Description

Technical Field

[0001] The embodiments of the present utility model relate to the technical field of pneumatic comfort systems, and particularly to a pneumatic lumbar support system and a seat. Background Art

[0002] In the existing pneumatic lumbar support system, the lumbar support airbag is usually installed on the seat by using a felt board or short fiber cotton. Among them, lugs are integrally arranged on the felt board or short fiber cotton, and the felt board or short fiber cotton is installed on the seat by winding and hanging the lugs with a steel mesh on the seat; the number and position of the assembly holes on the lugs are usually preset and determined, so that the hanging and installation position and the installation height position of the lugs on the seat are determined, that is, the equal height position of the installed felt board and the like is determined and cannot be adjusted. Moreover, when forming the felt board or short fiber cotton, holes are usually pre-drilled on the felt board or short fiber cotton according to the layout position of the lumbar support airbag. When installing the lumbar support airbag, the upper end of the lumbar support airbag is directly installed on the hole of the felt board or short fiber cotton by means of welding or snap-fastening with a four-piece buckle. In addition, for the air valve module of the pneumatic lumbar support system, holes are usually pre-drilled on the felt board or short fiber cotton when designing the corresponding felt board or short fiber cotton according to the layout position of the air valve module on the felt board or short fiber cotton. When installing the air valve module, the air valve module is directly fixedly installed on the pre-opened hole.

[0003] Therefore, after the corresponding design of the felt board or short fiber cotton of the existing pneumatic lumbar support system is basically finalized, the installation positions of the lumbar support airbag and the air valve module installed on the short fiber cotton are fixed and non-adjustable, and the applicability is low. At the same time, since the number and position of the assembly holes on the lugs are determined, the position for fixed assembly after winding on the steel mesh is also determined, and further the installation height of the overall pneumatic lumbar support system on the seat cannot be adjusted.

The terms used in this specification in the description of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0030] For the convenience of readers to understand the inventive concept of the present utility model, the following describes the specific structure of the pneumatic lumbar support system according to the embodiments of the present utility model:

[0031] Please refer to Figure 1-2, the pneumatic lumbar support system 100 of the embodiment of the present utility model includes a mounting plate 1, a lumbar support airbag 7, a gas distribution device 2 and a gas source device 8.

[0032] Among them, the gas source device 8 is connected to the lumbar support airbag 7 through the gas distribution device 2 for ventilation. For example, the gas source device 8 and the gas distribution device 2 are connected through a second air pipe 10, and the gas distribution device 2 and the lumbar support airbag 7 are connected through a first air pipe 9. During operation, the gas source device 8 supplies gas, and the gas distribution device 2 controls the inflation, deflation and pressure maintenance of the lumbar support airbag 7.

[0033] In some embodiments, the lumbar support airbag 7 can be set to at least one, such as one or more than two. Multiple lumbar support airbags 7 are arranged in a partially overlapping manner along the supporting waistline in sequence; the shape of the lumbar support airbag 7 includes but is not limited to one or more of a circle, an ellipse, a square, an arc or other irregular shapes; the material of the lumbar support airbag 7 can be selected but is not limited to thermoplastic polyurethane (TPU). Moreover, the lumbar support airbag 7 can be a single-layer airbag or a multi-layer airbag. The multi-layer airbag has multiple bag bodies, and the inflation spaces of the multiple bag bodies are connected in sequence along the inflation expansion direction. The gas distribution device 2 can be a gas valve module, which can integrally include multiple solenoid valves (such as three-way three-position solenoid valves or two-way three-position solenoid valves, etc.). When the lumbar support airbag 7 is set to multiple, each solenoid valve respectively controls the inflation, deflation and pressure maintenance of a lumbar support airbag 7. The gas source device 8 can be an air pump or an air compressor; or, the gas distribution device 2 and the gas source device 8 can be an integrated pump-valve integrated structure.

[0034] In the pneumatic lumbar support system 100 of the embodiment of the present utility model, the lumbar support airbag 7 is arranged to be installed on the mounting plate 1 to realize the support installation of the lumbar support airbag 7.

[0035] Specifically, the material of the mounting plate 1 can be selected but is not limited to short fiber cotton, felt board or plastic. Please refer to Figures 1 to 3 As shown, the mounting plate 1 is provided with a number of alternative mounting holes 11, and the alternative mounting holes 11 are holes that penetrate through the mounting plate 1 in the thickness direction. Among them, by selecting a part of the alternative mounting holes 11 from the number of alternative mounting holes 11 as the first mounting holes, and installing the lumbar support airbag 7 in the first mounting holes, the installation position of the lumbar support airbag 7 on the mounting plate 1 can be determined, so that the installation position of the lumbar support airbag 7 on the mounting plate 1 can be adjusted according to the selection of the first mounting holes, improving the adaptability of the mounting plate 1 to the type of the lumbar support airbag 7 and its installation requirements.

