[0003] This disclosure generally relates to the field of automotive seat technology, and more specifically to an airflow blocking structure for an automotive seat massage system. Background Technology

[0004] As people's demands for driving and riding comfort continue to increase, more and more car seats are equipped with both seat massage and seat ventilation functions. While enjoying the relaxing effect of massage, they can also get a good ventilation experience to reduce the stuffiness caused by sitting for a long time.

[0005] However, adding a massage function to the seat requires creating air tube slots and cartridge slots in the foam for installing massage airbags, which results in airflow loss during ventilation. Therefore, we propose an airflow blocking structure for an automotive seat massage system to solve this problem. Summary of the Invention

[0015] According to the technical solution provided in this disclosure, the receiving section is a slotted structure formed in the gas passage baffle;

[0016] The air passage baffle is connected to the air pipe through the slotted structure; when the air passage baffle is compressed, the slotted structure is compressed in the direction closer to the seat foam to block the air pipe slot.

[0017] According to the technical solution provided in this disclosure, the receiving section is a groove structure with an opening at the upper end of the gas passage baffle, and the receiving section is also connected to a snap-fit ​​section.

[0018] The receiving section has a semi-circular arc structure, and the receiving section is configured to receive the air tube and block the area below the air tube groove;

[0019] The snap-fit ​​sections are located on both sides above the receiving section and extend away from the receiving section. When the air passage baffle is under pressure, the snap-fit ​​sections are compressed towards the seat foam to block the area above the air duct groove.

[0020] According to the technical solution provided in this disclosure, the retaining wall structure body includes: a retaining wall with a snap-on mechanism;

[0021] The mounting channel is a cartridge mounting channel, which extends through the interior seat foam of the car seat along a first direction and contains a cartridge. The end of the cartridge is provided with an engaging part. The first direction is perpendicular to the bearing surface of the car seat.

[0022] When the cartridge block is subjected to pressure, the cartridge block is compressed toward the seat foam and seals the opening of the cartridge mounting slot.

[0023] According to the technical solution provided in this disclosure, the barrier structure body includes at least: an air passage barrier and a cartridge barrier; the mounting channel includes at least: an air pipe channel and a cartridge mounting channel disposed on the seat foam;

[0024] The air duct groove is disposed on the surface of the seat foam near the bearing surface, and the cassette mounting groove extends through the seat foam along a first direction, which is perpendicular to the bearing surface of the car seat.

[0025] The air passage baffle and the cartridge baffle are respectively located at the air pipe groove and the cartridge mounting groove, and are configured to mate with the air pipe and the cartridge to block the air pipe groove and the cartridge mounting groove.

[0026] According to the technical solution provided in this disclosure, the gas passage baffle is configured in conjunction with a plurality of adjacent gas pipe slots and has a plurality of spaced-apart receiving sections thereon; the receiving sections on the same gas passage baffle can be respectively connected to the gas pipes in different gas pipe slots.

[0030] In summary, this disclosure proposes an airflow blocking structure for an automotive seat massage system. The automotive seat includes a support surface configured to support a human body. A massage system is disposed on the side of the seat foam closest to the support surface, and a ventilation system is disposed on the side furthest from the support surface. The foam has several mounting channels for accommodating the massage system and several ventilation holes for ventilation. Specifically, the blocking structure includes a blocking structure body, with at least one blocking structure body disposed at each mounting channel of the massage system. The blocking structure body is an elastic structure, configured to compress towards the seat foam when subjected to pressure to block the mounting channels and prevent airflow from the ventilation system from leaking out of the mounting channels.

[0031] To add massage functions to existing seats, air duct slots and cartridge slots need to be cut into the foam to accommodate massage airbags. This makes it easy for airflow to leak at these slots during ventilation system operation, resulting in a loss of ventilation. This disclosure solves the problem by setting at least one baffle structure at each installation channel, thereby blocking airflow in each channel. Furthermore, when the baffle structure is compressed under pressure towards the seat foam, it effectively supports and positions the structure mating with it. Attached Figure Description

[0050] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0051] It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other. This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0052] To make the embodiments of this disclosure clearer and easier to understand, the application background of the embodiments of this disclosure will be introduced first.

[0053] First, referring to Figures 7, 13, and 15, the car seat 13 includes a support surface for supporting the human body. A massage system is provided on the side of the seat foam 1 near the support surface, and a ventilation system is provided on the side away from the support surface. Several mounting channels for accommodating the massage system and several ventilation holes 2 configured for ventilation are provided through the seat foam 1.

