Description

  The present invention relates to a long-distance night bus such as a long-distance night route bus or a long-distance night charter bus that rides for a long time with going to bed at night, without reducing the number of seats, and in the vicinity of passengers, particularly the rear seats. It is related with the seat structure which implement | achieves the relaxed attitude | position for enabling a comfortable night sleep, without hesitating a passenger.

  Buses are an important means of public transportation and are widely used as a foot in everyday life. In the past, most of the time was commuting, attending school, shopping, and other short-term rides for daily life, and frequent boarding and boarding in the same municipality or boarding in neighboring municipalities. However, in addition to the above-described modes of use, in recent years, coupled with the nationwide expansion and expansion of expressways, long-distance and long-time rides have increased dramatically as the flagship of intercity traffic. For this reason, not only daytime but also long-distance night route buses that use nighttime, which allows effective use of time, are rapidly spreading as a means of transportation and are widely established. Also, chartered buses with long-distance night service are widely used because of their convenience.

  As shown in FIG. 28, long-distance night buses B such as long-distance night route buses and long-distance night chartered buses as intercity traffic are prepared for passengers who are going to sleep for a long time at night. In order to reduce the size, a large bus having a total length of 9 m or more and less than 12 m and a width of less than 2.5 m adopting an arrangement structure in which single seats S are arranged in parallel in three rows in the width direction with the passages 7 in the longitudinal direction interposed therebetween, Large buses with a total length of more than 11 m are often used. Various ideas have been proposed for a reclining mechanism of a seat that is devised so that the user can sleep in a flatter state in order to make the riding environment comfortable, particularly in order to keep the posture at night sleeping comfortably.

  For example, in the relationship between the front seat and the rear seat, by setting the latter installation floor surface lower than the former installation floor surface, the passenger of the front seat does not bother the passenger of the rear seat, and the backrest has a maximum angle (160 degrees). ) And a reclining seat installation method that does not require an increase in the distance between both seats is provided (Patent Document 1). Furthermore, the idea of rearranging the seat into a two-stage bed is also provided at night (Patent Document 2).

  In a conventional riding form that repeats a short boarding or frequent boarding / exiting as before, there is relatively little concern about the riding posture or the like and the concern to surrounding passengers. However, on long-distance night buses with long night rides, especially nighttime sleep, it is possible to take a relaxed posture at bedtime or the relationship with surrounding passengers affects comfort, fatigue level and arrival place It is an important factor that affects the activities of the bus and directly affects the bus utilization.

The following points are actually pointed out by passengers as dissatisfaction points and improvement points of the long-distance night bus as a means of transportation.
(1) The legs cannot be extended sufficiently.
(2) The seat reclining angle is shallow and it is difficult to sleep.
(3) The seat reclining cannot be defeated to the limit because it will be annoying to the passengers in the rear seats.
(4) Because an unnatural posture lasts for a long time, it is impossible to sleep well, and there is a possibility that the legs may be swollen or blood flow may be impaired.
(5) Although it is convenient, the physical burden is large.
(6) Being able to sleep with an easy posture.

  The main selection criteria for passengers who use long-distance night buses who ride for a long time at night assuming bedtime are "fare", "comfort" (being less tired even if they ride for a long time), "service schedule" It is. Above all, with regard to “comfort”, it is required to realize a posture with less burden to enable sleeping at night. Therefore, passengers are requested to lie down on their seats at night, without having to put up with burdens and patience on their backseat passengers, and without being forced to endure themselves. Specifically, there is the most demand for a seat that can be reclined to a more flat state.

  Long-distance night buses are attractive due to the cheaper fare compared to other modes of transportation and the effective use of time by going to sleep at night, due to the longer travel distance due to the widespread use of expressways. As a means of transportation that continues to spread rapidly, many bus companies now offer various routes, and competition on the same route is intensifying.

  As shown in the explanatory diagram of the passenger selection criteria in the long-distance night bus in FIG. 26, the criteria when the passenger P selects the long-distance night bus can be roughly divided into fare F and comfortable if the operation schedule is different. Whether or not comfort C is determined based on whether or not comfortable sleep C1 can be achieved at night, and can be extended at night, or can the foot be held at a height close to the height of the head, Whether the sheet is almost flat or not is due solely to the sheet structure SC. In addition, the fare F is an important factor affecting the profitability E (see FIG. 27) of the bus company. However, the long-distance night bus has a lower price than existing transportation means. It is one of the big selling points to differentiate, and is currently exposed to intense price competition between bus companies under the market economy.

