Description

  The present invention relates to an aircraft seat device that is connected to the front and rear and capable of tilting a seat back.

  2. Description of the Related Art Conventionally, an aircraft seat apparatus is provided with ear supports having a function of supporting a seated person's ears and a temporal region on both sides of an upper end portion of a seat back. In addition to the above functions, the ear support has a function of blocking the field of view of the adjacent seated person to a certain extent and securing a seated person's private space.

  However, some seat devices for aircraft can tilt the seat back greatly to make the entire seat close to the bed (bed state). When such a seat device is in the bed state, the seating of the rear seat is possible. The face enters the person's field of view and other people behind him. However, the ear support as described above cannot block the view of the seated person in the rear seat. Usually, when the seat back is tilted until the seat device is in the bed state, it is often the case that the user wants to relax more than the normal seated state or sleep. However, it is harder to relax and sleep when your face is in the other person's field of view, and for the seated person in the back seat, the face of the seated person in the front seat is in front. So I can't calm down.

  Therefore, in order to solve these problems, a hood device is arranged at the back of the seat, and the seat back is moved back to the private space surrounded by the both side walls and the rear wall of the peripheral wall portion of the hood until it becomes a bed. Has been proposed (see Patent Document 1).

  That is, it is intended to secure a sufficient private space for the seated person by blocking the line of sight of the seated person in the adjacent and rear seats.

Japanese Patent Laid-Open No. 10-80336

  However, in such a conventional technique, since the hood device is arranged separately from the seat device between the front and rear seat devices in order to secure a private space, the space is sacrificed by the amount of the hood device. was there.

  In addition, the provision of the hood device has a problem that the cost increases accordingly.

  The present invention has been made paying attention to such problems of the prior art, and an object of the present invention is to provide an aircraft seat apparatus that can secure a private space by blocking the eyes of others.

The present invention operates as follows.
According to the aircraft seat device (1) of [1], the seat back (10) of the aircraft seat device (1) can be tilted into a reclining state. When the thin plate-shaped shielding sheet (100) accommodated in the seat storage portion (110) included in the seat back (10) is pulled out from the seat storage portion (110), the shielding sheet (100) is removed from the seated person. The head can be covered from the back of the head to the front of the head through the top of the head. By taking out the shielding sheet (100) from the seat storage portion (110) in the reclining state where the seat back (10) is tilted, the line of sight to the seated person's head can be blocked. Private space can be secured.

  Moreover, since the shielding sheet (100) is accommodated in the seat accommodating portion (110) provided in the seat back (10), for example, when a hood device for blocking the line of sight is provided behind the seat device There is no sacrificing space between the front and rear seating devices. Furthermore, since the sheet storage unit (110) only needs to be able to store the shielding sheet (100), it does not have a large structure and is advantageous in terms of cost. Moreover, since it does not become large-scale, it can be set as the aircraft seat apparatus (1) which does not feel uncomfortable also in design.

  According to the aircraft seat device (1) of [2], the holding members (120) arranged on both sides of the shielding sheet (100) hold a part of the thin shielding sheet (100) that can be bent. The holding member (120) can be housed in a holding member housing part (130) disposed forward from both sides of the upper portion of the seat back (10) so as to be freely inserted and removed.

  When the holding member (120) is taken out of the holding member storage part (130), at least a part of the shielding sheet (100) attached to the holding member (120) is held by the holding member (120). However, it is pulled out from the sheet storage part (110). When the shielding sheet (100) is pulled out, the seated person's head can be covered, so that the line of sight to the seated person's head can be shielded even when the seat back (10) is tilted. . Moreover, the said shielding sheet (100) attached to the said holding member (120) and hold | maintained can be reliably and easily taken out / inserted from the said sheet | seat accommodating part (110).

  Further, according to the aircraft seat device (1) of [3], a part of the thin plate-shaped shielding sheet (100) that can be bent is attached, and the side portion (101) of the shielding sheet (100) is held. A holding member storage portion (130) in which the holding member (120) can be freely inserted and retracted is located forward from both sides in the width direction of the upper portion of the seat back (10). Since the holding member (120) housed in the holding member housing portion (130) is a plate-like body and has a central axis (121) of rotation in the holding member housing portion (130), It is stored in the holding member storage portion (130) while rotating around the central axis (121), and is taken out from the holding member storage portion (130).

