Abstract

A cushion structure is a multilayer structure stacked on top of each other and bonded by adhesive. The stacking sequence from bottom to top is a support bottom layer, a buffer layer, a rear groove, a suspension support layer, a viscoelastic body layer and A comfortable top layer, and when the user sits down, the pressure will be supported from top to bottom. The viscoelastic layer has the characteristics of shock absorption and pressure dissipation, which can disperse and absorb the downward pressure, and then support it through the suspension The combination of the layer and the buffer layer enables the downward pressure to be suspended and supported by the suspension support layer to prevent the weight of the hips and thighs from pressing down on the support bottom layer. Due to the design of the suspension support, In addition to being able to support the sitting body, it can also avoid various discomforts caused by the seat bones being pressed down and contacting the supporting layer to produce a reaction force, especially for users who have injured hips or coccyx. structure.

Cushion structure

This creation is about a cushion structure, especially a cushion structure that can suspend and support the weight of the hips and thighs.

Nowadays, people are busy at work. Some office workers sit in chairs for long periods of time to deal with things, and keep their bodies in the same posture for 5~7 hours. Certain parts of the body (such as hips or sit bones) bear the pressure of body weight for a long time. It makes people feel quite uncomfortable, so in order to improve their discomfort, most of them will be used with a cushion.

However, most cushions on the market are made of foam blocks, but due to the design of this type of cushion, the weight of the hips is often directly pressed on the cushion. Office workers in modern offices often need to sit on a chair for a long time. For a few hours, using this type of cushion will cause the end of the ischium to be compressed, which will cause soreness, numbness, and pain when sitting for a long time in the hip or coccyx. Therefore, how to design a cushion that can balance the pressure on the buttocks will be very important.

The thickness is 15~25mm, and the density is 25~50 kg/m ³ .

As shown in Figures 5A-5B, when the user sits down, the weight of the buttocks 71 and thighs 72 will be lowered by the comfortable top layer 5 and received by the viscoelastic body layer 4, due to the shock absorption of the viscoelastic body layer 4 Pressure characteristics, so it can absorb and disperse the downward weight;

After that, the weight is further carried down by the suspension support layer 3. Due to the combination of the suspension support layer 3 and the buffer layer 2, the following support spaces are formed: (1) To support the buttocks 71, the suspension support layer 3 is opposite to the buttocks 71 and is tied to the suspension support layer 3, the upper rear notch 223, the lower rear notch 211, and the rear notch 11 to form a buttocks support space; (2) To support the left thigh 72, the suspension support layer 3 is opposite to the left thigh 72, and is tied to the suspension support layer 3, the left front notch 221, and the first buffer layer 21 to form a left thigh support space; (3) To support the right thigh 73, the suspension support layer 3 is tied to the suspension support layer 3, the right front notch 222, and the first buffer layer 21 relative to the right thigh 73 to form a right thigh support space; (4) Combining the above three points, two front grooves can be formed relative to the thighs, and a back groove is also formed relative to the hips. The front groove and the back groove can respectively conform to the human body. Engineering, in order to achieve the effect of suspending and supporting the thighs and buttocks, especially the part of the back groove, in addition to stably supporting and protecting the buttocks, it also allows the buttocks to fall naturally in the space formed by the back groove , In order to achieve the effect of stable support and protection of the buttocks; (5) As mentioned above, when the suspension support layer 3 receives weight, it can suspend and support the sinking weight in the support space at different positions, because the suspension support layer 3 has good cushioning characteristics and Support, so the suspension support layer 3 will not collapse and the weight will be completely pressed down to the bottom of the support space, so the weight of the user’s hips and thighs will not be pressed down on the cushion, which can also be avoided Various discomforts caused by excessive compression of the seat bones due to the flattening of the cushion or the reaction force generated by the downward pressure contact.

In addition, as shown in Figures 6A and 6B, the viscoelastic body layer 4 and the foam support layer 41 can also not be added, and the comfort top layer 5 is directly stacked and bonded on the surface of the suspension support layer 3, where the combination is The cushion structure can also achieve a good suspension support effect and a shaping effect for hip and leg shapes.

When comparing the cushion structure provided by this creation with other conventional technologies, its advantages are as follows: (1) This creation has designed a multi-layer structure. The stacking order from bottom to top is a support bottom layer, a buffer layer, a rear groove, a suspension support layer, a viscoelastic body layer and a comfortable top layer. When the user sits down, through the combination of the suspension support layer and the buffer layer, the downward pressure can be supported by the suspension, so as to prevent the weight of the hips and thighs from pressing down on the support bottom layer. (2) Due to the design of the suspension support, this creation not only allows the sitting body to be supported, but also avoids various reaction forces and discomforts caused by the sitting bones due to downward pressure and touch, and it can also affect the hips. Shape and leg shape achieve good shaping effect. (3) The cushion created by this creation is more suitable for wheelchair cushions. Because wheelchair users often need to sit down suddenly due to inconvenience, if it is a normal cushion, the weight of the body will cause impulse injuries to the body. ; However, if the cushion structure of this creation is used, not only can it produce a reclining effect so that the wheelchair can sit up and straighten the spine, it can also make the body of the user sitting in the wheelchair able to be better due to the suspension support. For stability. (4) This creation has been disclosed through the above-mentioned embodiments, but it is not intended to limit this creation. Anyone familiar with this technical field with general knowledge should understand the aforementioned technical features and embodiments of this creation, and will not depart from it. Within the spirit and scope of this creation, some changes and modifications can be made. Therefore, the scope of patent protection of this creation shall be subject to what is defined in the claims attached to this specification.