Therefore, the relationship between comfort C and profitability E will be verified with reference to FIG. 27, taking the following bus generally used as a long-distance night bus as an example.
Bus total length: 11.99m
Length from driver's seat rear partition plate to emergency exit door opening: 8.53m
Length from driver's seat rear partition plate to rear partition: 10.31m
Rear toilet part dimensions (width x length): 1.15m x 1.7m
Indoor width dimension: 2.31m
Indoor height of the central part: 1.8m
Indoor height to the bottom of the luggage rack on both windows: 1.47m
Number of sheets (width direction × length direction): 3 rows × 8 to 10 rows
= 26 seats to 28 seats Vertical seat interval: 900 mm to 970 mm

  Since the profitability E is determined by the number of seats N × the boarding rate R, in order to secure the profitability E, it is necessary to secure one or both of the number of seats N and the boarding rate R. In addition, in order to improve the comfort C, it is necessary to improve the comfort 300 of the seat and realize a comfortable sleep 310 at bedtime at night.

  If the seat comfort 300 can be improved by providing a reclining mechanism that allows the seat size and spacing, and in particular, a seat that is almost flat, it will be a differentiation success 320. Thus, it is possible to realize the boarding rate improvement 210, which is one element for improving the profitability E. However, the improvement in seat comfort 300 requires an increase in the installation area per seat at the time of reclining, which leads to a reduction in the number 330 of seats, leading to a deterioration 200 in profitability E.

  On the other hand, if the number of seats 220 is fulfilled in order to secure profitability E, the installation area per seat decreases, resulting in difficulty in realizing seat comfort 230, and in comfort C, difficulty in differentiating from other companies 240 It will be inferior to other companies. As a result, it becomes difficult to secure the boarding rate R by inviting the passenger 250, or the fare competition 260 is invited. As a result, profitability E deteriorates 200. Thus, the pursuit of profitability E and the improvement of comfort C are in conflicting directions, and it has been difficult to realize both at the same time.

  As shown in FIG. 29A, the current spacing D between the front and rear seats S remains in the range of 900 mm to 970 mm, so the reclining angle α of the front seat S is about 120 degrees as shown in FIG. However, no matter how the footrest and the backrest structure are devised, the seat structure SC that allows a comfortable night sleep cannot be realized. Therefore, in a long-distance night bus that rides for a long time, even if the seat S is reclined and the legs are extended, the toe position and the head position are not horizontal due to the fundamental seat structure SC. Will be sitting diagonally, and the body will try to slide down, making it difficult to sleep and swollen feet. Moreover, in some cases, anxiety that the economy class syndrome may develop is caused.

  In addition, the passenger BP in the rear seat is restricted in activity due to the reclining of the seat S by the passenger FP in the front seat. Become. Recently, several cases have been reported that this reclining causes a fight between passengers.

  If the current distance D between the front and rear sheets S of about 900 mm to 970 mm shown in FIG. 30A is expanded to the distance D1 of the front and rear sheets S of about 1900 mm to 2000 mm as shown in FIG. As shown in FIG. 30 (c), it is possible to extend the legs and recline the seat S to a nearly flat state without bothering the passengers in the rear seats, thereby realizing the comfort 300 of the seat S and other companies. And the boarding rate R, which is one factor of the profitability E, can be improved 210.

  However, in that case, the installation area per seat is increased, and the current seat S shown in FIG. 30 (a) can be installed in a space where six seats can be installed in the length direction of the long-distance night bus. Only half of the three seats can be installed as shown in (). Therefore, the number of seats that can be installed on the long-distance night bus B is reduced from the current 27 seats to about 12 seats (3 rows × 4 rows) as shown in the virtual layout of FIG. Further, as shown in the virtual layout diagram of FIG. 32, even if the installation direction of the seat S is arranged in a direction orthogonal to the longitudinal direction of the long distance night bus B, the number of seats that can be installed is only about 12 seats. Therefore, the number of sheets is reduced 330, and the number N of sheets, which is one factor of profitability E, cannot be secured, and as a result, profitability E deteriorates 200. 31 and 32, T is a toilet and EX is an emergency exit.

  As mentioned above, if the long-distance night bus with about 27 seats is operated with 12 seats, even if the average boarding rate is 80%, the average number of passengers per flight will be about 10, so that profits can be secured. Need to raise fares significantly. However, in order to compete with existing transportation means and cheap fare aircraft (LCC) that are advantageous in terms of time required, it is difficult to raise the fare significantly because it loses its competitiveness. And in order to acquire profits with the current fare, the number of seats is about 27.

  Therefore, the sales amount was verified by taking a long-distance night bus between Kochi City where the applicant is located and Tokyo as an example. Assuming that the number of seats N is 27 seats, the occupancy rate R is 80%, and the fare F is 12,000 yen, the estimated sales amount is [27 seats × 12,000 yen × 0.8 = 259,200 yen]. By the way, the average cost per one-way flight by the product manufacturing cost including fuel cost, high-speed fee, labor cost, ticket sales fee, vehicle depreciation cost, etc. is required about 187,000 yen, to cover this cost Requires [187,000 yen / 12,000 yen = 15.6 people]. If the occupancy rate R is 80%, [15.6 persons / 0.8 = 19.5 persons], that is, the number of seats N needs to be at least 20 seats.

