Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to FIGS. 1 to 13.

[Example 1]

First, a window breaker according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 10.

1 to 10, the vehicle emergency window breaker of the present invention, the dashboard (D / S: Dashboard) or the rear windshield (R / W) of the lower side of the front windshield (F / W) of the vehicle The airbag module 1 for glass destruction provided on at least one side of a rear side rear shelf (P / S: Parcel Shelf) of a lower side is comprised so that a glass window can be destroyed by operating in an emergency.

The glass breakage airbag module 1 includes an airbag 110 installed to be deployable and an inflator 120 for rapidly inflating the airbag 110 to a window breakage position.

At this time, the surface of the air bag 110 for breaking the glass is preferably provided with a crushing projection 111 to help the glass to be broken well when colliding with the glass, in particular crushing projection 111 is a metal harder than the glass As a material of the plurality is preferably provided spaced apart from each other.

In addition, the airbag 110 is formed with small holes (not shown) for swelling by the working gas to allow the working gas to escape after a time elapses.

On the other hand, the inflator 120 is caused by an ignition circuit (not shown) that causes electrical ignition of the ignition agent (not shown) so that the gunpowder inside the explosion, and the hot heat generated by the explosion of the gunpowder of the ignition agent It includes a gas generator (not shown) that is burned to generate a working gas.

The glass bag breaking air bag module 1 of the present invention is connected to an ignition circuit (not shown) of the inflator 120 to generate sparks in the circuit, and is operated by a driver or a passenger (eg, a handle shaft or an instrument panel). It is configured to include an operation switch (not shown) drawn out).

On the other hand, the vehicle emergency window breaker of the present invention, the glass fragment defense module (2) to protect the driver and / or passengers from the glass fragments destroyed by the operation of the glass destruction airbag module (1) It is configured to further include.

At this time, the glass debris defense module 2, the housing 210 is provided with a door that can be opened and closed on one side of the lower surface, and the elastic spring, such as one end is fixed to one side wall is fixed to the inner side of the housing 210 A member 220, a protective film 230 connected to the end of the elastic member 220, and the protective film 230 is attached to the end of the protective film 230 to provide a load to the protective film 230 to descend through the opening when opening the door It is configured to include a weight 240 (weight).

In the above-described configuration, the glass shard defense module 2 is such that the shield 230 can be unfolded between the driver and the passenger and the glass window before the front or rear glass window is broken by the operation of the glass destruction airbag module 1. It is installed on at least one side of the front or rear of the vehicle ceiling.

The operation of the present embodiment configured as described above is as follows.

Conventionally, in case of vehicle overturning, the door may not be escaped due to damage of the door due to an accidental impact, but according to the present embodiment, the airbag module for glass destruction by the operation switch (not shown) of the driver or passenger (1) is actuated to break out the windshield F / W and / or the rear windshield R / W so that a quick escape can be achieved.

First, in a vehicle accident except when the vehicle is drowned, the door is not opened due to the damage of the door due to the impact of the accident, so that the front or rear windows must be destroyed and escaped.

More specifically, in a passenger car in which the glass breaker of the present invention is applied to both the front and the rear of the vehicle, the door is not opened by the vehicle overturning while only the driver (not shown) is on and the rear windshield (R / W) rather than the escape through the windshield. It is assumed that it is advantageous to escape through.

If the driver wants to break the rear windshield (R / W) while the door is not open, the driver may move the glass destruction airbag module 1 of the present invention to an operable position (for example, the handle shaft or the front panel of the driver's seat). Locate the airbag module operation switch (not shown) that is withdrawn and press the switch.

When the operation switch is pressed, the glass destruction airbag module 1 installed in the rear seat rear shelf P / S is operated, and the ignition circuit of the inflator 120 constituting the glass destruction airbag module 1 is not shown. In the case of a spark occurs, the spark causes the gunpowder inside the ignition agent (not shown) to explode, and the gas generator (not shown) is combusted by the hot heat generated by the explosion of the gunpowder to generate a working gas. The airbag 110 is rapidly inflated by the working gas.

The airbag 110 collides with the rear windshield R / W during the deployment process by rapid expansion, thereby destroying the rear windshield R / W.

