Description

  The present invention relates to an aircraft seat device capable of changing a seat posture by displacing a displaceable seat constituent member.

  Conventionally, in aircraft operation, the aircraft seat device is in an upright state in which the seat posture is not tilted at all during the three time zones of takeoff, landing, and running on the runway for passenger safety considerations. It was necessary to keep it. Whether or not the seat posture is in the upright state has been confirmed visually by a cabin attendant (CA). It is also conceivable that a sensor is provided in the seat device, and the presence or absence of tilting of the seat posture is detected by the sensor to determine whether or not it is in the upright state.

  As a prior art for confirming the angle of a seat device, there is a technology related to a child seat installed on a vehicle seat (see Patent Document 1). The child seat includes a seat body, a receiving base for receiving the seat body, and an installation angle adjusting mechanism portion rotatably provided at a lower portion of the receiving base. The receiving base and the installation angle adjusting mechanism portion are provided on the vehicle seat. It can be placed on the seat bottom. That is, it is a child seat in which the installation angle can be adjusted for vehicle seats having different inclination angles.

Japanese Patent Laid-Open No. 11-291799

  However, in the CA visual check, if the seat posture is greatly tilted, it is easy to confirm whether the seat is in the upright state or not, but it cannot be clearly determined that the tilt is in a moderate state. Since there are cases, there is a problem in that it takes time and labor to check the passengers.

  In addition, in a so-called lie flat seat (hereinafter referred to as “L / F”) that can be tilted to a bed state in which the seat posture is inclined, which is currently provided for business class seats, Since movements such as slide and rotation are combined in a complicated manner, there is a problem that it is difficult to determine whether a seated passenger is in an upright state or not.

  Further, such L / F is tilted mainly by electric power, and during the tilting operation, for example, some things such as shoes and pillows placed near the seat device became an obstacle and the tilting operation was prevented. In some cases, an overcurrent is detected, and the tilting operation may be terminated halfway. In such a case, even if a passenger intends to perform a button operation for changing the seat posture to an upright state to make the seat posture an upright state, the seat posture may not actually be in the upright state. .

  With respect to the above problems, the technique described in Patent Document 1 confirms the installation angle of the seat device and cannot be used to determine the state of the seat posture. It is not a means to solve the problem.

  The present invention has been made paying attention to such problems of the conventional technology, and an object of the present invention is to provide an aircraft seat device that can very easily determine whether or not the seat posture is in an upright state. And

The gist of the present invention for achieving the object lies in the invention of the next section.
[1] In the aircraft seat device (1) in which the seat back (10) can tilt,
A back cover (100) for covering the back side of the aircraft seat apparatus body below the back of the seat back (10);
An upper cover (110) that appears and disappears in a gap (50) between the upper part of the back cover (100) and the back of the seat back (10b) in conjunction with the tilting of the seat back (10);
The upper cover (110) emerges from the gap (50) when the seat back (10) is in the most upright state and is visible from the side or the rear of the aircraft seat apparatus body. An aircraft seat apparatus (1) , comprising: a determination means (200) for determining whether or not the seat back (10) is in an upright state .

The present invention operates as follows.
In the aircraft seat apparatus (1) in which the seat back (10) of [ 1 ] can tilt, the back cover (100) covers the back side of the aircraft seat apparatus main body below the back of the seat back (10). The upper cover (110) provided on the upper portion of the back cover (100) is linked with the tilt of the seat back (10), and the gap between the upper portion of the back cover (100) and the back of the seat back (10b). It appears at (50).

  In the upright state where the seat back (10) is most raised, the upper cover (110) emerges from a gap (50) between the upper portion of the back cover (100) and the back of the seat back (10b). It is located so as to close the gap (50). At this time, the upper surface (110a) of the upper cover (110) can be easily seen from the lateral direction or the rear side of the seat back (10).

  On the other hand, in the reclining state in which the seat back (10) is tilted from the upright state, the upper cover (110) is housed in the gap (50) in conjunction with the tilt of the seat back (10). (110a) becomes invisible.