  Temporarily, in order to realize the comfort C, the number of passengers is [12 seats × 0.8 = 9.6 people] when the above calculation is performed with 12 seats. Dividing the above average cost of 187,000 yen by 9.6 people yields [187,000 yen ÷ 9.6 people = 19,480 yen], which is the average cost per one-way flight based on product manufacturing costs of 187,000. To cover the yen, it is necessary to raise the fare by about 62.4% (7,480 yen). Therefore, although the comfort C is improved, the fare F has to be significantly increased, so that it is difficult to be selected by the passenger as a long-distance night bus.

  In recent years, some bus operators have been operating long-distance night buses with very few seats, largely because they have adopted a seat structure that allows them to sleep comfortably during night driving. However, the actual situation is nothing more than an advertising operation that ignores profitability E.

  If priority is given to securing the number N of seats for profitability E, comfort C cannot be secured, and profitability E deteriorates due to a decrease in the boarding rate R, while comfort C is emphasized. In this case, it is difficult to secure the number N of sheets, and as a result, profitability E deteriorates. Therefore, in the past, the seat structure that improved the comfort C without sacrificing the profitability E by securing the number N of seats that can maintain the profitability E, that is, both the profitability E and the comfort C No sheet structure that can satisfy the above has been provided.

  Therefore, the present invention solves the problems of the seat structure of the conventional long-distance night bus described above, secures the number of seats N that can maintain the profitability E, and is comfortable without worrying about passengers in the rear seats. An object of the present invention is to provide a bus seat structure with improved comfort C, which can realize a relaxed posture for enabling a good night sleep.

  As shown in the basic conceptual diagram of FIG. 1, the present invention achieves profitability E by simultaneously achieving 410 profitability E and comfort C, which have been conventionally considered difficult, that is, by securing 220 the number of seats. The present invention provides a seat structure for a long-distance night bus that realizes the comfort C without sacrificing and improving the comfort 300 of the seat. As a result, the boarding rate improvement 210 can be realized by achieving 320 differentiating success from other companies, and as a result, the increase 400 of passengers can be achieved, and the profitability E can be improved as a bus company. . Therefore, in the present invention, attention is paid to the installation space of seats necessary for enabling sufficient reclining, and the idea that the above-described conventional problems can be solved if the same installation space can be used by a plurality of seats.

  Embodiments of a seat structure for a long distance night bus according to the present invention will be described below with reference to the drawings. The long-distance night bus 1 to which the present invention is applied is not particularly limited as long as it is a night-long driving with sleep, but mainly involves night-long driving with sleep for intercity traffic. Intended for route buses or chartered buses. FIG. 2 is a side view showing an example of a long-distance night bus 1 as a long-distance night bus that employs the present invention. The total length is 11.99 m, and the length from the driver's seat rear partition plate to the rear partition is 10. This is a large bus of 31m, indoor width dimension: 2.31m, indoor height dimension in the center part: 1.8m, indoor height dimension to the lower part of the double-side luggage rack: 1.47m. The long-distance night bus 1 according to the present invention is not limited in size or number of passengers, and may be a medium or small bus.

  FIG. 10 is a perspective view of a pair of sheets 30 including a front sheet 10 and a rear sheet 20 according to the present invention, and FIG. 11 is a side view thereof. The front seat 10 and the rear seat 20 have backrests 12 and 22 that can recline (tilt) in the front-rear direction at a predetermined angle at the rear ends of the seat surfaces 11 and 21, respectively. In addition, legrests 13 and 23 that can be folded and extended are provided at the front ends of the seating surfaces 11 and 21, respectively. The legrests 13 and 23 also have a footrest function at the tip.

  A pair of sheets 30 consisting of the front sheet 10 and the rear sheet 20 is assembled into a frame 40 which is a strength member to form a unit. The frame 40 holds a pair of left and right base materials 41 composed of a left base material 41a and a right base material 41b, and a pair of left and right base materials 42 composed of a left girder material 42a and a right girder material 42b with a predetermined height H. The pair of left and right front struts 43a and right front struts 43b are connected by a pair of left and right front struts 43 and left and right rear struts 44a and right rear struts 44b. It is connected by the front beam 45 and the rear beam 46 while maintaining the width, and is formed in a hollow, substantially rectangular parallelepiped shape. Further, a fitting rod 48 is fixed at a predetermined position between the left rear column 44a and the right rear column 44b above the backrest 22 of the rear seat 20 assembled to the frame 40.

  As will be described later, the fitting rod 48 is for receiving and supporting the backrest 12 when the backrest 12 of the front seat 10 is reclined, and is required to be installed at a predetermined position. Therefore, in order not to obstruct the reclining of the backrest 22 of the rear seat 20 and to be installed at a position where the backrest 12 of the reclining front seat 10 can be supported, the space between the left rear column 44a and the right rear column 44b. In this case, it is preferable that the position can be changed or removed. If it is laid, if the fitting rod 48 is fixed at a position suitable for supporting the backrest 12 of the reclining front seat 10, it will be removed at all times in the case where the reclining of the backrest 22 of the rear seat 20 becomes an obstacle. Alternatively, it may be installed at a predetermined position when sleeping at night when it is necessary to support the backrest 12 of the front seat 10 by installing it at another position.