[0054] The massage system includes several airbags 10 disposed on the side of the seat foam 1 near the bearing surface. By controlling the inflation, deflation, and pressure maintenance of the airbags 10, the system can massage passengers sitting on the bearing surface according to their needs, providing a good riding experience. The ventilation system includes a fan 11 and an air bag 12 disposed on the side of the seat foam 1 away from the bearing surface and interconnected. The air bag 12 is connected to the ventilation holes 2 opened on the seat foam 1. In this way, the fan 11, the air bag 12, and the ventilation holes 2 form a connected air path. When the fan 11 is running, it can blow or suck air onto the bearing surface. The airflow direction can be compared in Figures 9 and 11. Figure 9 shows the ventilation system in suction mode, while Figure 11 shows the ventilation system in blowing mode. The working principle will not be described in detail.

[0055] In this embodiment, referring to Figures 1, 3, 5 and 7, in order to fix or meet the usage requirements of the airbag 10, the car seat massage system generally needs to open corresponding installation channels in the seat foam 1, such as air pipe channel 4 and card slot 7. However, since the massage system is mostly equipped with multiple airbags 10, it will also have a relatively large number of installation channels. Inevitably, this will also cause air leakage at the installation channels of the massage system during the operation of the ventilation system, which will result in a loss of ventilation volume of the ventilation system.

[0056] Based on the above, this disclosure provides an airflow blocking structure for an automotive seat massage system, comprising:

[0057] The retaining wall structure itself;

[0058] Each mounting channel of the massage system shall be equipped with at least one retaining wall structure.

[0059] The retaining wall structure body is an elastic structure. When subjected to pressure, the retaining wall structure body is compressed in the direction closer to the seat foam 1 to seal the mounting channel and prevent the airflow of the ventilation system from leaking from the mounting channel.

[0060] It is understandable that by setting at least one retaining wall structure body in each mounting channel, the retaining wall structure body is an elastic structure. When the retaining wall structure body is subjected to pressure transmitted from the bearing surface of the car seat 13, due to its elastic structure, the retaining wall structure body will compress towards the seat foam 1 after being compressed, and thus tightly seal the corresponding mounting channel. After the mounting channel is sealed by the retaining wall structure body, the airflow generated by the ventilation system during operation will not leak at the mounting channel, which greatly ensures the ventilation effect of the ventilation system and improves the user's riding experience.

[0061] In an optional embodiment, referring to Figures 1-7, the barrier structure body includes: an air passage barrier 3;

[0062] The installation channel is the air pipe channel 4, and the air pipe channel 4 is configured to accommodate the air pipe 5.

[0063] The air passage baffle 3 includes at least a receiving section 31; the air passage baffle 3 is connected to the air pipe 5 through the receiving section 31.

[0064] The air passage baffle 3 is configured to compress towards the seat foam 1 when subjected to pressure, and cover the air passage 5, thereby blocking the air passage groove 4.

[0065] Specifically, the air duct groove 4 is set on the surface of the seat foam 1 near the bearing surface, that is, on the side of the seat foam 1 near the passenger. This is because the air duct groove 4 is equipped with an air duct 5 configured to connect the air source and the airbag 10. The air duct 5 will connect to the airbag 10 on the upper surface of the seat foam 1. The main body of the baffle structure outside the air duct 5 is the air passage baffle 3.

[0066] Optionally, the connection between the air pipe 5 and the air passage barrier 3 can be glued or directly snapped together, and the number of air passage barrier 3 outside each air pipe 5 can be adjusted according to the actual situation.

[0067] Optionally, the air passage baffle 3 can be set separately outside the air pipe 5, or it can be integrally formed with the seat foam 1.

[0068] In an optional embodiment, the air passage baffle 3 includes at least a receiving section 31, configured to mate with the air pipe 5. When the air passage baffle 3 is under pressure, the receiving section 31, through its mating with the air pipe 5, can cover the periphery of the air pipe 5 and compress towards the seat foam 1, thereby sealing the air pipe groove 4. It is understood that, referring to Figures 2 and 4, the air passage baffle 3, after being compressed under pressure, will significantly extend beyond the air pipe groove 4, forming a tight seal on the air pipe groove 4. In addition to sealing the air pipe groove 4 to prevent airflow outward, it also provides a certain degree of support and fixation for the air pipe 5.

[0069] It should be noted that the air passage baffle 3 can be a sponge ring, a rubber ring, or a multi-layer adhesive tape wrapped around the outside of the air tube 5. All these structural forms block the air tube groove 4, so there are no special restrictions on the specific form.

