As shown in FIG. 6, at the tip of the support leg 4, a lower end portion 4a is formed as a footrest contacting portion that abuts on an upper plate portion 5b described later of the footrest 5. The lower surface of the lower end portion 4a is formed in a spherical shape.
Thus, when the spherical lower surface of the lower end 4a of the support leg 4 abuts on the footrest 5, when the footrest 5 slides by the first slide mechanism SM1, which will be described later, the locality from the lower end 4a It is possible to prevent the footrest 5 from being damaged by the load applied to the footrest 5. The cushion frame 3 (the seat body Sb) is suitably supported by the vertical force received from the upper plate portion 5 b via the support legs 4.

The footrest 5 has a side plate portion 5c forming a side surface, and an upper plate portion 5b separately or integrally formed with the side plate portion 5c and formed to cover the upper surface of the side plate portion 5c. A plurality of support pieces 11 are attached to the upper plate 5b along the inner side surface of the side plate 5c.
The support piece 11 has a cylindrical shape and extends vertically, and a lower end portion 11b as a floor contact portion projecting downward from the lower surface of the support body 11a.
The support main body 11a is a member fixed to the upper plate 5b. The lower end portion 11 b formed on the lower surface of the support piece 11 is formed in a spherical shape. By forming the lower end portion 11 b in this manner, it is possible to prevent the local load from being applied to the floor FL from the lower end portion 11 b when the footrest 5 slides to the front and back of the vehicle seat SL, and the floor FL Can be avoided from being

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 moves the rail support foot 6 fixed to the cushion frame 3, the sliders 8 and 9 guided by the footrest rail 7 and the footrest rail 7 in the sliding direction, and the sliders 8 and 9 in the front and back direction And a motor 10 for driving the motor.

In detail, two rail support feet 6 are attached to the lower surface of the horizontally extending flat plate portion 3 a of the cushion frame 3 and extend downward.
The rear end of each of the two footrest rails 7 is attached to the lower end side of each of the two rail support legs 6, and extends to the front side of the vehicle seat SL. The lower surface of the footrest rail 7 is formed with a plurality of lower side projecting portions 7a projecting downward. The lower surface of the lower protrusion 7a is formed in a spherical shape. Thus, when the lower surface of the lower protrusion 7a is formed in a spherical shape, when the vehicle seat SL slides relative to the floor FL by the second slide mechanism SM2 described later, the lower protrusion 7a It is possible to prevent the local load from being applied to the floor FL and to prevent the floor FL from being damaged.

Each of 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 8a and 9a at the lower part of the sliders 8 and 9 are C-shaped in cross section, extend along the footrest rail 7, and slide around a part of the footrest rail 7 It is mounted movable. The fixing portions 8b and 9b at the upper portion of the sliders 8 and 9 are formed in a rectangular cross section, extend along the footrest rail 7, and are fixed to the lower surface of the upper plate portion 5b of the footrest 5. It is done.

  When the motor 10 operates, power is transmitted to the slider 8 through the gear box and the rod 10 a connected to the motor 10. The slider 8 to which the power is transmitted moves in the front-rear direction according to the control of the motor 10 by the control unit C, and moves along the footrest rail 7 with the slider 9 connected via the upper plate 5b. It will be done. 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 physical size, the footrest 5 is positioned at the front position in the seat longitudinal direction, and when the seated person is a normal physical person, the footrest 5 is in the middle position in the seat longitudinal direction When the seat occupant is a small-sized person, the footrest 5 may be positioned at the back of the seat.
In order to enable adjustment of the position of the footrest 5, if, for example, the first slide mechanism SM1 is attached to the footrest rail 7 and provided with a Hall IC sensor (not shown) for detecting the amount of rotation of the motor 10. Good. According to this configuration, the controller C can adjust the amount of rotation of the motor 10 to adjust the position of the footrest 5 according to the value detected from the Hall IC sensor.

Next, with reference to FIG. 8, the second slide mechanism SM2 for sliding the vehicle seat SL relative to the floor FL and the pivoting mechanism RM for pivoting the vehicle seat SL around the vertical axis will be described. .
FIG. 8 is a perspective view showing the second slide mechanism SM2 and the pivoting mechanism RM of the vehicle seat SL by cutting a part of the floor FL.

