Abstract
Description
Technical Field
[0001] This application relates to the field of seating technology, and in particular to a foam assembly, a seat back, a seat, and a vehicle. Background Technology
[0002] Currently, with the rapid development of automobiles, users' demands for overall vehicle comfort are increasing. Among these, seat back comfort features include ventilation and massage. Typically, the seat back foam assembly is molded as a single piece, and it needs a certain thickness to meet structural strength requirements. This results in insufficient space behind the foam assembly, hindering the placement of ventilation components and lumbar support panels (for massage components) behind it. Utility Model Content
[0003] In view of this, embodiments of this application provide a foam assembly, a seat back, a seat, and a vehicle to solve the problem of insufficient space behind the foam assembly.
[0004] The first aspect of this application proposes a foam assembly, including a foam body and a mid-situ foam layer. The foam body has a notch for corresponding arrangement with a ventilation component. The mid-situ foam layer is separately formed from the foam body and is located within the notch. The mid-situ foam layer has a first ventilation hole for air to pass through the ventilation component and a receiving hole for accommodating a massage component.
[0005] The beneficial effects of the foam assembly provided in this application embodiment are as follows: By setting a notch on the foam body at the position corresponding to the ventilation component, the background foam layer is placed inside the notch during installation; that is, the background foam layer and the foam body together form the foam assembly. Since the background foam layer and the foam body are molded separately, the thickness of the background foam layer can be made thinner to solve the problem of insufficient space behind the foam assembly, which is beneficial for the arrangement of the ventilation component and the lumbar support back panel behind the foam assembly. Moreover, the softness and hardness of the background foam layer can also be designed as needed to meet comfort requirements. The foam body can meet the structural strength requirements of the foam assembly.
[0006] In some embodiments, the first ventilation hole communicates with the receiving hole.
[0007] The beneficial effects of adopting the above technical solution are that the first ventilation hole and the receiving hole are connected, which can make full use of the size of the foam layer in the scene and facilitate the setting of more first ventilation holes and receiving holes on the foam layer in the scene.
[0008] In some embodiments, the foaming layer includes a first foam portion and a second foam portion arranged at intervals, the first foam portion and the second foam portion forming the first ventilation hole and the receiving hole.
[0009] The beneficial effects of adopting the above technical solution are as follows: after the first foam part and the second foam part are connected together, the weak connection between the two is prone to breakage, which affects the aesthetics of the foam layer in the scene; however, by dividing the foam layer in the scene into the first foam part and the second foam part arranged at intervals, the flatness of the first foam part and the second foam part after cutting is guaranteed, thereby ensuring the aesthetics of the foam layer in the scene; at the same time, it can also improve the material utilization rate.
[0010] In some embodiments, two first bubble portions are provided, and any one of the first bubble portions and the second bubble portion forms the first ventilation hole and the receiving hole.
[0011] The beneficial effects of adopting the above technical solution are that the second bubble body and the two first bubble body parts can form two strip-shaped spaces, each strip-shaped space including a first ventilation hole and a receiving hole, which can improve the uniformity of ventilation and the uniformity of force during massage.
[0012] In some embodiments, the two first bubble portions have the same shape.
[0013] The advantages of adopting the above technical solution are that, since the two first bubble bodies have the same shape, there is no need to distinguish the shape of the first bubble bodies during installation; they can simply be placed on either side of the second bubble body without worrying about incorrect installation. Furthermore, the two first bubble bodies can be formed using the same set of cutting tools, reducing the manufacturing cost of the cutting tools and improving material utilization.
[0014] In some embodiments, the second bubble portion is further provided with a second ventilation hole for the air of the ventilation component to pass through.
[0015] The beneficial effects of adopting the above technical solution are that by setting a second ventilation hole on the second bubble body, the uniformity of ventilation can be further improved, thereby enhancing the comfort of the user.
[0016] In some embodiments, the foamed layer in the scene is formed by equal-thickness foaming and cutting.
[0017] The beneficial effects of adopting the above technical solution are that the foam layer in the scene is made by equal thickness foaming and cutting, which can ensure that the thickness of the foam layer in the scene is consistent after cutting, so as to ensure consistent physical properties and appearance quality.
