Description

Technical Field

[0001] This invention relates to the field of marine seat technology, and more particularly to a marine seat with multi-dimensional wire-controlled adjustment. Background Technology

[0002] During navigation, ships are constantly affected by wind, waves, and swells, causing them to rock and sway. Under extreme conditions, they may also be subjected to impact loads. Marine seats are core supporting equipment that ensures the safety and comfort of passengers. They are widely used in various warships, government vessels, and civilian ships. They need to be adapted to the multi-dimensional posture adjustment needs of passengers, while ensuring the ease of operation and structural stability under complex sea conditions. They are a core part of ship ergonomics design.

[0003] However, the existing marine seats have scattered adjustment components and mostly use mechanical hard-connection transmission methods. This makes it extremely inconvenient for passengers to adjust the seats under complex conditions of swaying and rolling. Furthermore, the mechanical hard-connection is prone to jamming and failure due to hull vibration and impact. The overall structural stability and operational reliability are low, making it unable to meet the multi-dimensional attitude adjustment needs of complex navigation conditions. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a multi-dimensional wire-controlled adjustable marine seat.

[0005] The technical solution adopted by this invention is as follows: This application provides a multi-dimensional wire-controlled adjustable marine seat, including a base, a rotating frame, a seat cushion, a backrest, a support pad, a front-to-back operating component, a rotation operating component, an angle operating component, a lifting operating component, and a sliding operating component. The base is connected to the ship by a slide rail assembly. The rotating frame is rotatably mounted on the base. A pneumatic lifting rod is provided between the rotating frame and the seat cushion. An angle adjuster is provided between the backrest and the seat cushion. The support pad is slidably mounted on the backrest via a guide rail and a slider assembly. The front-to-back, rotation, angle, lifting, and sliding operating components are all manually operated and are linked through the wire control assembly, the slide rail assembly, the rotating frame, the pneumatic lifting rod, the angle adjuster, and the guide rail and slider assembly, respectively, to realize the front-to-back, rotation, and lifting adjustment of the seat cushion, the angle adjustment of the backrest, and the height adjustment of the support pad.

[0006] In some embodiments, the front and rear operating components include a first front and rear operating component and a second front and rear operating component. The first front and rear operating component is disposed on the front side of the seat cushion, and the second front and rear operating component is disposed on the back of the backrest. Both are linked to the slide rail assembly through a first wire control assembly and are used for front and rear adjustment of the seat cushion.

[0007] In some embodiments, the slide rail assembly includes two sets of spaced upper slide rails and lower slide rails. The first wire control assembly includes a locking component corresponding to the two sets of upper slide rails and lower slide rails. The locking component includes a base, a first rotating shaft, a pull block, a first swing block, and a locking rod. The base is disposed on a base. The first rotating shaft is rotatably disposed on the base. One end of the pull block is disposed on the first rotating shaft, and the other end serves as an input end. A first torsion spring is disposed between the pull block, the first rotating shaft, and the base. One end of the locking rod is rotatably disposed on the outer wall of the inner side of the upper slide rail, and the other end is disposed on a locking plate. A first locking hole is disposed on the locking plate along the sliding direction of the slide rail assembly. A locking block is disposed on the lower slide rail corresponding to the first locking hole. An abutment plate is disposed at one end of the locking rod near the locking plate. A reset rod is disposed between the outer wall of the inner side of the upper slide rail and the abutment plate. One end of the first swing block is disposed on the first rotating shaft, and the other end abuts against the abutment plate. Under the action of the reset rod, the locking block is inserted into the first locking hole, so that the upper slide rail is locked relative to the lower slide rail. When the input end drives the pull block to rotate, it drives the first swing block to rotate, which drives the locking plate to be pressed down, so that the locking block is disengaged from the first locking hole, and the upper slide rail can slide and adjust relative to the lower slide rail.

[0008] In some embodiments, the locking rod has a protruding hinge shaft portion, and the outer wall of the inner side of the upper slide rail is provided with a hinge hole adapted to the hinge shaft portion. A limiting plate portion is provided on the locking rod at the end of the hinge shaft portion away from the locking plate portion. A first plate portion is bent on the outer wall of the inner side of the upper slide rail corresponding to the limiting plate portion, which is used to limit the limiting plate portion in the axial direction of the hinge shaft portion. A limiting groove portion is formed on the outer wall of the inner side of the upper slide rail corresponding to the locking plate portion. The limiting groove portion is located on the moving path of the locking plate portion and is used to limit the locking plate portion in both its rotational direction and in the axial direction of the hinge shaft portion.