  In the present embodiment, a pair of seats 30 assembled in a frame 40 are placed on the floor of the long-distance night bus 1 in the width direction with the passage 7 in the longitudinal direction therebetween, and one window side area, the central area, and the other 3 rows were juxtaposed in the window side area, and 4 sets of each row were installed in the longitudinal direction. In addition, since there is no space for installing the fifth pair of sheets 30 at the last part, the single sheet 5 having the same structure as the front sheet 10 and the rear sheet 20 is excluded except for the space on one window side, Two seats were installed behind the fourth pair of seats 30 (see FIGS. 2 to 6). A toilet (not shown) is installed in the rear space of the other window side area. Therefore, the number of seats in the long-distance night bus 1 was 26 seats [2 seats (a pair of seats 30) × 3 rows (width direction) × 4 rows (longitudinal direction) +2 seats (single seat 5)].

  As shown in FIG. 7, in the longitudinal direction of the floor 2 of the long-distance night bus 1, six lower rails 50a, 50b, 51a, 51b, 52a, 52b as strength members are spaced apart in the width direction by a predetermined distance. It is laid vacantly. In addition, four upper rails 53b, 54a, 54b, and 55a as strength members are laid on the ceiling surface 3 at predetermined intervals in the width direction.

  As shown in FIG. 8, four sets of frames 40 installed in the longitudinal direction of the central area are slidably installed by the lower rails 51a and 51b and the upper rails 54a and 54b. Specifically, the left base material 41a is slidably installed on the lower rail 51a, the right base material 41b is slidably installed on the lower rail 51b, the left spar material 42a is the upper rail 54a, and the right spar material 42b is the upper rail 54b. It is slidably installed. Thereby, the frame 40 assembled with the pair of seats 30 can slide in the longitudinal direction of the long distance night bus 1 via the lower rails 51a and 51b and the upper rails 54a and 54b.

  Since the luggage rack 4 is installed above the one and other window side areas, as shown in FIG. 8, the frame 40 installed in one window side area has the left base material 41a as the lower rail 50a and the right side. The base material 41b is slidably installed on the lower rail 50b, the right girder member 42b is extended upward, and is slidably installed on the upper rail 53b, and the left girder member 42a is not installed on the rail. .

Sit on the surfaces 11 and 21 and get on. As shown in FIG. 18, the bedtime during night driving is such that the front seat 10 and the rear seat 20 constituting the pair of seats 30 are moved vertically by moving the front seat 10 to the upper space of the rear seat 20. It is characterized by being installed on substantially the same line.

  In the substantially same row in the horizontal direction, between the front sheet 10 and the rear sheet 20 constituting the pair of sheets 30 and between the pair of sheets 30 installed in the width direction and the longitudinal direction in the long distance night bus 1. The rear seat 20 exists before and after the front seat 10 in the horizontal direction, and the front seat 10 exists before and after the rear seat 20 in the horizontal direction, that is, the front seat 10 and the rear seat 20 are on the same plane. (Refer to FIGS. 2, 10, and 11).

  “On substantially the same line in the vertical direction” means that the front seat 10 and the rear seat 20 constituting the pair of seats 30 or a pair of seats 30 installed in the width direction and the longitudinal direction in the long-distance night bus 1 are mutually connected. The rear seat 20 is not present before and after the front seat 10 in the horizontal direction, and the front seat 10 is not present before and after the rear seat 20 in the horizontal direction, that is, the front seat is substantially directly above the rear seat 20. In the state where 10 is located, if it is spread, the front seat 10 and the rear seat 20 are in a state of sharing the whole or a part of the installation space in the vertical direction (FIGS. 3, 4 and 4). 9, FIG. 16, FIG. 17, FIG. 18, FIG. 19, FIG. 22, FIG.

  As described above, by installing the front sheet 10 and the rear sheet 20 constituting the pair of sheets 30 on substantially the same line in the vertical direction, the installation area of the pair of sheets 30 is dedicated to both the front sheet 10 and the rear sheet 20. Each area can be used independently. That is, the horizontal space of the front seat 10 and the rear seat 20 is opened, and the backrest 12 of the front seat 10 can be reclined using the open space without interfering with the rear seat 20 (FIG. 18). Similarly, the backrest 22 of the rear seat 20 can be reclined without interfering with the front seat 10 of the pair of seats 30 installed rearward (see FIGS. 3 and 18).

