FIG. 2 is an exploded perspective view of a mounting structure for the headrest 20 and the monitor main body 31. FIG. 3 is a perspective view showing an installation state of the headrest 20. FIG. 4 is a perspective view showing an installation state of the monitor main body 31. FIG. 5 is a side sectional view showing a state in which the front and rear positions of the headrest 20 are changed. FIG. 6 is a side sectional view showing a state in which the height position of the headrest 20 is raised. FIG. 7 is a side cross-sectional view showing the insertion structure of the stay 22. FIG. 8 is a side sectional view showing the stay 22 inserted.
In the following description, when referring to the “surface” with respect to structural members such as the headrest 20 and the monitor main body 31, the surface facing the outside in the assembled structure is intended. In addition, the term “rear surface” intends a surface opposite to the “front surface”. Further, the term “front” refers to a surface facing forward with respect to the installation direction of the seat 1, and the term “rear” refers to a surface opposite to the “front”.

As the seat 1 for a seat of this embodiment is well shown in FIG. 1, a monitor main body 31 is installed on an upper surface portion of a seat back 10 serving as a backrest portion. The monitor main body 31 is disposed at the position of the back surface of the headrest 20 that is also installed on the upper surface of the seat back 10. Specifically, the monitor main body 31 is arranged with the display screen 31a facing the seat for the seat (not shown) arranged on the rear side.
Here, in FIG. 2, the mounting structure of the headrest 20 and the monitor main body 31 is shown in an exploded perspective view. In addition, FIG. 3 shows the installation state of the headrest 20 alone. FIG. 4 shows the installation state of the monitor main body 31. As shown in these drawings, the headrest 20 and the monitor main body 31 are attached to the back frame 11 constituting the skeleton of the seat back 10.
Hereinafter, the mounting structure of the headrest 20 and the monitor main body 31 will be described in detail.

First, the headrest 20 and its mounting structure will be described.
That is, the headrest 20 includes a head receiving portion 21, stays 22 and 23, a support device 24, an attachment device 25, and a rear cover 26 as well shown in FIG. 2. Here, the stay 22 corresponds to the first stay of the present invention.
Specifically, the head receiving part 21 is provided with a buffer structure on the front surface part thereof, and receives and supports the rear head of the occupant. Further, as shown in FIG. 3, the head receiving portion 21 has a shape in which the back surface portion is penetrated downward, and this penetration portion is formed as a fitting recess 21a. And the side part 21b is each formed in the head receiving part 21 so that the both right and left sides of the insertion recessed part 21a may be covered.
Next, as shown in FIG. 2, the upper ends of the stays 22 and 23 are connected to the support device 24. As a result, the stays 22 and 23 and the support device 24 are assembled as an integral part having a gate shape as a whole. The stays 22 and 23 are assembled in a state where two rod-like members are suspended from the head receiving portion 21 by attaching the support device 24 to the back surface portion of the head receiving portion 21. The stays 22 and 23 assembled in this way constitute leg portions for mounting the headrest 20. That is, as shown in FIG. 3, the stays 22 and 23 are inserted into the two supports 40 and 50 installed on the upper surface of the back frame 11, thereby connecting the headrest 20 to the seat back 10. . With this connection, the headrest 20 can be held as installed on the upper surface of the seat back 10. The connection structure between the stays 22 and 23 and the supports 40 and 50 will be described later.

Here, returning to FIG. 2, the above-described support device 24 is attached to the head receiving portion 21 via the attachment device 25. The attachment device 25 is connected to a hinge portion 24a of the support device 24 so as to be pivotable. And the attachment tool 25 is integrally attached to the back surface part of the head receiving part 21, as FIG. 5 shows. As a result, the head receiving portion 21 can swing the head receiving surface (front surface) with respect to the stays 22 and 23 in the front-rear direction around the hinge portion 24a. Here, the swing motion of the head receiving portion 21 is always performed in a state in which the side surface portion 21b of the head receiving portion 21 overlaps the side surface and the surface of the front cover 36 described later. Thereby, even if the headrest 20 swings, the mounting structure portion between the stays 22 and 23 and the head receiving portion 21 is covered so that it cannot be seen from the gap between the headrest 20 and the monitor main body 31.
Next, as shown in FIG. 3, the rear cover 26 is attached to the back surface portion of the head receiving portion 21. The rear cover 26 is made of synthetic resin, and is arranged so as to cover the mounting structure portion between the stays 22 and 23 and the head receiving portion 21 described above from the rear surface side. Specifically, the rear cover 26 has a plate shape that extends in a drooping direction from the upper end of the back surface portion of the head receiving portion 21. Thereby, as shown in FIG. 6, the rear cover 26 has a gap in which the mounting structure portion between the stays 22 and 23 and the head receiving portion 21 is open above the monitor body 31 even when the headrest 20 is lifted. It is covered and hidden from the rear side so that it cannot be seen from tb.

