Hereinafter, an embodiment in which the present invention is embodied in a single seat device installed in a first class cabin in an aircraft will be described with reference to FIGS.
As shown in FIG. 1, the seat device 10 according to the present embodiment includes a partition 11 having a substantially rectangular ring shape with one side cut out in a plan view, and a seat 12 installed inside the partition 11. ing. The partition 11 includes a back shell 13 disposed so as to cover the rear and both sides of the seat 12, a front shell 14 disposed in front of the seat 12 so as to face the back shell 13, and the back shell 13. And a side shell 15 for connecting one side of the front shell 14 to each other.

  An operation panel 16 is provided on the inner surface side of the side shell 15, and various devices (for example, a seat illumination lamp and a cover device 24 described later) that the seat device 10 is equipped according to the operation content using the operation panel 16. Etc.) can be used or not used. The side where the side shell 15 is not provided in the partition 11 is the entrance 10a of the seat apparatus 10, and the entrance and exit between the interior of the seat apparatus 10 and the passage P provided beside the seat apparatus 10 through the entrance 10a. Can be done.

  On the other hand, the seat 12 includes a seat base portion 17 that is slidable in the front-rear direction via a slide mechanism (not shown), and a seat portion 18 made of a cushion material is provided on the base portion 17. . A backrest 19 that functions as a backrest is provided at the rear side edge of the seat 18 so as to be tiltable in the front-rear direction with its lower end as a fulcrum, and a headrest 20 is provided at the upper end of the backrest 19. Yes. Further, a legrest 21 is provided at the front side edge of the seat portion 18 so as to be tiltable in the front-rear direction with the upper end portion as a fulcrum, and armrests 22 are provided at the left and right side edges of the seat portion 18, respectively. A seat belt 23 is provided near the rear edge of the seat 18 so as to extend between the left and right armrests 22.

  In the seat device 10 of the present embodiment, the seat 12 is in a normal state in which the backrest 19 is substantially upright, a reclining state in which the backrest 19 is tilted backward by a predetermined angle from the normal state, and a reclining state thereof The backrest 19 is further tilted rearward so that it can take three seat modes, ie, a bed state that is substantially horizontal. Incidentally, FIG. 1 and FIG. 2 show the seat mode in the normal state, and FIGS. 4 to 6 show the seat mode in the bed state. As understood from FIG. 4 and the like, in the seat state in the bed state, the seat portion 18 and the backrest 19 are in a state in which the seat base portion 17 is slid forward from the normal state (and the reclining state). And the legrest 21 is comprised so that it may become a substantially horizontal state.

  As shown in FIGS. 1 and 2 (a) and 2 (b), the back shell 13 is formed such that the upper end surfaces 13a of the left and right side walls thereof are formed in a circular arc shape with a front lowering, and between the left and right side walls. A cover device 24 is attached to the upper end of the rear side wall connecting the two. The cover device 24 includes a horizontally long box-shaped storage box (storage section) 25 having an opening 25a formed on the front surface side, and the storage box 25 is formed into a bag shape by a flexible material. The formed cover member 26 is stored and stored. Incidentally, as the material, when the cover member 26 is molded into a bag shape, various resin materials can be used as long as the material can impart flexibility to the cover member 26. In the case of this embodiment, an example is given. Colored vinyl resin materials are used. As shown in FIG. 2 (b), the cover member 26 has a proximal end portion attached and fixed at the inner back position of the storage box 25, and the storage box 25 in a non-deployed state in which the distal end side is rolled up. It is stored and stored inside. That is, as shown in FIG. 3, spiral springs (springs) 27 are mounted on both the left and right sides of the cover member 26, and the cover member 26 is always urged by the urging force of the spiral spring 27 in the winding direction. The storage box 25 is stored and stored in a non-deployed state in a non-use state wound up in a roll shape.