  Since the line (200) is drawn in an easily distinguishable color different from the color of the upper cover (110) on the upper surface (110a), the seat back (10) depends on whether the line (200) can be visually confirmed. ) Is in an upright state or a reclining state. Therefore, it is possible to easily determine whether or not it is in the upright state.

According to an aircraft seat apparatus according to the present invention, when the upright state in which the seat back is most erect, discriminating means provided in the upper cover infested at the gap between the upper and the seat back rear surface of the back cover is an aircraft Since it appears visibly from the side or the rear of the main body of the seat for a vehicle, it can be determined at a glance whether or not the seat posture is in the upright state.

  In addition, since it can be directly visually confirmed by the human eye without using an electrical or electronic device that detects the state of the seat back, erroneous determination due to malfunction or misidentification of the device can be made. There is no end.

  In addition, since it is only necessary to provide a discriminating means that can be seen directly by the human eye, a new device or the like for discriminating whether the seat posture is in the upright state is developed or the design is changed. It is not necessary and costs little.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.

  The aircraft seat apparatus 1 includes a seat member 10 that can be tilted, a movable seat bottom 30 on which a seated person sits, a legrest 40 that can be rotated at the front end of the seat bottom 30, and a displaceable seat constituent member. An armrest 20 is provided. By displacing these seat constituent members, the seat postures made can be changed. These displaceable seat components are electrically displaced by a motor (not shown), but may be manually displaceable.

  The seat back 10 includes a metal seat back frame 310 therein, and the seat bottom 30 is provided on a metal bottom frame 330. A cushion member is attached to the seat back 10 so as to wrap the seat back frame 310, and a cover made of a cloth material or the like is covered thereon. A cushion member is attached to the seat bottom 30 so as to cover the bottom frame 330, and a cover made of a cloth material or the like covers the seating surface and the outer surface.

  The seat back 10 can be tilted toward the back side from a specific position where the seat back 10 cannot rise up and cannot rise up. Further, the seat bottom 30 can be reciprocated forward from a specific position located at the rearmost position. The upper portion of the legrest 40 is connected to a rotation shaft (not shown) disposed below the front end portion of the seat bottom 30, and the legrest 40 is located above the specific position shown in FIG. It can be rotated toward. When these displaceable seat components are each in a specific position, their seat posture is in the upright state with the least tilt. When each of these displaceable seat constituent members is displaced from the specific position, the seat posture changes so as to be tilted more than the upright state, and a so-called reclining state is obtained.

  A back cover 100 that covers the lower part of the back side of the aircraft seat device 1 is provided below the back of the seat back 10. A gap 50 between the upper portion 100a and the seat back rear surface 10b is interlocked with the tilting of the seat back 10 between the upper portion 100a and the seat back rear surface 10b at substantially the same height as the upper portion 100a of the rear cover 100. An upper cover 110 that protrudes and protrudes from is disposed.

  In the aircraft seat device 1, a metal base frame portion (not shown) is attached on a leg portion fixed to a floor surface in the aircraft, and a seat back frame 310 and a bottom frame 330 are attached to the base frame portion. Are concatenated and held.

  A bottom plate 340 is disposed in the base frame portion so as to be positioned on both sides of the bottom frame 330. The bottom plate 340 has a lower portion connected to the frame portion, and can swing slightly around the connecting portion. Both ends of a bottom tube (not shown) are fixed to the pair of bottom plates 340, and a bottom frame 330 is attached to the bottom tubes. Thereby, the bottom frame 330 is attached to the base frame portion. Further, the lower end portion 310 a of the seat back frame 310 is axially connected to the rear end portion 340 a of the bottom plate 340.

  As shown in FIG. 2, a recliner arm 350 is disposed outside each bottom plate 340. As shown in FIGS. 4 and 6, the recliner arm 350 includes an upper part 350 a that extends from the seat back 10 toward the front and downward when attached to the aircraft seat apparatus 1, and an upper end part of the upper part 350 a. Leg portion 350b extending downward from the middle portion from the bottom end to the bottom end portion. A guide hole 351 is formed in the upper part 350a in a gently curved shape from the upper end to the lower end along the direction in which the upper part 350a extends.

