Description

Independent cylinder seat cushion structure

The present invention provides a technical field of seat cushions, particularly a structural designer of an independent cylindrical seat cushion structure.

According to the customary use of office chairs in offices of all sizes, the seat cushions are made of molded foam glued to the bottom board and then covered with outer cloth. However, this kind of seat cushion is traditionally molded. Foam only relies on its own softness and hardness to support the weight of the human body. On the one hand, it has poor elasticity, making it uncomfortable to sit on and prone to backaches after sitting for long periods of time. On the other hand, traditional molded foam is not breathable, making it difficult to sit for long periods of time. It is easy to be hot and uncomfortable; therefore, the previous technology, such as "Breathable Office Chair" No. I511689, aims to improve the lack of airtightness of traditional chair cushions. The seat cushion system includes a base plate, an independent tube intermediary layer, and an Balance pad and an outer cover, in which the independent cylinder interlayer is composed of a plurality of non-woven independent cylinders covering spring coils and a set of cloth, which covers the independent cylinders as a whole, and the bottom plate, The independent tube interlayer and the balance pad are stacked from bottom to top, and then the bottom plate, the independent tube interlayer and the balance pad are covered with an outer jacket. However, after implementation, the applicant found that the original independent tube interlayer was only covered by the outer jacket and would laterally collapse after being used for a period of time. Moreover, the independent tube interlayer was limited by the barrier and breathable effect of the balance pad. Not good.

In addition, for example, patent No. M281562 "Improvement of the combined structure of pillows and cushions" is composed of an inner body 10, two steel wire layers 20, two foam layers 30 and an outer covering 40, among which: The inner body 10 is a rectangular or other geometrically shaped block. As the characteristics of the material change, the inner body 10 itself has a certain degree of elastic plasticity or softness, mainly in a matrix shape within the inner body 10 A number of independent tubes 11 are formed through the body for accommodating a number of elastic bodies 12 . The two steel wire layers 20 are made of elastic coils and are respectively covered on the two outer surfaces of the inner layer body 10 to cover the elastic bodies 12 . The two foam layers 30 are soft plastic foam bodies, which are respectively placed on the two steel wire layers 20 to suppress the two steel wire layers 20 . However, the above-mentioned inner body 10 has a number of independent tubes 11 formed in a matrix form for accommodating a number of elastic bodies 12. The elastic bodies 12 are limited to point-shaped elastic compression and have no impact on the force on the human body's buttocks. Its softness is bound to be greatly reduced, and its breathability is also poor due to the foam body laminated on the upper end.

Also, for example, patent No. M324450 "Improved structure of seats" mainly includes: seat frame 1, bottom plate 2, elastic support unit 3, first cushion body 4, inner frame 5, second cushion body 6, The outer frame cover 7 and the cover plate 8 and other parts, among which the seat frame 1 is arranged on a plurality of legs 13, and a backrest 14 extends upward from one edge of the seat frame 1, and a receiving space is provided inside the seat frame 1 11. An inwardly protruding annular flange 12 is provided on the bottom edge of the accommodation space 11. The bottom plate 2 is arranged above the annular flange 12 of the seat frame 1 to form a support at the bottom of the accommodation space 11. , the inner frame 5 is a hollow frame with upper and lower parts, which is arranged above the bottom plate 2 and fits the inner peripheral surface of the accommodation space 11 of the seat frame 1 , and the elastic support unit 3 is arranged on the inner frame 5 inside and within the The bottom plate 2 is composed of a plurality of independent tubes arranged side by side and has excellent elasticity. The first pad body 4 is a sheet-like body made of an elastic poly compound, which has excellent toughness and can be placed on the elastic support. Above the unit 3, the outer frame cover 7 is connected to the top periphery of the inner frame 5 and expands laterally outward. It can cover the top periphery of the seat frame 1. The cover plate 8 is composed of a plurality of blocks 81 that are respectively combined with each other. A second cushion body 6 made of elastic fiber is placed on the first cushion body 4, so that the entire body has the same size and shape as the top opening of the accommodation space 11 of the seat frame 1. A complete coverage can be formed inside the outer frame cover 7 . However, the above-mentioned elastic support unit 3 is installed in the inner frame 5, and a layer of first cushion body 4 and cover plate 8 are laid on the upper end. Although it is breathable, the components are complicated, and the inner frame 5 does not have The softness affects the riding comfort, and the structure is only suitable for wooden chairs and is completely unsuitable for office chair seat cushions commonly used by the public.

Since the foam body 10 is internally provided with a hollow cavity 11 with an opening at the bottom to fill the elastic body 20 composed of a plurality of independent spring coils 21, the hollow cavity 11 goes to the top and penetrates to form a plurality of elastic bodies 20. A ventilation hole 12 is formed, and its open end is closed and fixed by the bottom plate 30 provided with the exhaust hole 31, and finally covered with a jacket cloth 40, so that the elastic bodies 20 can be restricted in addition to being connected to each other through fasteners. The hollow groove 11 is surrounded by an outer frame to achieve a fixed effect that will not separate.

2. Furthermore, the elastic body 20 is made up of a plurality of spring coils 21 connected to each other to form an integral whole. Each of the spring coils 21 can produce elastic changes according to different shapes of the human body's buttocks or different seating positions, so that the elastic body 20 Each spring coil 21 inside can produce relative elasticity according to its stress situation, so as to provide excellent supporting elasticity for the buttocks. Comfort.

3. And the foam body 10 can be designed through the ventilation hole 12 on the top of the hollow groove 11 and the exhaust hole 31 on the bottom plate 30, so that when the elastic body 20 is compressed and deformed, it can pass through the ventilation hole 12 on the top of the hollow groove 11.