[0018] The second aspect of this application provides a seat backrest including a lumbar support backrest, a massage component, a ventilation component, and a foam assembly as described in the first aspect, wherein the ventilation component is fixed to the lumbar support backrest, the massage component is disposed on the lumbar support backrest and located within the receiving hole, and the lumbar support backrest is fixed to the foam body.
[0019] The seat back uses any one or more embodiments of the above-described foam assembly, and therefore has the beneficial effects of the above-described embodiments, which will not be described in detail here.
[0020] In some embodiments, the ventilation component is bonded to the lumbar support back panel, and / or the in-situ foam layer is bonded to the ventilation component.
[0021] The advantages of adopting the above technical solution are that the bonding and fixing are more convenient, which helps to improve the assembly efficiency of the seat back.
[0022] In some embodiments, the seat backrest further includes a second soft foam fixed to the foam body and covering the notch, the second soft foam having a third ventilation hole corresponding to the first ventilation hole and a slit corresponding to the receiving hole.
[0023] In some embodiments, the ventilation element is a ventilation bag, and / or the massage element is a massage air bag.
[0024] A third aspect of this application provides a seat comprising a seat cushion and a seat back as described in the second aspect, the seat back being mounted on the seat cushion.
[0025] The seat adopts any one or more of the above-described embodiments of the seat back, and thus has the beneficial effects of the above-described embodiments, which will not be described in detail here.
[0026] The fourth aspect of this application proposes a means of transportation that includes a seat as described in the third aspect.
[0027] The vehicle uses any one or more of the above-described embodiments of the seat, and therefore has the beneficial effects of the above-described embodiments, which will not be described in detail here.

[0054] An embodiment of the first aspect of this application provides a foaming assembly. Please refer to... Figure 2 and Figure 3 The foam assembly 10 includes a foam body 12 and a mid-situ foam layer 11. The foam body 12 has a notch 121 for corresponding arrangement with the ventilation component 20. The mid-situ foam layer 11 is separately formed from the foam body 12 and is located within the notch 121. The mid-situ foam layer 11 has a first ventilation hole 113 for the ventilation component 20 to pass through and a receiving hole 114 for accommodating the massage component 30.
[0055] Optionally, the foam body 12 has a higher density and is relatively rigid, providing better support for the user. The foam body 12 can be made of polyurethane foam, polypropylene foam, or polyethylene foam through a high-pressure foaming process.
[0056] Optionally, the foam layer 11 has a lower density, is relatively soft, has a certain degree of elasticity, and provides good comfort. The foam layer 11 can be made of polyurethane foam, polypropylene foam, or polyethylene foam through a low-pressure foaming process.
[0057] Therefore, the combination of the foam body 12 and the background foam layer 11 can achieve a balance between support and comfort. Optionally, the thickness of the background foam layer 11 is less than or equal to the thickness of the foam body 12.
[0058] Optionally, the shape of the notch 121 is adapted to the shape of the ventilation component 20. For example, if the ventilation component 20 is rectangular, the notch 121 is rectangular accordingly; if the ventilation component 20 is oval, the notch 121 is oval accordingly. Wherein, the notch 121 is along... Figure 2 The X-direction permeable foam body 12.
[0059] The foam layer 11 and the foam body 12 are formed separately. This can be understood as the foam layer 11 and the foam body 12 being formed separately and not affecting each other. For example, the foam layer 11 can be made by low-pressure foaming process, and the foam body 12 can be made by high-pressure foaming process.
[0060] The in-situ foam layer 11 is located within the notch 121. It can be understood that the in-situ foam layer 11 can be fixed to the foam body 12 and located within the notch 121; or, the in-situ foam layer 11 can be fixed to other components (e.g., ventilation component 20) and located within the notch 121.
[0061] Optionally, the shape of the notch 121 can be adapted to the shape of the foam layer 11 in the scene. For example, if the foam layer 11 in the scene is rectangular, the notch 121 can be rectangular; if the foam layer 11 in the scene is oval, the notch 121 can be oval.
[0062] It is understood that the number of first ventilation holes 113 can be one or more. When there are multiple first ventilation holes 113, the multiple first ventilation holes 113 should be distributed on the foam layer 11 to ensure the uniformity of ventilation of the seat back 100. The first ventilation holes 113 are located along... Figure 2 The X-direction permeable foam layer 11 in the scene.
