Detailed ways

In order to fully understand the purpose, features and effects of the present utility model, the present utility model is described in detail through the following specific embodiments and in conjunction with the accompanying drawings, as follows:

Please refer to FIG. 1 and FIG. 2 . FIG. 1 is a three-dimensional exploded schematic view of the seat back cushion according to the first specific embodiment of the present invention, and FIG. 2 is a three-dimensional combined schematic view of the seat back pad according to the first specific embodiment of the present utility model. As shown in the figure, the seat back cushion 100 includes a first elastic foam pad body 10 and a second elastic foam pad body 13 .

The first elastic foam pad body 10 includes a first cushion unit 11 and a first cushion unit 12 , and the first cushion unit 12 is located at one end of the first cushion unit 11 .

The second elastic foam pad body 13 is arranged on the first elastic foam pad body 10, and the second elastic foam pad body 13 includes a second cushion unit 14 and a second cushion unit 15, the second The cushion unit 15 is located at one end of the second cushion unit 14, and the second cushion unit 15 includes a first support portion 151, a second support portion 152 and a convex portion 153, and the convex portion 153 corresponds to the position of the waist of a human body .

Wherein, the second cushion unit 14 corresponds to the first cushion unit 11 , and the second cushion unit 15 corresponds to one side of the first cushion unit 12 .

In this embodiment, the first elastic foam pad body 10 has a high elastic coefficient, fast shape recovery speed and relatively hard hardness after being pressed, and the first elastic foam pad body 10 is used to support the seat back pad 100 The main body is also the main part that supports the user's weight.

Furthermore, the elastic coefficient of the second elastic foam pad 13 is low and the hardness is relatively soft, so when the second elastic foam pad 13 contacts the user's buttocks and back, the user can feel soft and comfortable, and The second elastic foam pad 13 can be closely attached to the human body according to the uneven contour of the human body surface when under pressure, and the second elastic foam pad 13 will squeeze the first elastic foam when under pressure Pad body 10, so that the first elastic foam pad body 10 provides a reverse support force to support the second elastic foam pad body 13, thereby assisting the second elastic foam pad body 13 to support the user's weight and maintain The user is in balance.

In this embodiment, the convex portion 153 is an ergonomic design, and the convex portion 153 protrudes toward the direction away from the first cushion unit 12, and is used to lean against the second cushion on the back of the user. When the unit is 15, the convex part 153 corresponds to the outer curvature of the user's waist and is supported on the waist to assist the waist to support the weight of the user's upper body, thereby achieving the effect of relieving the pressure on the waist and preventing the user from sitting. The waist is partly suspended in the air, so it is easy to feel soreness and fatigue, and the user's waist and back can be naturally straightened and leaned against the seat cushion 100, so that the user feels more relaxed and smooth. Furthermore, because the waist of the human body is supported, the chest is naturally straightened, the internal organs are naturally smooth and the body is naturally healthy, and the user can feel comfortable and relaxed without being tired after sitting for a long time.

In this embodiment, the second cushion unit 14 and the second cushion unit 15 are integrally formed, and the first cushion unit 11 and the first cushion unit 12 are also integrally formed, so that the first cushion unit 12 is integrally formed during the manufacturing process. Both the elastic foam pad body 10 and the second elastic foam pad body 13 can be directly and integrally cut, so that the second elastic foam pad body 13 can be correspondingly arranged on the second elastic foam pad body 13 conveniently and quickly when the user uses it. On an elastic foam pad body 10.

Specifically, the first elastic foam pad body 10 can be, for example, a foamed cotton layer, and the second elastic foam pad body 13 can be, for example, a memory foam layer or a temperature-sensitive memory cotton layer. Or the density of the temperature-sensitive memory cotton layer is higher than that of general foamed cotton. The memory foam layer or the temperature-sensitive memory cotton layer will change the softness and hardness according to the weight or body temperature felt. For example, the sensory The temperature-sensitive memory cotton layer will become softer as the temperature increases, that is, when the user sits on the seat back cushion 100, the pressure-sensitive part or temperature-sensitive part of the temperature-sensitive memory cotton layer will become soft, and along the human body The uneven stress-bearing surface in contact with the seat back cushion 100 is close to the user's buttocks and back, while the non-temperature-sensitive and non-pressurized parts of the seat back cushion 100 still retain their original elasticity, so they can be tightly and evenly supported The human body achieves the effect of dispersing stress.

As shown in Fig. 3, when using the seat back cushion 100, the seat back cushion 100 can be directly placed on the ground, and the user 1 can sit on the second cushion unit 14 and straighten both feet naturally, and at the same time put the back against the Leaning on the second back cushion unit 15, and the convex portion 153 leans against the waist, at this time, because the second elastic foam pad body 13 is pressed by the weight of the user 1, it is partially softened and sunken, and then It fits closely to the contours of the human body and evenly supports the buttocks and back.

As shown in Fig. 4, when using the seat back cushion 100 at home, the seat back cushion 100 can be placed on an ordinary chair 2, and the first back cushion unit 12 is leaned against the back of the chair. 1. Sit on the second cushion unit 14, place your feet on the ground with your feet bent naturally, and lean your back against the second cushion unit 15, so that the convex part 153 is against your waist; As shown in Figure 5, if the seat cushion 100 is used in an office, the seat cushion 100 can be placed on a computer chair 3, so the position of the seat cushion 100 can be determined by the user 1 according to the use requirements. Change.

Thereby, the seat cushion of the present utility model can provide even and sufficient support for the user's buttocks and back, and can support the user's waist through the convex part 153 to relieve the pressure on the waist. When sitting on the second elastic foam pad body 13, one can feel a sense of comfort, and then can keep sitting for a long time without feeling tired.
