[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 first connector 1 on it;

[0031] Functional pad 3, with a second connector 2 on the functional pad 3 corresponding to the first connector 1. The second connector 2 and the first connector 1 are integrally connected and fixed or detachably connected and fixed by a fastener, thereby fixing the functional pad 3 to the car seat.

[0032] In a preferred embodiment, the first connector 1 and the second connector 2 are welded or nailed together.

[0033] like Figure 1As shown, the seat body includes seat foam 5 and seat cover 4. Seat foam 5 is disposed on the seat frame, and seat cover 4 covers seat foam 5. Functional pad 3 is disposed between seat foam 5 and seat cover 4. Functional pad 3 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. First connector 1 is disposed on seat cover 4 of seat body, located on the side of seat cover 4 close to functional pad 3. Second connector 2 is disposed on the circumferential edge of functional pad 3. Both first connector 1 and second connector 2 can be made of non-woven fabric. By applying ultrasonic waves to the contact surface of first connector 1 and second connector 2, high-frequency vibration is generated, thereby causing the contact surface of the two to fuse and fix each other. Of course, other welding methods such as high-frequency welding can also be used. First connector 1 and second connector 2 can also be connected by fasteners, such as C-shaped nails. The C-shaped nails pass through first connector 1 and second connector 2 in sequence to fix the two to each other. Of course, fasteners can also be connecting ropes or male and female buckles, or other structures that can fix the two.

[0034] By setting corresponding first connector 1 and second connector 2 on the seat body and the functional cushion 3 respectively, the first connector 1 and the second connector 2 can be fixed by ultrasonic welding or by fixing parts such as C-shaped nails. Compared with the traditional double-sided tape pasting method, no adhesive is needed, thus avoiding the generation of odor.

[0035] In a preferred embodiment, the seat body includes a seat foam 5 and a seat cover 4. The seat cover 4 is provided with a plurality of first connectors 1 on the side near the seat foam 5. A functional pad 3 is provided between the seat foam 5 and the seat cover 4. The functional pad 3 includes a base material 31. The base material 31 is provided with a plurality of second connectors 2 in the circumferential direction. The base material 31 is provided with a conductor wire 32 on the side near the seat cover 4.

[0036] like Figure 1 , Figure 2 and Figure 4As shown, the car seat includes a seat frame, seat foam 5 is set on the seat frame, and seat cover 4 is wrapped around the seat foam 5. Three tension straps are provided on the side of the seat cover 4 near the base material 31. The tension straps are made of non-woven fabric and have a profile strip connected to their free ends. The profile strip is approximately cylindrical and made of PP material. The tension straps and profile strip form the first connector 1 mentioned above. A functional pad 3 is provided between the seat foam 5 and the seat cover 4. The functional pad 3 corresponds to the back area of ​​the car seat and includes a base material 31 and conductor wires 32. The base material 31 can be made of non-woven fabric or fiber woven material, etc., and has multiple second connectors 2 on its circumferential edge. The multiple second connectors 2 can each correspond to a first connector 1. The conductor wires 32 are distributed in a coiled shape on the side of the base material 31 near the seat cover 4. The conductor wires 32 are electrically connected to the vehicle power supply. When working, they can generate heat or detect whether there are people on the car seat, or both functions can be implemented alternately.

[0037] In a preferred embodiment, the first connector 1 has a plurality of first welding portions 11, and the second connector 2 has a second welding portion 21, with the first welding portion 11 and the second welding portion 21 corresponding one-to-one.

[0038] like Figure 2 and Figure 3 As shown, corresponding welding points, namely the first welding part 11 and the second welding part 21, are marked on the tension straps of the first connector 1 and the second connector 2, respectively. The first welding part 11 and the second welding part 21 are aligned and their surfaces are brought into contact. Ultrasonic waves are generated by an ultrasonic generator and act on the contact position of the first welding part 11 and the second welding part 21. The generated high-frequency vibration can make the first welding part 11 and the second welding part 21 fuse together, thereby fixing the functional pad 3 to the seat cover 4.

