Embodiment Construction
[0016] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0017] see figure 1 , a load-dispersing self-adjusting airbag backpack, comprising a backpack body 1, a strap 2, a back-protecting airbag 3, a waist-protecting airbag 4 and an inflatable assembly 5, the back-protecting airbag 3 is arranged on the inner side of the backpack body 1, the The waist support airbag 4 is arranged on the inner side of the strap 2, and the back support airbag 3 has the same structure as the waist support airbag 4. The back support airbag 3 includes several ventilation channels 31, and the several ventilation channels 31 ( Such as image 3 shown) is symmetrically distributed and conforms to the structural characteristics of the back of the human body. The air flow channel 31 includes the upper layer of cloth, the middle layer of cloth with glue on the surface, and PVC glue from the outside to the inside. Among them, t...

The invention discloses a load-distributing self-adjusting bag packsack, comprising a backpack body, back straps, a back-protective bag, a waist-protective bag and an inflating component; the back-protective bag comprises a plurality of vent passages distributed in symmetry and meeting the structural characteristics of a human back, the vent passages comprise upper fabric, surface-glued middle fabric and PVC (polyvinyl chloride) glue from outside to inside, the upper fabric is attached to the corresponding surface-glued middle fabric, the PVC glue is attached to the inner side of the backpack body via high-frequency bonding, and the middle fabric is attached to the PVC glue via high-frequency bonding while a gap for gas passing is reserved between the middle fabric and the corresponding PVC glue; the back-protective bag and the waist-protective bag are inflated through the inflating component, load is distributed through gas in the vent passages, burden of a weight upon a human body is reduced, and body diseases due to stress concentration are avoided; gas is self-adjustable; the load-distributing self-adjusting bag packsack is easier and simpler to use, highly comfortable and very suitable for travel and for people such as students, and causes no additional influence to students.
Description
technical field [0001] The invention belongs to the field of bags, in particular to a self-adjusting air bag backpack with distributed force and comfortable load distribution. Background technique [0002] When traveling and students go to school, they all need a backpack to pack items and books. There are many kinds of backpacks on the market, and they all make some differentiated changes in style and style, but there are big problems. The stress distribution points are on the neck and the waist on both sides. The stress points are very concentrated and heavy, and the comfort is very poor. For a long time, the backpack is prone to frozen shoulders and uneven shoulders, which brings a lot of pain to our body. Hidden dangers of disease bring many backpack diseases, and the impact on students is also great. The pressure of learning itself is great, and the impact of heavy objects and external forces is even greater, which will have unnecessary additional impact on students' le...
