be described with reference to FIG. .
FIG. 8 is a perspective view showing the second slide mechanism SM2 and the rotation mechanism RM of the vehicle seat SL with a part of the floor FL cut.

  The second slide mechanism SM2 includes a pair of lower rails 17 provided below the floor FL, and a base lower portion 18a that is slidably connected to the pair of lower rails 17 and is a part of a base 18 described below. Has been.

  The base 18 is a member serving as a base of the floor FL, and includes a flat base lower portion 18a, a base upper portion 18b fixed to the upper surface of the base lower portion 18a, and a rotating shaft portion 18c formed on the upper surface of the base upper portion 18b. And mainly consists of

A pair of upper rails (not shown) that slide in the pair of lower rails 17 are formed in the base lower portion 18a.
The base upper portion 18b has a substantially inverted U-shaped cross section and is formed to extend in the sliding direction side.
The rotation shaft portion 18 c is formed integrally with the base upper portion 18 b and has a cylindrical shape extending vertically, and constitutes a rotation mechanism RM described later with respect to the base 18.

Further, a bracket 19 for holding a seat slide motor, a power source, and a Hall IC sensor (not shown) is attached to the lower surface of the base 18.
In the second slide mechanism SM2, the control unit C specifies the slide position of the vehicle seat SL (seat body Sb) by detecting the rotation amount of the seat slide motor by a Hall IC sensor (not shown), The seat slide motor is controlled based on the identified slide position. In this way, the slide position of the vehicle seat SL is adjusted electrically.

The rotation mechanism RM includes a rotation shaft portion 18 c that is a part of the base 18 and an annular portion 3 b that is a part of the cushion frame 3.
The annular portion 3b has a cylindrical shape extending downward from the center portion of the lower surface of the flat plate portion 3a, and the inner peripheral surface of the annular portion 3b is along the outer peripheral surface of the rotating shaft portion 18c. The rotary shaft 18c is attached from above so as to be slidable in the circumferential direction.
The annular portion 3b and the rotation shaft portion 18c are connected so as to be smoothly rotatable via a bearing (not shown).

Furthermore, the contact part 3c formed so that it might protrude in the circumferential direction was formed in the outer peripheral surface of the cyclic | annular part 3b.
Then, the rotation stopper 18d extends outwardly in the radial direction from the rotation shaft portion 18c and on the upper surface of the base upper portion 18b so as to extend upward, that is, in a direction close to the annular portion 3b. The rotation stopper 18d is for restricting rotation by contacting the contact portion 3c when the vehicle seat SL rotates more than a predetermined amount.
The annular portion 3b may be rotated relative to the rotation shaft portion 18c by the driving force of a motor (not shown) under the control of the control unit C.

  As described above, the notch 5a is formed in the corner portion of the footrest 5 on the vehicle seat SR side, so that the vehicle seat SL rotates around the vertical axis toward the vehicle seat SR. At this time, the footrest 5 can be prevented from interfering with the vehicle seat SR. For this reason, it is possible to rotate the vehicle seat SL about the vertical axis without interfering with the vehicle seat SR without greatly separating the two seats.

  Further, the seat main body Sb (vehicle seat SL) is vertical in a direction facing the vehicle seat SR only when the footrest 5 is on the side close to the seat main body Sb in the front-rear direction, that is, on the rear side. You may enable it to rotate around an axis. With such a configuration, when the seat body Sb is rotated so as to face the adjacent vehicle seat SR, the footrest 5 is separated from the seat body Sb, that is, on the front side. It is possible to avoid interference with the sheet SL and hindering rotation.

  As a specific configuration, for example, a limit switch (not shown) that is turned on or off when the footrest 5 is on the rear side may be provided. In response to a signal from the limit switch, the control unit C performs control so that the vehicle seat SR and the vehicle seat SL can rotate around the vertical axis in a direction in which the vehicle seat SR and the vehicle seat SL face each other. A mode of rotation can be realized. In addition, you may make it the control part C perform the said control based on the signal by a Hall IC sensor not using a limit switch.