[0009] In some embodiments, the first wire control assembly further includes a first drive line, a second drive line, a parallel cable, a third drive line, a splitter, a fourth drive line, and a fifth drive line. The parallel cable is disposed on the seat cushion, and the splitter is disposed on the base. The first and second front-to-back operating components are respectively connected to the parallel cable via the first and second drive lines. The rotating frame is vertically provided with a first cable routing channel for the third drive line to pass through. The parallel cable is connected to the splitter via the third drive line. The splitter is rotatably connected to the input ends of the pull blocks of the two locking components via the fourth and fifth drive lines.

[0010] In some embodiments, the rotating operating component is disposed on the seat cushion and is linked to the rotating frame via a second wire control assembly. The second wire control assembly includes a sixth transmission line, a mounting base, a flip lock plate, a lock post, a first spring, and a movable plate. The mounting base is provided with a movable cavity. The lock post is vertically slidably disposed in the movable cavity. The movable plate is disposed on the lock post, and the two move synchronously. The first spring is sleeved on the lock post and abuts against the bottom wall of the movable plate and the movable cavity. The flip lock plate is rotatably disposed on the mounting base. One end of the plate is connected to the sixth transmission line, and the other end is provided with a pressing plate portion that extends between the movable plate and the top wall of the movable cavity. The top of the lock post extends out of the movable cavity and is provided with a first locking portion. The rotating frame is circumferentially provided with a plurality of second locking holes. Under the action of the first spring, the first locking part extends into the second locking hole, so that the rotating frame is locked relative to the base. When the rotating operating member is activated, the flipping locking plate is driven to rotate through the sixth transmission line, which drives the pressing plate to press down the moving plate and drives the locking pin to move down, so that the first locking part exits the second locking hole, and the rotating frame can be rotated and adjusted relative to the base.

[0011] In some embodiments, the angle operating element is disposed on the seat cushion and is linked to the backrest via a third wire control assembly. The angle adjuster includes a drive shaft, and the third wire control assembly includes a swing plate and a seventh transmission line. The swing plate is disposed at one end of the drive shaft and rotates synchronously with it. The other end of the swing plate is rotatably connected to the seventh transmission line and is connected to the angle operating element via the seventh transmission line.

[0012] In some embodiments, the lifting mechanism is disposed on the seat cushion and is linked to the pneumatic lifting rod via a fourth wire control assembly. The fourth wire control assembly includes an eighth transmission line, a fixed seat, a second rotating shaft, a second swing block, a third swing block, and a first tension spring. The pneumatic lifting rod includes a trigger rod. The fixed seat is disposed on the seat cushion. The second rotating shaft is rotatably disposed on the fixed seat. One end of the second swing block is disposed on the second rotating shaft, and its other end is connected to the fixed seat via the first tension spring. One end of the third swing block is disposed on the second rotating shaft, and its other end is connected to the lifting mechanism via the eighth transmission line. A pressure seat is disposed on the second rotating shaft, and under the action of the first tension spring, the pressure seat abuts against the trigger rod. When the lifting and lowering mechanism drives the second rotating shaft to rotate via the eighth transmission line, the pressure seat presses down the trigger rod, and the seat cushion can be adjusted up and down relative to the rotating frame.

[0013] In some embodiments, the guide rail and slider assembly includes two guide rails spaced apart on the backrest, the support pad includes a headrest pad and a lumbar support pad connected to the guide rails via sliders, and the sliding operation includes a first sliding operation on the headrest pad and a second sliding operation on the lumbar support pad.

[0014] In some embodiments, a fifth wire control assembly is provided between the first sliding operation member and the head back cushion, and between the second sliding operation member and the lumbar cushion. The fifth wire control assembly includes a ninth transmission line, a moving frame, an adjusting plate, a rotating rod, and a second spring. The moving frame is connected to the guide rail via a slider. The adjusting plate is provided with a plurality of third locking holes along the length of the guide rail. The back of the head back cushion and the lumbar cushion are slidably provided with locking shafts facing the corresponding adjusting plates. The locking shaft includes a convex portion and a second locking portion. The second spring is sleeved on the locking shaft and abuts against the convex portion and the corresponding cushion. One end of the rotating rod is rotatably provided on the moving frame, and the other end is provided between the convex portion and the moving frame. The middle part of the rotating rod is connected to the corresponding sliding operation member via the ninth transmission line. Under the action of the second spring, the second locking part extends into the third locking hole, so that the corresponding backrest is locked relative to the backrest. When the corresponding sliding operation member drives the rotating rod to rotate through the ninth transmission line, it drives the second locking part to exit the third locking hole, so that the corresponding backrest can slide and adjust relative to the backrest.

