Description

Technical Field

[0001] This utility model belongs to the field of sightseeing vehicle technology, specifically relating to an adjustable seat for sightseeing vehicles. Background Technology

[0002] Sightseeing vehicles operating in amusement parks and scenic areas, primarily for transporting tourists, typically have seats fixed to the vehicle body with integrated seat backs that cannot be adjusted forward or backward. Passengers are confined to the existing seating space. Since tourists in amusement parks and scenic areas vary in size, the fixed seating space results in poor comfort for passengers of varying sizes.

[0003] To address the aforementioned issues, current solutions often involve sliding the seat back onto the seat support surface. However, this sliding mechanism fails to meet the angle adjustment requirements of the seat back. To meet these requirements, the entire seat would have to slide forward and backward, which contradicts the original intention of solving the technical problems. Summary of the Invention

[0004] This invention addresses the problem that existing sightseeing vehicle seats cannot simultaneously provide both fore-and-aft sliding adjustment and tilt angle adjustment functions. It provides an adjustable sightseeing vehicle seat that further improves seat comfort by making the seat back adjustable fore-and-aft and facilitating angle adjustment.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: An adjustable seat for a sightseeing vehicle includes a seat board, armrests fixedly mounted on both sides of the seat board, a seat back and a seat cushion mounted above the seat board. The seat cushion is positioned between the front side of the seat back and the seat board. The seat back's position and angle relative to the seat board are adjustable. By adjusting the position of the seat back, it can accommodate passengers of different body types. In addition, by adjusting the angle of the seat back, passenger comfort can be improved.

[0006] Preferably, the two armrests are respectively provided with a first chamber and a second chamber. The two armrests are provided with grooves on opposite sides that communicate with the first chamber and the second chamber respectively. The first chamber and the second chamber are each provided with a moving component and a rotating component that slide back and forth. The moving component and the rotating component are both connected to the seat back and move back and forth synchronously with the seat back through the moving component.

[0007] Preferably, at least two telescopic rods are fixedly installed at the top of the first chamber, and tension springs are sleeved on the outer side of the telescopic rods. A pressure plate is fixedly installed below the telescopic rods. The two ends of the tension springs are respectively fixedly connected to the top surface of the first chamber and the upper surface of the pressure plate. The telescopic rods ensure that the pressure plate can be raised and lowered vertically, and the tension springs ensure that the pressure plate returns to its original position after moving downward.

[0008] Preferably, a plurality of limiting components are arranged in a front-to-back pattern below the pressure plate. The limiting components include strip grooves opened on two opposite side walls of the first chamber, sliders slidably disposed in the strip grooves, a fixed rod fixedly disposed between the two sliders, and two limiting rods rotatably sleeved on the fixed rod. The two limiting rods are arranged in a scissor shape. The upper end of the limiting rod contacts the lower side of the pressure plate, and the lower end is connected to a pawl. As the pressure plate moves down, the corresponding two limiting rods on the same fixed rod rotate, causing the two pawls to move closer to or further away from each other.

[0009] Preferably, each of the moving components includes a first gear and a rack portion. A rack portion is fixedly disposed on the inner bottom surface of both the first chamber and the second chamber. The first gear meshes with the corresponding rack portion. The first gear is rotatably connected to the seat back. The first gear moves along the rack portion by rotating.

[0010] The first gear in the first chamber corresponds vertically to a limiting component, and the pawl of the limiting component extends between two adjacent teeth of the corresponding first gear, thereby limiting the rotation of the first gear by the pawl.

[0011] Preferably, the rotating assembly includes a second gear, and the second gear is rotatably disposed in both the first chamber and the second chamber. The second gear is fixedly connected to the seat back via a connecting shaft, which passes through a corresponding groove. The second gear in the first chamber corresponds vertically to a limiting assembly, and the pawl of the limiting assembly extends between two adjacent teeth of the corresponding second gear to limit the rotation of the second gear.