  Further, as shown in FIG. 3, when the vehicle seat SR and the vehicle seat SL are rotated in a direction facing each other about the vertical axis, the footrests 5 of both seats come into contact (contact). Then, the limit of the rotation range may be defined at the abutting position. In this way, when the limit of the rotation range is defined, the rotation stopper 18d and the contact portion 3c are not essential components.

  Next, the light emitting portions LE1 and LE2 provided in the vehicle seat SL will be described with reference to FIGS. 9 and 10 in addition to FIG. 9 is a view showing the front side of the IX-IX cross section of FIG. 1, showing a cross section in the vicinity of the light emitting portion LE1, and FIG. 10 schematically shows a part of the holder 32, the diverging member 33 and the like. It is a perspective view shown.

The light emitting portions LE1 and LE2 are provided on the bank portions 36 and 37 as corner portions on the opposite side of the adjacent vehicle seat SR among the seat width direction outer sides of the seat back S1 and the seat cushion S2 of the vehicle seat SL. Are provided.
In the following, since the configurations of the light emitting unit LE1 and the light emitting unit LE2 are substantially the same, only the light emitting unit LE1 will be described, and the description of the light emitting unit LE2 will be omitted.

The light emitting portion LE1 mainly includes an LED 35 that is a light emitting member, a holder 32 that holds the LED 35, a diverging member 33 that diverges light, and a transmissive film 34 that transmits light.
The LED 35 is formed in a film shape, and both ends in the direction in which the holder 32 extends extend around the edges (upper and lower edges) of the heat radiation hole 32a so as to cover a part of the front surface side of the heat radiation hole 32a described later. It is attached and held by the holder 32. In addition, LED35 may be attached to the circumference | surroundings of the heat radiation hole 32a not the both ends of the direction where the holder 32 extends but the both ends of the direction which cross | intersects the direction where the holder 32 extends.

The holder 32 is disposed between the side frame 30 and the cushion pad 31 provided outside the seat back S1 in the seat width direction, and extends vertically along the side frame 30 as shown in FIG. ing. On the front side of the holder 32, a plurality of heat radiation holes 32a for radiating the LEDs 35 are formed in the vertical direction. Since the heat radiation hole 32a is formed on the rear surface side of the LED 35, the heat generated from the LED 35 can be effectively radiated.
Further, on the front side of the holder 32, convex portions 32b for attaching the diverging member 33 are formed on both sides of the heat dissipation hole 32a.

The diverging member 33 is made of a soft material and is made of silicon having a shape-retaining property, and has an inner groove 33a on the back side of the center. Yes. As described above, since the diverging member 33 is formed of silicon, the softness of the diverging member 33 does not cause a sense of incongruity to the seated person even if the bank portion 36 with the diverging member 33 is touched. The shape of S1 can be maintained and the designability can be maintained.
Further, on the rear surface side of the diverging member 33, concave portions 33b are formed on both sides of the inner groove 33a. The diverging member 33 is positioned and attached to the holder 32 by fitting the concave portion 33 b to the convex portion 32 b of the holder 32.

The inner groove 33 a of the diverging member 33 is formed at a position facing the heat radiating hole 32 a when the diverging member 33 is attached to the holder 32. By forming the inner groove 33a in the diverging member 33, a spatial expansion is formed, so that the LED 35 can be easily mounted so as to cover the heat radiating hole 32a.
In addition, a pair of front grooves 33c as upper and lower grooves are formed on the front side of the diverging member 33 as receiving grooves for receiving a sewing portion 40a described later.
Thus, by providing the diverging member 33, even if a plurality of LEDs 35 are provided to radiate light in a wide range, intermittent light is not emitted out of the sheet, but from each LED 35. A continuous light can be emitted by diverging the emitted light.

