DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting seat / chair which is fixedly used on a floor in a theater, a movie theater, a meeting place or the like (these are collectively referred to as a chair for a theater hall in this specification). . More specifically, the present invention relates to a theater hall chair in which the front-rear spacing of chairs (the spacing between the front part of the front seat and the front part of the rear seat, which becomes the passage of the customer seat) is variable.

[0002]

2. Description of the Related Art In the case of chairs for theater halls installed in movie theaters, theaters, halls, and the like, the layout is restricted by architectural regulations and fire prevention regulations. For example, the space between the front and rear chairs serving as the passenger seat passage 105 is required to provide a minimum horizontal distance (for example, about 350 mm) because it is necessary to secure a sufficient space as an evacuation passage in order to make it easy for spectators to come and go and to prepare for emergency. ) Must be taken.
On the other hand, when laying out the chairs for theater halls, it is desirable to use the space as effectively as possible to increase the number of chairs and the number of spectators that can be accommodated.

As a chair for a theater hall which satisfies such a demand, a chair 101 capable of flipping up a seat 102 as shown in FIG. 9 is conventionally used. In the case of such a flip-up type seat, the seat 1 to be flipped up
Numeral 02 is provided so that the back of the seat fits inside the armrest 104 as shown by a virtual line. Therefore, the distance L between the chairs is set at the top of the backrest 103 of the front seat (the last part of the front seat).
And the front end of the armrest 104 of the rear seat (the frontmost part of the rear seat) that projects most forward when the seat 102 is flipped up.

[0004]

However, in the flip-up theater hall chair 101, it is possible to adopt a layout that allows as many chairs as possible to be installed while securing the minimum distance L between the chairs. The seat 102 whose armrest 104 has jumped up because of the highest priority
The seat is slightly longer than the seat back. Therefore, the length of the armrest 1 is larger than the length of the seat 102.
04 is not long enough and elderly people
There is a problem that the operation may not be easy to stand or sit using the 04.

Further, in the case of the chair 101 which does not have the reclining function of the backrest 103, the angle of the backrest is fixed, and the chair is not tilted sufficiently to secure the distance L between the chairs. You can't take a comfortable posture, and you may get tired if you sit for a long time.

Accordingly, the present invention provides a theater hall in which the depth of the chair itself is shortened while securing a predetermined chair front-back distance, the degree of freedom in layout is improved, and a sufficient length of armrests can be provided. It is intended to provide a chair for use.

[0007]

According to the first aspect of the present invention, a chair for a theater hall fixed to a floor of a theater hall or the like is provided between a sitting position and a standing position by a seat. A seat supported to be tiltable,
A backrest that is tiltably supported by the seat support, and a connecting unit that connects the backrest to the seat support, wherein the backrest includes a seat on which the seat is seated. It tilts backward in conjunction with the tilting to the position direction, maximizes the opening angle θ with the seat when located in the sitting position, and tilts forward in conjunction with the seat tilting in the standing position direction When the user stands up and the seat is in the standing position, the opening angle θ is minimized.

In this case, since the seat is constantly urged in the direction of the standing position by the urging means, when the occupant is not present, the seat is urged in the direction of the standing position and held in the standing position. . Since the backrest is provided so as to interlock with this seat, it tilts forward most when no occupant is present to minimize the opening angle θ. Therefore, at this time, the dimension of the chair in the depth direction is minimized, and the front-back distance between the chairs is maximized. On the other hand, at the time of sitting, the backrest tilts rearward as the seat is pushed down to the seating position by the seated person, and the opening angle θ is maximized at the seating position. Therefore, the fall angle of the backrest can be sufficiently obtained, and the seated person can take a comfortable posture.

In the invention according to claim 2, the connecting means in the theater hall chair according to claim 1 is a link rotatably connected to the seat and the backrest. in this case,
The tilt angle of the backrest with respect to the tilt angle of the seat is appropriately set by changing the length and the connection position of the link.
Also, the backrest smoothly interlocks with the seat.

In the chair for a theater hall according to the third aspect, when the seat is in a standing position, a fulcrum connecting the link and the seat, a fulcrum connecting the link and the backrest, and a front side which is the tilting center of the seat. The connecting pins are arranged substantially in a straight line. Therefore, even if a person in the back seat stands up or a person passing through the passage on the rear seat side puts a hand or the like on the backrest in the standing position and applies force in the front-rear direction, it forms a dead center. Link does not move.

