Detailed Description
The detailed description and technical contents of the present invention are described as follows with reference to the drawings:
Referring to fig. 1 to 4, the present invention provides an airbag assembly 10, wherein the airbag assembly 10 is assembled in a cushion 100, and the cushion 100 can be a mattress or a chair cushion. The airbag assembly 10 includes a lower airbag 11 and an upper airbag 12 stacked on the lower airbag 11, wherein the lower airbag 11 has an air inlet 111 and an air passing opening 112, the air inlet 111 is connected to a gas tube 13, so that an inflation gas flowing in the gas tube 13 can enter the lower airbag 11 through the air inlet 111.
On the other hand, the upper layer airbag 12 is composed of a first bag skin 14 and a second bag skin 15, the first bag skin 14 and the second bag skin 15 can be bonded by high frequency or other bonding methods, after the bonding is completed, the upper layer airbag 12 has a bonding edge 121 and a transverse bonding trace 122, the bonding edge 121 bonds the peripheries of the first bag skin 14 and the second bag skin 15, that is, the bonding edge 121 is formed along the edge of the upper layer airbag 12. The transverse tack 122 is connected to two opposite sides (123, 124) of the adhesive edge 121, the two opposite sides (123, 124) are parallel, and the transverse tack 122 is located on a center line 125 of one side 123. Furthermore, the bonding edge 121 and the transverse bonding mark 122 form an i-shaped structure, so that the upper layer airbag 12 is divided into a plurality of inflatable airbag zones 126, and each inflatable airbag zone 126 of the upper layer airbag 12 is provided with an air receiving opening 127 corresponding to the air passing opening 112. The upper layer airbag 12 receives the inflation gas from the gas passing port 112 through the gas receiving port 127, and inflates the bulge. Furthermore, the volumes of the inflatable bladder zones 126 are equal. In one embodiment, each of the air ports 127 is located at the center of one of the inflatable cell regions 126, as shown in FIG. 2. In addition, referring to fig. 1 and 3, when the upper layer airbag 12 is implemented in multiple numbers, the upper layer airbags 12 can be made of the same first bag skin 14 and the same second bag skin 15, two adjacent upper layer airbags 12 are distinguished by the bonding edges (121, 128), and one of the bonding edges (121, 128) of the two upper layer airbags 12 can be overlapped, as indicated by an overlapping edge 129 in fig. 3.
Referring to fig. 1 and 3, the lower layer airbag 11 of the present invention is composed of a third bag skin 16 and a fourth bag skin 17, and the air vent 112 is formed on the third bag skin 16. The third bag cover 16 and the fourth bag cover 17 can also be bonded by high frequency or other bonding methods, after the bonding is completed, the lower layer airbag 11 has a bonding edge 113 for bonding the peripheries of the third bag cover 16 and the fourth bag cover 17, and a middle indentation 116 for connecting two opposite sides of the bonding edge 113.
As mentioned above, the airbag module 10 can be used alone or further used with other elastic members 18, as shown in fig. 4, and the elastic member 18 can be a spring, a sponge, or a latex pad. In addition, the inflated volumes of the upper layer airbag 12 and the lower layer airbag 11 may be different.
Referring to fig. 5-1 and 5-2, fig. 5-1 is a diagram illustrating the conventional airbag 20 and the upper airbag 12 of the present invention in a non-inflated state, and fig. 5-2 is a diagram illustrating the conventional airbag 20 and the upper airbag 12 of the present invention in an inflated state. Bear, current gasbag 20 with the utility model discloses this upper gasbag 12 aerifys the back, can obviously see that current gasbag 20's height 201 is obviously higher than the utility model discloses this upper gasbag 12's height 120, that is to say, the utility model discloses this upper gasbag 12 is less violent in the produced uplift of aerifing the back, and makes this elastic component 18 that this gasbag group 10 of collocation used can not by excessive extrusion, makes this pad body 100 can maintain the roughness, increases this pad body 100's comfort level.
the present invention has been described in detail, but the above description is only a preferred embodiment of the present invention, and the scope of the present invention should not be limited thereby, and all equivalent changes and modifications made according to the claims of the present invention should be covered by the present invention.
