Abstract

PROBLEM TO BE SOLVED: To eliminate discomfort caused by a sudden rise of the pressure in a cabin when an air bag inflates. SOLUTION: Simultaneously with inflation of air bags Ba and Bb activated by a collision sensing sensor 2 installed in a vehicle, at least one of window breaking devices for the vehicle, that is glass breaking actuators Aa to Ae provided for windows Ca to Ce is operated. This causes breakage of at least a part of windows of the vehicle to let the interior of the cabin widely open the atmosphere for avoiding a sudden rise of the pressure in the cabin and generation of a high level sound pressure preventing the driver and passengers from being discomforted. Since the glass breaking actuators Aa to Ae may also be operated by a switch 3 manually manipulated by the driver or passengers or a water sensing sensor 4 independent of the air bag, they can be operated manually or automatically in the case of any collision or submergence accident to break the windows for aiding escape of the driver and passengers.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window glass breaking apparatus for a vehicle, and more particularly to an apparatus which cooperates with an air bag apparatus for automatically expanding and protecting an occupant in the event of a collision, and Protects occupants, assists in escaping through vehicle windows, or facilitates rescue from outside by destroying vehicle windows in vehicle emergencies, including those that operate in the event of a vehicle submersion The present invention relates to an occupant protection, escape, or rescue device.

[0002]

2. Description of the Related Art An airbag device provided as an occupant restraint protection device in a vehicle such as an automobile is used to instantaneously release air when a change in acceleration of a vehicle exceeding a predetermined value is detected, such as when a vehicle collides. A safety device for inflating a bag to restrain and protect an occupant, usually a sensor for detecting a collision, an inflator as a gas generator, an ignition device for the inflator, an airbag inflated by gas generated from the inflator, and an inflator , Together with an airbag case that stores the airbag together with the airbag, and a determination module that controls the operation of the airbag device as necessary.

The above-mentioned sensor senses the impact at the time of collision in the form of deformation or acceleration change of the vehicle body, and sends a signal when these reach a predetermined level or more to promote gas generation by ignition of the inflator. As described above, those that sense the deformation of the vehicle body, such as those that operate electrical contacts by deformation of the vehicle body at the time of collision, those that detect the deformation speed from the action of the dashpot or changes in inductance, etc., have been proposed. ing. Sensors that detect changes in acceleration include mechanical sensors typified by Preed's viscous damping sensor, roller mitite sensors from TRW Techner, and inertia of metals and liquids typified by spring mass damping sensors. Numerous systems have been proposed, such as an electromechanical sensor using a moment or the like, a so-called electronic sensor such as a strain gauge, a piezoelectric system, and an operating capacitance detection system. However, for the sake of certainty and other reasons, the latter method that uses the acceleration is mainly adopted.

Further, as an inflator, a gas generating agent such as sodium azide burns via an igniting agent by an igniter which receives a signal from the sensor as described above.
Generally, a solid type that generates a large amount of gas instantaneously is used.
A stored gas type, which is sealed in a high-pressure cylinder of 0 to 250 kg / cm ² and the sealing plug is crushed with an explosive to discharge gas, or a hybrid type combining a solid type and a stored gas type, etc. is there. In either case, it is common to operate by directly receiving a signal from the sensor or, if a judgment module or the like is provided, to receive and operate via the module.

[0005] The airbag device is provided at a predetermined position for the purpose of protecting the occupant in the driver's seat, the passenger seat, and the rear seat at the time of a frontal collision.
It is considered that the airbag device is provided also on the side surface of the vehicle interior such as the inside of a door for the purpose of protecting the occupant against the impact from the side surface. In some cases, these airbag devices are provided in combination. The most common of these is that in vehicles equipped with driver and passenger airbag devices, the gas blown out of the inflator at the time of the collision may cause a short period of several tens of milliseconds. Then, an airbag having a volume of about 30 to 180 liters inflates and appears in the vehicle interior.

By the way, in recent vehicles, traveling with a window glass closed has become common with the spread of air conditioners. As a result, the interior of the vehicle interior is an almost closed space having a limited capacity, except for a portion provided with a constant ventilation port having a small flow rate. Therefore, at the time of a vehicle collision, as described above, the airbag, which occupies a considerably large proportion of the volume of the semi-enclosed space having a substantially limited capacity, instantaneously inflates. Suddenly rises or a high level of sound pressure is generated, which causes discomfort to the occupants.