[0039] In a preferred embodiment, the first connector 1 has a plurality of first connecting holes 12, and the second connector 2 has a second connecting hole 22, with the first connecting hole 12 and the second connecting hole 22 corresponding one-to-one; it also includes a plurality of fasteners, which can pass through the first connecting hole 12 and the second connecting hole 22 in sequence to fix the first connector 1 and the second connector 2 together.

[0040] like Figure 4 and Figure 5As shown, each second connector 2 has a second connecting hole 22, and the tension strap of the first connector 1 has multiple first connecting holes 12 corresponding to the second connecting holes 22. C-shaped nails are passed through the first connecting holes 12 and the second connecting holes 22 in sequence, and then external force is applied to reduce the distance between the two ends of the C-shaped nails, thereby fixing the functional pad 3 to the seat cover 4. Furthermore, when the C-shaped nails pass through the first connecting holes 12 and the second connecting holes 22, one end of the C-shaped nail is passed through the outside of the profile strip of the first connector 1, so that the profile strip passes through multiple C-shaped nails in sequence. Since the diameter of the profile strip is greater than the thickness of the tension straps of the first connector 1 and the second connector 2, the separation of the functional pad 3 from the seat cover 4 due to the C-shaped nails falling off during use can be avoided by ensuring that the profile strip cannot pass through the distance between the two ends of the C-shaped nails.

[0041] In a preferred embodiment, the free ends of the plurality of second connectors 2 may be aligned with the free ends of the corresponding first connectors 1.

[0042] like Figure 2-5 As shown, by aligning the free ends of the multiple second connectors 2 with the side of the three strips near the tension strap, the functional pad 3 can be positioned, and the installation position of the functional pad 3 on the car seat can be determined.

[0043] In a preferred embodiment, the free end of the first connector 1 is provided with a plurality of first notches, and the free end of the second connector 2 is provided with a second notch 23, the projections of the first notches and the second notch 23 completely coincide; or the free end of the first connector 1 has a plurality of protrusions, the outer contour of the protrusions matching the inner contour of the second notch 23.

[0044] like Figure 2 and Figure 3 As shown, in this embodiment, the first notch, the second notch 23, 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 can be opened on the tension strap of the first connector 1, and the second notch 23 is opened on the free end of the second connector 2 and corresponds to the first notch one by one. By aligning multiple first notches and multiple second notches 23 at the same time, so that the first notch and the second notch 23 coincide, the installation position of the functional pad 3 on the car seat can be determined. Similarly, the second notch 23 can also be a protrusion. By making multiple protrusions located in the corresponding first notches, the installation position of the functional pad 3 on the car seat can also be determined.

[0045] In a preferred embodiment, the seat foam 5 includes a foam body 51, and a plurality of soft pads 52 are provided between the foam body 51 and the functional pad 3. There is a gap between two adjacent soft pads 52. A strip hole 33 is provided on the functional pad 3 corresponding to the gap. The seat cover 4 can be fixed to the foam body 51 through the strip hole 33 and the gap.

[0046] like Figure 1 As shown, the foam body 51 is disposed on the seat frame. A groove is provided on the foam body 51 corresponding to the lumbar and back area of ​​the occupant. Multiple soft pads 52 are disposed in the groove along the height direction of the seat. There is a gap between two adjacent soft pads 52. The base material 31 includes a first pad and a second pad that are integrally connected. The first pad corresponds to the lumbar and back area of ​​the occupant, and the second pad corresponds to the shoulder and neck area of ​​the occupant. A strip hole 33 extending along the width direction of the seat is provided on the first pad corresponding to the gap. Conductor wires 32 can be distributed around the strip hole 33. The seat cover 4 can be fixed to the foam body 51 through the strip hole 33 and the gap.

[0047] In a preferred embodiment, a first groove is provided on the foaming body 51 corresponding to a plurality of first connectors 1, and the plurality of first connectors 1 can be disposed in the first groove.

[0048] like Figure 1 As shown, the first groove is arranged around the recess. After the first connector 1 and the second connector 2 are fixedly connected, they can be embedded in the first groove, thereby avoiding the welding point or C-shaped nail from causing the surface of the seat cover 4 to bulge, preventing the passenger from feeling a foreign object when sitting, and affecting the comfort of sitting.
