Description

[Technical Field]

[0001] This utility model relates to the field of seat technology, and in particular to seat support cushions and seats. [Background Technology]

[0002] Existing seats generally include a seat support cushion, which provides flexible support to the human body to improve user comfort. Existing seat support cushions typically include a support core and a flexible covering layer wrapped around the outside of the support core. The support core has a human body support surface, and part of the covering layer is attached to the human body support surface by sewing. To increase heat dissipation and aesthetics, the portion of the existing covering layer attached to the human body support surface usually has a decorative seam. During sewing, the needle and thread need to pass through the covering layer and the support core. By pulling the covering layer, a recessed decorative seam can be formed. This method of forming a decorative seam not only increases the sewing difficulty but also leads to low processing efficiency of the seat support cushion and inconvenience in removing the covering layer. [Utility Model Content]

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a seat support pad and seat, which can effectively improve the processing efficiency of the seat support pad and seat to reduce manufacturing costs, and facilitate the removal of the cover layer.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] Seat support cushion, including:

[0006] The inner core is supported and has a surface that supports the human body.

[0007] A flexible covering layer is attached at least to the human body support surface;

[0008] The human body support surface is partially concave to form a first recessed portion. A first connector is disposed in the first recessed portion. The covering layer includes an inner side facing the inner core of the support and an outer side facing away from the inner core of the support. A second connector is disposed on the inner side of the covering layer. The first connector and the second connector are detachably connected and pull the covering layer into the depth of the first recessed portion, so that the outer side of the covering layer outlines a corresponding groove structure.

[0009] Using the above technical solution, during the assembly of the seat support cushion, a portion of the covering layer is first placed on the human body support surface. Then, the corresponding portion of the covering layer is pressed deeper into the first recess, connecting the first and second connectors. This pulls the covering layer deeper into the first recess, outlining a corresponding groove structure on the outer side of the covering layer. This groove structure forms the decorative seam of the seat support cushion, eliminating the need for sewing. It also achieves the connection between the covering layer and the human body support surface, ensuring the reliability of the connection between the covering layer and the support core. Compared to sewing methods, this invention's technical solution allows for higher assembly efficiency and lower manufacturing costs for the seat support cushion and seat. Furthermore, since the first and second connectors are detachably connected, the covering layer can be easily removed for replacement or cleaning.

[0010] In the aforementioned seat support cushion, at least a portion of the covering layer is tensioned through the connection of the first and second connectors to conform to the shape of the human body support surface. This design allows the portion of the covering layer that covers the human body support surface to adapt to and conform to the shape of the human body support surface, thus avoiding wrinkles and ensuring the aesthetics of the side of the seat support cushion that supports the human body.

[0011] In the aforementioned seat support cushion, the first recess extends linearly. This design increases the length of the groove structure, thereby increasing its heat dissipation area and improving the heat dissipation effect of the decorative seam. Furthermore, the linear extension design also reduces the processing difficulty of the first recess.

[0012] In the aforementioned seat support cushion, at least two linearly extending first recesses are spaced apart or intersecting on the human body support surface. This design, by increasing the number of first recesses, can further increase the heat dissipation area and improve the heat dissipation effect; in addition, depending on the appearance requirements, the at least two linearly extending first recesses can be designed to be intersecting or spaced apart, enhancing the aesthetic diversity of the seat support cushion.

[0013] In the aforementioned seat support cushion, one of the first and second connectors is a Velcro fastener and the other is a Velcro fastener; alternatively, one of the first and second connectors is a female snap fastener and the other is a male snap fastener; or alternatively, the first and second connectors are magnetically attracted to each other. This design not only facilitates the procurement or processing of the first and second connectors, reducing their cost, but also reduces the difficulty of connecting and disassembling them, thereby improving assembly efficiency and the disassembly experience.