On the other hand, the occupant may feel some discomfort due to the gas from the inflator that escapes from the airbag device. Therefore, it is very preferable that the ejected gas stays in the closed vehicle compartment as described above. Not really. Therefore, in order to avoid these problems, the interior of the vehicle and the space outside the vehicle are communicated with each other when the airbag is inflated to release the interior of the vehicle under atmospheric pressure, and the pressure increase is quickly and sufficiently released. It is necessary to keep the pressure in the passenger compartment from substantially increasing.

Therefore, in the prior art described in, for example, JP-A-48-18913, a high-pressure gas is injected into a hollow seal fixing a window glass of a vehicle by a signal of a collision sensor, and the hollow seal is injected. A vehicle interior pressure adjusting device has been proposed in which a window glass of a vehicle is removed by inflating the interior of the vehicle to communicate between the vehicle interior and the exterior of the vehicle.

However, in this apparatus, the high-pressure gas is filled in the thin hollow seal, and the vehicle window glass is removed by utilizing the expansion of the hollow seal at that time, so that the high-pressure gas is injected and filled into the thin hollow seal. It takes a considerably long time to reach the state where the windowpane is removed from the windowpane, and the windowpane is removed by operating the device within a time sufficient for almost instantaneous pressure rise due to inflation of the airbag, and It is actually difficult to avoid the pressure rise in the room,
Further, since the mechanism such as the installation of a high-pressure gas cylinder and the installation of a hollow seal becomes complicated, this conventional technique has problems in operation reliability, cost, and the like.

Another conventional technique is disclosed in Japanese Patent Laid-Open No. 7-2
In Japanese Patent No. 036, in order to improve the time delay of operation and the problem of installation of a cylinder seen in the above-mentioned prior art, a dedicated ventilation hole for pressure adjustment is provided in a part of a wall surface separating a vehicle interior and an exterior. And a lid opening device for opening the ventilation hole thereof, and the lid opening device is operated by the signal of the collision sensor, and the interior of the vehicle is communicated with the outside of the vehicle by the ventilation hole, thereby reducing the pressure in the vehicle interior. 2. Description of the Related Art A vehicle interior pressure adjusting device that is opened to the outside of a vehicle is proposed.

However, in the second prior art airbag cabin pressure regulator, the gas flow capacity is limited depending on the size of the air hole. Because the size of the ventilation hole is limited by the design of the vehicle, the ventilation hole exerts a sufficient effect as a pressure adjustment mechanism that needs to release a large amount of gas into the outside air in an instant It is difficult. In addition, large modifications to the current vehicle, such as installation of ventilation holes and opening devices, lead to increased costs,
Another problem is that the degree of freedom in vehicle design is limited.

In any case, the two prior arts described above only consider protecting the human body from the impact of a vehicle collision by deploying an airbag.
Considering a severe collision accident that actually deploys an airbag, despite the fact that it is necessary to not only protect the human body by deploying the airbag but also escape and rescue the occupants after the collision, However, there is also a problem that no consideration is given to occupant escape and rescue other than occupant protection in the event of a collision.

[0013]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has been developed in consideration of the above situation.
Furthermore, even in the case of a rear-seat or side collision, the interior of the passenger compartment is opened to the atmosphere with sufficient gas flow capacity within a predetermined short time, in synchronization with the inflation of the airbag by the operation of these devices. It is a primary object to provide a means for converting. A second object is to provide means for facilitating subsequent escape and rescue of the occupant. The invention also relates to other vehicle accidents, such as in the case of a submergence accident,
The third objective is to provide a means that enables the occupants to escape and rescue in situations where rescue is difficult, and furthermore, after satisfying them, minimizes modification and cost increase to existing vehicles. Another object of the present invention is to provide means that can be realized easily.

[0014]

According to the present invention, there is provided, as a means for solving the above-mentioned problems, an apparatus for breaking a window glass of a vehicle according to the claims.

According to the first aspect of the present invention, the collision detection sensor provided for activating the airbag system mounted on the vehicle senses a certain degree of impact that needs to activate the airbag system. Occasionally, at the same time as activating the airbag system, the window glass breaking device of the vehicle is also activated. Accordingly, when the airbag is inflated within a short time and the pressure in the vehicle interior rapidly rises, at least a part of the window glass of the vehicle is destroyed at the same time, and the vehicle interior is largely opened to the atmosphere. Thereby,
It is possible to prevent a sudden increase in the pressure in the vehicle compartment and a high level of sound pressure from occurring, thereby preventing the occupant from feeling uncomfortable.

