Description

Technical Field

[0001] This application relates to the field of automotive seat technology, and more particularly to an automotive seat massage airbag assembly assembly and an automotive seat. Background Technology

[0002] In recent years, with the technological advancements in the automotive industry, seat configurations have become increasingly sophisticated. Massage systems have become a common feature in seats. Massage airbags, as an important component of these systems, are installed on the side of the seat foam closest to the body.

[0003] The massage airbag can be attached to the seat foam using a pull strap fixing structure. During installation, place the massage airbag on one side of the seat foam, pass the pull strap and restraint plate of the fixing structure through the through-hole of the seat foam, and place the restraint plate on the other side of the seat foam. Under the action of the pull strap fixing structure, the massage airbag is attached to the seat foam.

[0004] However, the openings in the seat foam cannot be made too large, making it difficult for the straps and restraint plates to pass through the holes in the seat foam, resulting in assembly difficulties. Furthermore, the length of the straps is limited to one size, making it incompatible with seat foams of different thicknesses. Utility Model Content

[0005] This application provides an assembly for a car seat massage airbag and a car seat, which enables the rapid assembly of the massage airbag and the fixing of the massage airbag to seat foam of different thicknesses.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] In a first aspect, this application provides an assembly for a car seat massage airbag, comprising:

[0008] Mounting component, one side of which is used to connect the massage air bag;

[0009] A perforated fitting is disposed on a mounting member, and at least a portion of the perforated fitting is located on the other side of the mounting member. The perforated fitting is provided with a plurality of engaging portions arranged along a first direction.

[0010] The constraint member is provided with a mating hole and a snap-fit ​​part. The snap-fit ​​part is used to engage with the meshing part to restrict the movement of the constraint member in a direction opposite to the first direction.

[0011] Among them, the perforated fitting is used to pass through the opening of the seat foam, and the restraint is used to insert and fit with the perforated fitting through the fitting hole and approach the seat foam along the first direction;

[0012] With the mounting component and the restraint component located on opposite sides of the seat foam, the snap-fit ​​part of the restraint component engages with the corresponding meshing part of the perforated fitting component to fix the massage airbag onto the seat foam.

[0013] According to the technical solution provided in the embodiments of this application, the buckle part includes an elastic cantilever, one end of which is connected to a constraint member, and at least one snap-fit ​​protrusion is provided on the elastic cantilever, the snap-fit ​​protrusion having a first snap-fit ​​surface in a first direction.

[0014] The engaging portion has a disengagement ramp and a second engagement surface in sequence in the first direction;

[0015] When the constraint moves along the first direction on the through-hole fitting, the snap-fit ​​protrusion moves along the disengagement ramp of the engagement part, and the elastic cantilever bends and deforms in the direction away from the through-hole fitting, so that the snap-fit ​​protrusion in the snap-fit ​​state can release the snap-fit.

[0016] When the restraint stops moving in the first direction on the through-hole mating part, under the reset action of the elastic cantilever, the first snapping surface of the snapping protrusion fits into the second snapping surface of the corresponding meshing part, so as to restrict the snapping protrusion from moving in the opposite direction to the first direction.

[0017] According to the technical solution provided in the embodiments of this application, the snap-fit ​​protrusion also has a mating slope in the first direction. The first snap-fit ​​surface and the mating slope are arranged sequentially along the first direction. The mating slope is used to slide in contact with the disengagement slope during the process of the snap-fit ​​protrusion moving along the disengagement slope of the engagement portion.

[0018] According to the technical solution provided in the embodiments of this application, the perforated mating part is a perforated mating plate extending along a first direction. The perforated mating plate is provided with a plurality of meshing parts arranged along the first direction. When the massage air bag is assembled, the perforated mating plate passes through the opening of the seat foam.

[0019] According to the technical solution provided in the embodiments of this application, the constraint member is provided with a limiting protrusion, and the seat foam is provided with a limiting hole that matches the shape of the limiting protrusion. The limiting protrusion is used to engage with the limiting hole to restrict the constraint member from rotating relative to the seat foam.