  As described above, the frame 40 assembled with the pair of seats 30 includes the upper rails 54a and 54b (upper rail 53b or upper rail 55a) as the strength members laid on the ceiling surface 3 of the long distance night bus 1 and the floor surface 2. Are supported slidably between lower rails 51a and 51b (lower rails 50a and 50b or lower rails 52a and 52b) as strength members laid on the rail. When the front seat 10 and the rear seat 20 constituting the pair of seats 30 are installed in substantially the same row in the horizontal direction, as shown in FIG. 11, a predetermined fixture fixed to the floor surface 2 of the long-distance night bus 1 6, the front legs 16 suspended from the left and right ends of the lower surface of the front end portion of the seat surface 11 of the front seat 10 are detachably attached and fixed. Thereby, the frame 40 assembled with the pair of seats 30 is fixed at a predetermined position between the floor surface 2 and the ceiling surface 3 of the long-distance night bus 1 (see FIG. 2). In the state where the front leg 16 is removed from the fixture 6, the frame 40 has the upper rails 54a and 54b (upper rail 53b or upper rail 55a) and the lower rails 51a and 51b (lower rails 50a and 50b or lower rails 52a and 52b). ). The fixing means is not particularly limited, and an appropriate means is selected from known detachable fixing means. In addition to the fixture 6, the frame 40 itself is detachably fixed to the upper rails 53b, 54a, 54b, 55a, the lower rails 50a, 50b, 51a, 51b, 52a, 52b, or to the floor surface 2 and the ceiling surface 3. Means may be added. The front legs 26 and the rear legs 24 of the rear seat 20 are fixed to a pair of left and right base materials 41, respectively.

  A pair of left and right rear legs 14 suspended from the lower surface of the rear end portion of the seat surface 11 of the front seat 10 and a pair of left and right bases 41 are connected by a pair of left and right support rods 60 that can be raised and lowered. The front end 60 a of the support rod 60 is rotatably connected to the rear leg 14, and the base end 60 b is rotatably connected to the base material 41. A rod 71 of the gas cylinder 70 is rotatably connected to a predetermined position of the intermediate portion of the support rod 60, and a head 72 of the gas cylinder 70 is rotatably connected to a predetermined position of the base material 41. . By releasing the fixing member 6 of the front seat 10, the gas pressure of the gas cylinder 70 is released and the rod 71 is extended, so that the support rod 60 serves as a fulcrum as shown in FIG. 21. As a result, the front seat 10 is lifted upward.

  A pair of left and right seating surface long holes 15 are formed on the lower surface of the seating surface 11 of the front seat 10 so as to be connected to the rear leg 14. As shown in FIG. 20, a connecting rod 80 is slidably inserted into the seat surface long hole 15, and both ends thereof are protruded from the seat surface long hole 15, so that one end portion 81 a of the pair of left and right links 81 is formed. It is connected. Then, an engaging projection 82 is provided on the outer end surface of the other end 81b of the link 81, and the engaging projection 82 is formed on the left front column 43a and the right front column 43b so as to face each other in the longitudinal direction. 47 is slidably engaged (see FIG. 15).

  Therefore, by extending the rod 71 of the gas cylinder 70, the support rod 60 is erected, the engagement protrusion 82 slides upward along the slide groove 47, and the connection rod 80 is seated in the long hole 15 of the seat surface. By sliding and displacing the front seat 10, the front seat 10 can be moved to the upper space of the rear seat 20, and the front seat 10 and the rear seat 20 can be installed on substantially the same line in the vertical direction.

  The standing angle of the support rod 60 is preferably approximately 90 degrees as in the illustrated example, but there is no particular limitation, and the standing angle depends on the indoor height of the long-distance night bus 1, for example, the indoor height depending on the presence or absence of the luggage rack 4. May be set as appropriate. If necessary, the front seat 10 and the rear seat 20 share the whole or a part of the installation space in the vertical direction so that the front seat 10 and the rear seat 20 each have a backrest 12 using the installation space. , 22 can be reclined and the legrests 13, 23 can be extended. In addition, when the standing angle of the support rod 60 exceeds 90 degrees, the design of the front seat 10 may be appropriately changed so that the link 81 can be folded or stretched so that the operation is not hindered. . If necessary, the configuration in which the front sheet 10 and the rear sheet 20 in the pair of sheets 30 can be installed in substantially the same row in the horizontal direction and the front sheet 10 can be moved to the upper space of the rear sheet 20 is selected. That's fine. Hereinafter, the detail of the example is demonstrated based on FIGS.

[Step 1 / FIG. 10, FIG. 11]
Outside the bedtime during night driving, the front seat 10 is attached to a predetermined fixture 6 that fixes the front leg 16 to the floor 2 of the long-distance night bus 1 as shown in FIGS. It is fixed at a predetermined position on the floor 2 of the long-distance night bus 1. Thereby, the passenger P can be seated on the front seat 10 and the rear seat 20 while the pair of seats 30 is traveling. In addition to the fixture 6, a means for fixing the pair of sheets 30 to a predetermined position of the long distance night bus 1 may be added. In this state, the connecting rod 80 is positioned at the end of the seat surface long hole 15 in the direction of the backrest 12, and the engaging protrusion 82 is positioned in the direction of the base material 41 of the sliding groove 47. Further, the gas cylinder 70 is held in a contracted state, and is stored together with the support rod 60 in the base material 41.