[0014] In the aforementioned seat support cushion, a second recess is formed by a partial indentation of the human body support surface of the support core. This second recess is separated from the first recess and is covered by the covering layer. This design provides space for deformation of the portion of the support core surrounding the second recess, making that portion more easily deformable. The more second recesses there are, the softer the support core becomes. Therefore, by adjusting the number and distribution of the second recesses, the firmness of the support core can be adjusted, thereby increasing user comfort. Simultaneously, the design of the second recess reduces the contact area between the human body support surface and the body, improving heat dissipation.

[0015] The aforementioned seat support cushion also includes a cushioning spring, which is either encased in the support core or supported on the side of the support core facing away from the human body. This design improves the support of the seat support cushion for the user and allows for adaptive adjustment via the cushioning spring, thereby achieving a close fit to the curves of the human body and enhancing user comfort; furthermore, it extends the service life of the support core.

[0016] In the aforementioned seat support cushion, the support core is an elastomer made of sponge or latex. This design allows the support core to provide both support and elasticity, improving user comfort. Furthermore, it facilitates the procurement and processing of the support core, thereby reducing its cost.

[0017] In the aforementioned seat support cushion, the covering layer is a composite layer of one or a combination of a fiber fabric layer, a leather layer, or a combination thereof.

[0018] Furthermore, this utility model also discloses a seat, including a seat frame and a backrest frame, wherein at least one of the seat frame and the backrest frame is equipped with a seat support pad as described in any of the above-mentioned technical solutions. By adopting the seat support pad of the above-mentioned technical solutions, the processing efficiency of the seat can be improved, thereby reducing the manufacturing cost of the seat; at the same time, it also facilitates the removal and installation of the cover layer, improving the user experience.

[0019] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. [Attached Image Description]

Detailed Implementation Methods

[0027] This utility model provides a seat support cushion, including:

[0028] The inner core is supported and has a surface that supports the human body.

[0029] A flexible covering layer is attached at least to the human body support surface;

[0030] The human body support surface is partially concave to form a first recessed portion. A first connector is disposed in the first recessed portion. The covering layer includes an inner side facing the inner core of the support and an outer side facing away from the inner core of the support. A second connector is disposed on the inner side of the covering layer. The first connector and the second connector are detachably connected and pull the covering layer into the depth of the first recessed portion, so that the outer side of the covering layer outlines a corresponding groove structure.

[0031] Using the above technical solution, during the assembly of the seat support cushion, a portion of the covering layer is first placed on the human body support surface. Then, the corresponding portion of the covering layer is pressed deeper into the first recess, connecting the first and second connectors. This pulls the covering layer deeper into the first recess, outlining a corresponding groove structure on the outer side of the covering layer. This groove structure forms the decorative seam of the seat support cushion, eliminating the need for sewing. It also achieves the connection between the covering layer and the human body support surface, ensuring the reliability of the connection between the covering layer and the support core. Compared to sewing methods, this invention's technical solution allows for higher assembly efficiency and lower manufacturing costs for the seat support cushion and seat. Furthermore, since the first and second connectors are detachably connected, the covering layer can be easily removed for replacement or cleaning.

[0033] Example 1

[0034] like Figures 1 to 4 As shown, the seat support cushion 100 in this embodiment includes a support core 110 and a flexible covering layer 120. The support core 110 has a human body support surface 111 that contacts and supports the human body. The covering layer 120 is a composite layer of one or a combination of fiber fabric, leather, or other materials, such as cotton, linen, blended fabric, fleece, genuine leather, artificial leather, or a combination thereof. The covering layer 120 is attached to at least the human body support surface 111, and in this embodiment, the covering layer 120 covers the entire outer side of the support core 110. The human body support surface 111 is partially concave to form a first recess 112. A first connector 130 is disposed in the first recess 112. The cover layer 120 includes an inner side facing the support core 110 and an outer side facing away from the support core 110. A second connector 140 is disposed on the inner side of the cover layer 120. The first connector 130 and the second connector 140 are detachably connected and pull the cover layer 120 into the depth of the first recess 112, so that the outer side of the cover layer 120 outlines a corresponding groove structure.