  2 (a) and 2 (b), the rear side wall of the back shell 13 has a vertical pipe (fluid supply path) 28 extending in the vertical direction in the internal space between the inner panel 13b and the outer panel 13c. It is arranged along. The vertical pipe 28 has an upper end projecting into the storage box 25 and is connected to the lower surface of the base end of the bag-like cover member 26 so as to communicate with the inside of the cover member 26. Has been. On the other hand, an air compressor (fluid supply device) 29 is installed on the floor surface behind the seat 12 inside the back shell 13, and a horizontal pipe (fluid supply path) 30 is provided in the air compressor 29. Are connected. The front end of the horizontal pipe 30 penetrates the inner panel 13b of the back shell 13 and protrudes to the inner space. At the lower part of the inner space, the lower end of the vertical pipe 28 and an electromagnetic valve (valve device) 31 are provided. It is connected through.

  When the air compressor 29 is driven while the electromagnetic valve 31 is open, air (fluid) is supplied into the cover member 26 through the horizontal pipe 30 and the vertical pipe 28, and the air supply is performed. In response, the cover member 26 expands against the urging force of the spiral spring 27, and is configured to be unfolded outside the storage box 25 as shown in FIG. In that case, the cover member 26 is slidably guided to the upper end surface 13a in which the front end portion (end edge) 26a of the cover member 26 forms a front-falling arc surface shape on the left and right side walls of the back shell 13, and is shown in FIG. It becomes a state.

  Therefore, next, regarding the operation of the seat device 10 of the present embodiment configured as described above, particularly when the seat 12 is in a bed state, the operation when the cover device 24 is used. This will be described below with attention.

  Now, as shown in FIG. 4, when the seat mode is in the bed state, as described above, the seat portion 18, the backrest 19 (headrest 20), and the legrest 21 are in a substantially horizontal state. Therefore, in this state, when the person 32 using the seat device 10 brings the back 33 into contact with the backrest 19, the person 32 has a supine posture facing upward with the head portion 34 placed on the headrest 20. Become. Therefore, when another passenger (another person) walks through the passage P on the side of the seat device 10 in such a supine posture, his / her facial expression (such as a sleeping face) is looked down on by the other passenger. Become psychologically uncomfortable. Moreover, in the supine posture, the light of the seat illumination lamp provided on the ceiling of the guest room may feel dazzling. Therefore, in such a case, the person 32 in the supine posture drives the cover device 24 using the operation panel 16 provided on the side shell 15. That is, the operation panel 16 is used to perform an operation for shifting the cover member 26 from the non-deployed state of the non-use mode to the deployed state of the use mode.

  Then, based on the operation, the air compressor 29 starts to be driven, and air is supplied into the cover member 26 through the horizontal pipe 30 and the vertical pipe 28. At that time, the electromagnetic valve 31 is opened. Then, the supply of air from the air compressor 29 is received, and the cover member 26 starts to expand so that it is pulled out from the storage box 25 to the outside of the storage box 25. That is, from the base end side so as to be pulled forward from the opening 25a of the storage box 25 against the urging force of the spiral spring 27 from the non-deployed state of the unused state wound up in a roll shape by the spiral spring 27. It gradually expands and begins to shift to the deployed state of the usage mode. For example, as shown in FIG. 5, the distal end portion 26 a is still rolled up, but the proximal end portion is swelled along the upper end surface 13 a in the shape of a front descending arc surface in the back shell 13 and is in a supine posture. It begins to cover the head portion 34 of the person 32.

  Then, the air supply from the air compressor 29 is further continued, and when the air supply of a capacity set in advance according to the internal capacity of the cover member 26 is completed, the driving of the air compressor 29 is stopped. Further, the electromagnetic valve 31 is switched from the opened state to the closed state following the stoppage of driving of the air compressor 29. Then, as shown in FIG. 6, the cover member 26 hangs down to a position where the distal end portion 26a contacts the chest 35 of the person 32 in the supine posture, and the use state as shown in FIG. The expansion operation is stopped. In the deployed state of this use mode, the head portion 34 of the person 32 is covered from above and from the front by the cover member 26 including the body part above the chest 35. Even when the person 32 is covered with the cover member 26, the person 32 can form a space 40 (see FIG. 4) between the cover member 26 and ensure breathing.