[0063] The shape of the first ventilation hole 113 is not limited in this application. For example, the shape of the first ventilation hole 113 can be circular, elliptical, oval, polygonal, or irregular. When there are multiple first ventilation holes 113, the shapes of the multiple first ventilation holes 113 can all be the same or all different, or the shapes of the multiple first ventilation holes 113 can be partially the same and partially different.
[0064] It is understood that the number of receiving holes 114 can be one or more. When there are multiple receiving holes 114, the multiple receiving holes 114 should be distributed on the foam layer 11 in the background to ensure the uniformity of massage of the seat back 100. Among them, the receiving holes 114 are along Figure 2 The X-direction permeable foam layer 11 in the scene.
[0065] The shape of the receiving hole 114 is adapted to the shape of the massage member 30. For example, if the massage member 30 is circular, the receiving hole 114 is circular; if the massage member 30 is elliptical, the receiving hole 114 is elliptical; if the massage member 30 is oval, the receiving hole 114 is oval; if the massage member 30 is polygonal, the receiving hole 114 is polygonal. When there are multiple receiving holes 114, the shapes of the multiple receiving holes 114 can all be the same, or all be different, or the shapes of the multiple receiving holes 114 can be partially the same and partially different.
[0066] The beneficial effects of the foam assembly 10 provided in this application embodiment are as follows: By providing a notch 121 on the foam body 12 at a position corresponding to the ventilation component 20, the background foam layer 11 is placed within the notch 121 during installation. That is, the background foam layer 11 and the foam body 12 together form the foam assembly 10. Since the background foam layer 11 and the foam body 12 are molded separately, the thickness of the background foam layer 11 can be made thinner to solve the problem of insufficient space behind the foam assembly 10, which is beneficial for the arrangement of the ventilation component 20 and the lumbar support back panel 40 behind the foam assembly 10. In addition, while ensuring the uniform and stable foam properties of the background foam layer 11, the softness and hardness of the background foam layer 11 can also be designed as needed to improve the problem of a small torso angle, thereby satisfying comfort. Among them, the foam body 12 can meet the structural strength requirements of the foam assembly 10.
[0067] Please refer to Figure 3 and Figure 4 In some embodiments, the first ventilation hole 113 is connected to the receiving hole 114.
[0068] Optionally, the number of massage elements 30 is multiple and they are arranged at intervals to massage multiple areas of the user's back. Correspondingly, the number of receiving holes 114 is multiple, and the first ventilation hole 113 connects two adjacent receiving holes 114.
[0069] Based on the above technical solution, the first ventilation hole 113 is connected to the receiving hole 114, which can make full use of the size of the foam layer 11 in the scene, and is conducive to setting more first ventilation holes 113 and receiving holes 114 on the foam layer 11 in the scene.
[0070] In one possible embodiment of this application, the first ventilation hole 113 and the receiving hole 114 can be processed simultaneously by cutting the foam layer 11 in one step, which has relatively high processing efficiency.
[0071] In other embodiments, the first ventilation hole 113 and the receiving hole 114 are not connected, that is, the foam layer 11 in the scene is cut twice to obtain the first ventilation hole 113 and the receiving hole 114 respectively.
[0072] Please refer to Figure 4 In some embodiments, the foaming layer 11 includes a first foam portion 111 and a second foam portion 112 arranged at intervals, the first foam portion 111 and the second foam portion 112 forming a first ventilation hole 113 and a receiving hole 114.
[0073] Among them, the first bubble body portion 111 and the second bubble body portion 112 are along Figure 4 The bubble body is arranged at intervals in the Y direction, that is, a gap 116 is left between the first bubble body 111 and the second bubble body 112.
[0074] It is understood that gaps 116 can be left at both the upper and lower ends of the first bubble part 111 and the second bubble part 112; or, gaps 116 can be left at the upper ends of the first bubble part 111 and the second bubble part 112, while a larger distance can be left at the lower ends of the first bubble part 111 and the second bubble part 112; or, gaps 116 can be left at the lower ends of the first bubble part 111 and the second bubble part 112, while a larger distance can be left at the upper ends of the first bubble part 111 and the second bubble part 112.