  A sheet front end portion (102) of the shielding sheet (100) is attached to a front end portion (122) of the holding member (120). The shielding sheet (100) is accommodated in the sheet accommodating portion (110) while being supported by the outer edge portion from the front end portion (122) to the rear end portion (123) of the holding member (120) and is taken out. . When the holding member (120) is taken out from the holding member storage part (130), the shielding sheet (100) attached to the holding member (120) is also taken out. The said shielding sheet | seat (100) can shield the eyes | visual_axis to a seated person's head. Moreover, since the holding member storage part (130) is located forward from both sides in the width direction of the upper part of the seat back (10), it is located on the side of the seated person's head. As a result, the seated person can obtain an appropriate feeling of blockage as if the head is surrounded by a hood, and thus a private space where the mood is calm can be obtained.

  The sheet storage unit (110) preferably includes a guide structure that guides the storage of the shielding sheet (100). The guide structure includes an inclined inner wall surface (112a) having an inclined inner wall surface (112) of the seat storage portion (110) and a lower inner wall surface (112b) having no inclination following the inclined inner wall surface (112a). The storage gap (111) is narrowed to a predetermined size. As a result, the shielding sheet (100) when stored in the sheet storage unit (110) is smoothly stored with the lower end being guided by the inclined inner wall surface (112a) and narrowed to the lower inner wall surface (112b). It is securely stored in the storage part (110). Thereby, it is possible to prevent the shielding sheet (100) from being inadvertently deformed when the shielding sheet (100) is stored, and the usability is improved.

  Furthermore, it is preferable that the holding member (120) or the holding member storage portion (130) is made of a semi-permeable or non-permeable material, so that the line of sight from the side toward the head of the seated person can be obtained. Since it can be shielded, the private space becomes even better.

  Furthermore, since the shielding sheet (100) is formed of a Guydac resin, the shielding sheet is excellent in impact resistance. Therefore, even if the passenger gets around and gets a hand, it is hardly damaged. Moreover, since it becomes a self-extinguishing shielding sheet, it is possible to reduce the damage caused by fire even if an unexpected accident occurs.

  According to the aircraft seat device of the present invention, it is possible to shield the line of sight to the head of the seated person by taking out the shielding sheet stored in the seat storage unit, and thus it is possible to secure a private space. .

  In addition, by providing a thin plate-shaped shielding sheet and a storage portion for storing the sheet in the seat back, a large-scale means is not required, and the space between the seat device in the rear seat is not sacrificed, and The aircraft seat apparatus is advantageous in terms of cost and has no sense of incongruity in design.

  Moreover, since the shielding sheet accommodated in the sheet accommodating portion is guided by the guide structure, it can be accommodated smoothly and reliably. Thereby, it is possible to prevent the shielding sheet from being inadvertently deformed when the shielding sheet is stored, and the usability is improved.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.
Each figure shows an embodiment of the present invention.
As shown in FIG. 1, an aircraft seat apparatus 1 according to an embodiment of the present invention (hereinafter referred to as a seat apparatus 1) includes a tiltable seat back 10, a seat bottom 20 on which a seated person sits, and a lower limb in a seated posture. Leg rest 30 for obtaining a comfortable posture and armrests 40 provided on both sides of the seat bottom 20 are provided, and a member for securing a private space is provided above the seat back 10. Yes. In FIG. 1, only the seat device 1 for two persons is illustrated. However, in the state where the seat device 1 is actually installed, the same seat device 1 is continuously provided before and after the illustrated seat device 1. Yes.

  The private space is a thin plate-shaped shielding sheet 100 that can cover a seated person's head from the back of the head to the top of the head, and further forward of the front of the head, and a part of the shielding sheet 100 is attached. The holding member 120 that holds the side portion 101 of the shielding sheet 100 and the holding member storage portion 130 that can store the holding member 120 detachably are defined. The holding member 120 taken out from the holding member storage unit 130 is like a hood together with the shielding sheet 100 to define a private space. Hereinafter, the holding member 120 is referred to as a hood frame 120, and the holding member storage portion 130 is referred to as a hood frame storage portion 130.

  As shown in FIGS. 2, 4, and 5, the seat back 10 includes a seat back frame 200. The seat back frame 200 has a U-shape, and is disposed so that the front end portion faces downward. A seat back pan 201 to which a cushion is attached is attached between the left and right side portions 200a and 200b of the seat back frame 200.

  A seat back cushion 11 for receiving a seated person's back is mounted on the front surface of the seat back pan 201. The seat back cushion 11 covers the entire front surface. The seat back cushion 11 is composed of a cushion material whose entire surface is covered with a dress cover. This cushion material is, for example, urethane foam.

  A back pad 12 extending from the lower part to the upper part is mounted on the back surface of the seat back pan 201. Above the back pad 12, a sheet storage portion 110 for storing the shielding sheet 100 is disposed.