[0036] In an optional embodiment, the lumbar support airbag 7 can be installed in the first mounting hole of the mounting plate 1 by using a first fitting, or a part of the lumbar support airbag 7 itself can be fixed to the first mounting hole by ultrasonic welding.

[0037] For the above-mentioned first fitting, the first fitting may include one or more of buttons (such as snap buttons), rivets, bolts or fasteners. For example, the lumbar support airbag 7 is provided with a first fitting hole. The snap button includes a main button and a sub-button. A part of the main button sequentially passes through the first fitting hole and the first mounting hole and then is snapped with the sub-button to mount the lumbar support airbag 7 to the first mounting hole of the mounting plate 1; alternatively, the rivet or the fastener sequentially passes through the first fitting hole and the first mounting hole and is in interference fit with the first fitting hole and the first mounting hole to mount the lumbar support airbag 7 to the first mounting hole of the mounting plate 1; alternatively, the bolt sequentially passes through the first fitting hole and the first mounting hole and then is screwed with a nut to mount the lumbar support airbag 7 to the first mounting hole of the mounting plate 1. The cooperation of the first fitting and the first mounting hole can achieve the convenient and quick installation of the lumbar support airbag 7 on the mounting plate 1, improve the assembly efficiency of the pneumatic lumbar support system 100, and facilitate disassembly, assembly and adjustment.

[0038] The alternative mounting holes 11 on the mounting plate 1 can be set by punching with a punching machine after the mounting plate 1 is formed, or preset when the mounting plate 1 is formed. The mounting plate 1 provided with a plurality of alternative mounting holes 11 can be adapted to the installation of the lumbar support airbag 7 with different installation positions and installation method requirements, and has a wide adaptation range. In some preferred embodiments, please refer to Figure 3 again. A plurality of alternative mounting holes 11 are arranged in an array on the mounting plate 1. The array arrangement may include longitudinal and transverse staggered arrangements, so that the alternative mounting holes 11 are evenly distributed on the mounting plate 1, thereby making the alignment and positioning of the lumbar support airbag 7 during the installation through the alternative mounting holes 11 easier and more accurate, reducing the complexity and uncertainty during the installation process, and improving the installation efficiency.

[0039] In addition, there are no restrictions on the size and shape of the above-mentioned plurality of alternative mounting holes 11, as long as they can meet the installation requirements. Among them, the aperture of the alternative mounting hole 11 can be adjusted according to the sizes of the fitting and the limiting member installed in the alternative mounting hole 11. For example, it can be preferably 4 mm in aperture; a plurality of alternative mounting holes 11 arranged in an array are designed according to the mechanical properties of the mounting plate 1. For example, the hole spacing between a plurality of alternative mounting holes 11 is preferably 7 mm.

[0040] In some other embodiments, the gas distribution device 2 can be installed on the mounting plate 1 to improve the installation integration of the overall pneumatic lumbar support system 100. Among them, please refer to Figure 1 and Figure 2As shown, the lumbar support airbag 7 is installed on the first surface 1a of the mounting plate 1, and the gas distribution device 2 is installed on the second surface 1b of the mounting plate 1. The first surface 1a and the second surface 1b are two opposite surfaces in the thickness direction of the mounting plate 1, so that the space occupied by the pneumatic lumbar support system 100 in the width direction of the mounting plate 1 is more compact. In addition, when the pneumatic lumbar support system 100 is applied to a seat, the first surface 1a of the mounting plate 1 with the lumbar support airbag 7 installed faces the sitter, and the second surface 1b of the mounting plate 1 with the gas distribution device 2 installed faces away from the sitter, which can reduce the foreign body sensation when the sitter uses it, thereby improving the riding comfort.

[0041] In a preferred embodiment, by selecting a part of the alternative mounting holes 11 from several alternative mounting holes 11 as the second mounting holes and installing the gas distribution device 2 in the second mounting holes, the mounting position of the gas distribution device 2 on the mounting plate 1 is determined, so that the mounting position of the gas distribution device 2 on the mounting plate 1 can be adjusted according to the selection of the second mounting holes, improving the adaptability of the mounting plate 1 to the type and mounting requirements of the gas distribution device 2.