[0020] According to the technical solution provided in the embodiments of this application, the limiting protrusion is a triangular protrusion, a square protrusion, a rhombus protrusion, a circular protrusion, or an elliptical protrusion, and the limiting hole is a triangular hole, a square hole, a rhombus hole, a circular hole, or an elliptical hole that matches the shape of the limiting protrusion.

[0021] According to the technical solution provided in the embodiments of this application, the mounting component is a rigid mounting plate, one side of which is used to connect with the bottom of the massage air bag. When the massage air bag is inflated, the massage air bag expands in a direction away from the rigid mounting plate. The constraint component is a rigid constraint plate. When the massage air bag is fixed to the seat foam, the rigid mounting plate and the rigid constraint plate are located on both sides of the seat foam, respectively.

[0022] According to the technical solution provided in the embodiments of this application, one end of the perforated fitting is connected to the mounting part, and the perforated fitting and the mounting part are integrally formed.

[0023] According to the technical solution provided in the embodiments of this application, the massage air bag assembly also includes a fixing member, one end of the perforated fitting member is fixedly connected to the fixing member, the mounting member is provided with a through hole, and the other end of the perforated fitting member passes through the through hole of the mounting member. When the massage air bag and the mounting member are fixedly connected, the fixing member is clamped between the massage air bag and the mounting member.

[0024] A second aspect of this application provides a car seat, the car seat comprising:

[0025] Seat foaming;

[0026] Massage airbag;

[0027] The first aspect refers to the automotive seat massage airbag assembly component.

[0028] The massage airbag is connected to one side of the mounting component, which is located on the side of the seat foam closest to the human body. The perforated mating component passes through the opening of the seat foam and the mating hole of the restraint component. The buckle part of the restraint component engages with the corresponding meshing part of the perforated mating component. The restraint component is located on the side of the seat foam away from the human body.

[0029] As can be seen from the above technical solution, this application has at least the following beneficial effects:

[0030] In this application, the massage airbag is connected to the mounting component. When the massage airbag is assembled onto the seat foam, simply pass the perforated fitting through the opening in the seat foam, fit the constraint component onto the perforated fitting, and engage the buckle portion of the constraint component with the corresponding meshing portion of the perforated fitting. The constraint component and the mounting component are located on opposite sides of the seat foam. Through the pull action of the mounting component and the constraint component, the massage airbag is fixed onto the seat foam. This operation is convenient and allows for quick assembly of the massage airbag onto the seat foam. Furthermore, the buckle portion of the constraint component can engage with any one of the multiple meshing portions arranged along the first direction on the perforated fitting, allowing the massage airbag to be assembled onto seat foams of different thicknesses. Moreover, both the mounting component and the constraint component can be rigid plate structures, which strengthens the support of the seat foam for the massage airbag during inflation, making the seat foam less prone to denting under the pressure of the massage airbag and increasing the lifting height of the massage airbag along the direction away from the seat foam.

Detailed Implementation

[0048] The terms "first," "second," and "third," etc., used in this application specification and accompanying drawings are used to distinguish different objects, not to limit a specific order.

[0049] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0050] To ensure clarity and conciseness in the description of the following embodiments, a brief introduction to the related technologies is given first:

[0051] In recent years, with the technological advancements in the automotive industry, seat configurations have become increasingly sophisticated. Massage systems have become a common feature in seats. Massage airbags, as a key component of these systems, are installed on the side of the seat foam closest to the body. By inflating or deflating the massage airbags, they expand or contract, providing a massage effect to the body.

[0052] During assembly, the massage airbags need to be installed on the seat foam surface. Common methods include attaching the airbags to the foam with double-sided tape or securing them to pre-embedded steel wires within the foam using hooks. However, hooks and double-sided tape attachments carry the risk of insecure fixation; under vector pressure, the massage airbags may shift to the left or right.