  The seat storage portion 110 has a width that is substantially the same as the width between the side portions 200 a and 200 b of the seat back frame 200. The sheet storage unit 110 stores the shielding sheet 100 in the storage gap 111 between the resin plate-like portion and the back side of the seat back pan 201. The upper part of the sheet storage unit 110 is open along the width direction. The position of the opening is substantially the same position as the uppermost part of the seat back 10. From this opening, the shielding sheet 100 is stored in a storage gap 111 so as to be freely inserted and removed.

  The inner wall surface 112 on the back side of the sheet storage unit 110 includes an inclined inner wall surface 112a inclined from the opening and a lower inner wall surface 112b without an inclination following the inclined inner wall surface 112a. A guide structure for reliably storing in a predetermined state is formed. The inclined inner wall surface 112a is inclined so as to approach the seat back pan 201 as it falls from the opening. Accordingly, the storage gap 111 is gradually narrowed at the portion where the inclined inner wall surface 112a is widened. The lower inner wall surface 112b following the inclined inner wall surface 112a has substantially the same distance from the seat back pan 201, and the storage gap is a predetermined width. Thereby, the shielding sheet 100 when stored in the sheet storage unit 110 is smoothly stored while being guided by the lower end portion contacting the inclined inner wall surface 112a, and the lower end portion of the shielding sheet 100 is narrowed to reach the lower inner wall surface 112b. 110 is securely stored.

The shielding sheet 100 stored in the sheet storage unit 110 is formed in a thin plate shape with a semi-permeable or non-permeable resin. This shielding sheet 100 is formed by, for example, a Guydac resin having a thickness of 1 mm. The Guidac resin has a flexural modulus of about 23,000 kgf / cm ² , and the shielding sheet 100 in the present embodiment formed to a thickness of 1 mm is bent by its own weight. This Guidac resin is excellent in impact resistance and self-extinguishing. Further, in terms of workability, it is excellent in any of machining, thermal processing and adhesive processing. Since the shielding sheet 100 formed of such a Guidac resin is not easily damaged and becomes a shielding sheet having self-extinguishing properties, there is an advantage that damage can be reduced even if an unexpected fire occurs. is doing.

  A hood frame storage portion 130 for storing a hood frame 120 that holds the seat 100 is disposed from the both sides in the width direction of the upper portion of the seat back 10 to the front continuously from the seat storage portion 110. As shown in FIG. 2, the hood frame storage portion 130 is attached to the inner wall 131 attached to the side surface of the seat back frame 200 and the outer wall that is attached to the inner wall 131 and forms a predetermined space between the inner wall 131. It consists of part 132. The upper portion of the hood frame storage unit 130 is open, and the hood frame 120 is stored in the predetermined space through the opening. As will be described later, the hood frame 120 can be rotated in the hood frame storage unit 130, and by this rotation, the hood frame 120 comes out of the position stored in the hood frame storage unit 130 and the hood frame storage unit 130. It can be displaced between positions.

  A stopper 133 is attached to the upper part of the inner surface of the outer wall portion 132. A stopper 134 is attached to the lower side. The stopper 133 rotates in the direction in which the hood frame 120 comes out of the hood frame storage unit 130 (direction of arrow A, see FIG. 5), and comes into contact with a part of the hood frame 120 when it is pulled out to the maximum. The rotation of the hood frame 120 in the arrow A direction is limited.

  On the other hand, when the hood frame 120 is rotated in the direction opposite to the direction of the arrow A and is completely stored in the hood frame storage unit 130, the stopper 134 is brought into contact with the hood frame 120 to thereby change the direction of the arrow A. The rotation of the hood frame 120 in the opposite direction is limited. A cushion (not shown) is attached to a portion where the stopper 134 contacts the hood frame 120. The material of this cushion is, for example, urethane foam. This cushion makes it difficult to transmit the shock when the hood frame 120 hits the stopper 134 to the seated person. The hood frame storage portion 130 is made of a semi-permeable or non-permeable resin. Therefore, the hood frame storage unit 130 can block the eyes of others from the side of the seated person.

  The hood frame storage unit 130 includes a lock device (not shown) for fixing the hood frame 120 immovably. A lock button for operating the lock device is provided on the outer surface of the inner wall 131. The locking device has, for example, a hook-shaped portion that is locked to a part of the hood frame 120 in the hood frame storage portion 130, and this hook-shaped portion is interlocked with the operation of the lock button. It is possible to lock the hooked portion and the locked portion of the hood frame 120 or release the locked state by operating the lock button. In the locking device, the hook-shaped portion is locked to the hood frame 120 when the hood frame 120 is pulled out from the hood frame storage portion 130 to the maximum extent. The hood frame 120 is provided with a plurality of locked portions. The hood frame 120 may be selectively fixed in a plurality of pulled out states by allowing the hook-shaped portion to be selectively locked to the plurality of locked portions. The locking device is set so that it will not be released even when a heavy load (for example, about 25 pounds) is applied. The hood frame 120 can be used as a handle for maintaining the posture.

