The specific embodiment

See also Fig. 1, shown in Figure 2, mat liner structure of the present utility model is to be come as upper surface by a high soft gas permeable foam sponge body 1 (being commonly called as inertia memory foam sponge body) of density, the high ventilative foam sponge body 2 of hard of density of arranging in pairs or groups again constitutes the intermediate surface of mat liner, and again by the high soft gas permeable foam sponge body 3 of another one density as base, so stacking mode must maintain soft, the hard, the soft gas permeable foam sponge body that are at least identical or thickness inequality more than three layers or three layers and constitute.That is to say that it is the high soft inertia memory foam sponge body 1 of density that its stacking mode is at least top layer, the centre is the ventilative foam sponge body 2 of the high hard of density, bottom is that the high soft inertia memory foam sponge body 3 so stacking arrangement modes of density constitute, and in the thickness selection of each aspect, can constitute by thickness identical or inequality.For example needed on the implementation mat thickness of inner lining is 9 centimeters, mat liner so of the present utility model is constructed in the stacking arrangement and can is, it is that 3 centimeters high soft inertia memory foam sponge bodies 3 of density are used as base that a slice thickness is set earlier, on the surface of the high soft gas permeable foam sponge body 3 of this density, smear the last layer adhesive agent then, be that the ventilative foam sponge bodies 2 of the high hard of 3 centimeters density are laid on to be binded on the surface of the high soft gas permeable foam sponge body 3 of this density and fix again with a slice thickness, then on the surface of the high ventilative foam sponge body 2 of hard of this density, smear the last layer adhesive agent again, be that 3 centimeters high soft gas permeable foam sponge bodies 1 of density are laid on and are binded fixingly on ventilative foam sponge body 2 surfaces of the high hard of this density again with a slice thickness, can constitute mat liner of the present utility model like this and construct.And when implementing to become the mat liner of thickness aspect inequality, work becomes ventilative 2 of the foam sponge bodies of the high hard of intermediate density and can be 5 centimeters, and the high soft gas permeable foam sponge body 3 of upper and lower two-layer density, respectively be 2 centimeters formations, or the ventilative foam sponge body 2 of the hard that intermediate density is high is designed to 4 centimeters, and the high soft gas permeable foam sponge body 3 of upper and lower two-layer density respectively is the mode of 2.5 centimeters formations.The rest may be inferred, certain compound mode of the present utility model, be not limited to is with smooth bonding fixed form, also can adopt the mode of coating to constitute, example as shown in Figure 3, Figure 4, come by the cutting of soft gas permeable foam sponge body 1,3 one end limits, the foam sponge body 2 of again hard being breathed freely is coated in it and constitutes.

For example above-mentioned Fig. 1, shown in Figure 2, it is 9 centimeters mat liner that the utility model is implemented as to thickness, basically it is three layers, it is respectively soft gas permeable foam sponge body 1, the assembly of ventilative foam sponge body 2 of hard and soft gas permeable foam sponge body 3, so in the use, its upper and lower surface can turn-over be used as the upper strata and be used alternatingly, in addition, when if the utility model will be implemented to become bigger thickness, when for example directly making the sofa or the seat of office chair, when the thickness that for example needs is 15 centimeters seat, then as shown in Figure 5, just can make the three all is same thickness, and for example the soft gas permeable foam sponge body 1 of 5 centimeters thickness is distributed in ground floor topmost, the ventilative foam sponge body 2 of the hard of 5 centimeters thickness is distributed in the centre position, and to give the soft gas permeable foam sponge body 3 of 5 centimeters thickness of a slice in addition then be to be distributed in the 3rd layer of below.It on the implementation, also can make two-layer identical up and down, the intermediate layer is a thickness inequality, for example shown in Figure 6, be distributed in topmost the ventilative foam sponge body 2 of hard of ground floor, 8 centimeters thickness with the soft gas permeable foam sponge body 1 of 3.5 centimeters thickness and be distributed in the centre position to give the soft gas permeable foam sponge body 3 of 3.5 centimeters thickness of a slice in addition then be to be distributed in the 3rd layer of below; Perhaps being three layers on the implementation all is thickness mode inequality, for example shown in Figure 7, be distributed in topmost with the soft gas permeable foam sponge body 1 of 4 centimeters thickness that the ventilative foam sponge body 2 of hard of ground floor, 8 centimeters thickness is distributed in the centre position, the soft gas permeable foam sponge body 3 that gives 3 centimeters thickness of a slice in addition then is to be distributed in the 3rd layer of below.Simultaneously in constructional arrangement, it is the arrangement mode combination of three-layer structure fully that the utility model also is not limited to, also can be arranged in structure arrangement mode more than five layers or five layers in fact in regular turn (as Fig. 8, shown in Figure 9), but spiritual intention feature of the present utility model place, its constructional arrangement mode, it is the foam sponge body that must be positioned at the superiors, be soft ventilative foam sponge body 1 structure, and the below that is positioned at soft gas permeable foam sponge body 1 is to want the hard foam sponge body 2 of breathing freely, and then stacking in regular turn be arranged in kept at least soft, hard, softly constituted by the stacking in regular turn ventilative foam sponge body thickness of arranging out more than three layers or three layers.

In sum, knowing that this case is to have above-described good characteristic, made it on manipulating, promote and to commonly use the usefulness that is not had, and give practicality, really is one to have the good designer of structure of practical value.