[0070] In an optional embodiment, referring to Figure 8, the receiving section 31 is a slotted structure formed on the air passage baffle 3; the air passage baffle 3 is connected to the air pipe 5 through the slotted structure; when the air passage baffle 3 is compressed, the slotted structure is compressed in the direction closer to the seat foam 1 to block the air pipe slot 4.

[0071] Optionally, the slot structure can be opened in the middle of the air passage baffle 3 or in other positions, which can be adjusted according to the actual design requirements.

[0072] Understandably, in this structure, since the mounting channel is generally set on the seat foam 1, and the upper surface of the seat foam 1 is provided with a corresponding seat cover, the air passage baffle 3 will form a blockage of the airflow in the air passage 4 between the cover and the air passage 4; in addition, if the air passage baffle 3 is subjected to pressure transmitted from the bearing surface of the car seat 13, the slot structure will be pressed and will more tightly wrap around the air passage 5, supporting and fixing the air passage 5.

[0073] In an optional embodiment, referring to Figures 9-12, the receiving section 31 is a groove structure with an opening at the upper end on the air passage baffle 3, and the receiving section 31 is also connected to the snap-fit ​​section 32; the receiving section 31 is a semi-circular arc structure, and the receiving section 31 is configured to receive the air pipe 5 and block the area below the air pipe groove 4.

[0074] The snap-fit ​​section 32 is located on both sides above the receiving section 31 and extends away from the receiving section 31. When the air passage barrier 3 is under pressure, the snap-fit ​​section 32 is compressed towards the seat foam 1 to block the area above the air passage groove 4.

[0075] Optionally, the snap-fit ​​section 32 is specifically configured to snap the air tube 5 inside the receiving section 31; referring to Figures 9 and 10, the structural form of the snap-fit ​​section 32 can be a quarter-circle arc segment that bends upwards towards the semi-circular arc structure; specifically referring to Figures 11 and 12, the structural form of the snap-fit ​​section 32 can also be a straight segment extending obliquely or a barbed segment, etc., and its structure is not specifically limited here.

[0076] As can be understood from Figures 9-12, the receiving section 31 is a semi-circular arc structure that matches the specifications of the air tube 5, configured to receive the air tube 5 and seal the area below the air tube groove 4. When the air passage baffle 3 is under pressure, the snap-fit ​​section 32 compresses towards the seat foam 1, simultaneously sealing the area above the air tube groove 4. That is, with the cooperation of the receiving section 31 and the snap-fit ​​section 32, the entire air tube groove 4 is sealed, preventing airflow leakage at the air tube groove 4.

[0077] In an optional embodiment, referring to Figures 7 and 13-16, the retaining wall structure body includes: a retaining wall 6 with a snap fastener;

[0078] The mounting channel is a cartridge mounting slot 7, which runs through the seat foam 1 inside the car seat 13 along the first direction, and a cartridge 8 is arranged inside it. The end of the cartridge 8 is provided with a locking part 9; the first direction is perpendicular to the bearing surface of the car seat 13.

[0079] When the cassette block 6 is subjected to pressure, it compresses towards the seat foam 1 and seals the opening of the cassette mounting slot 7.

[0080] Specifically, a cassette 8 configured to fix the airbag 10 is arranged in the cassette mounting slot 7. The cassette 8 will fix the airbag 10 to the surface of the seat foam 1 near the bearing surface through the cassette mounting slot 7. Referring to Figures 13 and 15, there are multiple cassette mounting slots 7 distributed as needed along the second direction, and all of them penetrate the seat foam 1 along the first direction. The second direction is perpendicular to the first direction, that is, the vertical direction.

[0081] Optionally, the main body of the barrier structure outside the cartridge 8 is the cartridge barrier 6. The connection between the two can be glued or directly snapped together, and the number of cartridge barriers 6 outside each cartridge 8 can be adjusted according to the actual situation.

[0082] Understandably, the cassette block 6 is located on the side of the cassette mounting slot 7 away from the bearing surface, so it will not obstruct the operation of the airbag 10, and is configured to block the cassette mounting slot 7 to prevent air leakage. Moreover, the presence of the cassette block 6 also provides support and positioning for the cassette 8, making the connection of the cassette 8 inside the car seat 13 more stable and reducing the risk of it falling off due to shaking or displacement.

[0083] In an optional embodiment, the barrier structure body includes at least: an air passage barrier 3 and a cartridge barrier 6; the mounting channel includes at least: an air pipe channel 4 and a cartridge mounting channel 7 disposed on the seat foam 1;

[0084] The air duct groove 4 is disposed on the surface of the seat foam 1 near the bearing surface, and the cassette mounting groove 7 penetrates the seat foam 1 along the first direction, which is perpendicular to the bearing surface of the car seat 13.