  The hood frame 120 stored in the hood frame storage unit 130 is a plate-like body, and has a curved portion close to an arc shape at a part of the outer edge portion. The hood frame 120 is formed of a semi-permeable or non-permeable resin. The curved portion of the outer edge portion is a portion that protrudes outside the hood frame storage portion 130 when the hood frame 120 is pulled out from the hood frame storage portion 130 to the maximum extent. A flange projecting toward the inner wall 131 is formed along the curved portion.

  The hood frame 120 has a central axis 121 of rotation in the hood frame storage part 130, and the central axis 121 is attached to the inner wall part 131. Both end portions of one support arm 124 are fixed to the front end portion 122 of each hood frame 120. Thereby, while food frame 120 is supported, it can rotate integrally. Further, both end portions of one sheet mounting plate 125 are fixed to the flanges of the respective front end portions 122.

  The sheet attachment plate 125 is made of resin or metal. Both sides of the sheet leading end 102 of the shielding sheet 100 are sandwiched between the sheet attaching plate 125 and the flange, and the sheet attaching plate 125 is fixed to the flange together with the shielding sheet 100 by bolts. At the center front end portion of the seat mounting plate 125, there is provided a knob portion 126 having a shape that can be easily picked up with a finger so that the hood frame 120 can be easily taken in and out of the hood frame storage portion 130.

  As shown in FIG. 4, when the hood frame 120 is completely stored in the hood frame storage unit 130, a part of the hood frame 120 is in contact with the stopper 134 as described above. For this reason, the hood frame 120 does not enter the hood frame storage unit 130 beyond the illustrated state. In this stored state, the front end 122 is substantially at the same position as the opening of the hood frame 120. At this time, the shielding sheet 100 is stored in a state of being hung down in the storage gap 111 inside the sheet storage unit 110.

  As shown in FIG. 5, when the hood frame 120 is fully extended from the hood frame storage portion 130, a part of the hood frame 120 is in contact with the stopper 133. As a result, the hood frame 120 is prevented from further rotating in the direction of exiting the hood frame storage unit 130 (the direction of arrow A). At the same time, the locking device prevents the hood frame 120 from rotating in the direction opposite to the arrow A direction. Thereby, the state of the hood frame 120 shown in FIG. 5 is maintained.

  Since the seat front end 102 is fixed to the hood frame 120 as described above, when the hood frame 120 is taken out from the hood frame storage unit 130, the flange at the outer edge from the front end 122 to the rear end 123 is provided. Thus, both sides of the shielding sheet 100 can be supported. When the hood frame 120 is stored in the hood frame storage unit 130, the shielding sheet 100 is stored in a state of being hung from the seat mounting plate 125 into the sheet storage unit 110. As described above, the hood frame 120 is also formed of a semi-permeable or non-permeable resin. Therefore, when the hood frame 120 is taken out from the hood frame storage portion 130, the hood frame 120 can be moved from the side of the seated person's head. The person's line of sight can be blocked. Thereby, the shielding sheet 100, the hood frame 120, and the hood frame storage part 130 surround the seated person's head like a hood to form a private space that blocks the line of sight from others.

  The shielding sheet 100 and the flange may be fixed not only on both side portions of the sheet leading end portion 102 but also on the entire side portion supported by the flange.

Next, the operation will be described.
When the seat back 10 of the seat device 1 is largely tilted to enter the reclining state, the top of the head falls within the range where the line of sight of the seated person in the rear seat extends naturally. Moreover, it becomes easy to receive the gaze of the seated person of the adjacent seat. In order to block these lines of sight, the hood frame 120 housed in the hood frame housing portion 130 is pulled out from the hood frame housing portion 130 and the shielding sheet 100 is pulled out from the seat housing portion 110 as shown in FIG. The private space that shields the eyes of others can be formed around the part. At this time, the shielding sheet 100 can be easily pulled out by picking and pulling the knob 126 provided on the sheet mounting plate 125.

  As shown in FIG. 5, when the hood frame 120 is pulled out to the maximum extent from the hood frame storage portion 130, the stopper 133 comes into contact with a part of the hood frame 120 to make it impossible to draw the hood frame 120 any further. At the same time, the hook portion of the locking device is locked to the hood frame 120 to prevent the hood frame 120 from rotating in the direction in which the hood frame 120 returns into the hood frame storage portion 130 (the direction opposite to the arrow A direction). Thereby, the hood frame 120 is maintained in the most pulled out state.