[0042] Among them, the part of the alternative mounting holes 11 selected as the second mounting holes can be the same as, have an intersection with, or be different from the part of the alternative mounting holes 11 used as the first mounting holes. In a preferred embodiment, considering minimizing the material cost of the mounting plate 1 as much as possible, the number of alternative mounting holes 11 will be reduced and / or the specifications of the alternative mounting holes 11 will be unified. The part of the alternative mounting holes 11 selected as the second mounting holes and the part of the alternative mounting holes 11 used as the first mounting holes will be designed to be the same / have an intersection, so that the selected alternative mounting holes 11 can be used to install both the lumbar support airbag 7 and the gas distribution device 2, simplifying the design and manufacturing process, and thus reducing the processing cost. Obviously, if necessary, the part of the alternative mounting holes 11 of the second mounting holes and the part of the alternative mounting holes 11 of the first mounting holes can be set according to the specific requirements and limitations of the connected components, and can be set in different regions. For example, the alternative mounting holes 11 of the alternative part of the first mounting holes are designed according to parameters such as the size, shape, and weight of the lumbar support airbag 7, and the alternative mounting holes 11 of the alternative part of the second mounting holes are designed according to parameters such as the size, shape, and weight of the gas distribution device 2, then the part of the alternative mounting holes 11 of the second mounting holes selected and the part of the alternative mounting holes 11 of the first mounting holes selected can be different.

[0043] It can be understood that among the several alternative mounting holes 11 provided on the mounting plate 1, only the selected alternative mounting holes 11 will be actually used as mounting holes during actual use, and the unselected alternative mounting holes 11 will be idle. The alternative mounting holes 11 can be holes of the same specification, that is, they can be used to mount the lumbar support airbag 7 or the gas distribution device 2. The alternative mounting holes 11 can also be divided into two specifications of holes, one of which is dedicated to mounting the lumbar support airbag 7, and the other is dedicated to mounting the gas distribution device 2.

[0044] In some embodiments, based on the installation stability requirements of the gas distribution device 2, the gas distribution device 2 can be installed in the second mounting hole of the mounting plate 1 by using a second fitting.

[0045] For the above-mentioned second fitting, the second fitting can include one or more of buttons (such as snap buttons), rivets, bolts or buckles. For example, the gas distribution device 2 is provided with a second assembly hole. The snap button includes a main button and a sub-button. A part of the main button sequentially passes through the second assembly hole and the second mounting hole and then is buckled with the sub-button to mount the gas distribution device 2 to the second mounting hole of the mounting plate 1; or, the rivet or buckle sequentially passes through the second assembly hole and the second mounting hole and is in interference fit with the second assembly hole and the second mounting hole to mount the gas distribution device 2 to the second mounting hole of the mounting plate 1; or, the bolt sequentially passes through the second assembly hole and the second mounting hole and then is screwed with a nut to mount the gas distribution device 2 to the second mounting hole of the mounting plate 1. Using the second fitting in cooperation with the second mounting hole can achieve the convenient and quick installation of the gas distribution device 2 on the mounting plate 1, improve the assembly efficiency of the pneumatic lumbar support system 100, and facilitate disassembly, assembly and adjustment.

[0046] In some embodiments, for the first air pipe 9 of the pneumatic lumbar support system 100 that is used to connect the lumbar support airbag 7 and the gas distribution device 2, it can be selectively fixed on the mounting plate 1.

[0047] Specifically, the pneumatic lumbar support system 100 further includes a first limiting member, which is used to select at least one of the several alternative mounting holes 11 as the third mounting hole according to the layout requirements of the first air pipe 9, and the first limiting member fixes at least a part of the first air pipe 9 in the third mounting hole (such as Figure 2As shown. Among them, the layout requirement of the first air pipe 9 is determined by the positions of the lumbar support airbag 7 and the gas distribution device 2. In addition, it is necessary to ensure the smoothness of the first air pipe 9, avoid excessive bending or kinking, and ensure smooth ventilation. The first limiting member can be a cable tie 3 or a cooperating assembly of a limiting plate 41 and a fastener 42. For example, the cable tie 3 cooperates with the third mounting hole to tie at least a part of the first air pipe 9 to the mounting plate 1, or the two ends of the fastener 42 respectively cooperate with the third mounting hole and the limiting plate 41 to fix at least a part of the first air pipe 9 to the mounting plate 1. Similarly, the selected alternative mounting hole 11 as the third mounting hole can be the same as, have an intersection with, or be different from the alternative mounting hole 11 as the first mounting hole and / or the second mounting hole, and is preferably different.

