[0028] Example 1
[0029] As mentioned in the background section, in order to solve the problems existing in the prior art, this embodiment provides an assembly structure for an automotive seat function cushion, including:
[0030] The seat body has at least one Velcro hook surface 2.
[0031] Functional pad 1 has a velvety joint portion corresponding to the hook surface 2 of nylon hook. The velvety joint portion can overlap with the hook surface 2 of nylon hook to form a fixed connection, so as to fix the functional pad 1 to the seat body.
[0032] In a preferred embodiment, the velvety joint is a napped surface 13 of the substrate, and the napped surface 13 of the substrate is integrally formed on the functional pad 1; or the velvety joint is a hook and loop fastener 3, and the hook and loop fastener 3 of the nylon fastener is provided on the functional pad 1 corresponding to the hook and loop fastener 2.
[0033] like Figure 1-3As shown, the seat body includes seat foam 4 and seat cover 5. Seat foam 4 is disposed on the seat frame, and seat cover 5 covers the seat foam 4. Functional pad 1 is disposed between seat foam 4 and seat cover 5. Functional pad 1 can be a heating pad with heating function, a human body detection pad with human body detection function, or a functional pad with both functions. Nylon hook surface 2 is disposed on the seat body. The pile-like joint on the functional pad 1 can be obtained in two ways. One is by pile-forming the substrate 11 surface to form a piled surface 13. This can be done by pile-forming the entire surface of the substrate 11, so that the entire surface is piled, or only the area of the substrate 11 surface corresponding to the nylon hook surface 2 is pile-formed. The above treatment method can be selected according to the actual situation. The other is to set the nylon hook surface 3 on the functional pad 1 by sewing or welding. In use, the nylon hook surface 2 can be mechanically fitted with the substrate piled surface 13 or the nylon hook surface 3 to form a stable connection, thereby fixing the functional pad 1 to the seat body.
[0034] By setting a base pile surface 13 or a nylon hook and loop fastener surface 3 on the functional pad 1, and simultaneously setting a nylon hook and loop fastener surface 2 corresponding to the base pile surface 13 or the nylon hook and loop fastener surface 3 on the car seat, compared with the traditional double-sided tape method, the base pile surface 13 or the nylon hook and loop fastener surface 3 can be directly overlapped and fixed with the nylon hook and loop fastener surface 2, eliminating the step of peeling off the release paper, which facilitates the installation and fixing of the functional pad 1. Moreover, the overlapping method does not require the use of adhesive, further avoiding the generation of odor. The base pile surface 13 or the nylon hook and loop fastener surface 3 and the nylon hook and loop fastener surface 2 can be repeatedly interlocked or separated under external force without affecting the connection performance between the two. This allows the functional pad 1 to be adjusted during installation, and it is also convenient to disassemble and replace if there is a malfunction or damage during subsequent use. In the following embodiment, the base pile surface 13 is mainly used as an example for introduction, which can be replaced with the nylon hook and loop fastener surface 3 as needed.
[0035] In a preferred embodiment, the seat body includes a seat foam 4 and a seat cover 5, with a functional pad 1 provided between the seat foam 4 and the seat cover 5. The functional pad 1 includes a base material 11, and a conductor wire 12 is provided on the side of the base material 11 near the seat cover 5.
[0036] like Figure 1 As shown, the functional pad 1 is set on the seat foam 4, corresponding to the back area of the car seat, and includes a substrate 11 and a conductor wire 12. The substrate 11 can be made of non-woven fabric or fiber woven material, etc. The conductor wire 12 is coiled and distributed on the side of the substrate 11 near the seat cover 5. The conductor wire 12 is located in the central area of the substrate 11, and there is a gap between it and the circumferential edge of the substrate 11. The conductor wire 12 is electrically connected to the vehicle power supply and can generate heat or detect whether there are people on the car seat when working, or the two functions can be implemented alternately.
[0037] In a preferred embodiment, the substrate 11 has at least one substrate napped surface 13 on the side away from the conductor wire 12, and at least one nylon hook surface 2 is provided on the side of the seat foam 4 near the functional pad 1.
[0038] like Figure 3 As shown, the side of the substrate 11 away from the seat foam 4 is calendered to form a smooth and flat surface for setting conductor wires 12. Multiple areas on the side close to the seat foam 4 are napped to form a napped surface 13 of the substrate. Multiple hook surfaces 2 are pre-embedded in the seat foam 4. The hook surfaces 2 can be mechanically engaged with the napped surface 13 of the substrate to fix the functional pad 1 on the seat foam 4. Furthermore, the area where the napped surface 13 of the substrate is set can also be replaced with a napped surface 3 of the hook surface 3.
[0039] In a preferred embodiment, the substrate 11 has at least one napped surface 13 on the side near the conductor wire 12, and the seat cover 5 has a plurality of extensions 51 on the side near the functional pad 1, with nylon hook surfaces 2 provided on the extensions 51.