At this time, the surface of the airbag 110 is provided with a plurality of shredding protrusions 111 made of a hard material compared to the glass window to help the glass to be broken well when colliding with the glass window.

In addition, when the rear windshield R / W is destroyed by the inflated airbag 110 as described above, the driver may make an emergency escape through the destroyed rear windshield.

In this case, on the other hand, it is not necessary to operate only the glass breakage airbag module 1 and not operate the glass fragment defense module.

In the above description, it has been described assuming an emergency escape through the destruction of the rear window (R / W), if you want to escape through the windshield (F / W), the glass installed on the dashboard (D / S) of the front of the vehicle By operating the destruction airbag module 1, the windshield (F / W) can be destroyed, and then can of course escape through the windshield.

Next, in a vehicle accident in which the vehicle is drowned, a case in which the door does not open due to water pressure and the front or rear glass windows must be destroyed and escaped will be described.

If a car falls into water during a car accident, the door will not open until water pressure enters the inside of the car and the pressure difference between the inside and outside of the car is resolved. The present invention effectively solves these problems and increases the survival rate.

That is, when the vehicle is drowned, regardless of whether the water pressure is released when the present invention is applied, the driver can immediately try to escape by operating the glass breaking device of the present invention.

More specifically, in the following, the door does not open due to the pressure difference between the inside and outside of the vehicle in a state in which the vehicle is drowned in the state where only the driver (not shown) is in the passenger car to which the glass breaker of the present invention is applied, the rear windshield (R / W) The process of escaping is explained sequentially, assuming the case of escaping through the system.

First, when the vehicle falls into the water, the driver operates the glass fragment defense module 2 before operating the glass destruction airbag module 1 so that the driver is not injured by the glass fragments pushed into the vehicle due to the water pressure during the glass breakdown. When the door is opened, due to the load of the weight 240, the shield 230 descends from the ceiling to cover the driver.

In this state, the driver finds the airbag module operation switch drawn out to the position where the glass breakage airbag module 1 of the present invention can be operated (for example, the steering wheel shaft or the front panel of the driver's seat) and presses the switch.

When the operation switch of the glass breakdown airbag module 1 is pressed, the glass breakdown airbag module 1 installed on the rear seat rear shelf P / S is operated, which constitutes the glass breakdown airbag module 1. Sparks are generated in the ignition circuit (not shown) of the inflator 120, the spark ignited by the spark, and if the gunpowder inside the inflator 120 is triggered by the ignition agent, the hot heat generated by the explosion of the gunpowder is caused. The gas generator (not shown) (eg, nitrogen-containing material) is combusted to generate a working gas (eg, nitrogen), and the airbag 110 is rapidly inflated by the working gas.

The airbag 110 collides with the windshield F / W during deployment by rapid expansion, and thus the windshield F / W is destroyed by the impact action of the airbag 110.

At this time, since the plurality of shredding protrusions 111 made of a harder material than the glass window are provided on the surface of the airbag 110, the glass bag is easily broken when colliding with the glass window, as described above.

When the windshield F / W is destroyed by the airbag 110 as described above, the glass fragments destroyed by the hydraulic pressure are rapidly introduced into the vehicle, and the driver is safely prevented from the glass fragments by the preliminary shield 230. Protected.

In addition, the hydraulic pressure difference between the inside and the outside of the vehicle is also eliminated in the process of performing the protective action by the protective film 230. Accordingly, the driver can make an emergency escape through the rear windshield R / W from which the glass is removed.

In the above description, it was assumed that the emergency escape by breaking the rear window (R / W), but by additionally installing the glass debris defense module (2) so that the shield 230 descends to the front of the driver, if the windshield If it is advantageous to escape through (F / W), the glass fragment defense module (2) is operated to break the glass installed on the dashboard (D / S) of the vehicle with the shield 230 descending toward the driver's face. After operating the airbag module 1 for breaking the windshield (F / W), it is of course possible to escape through it.

On the other hand, if the shield 230 of the glass fragment defense module 2 is unnecessarily lowered due to malfunction and inadequate handling, the shield 230 can be easily returned to its original position.