According to a second aspect of the present invention, the vehicle is provided with an airbag system, and a window glass breaking device is provided for a window glass of the vehicle. A glass breaking actuator is provided. Therefore, the glass breaking actuator is also activated at the same time as the activation of the airbag system, and the facing window glass is destroyed, so that the interior of the vehicle is greatly opened to the atmosphere, so that the pressure in the interior of the vehicle rapidly rises and a high level of sound pressure is generated. Can be prevented from occurring.

According to the third aspect of the present invention, a signal output from the collision detection sensor is input to a control device serving as a determination module and processed. When the control device detects a vehicle collision based on a signal output from the collision detection sensor when the vehicle collides, the control device activates the airbag system to inflate the airbag. At the same time, the control device also activates the glass breaking actuator to break the window glass of the vehicle and open the interior of the vehicle to the atmosphere. At this time, whether or not the signal is necessary to activate the airbag system and the glass breaking actuator, or whether to trigger the glass breaking actuator with a time difference with respect to the inflation of the airbag. Since the airbag system and the glass breaking actuator are not activated by a small impact because it is determined by the control device, and the time difference between the two is optimized when activated, the pressure inside the cabin is increased by the inflation of the airbag. The window glass is destroyed at the time when the vehicle starts to rise sharply, and the increase in the vehicle interior pressure can be suppressed.

According to the fourth aspect of the present invention, the glass breaking actuator can be activated when the operation switch is operated by an occupant or the like, regardless of the airbag system, to break the window glass of the vehicle. . Therefore, when a vehicle accident occurs, the occupant can operate the operation switch to destroy the window glass of the vehicle and escape from the opening of the window glass, so that the occupant may be trapped in the passenger compartment. Can be avoided.

According to the fifth aspect of the present invention, when the vehicle falls into the water, the glass breaking actuator is activated by the water sensor provided in the vehicle regardless of the airbag system. Destroy vehicle windows. Therefore, when a vehicle is submerged, the water sensor and the glass breaking actuator are automatically activated and the window glass of the vehicle is broken, so that the occupant can easily escape from the window glass opening to the outside. Can be
The danger of being trapped in a submerged vehicle interior can be avoided.

According to a sixth aspect of the present invention, there is provided a glass breaking actuator which is activated simultaneously with the airbag system and breaks the window glass, the glass breaking actuator being activated by the manually operated operation switch, or Since it also serves as a glass breaking actuator activated by the water sensing sensor, there is no need to provide another glass breaking actuator for each application, and the number of glass breaking actuators can be reduced, the configuration can be simplified, and the cost can be reduced.

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a side view of a vehicle equipped with a vehicle window glass breaking device according to an embodiment of the present invention, and FIG. 2 is a first operation of the embodiment, in which an increased pressure in the cabin during operation of an airbag is released to the outside of the vehicle. 3 and 4 are operation system diagrams showing the operation and control flow at that time, and FIG. 5 is a flowchart showing the control procedure.

In FIG. 1, reference numeral 1 denotes an electronic control unit, which basically receives a signal from a collision detection sensor 2 so that a front airbag Ba and a rear airbag B are input.
It has functions such as the determination of the operation timing such as b and the distribution of commands. H indicates wiring for transmitting a signal from the control device 1 to each device. The apparatus of the above embodiment is characterized in that, as shown in FIG.
Window glass breaking actuator Aa directly on Ce or on the frame of the vehicle window supporting them, etc.
-Ae, and a switch 3 that can be operated by an occupant in the passenger compartment, and a water sensor 4.

The first operation of the illustrated embodiment is as follows. The collision detection sensor 2 shown in FIG. 1, the airbag control, the electronic control device 1 as a signal judgment and distribution module, the airbags Ba and Bb, Further, it is performed by window glass breaking actuators Aa to Ae. That is, FIG.
When the vehicle receives a signal from the collision sensor 2 when the vehicle collides as shown in FIG.
a, Bb are expanded, but simultaneously or with a predetermined time control, the window glass breaking actuators Aa-A.
e to destroy the window glasses Ca to Ce of each part. At this time, the window glasses Ca to Ce broken at this time, as shown in FIG.
e and scatters, and at the same time, the pressure in the vehicle interior and the inflator gas are also released outside the vehicle as shown by the arrow, so that a rapid pressure increase in the vehicle interior is prevented, and the inflator gas does not stay in the vehicle interior. . Window glass fragments G
If the glasses Ca to Ce to be used are selected so that a to Ge have a spherical shape with little danger, the danger to the outside can be suppressed.