[0075] It is understandable that the shapes of the first bubble body 111 and the second bubble body 112 can be the same or different.
[0076] The first ventilation hole 113 formed by the first bubble body part 111 and the second bubble body part 112 may or may not be connected to the receiving hole 114.
[0077] Based on the above technical solution, by dividing the in-situ foam layer 11 into a first foam portion 111 and a second foam portion 112 arranged at intervals, the flatness of the first foam portion 111 and the second foam portion 112 at the gap 116 is ensured, thereby guaranteeing the aesthetics of the in-situ foam layer 11; at the same time, it can also improve the material utilization rate. If the first foam portion 111 and the second foam portion 112 are connected together at the gap 116, since the size of the first foam portion 111 and the second foam portion 112 at this position is small, that is, the connection between the two is relatively weak and prone to breakage, affecting the aesthetics of the in-situ foam layer 11.
[0078] In other embodiments, the gap 116 may be eliminated, meaning the first bubble portion 111 and the second bubble portion 112 are connected together.
[0079] Please refer to Figure 4 In some embodiments, two first bubble bodies 111 are provided, and any one of the first bubble bodies 111 and the second bubble body 112 forms a first ventilation hole 113 and a receiving hole 114.
[0080] This can be understood as the second bubble portion 112 being located between the two first bubble portions 111, that is, in Figure 4 In the Y direction, the two first bubble bodies 111 are located on both sides of the second bubble body 112.
[0081] There is one second bubble part 112, and the shape of the second bubble part 112 is different from the shape of the first bubble part 111.
[0082] Based on the above technical solution, the second bubble part 112 and the two first bubble parts 111 can form two strip-shaped spaces, each strip-shaped space including a first ventilation hole 113 and a receiving hole 114, which can improve the uniformity of ventilation and the uniformity of force during massage.
[0083] In other embodiments, the number of first bubble portions 111 and second bubble portions 112 may be the same, with one or more of each. For example, one of each first bubble portion 111 and second bubble portion 112 may be provided, forming a strip space; or, two of each first bubble portion 111 and second bubble portion 112 may be provided, with one first bubble portion 111 and one second bubble portion 112 forming a first strip space, and the other first bubble portion 111 and the other second bubble portion 112 forming a second strip space.
[0084] Please refer to Figure 4 In some embodiments, when there are two first bubble portions 111, the two first bubble portions 111 have the same shape.
[0085] Based on the above technical solution, since the two first bubble parts 111 have the same shape, there is no need to distinguish the shape of the first bubble parts 111 during installation. The two first bubble parts 111 can be placed directly on both sides of the second bubble part 112 without worrying about incorrect installation. Moreover, the two first bubble parts 111 can also be formed using the same set of cutting tools, reducing the manufacturing cost of the cutting tools and improving material utilization.
[0086] In other embodiments, the two first bubble portions 111 may also have different shapes.
[0087] Please refer to Figure 2 and Figure 4 In some embodiments, the second bubble body 112 is also provided with a second ventilation hole 115 for the ventilation component 20 to pass through.
[0088] It is understood that the number of second ventilation holes 115 can be one or more. When there are multiple second ventilation holes 115, they should be distributed on the foam layer 11 to ensure the uniformity of ventilation of the seat back 100. The second ventilation holes 115 are located along... Figure 2 The X-direction permeable foam layer 11 in the scene.
[0089] The shape of the second ventilation hole 115 is not limited in this application. For example, the shape of the second ventilation hole 115 can be circular, elliptical, oval, polygonal, or irregular. When there are multiple second ventilation holes 115, the shapes of the multiple second ventilation holes 115 can all be the same, or they can all be different, or the shapes of the multiple second ventilation holes 115 can be partially the same and partially different.
[0090] Optionally, there are two second ventilation holes 115. In the length direction of the second bubble body 112, the two second ventilation holes 115 are located at both ends of the second bubble body 112; one of the second ventilation holes 115 is oval in shape, and the other second ventilation hole 115 is circular in shape.
[0091] Based on the above technical solution, by providing a second ventilation hole 115 on the second bubble body 112, the uniformity of ventilation can be further improved, and the comfort of the user can be enhanced.
