Embodiment 1
[0068] This embodiment is an airbag used as an indoor furniture mattress. figure 1 is a perspective view of an exemplary airbag 100 . figure 2 is a longitudinal cross-sectional view of an exemplary airbag 100 . image 3 is a transverse cross-sectional view of an exemplary airbag 100 .
[0069] Such as Figure 1 to Figure 3 As shown, the airbag 100 includes a first surface 110 , a second surface 120 , four sides, a plurality of tension straps 140 and an air valve 150 .
[0070] The first surface 110 serves as the upper surface of the airbag 100 , and the second surface 120 serves as the lower surface of the airbag 100 , both of the first surface 110 and the second surface 120 are rectangular. The sides include a first side 131 , a second side 132 , a third side 133 and a fourth side 134 . The first side of the first surface 110 is connected to the side above the first side 131 , the second side of the first surface 110 is connected to the side above the second side 132 , t...
Embodiment 2
[0084] In addition to changing the polymer material of Example 1 into the material described below and changing the tension band into Figure 4 Except as shown, other structures are the same as the airbag of the first embodiment.
[0085] The first macromolecule material includes 78 parts by weight of natural rubber, 26 parts by weight of styrene-butadiene rubber (GB8659-88), 3 parts by weight of rosin resin, 4 parts by weight of bis(citramidomethyl)benzene, 2-mercaptobenzo 5 parts by weight of imidazole.
[0086] The second polymer material includes 87 parts by weight of natural rubber, 1 part by weight of rosin resin, 3 parts by weight of bis(citrazolimidomethyl)benzene, and 4 parts by weight of 2-mercaptobenzimidazole.
[0087] Figure 4 is a longitudinal sectional view of another exemplary airbag. Such as Figure 4 As shown, except that the structure of the tensioning band 240 is different from the tensioning band 140 in the first embodiment, other components are the s...

Abstract
The invention discloses an airbag and a mattress. The airbag comprises an outer surface, an accommodation cavity formed by the sealing of the outer surface as well as a puller strap arranged inside the accommodation cavity, wherein the outer surface is made of an airtight material and forms a shape of the airbag during inflation; the accommodation cavity adopts a closed space; in addition, in a state that the airbag does not bear outer pressure, internal pressure of the sealed space is 0.1 to 0.5MPa; the puller strap comprises a first fixed end, a second fixed end and a middle part; the firstfixed end and the second fixed end are respectively and fixedly arranged in different positions of the outer surface in a mode of limiting the inflating shape of the airbag. The edge or corners of theairbag disclosed by the invention still keep specific shapes at certain external pressure. Besides, the puller strap of the airbag disclosed by the invention also has excellent durability.
Description
technical field [0001] The present invention relates to inflatable devices, in particular to cuboid airbags and mattresses with improved durability. Background technique [0002] With the improvement of people's living standards, the demand for mattress categories is more diverse. Because of its lightness and foldability, the airbag mattress greatly reduces the space, which is beneficial to storage and other advantages, making it very practical. Therefore, it is loved by more and more people. [0003] Different from ordinary airbags, airbags that can be used as mattresses need to have a more standardized shape after inflation, generally in the shape of a cuboid. The traditional airbag is connected with the upper and lower sheets of the bed body through a plurality of tension belts, so that after inflation, the mattress can form two flat surfaces and obtain a cuboid shape. For example, CN 105615393 A discloses an airbag and an airbag welding process, and CN 1736293 A discl...