[0040] like Figure 4 and Figure 5 As shown, the central area of the substrate 11 near the seat cover 5 is calendered to form a smooth and flat surface for the conductor wire 12. The gap between the conductor wire 12 and the circumferential edge of the substrate 11 is napped to form three napped surfaces 13. The three napped surfaces 13 are distributed on both sides and the top of the substrate 11 along the width of the car seat. The seat cover 5 near the substrate 11 has three tension straps corresponding to the napped surfaces 13. The tension straps are made of non-woven fabric, and their free ends are connected to profile strips. The profile strips are approximately cylindrical in structure and are made of PP material. The suspension strap and the molding strip form the aforementioned extension 51. The hook surface 2 of the nylon hook can be sewn onto the suspension strap. By providing the extension 51 on the seat cover 5, the extension 51 is used to set the hook surface 2 of the nylon hook. The hook surface 2 of the nylon hook is connected to the napped surface 13 of the base material 11. After the connection is completed, the extension 51 can be placed in the groove of the seat foam 4 to avoid the connection part of the two causing the surface of the seat cover 5 to bulge, preventing the passenger from having a foreign body sensation when sitting and affecting the comfort of sitting. Similarly, the above three napped surfaces 13 of the base material can also be replaced with hook surface 3 of nylon hook.
[0041] In a preferred embodiment, the seat foam 4 includes a cushion 41, which is aligned with the circumferential edge of the substrate 11.
[0042] like Figure 3As shown, the seat foam 4 includes a foam body 42. A groove is provided on the foam body 42 corresponding to the lumbar and back area of the passenger. A soft pad 41 is provided in the groove. The soft pad 41 is softer than the foam body 41, which can further improve the comfort of the passenger. The base material 11 includes a first pad and a second pad that are integrally connected. The first pad corresponds to the lumbar and back area of the passenger, and the second pad corresponds to the shoulder and neck area of the passenger. The soft pad 41 and the first pad can be aligned with the two sides of the first pad along the width direction of the car seat, thereby determining the installation position of the functional pad 1 in the width direction of the car seat. At the same time, the soft pad 41 and the first pad can be aligned with the two sides of the first pad along the height direction of the car seat, thereby determining the installation position of the functional pad 1 in the height direction of the car seat. In a conventional seat foam 4 without a soft pad 41, a groove is provided between the back support area and the side support area of the seat foam 4. The two sides of the first pad along the width direction of the car seat can be aligned with the grooves on both sides of the back support area.
[0043] In a preferred embodiment, a plurality of first notches 14 are provided on the circumferential edge of the substrate 11, and a plurality of second notches are provided on the seat foam 4 corresponding to the plurality of first notches 14, the projections of the first notches 14 and the second notches completely overlap; or the seat foam 4 has a plurality of protrusions corresponding to the plurality of first notches 14, the outer contour of the protrusions matching the inner contour of the first notches 14.
[0044] like Figure 4 As shown, in this embodiment, the first notch 14, the second notch, and the protrusion are all triangular in shape. In other embodiments of this application, the shapes of the three can be adjusted synchronously according to the actual situation, and no special limitation is made here. Multiple first notches 14 can be opened on both sides of the first cushion body along the width direction of the seat, and multiple second notches are opened on both sides of the cushion 41 along the width direction of the seat, and correspond one-to-one with the first notches 14. By aligning multiple first notches 14 and multiple second notches at the same time, the installation position of the functional cushion 1 on the car seat can be determined. Similarly, the second notch can also be replaced by a protrusion. By making multiple protrusions located in the corresponding first notches 14, the installation position of the functional cushion 1 on the car seat can also be determined.
[0045] In a preferred embodiment, the edges of the plurality of extensions 51 are respectively aligned with the circumferential edges of the substrate 11.
[0046] like Figure 4 and Figure 5 As shown, the installation position of the functional pad 1 on the car seat can be determined by aligning the edge of the substrate 11 with the side of the three strips near the suspension strap.
[0047] In a preferred embodiment, a plurality of first notches 14 are provided on the circumferential edge of the substrate 11, and a plurality of second notches are provided on the plurality of extensions 51 corresponding to the plurality of first notches 14, wherein the projections of the first notches 14 and the second notches completely overlap; or the plurality of extensions 51 have a plurality of protrusions corresponding to the plurality of first notches 14, wherein the outer contour of the protrusions matches the inner contour of the first notches 14.
[0048] like Figure 4 and Figure 5 As shown, multiple first notches 14 can be formed on both sides of the substrate 11 along the width direction of the seat, and multiple second notches are formed on the tension strap of the extension 51 and correspond one-to-one with the first notches 14. By aligning multiple first notches 14 and multiple second notches at the same time, the installation position of the functional pad 1 on the car seat can be determined. Similarly, the second notches can also be protrusions. By making multiple protrusions located in the corresponding first notches 14, the installation position of the functional pad 1 on the car seat can also be determined.
