[0001] This utility model relates to the field of seat cushion technology, specifically to a multifunctional seat cushion. Background Technology

[0002] As an important component of car seats, car seat cushions are widely used in various types of passenger cars, commercial vehicles, and trucks. Their core purpose is to cover and protect the seat area, while also slightly improving the basic tactile experience of passengers through the physical properties of their materials (such as softness and abrasion resistance).

[0003] Currently, most mainstream car seat cushions on the market use single or simple composite material structures. Common materials include ordinary fabrics, artificial leather, leather, and combinations with basic sponge interlayers. Their working principle relies solely on the softness and surface characteristics of the material itself to directly contact the human body, achieving the basic functions of "coverage + basic cushioning". Although some products may make simple optimizations such as adding ventilation holes to the material surface, the comfort is still limited and the function is singular.

[0004] Therefore, there is an urgent need to develop a multifunctional seat cushion to expand its functions and improve riding comfort. Utility Model Content

Detailed Implementation

[0019] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0020] like Figure 1-3 As shown, the multifunctional seat cushion provided in this embodiment has a functional structure installed inside, which includes an airbag assembly 1 and a flexible heating wire 2.

[0021] like Figure 2 As shown, the airbag assembly 1 includes an air pump and multiple massage airbags 11, each massage airbag 11 being connected in parallel to one or more air pumps (not shown) via pipes 12.

[0022] Preferably, each massage airbag 11 is laid flat on the supporting base plate 13 in a planar structure. Each massage airbag 11 is installed on the supporting base plate 13 by welding or riveting, so that when the massage airbag 11 is inflated, it can inflate upwards, applying a more significant massage force to the user's body and improving the user experience. One or more massage airbags 11 are grouped together and connected to a common pipe 12. Each pipe 12 is equipped with a solenoid valve (not shown) to control the gas flow direction, thereby realizing the zoned massage operation of each group of massage airbags 11.

[0023] Furthermore, the massage airbag 11 adopts a corrugated tubular structure with both ends sealed, and the bottom end is fixed to the support base plate 13. When the massage airbag 11 is inflated, it can extend towards the user's body rather than fully expand, which is conducive to further enhancing the massage effect.

[0024] Specifically, the massage airbag 11 is controlled by an external chip to inflate and deflate the air pump. The force and sequence of inflation and deflation are adjusted by controlling the inflation and deflation time and pressure.

[0025] The flexible heating wire 2 is laid on the airbag assembly 1 and connected to an external power source. The flexible heating wire 2 is connected to an external power source and an external chip. The external chip controls the start and stop of the flexible heating wire 2 and the temperature adjustment.

[0026] like Figure 2 and Figure 3 As shown, further, an air bag assembly 3 is installed between the airbag assembly 1 and the flexible heating wire 2. The air bag assembly 3 includes an air bag 31 and a blower 32. The air bag 31 is laid flat on the planar structure formed by the arrangement of various massage air bags 11, and multiple air outlets 311 are opened on the top of the air bag 31. The blower 32 provides air source to the air bag 31, and the gas generated by the blower 32 will be discharged from each air outlet 311 and discharged outside the multi-functional seat cushion.

[0027] Specifically, the blower 32 is a miniature blower, and the air bag 31 is connected to one or more blowers 32, with the blower 32 located at the edge of the air bag 31. When inserting the functional structure into the multi-functional seat cushion, the blower 32 should be placed away from the direct pressure position of the seat cushion and at the edge of the seat cushion to reduce pressure on the blower 32.

[0028] The air bag 31 uses a soft support material from the sealing materials to achieve both soft support and ventilation. Air is delivered to the air bag 31 by a blower 32, which is connected to an external chip via wiring. The external chip controls the start and stop of the blower 32, as well as the airflow intensity and duration. When ventilating the air bag 31, it moves in sync with the different areas of the massage airbags 11, providing cushioning and diffusion of pressure for the inflated massage airbags 11, making the massage more comfortable. It also provides a smoother transition between the inflation and deflation of the massage airbags 11 in different areas, significantly improving the massage experience.

