Description

[Technical Field]

[0001] The present invention relates to a seat divider that separates seats. [Background technology]

[0002] Conventionally, seats installed in the passenger compartments of vehicles such as railway cars and airplanes are generally arranged adjacent to each other on both sides, and partitions have been provided between adjacent seats to ensure the privacy of occupants of each seat. For example, Patent Document 1 discloses a specific seat partition in which a partition is fixed onto the console between adjacent seats.

[0003] The seat divider described in Patent Document 1 cannot be moved from its fixed position, and therefore its size is limited so as not to get in the way, and the range in which it divides the seating space for each seat is also extremely limited. As a seat divider that can solve these problems, for example, Patent Document 2 discloses a movable divider that can be slid forward via a rail from a state where it is stored between seats.

[0004] [Patent Document 1] Design Registration No. 1327054 [Patent Document 1] Patent No. 5721807 Summary of the Invention [Problem to be solved by the invention]

[0005] However, even though the seat divider described in the aforementioned Patent Document 2 is a movable divider, its movement is limited to linear sliding in the front-to-rear direction, and the range of movement is also narrow. Therefore, there is a problem that the occupants of each seat cannot adjust the divider to their desired position depending on the usage situation.

[0006] The present invention was made in response to the problems of the conventional technology described above, and aims to provide a seat divider that can be freely adjusted to a desired position within a wide movable range, is easy to use for occupants, and provides excellent privacy. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, one aspect of the present invention is to provide a method for manufacturing a semiconductor device comprising: In seat dividers that separate seats, The seat cushion comprises an arm supported on a mounting portion between adjacent seats in both sides, and a divider connected to the arm to form a boundary between the seats, a base end of the arm is rotatably supported by the mounting portion, and a tip end of the arm is rotatably connected to the divider; The divider can be adjusted to any position and held in that position by rotating the divider itself and the arms. [Effects of the Invention]

[0008] The seat divider of the present invention allows the divider to be freely adjusted to the desired position within a wide range of movement, making it easy for occupants to use and improving privacy protection. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, a representative embodiment of the present invention will be described with reference to the drawings. 1 to 9 show one embodiment of the present invention. The seat divider 10 according to this embodiment separates seats 1 and includes an arm 20 supported by mounting portions between adjacent seats 1 on both sides, and a divider 30 connected to the arm 20 to form a boundary between the seats 1. The type of seat 1 is not particularly limited, but the following description will be given taking as an example a case where the divider is applied to a two-seater seat installed in the passenger compartment of a railway vehicle.

[0011] <Seat 1 Overview> As shown in Figures 2 to 4, the seat 1 is configured with a pair of seat sections 3, 3 arranged side by side on a rectangular base 2 that is long in both directions, for seating two people, and a backrest 4 is supported at the rear end of each seat section 3 so that it can be raised or lowered individually. The base 2 is fixed to the floor, and the pair of seat sections 3, 3 are attached to the base 2 via a frame or the like. The pair of seat sections 3, 3 are supported on the base 2 via a rotation mechanism so that they can rotate in a substantially horizontal direction. Furthermore, each backrest 4 is supported via a reclining mechanism so that the tilt angle can be adjusted.

[0012] Between the pair of seat sections 3, 3, there is provided a center console 5, the upper surface of which serves as an armrest. The seat partition 10 according to this embodiment is provided on the upper surface of the rear of this center sleeve 5. At both ends of the pair of seat sections 3, 3, there are provided sleeve sections 6, the upper surfaces of which serve as armrests. In the following description, terms indicating directions such as up / down, front / rear, left / right, etc. refer to directions as seen by the seated person, and are used for convenience in explaining the positional relationship of each part of the seat 1. Furthermore, the "both sides" refer to directions perpendicular to the front / rear direction of the seat 1, and are left / right directions as seen by the seated person, but either of the "both sides" is not limited to the "right" or "left."

[0013] <Seating Divider 10> As shown in Figure 1, the seat divider 10 comprises a housing 11 installed on the upper rear surface of the middle sleeve section 5 as an attachment part, an arm 20 supported so as to be rotatable in the front-to-rear direction, and a divider 30 rotatably connected to the tip of the arm 20. The divider 30 is configured so that it can be adjusted to any position and held therein by rotating the divider 30 itself and the arm 20. Note that while the housing 11 corresponds to the "attachment part" of the present invention, the "attachment part" may also include the upper rear surface of the middle sleeve section 5, or alternatively, only the attachment bracket 16 described below may be considered the "attachment part."