In a theater hall chair according to a fourth aspect of the present invention, the seat support or the backrest is provided with a stopper that abuts on a locking member that tilts with the seat to limit the tilting range. Therefore, the movement of the seat and the backrest can be maintained at a predetermined position, and a suitable sitting posture and a standing position can be set.

According to a fifth aspect of the present invention, the connecting means in the theater hall chair according to the first aspect comprises a long hole provided in the backrest and a seat which is slidably and rotatably engaged with the long hole. Has been part. Therefore, when the seat tilts, the engaging portion of the seat slides against the long hole and abuts, and the backrest also tilts in conjunction.

According to a sixth aspect of the present invention, in the theater hall chair according to the first aspect, the connecting means is a pin for rotatably connecting the seat and the backrest, and the seat is provided in an elongated hole provided in the seat. The projection provided on the receiver is engaged, so that the seat can slide and swing with respect to the seat receiver. Therefore, when the seat slides and swings forward with respect to the seat receiver, the connection point with the backrest also moves forward, and the backrest also tilts backward in conjunction with the backrest.

According to a seventh aspect of the present invention, there is provided a chair for a theater hall, comprising an armrest extending forward to a position near a front end of a seat located at a seating position. Since the backrest tilts forward and stands upright when in the standing position, the armrest can be set so as to project sufficiently forward in the chair installation space, securing passage space. However, it is possible to easily perform the operation of standing and sitting on the chair.

In the chair for a theater hall according to the present invention, a luggage storage is provided below the seat. Therefore, in addition to the luggage storage being able to be used for storing the luggage of the occupant, the space for the feet can be sufficiently secured by interlocking with the seat.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below in detail based on an example of an embodiment shown in the drawings.

1 to 4 show an embodiment of a chair for a theater hall according to the present invention. The chair 1 for a theater hall is tiltably supported by a seat support 6 and changes its posture between a sitting position shown by a solid line in FIG. 1 and a standing position shown by a solid line in FIG. The seat 2 is provided with a backrest 3 and a fixed armrest 4 which are connected to the seat receiver 2 by a connecting means 30 and tilt together with the seat 2.

The seat 6 is mounted and fixed directly on a leg 5 fixed to the floor of a theater, a movie theater, a meeting place, or the like, or on a girder material (not shown) stretched over the leg 5. In the theater hall chair 1 according to the present embodiment, the chair 1 is mounted on the legs 5 and then fixed by bolts or the like using fasteners. The seat 6 is formed of four side plates and one bottom plate, and both side walls 6 which are also support plates for the seat 2 and the like.
a and 6a are formed in a U-shape or a V-shape as shown in FIGS. The side walls 6a, 6a support the seat support plate 9 and the back support rod 8 in a tiltable manner with a front connection pin 10 provided on the front side and a rear connection pin 11 provided on the rear side. The front connection pin 10 and the rear connection pin 11 are formed by holes provided at symmetrical positions of the side walls 6a, 6a and support rods passing through the holes, respectively. , 6a may be formed with inward projections, and these projections may be engaged with holes or depressions provided in the seat support plate 9 and the back support rod 8. A fastening means 13 such as a bolt is attached to the front wall portion 6b, and an urging means for urging the seat support plate 9 in a direction to flip up the seat 2 to the fastening means 13, for example, one end of a coil spring 12 is fixed. Have been. Here, in order to prevent the fastening means 13 from projecting from the surface of the front wall portion 6b, the front wall portion 6b is provided with a recess 14 that is recessed toward the rear side.

The seat 2 supported by the front connecting pin 10 is constituted by a seat support plate 9 and a seat 15. In this case, the seat 15 is detachably provided so as to be detachable from the seat support plate 9, and can be slid along the seat support plate 9. The seat support plate 9 is provided with a biasing means 12 provided on a support rod constituting a seat support point.
The seat 2 is always urged in the standing position direction so that the seat 2 naturally jumps up to the standing position and posture when there is no occupant. The seat 2 is provided such that the seat back 2b fits inside the armrest 4 at the standing position.