Next, a connection structure between the stays 22 and 23 of the headrest 20 and the supports 40 and 50 will be described.
That is, first, as well shown in FIG. 2, the stays 22 and 23 have a tapered lower end portion that is a tip in the insertion direction. Accordingly, when the stays 22 and 23 are inserted into the insertion ports 41 and 51 of the supports 40 and 50, respectively, the tapered surface becomes a guide surface and the stays 22 and 23 are easily inserted. The one side stay 22 has a plurality of adjustment grooves 22a and locking grooves 22b formed along the length direction on the side surface facing the other side stay 23. Specifically, the locking groove 22b is formed at the lower position of the adjustment groove 22a formed at the lowest position. Further, the supports 40 and 50 are respectively inserted and fixed in cylindrical fixing devices 11 a fixed at two locations on the upper front side of the back frame 11.
Here, FIG. 7 shows the structure of the stay 22 and the support 40 in detail. As shown in the figure, the insertion port 41 of the support 40 is provided with a locking claw 42 that can be locked to the stay 22 and stop its movement. The locking claw 42 is normally urged and held in a state of protruding into the insertion port 41. Further, an operation knob 43 is integrally provided on the locking claw 42. The operation knob 43 can move the locking claw 42 against the above-described bias by performing an operation of pushing in the left direction in the drawing. And by the movement by this operation knob 43, the latching claw 42 can be temporarily pulled out of the mouth (virtual line state).

Therefore, the stay 22 is inserted while the operation knob 43 is pushed in, and the operation claw 42 is stopped after the lower end portion of the stay 22 has passed the locking claw 42, so that the locking claw 42 is moved to the stay 22. It can be made into the state which made it contact | abut with an outer peripheral surface and pushed away. In addition, you may comprise the latching claw 42 so that it may be pushed away directly by the tapering surface of the stay 22 inserted.
When the stay 22 is further inserted into the insertion port 41, that is, in the insertion direction S, the height positions of the locking claw 42 and the locking groove 22b coincide with each other. Thereby, the latching claw 42 enters into the latching groove 22b by its elastic restoring force, and latches into this (see FIG. 8). Here, the cross-sectional shapes of the locking groove 22b and the locking claw 42 are shown in detail in FIG. That is, the cross-sectional shape of the locking groove 22b is a U-shape in which the upper and lower surfaces forming the opening surface rise straight up in the radial direction of the stay 22. The cross-sectional shape of the locking claw 42 is a protruding shape that matches the U-shape of the locking groove 22b. Accordingly, as shown in FIG. 8, the locking of the stay 22 in the insertion direction S and the pulling-out direction H is restricted by the locking groove 22b having the above-described cross-sectional shape and the locking claw 42 being locked. It will be in the state.
Then, by pushing the operation knob 43 from the above-described locked state, the locked state between the locking claw 42 and the locking groove 22b is released. Thereby, the stay 22 can be further inserted into the insertion port 41. Therefore, when the stay 22 is inserted into the insertion port 41, the height positions of the locking claw 42 and the adjustment groove 22a coincide with each other. Thereby, the latching claw 42 enters the adjustment groove 22a by its elastic restoring force, and latches it (not shown). Here, the cross-sectional shape of the adjustment groove 22a is shown in detail in FIG. That is, the cross-sectional shape of the adjustment groove 22 a is a shape in which the upper surface forming the opening surface rises straight toward the radial direction of the stay 22. The lower surface forming the opening surface is formed as an inclined surface that gently rises toward the outer peripheral surface of the stay 22. Therefore, when the adjustment groove 22a having the above-described cross-sectional shape and the locking claw 42 are locked, the stay 22 is restricted from moving in the insertion direction S, but is allowed to move in the drawing direction H. It becomes a state.
Then, by pushing the operation knob 43 and further inserting the stay 22 from the above-mentioned locked state, the locking claw 42 can be locked in sequence with the respective adjustment grooves 22a. Thus, the installation height position of the headrest 20 can be adjusted by adjusting the insertion amount of the stay 22. When the locking claw 42 and the adjustment groove 22a are locked, the stay 22 can be pulled out from the insertion port 41 by operating the headrest 20 as it is in the pulling direction H. However, when the stay 22 is pulled out and the locking claw 42 and the locking groove 22b are locked, the pulling movement of the stay 22 is restricted. That is, with this locking structure, even when the headrest 20 is lifted in some pulling direction H in the pulling direction H, the installation state on the seat back 10 is maintained.