[0014] <<Arm 20>> As shown in Figure 5, the housing 11 that supports the arm 20 is formed in the shape of a vertically long box. The bottom wall 12 of the housing 11 is fixed horizontally to the upper rear surface of the middle sleeve portion 5. The top wall 13 of the housing 11 curves downward in an arc shape toward the front wall 14. The top wall 13 is provided with a guide groove 13a that movably guides the arm 20 midway.

[0015] A pair of mounting brackets 16, 16 that directly support the base ends of arms 20 are erected on the bottom wall 12 of the housing 11, facing each other on both sides. Between the upper ends of the mounting brackets 16, the base ends of the arms 20 are rotatably supported via joints 23 (described below) that include horizontal rotation axes extending in both directions. The arms 20 extend upward through guide grooves 13a. Alternatively, the housing 11 may be configured without a bottom wall 12, leaving the bottom open, with the mounting brackets 16 erected directly on the upper rear surface of the middle sleeve section 5.

[0016] The range of rotation of arm 20 around the rotation axis (joint portion 23) is restricted by the upper and lower ends of guide groove 13a, and shaft-shaped first stoppers 17, 18 are also disposed at these positions, spanning between both side walls 15, 15 within housing 11. The lower first stopper 17, together with the lower end of guide groove 13a, determines the downward rotation limit of arm 20, and the upper first stopper 18, together with the upper end of guide groove 13a, determines the upward rotation limit of arm 20.

[0017] 1, the pair of first stoppers 17, 18 are spaced apart from each other in the circumferential direction about the rotation axis, and regulate the rotation range of the base end side of arm 20 passing between them. In other words, the angle formed by each first stopper 17, 18 and the rotation axis (joint portion 23) between them defines the rotation range of the base end side of arm 20, and is set to an acute angle of approximately 75 degrees in FIG. 1, for example.

[0018] The arm 20 is made up of a plurality of segmented arms connected to each other so that they can be bent, and in this embodiment, it includes a first segmented arm 21 rotatably supported on the mounting bracket 16, and a second segmented arm 22 rotatably connected to the first segmented arm 21. The arm 20 is configured so that the first segmented arm 21 extends upward from the housing 11 and rotates in the front-to-rear direction, and the second segmented arm 22 can further bend back and forth. Here, the base end of the first segmented arm 21 corresponds to the base end of the arm 20 as a whole, while the tip end of the second segmented arm 22 corresponds to the tip end of the arm 20 as a whole.

[0019] The base end of the first segmented arm 21 is rotatably supported by the mounting bracket 16 via a joint 23A. The tip of the first segmented arm 21 is rotatably connected to the base end of the second segmented arm 22 via a joint 23B. The tip of the second segmented arm 22 is rotatably connected to the divider 30 via a joint 23C. Each of the joints 23A, 23B, and 23C is equipped with a damper that reduces rotational fluctuations (torque fluctuations) around the rotation axis. When joints 23A, 23B, and 23C are collectively referred to as joints 23.

[0020] The first segmented arm 21 is formed, for example, in the shape of a rod extending linearly, and has circular portions at both ends with a diameter larger than the width at the midpoint to provide joints 23. The material of the first segmented arm 21 is not limited to metal such as aluminum alloy, but may also be a high-strength, lightweight material such as engineering plastic or carbon fiber. The second segmented arm 22 is also configured in the same manner as the first segmented arm 21. Each segmented arm 21, 22 is configured to be bendable by its respective joints 23 on a plane perpendicular to the direction of both sides of the seat 1.

[0021] The joint 23 is equipped with a damper that can hold the rotation axis and the damper at any rotation angle. Here, the damper has a structure that can hold two parts connected around the rotation axis in a semi-fixed state at a predetermined rotation angle relative to each other. Dampers can use, for example, surface friction resistance or a mechanical locking mechanism, but their configurations are common and will not be described here. It is sufficient that the joint 23, regardless of whether it has a damper, is easily rotatable manually and can maintain the rotation angle against the load it supports when no manual external force is applied. Therefore, the joint 23 may be simply connected by screwing together a bolt and nut that form the rotation axis, with a tightening force that is not sufficient to rotate due to its own weight, etc.