  A part (not shown) of the lower portion of the seat back frame 310 is connected to the guide hole 351. When the seat back 10 tilts, a part of the lower part moves along the guide hole 351.

  As shown in FIG. 3, a main plate 360 is disposed outside the recline arm 350. The main plate 360 is attached to a rear tube 400 that constitutes a part of the base frame. As shown in FIGS. 4 and 6, the main plate 360 is axially connected with a connecting portion 352 at an intermediate portion between the upper portion 350 a of the recline arm 350 and the lower end portion of the leg portion 350 b. The lower ends of the leg portions 350 b of the pair of recliner arms 350 are connected by an arm 353. As a result, the pair of recliner arms 350 can rotate integrally around the connecting portion 352. The rotation of the recliner arm 350 is interlocked with the tilting of the seat back 10 as will be described later.

  The upper cover 110 is attached to the upper end of the upper part 350 a of the recliner arm 350. Specifically, one attachment shaft 111 is installed between the upper ends of the upper portions 350a of the pair of recliner arms 350. A pan 112 having a length substantially equal to the axial length of the mounting shaft 111 is fixed to the mounting shaft 111 with a bolt. Further, the upper cover 110 is fixed to the upper surface of the pan 112 with bolts. The upper cover 110 is formed in a plate shape having a length substantially equal to the axial length of the mounting shaft 111. The material of the upper cover 110 may be any material that is hard to some extent, such as metal, synthetic resin, or tree.

  In the center of the upper surface 110 a of the upper cover 110, a linear recess 200 (discriminating means) is formed in the longitudinal direction of the upper cover 110. The concave portion 200 is colored with a color different from the color of the surrounding portion. A back cover 100 is disposed below the back of the seat back 10 so as to cover the recliner arm 350, the main plate 360, and the rear tube 400 so as to cover the back side of the aircraft seat device 1 main body. The back cover 100 is fixed to the main plate 360 and the rear tube 400 with bolts via attachments.

  As for the back cover 100, the upper part 100a and the lower part 100b are curving toward the front. The front edge portions of the back cover 100 swell from the front end portion of the upper portion 100a to the middle portion of the front end portion of the lower portion 100b so as to move away from the back side of the aircraft seat device 1. The front end portion of the upper part 100a is in a position where a gap 50 is formed between the seat 100 and the back surface 10b when the seat back is upright and the seat back 10 is most up. A central portion on the front side of the back cover 100 forms a bulging portion 101 that enters the back side of the aircraft seat apparatus 1 from the lower side of the upper portion 100a to the upper side of the lower portion 100b, opposite to the both edge portions. The material of the back cover 100 may be the same as that of the upper cover 110.

  As described above, when the seat back 10 tilts, the reclin arm 350 rotates in conjunction with the seat back 10. 4 and 5 show the positional relationship among the recliner arm 350, the upper cover 110, and the back cover 100 when the seat back 10 is in the upright state where the seat back 10 is most raised.

  The recliner arm 350 has a lower portion of the leg portion 350b in contact with a part of the main plate 360. From this state, the recliner arm 350 cannot be further rotated toward the rear tube 400. In this state, the lower edge portion 110c of the upper cover 110 is in a position where it slightly enters below the front end portion of the upper portion 100a of the back cover 100. On the other hand, the upper edge portion 110b of the upper cover 110 is in a position substantially in contact with the seat back back surface 10b. Thus, the upper cover 110 closes the gap 50 between the back cover 100 and the seat back back surface 10b.

  6 and 7 show the positional relationship among the recliner arm 350, the upper cover 110, and the back cover 100 when the seat posture is in the reclining state tilted from the upright state. The recliner arm 350 rotates with the tilt of the seat back 10, and the lower portion of the leg portion 350 b is at a position away from a part of the main plate 360. By rotation of the recliner arm 350, most of the upper cover 110 is accommodated so as to enter between the lower portion of the upper end portion 100a of the back cover 100 and the bulging portion 101. In this state, the recess 200 is completely hidden by the back cover 100.