  The second slide mechanism SM2 is configured of a pair of lower rails 17 provided below the floor FL, and a base lower portion 18a which is a part of a base 18 to be described next slidably connected to the pair of lower rails 17. It is done.

  The base 18 is a member serving as a base of the floor FL, and has a flat base lower portion 18a, a base upper portion 18b fixed to the upper surface of the base lower portion 18a, and a pivot shaft portion 18c formed on the upper surface of the base upper portion 18b. Mainly composed of

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

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

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

Further, on the outer peripheral surface of the annular portion 3b, an abutting portion 3c formed so as to partially project in the circumferential direction is formed.
The rotation stopper 18d extends upward, that is, in the direction approaching the annular portion 3b, radially outward of the rotation shaft 18c and on the upper surface of the base upper portion 18b. The rotation stopper 18 d is for restricting rotation by abutting on the contact portion 3 c when the vehicle seat SL is rotated a predetermined amount or more.
The annular portion 3b may be rotated relative to the pivot shaft portion 18c by the driving force of a motor (not shown) under the control of the control unit C.

  Then, as described above, the notches 5a are formed at the corner portions of the footrest 5 on the vehicle seat SR side, whereby the vehicle seat SL pivots to the vehicle seat SR side about the vertical axis. In this case, interference of the footrest 5 with the vehicle seat SR can be suppressed. Therefore, it is possible to rotate the vehicle seat SL around the vertical axis without causing the vehicle seat SR to interfere with each other without greatly separating the two seats.

  Furthermore, the seat body Sb (vehicle seat SL) is perpendicular to the direction in which the vehicle seat SR faces the vehicle seat SR only when the footrest 5 is on the side close to the seat body Sb in the front-rear direction, that is, the rear side. It may be made rotatable around an axis. With such a configuration, when the seat body Sb is rotated to face the adjacent vehicle seat SR, the footrest 5 is separated from the seat body Sb, that is, on the front side. Interference with the seat SL and interference with the rotation can be avoided.

  As a specific configuration, for example, when the footrest 5 is on the rear side, a limit switch (not shown) may be provided which is turned on or off. According to the signal from the limit switch, the control unit C controls the vehicle seat SR and the vehicle seat SL so that they can turn around the vertical axis in the direction in which the vehicle seat SR and the vehicle seat SL face each other. The aspect of rotation can be realized. Note that the control unit C may perform the above control based on a signal from the Hall IC sensor without using the limit switch.

  Further, as shown in FIG. 3, when the vehicle seat SR and the vehicle seat SL are rotated in directions facing each other about the vertical axis, the footrests 5 of both the seats abut (contact) It is also possible to define the limit of the rotation range at the abutting position. Thus, when defining the limit of the rotation range, the rotation stopper 18 d and the contact portion 3 c 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 cross section IX-IX in FIG. 1 and is a view showing a cross section in the vicinity of the light emitting portion LE1. FIG. 10 schematically shows a part of the holder 32 and the diverging member 33 etc. It is a perspective view shown.

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

The light emitting unit 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 LEDs 35 are formed in a film shape, and both ends in the direction in which the holder 32 extends are around the edges (upper and lower edges) of the heat dissipation holes 32 a so as to cover the front side of a part of the heat dissipation holes 32 a described later. It is attached and held by the holder 32. The LED 35 may be attached to the periphery of the heat dissipation hole 32 a, not at both ends in the direction in which the holder 32 extends, but at both ends in the direction intersecting the direction in which the holder 32 extends.

The holder 32 is disposed between the side frame 30 provided on the seat width direction outer side of the seat back S1 and the cushion pad 31, and extends up and down along the side frame 30 as shown in FIG. ing. A plurality of heat dissipation holes 32 a for radiating heat of the LED 35 are formed on the front side of the holder 32 in the vertical direction. By forming the heat dissipation holes 32 a on the rear surface side of the LED 35, the heat generated from the LED 35 can be effectively dissipated.
Further, on the front surface 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 a soft material and made of shape-retaining silicon, and has an inner groove 33a on the rear side of the center, and is formed into a substantially arch shape in cross section and extends up and down There is. As described above, since the diverging member 33 is formed of silicon, the softness does not cause the seated person to feel discomfort even when touching the bank portion 36 with the diverging member 33, and the shape retention property of the seat back The shape of S1 can be maintained, and the design 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. By fitting the concave portion 33 b to the convex portion 32 b of the holder 32, the diverging member 33 is attached while being positioned on the holder 32.