[0022] <<Divider 30>> As shown in Figure 5, the divider 30 is formed in the shape of a plate with a predetermined thickness and an internal gap. When viewed from the side, the divider 30 has two side walls 31, 31 of the shape shown in the figure, facing each other across a gap that accommodates the second segment arm 22, and the outer periphery of these walls is surrounded by a peripheral wall portion 32. The material of the divider 30 is not limited to metal such as aluminum alloy, but it is also preferable to use a high-strength, lightweight material such as engineering plastic or carbon fiber. Furthermore, the divider 30 is suitably made of an opaque material that not only physically divides the seating space for each seat 1 but also blocks views.

[0023] The tip of the second segmented arm 22 is rotatably connected to the divider 30 at a position eccentric to the center of gravity of the side wall 31. Here, the tip of the second segmented arm 22 is rotatably connected via the joint 23C described above, and the divider 30 is configured to be rotatable on the plane on which the arm 20 bends. The side including the tip of the second segmented arm 22 is stored between both side walls 31, 31 of the divider 30, and the peripheral wall 32 is provided with a guide groove 32a that movably guides the middle of the second segmented arm 22.

[0024] The divider 30 has the illustrated shape that intersects with the rotation axis (joint 23C) and spreads radially in a side view, and the joint 23C that serves as the rotation center is located approximately in the center closer to the rear edge than the center of gravity in a normal posture. The specific shape of the divider 30 and the position of the rotation center depend on the region (area) suitable for dividing the seating space between the seats 1.

[0025] The rotation range of the divider 30 around the rotation axis (joint portion 23C) is restricted by the upper and lower ends of the guide groove 32a, and shaft-shaped second stoppers 33, 34 are also disposed at these positions, spanning between both side walls 31, 31 within the divider 30. The lower second stopper 33, together with the lower end of the guide groove 32a, determines the counterclockwise rotation limit of the divider 30, and the upper second stopper 34, together with the upper end of the guide groove 32a, determines the clockwise rotation limit of the divider 30.

[0026] 1, the pair of second stoppers 33, 34 are spaced apart from each other in the circumferential direction around the rotation axis, and regulate the rotation range of the tip side of the arm 20 passing between them. In other words, the angle formed by each second stopper 33, 34 and the rotation axis (joint 23) therebetween is the range in which the divider 30 can rotate with respect to the tip of the second segment arm 22, and is set to an obtuse angle of approximately 155 degrees in FIG. 1, for example.

[0027] <Function of Seat Divider 10> Next, the operation of the seat partition 10 according to this embodiment will be described. 1, the basic movement of the seat divider 10 is as follows: first, of the arm 20, the first segment arm 21, which is proximal to the housing 11, which is its mounting portion, can be rotated by a joint portion 23A relative to the mounting bracket 16 and held at any rotation angle. The range within which the first segment arm 21 can rotate is restricted by a pair of first stoppers 17, 18.

[0028] Furthermore, the second segment arm 22 of the arm 20, which is distal to the housing 11, can also be rotated relative to the tip of the first segment arm 21 by the joint 23B and held at any rotation angle. In this way, the arm 20 can be bent at any rotation angle between the first segment arm 21 and the second segment arm 22. The bendable range of the first segment arm 21 and the second segment arm 22 is indirectly restricted by a portion of the peripheral wall 32 of the divider 30 abutting against the upper surface of the middle sleeve portion 5.

[0029] Furthermore, the divider 30 can be rotated relative to the tip of the second segment arm 22 by the joint 23C and maintained at any rotation angle. The range within which the divider 30 can rotate is restricted by a pair of second stoppers 33, 34. The range within which the divider 30 can rotate is also restricted by a portion of the peripheral wall 32 of the divider 30 abutting against the upper surface of the middle sleeve portion 5.

[0030] The height position, front-rear position, and rotation angle of the divider 30 can be adjusted over a wide range and in a variety of ways by rotating or bending the arm 20 in this way and by rotating the divider 30 relative to the arm 20. Moreover, each joint part 23 equipped with a damper can be easily moved manually and can be maintained in that state unless a manual external force is applied, making it easy for the seated person to use.

