[0038] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate for the embodiments of this application described herein.
[0039] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation. Furthermore, some of the above terms may be used to indicate other meanings besides orientation or positional relationship; for example, the term "upper" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.
[0040] Seats are primarily used in vehicles, such as cars. In vehicles, space is limited, making it difficult for passengers to move around during long drives. To improve comfort, seats are typically covered with elastic support padding, often made of foam. However, foam has poor breathability and can easily harbor bacteria.
[0041] like Figure 1 and Figure 2 As shown, this embodiment provides a seat support pad, which is installed on the seat frame 6 and supports the occupant on the seat. Specifically, the seat support pad includes a base 1 at the bottom and a backrest 3 at the back, and both the base 1 and the backrest 3 are integrally formed three-dimensional structural layers. The three-dimensional structural layers are strip-shaped fiber filaments extruded from thermoplastic polymer elastomer as raw material, which are curled and bonded to form a layer of a certain thickness.
[0042] The strip-shaped fibers are extruded from thermoplastic polymer elastomers using a spinneret. The thermoplastic polymer elastomers can be POE, PE, TPU, EVA, TPEE, PP, PET, recycled materials, etc. After extrusion, the strip-shaped fibers are drawn out in water and come into contact with each other, winding and bonding together. Finally, they are molded in a die to obtain a three-dimensional structural layer.
[0043] In some cases, flame retardants can be added to raw materials containing thermoplastic polymer elastomers to achieve a flame-retardant effect for the support pad.
[0044] First, the layered structure formed by the curling and bonding of strip-shaped fiber filaments in the three-dimensional structural layer of this application has a large number of voids, which gives the seat formed after the three-dimensional structural layer is molded in the seat mold better breathability. Second, the base 1 and the backrest 3 are integrally molded, which improves the production efficiency of the seat.
[0045] As a further improvement, a headrest 5 is also provided on the upper side of the backrest 3. The headrest 5 is also an integrally molded three-dimensional structural layer. The three-dimensional structural layer is made of strip-shaped fiber filaments extruded from thermoplastic polymer elastomer, which are curled and bonded to form a layer of a certain thickness. The material and molding method of the three-dimensional structural layer in the headrest 5 are the same as those in the base 1 and the backrest 3.
[0046] The base 1, backrest 3, and headrest 5 are formed using a hot-press molding process. For example, a seat mold is made according to the required seat shape, and hot-press molding is performed in this mold. After the base 1, backrest 3, and headrest 5 are formed, the base 1 and backrest 3, and the backrest 3 and headrest 5 are connected by a heat-fusion process.
[0047] It should be noted that after the base 1 and backrest 3 are formed, base side wings 2 are formed on the left and right sides of the base 1, and backrest side wings 4 are formed on the left and right sides of the backrest 3. The density of the three-dimensional structural layers in the formed base 1, base side wings 2, backrest 3 and backrest side wings 4 may be the same or different.
[0048] It should also be noted that, in other cases, the base side wings 2 of the base 1 can be formed separately from the other parts of the base 1, and then connected by heat fusion. Similarly, the backrest side wings 4 of the backrest 3 can be formed separately from the other parts of the backrest 3, and then connected by heat fusion. Furthermore, the other parts of the base 1 can also be divided into multiple parts and formed separately according to the actual situation, and then connected by heat fusion. Likewise, the other parts of the backrest 3 can also be divided into multiple parts and formed separately according to the actual situation, and then connected by heat fusion.
[0049] In this embodiment, a groove is formed at the connection between the molded base side wing 2 and other parts of the base 1, which is the base connection groove 11. A groove is formed at the connection between the backrest side wing 4 and other parts of the backrest 3, which is the backrest connection groove 31.
[0050] In addition, several grooves are provided on other parts of the base 1; several grooves are also provided on other parts of the backrest 3. For example, in this embodiment, the base 1 also has a first base groove 12 and a second base groove 13 that are in a different direction from the base connecting groove 11. The backrest 3 also has a first backrest groove 32 and a second backrest groove 33 that are in a different direction from the backrest connecting groove 31.
[0051] To improve the aesthetics and comfort of the seat, a seat cover 7 is typically installed on the surface of the seat support liner. Grooves are provided on the base 1 and backrest 3 to accommodate the seams of the seat cover 7 and prevent it from bulging. Furthermore, to secure the seat cover 7, the fixing points can be located in the grooves. In one case, fixing holes are made in the grooves on the base 1 and backrest 3 to secure the seat cover. In another case, Velcro can be installed in the grooves on the base 1 and backrest 3 for fastening. Specifically, the seat cover can be a fabric cover or a leather cover.
[0052] Regarding the density of the seat, the specific details are as follows: the density of base 1 is 50-120 kg / m³. 3 The density of the backrest 3 is 30-120 kg / m³. 3 The density of the base side wings 2 and the backrest side wings 4 is 30-120 kg / m³. 3 The density of headrest 5 is 30-100 kg / m³. 3 .
[0053] In a preferred embodiment, the side of the base 1 closest to the occupant is a solid layer containing solid strip-shaped fiber filaments with a diameter of 0.4-1.5 mm; the side furthest from the occupant is a hollow layer containing hollow strip-shaped fiber filaments with a diameter of 0.5-2.0 mm, and the thickness of the solid layer accounts for 10-80% of its total thickness. The side closest to the occupant uses strip-shaped fiber filaments with smaller diameters for greater softness and comfort. The side furthest from the occupant uses strip-shaped fiber filaments with larger diameters for greater rigidity and better support.
[0054] In another case, the side of the backrest 3 and headrest 5 closest to the occupant is a solid layer, in which the strip-shaped fiber filaments are solid and the filament diameter is 0.4-1.5mm; the side furthest from the occupant is a hollow layer, in which the strip-shaped fiber filaments are hollow and the filament diameter is 0.5-2.0mm, and the thickness of the solid layer accounts for 10-80% of its total thickness.
[0055] In other cases, either the backrest 3 or the headrest 5 can be configured with a hollow layer or a solid layer.
[0056] Preferably, a leg rest is provided at the end of the base 1 away from the backrest 3; a hand rest is provided near the side wing 2 of the base; and the leg rest and hand rest are both integrally formed three-dimensional structural layers, the structure of which is consistent with the structure of the base 1 or the backrest 3.
[0057] This application also provides a seat, including the aforementioned seat support cushion and frame 6, wherein the seat support cushion is mounted on the seat frame 6 and supports an occupant on the seat. The frame 6 can be formed by welding a steel structure.
[0058] It should be noted that although the seats in this application are mainly used in automobiles, their use in other occasions is not excluded.
[0059] The terms “installation,” “setup,” “equipped with,” and “connection” used herein should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
[0060] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
