Description

Fixed elastic breathable cushion

The present invention provides a technical field of seat cushions, especially a structural designer of a fixed elastic breathable cushion.

According to the traditional office chairs used in offices of various sizes, the seat cushions are all made of molded foam glued on the bottom plate, and then covered with an outer cloth. However, this type of cushion is traditionally molded. Foam only supports the weight of the human body by its own softness and hardness. On the one hand, it has poor elasticity. It is uncomfortable to sit on and prone to backaches when sitting for a long time. The traditional molded foam is not breathable and is sedentary. It is easy to be stuffy and uncomfortable; therefore, the inventor’s previous application No. 1511689 "ventilated office chair" is to improve the lack of air permeability of the conventional chair cushion, wherein the cushion system includes a bottom plate, an independent tube intermediate layer, A balance pad and an outer cover, wherein the independent cylinder intermediate layer is composed of a plurality of non-woven independent cylinders covering the spring coils and a set of cloth. The cover cloth wraps the independent cylinders into one body. The bottom plate , The intermediate layer of the independent cylinder and the balance pad are stacked from bottom to top, and the bottom plate, the intermediate layer of the independent cylinder and the balance pad are covered with an outer cover. However, the applicant found that the intermediate layer of the original independent cylinder was only covered by the outer cover, and it would collapse after a period of use. Moreover, the intermediate layer of the independent cylinder was restricted by the balance cushion due to the barrier effect of air permeability. Bad.

In addition, for example, the patent case No. M281562 "Pillow and cushion combination structure improvement" 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 block of rectangular or other geometric shapes. As the characteristics of the material change, the inner body 10 itself has a certain degree of elastoplasticity or flexibility, and is mainly formed in a matrix shape in the inner body 10 A plurality of independent cylinders 11 are formed through the state for accommodating a plurality of elastic bodies 12. The two steel wire layers 20 are wound by elastic coils, and are respectively coated on the two outer surfaces of the inner body 10 to cover the elastic bodies 12. The two foam layers 30 are foam bodies with soft plasticity, which are respectively placed on the two steel wire layers 20 for pressing the two steel wire layers 20. However, the inner body 10 described above is formed with a plurality of independent cylinders 11 penetrating in a matrix form for housing a plurality of elastic bodies 12. The elastic bodies 12 are limited to point-like elastic compression, which exerts force on the human buttocks. The softness of the surface is bound to be greatly reduced, and its breathability is also poor due to the laminated foam body at the upper end.

In addition, for example, Patent No. M324450 "Improved Structure of Seats" mainly includes: seat bracket 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, in which the seat bracket 1 is set on the plurality of legs 13, and one side edge thereof extends upward with a backrest 14, and there is an accommodation space inside the seat bracket 1 11. A ring flange 12 protruding inward is provided on the periphery of the bottom side of the accommodating space 11. The bottom plate 2 is arranged above the ring flange 12 of the seat bracket 1 to form a support at the bottom of the accommodating space 11 , The inner frame 5 is an upper and lower hollow frame, which is set on the bottom plate 2 Above and attached to the inner peripheral surface of the accommodating space 11 of the seat frame 1, the elastic support unit 3 is arranged on the inner side of the inner frame 5 and on the bottom plate 2, which is composed of a plurality of independent cylinders arranged side by side, with Excellent elasticity. The first cushion body 4 is a sheet-like body made of an elastic poly compound. It has excellent toughness and can be placed above the elastic support unit 3. The outer frame cover 7 is connected to the top side of the inner frame 5 The peripheral edge and laterally expand outwards, which can cover the top peripheral edge of the seat frame 1. The cover plate 8 is composed of a plurality of pieces of blocks 81 respectively combined with a second cushion body 6 made of elastic fiber to make it The whole has the same size and shape as the top side opening of the accommodating space 11 of the seat bracket 1, so that it is placed on the first cushion body 4 to form a complete cover inside the outer frame cover 7. However, the above-mentioned elastic support unit 3 is arranged in the inner frame 5, and a layer of the first cushion body 4 and the 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 comfort of the ride, and the structure of the composition is only suitable for wooden chairs and office chair cushions that are commonly used by the general public.