The seat support plate 9 has a locking member 1 for restricting the tilting range of the seat 2 and obtaining an appropriate sitting posture at the time of sitting.
7 are integrally formed so as to protrude rearward,
It tilts around the front connection pin 10 with the seat 2.
As shown in FIG. 4, a pair of locking members 17 in the present embodiment are provided symmetrically left and right, but the present invention is not limited to this. For example, one locking member 17 may be provided at either one or at the center. However, in order to reduce the torsion of the seat support plate 9, it is preferable that the locking members 17 are symmetrical or disposed at one central position. Further, the seat receiver 6 is provided with stoppers 18 and 19 which contact the locking member 17 and limit the tilting range of the seat support plate 9. One stopper 18
As shown in FIG. 4, the seat is formed of a horizontal plate attached between both side walls 6a, 6a of the seat support 6, and as shown in FIG. Keep the sitting position of 2. In this case, the stopper 18 is fixed to the seat receiver 6 so as not to change its position irrespective of the tilt of the seat 2, but the backrest 3 or the backrest 3
May be provided on the back support rod 8 that supports the lock member 17 so as to protrude into the tilting range of the locking member 17. Further, the other stopper 19 is provided inside the seat 6 and protrudes to a position where it engages with the lower surface of the locking member 17 so as to maintain the posture of the seat 2 in the standing position. This stopper 1
9 is formed by attaching a bent plate-like member as shown in FIG. Since both of these stoppers 18 and 19 determine the standing posture and the sitting posture of the seat according to the engagement position with the locking member 17, it goes without saying that each of them is provided at an appropriate position. On the engagement surfaces of the locking member 17 and the stoppers 18 and 19, there is provided a buffer member 20 made of a rubber material or the like that buffers an impact at the time of engagement. This cushioning member 20
For example, the stopper 18 is formed in a plate shape, and the stopper 19 is formed in a semi-cylindrical shape having a high elasticity in order to suppress an impact sound, but the shape is not particularly limited thereto.

On the rear side of the seat support plate 9, the link 7 used as the connecting means 30 is rotatably attached to the tiltable seat support plate 9. The link 7 is formed by a pair of plate-shaped or rod-shaped members provided symmetrically between the back side of the seat support plate 9 and the lower end 8a of the back support rod 8 so that the seat 2 and the backrest 3 are linked. Are linked. The link 7 is provided such that the fulcrums 7a and 7b at both ends of the link and the front connection pin 10 are positioned substantially in a straight line in the standing position shown in FIG. In the theater hall chair 1 provided in this manner, since the seat 2 constitutes a dead point at the standing position where the seat 2 jumps up, even if a force in the front-rear direction is applied to the backrest 3, the link 7 stretches and the seat 2 moves. Nothing. Therefore, even if the backrest 3 is unexpectedly put on the hand, the passage in front of the chair is suddenly narrowed due to the fall of the seat 2 or the foot of the person on whom the seat 2 stands is hit. It can prevent unexpected situations from occurring. Moreover, if the seat 2 of the theater hall chair 1 in the standing position is pushed down so as to fall forward,
The seat 2 and the backrest 3 can be moved. In addition,
From the viewpoint of preventing the backrest 3 from tilting from the rear in this manner, the fulcrums 7a and 7b of the link 7 and the front connection pin 10 may be arranged in a substantially straight line in the standing position state. Of course, it may be formed so as to be arranged in a V shape in FIG.

The backrest 3, which is tiltably supported by the rear connection pin 11 of the seat receiver 6, has a
The seat 15 is detachably provided in the same manner as the seat 15 and can be removed while sliding upward along the back support rod 8. The lower end 8a of the back support rod 8 is formed below the rear connection pin 11 so as to be bent forward once and then further extended, and is rotatably connected to the link 7 at a support point 7b at the tip. Have been. Since the back support rod 8 is connected to the seat support plate 9 via the link 7 in this manner, a slight oblique displacement in conjunction with the forward and backward tilting of the seat 2 causes the link 7 to move from the seat 2 side. When it is given to the lower end 8a of the back support rod 8 via this, it is provided so that its posture can be changed within a predetermined range. That is, when the seat 2 is tilted from the standing position to the sitting position as shown in FIG. 1, the link 7 is lifted upward, and in conjunction with this, the lower end 8a of the back support rod 8 is pulled upward to move upward. The portion of the back support rod 8 above the rear connection pin 11 is gradually tilted rearward with the rear connection pin 11 as a center. The backrest 3 tilting in this manner widens the opening angle θ between the backrest 3 and the seat 2 to realize a comfortable sitting posture. On the other hand, as shown in FIG. 2, when the seat 2 tilts from the sitting position to the standing position in the opposite direction, the backrest 3 stands and narrows the opening angle θ to secure a sufficient space between the chairs when not seated and to provide a passage space. Spread out.