[0031] This allows the divider 30 to be easily held in a comfortable position desired by the seated person. Therefore, a comfortable seating space can be provided where the seated person does not have to be bothered by the seated person in the adjacent seat, thereby improving privacy protection. Furthermore, when a separation by the divider 30 is not particularly required, the divider 30 can be stored in a position along the space between the backrests 4, as shown in FIG. 6, which will be described later. In such a case, there is no need to provide a dedicated storage space in the seat itself, as in the case of conventional movable dividers.

[0032] The seat divider 10 according to this embodiment can be constructed more simply than, for example, the sliding type described in the aforementioned Patent Document 2, and therefore the number of parts and assembly steps can be reduced, thereby reducing costs. Moreover, as shown in Fig. 5, the seat divider 10 is constructed as a unit including the housing 11, which is its mounting location, and therefore is easy to handle and can be easily retrofitted to the middle sleeve section 5 between the seats 1 without requiring any special modifications to the existing seats 1.

[0033] Next, a specific example of adjusting the position of the divider 30 will be described. 6 shows the initial position of the divider 30 when no separation by the divider 30 is particularly required. When the backrests 4 of each seat 1 are in an upright position, the divider 30 in this position is stored so as to fit between the backrests 4 without protruding too far forward. At this time, the first segmented arm 21 has rotated rearward to the furthest extent and is in contact with the first stopper 18. The second segmented arm 22 has rotated so as to bend slightly forward beyond the tip of the first segmented arm 21. Furthermore, the divider 30 is held at a rotation angle at which the second segmented arm 22 is in contact with the second stopper 33.

[0034] In Figure 7, the divider 30 is positioned so as to block the area from approximately the middle in the height direction of the backrest 4 to approximately the middle in the front-to-rear direction of the middle sleeve portion 5. In order to achieve this position of the divider 30, the first segmented arm 21 is not moved from the state shown in Figure 6 above, and the second segmented arm 22 is bent significantly downward from the tip of the first segmented arm 21. Furthermore, the divider 30 is rotated clockwise from the state shown in Figure 6 above, and one end of its peripheral wall portion 32 is brought into contact with the upper surface of the middle sleeve portion 5.

[0035] In Figure 8, the divider 30 is positioned so as to block the area from approximately the middle of the backrest 4 in the height direction to the front of the middle sleeve portion 5 in the front-to-rear direction. In other words, the position of the divider 30 is moved farther from the backrest 4 than in the state shown in Figure 7 above. At this time, the first segmented arm 21 has rotated most forward and is in contact with the first stopper 17. In addition, the second segmented arm 22 has rotated so as to bend at an approximately right angle forward from the tip of the first segmented arm 21. Furthermore, the second segmented arm 22 of the divider 30 is in contact with the second stopper 34, and one end of the peripheral wall portion 32 is in contact with the upper surface of the middle sleeve portion 5.

[0036] In Figure 9, the divider 30 is positioned above approximately the middle in the height direction of the backrest 4 so as to block the seating space in front of it. In other words, the position of the divider 30 is moved farther from the backrest 4 than in the state shown in Figure 6 above. At this time, the first segmented arm 21 is held between a pair of first stoppers 17, 18, and the second segmented arm 22 is rotated so as to bend slightly forward from the tip of the first segmented arm 21. Furthermore, the divider 30 is held at a rotation angle that allows the second segmented arm 22 to pass between a pair of second stoppers 33, 34.

[0037] <Configuration and effects of the present invention> Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments. The present invention derived from the above-described embodiments will be described below.

[0038] First, the present invention provides a seat partition 10 for separating seats 1, The seat cushion comprises an arm 20 supported on a mounting portion between adjacent seats 1 on both sides, and a divider 30 connected to the arm 20 to form a boundary between the seats 1, A base end of the arm 20 is rotatably supported by the mounting portion, and a tip end of the arm 20 is rotatably connected to the divider 30, The divider 30 is characterized in that it can be adjusted to any position and held in that state by rotating the divider 30 itself and the arm 20 .

[0039] According to this seat divider 10, the height position, front-rear position, and rotation angle of the divider 30 can be adjusted over a wide range and in a variety of ways. Therefore, the divider 30 can be held in a comfortable position desired by the seat occupant, which is convenient for the seat occupant and improves privacy protection.

[0040] In addition, in the present invention, the arm 20 is characterized by comprising a plurality of segmented arms 21, 22 connected to each other so as to be able to bend.