Next, the monitor body 31 and its mounting structure will be described.
That is, the mounting structure of the monitor body 31 includes a monitor cover 32, a mounting device 33, stays 34 and 35, and a front cover 36, as well shown in FIG. Here, the stay 34 corresponds to the second stay of the present invention.
Specifically, the monitor cover 32 is made of a synthetic resin and has a shape in which a plate material is bent in an L shape. An insertion port 32 a having a size for fitting the monitor main body 31 is formed on the rising surface side of the monitor cover 32. As shown in FIG. 1, the monitor cover 32 is assembled in a state in which the display screen 31a of the monitor body 31 is exposed from the insertion port 32a and the outer frame is covered.
Next, as shown in FIG. 2, the attachment device 33 is attached to and integrated with the back surface 31 b (front surface) of the monitor main body 31. Stays 34 and 35 are attached to the back surface 33 a of the attachment device 33.

Next, the upper ends of the stays 34 and 35 are pivotally supported by the attachment device 33 and are connected to each other. The stays 34 and 35 are assembled in a state in which two rod-like members are suspended from the monitor main body 31 when the attachment device 33 is attached to the monitor main body 31. The stays 34 and 35 assembled in this way constitute leg portions for mounting the monitor main body 31. That is, as shown in FIG. 4, the stays 34 and 35 are inserted into the two supports 60 and 70 installed on the upper surface of the back frame 11, thereby connecting the monitor main body 31 to the seat back 10. To do. With this connection, the monitor main body 31 can be held as installed on the upper surface of the seat back 10. The connection structure between the stays 34 and 35 and the supports 60 and 70 will be described later.
Next, the front cover 36 is attached to the back surface 31b (front surface) side of the monitor main body 31, as shown in FIG. The front cover 36 is made of synthetic resin, and is fitted into the monitor cover 32 and assembled integrally therewith as shown in FIG. Here, the front cover 36 is formed with a cover portion 36a that covers the mounting structure portion between the stays 34 and 35 and the monitor main body 31 from the front side. As shown in FIG. 6, the cover portion 36 a has a shape that rises in a curved shape from the lower portion of the front cover 36 upward. As a result, the cover 36a can be seen from the front side so that the attachment structure portion between the stays 34, 35 and the monitor body 31 cannot be seen from the gap tf opened below the headrest 20 even when the headrest 20 is lifted. Covered.

  As shown in FIG. 2, the front cover 36 is formed with through holes 36 b penetrating in the vertical direction at two positions on the left and right sides near the front side. The through-hole 36b allows the stays 22 and 23 of the headrest 20 to be inserted from above when the headrest 20 is installed in the seat back 10. Therefore, by inserting the stays 22 and 23 into the through holes 36b and then into the supports 40 and 50, as shown in FIG. 1, the front cover 36 is like a pedestal, and the headrest 20 is placed on the upper side thereof. Can be installed. By installing the headrest 20 in this way, the monitor main body 31 can be fitted by sliding from below into a fitting recess 21a (refer to FIG. 3 for details) formed in the back surface portion of the headrest 20. Thereby, the headrest 20 and the monitor main body 31 can be assembled in a compact form with a sense of unity. Further, by adopting the above configuration, the monitor main body 31 can be configured as a separate and independent configuration that does not follow the movement of the headrest 20 in the vertical direction. Therefore, it is not necessary to cause the movement of the monitor body 31 to follow the movement through the stay 22 or the stay 23, for example, and the wiring to the inside of the seat back 10 can be simplified.