In the chair 1 for a theater hall according to the present embodiment, the seat support plate 9 and the back support rod 8 are formed of a steel plate frame, and the seat 2 and the backrest are provided for each frame as described above. 3 are provided detachably. Therefore, the chair can be easily transported, and can be easily installed in a theater or a hall. To attach the seat 2 and the backrest 3 to each frame,
For example, a fastening means composed of a bolt or a nut may be used, or an engaging claw for facilitating attachment and detachment may be used. Note that the seat 2 itself is not particularly limited in its structure, material, and the like, and can be implemented even if it has the same structure as a conventional seat.

Armrests 4 are provided on both sides of the seat 2. This armrest 4 is attached to a girder material, for example.
The seat 2 is fixedly provided at a fixed position irrespective of tilting. In a conventional chair in which the backrest 3 is fixedly mounted diagonally, the armrest 4 is obtained by subtracting the length occupied by the backrest 3 from the depth of the chair and moving the armrest 4 in the front-rear direction. The length of the armrest is determined. However, in the theater hall chair 1 according to the present embodiment, since the backrest 3 is provided so as to be swingable, the maximum armrest length while securing the minimum chair back-and-forth distance is ensured. Can be provided. That is, since the length of the armrest 4 can be set to the full depth of the space given to each of the theater hall chairs 1,..., The distal end of the seat 2 in which the armrest 4 is located at the seating position It can be formed so as to extend forward to the vicinity of 2a, and it is possible to easily perform the operation of standing and sitting on the chair 1 for the theater hall while securing a passage space.

According to the chair 1 for a theater hall constructed as described above, while having the armrest 4 having a sufficient length, a sufficient aisle space is secured for the attendees to come and go as follows, and comfort is ensured when sitting. Posture can be taken. That is, when the seat 2 is tilted forward, the back support rod 8
Tilts backward to widen the opening angle θ with the seat 2. The tilting of the seat 2 is stopped by the engagement of the locking member 17 with the stopper 18, and the seat 2 is fixed at that position, that is, the seating position. Here, in the chair 1 for a theater hall, the armrest 4 is formed so as to sufficiently project forward by securing a sufficient length of the armrest 4, for example, so that the elderly can sit or stand. The operation is easy. Further, when there is no occupant, the seat 2 and the backrest 3 are returned to the standing position by the urging means 12 and the opening angle θ is minimized, so that the chair front-back distance is automatically maximized, and the passage space is sufficiently secured. You.

Next, FIG. 5 shows another embodiment. In this case, the seat 2 and the backrest 3 are tiltably supported by the fixed seat 6 and connected to each other by the connecting means 30 so as to interlock with each other. In the present embodiment, the link 7 is not swung directly by the seat support plate 9, but is swung via the elastic member 21.

The elastic member 21 is composed of, for example, a compression coil spring or a gas spring. One end of the elastic member 21 rotates at a fulcrum 22 provided at the lower portion of the seat 2 and the other end rotates at a fulcrum 23 provided at the seat 6. Mounted as possible. While the distance between the fulcrums 22 and 23 changes as shown in FIG. 5 when the seat 2 tilts around the front connecting pin 10, the telescopic member 21 between the fulcrums 22 and 23 expands and contracts as appropriate. This change can be followed.
In the vicinity of the fulcrum 23 of the elastic member 21, another fulcrum 24 which swings together with the elastic member 21 is formed by, for example, an L-shaped member. Since one end of the link 7 is further rotatably connected to the fulcrum 24, the fulcrum 24 and the fulcrum 7a are provided at the same position. The other end 7b of the link 7 is rotatably connected to a lower end 8a of a back support rod 8 attached to the seat receiver 6 so as to be tiltable. Therefore, by tilting the seat 2, the telescopic member 21 can be swung while expanding and contracting, and the link 7 can be linked to tilt the backrest 3.

Although not shown here, the locking member and the stopper for limiting the tilting range of the seat 2 and the like are, of course, provided at appropriate positions on the seat receiver 6 and the like. Further, when the elastic member 21 is constituted only by a simple sliding mechanism, an urging means for constantly urging the seat 2 in the standing position direction is also provided separately, though not shown, as in the above-described embodiment. . Further, in the chair 1 for a theater hall in the present embodiment, the fulcrum 23 is provided so as to be substantially located on a straight line connecting the fulcrums 7a and 7b of the link 7 in the standing position, so that only the backrest 3 is provided. Even if a rearward force is applied, the link 7 is not hooked and tilted. Therefore, even if the backrest 3 in the standing position is unexpectedly put on the hand, the seat 2 does not suddenly fall forward.