[0085] The air passage barrier 3 and the cartridge barrier 6 are respectively located at the air pipe groove 4 and the cartridge mounting groove 7, and are configured to connect with the air pipe 5 and the cartridge 8 to block the air pipe groove 4 and the cartridge mounting groove 7.

[0086] It is understandable that, based on the aforementioned description of the air passage baffle 3 and the cartridge baffle 6, the baffle structure of the massage system may also include two structures: the air passage baffle 3 and the cartridge baffle 6. The air passage baffle 3 and the cartridge baffle 6 may be respectively installed at the air pipe groove 4 and the cartridge mounting groove 7, thereby connecting with the outside of the air pipe 5 and the cartridge 8 to achieve double sealing of the air pipe groove 4 and the cartridge mounting groove 7. This design can prevent airflow leakage of the ventilation system at each mounting groove to a greater extent.

[0087] In an optional embodiment, referring to Figures 1 and 2, the air passage baffle 3 is configured to cooperate with multiple adjacent air pipe slots 4, and has multiple spaced receiving sections 3 thereon; the receiving sections 31 on the same air passage baffle 3 can be connected to the air pipes 5 in different air pipe slots 4 respectively.

[0088] It is understandable that, since a car seat 13 typically has multiple airbags 10 arranged regularly in the design of a massage system, the distance between the air tube slots 4 of adjacent airbags 10 will also be relatively close. Therefore, by opening multiple spaced receiving sections 31 on an air passage baffle 3, multiple air tubes 5 can be fixed at the same time through an air passage baffle 3, thereby effectively simplifying the assembly process and improving assembly efficiency.

[0089] In an optional embodiment, referring to Figures 9 and 11, the air passage baffle 3 and the seat foam 1 are integrally molded structures, and the air passage baffle 3 is provided corresponding to the air pipe groove 4.

[0090] Since the air duct groove 4 in the seat foam 1 is planned in advance according to the design requirements of the car seat 13, the air passage baffle 3 can also be planned in advance based on the arrangement of the air duct groove 4. The air passage baffle 3 and the seat foam 1 are designed as an integral molding structure, which greatly simplifies the assembly process and effectively improves the assembly efficiency of the subsequent car seat.

[0091] In an alternative embodiment, referring to Figures 13 and 14, a cartridge barrier 6 is provided on the side of the engagement portion 9 near the cartridge mounting slot 7, configured to block the airflow flowing into the cartridge mounting slot 7.

[0092] Understandably, the engaging part 9 of the cassette 8 engages with the slot on the side of the cassette mounting groove 7 away from the bearing surface, and the other end of the cassette 8 extends into the cassette mounting groove 7 and connects to the airbag 10, thus fixing the airbag 10 to the seat foam 1; while the cassette baffle 6 can be set on the side of the engaging part 9 near the cassette mounting groove 7, thereby blocking the airflow leaking from the cassette mounting groove 7.

[0093] Optionally, multiple layers of the cassette barrier 6 can be arranged, and the specific number can be adjusted according to the actual situation.

[0094] In an alternative embodiment, referring to Figures 15 and 16, the cassette wall 6 is disposed on the side of the seat foam 1 away from the bearing surface and is located around the cassette mounting groove 7.

[0095] Understandably, the cassette block 6 can be directly set on the side of the seat foam 1 away from the bearing surface, either as an integral molded structure with the seat foam 1 or fixed to it by means of adhesive. Since it is configured to block the airflow in the cassette mounting slot 7 and must not obstruct the installation of the cassette 8, the cassette block 6 needs to be set on the periphery of the cassette mounting slot 7 to ensure that the cassette 8 can smoothly enter the cassette mounting slot 7 and connect with the airbag 10.

[0096] Alternatively, multiple layers of the cassette barrier 6 can also be arranged, and the specific number can be adjusted according to the actual situation.

[0097] In summary, this disclosure proposes an airflow blocking structure for an automotive seat massage system. By setting at least one baffle structure at the mounting channel, when the baffle structure is compressed towards the seat foam under pressure, on the one hand, since the baffle structure is an elastic structure, it will compress towards the seat foam after being compressed, thus tightly sealing the corresponding mounting channel. After the mounting channel is blocked by the baffle structure, the airflow generated by the ventilation system during operation will not leak at the mounting channel, thereby blocking the airflow of each mounting channel and greatly ensuring the ventilation effect of the ventilation system, thus improving the user's riding experience. On the other hand, it can also effectively support and position the structure mating with the baffle structure.

[0098] The above description is merely a preferred embodiment of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features disclosed in this disclosure that have similar functions.
