Description

A kind of Sofa mattress

Technical field

The utility model relates to a kind of seat cushion, in particular to a kind of Sofa mattress.

Background technique

Currently, seat cushion on the market, especially in the seat cushion on sofa or be a kind of thick, same density Seat cushion or two layers of same density seat cushion, in this way, human body sit on cushion when, due to human leg Power is small, and buttocks is puted forth effort greatly, and when human body is reclined, the easy forward slip of buttocks center of gravity influences the comfort of sitting posture.

Summary of the invention

The purpose of the utility model is to provide a kind of buttocks centers of gravity to be not easy forward slip, the strong Sofa mattress of comfort.

The utility model is realized in this way a kind of Sofa mattress, including upper cushion (1) and lower cushion (2), wherein institute It states the contact surface of cushion (1) and lower cushion (2) to cooperate for irregular shape face contact, cushion in the density ratio of lower cushion (2) (1) density is big.

The contact surface of the upper cushion (1) and lower cushion (2) is that the arc gradient tilts face contact.

The contact surface of the upper cushion (1) and lower cushion (2) is Z-shaped face contact.

The contact surface of the upper cushion (1) and lower cushion (2) is tooth form face contact.

The contact surface of the upper cushion (1) and lower cushion (2) is arch face contact.

Clad (3) are arranged in upper cushion (1) top.

The clad (3) is memory cotton layer.

The clad (3) is emulsion layer.

The good effect of the utility model: the utility model is irregular shape due to the contact surface of upper cushion and lower cushion Face contact, therefore, be not easy between upper cushion and lower cushion it is opposite slide, and cushion is big in the density ratio of lower cushion, human body sit when It waits, buttocks center of gravity is not easy to keep Sofa mattress and human buttock and leg more adduction suitable to Forward, more there is comfort.

Detailed description of the invention:

Fig. 1 is the structural schematic diagram of upper cushion Yu lower the first face contact shape of cushion；

Fig. 2 is the structural schematic diagram of upper cushion Yu lower second of face contact shape of cushion；

Fig. 3 is the structural schematic diagram of upper cushion Yu lower the third face contact shape of cushion；

Fig. 4 is the structural schematic diagram of upper cushion Yu lower the 4th kind of face contact shape of cushion.

Specific embodiment

A kind of Sofa mattress described in the utility model is described in further detail with reference to the accompanying drawing.

Embodiment 1

As shown in Figure 1, a kind of Sofa mattress, including upper cushion 1 and lower cushion 2, wherein the upper cushion 1 and lower cushion 2 Contact surface be arc gradient inclined surface be engaged.The density of cushion 1 is big in the density ratio of lower cushion 2.On the upper cushion 1 Clad 3 is arranged in portion, and clad 3 can be used memory sponge, latex also can be used.In the present embodiment, due to human body sitting posture Leg dynamics is smaller, and buttocks dynamics is larger, and lower cushion 2 is bigger than upper 1 density of cushion, and the two contact surface is that arc opens a book and reads inclination Face contact, when human body is sat down as a result, entire center back is moved, and is made sofa and human body back and leg more adduction suitable, is unlikely to picture Conventional sofa equally can forward slip, sit not stable, when to increase clad 3 be memory sponge or latex, elasticity can be increased, allow seat Feel more comfortable.

Embodiment 2

As shown in Fig. 2, a kind of Sofa mattress, including upper cushion 1 and lower cushion 2, wherein the upper cushion 1 and lower cushion 2 Contact surface be the cooperation of Z-shaped face contact, the density of cushion 1 is big in the density ratio of lower cushion 2.1 top of the upper cushion setting packet Coating 3, clad 3 can be used memory sponge, latex also can be used.In the present embodiment, due to the leg dynamics of human body sitting posture Smaller, buttocks dynamics is larger, and lower cushion 2 is bigger than the density of upper cushion 1, and the two contact surface is Z-shaped face contact.And by difference The foam-rubber cushion of density collectively forms the Z-shaped state of spring-like, and possessing in sponge itself makes between sponge except good elasticity Combination also possess good elasticity, allow and be owned by elasticity in material itself and material shape inward-outward direction, be allowed to human body Support is finer and smoother, and dynamics is more complete, and when human body is sat down as a result, entire center back is moved, and allows sofa and human body back and leg Portion's more adduction is suitable, be unlikely to as conventional sofa can forward slip, do not stable, increasing clad 3 is memory sponge or latex When, elasticity can be increased, make seat sense more comfortable.

Embodiment 3

As shown in figure 3, a kind of Sofa mattress, including upper cushion 1 and lower cushion 2, wherein the upper cushion 1 and lower cushion 2 Contact surface be engaged for toothed surface, the density of cushion 1 is big in the density ratio of lower cushion 2.1 top of the upper cushion setting Clad 3, clad 3 can be used memory sponge, latex also can be used.In the present embodiment, due to the leg power of human body sitting posture Degree is smaller, and buttocks dynamics is larger, and the density of cushion 1 is big in the density ratio of lower cushion 2, and the two contact surface is tooth form face contact Cooperation, makes the combination more consolidation of upper and lower two layers of Sponge cushion, there is more sensitive induction point relative to top-down pressure, More than smooth combination consolidation simultaneously, difficult to slide, as a result, when human body is sat down, entire center of gravity is moved back, and allows sofa and people Body back and leg more adduction are suitable, be unlikely to as conventional sofa can forward slip, sit not stable, increasing clad 3 is note When recalling cotton or latex, elasticity can be increased, make seat sense more comfortable.

Embodiment 4

As shown in figure 4, a kind of Sofa mattress, including upper cushion 1 and lower cushion 2, wherein the upper cushion 1 and lower cushion 2 Contact surface be engaged for arcuate surface, the density of cushion 1 is big in the density ratio of lower cushion 2.1 top of the upper cushion setting Clad 3, clad 3 can be used memory sponge, latex also can be used.In the present embodiment, due to the leg power of human body sitting posture Degree is smaller, and buttocks dynamics is larger, and the density of cushion 1 is big in the density ratio of lower cushion 2, and the two contact surface is arch face contact Cooperation, can be docile with sofa very well when human body is sat down, since there is the soft sponge (density is small) of fraction in front when standing up, To make to stand up more laborsaving, as a result, when human body is sat down, entire center of gravity is moved back, and allows sofa and human body back and leg More adduction is suitable, be unlikely to as conventional sofa can forward slip, sit it is not stable, when to increase clad 3 be memory sponge or latex, Elasticity can be increased, make seat sense more comfortable.

Although what the utility model was discussed is Sofa mattress, the technical solution of the utility model is also covered by otherwise Seat cushion, such as seat cushions, as long as using the seat cushion of technical solutions of the utility model, also by the protection of the utility model.