[0092] In other embodiments, in addition to providing a second ventilation hole 115 on the second bubble portion 112, if the size of the first bubble portion 111 meets the requirements, a second ventilation hole 115 may also be provided on the first bubble portion 111. Alternatively, the second ventilation hole 115 may not be provided on the second bubble portion 112, but may be provided on the first bubble portion 111.
[0093] Please refer to Figure 2 and Figure 3 In some embodiments, the foam layer 11 in the scene is formed by equal thickness foaming and cutting.
[0094] Equal thickness foam cutting refers to using punching equipment to cut foam sheets of equal thickness into the required shapes.
[0095] Based on the above technical solution, the foam layer 11 in the scene is formed by equal thickness foaming and cutting, which can ensure that the thickness of the foam layer 11 in the scene is consistent after cutting, so as to ensure consistent physical properties and appearance quality.
[0096] Please refer to Figure 1 and Figure 2 The second aspect of this application discloses a seat back 100. The seat back 100 includes a lumbar support back panel 40, a massage component 30, a ventilation component 20, and a foam assembly 10 as described in the first aspect. The foam assembly 10 includes a background foam layer 11 and a foam body 12. The background foam layer 11 has a first ventilation hole 113 and a receiving hole 114. The foam body 12 has a notch 121. The ventilation component 20 is fixed to the lumbar support back panel 40. The background foam layer 11 is located within the notch 121.

[0097] Among them, the lumbar support back panel 40, the ventilation component 20, and the in-situ foam layer 11 are arranged in layers, such as Figure 3 As shown.
[0098] Optionally, the lumbar support back panel 40 has an air pump on the side facing away from the ventilation component 20, and the massage component 30 is a massage air bag. The air pump is connected to the massage air bag through an air tube, and the air pump inflates and deflates the massage air bag to achieve the massage function. The massage air bag is made of a flexible material, such as rubber or polyurethane.
[0099] Optionally, the lumbar support back panel 40 is also equipped with a fan on the side facing away from the ventilation element 20, where the ventilation element 20 is a ventilation bag, such as... Figure 6 As shown, the lumbar support back panel 40 is also equipped with a vent 41, through which a fan supplies air to the ventilation bag. The ventilation bag is typically made of durable, breathable synthetic materials, such as polyurethane or polyester fiber; the ventilation bag has multiple channels to achieve uniform ventilation.
[0100] Optionally, the lumbar support backplate 40 is made of metal to meet its structural strength requirements.
[0101] The seat back 100 adopts any one or more embodiments of the foam assembly 10 described above, and thus has the beneficial effects of the above embodiments, which will not be described in detail here.
[0102] In some embodiments, the ventilation component 20 is bonded and fixed to the lumbar support back panel 40, and the in-situ foam layer 11 is bonded and fixed to the ventilation component 20.
[0103] Optionally, the ventilation component 20 is glued to the lumbar support back panel 40, and the in-situ foam layer 11 is glued to the ventilation component 20.
[0104] Based on the above solution, the bonding and fixing is relatively convenient, which helps to improve the assembly efficiency of the seat back 100.
[0105] In other embodiments, the ventilation component 20 is bonded and fixed to the lumbar support back panel 40, and the background foam layer 11 is fixed to the ventilation component 20 via a connector; or, the ventilation component 20 is fixed to the lumbar support back panel 40 via a connector, and the background foam layer 11 is bonded and fixed to the ventilation component 20; or the ventilation component 20 is fixed to the lumbar support back panel 40 via a connector, and the background foam layer 11 is fixed to the ventilation component 20 via a connector.
[0106] Please refer to Figure 2 and Figure 5 In some embodiments, the seat back 100 further includes a second soft foam 60 fixed to the foam body 12 and covering the notch 121. The second soft foam 60 has a third ventilation hole 61 corresponding to the first ventilation hole 113 and a slit 62 corresponding to the receiving hole 114.
[0107] Optionally, the size of the second soft foam 60 is larger than that of the notch 121, which can be understood as the projection of the notch 121 being within the projection of the second soft foam 60 in the X direction.
[0108] Optionally, the second soft foam 60 is bonded and fixed to the foam body 12. The second soft foam 60 has a relatively large thickness to improve the comfort of the seat back 100.