Next, the operation will be described.
When the seat back 10 is tilted from the upright state to the reclining state, a part of the lower portion of the seat back frame 310 moves in the guide hole 351 from the upper end portion toward the lower end portion. Since a part of the lower portion of the seat back frame 310 pushes the recliner arm 350 downward, as shown in FIG. 6, the recliner arm 350 rotates in a direction in which the lower portion of the leg portion 350b is separated from a portion of the main plate 360. . By this rotation, the upper cover 110 is stored so as to enter the gap 50 surrounded by the lower portion of the upper end portion 100a of the rear cover 100, the upper portion of the bulged portion 101, and the seat back rear surface 10b. In this state, the concave portion 200 formed on the upper surface 110a of the upper cover 110 cannot be visually observed.

  On the other hand, when returning from the reclining state to the upright state, the above operation is followed in reverse, and in the upright state, the upper cover 110 emerges from the gap 50 and is in a position to close the gap 50. At this time, as shown in FIG. 1, the concave portion 200 can be seen very easily from the side or the rear of the aircraft seat apparatus 1. Therefore, when it is necessary to keep the seat back 10 in an upright state in which the seat back 10 is not tilted at all, such as when the aircraft takes off and landing or runs on the runway, Whether or not the seat back 10 of the seat device 1 is in the upright state can be confirmed very easily not only from the side of the aircraft seat device 1 but also from the rear.

  In the above description, when the seat back 10 is in the upright state on the upper surface 110a of the upper cover 110 that appears and disappears in the gap 50 between the back cover 100 and the seat back back surface 10b disposed on the back side of the seat back 10. The concave portion 200 that can be seen only is provided, but an object that becomes a mark at a predetermined portion that appears visually when the seat back 10 is in either the upright state or the reclining state instead of the concave portion 200 May be provided.

  As the predetermined portion, for example, there is a part of the side surface portion 10 a of the seat back 10. When the seat back 10 is raised most, it appears above the armrest 20, but when the seat back 10 is tilted, the position lower than the upper part of the armrest 20 and hidden by the armrest 20 is the side portion 10 a of the seat back 10. At the bottom of It is possible to determine whether or not it is an upright state by providing a mark as a mark in this part.

  If this part is a fiber, for example, it may be colored in a different color from other parts. Further, in the case of plastic or the like, it may be colored in a color different from the ground color or a sticker that can be clearly identified may be attached. Thus, it can be easily determined that when this portion is visible, it is in the upright state, and when this portion is not visible, it is in the reclining state. If seats for three people are arranged side by side, whether or not the center seat is in the upright state is compared with the position of the seat back 10 of the seat on the aisle side where the upright state is confirmed. The discrimination can be easily performed.

  In addition, when a mark is provided in a portion that is visible in the reclining state and is not visible in the upright state, the seat back 10 is not in the upright state and the mark is not visible if the mark is visible. It can be determined that it is in an upright state.

  In addition to the above example, a protrusion or the like may be provided at the predetermined portion as described above as a mark or the like for determining whether or not it is in the upright state.

  As described above, according to the aircraft seat device of the present invention, the mark appears when the seat posture is in the upright state and appears hidden in the reclining state. It is possible to reliably determine whether or not it is in a write state. Alternatively, when the seat back is in the upright state, the mark is hidden invisible and appears in the reclining state so that it can be visually confirmed. it can.

  In addition, it is possible to make a visual judgment directly with the human eye without providing a device for detecting the state of the seat back, so that erroneous determination due to malfunction or misidentification of the device may occur. There is no.

  In addition, since it is only necessary to provide a simple discriminating means that can be directly seen by the human eye, a new device for discriminating whether or not the seat back is in the upright state has been developed, or the design has been changed. There is no need to pay any cost and there is almost no cost.
