The technical solution of the utility model is: whole pad material is made up of seat cushion and back cushion, and pad material foam has two or more density, and main body and appearance are the basic density foam, and its density is 35-45kg/m
3Or rebound degree 45%-50%, the ad hoc foam of setting and main body and appearance foam different densities or rebound degree in addition at ad hoc position is that density is higher than 55kg/m in the postmedian ischium position of seat cushion
3Or the foam of rebound degree 60%-75%, forwardly the curved position of thigh is that density is lower than 25kg/m
3Or the foam of rebound degree 35%-40%, be that density is higher than 50kg/m in the lumbar vertebrae position and the shoulder blade position of back cushion
3Or the foam of rebound degree 55%-60%.
It is the basic density foam of 1-3cm that ad hoc foam has thickness apart from pad material outer surface.
The thickness of ad hoc foam is not less than 5cm.
Front and back length at the ad hoc foam in ischium position is 8-15cm, left and right sides width is not less than 20cm, length is 8-15cm before and after the curved position of thigh, left and right sides width is not less than 30cm, the lumbar vertebrae position highly is up and down 5-15cm, left and right sides width is not less than 20cm, and the shoulder blade position highly is 5-12cm up and down, and left and right sides width is not less than 30cm.
According to organization of human body, in the ischium position, because the stressed higher foam of density that should be provided with more greatly, stressed less in the curved position of thigh, the less foam of density should be set, to alleviate pressure, in the lumbar vertebrae position to the shank blood vessel, because the human body lumbar vertebrae is stressed big, easily strain should be provided with the higher foam of density to play a supportive role, in the shoulder blade position, it is stressed also bigger, and the higher foam of density should be set.Particular location and the size of each ad hoc foam on the pad material should be determined according to the length of common human body and whole pad material.
Owing to adopted above-described various technical measures, make seat cushion more meet the physiological structure of human body, take more comfortable.
Fig. 1 is the sectional view of a whole set of pad of the utility model material.
Fig. 2 is the section plan of the utility model seat cushion (1).
Fig. 3 is the section plan of the utility model back cushion (2).
Below in conjunction with a description of drawings embodiment of the present utility model.
As Fig. 1, Fig. 2, shown in Figure 3, form a sleeve gasket material by seat cushion (1), back cushion (2), pad material foam has two or more density, and main body and appearance (3) they are the basic density foam, and its density is 35-45kg/m
3Or rebound degree is 45%-50%, and the ad hoc foam of setting and main body and appearance (3) foam different densities or rebound degree in addition at ad hoc position is that density is higher than 55kg/m in the postmedian ischium position (4) of seat cushion (1)
3Or the foam of rebound degree 60%-75%, forwardly the curved position (5) of thigh is that density is lower than 25kg/m
3Or the foam of rebound degree 35%-40%, be that density is higher than 50kg/m in lumbar vertebrae position (6) and shoulder blade position (7) of back cushion (2)
3Or the foam of rebound degree 55%-60%.
Apart from pad material outer surface thickness being arranged at the foam of ad hoc part is the basic density foam of 1-3cm, i.e. the label line indication position of main body and appearance (3) among Fig. 1, and present embodiment is got 2cm, and is thin or thicker as pad material gross thickness, can adjust to 1cm or 3cm thereupon.