[0053] Massage airbags can also be attached to the seat foam by passing through the openings in the foam using a strap fixing structure. However, the openings in the seat foam cannot be made too large, making it difficult for the strap and restraint plate of the strap fixing structure to pass through the openings, thus affecting assembly efficiency. Furthermore, the length of the strap is limited to one size, making it incompatible with seat foams of different thicknesses. Additionally, the seat foam is a sponge structure, and since the massage airbag is mounted on the sponge, it will sink into the sponge when inflated due to the softness of the sponge, reducing the massage airbag's travel distance.

[0054] In view of this, this application provides a massage airbag assembly assembly and a car seat. The car seat is installed on a car, and the massage airbag is connected to the mounting component. When the massage airbag is assembled into the seat foam of the car seat, it is only necessary to pass the perforated fitting through the opening of the seat foam, fit the constraint component onto the perforated fitting, and engage the buckle portion of the constraint component with the corresponding meshing portion of the perforated fitting. The constraint component and the mounting component are located on opposite sides of the seat foam. Through the pull action of the mounting component and the constraint component, the massage airbag is fixed to the seat foam. The device is easy to use and can quickly assemble the massage airbag onto the seat foam. Moreover, the buckle of the restraint can engage with any of the multiple meshing parts arranged along the first direction on the perforated mating part, allowing the massage airbag to be assembled onto seat foam of different thicknesses. Furthermore, both the mounting part and the restraint can be rigid plate-like structures, which strengthens the support of the seat foam for the massage airbag when it is inflated, making the seat foam less prone to denting under the pressure of the massage airbag and increasing the lifting height of the massage airbag along the direction away from the seat foam.

[0055] The first aspect of this application provides an automotive seat massage airbag assembly 10, such as... Figure 1-6 As shown, the assembly includes a mounting component 1, a perforated fitting component 2, and a restraining component 3. One side of the mounting component 1 is used to connect the massage air bag 20. The perforated fitting component 2 is disposed on the mounting component 1, and at least a portion of the perforated fitting component 2 is located on the other side of the mounting component 1. The perforated fitting component 2 is provided with a plurality of engaging portions 21 arranged along the first direction X. The restraining component 3 is provided with a mating hole 31 and a snap-fit ​​portion 32. The snap-fit ​​portion 32 is used to engage with the engaging portion 21 to restrict the restraining component 3 from moving in a direction opposite to the first direction X.

[0056] When assembling the massage airbag 20 onto the seat foam 30 using assembly components, such as Figure 7-10As shown, the massage airbag 20 is connected to one side of the mounting piece 1, and the perforated fitting piece 2 located on the other side of the mounting piece 1 passes through the opening of the seat foam 30 from the side of the seat foam 30 facing the human body; the restraint piece 3 is fitted onto the perforated fitting piece 2 from the side of the seat foam 30 away from the human body, specifically by inserting it into the perforated fitting piece 2 through the fitting hole 31, and then the restraint piece 3 is brought close to the seat foam 30 along the first direction X; with the mounting piece 1 and the restraint piece 3 located on opposite sides of the seat foam 30, the snap-fit ​​part 32 of the restraint piece 3 engages with the corresponding meshing part 21 of the perforated fitting piece 2, thus fixing the massage airbag 20 to the seat foam 30.

[0057] Specifically, the perforated fitting 2 is provided with a plurality of engaging portions 21 arranged along the first direction X. The latching portion 32 of the constraint member 3 will engage with any one of the plurality of engaging portions 21. For example, when the latching portion 32 engages with one of the engaging portions 21, the engaging portion 21 restricts the movement of the latching portion 32 along the second direction Y, which is the opposite direction to the first direction X. When the engaging portion 21 does not restrict the movement of the latching portion 32 along the first direction X, the latching portion 32 can move along the first direction X to the position of the next engaging portion 21 and engage with the next engaging portion. The part 21 engages with the seat foam 3, so the constraint 3 can move along the first direction X on the perforated fitting part 2 until the mounting part 1 and the constraint 3 are respectively located on both sides of the seat foam 30. Generally, the mounting part 1 and the constraint 3 are respectively attached to both sides of the seat foam 30. At this time, the buckle part 32 of the constraint 3 engages with the corresponding meshing part 21 on the perforated fitting part 2, and a pulling effect is generated between the mounting part 1 and the constraint 3, so that the mounting part 1 and the constraint 3 are kept in the state of being located on both sides of the seat foam 30, thereby making the massage air bag 20 stably fixed on the seat foam 30.