[0015] The beneficial effects of this invention are as follows: This invention uses a fully linear control transmission method to replace the traditional mechanical hard connection, completely solving the problem of mechanical structure jamming under ship swaying and impact, and greatly improving structural stability and operational reliability; through the linear control components, the seat cushion can be independently adjusted in multiple dimensions, including forward and backward movement, rotation, lifting, backrest angle, and support cushion height, with each adjustment mechanism not interfering with each other. At the same time, the operating components for multi-dimensional adjustment are centrally arranged, allowing passengers to complete all-dimensional adjustments with one hand when the ship is swaying, greatly improving the convenience of operation and perfectly adapting to the needs of passenger posture adjustment and safety protection under complex sea conditions of various ships.

[0025] Existing marine seats suffer from poor stability due to the dispersed layout of various control components and the use of rigid mechanical connections. This makes it extremely inconvenient for passengers to adjust the seats when the ship is rocking, and they are also prone to mechanical jamming.

[0026] Based on the above issues, such as Figures 1 to 15 As shown, this application provides a multi-dimensional wire-controlled adjustable marine seat, including a base 1, a rotating frame 2, a seat cushion 3, a backrest 4, a support pad 5, a fore-and-aft operating component 6, a rotation operating component 7, an angle operating component 8, a lifting operating component 9, and a sliding operating component 10. The base 1 is connected to the ship by a slide rail assembly 11. The rotating frame 2 is rotatably mounted on the base 1. A pneumatic lifting rod 12 is provided between the rotating frame 2 and the seat cushion 3. An angle adjuster 13 is provided between the backrest 4 and the seat cushion 3. The support pad 5 is slidably mounted on the backrest 4 via a guide rail and a slider assembly 14. The fore-and-aft operating component 6, the rotation operating component 7, the angle operating component 8, the lifting operating component 9, and the sliding operating component 10 are all manually operated and are linked by the wire control assembly and the slide rail assembly 11, the rotating frame 2, the pneumatic lifting rod 12, the angle adjuster 13, and the guide rail and slider assembly 14, respectively, to realize the fore-and-aft, rotation, and lifting adjustment of the seat cushion 3, the angle adjustment of the backrest 4, and the height adjustment of the support pad 5. This design, by introducing multiple sets of wire-controlled components to replace the traditional rigid mechanical linkages, allows each operating component to be flexibly positioned in the area most easily accessible to the occupants. The flexible wire-controlled transmission method effectively cuts off the rigid transmission path from the ship's violent vibrations to the adjustment mechanism, fundamentally solving the technical problems of easy resonance and jamming in traditional structures, and significantly improving the smoothness of operation and the ability to ensure navigation safety.

[0027] In some embodiments, the front and rear operating components 6 include a first front and rear operating component 601 and a second front and rear operating component 602. The first front and rear operating component 601 is disposed on the front side of the seat cushion 3, and the second front and rear operating component 602 is disposed on the back of the backrest 4. Both are linked to the slide rail assembly 11 via the first wire control component 15 and are used for front and rear adjustment of the seat cushion 3. The dual-point operation design can adapt to different usage scenarios. When the passenger is in a seated position, the adjustment can be made via the first front and rear operating component 601 on the front side. When assisted by others or when the passenger is in a semi-reclined position, the adjustment can be made via the second front and rear operating component 602 on the back of the backrest 4. The operation can be completed without significant posture adjustment when the ship is rocking, greatly improving the convenience of operation.