[Step 2 / FIGS. 12 and 17]
In the sleeping time zone during night driving, the front seat 10 is moved to the upper space of the rear seat 20 as shown in FIG. The front seat 10 and the rear seat 20 constituting the above are installed on substantially the same line in the vertical direction. Thereby, the backrests 12 and 22 of the front seat 10 and the rear seat 20 can be reclined to a nearly flat state.

  For this purpose, as shown in FIG. 12, the gas in the gas cylinder 70 is released in conjunction with the release of the fixing of the front leg 16 of the front seat 10 by the fixture 6. By this operation, the rod 71 is extended, the support rod 60 is pushed by the rod 71, and the base end portion 60b that is rotatably connected to the base material 41 is pivoted to start standing. The front leg 16 removed from the fixture 6 can be folded and stored on the lower surface of the seat surface 11. When the support rod 60 stands up, a force to be lifted upwards acts on the rear leg 14 to which the distal end portion 60a of the support rod 60 is coupled, and the coupling rod 80 moves in the distal direction in the seat surface long hole 15 to move the distal end. After that, the engaging projection 82 of the link 81 slides and moves upward in the sliding groove 47, and the front seat 10 gradually moves upward while tilting backward as indicated by arrows 100 and 105. Begin to lift.

[Step 3 / FIG. 13]
Thereafter, in conjunction with the standing of the support rod 60, as shown by an arrow 110, the front seat 10 continues to rise while tilting backward, and from the state shown in FIG. 12 to the link 81 as shown in FIG. As it becomes parallel to 47, the connecting rod 80 starts to move from the front end toward the rear end in the seat surface long hole 15, and the front seat 10 starts to move rearward as indicated by an arrow 115.

[Step 4 / FIG. 14]
Further, as shown by an arrow 120, the link 81 rotates from the state shown in FIG. 13 with the engaging projection 82 in the sliding groove 47 as a fulcrum as shown in FIG. Then, the movement continues in the rear end direction (rear strut 44 direction) in the seat surface long hole 15 beyond the sliding groove 47, and the connecting rod 80 collides with the rear end of the seat surface long hole 15 and stops. By this operation, the forwardly inclined front seat 10 returns its posture so as to be parallel to the base material 41 as indicated by arrows 125 and 130, and moves as a whole toward the rear strut 44 as indicated by an arrow 135. .

[Step 5 / FIG. 15]
Thereafter, as shown by an arrow 140, in conjunction with the standing of the support rod 60, the connecting rod 80 is changed from the state shown in FIG. 14 to the seat surface length with the engaging protrusion 82 of the link 81 as a fulcrum as shown in FIG. The inside of the hole 15 is reversed and moved in the tip direction. As a result of this operation, the front seat 10 tilted rearward is returned to its posture so as to be parallel to the base material 41 as indicated by arrows 145 and 150, and is moved in the direction of the rear support 44 as a whole as indicated by arrows 155. To do.

[Step 6 / FIG. 16]
When the standing of the support rod 60 is completed, as shown in FIG. 16, the front seat 10 is supported by the gas cylinder 70 and fixed substantially directly above the rear seat 20, and the front seat 10 and the rear seat 20 are in the vertical direction. Align on approximately the same line. At this time, the seat surface 11 of the front seat 10 is parallel to the seat surface 21 of the rear seat 20. Further, the connecting rod 80 is positioned at the tip of the seating surface long hole 15, and the link 81 is positioned substantially parallel to the seating surface long hole 15. In the state shown in FIG. 16, the front seat 10 is supported by the support rod 60 and is fixed at a position almost directly above the rear seat 20, so that the passenger P can be seated.

[Step 7 / FIGS. 17, 18, and 19]
Further, in order to enhance safety, as shown in FIGS. 17 and 18, a pair of left and right fixing rods 65 mounted on a pair of front struts 43 (a left front strut 43a and a right front strut 43b) are attached to and detached from the side surface of the front seat 10. By freely connecting and fixing, the front seat 10 is fixed to the pair of front struts 43, and the fixing of the front seat 10 by the support rod 60 is assisted. Further, as shown in FIG. 19, a concave fitting material (not shown) provided on the back surface of the backrest 12 of the front seat 10 is fitted into a fitting rod 48 fixed between a pair of left and right rear struts 44. The backrest 12 is supported and fixed. Therefore, when the front seat 10 and the rear seat 20 are installed on the substantially same line in the vertical direction, the front seat 10 is firmly fixed at three points by the fixing rod 65, the support rod 60, and the fitting rod 48 as shown in FIG. It is fixed and secures safety. In the illustrated example, the fixing rod 65 is mounted on the pair of front struts 43, but the mounting location is not limited, and the pair of beam members 42 (the left beam member 42a and the right beam member 42b) may be mounted. . If the front seat 10 can be firmly fixed at the three points of the fixing rod 65, the support rod 60, and the fitting rod 48, there is no restriction on the configuration and the equipment location.