That is, the protective film 230 is connected to the elastic member 220 is subjected to a tensile force, when holding up the weight 240, the protective film 230 is dragged into the housing 210 by the restoring force of the elastic member 220 When the door is closed again, the glass debris defense module 2 is newly enabled as in the beginning.

[Example 2]

Hereinafter, another embodiment of the glass fragment defense module of the present invention will be described.

11 to 12, another embodiment of the glass fragment defense module according to the present embodiment is an airbag curtain module 3 installed inside the vehicle ceiling, and the airbag curtain module 3 is deployed. Accordingly, the airbag curtain 310 is spread between the driver and the passenger and the broken glass window in a wide and thin plate form, and an inflator 320 for rapidly inflating the airbag curtain 310.

At this time, the inflator 320 is the same configuration as the inflator 120 of the above-described glass destruction airbag module 1, and the ignition circuit (not shown) causing electrical ignition to the ignition agent (not shown) to detonate the internal powder. And a gas generator (not shown) which is burned by hot heat generated by the explosion of the explosive and generates a working gas.

On the other hand, the operation switch (not shown) for operating the airbag curtain module 3 can be configured to serve as an operation switch (not shown) of the airbag module 1 for glass breaking.

In addition, in the present embodiment, the airbag curtain 310 may be unfolded as close to the inclination angle of the glass window as possible, as long as interference with the airbag 110 constituting the airbag module 1 for glass destruction is excluded during deployment. It is preferred to be configured to.

For example, the airbag curtain 310 is configured to be deployed as close to the inclination angle of the glass window as possible when inflated by the design structure of the vehicle body ceiling or the design structure of the airbag curtain itself.

On the other hand, the ignition circuit (not shown) of the inflator 120 of the glass bag airbag module 1 and the ignition circuit (not shown) of the inflator 320 of the airbag curtain module 3 by electrically connecting When the operation switch (not shown) is pressed, the circuit may be configured such that the airbag module 1 for breaking glass and the airbag curtain module 3 for protecting glass fragments operate simultaneously. That is, the glass breakage airbag module 1 and the airbag curtain module 3 may be connected by the same operation circuit.

The operation in the case where the airbag curtain module 3 for protecting glass fragments of the present embodiment configured as described above is applied is as follows.

In the passenger car to which the glass breaker of the present invention is applied, it is assumed that a door must be escaped through a rear windshield (R / W) because the door is not opened due to water pressure while the vehicle is drowned in a state where only a driver (not shown) is on the board. It will be described the operation of the airbag curtain module 3 for the protection of glass fragments of the present embodiment.

When the vehicle is drained, if the driver presses an operation switch (not shown) for operating the glass breakdown airbag module 1, the operation switch also acts as an operation switch of the airbag curtain module 3 so that both modules simultaneously Works.

That is, the airbag curtain 310 constituting the airbag curtain module 3 is rapidly deployed to interpose between the rear seat and the rear windshield R / W, and the airbag constituting the glass destruction airbag module 1 ( 110 is rapidly expanded to collide with the rear window (R / W) to destroy the window (see Figure 12).

The moment the rear windshield (R / W) is destroyed by the airbag 110, the glass fragments destroyed by the water pressure is rapidly introduced into the vehicle, the driver is driven by the airbag curtain 310 draped to shield the rear of the rear seat It is safely protected from glass fragments entering through the rear window (R / W).

Then, the driver's protective action by the airbag curtain 310 is performed, and the hydraulic pressure difference between the inside and the outside of the vehicle is eliminated. .

[Example 3]

FIG. 13 is a block diagram showing another embodiment of an operation circuit of a window breaker airbag module and an airbag curtain module of the present invention. In this embodiment, the airbag curtain module is installed when the airbag curtain module 3 is installed. This is a case where a delay circuit (not shown) is provided so that a time difference occurs at the time of operation so that the airbag module 1 for glass breakdown operates after the operation of (3).

In other words, in the above-described [Example 2], the ignition circuit (not shown) of the glass destruction airbag module 1 and the protective airbag curtain module 3 operate simultaneously when the operation switch (not shown) is operated. As described above, however, a delay circuit (not shown) for generating a time difference at the time of operation of the two modules so that the airbag module for glass destruction 1 operates after the protection of the airbag curtain module 3 as in the present embodiment.