[0028] Specifically, the slide rail assembly 11 includes two sets of spaced upper slide rails 110 and lower slide rails 111. The first wire control assembly 15 includes a locking component corresponding to the two sets of upper slide rails 110 and lower slide rails 111. The locking component includes a base 150, a first rotating shaft 151, a pull block 152, a first swing block 153, and a locking rod 154. The base 150 is mounted on the base 1. The first rotating shaft 151 is rotatably mounted on the base 150. One end of the pull block 152 is mounted on the first rotating shaft 151, and the other end serves as an input terminal 155, which is connected to the first rotating shaft 151. A first torsion spring 156 is provided between a rotating shaft 151 and a base 150. One end of the locking rod 154 is rotatably mounted on the outer wall of the inner side of the upper slide rail 110, and the other end is provided with a locking plate 157. The locking plate 157 has a plurality of first locking holes 158 along the sliding direction of the slide rail assembly 11. The lower slide rail 111 has a plurality of locking blocks 159 corresponding to the first locking holes 158. The number of first locking holes 158 and locking blocks 159 is reasonably set according to the actual adjustment requirements to ensure a tight, stable, and reliable fit when locked, while also realizing multi-position adjustment functionality. Figure 9 As shown, the locking plate 157 has three first locking holes 158 spaced apart, and the lower slide rail 111 has a series of locking blocks 159 arranged along its length.

[0029] The locking rod 154 is provided with an abutment plate 1510 at one end near the locking plate 157. The upper slide rail 110 has a reset rod 1511 between the outer wall of the inner side and the abutment plate 1510. One end of the first swing block 153 is provided on the first rotating shaft 151, and the other end of it abuts against the abutment plate 1510. The end of the first swing block 153 that abuts against the abutment plate 1510 is provided with an arc-shaped surface.

[0030] Under normal conditions, under the action of the reset rod 1511, the locking block 159 is inserted into the first locking hole 158, so that the upper slide rail 110 is locked relative to the lower slide rail 111. When the input end 155 drives the pull block 152 to rotate, it drives the first swing block 153 to rotate, which drives the locking plate part 157 to be pressed down, so that the locking block 159 is disengaged from the first locking hole 158. The upper slide rail 110 can slide and adjust relative to the lower slide rail 111. After the operating part is released, the first torsion spring 156 drives the structure to reset and complete the locking again.

[0031] Furthermore, the locking rod 154 has a protruding hinge shaft portion 1512, and the outer wall of the inner side of the upper slide rail 110 is provided with a hinge hole 1513 adapted to the hinge shaft portion 1512. The locking rod 154 has a limiting plate portion 1514 at the end of the hinge shaft portion 1512 away from the locking plate portion 157. The outer wall of the inner side of the upper slide rail 110 is bent with a first plate portion 1515 corresponding to the limiting plate portion 1514. The first plate portion 1515 limits the limiting plate portion 1514 in the axial direction of the hinge shaft portion 1512. The outer wall of the inner side of the upper slide rail 110 is formed with a limiting groove portion 1516 corresponding to the locking plate portion 157. The limiting groove portion 1516 is located on the moving path of the locking plate portion 157 and limits the locking plate portion 157 in its rotation direction and in the axial direction of the hinge shaft portion 1512. This design allows the locking rod 154 to be fixed and limited directly by the bending and stamping structure on the upper slide rail, greatly reducing the use of fasteners. At the same time, the double limiting structure can prevent the locking rod 154 from axial movement and overtravel under the impact of the hull, ensuring the accuracy and reliability of locking and unlocking actions and eliminating the risk of jamming.

[0032] Furthermore, the abutment plate 1510 is provided with an oblong hole 1517 along the sliding direction of the slide rail assembly 11. The outer wall of the inner side of the upper slide rail 110 is bent to form a first hook 1518 and a second hook 1519. One end of the reset rod 1511 is inserted and fixed in the first hook 1518 and the second hook 1519, and the other end abuts against the lower end face of the abutment plate 1510. A vertical rod 1520 is provided to extend into the oblong hole 1517 to form a sliding fit. The oblong hole 1517 can accommodate the displacement change of the abutment plate 1510 during the rotation of the locking rod 154, avoiding structural interference. At the same time, the vertical rod 1520 can radially limit the reset rod 1511, ensuring that the reset force always acts perpendicularly on the abutment plate 1510, and the reset action is stable and reliable.