  As shown in FIG. 17, by installing the front sheet 10 and the rear sheet 20 constituting the pair of sheets 30 on substantially the same line in the vertical direction, the horizontal space of the front sheet 10 and the rear sheet 20 is opened, Using the open space, as shown in FIG. 18, the backrest 12 of the front seat 10 is moved 180 degrees or at least about 160 degrees or more to 180 degrees as shown by an arrow 160 without interfering with the rear seat 20. In addition, by extending the legrest 13 as shown by an arrow 165, the legrest 13, the seating surface 11, and the backrest 12 are installed in a state close to a full flat shape that is substantially straight. Can do.

  Similarly, as shown in FIG. 18, the back seat 20 of the rear seat 20 is set to 180 degrees or at least about 160 degrees to 180 degrees without interfering with the front seat 10 of the pair of seats 30 installed on the rear side. The leg rest 23, the seating surface 21, and the backrest 22 can be installed in a substantially flat state where the leg rest 23, the seat surface 21, and the backrest 22 are substantially straight.

  Therefore, as shown in FIG. 19, both the front seat 10 and the rear seat 20 can tilt the backrests 12 and 22 to a sufficient angle without worrying about the passengers in the rear seats. Combined with the extension of the foot, it is possible to lie down with the legs fully stretched, and to be able to sleep comfortably at night. In addition, as a facility for the passenger P to easily climb the front seat 10, lifting means such as appropriate stairs (not shown) are installed on the pair of seats 30.

  In the present embodiment, as shown in FIG. 2, the space for installing the fifth pair of seats 30 does not remain at the last part of the long-distance night bus 1, so that it is the same as the front seat 10 and the rear seat 20. In order to secure the number of seats, the single seat 5 having the structure is arranged in parallel behind the pair of seats 30d of the fourth set, excluding the space on one window side, and two seats are installed in parallel. As shown in FIG. 3 and FIG. 4, due to the presence of the single seat 5, the backrest 22 of the rear seat 20 of the fourth pair of sheets 30 d positioned in front of the single seat 5 is damaged by the single seat 5. It can not be defeated to a sufficient angle. Similarly, the backrests 12 and 22 of the front seat 10 and the rear seat 20 of the fourth pair of seats 30d located in front of the toilet T cannot be tilted to a sufficient angle because the toilet T becomes an obstacle.

  On the other hand, the installation location of the pair of seats 30 with respect to the floor surface 2 in a state where the front seat 10 is moved to the upper space of the rear seat 20 is determined by the position of the rear seat 20, and as shown in FIGS. In addition, a surplus space 9 is formed in front of the first pair of seats 30a close to the driver's seat. Therefore, as shown in FIGS. 5 and 6, the upper rail 54a as a strength member laid on the ceiling surface 3 of the long-distance night bus 1, with the frame 40 assembled with the pair of seats 30 shown in FIGS. 54b (upper rail 53b or upper rail 55a) and lower rails 51a and 51b (lower rails 50a and 50b or lower rails 52a and 52b) as strength members laid on the floor surface 2 for long distance night buses Move to the front of 1. Thereby, a space can be secured behind the pair of seats 30d of the fourth set, and the backrests 12, 22 of the pair of seats 30d of the fourth set can be sufficiently secured without causing the single seat 5 or the toilet T to become an obstacle. It is possible to defeat to a certain angle. At the same time, a passage 8 in the width direction for securing a flow line from the longitudinal direction 7 to the toilet T can be formed from all the sheets. In the example shown in FIG. 6, the passage 8 in the width direction is formed in front of the fourth pair of seats 30 d located at the center of the floor surface 2, but the position is not limited, and if necessary, all passengers It is only necessary to secure a flow line that can move to the toilet T.

  Further, since there is a space between the single sheet 5 and the fourth pair of sheets 30d positioned in front of the single sheet 5, the single sheet 5 can be independently moved forward by a known mechanism. By configuring, the backrest 5a of the single seat 5 can be reclined to a sufficient angle as shown in FIGS. 5 and 6, and the legrest 5b can also be extended.

  The backrests 12 and 22 of the front seat 10 and the rear seat 20 may be reclined (backward tilted) to about 180 degrees so as to be in a fully flat state with respect to the seating surfaces 11 and 21. In addition, when it is difficult to realize a full flat state only by reclining the backrests 12 and 22, when the backrests 12 and 22 of the front seat 10 or the rear seat 20 are reclined as shown in FIG. The seating surfaces 11 and 21 and the backrests 12 and 22 are reclined (backward tilted) to a maximum angle, for example, about 160 degrees, so that the angle between the seating surfaces 11 and 21 and the backrests 12 and 22 is V-shaped. By changing the installation angle of the seat surfaces 11 and 21 and the backrests 12 and 22, the V-shaped valley formed between the seat 21 and the backrests 12 and 22, as shown in FIG. The backrests 12 and 22 can be substantially flat. Specifically, cam mechanisms 90 for changing the angle are provided on the lower surfaces of the end portions of the seat surfaces 11 and 21 and the lower surfaces of the end portions of the backrests 12 and 22.