  Incidentally, the space area 40 formed by the cover member 26 in cooperation with the back shell 13 inside the cover member 26 by bringing the tip end portion 26a into contact with the chest 35 of the person 32 is a kind of closed space (closed space). Area). That is, although it does not become a sealed space in a strict sense, a closed space having a smaller capacity than that of the entire cabin in which the seat device 10 is provided is still formed. For this reason, it is possible to adjust the atmosphere environment (temperature, humidity, etc.) in the closed space 40 to be different from the atmosphere environment of the entire cabin.

  Thereafter, when the cover state by the cover member 26 (the unfolded state of the use mode) is desired to be canceled, the person 32 uses the operation panel 16 to redrive the cover device 24. That is, this time, the operation panel 16 is used to perform an operation for shifting the cover member 26 from the unfolded state of the use mode to the undeployed state of the non-use mode. Then, based on the operation, the electromagnetic valve 31 is switched from the closed state to the open state, and the air filled in the cover member 26 is compressed through the vertical pipe 28 and the horizontal pipe 30. It is allowed to flow out to the machine 29 side.

  Then, air flows out from the inside of the cover member 26 through the vertical pipe 28 and the like, and the cover member 26 is wound up by the urging force of the spiral spring 27 from the expanded state of the usage mode shown in FIG. After the state, it is finally rewound to the original state (non-deployed state in a non-use state) shown in FIG. Therefore, the person 32 who is in the supine posture is released from the cover state of the cover member 26 that has covered the body part above the chest 35, and can move up.

According to the seat apparatus 10 of the said embodiment, the following effects can be acquired.
(1) When a person using the seat device 10 is in a state where the back 33 is in contact with the backrest 19 (for example, a supine posture with the seat 12 in a bed state), the chest portion 35 including his / her head portion 34 is included. The upper body part can be covered by the cover member 26 while ensuring a breathable state. Therefore, it is possible to prevent the cover member 26 from directly seeing one's own facial expression (sleeping face, etc.) from another person passing through the side passage P of the seat device 10. Accordingly, a person who uses the seat device 10 is less likely to feel psychologically uncomfortable with other people who use the other seat device 10, and uses the seat device 10 in a comfortable mood with respect for privacy. can do.

  (2) When the person 32 who uses the seat device 10 does not use the cover member 26 (cover device 24), the cover member 26 is stored in the storage box 25 provided in the back shell 13 near the seat 12. Since it can be stored, it does not obstruct the person 32 who uses the seat device 10 when sitting or leaving.

  (3) When the cover member 26 is used, the cover member 26 is directed from the inside of the storage box 25 attached to the upper portion of the rear side wall of the back shell 13 (the rear upper position of the seat 12) to the front lower side. To be displaced. For this reason, even when the cover member 26 is used in the use state while the seat 12 is in the normal state, the cover member 26 in the middle of the transition from the non-use mode to the use mode is in a state where the back 33 is in contact with the backrest 19 The head portion 34 of the person 32 in the sitting posture is not hit.

  (4) Even when a person 32 in a state where the back 33 is in contact with the backrest 19 of the seat 12 unexpectedly gets up and hits the head portion 34 against the cover member 26, the cover member 26 is flexible. Since it is made of a material having a property and is shaped by being filled with air, the head portion 34 can be prevented from receiving a strong impact. That is, since the cover member 26 has a good cushioning property due to the air filled inside, it is assumed that the head portion 34 of the person 32 collides temporarily in the seat device 10 in an aircraft that may fluctuate due to airflow. Becomes a suitable cover member 26 excellent in impact relaxation.

  (5) When it is desired to use the cover member 26 (the cover device 24), air (fluid) is supplied into the cover member 26 that is in a non-deployed state in a non-use state based on the driving of the air compressor 29. If it makes it, it can be set as the expansion | deployment state of a use aspect easily.

  (6) When it is desired to return the cover member 26 from the expanded state in which the cover member 26 is filled with air to the non-deployed state in which the cover member 26 is wound up in a predetermined direction, the air filled in the cover member 26 is discharged. Let me do it. If it does so, the cover member 26 can be rolled up to the original roll shape with the urging | biasing force of the spiral spring (spring) 27, and can be easily returned to the non-expanded state of a non-use aspect.