This basic first operation of the illustrated embodiment will be described in more detail. As shown in FIG. 3, the control system 1 receives a signal when the collision sensor 2 detects a collision, sends a signal to an ignition device 5 of the airbag system, ignites the inflator 6, and activates the airbag Ba. ~ Bb is developed. On the other hand, in parallel with the control of the deployment of the airbag, the control device 1 controls the window glass breaking actuators Aa to AA.
e to destroy at least a part of the window glasses Ca to Ce of the vehicle. As a result, the vehicle interior is opened to the atmosphere, and the vehicle interior pressure is released outside the vehicle.

As a modification of the first operation system, FIG.
As described above, in the control of the deployment of the airbag and the destruction of the window glass, the controller 1 selects the deployment position of the airbag from the selection of the deployment position of the airbag in consideration of the number of occupants in the vehicle interior and the presence / absence of a side collision. Control such as selection of the position and the number of destructions may be performed. FIG. 5 shows an example of a flowchart of the determination and control by the control device 1 at that time. In this example, the number of occupants, the state of frontal collision, and side collision are used as judgment materials, and when the number of deployed airbags is two or less, it is judged that the influence of the cabin pressure on the occupant is small, and the window glass is broken. Only one window glass Aa of the driver's seat necessary for rescue of the occupant. If the number of deployed airbags is three or more, it is determined that the influence of the cabin pressure on the occupant is large, and all window glasses Ca to Ce are destroyed. Thus, control is performed to release high pressure inside the vehicle compartment to the outside of the vehicle within a short time. However, this control is merely an example, and it is possible to control the position and number of the deployment of the airbag and the breakage of the window glass from one place to all places from more conditions.
Further, it is preferable that time control is added to each of the deployment of the airbag and the destruction of the window glass, and the control is performed in consideration of the time difference from the deployment to the destruction. In addition, although the front glass is excluded in the illustrated example, it can be added to the object of destruction if necessary.

Next, a second operation of the illustrated embodiment will be described. This function enables the occupant to escape from the door of the vehicle due to the deformation of the car body due to a collision accident, etc., and when the occupant is trapped in the passenger compartment, it can escape and rescue. Of the configurations shown, in particular, one to several operation switches 3 provided in the passenger compartment, the control device 1, and the window glass breaking actuators Aa to Ae are operated. That is, when the occupant determines that it is difficult to escape from the vehicle, the occupant presses the operation switch 3 so that the control device 1 that has received the signal of the operation switch sends a signal to the window glass breaking actuators Aa to Ae, Window glass C
At least one of a to Ce is destroyed, and the occupant can escape and rescue from the window.

FIG. 6 shows an operation system of the second operation which is useful for occupant escape and rescue. That is, the control device 1 which receives the signal of the operation switch 3 operated by the occupant sends the distributed signal to the window glass breaking actuators Aa to Ae of the vehicle to break the window glass of the window where the occupant can escape and rescue. And escape from the vehicle window and rescue. In addition, as shown in FIG. 7, a judgment control in consideration of the position of the switch operated by the occupant, the position of the occupant, and the like is added to this operation system diagram,
Window glass destruction control, such as destruction of the window glass closest to the occupant, may be performed.

FIG. 8 shows an example of a flowchart of the judgment and control by the control device 1 at that time. In this determination and control example, the position where the pressed operation switch 3 is installed is
Based on the position of the occupant, control is performed so that the window glass closest to the pressed operation switch 3 and the window glass closest to the position where the occupant is located are destroyed. However, this control is merely an example, and it is possible to control the breaking position and the number of windowpanes from one place to all places under more conditions as in the case of the airbag pressure adjustment described above. is there. Further, it is preferable to add occupant alert control to the control or to perform occupant escape and rescue control in consideration of the time difference in destruction of the window glass.

Next, a third operation of the illustrated embodiment is that in the event of a water submergence in a river or sea, the water pressure makes it difficult to open and close a vehicle door and a vehicle window, and it is difficult for an occupant to escape. This is an action that enables escape and rescue when predicted. This operation is performed by one or several water sensing sensors 4 and control device 1 mounted in the vehicle shown in FIG. 1 and window glass breaking actuators Aa to Ae. The water sensor 4 is a sensor capable of detecting the presence or absence of moisture, and is attached to a place in a vehicle interior of a vehicle where rainwater or the like cannot normally enter, for example, behind a vehicle interior meter panel.

According to the above configuration, when the vehicle is submerged to a predetermined level, a signal is output from the water sensor 4 shown in FIG. 1, and the control device 1 having received the signal determines that the vehicle is submerged. Then, when the danger of the occupant is predicted, a signal is sent to the window glass breaking actuators Aa to Ae to break the window glass Ca to Ce, thereby enabling the occupant to escape and rescue from the window.