[0035] In this embodiment, when assembling the seat support cushion 100, a portion of the covering layer 120 is first placed on the human body support surface 111. Then, the corresponding portion of the covering layer 120 is pressed into the depth of the first recess 112, connecting the first connector 130 and the second connector 140. This pulls the covering layer 120 into the depth of the first recess 112, outlining a corresponding groove structure on the outer side of the covering layer 120. The groove structure forms the decorative seam 001 of the seat support cushion 100. Thus, the decorative seam can be processed without sewing, and the connection between the covering layer 120 and the human body support surface 111 is also achieved, ensuring the reliability of the connection between the covering layer 120 and the support core 110. Compared with the sewing method, this embodiment can make the assembly efficiency of the seat support cushion 100 and the seat higher and the manufacturing cost lower. In addition, since the first connector 130 and the second connector 140 are detachably connected, the covering layer 120 can also be easily removed for replacement or cleaning.

[0036] Specifically, in this embodiment, one of the first connector 130 and the second connector 140 is a Velcro fastener, and the other is a Velcro fastener. The first connector 130 is fixed to the bottom wall of the first recess 112 by adhesive or sewing, and the second connector 140 is fixed to the inner side of the covering layer 120 by sewing or adhesive. The connection between the Velcro fastener and the Velcro fastener allows at least a portion of the covering layer 120 to be stretched to conform to the shape of the human body support surface 111. This ensures that the portion of the covering layer 120 covering the human body support surface 111 can fit and conform to the shape of the human body support surface 111, avoiding wrinkles and thus ensuring seat support. The pad 100 supports the aesthetics of the human body on one side; it also allows the outer side of the cover layer 120 to outline the corresponding groove structure; in addition, since both the Velcro tabs and the Velcro female tabs are commonly used accessories, it is convenient to purchase or process the first connector 130 and the second connector 140, thereby reducing the cost of the first connector 130 and the second connector 140; finally, during disassembly, simply pulling the cover layer 120 can separate the Velcro tabs and the Velcro female tabs, thereby disassembling the first connector 130 and the second connector 140, which reduces the difficulty of connecting and disassembling the first connector 130 and the second connector 140, thereby improving assembly efficiency and disassembly experience.

[0037] In order to make the support core 110 both supportive and elastic, the support core 110 in this embodiment is an elastomer made of sponge or latex. Sponge or latex is a commonly used core material, which also facilitates the procurement or processing of the support core 110 and reduces the cost of the support core 110.

[0038] In this embodiment, the first recess 112 extends linearly. The first recess 112 can extend in a straight line or a curve, that is, the first recess 112 is a long groove. At this time, the length of the first connector 130 matches the length of the first recess 112, and the length of the corresponding second connector 140 matches the length of the first connector 130. This can improve the connection reliability between the cover layer 120 located inside the first recess 112 and the first recess 112, thereby ensuring the stability of the decorative seam 001 after its formation. In addition, the linear extension of the first recess 112 can also increase the length of the groove structure to increase the heat dissipation area of ​​the groove structure, thereby improving the heat dissipation effect of the decorative seam 001. Finally, the linear extension design can also reduce the processing difficulty of the first recess 112.

[0039] It is understood that in other embodiments of this utility model, one of the first connector and the second connector may be provided in multiples at intervals along the length direction of the first recess, and the other may be a whole strip of Velcro provided along the length of the first recess; or, both the first connector and the second connector may be provided in multiples at intervals along the length direction of the first recess, and the first connector and the second connector may be provided in a one-to-one correspondence. Both of the above solutions can reduce the material cost of the first connector and / or the second connector.

