Description

Technical Field

[0001] The utility model belongs to the technical field of safety airbags, and in particular relates to a scalding-proof airbag structure for a driver's safety airbag. Background Art

[0002] An airbag is a cushioning airbag that inflates quickly when a car decelerates suddenly after a collision. It can protect the occupants from hitting the interior of the car and is a passive safety device1. Its main purpose is to reduce the damage caused by frontal collisions to the occupants of the car.

[0003] The working principle of the airbag is: the sensor system continuously sends speed change information to the control device, which analyzes and judges the information. After the first collision and before the second collision, a gas-filled air cushion is quickly opened, so that the occupant moves due to inertia and falls on the air cushion, thereby alleviating the impact on the occupant and absorbing the collision energy, reducing the degree of injury to the occupant;

[0004] The driver's airbag is mostly a perfect circular symmetrical structure, which can effectively protect the driver's head when inflated. However, since the exhaust holes are mostly arranged at the 12h position, if the driver's hand or forearm is within the 10h to 14h range of the steering wheel when the airbag is deployed, the high-temperature gas generated by the deployment of the airbag will cause burns to the driver's hand or arm;

[0005] In order to solve the above problems, the present application proposes a driver's airbag anti-scalding airbag structure. Utility Model Content

[0006] In order to solve the above problems existing in the prior art, the utility model provides a driver's airbag anti-scalding airbag structure, which has the characteristic of preventing the driver's arm from being burned due to the explosion of the airbag.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a driver's safety airbag anti-scalding airbag structure, comprising an airbag, a vent hole is arranged on the rear side of the airbag, the vent hole is also located at the upper end of the airbag, and a high-temperature resistant isolation cloth is connected to the rear end of the airbag.

[0008] As a preferred technical solution of the utility model, the air bag includes a front bag piece and a rear bag piece, and the exhaust hole is opened on the rear bag piece.

[0009] As a preferred technical solution of the utility model, the high temperature resistant isolation cloth is sewn on the rear part of the rear bag piece and wraps the exhaust hole.

[0010] As a preferred technical solution of the utility model, the high temperature resistant isolation cloth is arranged at the outlet of the exhaust hole and forms an unclosed air cavity.

[0011] Compared with the prior art, the beneficial effect of the utility model is that by adding a layer of high-temperature resistant isolation cloth between the exhaust hole and the body, burns caused by direct contact between high-temperature gas and the body can be avoided, thereby protecting the driver to the greatest extent after the airbag is detonated, and also improving the reliability and safety of the airbag.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example

[0020] See also Figure 1-4 The utility model provides the following technical solutions: a driver airbag anti-scalding airbag structure, including an airbag 1, an exhaust hole 2 is arranged on the rear side of the airbag 1, the exhaust hole 2 is also located at the upper end of the airbag 1, and a high-temperature resistant isolation cloth 3 is connected to the rear end of the airbag 1. In this embodiment, a layer of high-temperature resistant isolation cloth 3 is added between the exhaust hole 2 and the body to avoid direct contact between high-temperature gas and the body to cause scalding, thereby protecting the driver to the greatest extent after the airbag is detonated, and also improving the reliability and safety of the airbag.

[0021] Specifically, the air bag 1 includes a front bag sheet 11 and a rear bag sheet 12 , and the exhaust hole 2 is provided on the rear bag sheet 12 .

[0022] Specifically, the high temperature resistant insulation cloth 3 is sewn on the rear part of the rear bag piece 12 and wraps the exhaust hole 2. In this embodiment, the high temperature resistant insulation cloth 3 is interconnected with the interior of the airbag 1 through the exhaust hole 2, and the high temperature resistant insulation cloth 3 provides a buffer space for the gas inside the airbag 1.

[0023] Specifically, the high temperature resistant isolation cloth 3 is arranged at the outlet of the exhaust hole 2 and forms an unclosed air cavity. In this embodiment, the air cavity provides a buffer space for hot gas, and can also unload the inflated air bag 1 and avoid burns, thereby achieving a double protection effect.

[0024] The working principle and use process of the utility model are as follows: the high-temperature resistant isolation cloth 3 is stably sewn at the position where the exhaust hole 2 is set in the air bag 1, and then folded together during the folding process of the air bag 1. When the air bag 1 is detonated and unfolded, the gas inside the air bag 1 is discharged outward from the exhaust hole 2 to achieve the buffering purpose. At this time, the hot gas inside the air bag 1 passes through the exhaust hole 2 and then passes through the high-temperature resistant isolation cloth 3. Under the action of the high-temperature resistant isolation cloth 3, the hot gas is prevented from being discharged quickly to cause hand injuries, thereby protecting the human body.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