The inner groove 33 a of the diverging member 33 is formed at a position facing the heat dissipation 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 and forming a spatial spread, it becomes easy to attach the LED 35 so as to cover the heat dissipation hole 32a.
Further, on the front surface side of the diverging member 33, a pair of front grooves 33c serving as a storage groove for storing a sewn portion 40a to be described later are formed vertically.
Thus, even if a plurality of LEDs 35 are provided to emit light in a wide range by providing the diverging member 33, intermittent light is not emitted out of the sheet, but from each of the LEDs 35. Continuous light can be emitted by the emitted light being emitted.

The transmission film 34 is made of a material that transmits light, and is sewn so as to close a slit 40 b of the skin material 40 described later. Since the transparent film 34 is attached so as to close the surface material 40, foreign matter can be prevented from entering the sheet through the slit 40b, so that the breakage of the LED 35 is prevented, and the light amount of the light generated from the LED 35 can be reduced. Can be maintained.
In addition, when the sewn portion 40a of the surface material 40 and the transmission film 34 is stored in the front groove 33c, the surface of the surface material 40 bulges due to the contact between the sewn portion 40a and the diverging member 33. Can be suppressed.

  In the surface material 40, a slit 40b is formed in a portion to be the light emitting portion LE1. That is, the slits 40 b cause the LEDs 35 provided in the vehicle seat SL to emit light to the outside of the seat through the diverging member 33 and the transmission film 34.

  Since the LEDs 35 are provided on the seatback S1 more than the seat cushion S2, the LEDs 35 can be easily viewed from a window provided in the vehicle (not shown), and the visibility from the outside of the vehicle can be improved. That is, this configuration can increase the design effect.

  In addition, as described above, the light emitting portions LE1 and LE2 (slits 40b, the transmissive film 34, and the diverging member 33) are provided on the bank portions 36 and 37 which are difficult to hide by the seated person because they are not surfaces touching the seated person. . For this reason, as compared with 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 faces to be touched by the seated person, the divergence of light is confirmed even in the state where the seated person is present. It will be easier.

<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.
As the footrest 15 includes the rubber mat 15b as described above, the footrest main body 15a can be prevented from being damaged.

Further, 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 located in the vicinity of the back surface of the seat cushion S2.
By forming the footrest main body 15a in this manner, it is possible to prevent a gap from being generated between the sheet main body Sb and the footrest 15, and to improve the design.

Although footrests 5 and 15 concerning the above-mentioned embodiment were explained as what was attached to each front side of vehicle seat SR and SL, the present invention is not limited to such composition, for example, of a sheet It may be provided on the back side.
That is, the footrest according to the present invention may be for placing the legs of those who sit on the rear seats of the vehicle seats SR and SL instead of those who sit on them.
In the case of this configuration, for example, when the vehicle seat SR, SL is turned around the vertical axis so that each of the vehicle seat SR, SL faces the opposite side (the opposite side), the rear side of the vehicle seat SR, SL The footrests provided on the will be close. Even in such a case, by forming the notches in the corner portions on the adjacent sheet side in the footrest, interference between the footrest and the footrest and the sheet main body can be prevented.

  In the above embodiment, the lower rail 17, the power supply (not shown), the motor and the like are described as being disposed below the floor FL, but if it is not necessary to consider the design, the upper portion of the floor FL It may be placed on the In this way, maintenance of each member and equipment becomes easy.

  Moreover, in the said embodiment, although C-chamfered notch 5a was demonstrated to an example as an interference suppression part, it may be formed in 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 spherically formed. Explained that it avoids the application of a static load. However, the present invention is not limited to such a configuration, and if there is no problem in terms of cost, the frictional force is reduced by adopting a free bearing (ball transfer) at the spherical portion to achieve relative movement. The configuration may be smooth.

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