[0012] Preferably, two opposing sliding blocks are slidably arranged in both the first chamber and the second chamber. The moving component and the rotating component are both arranged between the two sliding blocks. A sliding rod is fixedly arranged on one side of one of the sliding blocks. The sliding rod slides and matches the corresponding groove. The first gear and the second gear are rotated and installed through the sliding blocks. The moving component and the rotating component are stably supported by the first gear and the sliding rod.

[0013] Preferably, the top of the first chamber has a through hole that extends upward through the corresponding armrest plate. A button post is slidably installed in the through hole. The lower end of the button post contacts the pressure plate and the upper end extends out of the armrest plate. Pressing the button post can move the pressure plate downward.

[0014] Preferably, a downwardly inclined trapezoidal frame is fixedly provided on the upper side of the backrest of the seat. The bottom two ends of the trapezoidal frame are located above the armrest. The trapezoidal frame limits the rotation of the seat back and supports it when the lower end of the trapezoidal frame contacts the armrest.

[0015] Preferably, a round rod is rotatably provided between the two slide rods, and the round rod is located on the back side of the seat back. One end of the seat cushion is fixed to the upper rear side of the seat back, and the other end passes in sequence through the front side of the seat back, around the round rod, over the upper side of the seat board in front of the seat back, around the front end of the seat board, and is then stored in the winding device under the seat board. By driving the winding device to wind up or release the seat cushion, the seat cushion adapts to the back-and-forth movement of the seat back.

[0016] The beneficial effects of this utility model through the above technical solution are as follows: 1. This utility model involves pressing down on the button post to move the pressure plate downwards. The pressure plate presses down on the top of the limiting rod, causing the two corresponding limiting rods on the same fixed rod to rotate in opposite directions. This causes the pawl at the bottom of the limiting rod to open, releasing the limiting on the first and second gears. At this time, the seat back can be rotated to adjust its angle or slid back and forth along the groove. After adjustment, the button post is released, and the pressure plate moves up and resets under the action of the tension spring. The limiting rods reset under their own gravity.

[0017] 2. This utility model uses a trapezoidal frame fixedly installed on the upper side of the backrest of the seat. When the backrest is adjusted to a certain angle, the lower part of the trapezoidal frame contacts the upper side of the two armrests. At this time, the trapezoidal frame supports the backrest of the seat and prevents the backrest from tilting too much.

[0018] 3. This utility model ensures the comfort of the seat by laying a cushion on the front side of the seat back and the upper side of the seat board in front of the seat back. At the same time, the lower end of the cushion is stored on a corresponding rolling device. When the seat back is adjusted, the cushion is released or rolled up by the rolling device to ensure the adaptive adjustment of the cushion length. Attached Figure Description

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-10 As shown, this embodiment provides an adjustable seat for a sightseeing vehicle, including a seat board 1, armrests 3 fixedly mounted on both sides of the seat board 1, a seat back 4 and a seat cushion 5 mounted above the seat board 1. The seat cushion 5 is located between the front side of the seat back 4 and the seat board 1. The seat back 4 is adjustable in both its front-to-back position and angle relative to the seat board 1. By adjusting the position of the seat back on the seat board 1 and adjusting the tilt angle of the seat back, comfort for passengers of different body types and with different body types can be ensured.

[0031] Each of the two armrests 3 has a first chamber 6 and a second chamber 7 respectively. Each of the two armrests 3 has a groove 8 on its opposite side that communicates with the first chamber 6 and the second chamber 7 respectively. Each of the first chamber 6 and the second chamber 7 has a moving component and a rotating component that are slidably arranged back and forth. Both the moving component and the rotating component are connected to the seat back 4. The moving component is used to limit the movement of the seat back 4 so that it can only move in the back and forth direction. The rotating component is used to realize the rotating installation of the seat back 4.