  The state where the hood frame 120 is pulled out to the maximum is shown in FIG. 1, FIG. 3, FIG. 5 and FIG. As described above, the shielding sheet 100 is supported by the flange at the outer edge from the front end 122 to the rear end 123 of the hood frame 120. For this reason, the shielding sheet 100 covers the area from the upper back of the seated person to the upper front of the head along the shape of the outer edge, and blocks the eyes of others.

  As shown in FIG. 6, even if the seat back 10 is tilted to the maximum extent, the line of sight of the seated person in the rear seat is not blocked by the shielding sheet 100 and reaches the top of the head. At this time, as shown in FIGS. 3 and 5, the front end 122 of the hood frame 120 is positioned sufficiently high from the top of the seat back 10, so that the seated person feels a sense of pressure in the direction of the top of the head. There is nothing.

  Further, when the hood frame 120 is pulled out to the maximum extent, the hood frame 120 and the hood frame storage unit 130 can block the line of sight from the side of the seated person's head. Since the hood frame 120 and the hood frame storage portion 130 are located on both sides in the width direction of the upper portion of the seat back 10 as shown in FIG. 3, the seated person does not feel a sense of pressure on the side of the head. A moderate occlusion can be obtained.

  When the hood frame 120 is stored in the hood frame storage portion 130, the lock button is operated to release the hook-shaped portion locked to the hood frame 120 and then the hood frame 120 is returned to the storage direction. It's okay.

  The hood frame 120 forms a guide rail along the outer edge part from the front end part 122 to the rear end part 123 of the outer edge part or halfway to the rear end part 123 so that the shielding sheet 100 is supported by the guide rail. It may be. Further, although the front end portion 102 of the shielding sheet 100 is fixed to the seat mounting plate 125, the seat mounting plate 125 may be moved in the guide rail without being fixed to the front end portion 122 of the hood frame 120. In the state in which the hood frame 120 is stored in the hood frame storage unit 130, the seat mounting plate 125 is in contact with the tip end portion 122 in the guide rail, so that the shielding sheet 100 is held from the sheet storage unit 110 with the knob 126. By pulling out, the hood frame 120 is also pulled out from the hood frame storage portion 130 in the direction of arrow A. When each of the shielding sheet 100 and the hood frame 120 is stored, if the hood frame 120 is rotated so as to be stored in the hood frame storage unit 130, the seat mounting plate 125 is pushed by the leading end portion 122 and is moved into the sheet storage unit 110. Stored.

  Although the shielding sheet 100 has been described as being stored in a state of hanging in the storage gap 111 inside the sheet storage unit 110, the shielding sheet 100 may be stored in a bellows shape. Thereby, since the storage amount of the shielding sheet 100 can be increased without changing the storage area of the shielding sheet 100, for example, the shielding range by the shielding sheet 100 can be expanded to hide the seated person's face. .

  Further, when the locking device is engaged with the hood frame 120 and a force greater than or equal to a predetermined direction in which the hood frame 120 is stored in the hood frame storage unit 130 is applied to the hood frame 120, You may set so that the latching of the food frame 120 may be cancelled | released.

  As described above, according to the aircraft seat device 1 of the present invention, the shielding sheet 100, the hood frame 120, and the hood frame storage unit 130 are provided by pulling out the hood frame 120 from the hood frame storage unit 130 to the maximum extent. While blocking the line of sight of others who reach the head except for the front of the seated person's head, a comfortable private space with a moderate occlusion is secured around the head. Thereby, the seated person can relax the body by the seat device 1 in the reclining state and can relax the mind by a comfortable private space.

  In addition, the seat back 10 includes a seat storage unit 110 and a hood frame storage unit 130 at the top, the shielding sheet 100 is stored in the seat storage unit 110, and the hood frame 120 is stored in the hood frame storage unit 130. Unlike the case where the hood device is disposed behind the device, a comfortable living space can be maintained without sacrificing the space between the front and rear seat devices, and the shielding sheet 100 and the hood frame 120 are stored. When they are fully stowed, they do not look bad when not in use.

  Further, since the sheet storage unit 110 only needs to be able to store the thin shielding sheet 100 having a width approximately equal to the width of the seat back 10, the structure does not become large and is used manually, which is advantageous in terms of cost. In addition, it is possible to provide an aircraft seat device that does not feel uncomfortable in design.

  Further, a member serving as a cushion may be attached to the outer surface of the inner wall 131 of the hood frame storage unit 130, that is, the surface facing the side of the seated person to enhance the function as an ear support.
