Side airbag structure

Abstract

The present invention relates to the field of automotive safety technology, specifically a side airbag structure comprising a main panel folded in half along a vertical centerline. After the fold, the edge of the main panel is sewn and fixed from the bottom fold line upward near the exhaust hole. The edge is open from the exhaust hole to the top fold line. A secondary panel is sewn to the open structure, and the secondary panel gradually narrows from the middle toward the exhaust hole and the top fold line. By adding the secondary panel above the main panel, the area above the airbag is increased when the airbag is inflated and deployed, while also increasing the contact area with the arm to form a support surface, ensuring the arm is lifted. The overall thickness of the airbag is also increased, effectively reducing the impact of side impacts on the human ribs and improving protective performance.

Description

Technical Field

[0001] The present invention relates to the technical field of automobile safety, and in particular to a side safety airbag structure. Background Art

[0002] The side airbag is an auxiliary protection device in the vehicle airbag system. When the side of the vehicle collides with an obstacle during driving, the side airbag system is activated and the inflator in the system inflates the side airbag, causing it to pop out and deploy instantly. A flexible buffer body is formed to pave the ribs and arms of the driver and passengers before they collide with the equipment in the vehicle, reducing the impact on the ribs and arms of the driver and passengers, reducing the damage to the ribs and arms caused by side impacts, and ensuring the mobility of the upper limbs and the ability to escape.

[0003] At present, the existing side airbag structure is made of a main cloth piece folded in half and sewn at the edges. After inflation and expansion, an airbag structure with a bulge in the middle and a thin edge is formed. The contact area with the arm is small, and sometimes the arm cannot be guaranteed to be lifted, causing the hard arm to squeeze the body's ribs, increasing the chance of fracture. Summary of the Invention

[0004] In view of the above problems, an embodiment of the present invention provides a side airbag structure.

[0005] One aspect of the present invention provides a side airbag structure, including a main piece folded along a vertical center line. After the fold, the edge of the main piece is sewn and fixed from the bottom fold line position upward to the exhaust hole position, and the edge is open from the exhaust hole position to the top fold line position. A secondary piece is sewn at the open structure position, and the secondary piece is a structure that gradually narrows from the middle to the exhaust hole position and the top fold line position.

[0006] Compared with the prior art, the beneficial effects of the present invention are: a secondary plate is added on the upper part of the main plate, which increases the deployment area above the airbag when the airbag is inflated and deployed, and at the same time increases the contact area with the arm part to form a support surface, ensuring that the arm part is lifted, and can increase the overall thickness of the airbag, effectively reducing the impact of side collisions on the human body's ribs, and improving protection performance.

[0007] Optionally, the main piece has a structure in which the upper and lower sides are inwardly concave arcs and the left and right sides are in outwardly convex arcs.

[0008] Optionally, the concave curvature of the lower side of the main piece is greater than the concave curvature of the upper side.

[0009] Optionally, the portion of the secondary piece opposite to the upper connecting position in the main piece is the widest, and gradually narrows from the widest portion to the exhaust hole position and the top fold line position. The upper connecting position refers to the connecting position between the upper edge of the main piece and the left and right sides. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0018] See also Figures 1 to 5 A side airbag structure provided by an embodiment of the present invention includes a main panel folded along a vertical center line. After the fold, the edge of the main panel is sewn and fixed from the bottom fold line position upward to the exhaust hole position, and the edge is open from the exhaust hole position to the top fold line position. A secondary panel is sewn at the open structure position, and the secondary panel is gradually narrowed from the middle to the exhaust hole position and the top fold line position.

[0019] In practice, the main piece has a structure with concave upper and lower edges and convex left and right edges. The concave curvature of the main piece's lower edge is greater than that of the upper edge, while the convex curvature of the left and right edges is the same. The secondary piece is widest at the point opposite the upper connection point of the main piece, and gradually narrows from the widest point toward the vent and the top fold line. The upper connection point refers to the point where the upper edge of the main piece meets the left and right edges.

[0020] This application adds a secondary piece on the upper part of the main piece. When the airbag is inflated and expanded, the expansion area above the airbag is increased. At the same time, the contact area with the arm is increased to form a support surface, ensuring that the arm is lifted, and the overall thickness of the airbag is increased, effectively reducing the impact of side collisions on the human body's ribs and improving protection performance.

[0021] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
