Abstract

A knapsack includes a main body, a strap, and a pull ring. The main body has a receiving space which has a mounting portion which is connected with an air inflation bottle which has an output terminal which has a pin. The strap has is connected with the main body and has a safety air bag which is connected to the output terminal of the air inflation bottle. The pull ring is extended into the strap and is connected with the pin.

AI Technical Summary

Benefits of technology

[0013]According to the primary advantage of the present invention, when the safety air bag is triggered and opened, the neck protection portion of the safety air bag is expanded in a straight direction to protect the user's neck and chest, and the waist protection portion of the safety air bag is expanded in a transverse direction to protect the user's back, spine and waist, so that the knapsack can buffer the shock and protect the user's body to prevent the user from being injured due to a strong or violent hit.

[0014]According to another advantage of the present invention, the water container supplies drinking water to the user through the drinking straw so as to prevent the user from suffering sunstroke due to a large loss of water.

[0015]According to a further advantage of the present invention, the safety air bag of the strap is inflated instantaneously to float on the water so that the knapsack functions as a lifesaving suit or life buoy so as to protect the user and to prevent the user from being drowned.

[0016]According to a further advantage of the present invention, when the user falls out of the bicycle during riding, the pull ring is pulled by the drawing line to open the safety air bag, so that the safety air bag is inflated and expanded instantaneously so as to protect the user's body efficiently.

[0017]Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

[0018]FIG. 1 is a perspective view of a knapsack in accordance with the preferred embodiment of the present invention.

Problems solved by technology

However, the conventional knapsack does not a guard or safety function and cannot protect the user's body at an emergency condition, thereby limiting the versatility of the conventional knapsack.

Thus, when the user falls out of a bicycle during riding or when the user is submerged in the water, the conventional knapsack cannot provide any buffering or lifesaving function during emergency.