Next, returning to FIG. 2, a connection structure between the stays 34 and 35 attached to the monitor main body 31 and the supports 60 and 70 will be described. Here, the connection structure between the stays 34 and 35 and the supports 60 and 70 has substantially the same structure as the connection structure between the stays 22 and 23 of the headrest 20 and the supports 40 and 50 described above.
In other words, the stays 34 and 35 are formed such that the lower end portion which is the tip in the insertion direction is tapered. The stay 34 on one side is formed with a locking groove 34a on the side surface facing the stay 35 on the other side. Further, the supports 60 and 70 are respectively inserted and fixed in cylindrical fixing devices 11b fixed at two positions on the upper rear side of the back frame 11.
Note that the insertion slot 61 of the support 60 is provided with a locking claw 62 and an operation knob 63 as in the configuration of the support 40 described above (see FIG. 7).
Accordingly, the stay 34 is inserted into the insertion port 61 of the support 60 and the locking claw 62 and the locking groove 34a are locked, whereby the stay 34 moves in the insertion direction S and the pulling direction H. Can be regulated. And even if the monitor main body 31 is lifted in the pulling direction H by some time, this locking structure maintains the installation state on the seat back 10.

Here, as shown in FIG. 2, release buttons 36 c and 36 d are formed on the front cover 36 described above at lower positions on both the left and right sides, respectively. As can be seen with reference to FIG. 4, the release buttons 36 c and 36 d are operated by the operation knobs 43 and 63 of the supports 40 and 60 when the front cover 36 is assembled to the monitor body 31 and installed on the seat back 10. Are respectively arranged at positions outside of. In FIG. 4, in order to express the above-described configuration in an easy-to-understand manner, the front cover 36 is lifted from the original installation state with the stays 34 and 35 inserted into the middle positions of the supports 60 and 70. . Therefore, by inserting the stays 34 and 35 further than in the state of FIG. 4, the release buttons 36 c and 36 d are arranged at positions just outside the operation knobs 43 and 63.
The release buttons 36c and 36d can be pushed by operating knobs 43 and 63, respectively. That is, the operation knobs 43 and 63 can be pushed in from the positions on the left and right sides of the front cover 36. Here, the release buttons 36c and 36d are pushed in the opposite direction. Therefore, as shown in FIG. 1, when the headrest 20 or the monitor main body 31 installed on the upper surface of the seat back 10 is removed, the release buttons 36c and 36d arranged on the left and right sides are sandwiched. By performing the push-in operation, these can be easily removed.

Then, the usage method of a present Example is demonstrated.
First, referring to FIG. 2, an attachment 33 is attached to the monitor body 31 and the stays 34 and 35 are assembled. Then, the stays 34 and 35 are inserted into the supports 60 and 70 of the back frame 11. As a result, the monitor main body 31 is installed on the upper surface of the seat back 10. Next, the monitor cover 32 is assembled from the rear side of the monitor main body 31, and the front cover 36 is assembled from the front side. Thereby, as shown in FIG. 4, each assembly member on the monitor body 31 side is assembled.
Next, returning to FIG. 2, the stays 22 and 23 assembled to the headrest 20 are inserted into the supports 40 and 50 of the back frame 11. At this time, the stays 22 and 23 are inserted into the supports 40 and 50 after passing through the through holes 36 b of the front cover 36. Thereby, as shown in FIG. 1, the headrest 20 and the monitor main body 31 are assembled in a compact form with a sense of unity.
And when removing the headrest 20 or the monitor main body 31 from the seat back 10, pushing operation of the release buttons 36c and 36d arrange | positioned in the position of the both right and left is performed. Specifically, the pushing operation is performed so that the release buttons 36c and 36d are sandwiched between both hands. Then, by lifting the headrest 20 and the monitor main body 31 together as they are, they can be easily detached from the seat back 10.

Thus, according to the vehicle seat with a monitor of the present embodiment, the mounting structure of the headrest 20 is diverted to the mounting structure of the monitor main body 31, so that the monitor main body 31 can be easily attached to the seat 1 using existing technology. The structure which can be attached can be realized at low cost.
Furthermore, since the headrest 20 and the monitor main body 31 can be easily detached from the seat 1 by the insertion structure of the stays 22 and 23 and the stays 34 and 35, the seat arrangement can be easily performed.
Further, the release buttons 36c and 36d formed on the front cover 36 allow the headrest 20 and the monitor body 31 to be removed more easily.
Further, using the back frame, the insertion ports 41 and 51 for inserting the stays 22 and 23 for mounting the headrest 20 and the insertion ports 61 for inserting the stays 34 and 35 for mounting the monitor main body 31 are used. , 71 can be set at suitable positions close to each other.

Although the embodiment of the present invention has been described with one example, the present invention can be implemented in various forms in addition to the above example.
For example, the release button is not necessarily formed on the front cover, and may be formed on another component such as a monitor cover. Alternatively, the release button may not be set, and a hole that allows the finger to reach the operation knob may be simply formed.