  (7) Air (fluid) is supplied into the cover member 26 from the air compressor (fluid supply device) 29 through the horizontal pipe (fluid supply path) 30 and the vertical pipe (fluid supply path) 28 to thereby remove the cover member 26. After setting the usage state, the electromagnetic valve (valve device) 31 is closed to block the air flow through the horizontal pipe 30 or the like. Thus, if the electromagnetic valve (valve device) 31 is closed and the flow of air is shut off, the cover member 26 is held in a shape in which the cover member 26 is in a developed state (a state in which air is filled). Can do.

  (8) When the front end (edge) 26a of the cover member 26 comes into contact with the chest 35 of the person 32 who is in the supine state with the seat 12 in the bed state, the upper body of the person 32 is covered with the cover member 26. can do.

  (9) Since the cover member 26 and the back shell 13 form a kind of closed space (closed space region), the atmosphere environment (temperature, humidity, etc.) in the space region 40 is changed to the entire cabin (outside of the cover member 26). It is also possible to adjust to a different atmosphere environment). In addition, in this case, since the space area 40 to be adjusted has a smaller capacity than the entire cabin, the atmosphere environment can be easily adjusted.

The present embodiment may be changed to another embodiment (another example) as follows.
The cover device 24 is driven to cover the head portion 34 of the person 32 in a state where the back 33 is in contact with the backrest 19 by the cover member 26 when the seat 12 is in the seat state of the bed state. Not limited to this, the seat 32 may be in a normal state or a reclining state, and may be performed when the person 32 is in a sitting posture.

  When the cover device 24 is driven to cover the head portion 34 of the person 32 in a state where the back 33 is in contact with the backrest 19 by the cover member 26, the cover device 24 can cover at least the head portion 34. If it exists, it is not limited to the body part above the chest 35, but may be a cover mode that covers the entire body.

The cover member 26 may be simply undeployed and stored in the storage box 25 without attaching the spiral spring 27.
-When making the said cover member 26 into the expansion | deployment state of a use aspect, it is also possible to utilize other fluids, such as water other than air, as a fluid supplied in order to fill the inside.

  The cover member 26 does not necessarily have to be formed entirely of a flexible material, and faces at least the front side (face) of the head portion 34 when it is in the cover mode. It is only necessary that the portion to be formed is made of a flexible material.

The cover member 26 may be configured such that a sheet body or a net body formed of a flexible material is manually pulled out from the storage box 25 and used.
The storage box 25 of the cover member 26 may be attached not to the upper end portion of the rear side wall of the back shell 13 but to the upper end portion of either the left or right side wall. In short, the attachment position of the storage box 25 can be arbitrarily changed as long as it can be pulled out from the opening 25a of the storage box 25 to cover at least the head portion 34 of the person 32 in the sitting posture or the supine posture. It is.

  In the above-described embodiment, the cover member 26 may be configured to be in an expanded state in which the inside is always filled with air (fluid) and expanded. In this case, the cover member 26 that is always in the unfolded state cannot be stored in the storage box 25 on the rear side wall of the back shell 13. For example, the inner panel 13 b and the outer surface of the rear side wall of the back shell 13 It is preferable that the internal space between the panel 13c and the like can be stored in a position that does not get in the way when the person 32 is seated on the seat 12. In such a case, there is no time for supplying the air (fluid) every time the cover member 26 is used, and thus the cover member 26 can be used quickly.

In the above-described embodiment, the cover member 26 does not necessarily have a configuration in which the cover member 26 is always connected to the air compressor (fluid supply device) 29 via the vertical pipe (fluid supply path) 28 or the like.
In the embodiment, the fluid supply device may be configured by a blower such as a blower fan instead of the air compressor 29. Further, the fluid supplied from the fluid supply device into the cover member 26 is not limited to air but may be other gas or liquid such as water. In short, the cover member 26 is supplied and filled in the cover member 26. Various fluids that can be in a deployed state are applicable.

  In the above-described embodiment, the seat device 10 is installed in the first class cabin of the aircraft. However, the present invention is not limited to this, and the seat device may be implemented in an economy class cabin. Further, the present invention may be embodied in a seat device installed in a guest room in other transportation means such as a railway vehicle, a bus, and a ship without being limited to an aircraft.