The transmission film 34 is made of a material that transmits light, and is sewn so as to close a slit 40b of a skin material 40 described later. Since the transmissive film 34 is attached so as to block the skin material 40, foreign matter can be prevented from entering the sheet through the slit 40b, so that the LED 35 can be prevented from being damaged, and the amount of light generated from the LED 35 can be reduced. Can be maintained.
Further, the sewn portion 40a of the skin material 40 and the transmissive film 34 is accommodated in the front groove 33c, whereby the sewn portion 40a and the diverging member 33 come into contact with each other, thereby causing the skin material 40 to bulge to the outside of the seat. Can be suppressed.

  In the skin material 40, a slit 40b is formed at a portion that becomes the light emitting portion LE1. That is, the slits 40 b are generated from the LEDs 35 provided in the vehicle seat SL, and light is emitted outside the seat through the diverging member 33 and the transmission film 34.

  Since the LED 35 is provided in the seat back S1 rather than the seat cushion S2, the LED 35 can be easily seen from a window provided in a vehicle (not shown), and visibility from outside the vehicle can be improved. That is, with this configuration, the design effect can be increased.

  Further, as described above, the light emitting portions LE1 and LE2 (the slit 40b, the transmission film 34, and the diverging member 33) are provided on the bank portions 36 and 37 that are not a surface that touches the seated person and are not easily hidden by the seated person. . For this reason, the light divergence is confirmed even in the state where the seated person is present, compared to the case where the light emitting portions LE1 and LE2 are provided on the center side of the vehicle seats SR and SL which are the surfaces touched by the seated person. It becomes easy.

<Modification>
Finally, a footrest 15 according to a modification will be described with reference to FIG. FIG. 11 is a perspective view showing a footrest 15 according to a modification.
The footrest 15 includes a footrest main body 15a corresponding to the footrest 5 and a rubber mat 15b integrally formed on the footrest main body 15a.
Thus, it can suppress that the footrest main body 15a is damaged because the footrest 15 is provided with the rubber mat 15b.

The footrest 15 is formed longer in the front-rear direction than the footrest 5 so that the rear end of the footrest main body 15a is positioned in the vicinity of the back surface of the seat cushion S2.
Thus, by forming the footrest main body 15a, it can prevent that a clearance gap arises between sheet | seat main body Sb and the footrest 15, and can improve design property.

Although the footrests 5 and 15 according to the above embodiment have been described as being attached to the front sides of the vehicle seats SR and SL, the present invention is not limited to such a configuration. It may be provided on the rear side.
That is, the footrest according to the present invention may be for placing a foot of a person seated in the rear seat instead of a seated person of the vehicle seats SR and SL.
In the case of this configuration, for example, when the vehicle seats SR and SL are rotated around the vertical axis so that each of the vehicle seats SR and SL faces the opposite side (opposite side), the rear side of the vehicle seats SR and SL The footrests provided in are close to each other. Even in such a case, the notch is formed in the corner portion on the adjacent sheet side in the footrest, so that the interference between the footrest and the footrest and the seat body can be prevented.

  In the above-described embodiment, the lower rail 17, the power source and the motor (not shown) are described as being disposed below the floor FL. However, if it is not necessary to consider the design, the upper portion of the floor FL You may make it mount. If it does in this way, maintenance of each member and apparatus will become easy.

  In the above-described embodiment, the C chamfered cutout 5a has been described as an example of the interference suppression unit. However, it may be formed in an R chamfered shape.

  Further, the tip of the support leg 4, the lower surface of the footrest contact portion, the lower end portion 11b of the support piece 11, and the lower surface of the lower protrusion 7a of the footrest rail 7 are formed in a spherical shape. It was explained that a general load was avoided. However, the present invention is not limited to such a configuration, and if there is no problem in cost, the frictional force is reduced by adopting a free bearing (ball transfer) in the portion forming the spherical surface, and relative movement is achieved. The structure which makes it smooth may be sufficient.

  In the present embodiment, the vehicle seat has been described. However, the present invention is not limited to the vehicle seat, and may be applied to a seat generally used for a vehicle such as a ship, a train, an airplane, or an industrial machine.