[0033] Specifically, the first wire control assembly 15 further includes a first transmission line 1521, a second transmission line 1522, a parallel cable 1523, a third transmission line 1524, a splitter 1525, a fourth transmission line 1526, and a fifth transmission line 1527. The parallel cable 1523 is disposed on the seat cushion 3, and the splitter 1525 is disposed on the base 1. The first front and rear operating member 601 and the second front and rear operating member 602 are respectively connected to the parallel cable 1523 through the first transmission line 1521 and the second transmission line 1522. The rotating frame 2 is vertically provided with a first cable routing channel 1528 for the third transmission line 1524 to pass through. The parallel cable 1523 is connected to the splitter 1525 through the third transmission line 1524. The splitter 1525 is rotatably connected to the input ends 155 of the pull blocks 152 of the two locking assemblies through the fourth transmission line 1526, the fifth transmission line 1527, and the pull blocks 152 of the two locking assemblies. The parallel connector 1523 enables independent control of the two operating components, and the action of either operating component can trigger unlocking and adjustment; the splitter 1525 ensures that the locking components of the two sets of slide rail assemblies 11 are unlocked synchronously, avoiding slippage and jamming caused by unilateral locking. The entire transmission process uses plastic-coated steel wire rope transmission line, which is suitable for salt spray and humid working conditions in marine environments, wear-resistant and corrosion-resistant, and has a long service life.

[0034] In some embodiments, the rotating operating component 7 is disposed on the seat cushion 3 and is linked to the rotating frame 2 through the second wire control component 16. The second wire control component 16 includes a sixth transmission line 160, a mounting base 161, a flip locking plate 162, a locking pin 163, a first spring 164, and a moving plate 165. The mounting base 161 is provided with a movable cavity 166. The locking pin 163 is vertically slidably disposed in the movable cavity 166. The movable cavity 166 can accurately guide the sliding of the locking pin 163 and prevent the locking pin 163 from deviating or jamming during vertical movement. The moving plate 165 is disposed on the locking pin 163 and the two move synchronously. The first spring 164 is sleeved on the locking pin 163 and abuts between the moving plate 165 and the bottom wall of the movable cavity 166, which can realize the automatic reset of the locking pin 163 without the need for an additional drive structure, simplifying the overall layout.

[0035] The flip lock plate 162 is rotatably mounted on the mounting base 161. One end of the plate is connected to the sixth transmission line 160, and the other end is provided with a pressing plate 167, which extends between the moving plate 165 and the top wall of the movable cavity 166. The structural design of the pressing plate 167 can convert the rotational motion of the flip lock plate 162 into the vertical linear motion of the moving plate 165, resulting in high transmission efficiency and sensitive action response.

[0036] The top of the locking pin 163 extends out of the movable cavity 166 and is provided with a first locking part 168. The rotating frame 2 is provided with a plurality of second locking holes 169 circumferentially. Multiple locking pins 163 can also be provided to improve locking stability.

[0037] Under normal conditions, the rotating frame 2 has a second wiring channel vertically arranged for the sixth transmission line 160 to pass through. The rotating operating component 7 is connected to the flipping lock plate 162 via the sixth transmission line 160. Under the action of the first spring 164, the first locking part 168 extends into the second locking hole 169, so that the rotating frame 2 is locked relative to the base 1, which can effectively resist the impact load caused by the ship's rocking and turbulence, ensuring that the seat cushion 3 will not rotate or shake during the ship's navigation, thus improving the safety of passengers. When the rotating operating component 7 is activated, it drives the flipping lock plate 162 to rotate via the sixth transmission line 160, thereby driving the pressure plate part. The 167 presses down on the moving plate 165, causing the locking pin 163 to move downwards, so that the first locking part 168 exits the second locking hole 169. The unlocking action is smooth and without jamming, and the wire-controlled transmission method can realize remote operation, adapting to the operating needs of passengers in a seated position. The rotating frame 2 can be rotated and adjusted relative to the base 1, which can flexibly adapt to different operating orientations and improve the convenience of use. After the operating part is released, the first spring 164 drives the structure to reset and complete the circumferential locking again. The reset action is reliable and does not require manual assistance to reset, further improving the convenience of operation. At the same time, the overall structure has no redundant fasteners, which makes assembly simple and can reduce production and maintenance costs.