[0058] The car seat massage airbag assembly 10 provided in this embodiment only requires connecting the massage airbag 20 to one side of the mounting part 1, passing the perforated fitting 2 on the other side of the mounting part 1 through the opening of the seat foam 30, and then fitting the restraint 3 onto the perforated fitting 2 from the end away from the mounting part 1, and moving the restraint 3 along the first direction X until the mounting part 1 and the restraint 3 are respectively located on both sides of the seat foam 30, and the snap-fit ​​part 32 of the restraint 3 engages with the engaging part 21 on the perforated fitting 2. With this, the assembly operation of fixing the massage airbag 20 to the seat foam 30 is completed. During the process, only the perforated fitting part 2 passes through the opening of the seat foam 30, so there is no difficulty in the perforation operation, which improves the assembly efficiency. Moreover, the snap-fit ​​part 32 of the constraint part 3 can engage with any one of the multiple engaging parts 21 arranged along the first direction X on the perforated fitting part 2, so that the massage airbag 20 can be assembled onto seat foam 30 of different thicknesses to be compatible with seat foam 30 of various thicknesses.

[0059] After the massage air bag 20 is assembled, the portion of the perforated fitting 2 that extends beyond the constraint 3 can be appropriately cut off.

[0060] In one specific embodiment, such as Figure 6 As shown, the latching part 32 includes an elastic cantilever 321, one end of which is connected to the constraint member 3. The elastic cantilever 321 is provided with at least one latching protrusion 322, and the latching protrusion 322 has a first latching surface 323 in the first direction X. The engaging part 21 has a disengaging inclined surface 211 and a second latching surface 212 in the first direction X.

[0061] When the constraint member 3 moves along the first direction X on the perforated fitting member 2, the locking protrusion 322 moves along the disengagement slope 211 of the engagement part 21, and the elastic cantilever 321 bends and deforms in a direction away from the perforated fitting member 2, so that the locking protrusion 322 and the engagement part 21 in the engagement state are released from the locking engagement; when the constraint member 3 stops moving along the first direction X on the perforated fitting member 2, under the reset action of the elastic cantilever 321, the first locking surface 323 of the locking protrusion 322 is attached to the second locking surface 212 of the corresponding engagement part 21, so as to restrict the locking protrusion 322 from moving in a direction opposite to the first direction X.

[0062] For example Figure 6 As shown, the elastic cantilever 321 is provided with three snap-fit ​​protrusions 322 arranged along the first direction X, and the meshing part 21 is a meshing protrusion provided on the perforated fitting 2; Figure 6 The three locking protrusions 322 are respectively engaged with their corresponding meshing protrusions. Specifically, the first locking surface 323 of each locking protrusion 322 is in contact with the second locking surface 212 of the corresponding meshing protrusion to restrict the movement of the locking protrusion 322 along the second direction Y. When the constraint member 3 moves along the first direction X, the first locking surface 323 of each of the three locking protrusions 322 disengages from the second locking surface 212 of its original corresponding meshing protrusion, and each of the three locking protrusions 322 moves along the next direction X. The movement of the disengaging ramp 211 of the engagement protrusion causes the elastic cantilever 321 to bend and deform in the direction away from the through-hole fitting 2. At this time, the three locking protrusions 322 are lifted up, and all three locking protrusions 322 are released from the locking engagement. When each of the three locking protrusions 322 moves to one side of the second locking surface 212 of the next engagement protrusion in the first direction X, under the reset action of the elastic cantilever 321, the first locking surface 323 of each of the three locking protrusions 322 is in contact with the second locking surface 212 of the next engagement protrusion.