[0048] The first limiting member cooperating with the third mounting hole can achieve the convenient and quick installation of the first air pipe 9 on the mounting plate 1, improve the assembly efficiency of the pneumatic lumbar support system 100, and facilitate disassembly, assembly and adjustment.

[0049] In some embodiments, for the second air pipe 10 of the pneumatic lumbar support system 100 that is used to connect the gas distribution device 2 and the gas source device 8, it can be selectively fixed on the mounting plate 1.

[0050] Specifically, the pneumatic lumbar support system 100 further includes a second limiting member, which is used to select at least one from a number of alternative mounting holes 11 as the fourth mounting hole according to the layout requirement of the second air pipe 10, and the second limiting member fixes at least a part of the second air pipe 10 to the fourth mounting hole (as Figure 2 shown). Among them, the layout requirement of the second air pipe 10 is determined by the positions of the gas source device 8 and the gas distribution device 2. In addition, it is necessary to ensure the smoothness of the second air pipe 10, avoid excessive bending or kinking, and ensure smooth ventilation. The second limiting member can be a cable tie 3 or a cooperating assembly of a limiting plate 41 and a fastener 42. For example, the cable tie 3 cooperates with the fourth mounting hole to tie at least a part of the second air pipe 10 to the mounting plate 1, or the two ends of the fastener 42 respectively cooperate with the fourth mounting hole and the limiting plate 41 to fix at least a part of the second air pipe 10 to the mounting plate 1. Similarly, the selected alternative mounting hole 11 as the fourth mounting hole can be the same as, have an intersection with, or be different from the alternative mounting hole 11 as the first mounting hole and / or the second mounting hole and / or the third mounting hole, and is preferably different.

[0051] The second limiting member cooperating with the fourth mounting hole can achieve the convenient and quick installation of the second air pipe 10 on the mounting plate 1, improve the assembly efficiency of the pneumatic lumbar support system 100, and facilitate disassembly, assembly and adjustment.

[0052] For the above-mentioned cable tie 3, please refer to Figures 4-5, in some embodiments, the cable tie 3 includes a one-way cable tie 31. The tail of the one-way cable tie 31 has a tail positioning head 311, the middle has a middle clamping joint 312, and the head has a head clamping joint 313. When in use, the head clamping joint 313 passes through an optionally selected alternative mounting hole 11 on the mounting plate 1 and the tail positioning head 311 is limited to the alternative mounting hole 11. The head clamping joint 313 and the middle clamping joint 312 pass through another optionally selected alternative mounting hole 11 and the middle clamping joint 312 is limited to the alternative mounting hole 11. Then the head clamping joint 313 is folded back and clamped with the tail positioning head 311 to tie the air pipe to the mounting plate 1. Or, in some other embodiments, the cable tie 3 includes a two-way cable tie 32. The two ends of the two-way cable tie 32 respectively have end clamping joints 321. When in use, the end clamping joints 321 at both ends are respectively clamped on two optionally selected alternative mounting holes 11 to tie the air pipe to the mounting plate 1.

At least two riveting holes 411 can be formed on the limiting plate 41. By respectively cooperating two rivets with two spaced riveting holes 411 on the limiting plate 41 and locking them on the third mounting hole or the fourth mounting hole, at least a part of the first air pipe 9 or the second air pipe 10 is tied to the mounting plate 1.

[0054] In some embodiments, please refer to Figure 1 and Figure 2 As shown in and, the pneumatic lumbar support system 100 of the embodiment of the present invention further includes a hanging ear 5. When the pneumatic lumbar support system 100 of the embodiment of the present invention is installed on the seat, it is hung and installed on the seat through the hanging ear 5 to realize the installation of the mounting plate 1, the lumbar support air bag 7, the gas distribution device 2, etc. on the seat.

[0055] Specifically, the material of the hanging ear 5 is preferably but not limited to including short fiber cotton, felt board or plastic, and is preferably short fiber cotton or felt board with the same material as the mounting plate 1.

Similarly, the selected alternative mounting hole 11 as the fifth mounting hole can be the same as, have an intersection with, or be different from the alternative mounting hole 11 as the first mounting hole and / or the second mounting hole and / or the third mounting hole and / or the fourth mounting hole. Preferably, they are different.

[0057] For the above fixing member 6, the fixing member 6 can include one or more of a button (such as a snap button), a rivet, a bolt, or a buckle.