  In addition, about the front sheet | seat 10, the angle of the seat surface 11 and the backrest 12 can be set so that it may become V shape with respect to the floor surface 2 by adjusting the undulation angle of the support rod 60 suitably. As for the rear seat 20, when the backrest 22 is reclined, the front leg 26 is configured to be detachable from the base material 41 and removed from the base material 41, and the rear leg 24 is rotated with respect to the base material 41. The angle of the seat surface 21 and the backrest 22 can be set to be V-shaped with respect to the floor surface 2 by being configured to be movable and rotating to a predetermined angle. The single sheet 5 is the same as the rear sheet 20.

  As shown in FIG. 24B, the cam mechanism 90 has a plurality of elliptical cams 91 (two in the illustrated example) having different curvatures at both ends in the major axis direction at predetermined positions on the shaft 92. And an operating rod 93 is connected to one end of the shaft 92. By rotating the operating rod 93, the end 91a having a small curvature of the long diameter portion is rotated from a horizontal state as shown in FIG. 24B to a vertical state as shown in FIG. 25B. Standing up and being held in that state. When the end portion 91a is rotated and stands, the end portion of the seating surface 11 (21) and the end portion of the backrest 12 (22) are lowered into a V shape in FIGS. 22 and 24A. Therefore, as shown by an arrow 170 in FIGS. 23 and 25A, the seating surface 11 (21) and the backrest 12 (22) can be lifted to a substantially flat state.

  By adopting this cam mechanism 90, even when the backrests 12 and 22 do not reach a full flat shape by reclining, a full flat state can be realized as a result, and the comfort at the time of sleeping is leap. Can be improved.

  The first feature of the present invention described above is the same number as the conventional long-distance night bus without sacrificing the number of seats in order to improve the comfort of the seats, particularly the comfort at bedtime at night. The sheet can be secured. That is, in a large bus having a total length exceeding 11 m that employs an arrangement structure in which single-seat seats are arranged in parallel in three rows in the width direction with passages therebetween, the number of seats of about 27 seats as in the conventional case is secured. be able to. Specifically, when traveling in a time zone that does not require sleeping in a flat state, the front and rear of a long-distance night bus seat that has a seat and a backrest and is installed according to the number of passengers By installing a pair of seats made up of seats on substantially the same line in the horizontal direction, it is possible to secure the number of seats necessary for maintaining profitability.

  The second feature of the present invention is that a pair of two-seat seats is provided for nighttime running when it is desirable to sleep in a flat state in order to improve comfort while ensuring the number of seats described above. By moving the front sheet of the sheet to the upper space of the rear sheet and installing the pair of sheets on substantially the same line in the vertical direction, the installation area of the pair of sheets is individually set as the dedicated area for the front sheet or the rear sheet. By making it possible to recline the backrest of the front seat to a nearly flat state without interfering with the rear seat, the comfort of the seat, particularly at night, can be greatly improved. be able to.

  Specifically, it is possible to solve the problems related to comfort, particularly seat reclining, which are pointed out by passengers as dissatisfaction points and improvement points of a long-distance night bus as a moving means. Therefore, according to the present invention, the legs can be extended sufficiently, the angle of the seat reclining becomes deep and it becomes easy to sleep, and the seat reclining can be freely performed without causing trouble or concern for the passengers in the rear seat. Can be defeated to the limit. Therefore, even when sleeping at night, you can ride and sleep in a comfortable posture with less physical burden, and it is cheaper than other transportation facilities, and you can effectively use time by sleeping and moving at night. You can enjoy the charm of long-distance night buses. As a result, many bus companies provide various routes, and in the long-distance night bus industry where competition on the same route is intensifying, it is possible to achieve differentiation from other companies, which can contribute to an improvement in the boarding rate.

  According to the present invention having the first and second characteristics described above, the seat comfort is improved without sacrificing profitability by securing the number of seats necessary for ensuring profitability. Therefore, it is possible to provide comfort, and to provide a seat structure for a long-distance night bus that can simultaneously achieve both profitability and comfort that have been considered difficult.

  Further, when the pair of seats are installed in substantially the same row in the vertical direction, when the backrest of the front seat or the rear seat is reclined, the angle of the seating surface and the backrest becomes V-shaped with respect to the floor surface. The seating surface and backrest can be made substantially flat by changing the angle of the seating surface by turning the cam and rotating the cam. It is possible to go to bed.

  Therefore, according to the present invention, it is possible to achieve both profitability and comfort, which have been regarded as difficult in the past, and to achieve an increase in the boarding rate by differentiating from other companies. An increase can be achieved, and it becomes possible to improve profitability as a bus company.