[0029] Preferably, the air bag 31 is filled with a mesh support layer 312. The mesh support layer 312 can open up the upper and lower sides of the air bag 31, which helps to support the air supply space inside the air bag 31 and ensure that the gas is smoothly discharged from each air outlet 311.

[0030] Preferably, the top surface of the air bag 31 is covered with a sponge layer 313, which can cover the air bag 31 and the massage airbag 11 below, so that there is no foreign body sensation during use and the comfort of use is improved. A heat insulation pad 314 is laid on the sponge layer 313. The heat insulation pad 314 can be a non-woven fabric pad. The surfaces of the sponge layer 313 and the heat insulation pad 314 are provided with holes that are adapted to each air outlet 311. The flexible heating wire 2 is laid on the heat insulation pad 314 along a curved path and avoids each air outlet 311. The flexible heating wire 2 can be fixed to the heat insulation pad 314 by means of adhesive or snap-fit.

[0031] Specifically, the multifunctional seat cushion includes a backrest portion 4, a headrest portion 5, and a seat cushion portion 6. The seat cushion portion 6 and the headrest portion 5 are respectively connected to both ends of the backrest portion 4, and a functional structure is independently installed inside at least one of the backrest portion 4, the headrest portion 5, and the seat cushion portion 6. As the most preferred embodiment, the functional structure is independently installed inside the backrest portion 4, the headrest portion 5, and the seat cushion portion 6 to provide a more comprehensive massage, ventilation, and heating effect.

[0032] Preferably, a support pad 41 is connected to the front side of the back cushion 4 near the seat cushion 6. The support pad 41 has an independently installed functional structure. The support pad 41 can provide effective support for the user's sacrum, adapt to the curve of the human body, and prevent the user's waist from being unsupported.

[0033] It should be noted that zippers are provided on the back cushion 4, head cushion 5, seat cushion 6 and support cushion 41 to facilitate the insertion or removal of functional structures, making disassembly and subsequent maintenance convenient.

[0034] It should be noted that the back cushion 4, head cushion 5, seat cushion 6 and support cushion 41 are all made of breathable or perforated materials to allow cold air or heat to escape, thereby improving ventilation and heating efficiency.

[0035] Preferably, the back cushion 4, head cushion 5, and seat cushion 6 are all connected to side support pads 7 to provide all-around cushioning for the user and improve comfort. The seat cushion 6 is provided with two independent leg support pads 61 at the end away from the back cushion 4. The far end of the leg support pads 61 is bent downward. The leg support pads 61 are used to cushion the user's calves and popliteal fossa, providing more comprehensive cushioning and improving comfort. The two leg support pads 61 are set separately, which is conducive to cushioning the user's legs and has better applicability.

[0036] Specifically, both the side support pad 7 and the leg support pad 61 are filled with sponge or air bladders to ensure comfort. In one embodiment, the filling material in the side support pad 7 and the leg support pad 61 is an air bladder connected to an external air pump, which controls the support force by inflating and deflating the air bladder.

[0037] This invention can meet the needs of various environments and different groups of people, achieving a comfortable state when sitting for a long time and reducing human fatigue.

[0038] The massage airbags 11 are inflated by an air pump, lifting the soft air bags 31 and various cushion layers. This lifting force is transmitted to the corresponding seat cushion surface, allowing the user to feel the lifting pressure. Conversely, deflating the massage airbags 11 releases pressure, allowing the user to feel a gentle impact. Multiple massage airbags 11 can massage different body parts such as the back, waist, sacrum, buttocks, and legs, enhancing the user's seating experience. The air bags 31 not only provide ventilation but also work in conjunction with the massage airbags 11 to provide smooth support, making the alternating movements of the massage airbags 11 smoother.