Next, FIG. 6 shows a third embodiment of the present invention. Also in this theater hall chair 1, the seat 2 and the backrest 3 are supported on a fixed seat 6 so as to be tiltable, and are connected so as to be interlocked. However, in this embodiment, the back support rod 8 and the seat support plate 9 are directly engaged without providing the link 7 or the like between the seat 2 and the backrest 3. Specifically, the rear connecting pin 1 of the back support rod 8
The connecting means 30 is formed by providing a long hole 31 in a portion lower than the first hole 1 and slidably engaging a tip portion 32a provided so as to further project from a lever 32 projecting from the seat 2 in the long hole 31. I am trying to do it. In this case, when the seat 2 is tilted from the standing position shown to the seating position, the distal end portion 32a of the lever 32 becomes the long hole 31 of the back support rod 8.
It slides inside and moves upward. Since the back support rod 8 is gradually pushed upward by the lever 32, the backrest 3 tilts rearward about the rear connection pin 11. Accordingly, the seat 2 and the backrest 3 are tilted forward and backward while interlocking with each other, and the opening angle θ therebetween is gradually widened. When the seat 2 tilts to the seating position, the distal end portion 32a comes into contact with the stroke end of the elongated hole 31 and further tilting is restricted, so that the seat 2 and the backrest 3 are fixed at the seating position. Further, since the moving range of the distal end portion 32a is also limited by the lower stroke end of the long hole 31, in the present embodiment, by appropriately forming the stroke length of the long hole 31, the long hole 31 and the lever 32 Can also be used as a locking member. The seat 2 is provided with a biasing means (not shown) so that the seat 2 returns to the standing position. Therefore, when the seated person stands up or there is no luggage or the like on the seat 2, the seat 2 and the backrest 3 are automatically turned on. It is provided to return to the standing position and widen the passage space.

The chair 1 for a theater hall in the present embodiment.
In the standing position, even if a force in the front-rear direction is applied to the backrest 3, the distal end portion 32 a of the lever 32 is caught by the lower stroke end in the elongated hole 31, so that the backrest 3 does not tilt. . Therefore, it is possible to prevent the width of the passage in front of the chair from suddenly narrowing, or to prevent the seat 2 from hitting the feet of a standing person. In addition, similarly to the above-described embodiments, the seat 2 can be moved and tilted.

FIG. 7 shows a fourth embodiment of the present invention. Also in this embodiment, the seat 2 and the backrest 3 are connected without the link 7 as in the third embodiment. However, here, the seat 2 and the backrest 3 are connected by a connecting means 30 such as a pin so as to be rotatable only (do not slide), and the seat 2 has an elongated hole (or groove) 41 at its lower part. A lever 42 is provided, and is engaged with the projection 43 of the seat receiver 6 so as to be rotatable and slidable with respect to the seat receiver 6. Accordingly, the seat 2 can be tilted while sliding forward from the standing position, and the backrest 3 is tilted rearward about the rear connection pin 11 as the seat 2 moves. That is, in this case, when the seat 2 is tilted from the standing position shown to the seating position, and a downward load is applied to the front end thereof, the long hole 41 slides on the projection 43 while swinging. Move forward. At this time, the backrest 3 tilts rearward about the rear connecting pin 11 as the lower end 8a of the back support rod 8 is gradually pushed upward by the lever 42. When the seat 2 tilts to the seating position, the projection 43
Of the seat 2 and the backrest 3 are restricted. In addition, the slot 6 is provided with a long hole,
The same movement can be performed by engaging a projection provided on the seat 2 with the elongated hole. Also,
Also in the present embodiment, the seat 2 is urged in a direction to return to the standing position by an urging means (not shown), and is returned to the original standing position when there is no load such as when the occupant stands up.

The above embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited thereto, and various modifications can be made without departing from the gist of the present invention. For example, in each of the above-described embodiments, the seat 2 and the backrest 3 are separated at the corner where they intersect,
The present invention is not particularly limited to this, and a part of the backrest 3 and the seat 2 may be integrated so that a corner portion forms a part of the seat 2. In this case, since the object that has fallen on the seat 2 does not fall further on the floor from the gap between the seat 2 and the backrest 3, there is little fear of loss. Also, the rear connecting pin 1
By integrating the seat 2 and the backrest 3 up to 1, the back of the clothes does not slip out even when the backrest 3 is tilted.