[0032] At least two telescopic rods 9 are fixedly installed at the top of the first chamber 6. A tension spring 10 is sleeved on the outside of the telescopic rod 9. A pressure plate 11 is fixedly installed below the telescopic rod 9. The two ends of the tension spring 10 are fixedly connected to the top surface of the first chamber 6 and the upper side of the pressure plate 11, respectively. That is, the pressure plate 11 is slidably installed in the first chamber 6. The tension spring 10 is fixedly installed between the pressure plate 11 and the top surface of the first chamber 6. By pressing the pressure plate 11 downward, the telescopic rod 9 is extended and the tension spring 10 is stretched. When no external force is applied to the pressure plate 11, the pressure plate 11 moves upward and resets under the tension of the tension spring 10.

[0033] Below the pressure plate 11, there are multiple limiting components arranged in a front-to-back pattern. Each limiting component includes a strip groove 12 opened on two opposite side walls inside the first chamber 6, a slider 13 slidably disposed in the strip groove 12, a fixed rod 14 fixedly disposed between the two sliders 13, and two limiting rods 15 rotatably sleeved on the fixed rod 14. The two limiting rods 15 are arranged in a scissor shape. The portion of the limiting rod 15 below the fixed rod 14 is longer than the portion above the fixed rod 14. The upper end of the limiting rod 15 contacts the lower side of the pressure plate 11, and the lower end is connected to a pawl 16. When the pressure plate 11 moves down, it presses down on the upper ends of the two limiting rods 15 of each limiting component, causing the two limiting rods 15 to rotate in opposite directions. The upper and lower ends of the two limiting rods 15 move away from each other, and consequently, the two pawls 16 move away from each other.

[0034] Each of the moving components includes a first gear 17 and a rack portion 18. A rack portion 18 is fixedly provided on the bottom surface of the first chamber 6 and the second chamber 7. The first gear 17 meshes with the corresponding rack portion 18. The first gear 17 is rotatably connected to the seat back 4. When the seat back 4 is pushed to move back and forth, the first gear 17 rotates and moves along the rack portion 18.

[0035] The first gear 17 in the first chamber 6 corresponds vertically to a limiting component, and the pawl 16 of the limiting component extends between two adjacent teeth of the first gear 17. When the pawl 16 disengages from the first gear 17, it can push the seat back 4 to move back and forth. After the movement is completed, the pawl 16 extends between the teeth of the first gear 17. At this time, due to the pawl 16, the first gear 17 cannot rotate, and thus the seat back 4 cannot move, so that the passenger can lean against the seat back 4.

[0036] The rotating assembly includes a second gear 19, which is rotatably disposed in both the first chamber 6 and the second chamber 7. The second gear 19 is fixedly connected to the seat back 4 via a connecting shaft 20, which passes through the corresponding groove 8. When the seat back 4 is rotated, the second gear 19 rotates synchronously.

[0037] The second gear 19 in the first chamber 6 corresponds vertically to a limiting component, and the pawl 16 of the limiting component extends between two adjacent teeth of the corresponding second gear 19. When the pawl 16 disengages from the second gear 19, the tilt angle of the seat back 4 can be adjusted by rotation. After adjustment, the pawl 16 extends between the teeth of the second gear 19. At this time, due to the pawl 16, the second gear 19 cannot rotate, and thus the seat back 4 cannot rotate, allowing the passenger to lean against the seat back 4.

[0038] Two opposing sliding blocks 21 are slidably disposed in both the first chamber 6 and the second chamber 7. The moving component and the rotating component are both disposed between the two sliding blocks 21. A sliding rod 22 is fixedly disposed on one side of one of the sliding blocks 21. The sliding rods 22 are slidably matched with the corresponding grooves 8. Specifically, a first gear 17 and a second gear 19 are rotatably disposed between the two opposing sliding blocks 21. The number of first gears 17 is set to two and they are symmetrically arranged about the second gear 19. The lower part of the first gear 17 extends out between the two sliding blocks 21 and meshes with the rack part 18. There is a gap between the second gear 19 and the rack part 18.