[0038] In some embodiments, the angle operating component 8 is disposed on the seat cushion 3 and is linked to the backrest 4 through the third wire control component 17. The angle adjuster 13 is an existing mature seat angle adjustment component, which adopts a ratchet and pawl mechanism or a damping rotating shaft structure. The core includes a drive shaft 130, a ratchet wheel, a pawl, and a reset component. The drive shaft 130 is fixedly connected to the backrest 4. The rotation of the drive shaft 130 can drive the backrest 4 to rotate synchronously, realizing stepless adjustment or multi-level adjustment of the backrest 4's tilt angle. The third wire control component 17 includes a swing plate 170 and a seventh transmission line 171. The swing plate 170 is disposed at one end of the drive shaft 130 and rotates synchronously with it. The other end of the swing plate 170 is rotatably connected to the seventh transmission line 171 and is connected to the angle operating component 8 through the seventh transmission line 171. The seventh transmission line 171 pulls the swing plate 170 to rotate, which drives the drive shaft 130 to rotate, thereby realizing the tilt angle adjustment of the backrest 4. The wire-controlled transmission can avoid the adjustment jamming caused by the vibration of the hull due to the mechanical hard connection. The operation is smooth and the adjustment accuracy is high.

[0039] In some embodiments, the lifting operation component 9 is disposed on the seat cushion 3, and is linked to the pneumatic lifting rod 12 through the fourth wire control component 18. The pneumatic lifting rod 12 is an existing mature seat lifting component, and its core consists of a cylinder, a piston rod, an internal air pressure chamber, and an unlocking trigger structure. The cylinder is fixedly installed on the rotating frame 2, and the top of the piston rod is connected to the bottom of the seat cushion 3. Under normal conditions, the internal air pressure chamber maintains a stable pressure, locking the piston rod in the current position to achieve a fixed height of the seat cushion 3. Pressing the trigger rod 120 can unlock the air pressure chamber, and the piston rod can extend and retract according to the occupant's sitting posture requirements under the action of air pressure, thereby achieving height adjustment of the seat cushion 3.

[0040] Furthermore, the fourth wire control assembly 18 includes an eighth transmission line 180, a fixed base 181, a second rotating shaft 182, a second swing block 183, a third swing block 184, and a first tension spring 185. The pneumatic lifting rod 12 includes a trigger rod 120, which is made of wear-resistant metal material and has rounded ends to reduce wear during the pressing process and extend its service life.

[0041] The fixed base 181 is mounted on the seat cushion 3. The second rotating shaft 182 is rotatably mounted on the fixed base 181. One end of the second swing block 183 is mounted on the second rotating shaft 182, and the other end is connected to the fixed base 181 via the first tension spring 185. One end of the third swing block 184 is mounted on the second rotating shaft 182, and the other end is connected to the lifting operation member 9 via the eighth transmission line 180. A pressure seat 186 is mounted on the second rotating shaft 182. Under the action of the first tension spring 185, the pressure seat 186 abuts against the trigger rod 120. When the lifting operation member 9 drives the second rotating shaft 182 to rotate via the eighth transmission line 180, the pressure seat 186 presses down on the trigger rod 120, and the seat cushion 3 can be raised and lowered relative to the rotating frame 2. After releasing the operation member, the first tension spring 185 drives the structure to reset, and the pneumatic lifting rod 12 is locked again, completing the height fixation. The entire adjustment process is smooth and responsive. The wire-controlled transmission method avoids the jamming problem of mechanical hard connections, adapts to the complex working conditions of ship rolling, and the reset action does not require manual assistance, making it easy to operate.

[0042] In some embodiments, the guide rail and slider assembly 14 includes two guide rails 140 spaced apart on the backrest 4, the support pad 5 includes a headrest pad 142 and a lumbar support pad 143 connected to the guide rails 140 via sliders 141, and the sliding operation member 10 includes a first sliding operation member 101 disposed on the headrest pad 142 and a second sliding operation member 102 disposed on the lumbar support pad 143. This allows for independent height adjustment of the headrest and lumbar support, adapting to the ergonomic needs of occupants of different heights and further enriching the adjustment dimensions of the seat.

[0043] Specifically, a fifth wire control assembly 19 is provided between the first sliding operation component 101 and the head back cushion 142, and between the second sliding operation component 102 and the lumbar cushion 143. The fifth wire control assembly 19 includes a ninth transmission line 190, a moving frame 191, an adjusting plate 192, a rotating rod 193, and a second spring 194. The moving frame 191 is connected to the guide rail via a slider. The adjusting plate 192 is provided with a plurality of third locking holes 195 along the length of the guide rail. The number of third locking holes 195 is reasonably set according to the actual adjustment requirements of the head back cushion 142 and the lumbar cushion 143. The back of the head back cushion 142 and the lumbar cushion 143 are slidably provided with locking shafts 196 facing the corresponding adjusting plate 192. The locking shaft 196 includes a convex part 197 and a second locking part 198. The end of the second locking part 198 is rounded to facilitate smooth insertion or withdrawal from the third locking hole 195 and avoid jamming.