In the above-described embodiment, the backrest 3 is always provided so as to interlock with the seat 2. However, the present invention is not limited to this, and the range in which the backrest 3 tilts while the seat 2 tilts is provided. And a range that does not tilt may be partially provided. For example, in the first embodiment, a portion of the seat support plate 9 from the front connection pin 10 to the fulcrum 7a is cranked,
If the portion from the rear connecting pin 11 to the fulcrum 7b of the back support rod 8 can be considered as a lever, it can be said that the crank, the lever, and the link 7 form a part of the lever crank mechanism.
In this case, since the swing amount becomes small near the thought point of the crank, the backrest 3 is prevented from tilting by appropriately changing the length of each link 7, or the range where the tilt amount is small is partially changed. Can be provided.
Further, in the third embodiment shown in FIG.
Is formed in a shape that draws an arc centered on the front connection pin 10, so that an idle running section in which the backrest 3 does not tilt even when the tip portion 32a of the lever 32 swings can be provided. As described above, even if the seat 2 and the backrest 3 are provided with a range in which they can move independently of each other, this does not hinder a sufficient length of the armrest 4 or a sufficient space for the passage. Therefore, similarly to the above-described embodiment,
It is possible to increase the degree of freedom of the movement of the seat 2 and the backrest 3 while ensuring a sufficient passage space or the like.

Further, as shown in FIG. 8, a luggage storage 51 interlocked with the seat 2 may be provided below each seat 2 in each of the above-described embodiments. In this case, the luggage holder 51 is made of, for example, a mesh formed in a rectangular frame in a stitch shape, and is convenient for the occupant to place baggage and a coat. In the case of the luggage holder 51, a certain space is secured between the seat 2 and the seat back 2b when the seat 2 is in the seating position, while when the seat 2 is tilted together with the seat 2, the seat is provided to tilt closer to the seat back 2b. Therefore, it does not become an obstacle even in the standing position state.

[0035]

As is apparent from the above description, in the theater hall chair according to the first aspect of the present invention, the backrest tilts rearward in conjunction with the tilting of the seat in the seating position direction.
When the seat is in the seating position, the opening angle θ with the seat is maximized, and the seat is tilted forward to stand in conjunction with the tilting of the seat in the standing position direction, and the opening angle θ when the seat is in the standing position state. Therefore, it is possible to secure a sufficient passage space when no occupant is present, and to provide the occupant with a comfortable sitting posture. Therefore, a sufficient passage space can be secured even if the chairs are installed in the depth direction at a narrow interval, so that a layout with an increased number of seats is possible, and the audience space in theaters and halls can be more effectively utilized. become.

In the chair for a theater hall according to the second aspect of the present invention, since the connecting means is a link rotatably connected to the seat and the backrest, the seat is tilted by changing the length of the link. The tilt angle of the backrest with respect to the angle can be appropriately set, and a comfortable sitting posture can be obtained. Also, the backrest can be smoothly linked to the seat.

In the chair for a theater hall according to the third aspect of the present invention, when the seat is in the standing position, the fulcrum connecting the link and the seat, the fulcrum connecting the link and the backrest, and the tilting center of the seat. Since a certain front connection pin is arranged substantially on a straight line, the link does not stretch and move even when a force in the front-back direction is applied to the backrest in the standing position. Therefore, when the hand rests on the backrest, it is possible to prevent the seat from falling in conjunction with the seat and abruptly narrowing the passage in front of the chair or hitting the feet of a standing person. Moreover, if the seat is pushed down so as to rotate forward, the backrest can also be tilted at the same time.

In the chair for a theater hall according to the fourth aspect of the present invention, the seat support or the backrest is provided with a stopper that abuts against the locking member that tilts together with the seat and limits the tilting range thereof. The posture and the standing position can be set.

According to the fifth aspect of the present invention, since the connecting means is a long hole provided in the backrest and a part of the seat slidably and rotatably engaged with the long hole, the seat is provided. When tilting the backrest, the backrest can also be tilted.

According to the sixth aspect of the present invention, the connecting means is a pin for rotatably connecting the seat and the backrest, and a projection provided on the seat is engaged with an elongated hole provided on the seat.