[0040] In this embodiment, the human body support surface 111 is provided with at least two linearly extending first recesses 112, which are spaced apart or intersecting on the human body support surface 111. This design increases the number of first recesses 112, thereby increasing the heat dissipation area and improving the heat dissipation effect. Furthermore, depending on aesthetic requirements, the at least two linearly extending first recesses 112 can be designed to be intersecting or spaced apart, enhancing the aesthetic diversity of the seat support cushion 100. For example, in one design, multiple first recesses 112 can be designed to be spaced apart along the length direction of the support core 110; in another design, multiple first recesses 112 can be designed to be spaced apart along the width direction of the support core 110; or, in yet another design, at least two first recesses 112 can be designed to be intersecting to form an X-shape, V-shape, cross shape, etc.

[0041] Furthermore, in this embodiment, the human body support surface 111 of the supporting core 110 is partially concave to form a second recess 113. The second recess 113 is a circular groove, a square groove, a star-shaped groove, etc. The second recess 113 is separated from the first recess 112 and is covered by a covering layer 120. This design provides space for deformation of the portion of the supporting core 110 surrounding the second recess 113, making it easier for the portion of the supporting core 110 to deform. Therefore, the more second recesses 113 there are, the softer the supporting core 110 becomes. Thus, by adjusting the number and distribution of the second recesses 113, the hardness of the supporting core 110 can be adjusted, thereby increasing user comfort. Simultaneously, the design of the second recess 113 also reduces the contact area between the human body support surface 111 and the human body, improving heat dissipation.

[0042] In this embodiment, the seat support cushion 100 is a backrest support cushion. At this time, there are two first recesses 112. The two first recesses 112 are distributed at intervals along the length direction of the seat support cushion 100. Multiple second recesses 113 are provided in a matrix distribution in the area on both sides of the first recesses 112.

[0043] Finally, the seat support cushion 100 in this embodiment also includes a buffer spring 150. The buffer spring 150 is a serpentine spring extending along the length or width of the seat support cushion. The buffer spring 150 is wrapped by the support core 110 or supported on the side of the support core 110 facing away from the human body support surface 111. This design can improve the support of the seat support cushion 100 for the user and can adaptively adjust through the buffer spring 150, thereby achieving a close fit to the curves of the human body and improving user comfort; in addition, it also extends the service life of the support core 110.

[0044] It is understood that in other embodiments of this utility model, the first recess may also be a circular groove, a square groove, or a star-shaped groove, etc.

[0045] It is understood that in other embodiments of this utility model, one of the first connector and the second connector is a female snap fastener and the other is a male snap fastener; or, the first connector and the second connector are magnetic attracting components that rely on magnetic force to attract each other, for example, one of the first connector and the second connector is a magnet and the other is a magnetic metal sheet; or the first connector and the second connector are magnets with opposite magnetic properties; in both of these schemes, the first connector can also be provided on the side wall of the first recess to improve the stability after the decorative seam is formed.

[0046] Example 2

[0047] like Figure 4As shown, this embodiment also discloses a seat, including a seat frame 200 and a backrest frame 300. The backrest frame 300 is equipped with the seat support pad 100 described in Embodiment 1. In this case, the seat support pad 100 serves as a backrest support pad. A buffer spring 150 extends laterally, and both ends of the buffer spring 150 are connected to the left and right side rods of the backrest frame 300, respectively. The buffer spring 150 is wrapped by the support core 110, thereby fixing the seat support pad 100 to the backrest frame 300. By adopting the seat support pad 100 of the above technical solution, the processing efficiency of the seat can be improved, thereby reducing the manufacturing cost of the seat; at the same time, it also facilitates the disassembly and assembly of the cover layer 120, improving the user experience.

[0048] It is understood that in other embodiments of this utility model, the buffer spring may also be supported on the side of the support core facing away from the human body support surface.

[0049] It is understood that in other embodiments of this utility model, the seat frame may also be provided with the seat support pad described in Embodiment 1. In this case, the seat support pad serves as a seat cushion, the buffer spring is wrapped by the support core, the buffer spring extends laterally, and the two ends of the buffer spring are respectively connected to the left and right side rods of the seat frame to fix the seat cushion on the seat frame.

[0050] It is understood that in other embodiments of this utility model, both the seat frame and the backrest frame are provided with the seat support pad described in embodiment one.