[0044] The second spring 194 is sleeved on the locking shaft 196 and abuts against the convex portion 197 and the corresponding cushion, providing a stable elastic force. This ensures that the second locking portion 198 and the third locking hole 195 are tightly fitted under normal conditions for reliable locking, and also allows the locking shaft 196 to quickly return to its original position after unlocking, without manual assistance. One end of the rotating rod 193 is rotatably mounted on the movable frame 191, and the other end is located between the convex portion 197 and the movable frame 191. The middle part of the rotating rod 193 is connected to the corresponding sliding operating member 10 via the ninth transmission line 190.

[0045] Under normal conditions, under the action of the second spring 194, the second locking part 198 extends into the third locking hole 195, so that the corresponding backrest is locked relative to the backrest 4. When the corresponding sliding operation member 10 drives the rotating rod 193 to rotate through the ninth transmission line 190, it drives the second locking part 198 to exit the third locking hole 195, so that the corresponding backrest can slide and adjust relative to the backrest 4. After releasing the operation member, the second spring 194 drives the structure to reset and complete the height locking again.

[0046] Furthermore, a mounting plate 401 is provided on the backrest 4, and second tension springs 402 are provided on both sides of the mounting plate 401 to connect with the movable frame 191 corresponding to the lumbar support cushion 143. The second tension springs 402 can provide auxiliary support force, so that the lumbar support cushion 143 will not sag due to its own weight during adjustment, making the adjustment smoother, and at the same time, it can offset the impact load caused by the ship's turbulence.

[0047] In some embodiments, armrests 20 are rotatably provided on both sides of the lumbar support cushion 143. The armrests 20 have at least an active position and a retractable position. When in use, the armrests 20 are lowered to provide arm support, and when retracted, they can reduce space occupation and facilitate passengers to quickly enter and exit the seat.

[0048] In some embodiments, the seat cushion 3 is provided with a seat belt 21, which can restrain and protect the occupants under extreme ship operating conditions, preventing the occupants from being thrown out of the seat and causing injury.

[0049] In some embodiments, such as Figure 15 As shown, the front and rear operating components 6, rotation operating components 7, angle operating components 8, lifting operating components 9, and sliding operating components 10 all include a rotatable wrench 22 and a second torsion spring 23 for resetting the wrench 22. The wrench 22 and the corresponding transmission line are connected to drive the corresponding mechanism to move. All operating components adopt a wrench-type structure. Under the condition of ship rolling, the crew can hold and operate the wrench with one hand to complete the full-dimensional adjustment without the need for precise alignment, which greatly improves the convenience of operation.

[0050] like Figure 16 and Figure 19 As shown, this application also provides another simple type of multi-dimensional wire-controlled adjustable marine seat, which is equivalent to simply sliding a lumbar support cushion on the backrest, but also uses a sixth wire control component to control the vertical height adjustment of the lumbar support cushion.

[0051] Furthermore, the sixth wire control assembly includes a tenth transmission line 24, an adjusting rod 25, an adjusting seat 26, and a third torsion spring 27. A guide rail is provided on the backrest, and the lumbar support cushion slides in conjunction with the guide rail and the backrest via a slider. The adjusting rod 25 is disposed on the backrest along the length of the guide rail, and a first locking tooth portion 250 is provided on it along the length direction. The first locking tooth portion 250 includes a plurality of continuously and evenly arranged teeth. The adjusting seat 26 is rotatably disposed on the lumbar support cushion, and a second locking tooth portion 260 adapted to the first locking tooth portion 250 is provided on it. The adjustment seat 26 is connected to the sliding operation member 10 via the tenth transmission line 24. When the adjustment seat 26 is rotated by the sliding operation member 10, the first locking tooth 250 and the second locking tooth 260 disengage, and the height of the lumbar support cushion can be adjusted. After adjusting to the appropriate position, the sliding operation member 10 is released, and the first locking tooth 250 and the second locking tooth 260 re-lock. This structure is simpler and suitable for simple seats. At the same time, the adjustment structure with locking tooth engagement has more adjustment levels.