[0041] Such an arm 20 can be bent at the connection points between the segmented arms 21, 22 from the segmented arm 21 proximal to the attachment portion to the segmented arm 22 distal to the attachment portion. Therefore, the combined action of not only rotating the entire arm 20 but also bending the arm 20 itself allows the position of the divider 30 to be adjusted over a wider range.

[0042] In the present invention, the base end of the arm 20 is rotatably supported via a joint 23A provided with a damper that can hold the arm at any rotation angle at the mounting portion, The tip of the arm 20 is rotatably connected to the divider 30 via a joint 23C equipped with a damper that can hold the arm at any rotation angle, The arm 20 is characterized in that the segmented arms 21 and 22 are rotatably connected to each other via a joint 23B equipped with a damper that can hold the arm 20 at any rotation angle.

[0043] With this configuration, the base end of the arm 20 can be easily maintained at a desired rotation angle by the dampers provided in the joints 23A, 23B, and 23C. In addition, the bending angle between the segmented arms 21 and 22 can also be easily maintained, and further, the divider 30 can also be easily maintained at a desired rotation angle.

[0044] Furthermore, the present invention is characterized in that the arm 20 and the divider 30 are rotatable along a vertical plane perpendicular to the direction on both sides in which the seats 1 are lined up. This configuration allows the position of the divider 30 to be adjusted on the vertical plane that best defines the boundaries between the seats 1.

[0045] In the present invention, the mounting portion is provided with first stoppers 17 and 18 that restrict the range in which the base end of the arm 20 can rotate, The divider 30 is provided with second stoppers 33 and 34 that restrict the range of rotation of the arm 20 relative to the tip end thereof, The first stoppers 17 and 18 are arranged in a pair at the mounting portion with the rotation center of the arm 20 between them, and each abut on the middle of the arm 20. The second stoppers 33 and 34 are arranged as a pair on the divider 30 with the center of rotation of the arm 20 between them, and are characterized in that they abut midway on the arm 20, respectively.

[0046] Such first stoppers 17, 18 can reliably and easily restrict the range of rotation of arm 20 relative to the mounting portion with a simple configuration. Also, the second stoppers 33, 34 can reliably and easily restrict the range of rotation of divider 30 relative to arm 20 with a simple configuration.

[0047] In addition, in the present invention, the angle formed by the pair of first stoppers 17, 18 and the rotation center of the arm 20 therebetween is set to an acute angle, The angle formed by the pair of second stoppers 33, 34 and the rotation center of the divider 30 therebetween is set to an obtuse angle.

[0048] In this way, by setting the angle formed by the pair of first stoppers 17, 18 and the center of rotation of arm 20 to an acute angle, it is possible to prevent arm 20 from rotating excessively to a position where it is no longer useful, and it is possible to firmly hold arm 20 at the position where it abuts against first stoppers 17, 18.

[0049] Furthermore, by setting the angle formed by the pair of second stoppers 33, 34 and the center of rotation of the divider 30 to an obtuse angle, the range of rotation of the divider 30 can be secured relatively wide, and the divider 30 can be firmly held at the position where the arm 20 abuts the second stoppers 33, 34.

[0050] Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions that do not deviate from the gist of the present invention are also included in the present invention. For example, while the above embodiments have been described using a two-seater seat 1 for a railway vehicle as an example, the seat device may also be configured as a three-seater or four-seater seat. Furthermore, the seat 1 is not limited to seats for railway vehicles, and may also be applied to seats for other vehicles such as airplanes, automobiles, and ships.

[0051] Furthermore, the specific shapes of the entire arm 20 and each of the segmented arms 21, 22 are not limited to those extending linearly as shown in the drawings, but are design matters that can be selected as appropriate. Furthermore, the arm 20 is not limited to a configuration in which multiple segmented arms are connected in series, but may be configured so that only one arm rotates. In such a case, the range in which the position of the divider 30 at the tip of the arm can be adjusted is limited to one circular orbit, but the configuration of the entire arm can be simplified. In addition, the arm can also be configured to bend freely at any position, for example. [Industrial Applicability]

[0052] The present invention can be widely applied to seats for vehicles installed in the passenger compartments of railway cars, airplanes, automobiles, ships, etc., as well as to viewing chairs installed in movie theaters, theatres, etc. [Explanation of symbols]
