Airbag structure

Abstract

The present disclosure relates to an airbag structure, and the airbag structure according to the present disclosure includes a body (100) into which a fluid is injected, wherein a plurality of predetermined points (A) spaced apart from each other is arranged on a side along a lengthwise direction, and a protrusion (200) into which the fluid is injected from the body (100), the protrusion (200) extending from the two adjacent predetermined points (A) in a direction facing away from the body (100), wherein the protrusion (200) has a smaller width of a farthest end from the body (100) than a width of an opposite end connected to the body (100).

What is claimed is: 
     
         1 . An airbag structure, comprising:
 a body into which a fluid is injected, wherein a plurality of predetermined points spaced apart from each other is arranged on a side along a lengthwise direction; and   a protrusion into which the fluid is injected from the body, the protrusion extending from the two adjacent predetermined points in a direction facing away from the body,   wherein the protrusion has a smaller width of a farthest end from the body than a width of an opposite end connected to the body.   
     
     
         2 . The airbag structure according to  claim 1 , wherein when the fluid is injected into the protrusion, the side of the body where the protrusion is formed reduces in length. 
     
     
         3 . The airbag structure according to  claim 1 , wherein when the fluid is injected into the protrusion, the body bends in a direction in which the protrusion is formed. 
     
     
         4 . The airbag structure according to  claim 1 , wherein the protrusion is formed in an arc, quadrangular or triangular shape. 
     
     
         5 . An airbag structure, comprising:
 a first body into which a fluid is injected, wherein a plurality of first predetermined points spaced apart from each other is arranged on one side along a lengthwise direction;   a first protrusion into which the fluid is injected from the first body, the first protrusion extending from the two adjacent first predetermined points in a direction facing away from the side of the first body;   a second body into which the fluid is injected, the second body positioned parallel to the first body, wherein a plurality of second predetermined points spaced apart from each other is arranged on one side along the lengthwise direction;   a second protrusion into which the fluid is injected from the second body, the second protrusion extending from the two adjacent second predetermined points in a direction facing away from the side of the second body; and   a connecting portion formed between the first body and the second body,   wherein the first protrusion has a smaller width of a farthest end from the first body than a width of an opposite end connected to the first body, and   the second protrusion has a smaller width of a farthest end from the second body than a width of an opposite end connected to the second body.   
     
     
         6 . The airbag structure according to  claim 5 , wherein when the fluid is injected into the first protrusion, the side of the first body where the first protrusion is formed reduces in length, and
 when the fluid is injected into the second protrusion, the side of the second body where the second protrusion is formed reduces in length.   
     
     
         7 . The airbag structure according to  claim 5 , wherein when the fluid is injected into the first protrusion and the second protrusion, the first body, the second body and the connecting portion bend in a direction perpendicular to an imaginary line connecting the side of the first body where the first protrusion is formed and the side of the second body where the second protrusion is formed. 
     
     
         8 . The airbag structure according to  claim 5 , further comprising:
 a third body into which the fluid is injected, the third body extending vertically from an end of the connecting portion, wherein a plurality of third predetermined points spaced apart from each other is arranged on one side along the lengthwise direction; and   a third protrusion into which the fluid is injected from the third body, the third protrusion extending from the two adjacent third predetermined points in a direction facing away from the side of the third body,   wherein the third protrusion has a smaller width of a farthest end from the third body than a width of an opposite end connected to the third body.   
     
     
         9 . The airbag structure according to  claim 8 , wherein when the fluid is injected into the third protrusion, the side of the third body where the third protrusion is formed reduces in length. 
     
     
         10 . The airbag structure according to  claim 8 , wherein when the fluid is injected into the third protrusion, the third body bends.