[0063] In this embodiment, the elastic deformation of the elastic cantilever 321 causes the snap-fit ​​protrusion 322 to disengage from the original corresponding engagement part 21; the elastic restoring force of the elastic cantilever 321 causes the snap-fit ​​protrusion 322 to engage with the next engagement part 21; when the constraint member 3 moves along the first direction X, the snap-fit ​​part 32 automatically engages or disengages with the corresponding engagement part 21, facilitating assembly operations. Furthermore, the first snap-fit ​​surface 323 of the snap-fit ​​protrusion 322 fits against the second snap-fit ​​surface 212 of the engagement part 21, ensuring the reliability of the snap-fit ​​engagement.

[0064] Specifically, the snap-fit ​​protrusion 322 also has a mating slope 324 in the first direction X. The first snap-fit ​​surface 323 and the mating slope 324 are arranged sequentially along the first direction X. The mating slope 324 is used to slide in contact with the disengagement slope 211 during the process of the snap-fit ​​protrusion 322 moving along the disengagement slope 211 of the engagement portion 21.

[0065] For example Figure 6 As shown, during the movement of the constraint member 3 along the first direction X, the mating slope 324 of each snap-fit ​​protrusion 322 slides into contact with the disengagement slope 211 of the next engaging protrusion in the first direction X, making the snap-fit ​​protrusion 322 more easily lifted, and thus making the snap-fit ​​protrusion 322 more easily disengage.

[0066] For example Figure 6 As shown, the snap-fit ​​protrusion 322 is a triangular protrusion, and the engagement protrusion is a trapezoidal protrusion.

[0067] In one specific embodiment, the perforated mating member 2 is a perforated mating plate extending along the first direction X. The perforated mating plate is provided with a plurality of engaging portions 21 arranged along the first direction X. When the massage air bag 20 is assembled, the perforated mating plate passes through the opening of the seat foam 30.

[0068] In this embodiment, the perforated mating part 2 is a perforated mating plate. The perforated mating plate has a certain hardness and extends along the first direction X. When the massage air bag 20 is assembled, it is easier for the perforated mating plate to pass through the opening of the seat foam 30. The constraint part 3 is also easier to move on the perforated mating plate, which further improves the assembly efficiency.

[0069] To facilitate the fitting of constraint 3 onto the perforated mating plate, such as Figure 2 As shown, the end of the perforated mating plate away from the mounting part 1 is the through part 22, and the surface of the through part 22 is a plane.

[0070] When the perforated mating plate mates with the constraint member 3, the through portion 22 of the perforated mating plate passes through the mating hole 31 of the constraint member 3. Since the surface of the through portion 22 is flat, that is, the meshing portion 21 is not provided on the through portion 22, the through portion 22 is less likely to interfere with the mating hole 31 and the snap-fit ​​portion 32 when passing through the mating hole 31 of the constraint member 3, thereby making it easier for the constraint member 3 to be fitted onto the perforated mating plate.

[0071] In one specific embodiment, such as Figure 6 As shown, the engaging part 21 is an engaging protrusion provided on one side of the perforated mating part 2. One end of the snap-fit ​​part 32 is connected to the constraint member 3, and the snap-fit ​​part 32 is located on one side of the mating hole 31 of the constraint member 3. The snap-fit ​​part 32 is used to engage with the engaging protrusion.

[0072] In another specific embodiment, the engaging part 21 is an engaging groove formed on the surface of one side of the perforated mating part 2, one end of the snap-fit ​​part 32 is connected to the constraint part 3, and the snap-fit ​​part 32 is located on one side of the mating hole 31 of the constraint part 3. The snap-fit ​​part 32 is used to engage with the engaging groove.

[0073] To improve the installation reliability of constraint 3, such as Figure 3 , Figure 6 , Figure 10 As shown, the constraint member 3 is provided with a limiting protrusion 33, and the seat foam 30 is provided with a limiting hole 301 that matches the shape of the limiting protrusion 33. The limiting protrusion 33 is used to engage with the limiting hole 301 to restrict the constraint member 3 from rotating relative to the seat foam 30.

