Description

Technical Field

[0001] The utility model relates to the technical field of automotive airbags, and particularly to a co-pilot airbag for preventing lateral sliding of an automobile. Background Art

[0002] See Figures 1 to 4 , in the figure, a conventional co-pilot airbag of an automobile is shown, which is installed in the instrument panel 1 and is composed of an airbag 10 and a gas generator 20. See Figure 5 , the airbag 10 is sewn by an intermediate piece 11 and left and right side pieces 12a, 12b.

[0003] When a frontal collision occurs to the automobile, the co-pilot airbag of the automobile expands and unfolds to form a cushion located between the occupant and the instrument panel, which is used to absorb the energy generated by the collision to protect the occupant. Its upper side contacts the front windshield 2, its lower side contacts the instrument panel 1, and its front end face contacts the occupant 3, as Figure 1 , Figure 2 and Figure 3 shown. When a frontal offset collision or an angular collision occurs to the automobile, the occupant 3 will deviate from the center of the airbag, as Figure 4 shown, and it is easy for the occupant 3 to slip off from the edge of the airbag, that is, to slip out from the side of the airbag, failing to play a protective role and causing injuries to the occupant.

[0035] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below with reference to specific illustrations.

[0036] See Figure 6 and Figure 9 As shown in the figure, a co-pilot airbag for preventing side slip of a vehicle is provided, which includes an airbag 100 and a gas generator 200.

[0037] The airbag 100 is installed in the vehicle instrument panel 1 in a folded manner and is located in front of the co-pilot. The gas generator 200 is installed in the vehicle instrument panel 1 and is used to inflate the airbag 100. When a collision occurs, the gas generator 200 is detonated to inflate the airbag 100. After inflation, the airbag 100 rapidly expands and unfolds. Its upper side contacts the front windshield 2, its lower side contacts the instrument panel 1, and its front end face contacts the occupant 3.

[0038] After the airbag 100 expands and unfolds, a recessed wrapping portion 110 for wrapping the occupant and preventing the occupant from slipping laterally is formed at the position where it contacts the occupant 3. The recessed wrapping portion 110 includes a supporting surface 111 and left and right convex arc surfaces 112a, 112b. The supporting surface 111 contacts the occupant. The left and right convex arc surfaces 112a, 112b extend along the length direction of the recessed wrapping portion 110, are symmetrically arranged on the left and right sides of the supporting surface 111 and bulge outwards, and are used to prevent the occupant from slipping laterally. When a frontal collision occurs, the front of the occupant mainly directly contacts the supporting surface 111 of the recessed wrapping portion 110 of the airbag 100, as Figure 10 shown; when a frontal offset collision or an angular collision occurs, in addition to contacting the supporting surface 111 of the recessed wrapping portion 110 of the airbag 100, the front of the occupant also contacts the left convex arc surface 112a or the right convex arc surface 112b of the recessed wrapping portion 110, and the left convex arc surface 112a or the right convex arc surface 112b restricts the occupant from slipping, as Figure 10 shown.

[0039] Pulling belts 140a, 140b (140’) are sewn in the airbag 100. After the airbag 100 expands and unfolds, the positions where the airbag 100 contacts the occupant are pulled inwards through the pulling belts 140a, 140b (140’), so that a recessed wrapping portion 110 is formed at the positions where the airbag 100 contacts the occupant.

[0040] See Figure 7 As shown in the figure, a schematic exploded view of an airbag 100 of the present invention is provided. It includes an intermediate cut piece 120, a left cut piece 130a, a right cut piece 130b, and pulling belts 140a, 140b.

[0041] The intermediate piece 120 has a long strip structure, which is wider at the position where it contacts the occupant and narrower at the other positions. At the position where the intermediate piece 120 contacts the occupant, spindle-shaped openings 121a and 121b are spaced apart. At the position where the intermediate piece 120 contacts the vehicle instrument panel 1, an air inlet hole 122 connected to the gas generator 200 is provided. Exhaust holes 131a and 131b are provided on the left side piece 130a and the right side piece 130b.

[0042] During sewing, first, the two end edges 123 and 124 of the intermediate piece 120 are sewn together so that the intermediate piece 120 forms a ring. Then, the edge 1211a of the spindle-shaped opening 121a of the intermediate piece 120 is sewn together and sewn integrally with one end 141a of the pull strap 140a, and the other end 142a of the pull strap 140a is sewn on the inner surface of the intermediate piece 120 near the air inlet hole 122. Similarly, the edge 1211b of the spindle-shaped opening 121b of the intermediate piece 120 is sewn together and sewn integrally with one end 141b of the pull strap 140b, and the other end 142b of the pull strap 140b is sewn on the inner surface of the intermediate piece 120 near the air inlet hole 122. Finally, the peripheral edge 132a of the left side piece 130a is sewn to the left peripheral edge 125 of the sewn ring-shaped intermediate piece 120, and the peripheral edge 132b of the right side piece 130a is sewn to the right peripheral edge 126 of the sewn ring-shaped intermediate piece 120.

[0043] When a collision occurs, the position where the intermediate piece 120 contacts the occupant is pulled inward through the pull straps 140a and 140b, so that a concave wrapping part 110 is formed at the position where the intermediate piece 120 contacts the occupant.

[0044] See Figure 8 , in the figure, another exploded structural schematic diagram of the airbag 100' of the present invention is given, which includes an intermediate piece 120', a left side piece 130a', a right side piece 130b' and a pull strap 140'.

[0045] The intermediate piece 120' has a long strip structure, which is wider at the position where it contacts the occupant and narrower at the other positions. At the position where the intermediate piece 120' contacts the occupant, spindle-shaped openings 121' are spaced apart. At the position where the intermediate piece 120' contacts the vehicle instrument panel 1, an air inlet hole 122' connected to the gas generator 200 is provided. Exhaust holes 131a' and 131b' are provided on the left side piece 130a' and the right side piece 130b'.

[0046] During sewing, first sew the two end edges 123’ and 124’ of the middle piece 120’ together so that the middle piece 120’ forms a ring. Then sew the edges 1211’ of the spindle-shaped opening 121’ of the middle piece 120’ together and sew them integrally with one end 141’ of the drawstring 140’. The other end 142’ of the drawstring 140’ is sewn on the inner surface of the middle piece 120’ near the air inlet 122’. Finally, sew the peripheral edge 132a’ of the left piece 130a’ to the left peripheral edge 125’ of the sewn ring-shaped middle piece 120’, and sew the peripheral edge 132b’ of the right piece 130b’ to the right peripheral edge 126’ of the sewn ring-shaped middle piece 120’.

[0047] When a collision occurs, the position where the middle piece 120’ contacts the occupant is pulled inwards through the drawstring 140’, so that a concave wrapping portion 110 is formed at the position where the middle piece 120’ contacts the occupant, which is in an inverted V shape when viewed from above.