[0039] The top of the first chamber 6 has a through hole that extends upward through the corresponding armrest plate 3. A button post 23 is slidably installed in the through hole. The lower end of the button post 23 contacts the pressure plate 11 and the upper end extends out of the armrest plate 3. By pressing the button post 23, the pressure plate 11 moves downward, the limiting rod 15 of the limiting component opens, and the pawl 16 disengages from the first gear 17 and the second gear 19. After releasing the button post 23, the pressure plate returns to its original position under the tension of the tension spring 10, and the pawl 16 locks the first gear 17 and the second gear 19 again, limiting their movement. That is, by pressing or releasing the button post 23, the first gear 17 and the second gear 19 can be contacted or locked, adjusting whether they rotate.

[0040] In one possible implementation, the telescopic rod 9 is an electric actuator. In this case, the internal structure of the second chamber 7 is the same as that of the first chamber 6. The button post 23 serves as the start switch for the electric actuator, and the power source for the electric actuator can be directly driven by the power supply of the sightseeing vehicle.

[0041] A downwardly inclined trapezoidal frame 24 is fixedly installed on the upper rear side of the seat back 4. The bottom two ends of the trapezoidal frame 24 are located above the armrest 3. When adjusting the tilt angle of the seat back 4, when the seat back 4 tilts to a certain degree, the lower part of the trapezoidal frame 24 contacts the upper side of the two armrests 3. At this time, the seat back 4 cannot be tilted further, and the trapezoidal frame 24 supports the seat back 4.

[0042] As one possible implementation, when there are no passengers riding the sightseeing vehicle or when resting at night, the seat back 4 is rotated to a horizontal position. At this time, the seat back 4 is placed flat on the seat board 1 to avoid dust accumulation. At this time, the trapezoidal frame 24 is located above the seat back 4. When it is necessary to rotate and lift the seat back 4, the trapezoidal frame 24 is used as a handle.

[0043] A round rod 2 is rotatably arranged between the two slide rods 22. The round rod 2 is located on the rear side of the seat back 4. Specifically, a connecting plate is fixedly arranged on the side of the two slide rods 22 that are close to each other, and a round rod 2 is rotatably arranged between the lower ends of the two connecting plates.

[0044] One end of the seat cushion 5 is fixedly installed on the upper rear side of the seat back 4, and the other end passes in sequence through the front side of the seat back 4, around the round rod 2, over the upper side of the seat board 1 in front of the seat back 4, around the front end of the seat board 1, and is then stored in the winding device under the seat board 1. The winding device can be a winding mechanism consisting of a roller rotatably installed under the seat board 1 and a torsion spring or a spiral spring. It has a certain winding pull on the released seat cushion. When the position of the seat back 4 is adjusted, the seat cushion 5 is released or rolled up as the seat back 4 moves, ensuring that the seat cushion 5 always covers the upper side of the seat board 1 in front of the seat back 4 and the front side of the seat back 1, ensuring the comfort of the passenger sitting in the seat.

[0045] The seat cushion 5 passes under the seat back 4, wraps around the round rod 2, and then passes under the seat back 4 again through the gap between it and the seat board 1.

[0046] In use, passengers can press button 23 as needed, the pressure plate 11 moves down, the limiting component releases the restriction on the first gear 17 and the second gear 19, allowing them to rotate. Then, the position and tilt angle of the seat back 4 can be adjusted forward and backward. After adjustment, the button 23 is released, and the pressure plate 11 moves up under the action of the tension spring 10 and the telescopic rod 9. Then, the limiting rod 15 resets under the action of gravity, and the pawl 16 is inserted between the teeth of the first gear 17 or the second gear 19 again. The first gear 17 and the second gear 19 are limited again and cannot rotate, thus fixing the seat back 4.

[0047] Meanwhile, during the adjustment of the seat back 4, the seat cushion 5 is kept covering the passenger seat to ensure comfort. After the position of the seat back 4 is adjusted, the passenger can sit down. At the same time, the upper part of the seat board 1 behind the seat back 4 can be used to prevent backpacks or other miscellaneous items from being placed on it.

[0048] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