[0074] During the assembly of the massage airbag 20, the constraint member 3 is brought close to the seat foam 30 along the first direction X, and the limiting protrusion 33 of the constraint member 3 is inserted into the limiting hole 301 of the seat foam 30. At this time, under the cooperation of the limiting protrusion 33 and the limiting hole 301, the constraint member 3 is restricted from rotating relative to the seat foam 30, so that the snap-fit ​​part 32 of the constraint member 3 can reliably engage with the meshing part 21 on the perforated fitting part 2, thereby improving the assembly reliability of the massage airbag 20; moreover, the cooperation between the limiting protrusion 33 and the limiting hole 301 also realizes the positioning and installation of the constraint member 3 on the seat foam 30.

[0075] In addition, the seat foam 30 has an installation groove on the side closest to the human body. The massage air bag 20 and the mounting piece 1 are installed in the installation groove to prevent the massage air bag 20 from moving and to achieve the positioning and installation of the massage air bag 20 on the seat foam 30.

[0076] Specifically, the limiting protrusion 33 is a triangular protrusion, a square protrusion, a rhombus protrusion, a circular protrusion, or an elliptical protrusion, and the limiting hole 301 is a triangular hole, a square hole, a rhombus hole, a circular hole, or an elliptical hole that matches the shape of the limiting protrusion 33.

[0077] For example Figure 10 In the embodiment shown, the limiting protrusion 33 is a square protrusion, and the limiting hole 301 is a square blind hole. The square protrusion and the square blind hole are interlocked to indicate that the constraint member 3 rotates relative to the seat foam 30. Moreover, in combination with Figure 3 The square protrusion has a hollow structure. One end of the square protrusion is connected to the constraint member 3. The buckle part 32 and the mating hole 31 are located inside the square protrusion.

[0078] To increase the inflation stroke of the massage airbag 20, in one specific embodiment, the mounting member 1 is a rigid mounting plate, one side of which is used to connect with the bottom of the massage airbag 20. When the massage airbag 20 is inflated, it expands in a direction away from the rigid mounting plate. The constraint member 3 is a rigid constraint plate. When the massage airbag 20 is fixed to the seat foam 30, the rigid mounting plate and the rigid constraint plate are located on both sides of the seat foam 30, respectively.

[0079] refer to Figure 7 , Figure 10 In the illustrated embodiment, when the massage airbag 20 is fixed to the seat foam 30, specifically, the massage airbag 20 is connected to one side of the mounting member 1, and the rigid mounting plate is located on the side of the seat foam 30 closest to the human body. Specifically, the rigid mounting plate can be attached to the side of the seat foam 30 closest to the human body. The perforated fitting member 2 passes through the opening of the seat foam 30 and the fitting hole 31 of the rigid constraint plate. The snap-fit ​​part 32 of the rigid constraint plate is engaged with the corresponding meshing part 21 of the perforated fitting member 2. The rigid constraint plate is located on the side of the seat foam 30 away from the human body. Specifically, the rigid constraint plate can be attached to the side of the seat foam 30 away from the human body.

[0080] The rigid mounting plate and rigid restraint plate are located on both sides of the seat foam 30, which hardens the part of the seat foam 30 where the massage air bag 20 is installed, improves the support of the seat foam 30 for the massage air bag 20, and makes the seat foam 30 less likely to dent under the pressure of the massage air bag 20. This can increase the lifting height of the massage air bag 20 in the direction away from the seat foam 30, thereby ensuring the inflation stroke of the massage air bag 20.

[0081] like Figure 15 As shown in the embodiment of this application, when the massage airbag 20 is inflated, the lifting height of the massage airbag 20 is h2; in the prior art, when the massage airbag is inflated, the lifting height is h1; where h2 > h1. It can be seen that in the embodiment of this application, the part of the seat foam 30 where the massage airbag 20 is installed is hardened, which improves the supporting effect of the seat foam 30 on the massage airbag 20 and effectively increases the lifting height of the massage airbag 20 in the direction away from the seat foam 30.