As shown in FIG. 9, the third operation system when the occupant escapes is that the control device 1 which has received a signal output from the water sensor 4 causes the window glass breaking actuators Aa to.
A signal is distributed to Ae and a signal is sent to break the window glass of the occupant's escapeable window, enabling escape and rescue from the vehicle window.
Further, as shown in FIG. 10, judgment control considering the position of the water sensing sensor 4 with respect to the vehicle, the position of the occupant, the inclination of the vehicle, and the like is applied to the operation system diagram, and the window glass at the position closest to the occupant is added. Alternatively, selective window glass destruction control may be performed, such as destroying an upper window glass with respect to the inclination of the vehicle.

FIG. 11 shows an example of a flowchart of the judgment and control by the control device 1 at that time. In this judgment control,
From the position of the water sensing sensor 4 with respect to the vehicle and the position of the occupant on the opposite side to the position of the water sensing sensor 4 from the position of the occupant or the inclination of the vehicle,
In addition, control is performed to destroy the window glass above the inclination of the vehicle, that is, the position where it is expected that the vehicle is not yet completely submerged with respect to the submerged position of the vehicle, and at the position near the occupant. I have. However, the control shown is 1
It is only an example, and like the first and second operations described above,
From more conditions, etc., determine the location and number of window glass breakage,
It is also possible to control from one location to all locations. In addition, it is preferable to perform the occupant escape and rescue control in consideration of the occupant's attention control for the control and the time control for the destruction of the window glass.

Although the three operations according to the embodiment of the present invention have been described above, the system can be mounted on a vehicle as a system having any one or two operations. In that case, it goes without saying that the configuration becomes simpler. But,
It can be said that mounting a plurality of systems that perform as many operations as possible is preferable from the viewpoint of protecting, escaping, and rescuing the occupants of the vehicle. In addition, since actual modes of vehicle accidents are various, it goes without saying that there are cases where the window glass of the vehicle needs to be destroyed in addition to the actions of the above three examples.

[0034]

EXAMPLES Next, two examples will be described of window glass breaking actuators Aa to Ae of a vehicle which can be used as a part of the above embodiment. First, a window glass breaking actuator 30 according to the first embodiment applies a shock to a cross section formed on a window glass by using expansion and contraction of a PZT stack. As shown in FIG. Has a structure in which a PZT stack 32 is fixed inside, and a hammer portion 33 is slidably inserted coaxially with the PZT stack 32. The actuator 30 is supported by a glass retainer 35 and an adjustment nut 36 supported thereon and threadedly engaged with a male thread formed in a portion of the actuator body 31 so that they are in place on the lower edge of the vehicle window glass. It is inserted into the concave portion 37 provided near the glass support mechanism, and is set so that the hammer portion 33 and the glass retainer 35 are in close contact with each other. In this state, as shown in FIG. 13, a window glass breaking signal is sent from the control device 1 to the PZT stack 32, and the PZT stack 32 is instantaneously extended, whereby the hammer 33 is pushed out and the window glass 34 is pushed. The impact in both directions is applied to break a portion of the glass. As a result, the window glass 34, which is merely a tempered glass, is partially broken and the entire window glass is cracked. proceed.

The window glass breaking actuator 38 of the second embodiment applies a shock to the glass flat portion of the window glass using the pressure of gas generated by the inflator.
As shown in FIG. 4, an inflator 40 is mounted in a bottomed cylindrical inflator cylinder 39, a piston-shaped hammer 41 is inserted on the same axis, and an ignition device 43 is attached to the inflator 40. The actuator 38 is fixed on the plane of the window glass 42, for example, at a position in the door body that cannot be seen from the outside.
In this state, as shown in FIG. 15, a window glass breaking signal is sent from the control device 1 to the ignition device 43, and the explosive of the inflator 40 is ignited to generate inflator gas. A portion of the glass is broken by extruding 41 and impacting the window glass 42. As a result, part of the window glass 42, which is simply tempered glass, is broken to progress to cracks in the entire window glass, and further, the entirety of the window glass is broken by the inflation of the airbags Ba and Bb.

Although two examples of the vehicle window glass breaking actuator that can be used in the embodiment of the present invention have been described above, another example is to break the window glass of the vehicle in an extremely short time. As long as it can be reached, for example, a device using a tensile spring, a magnet solenoid, or the like may be used, and further, there are various embodiments such as a combination thereof. Also, regarding the destructive action on the window glass of the vehicle, in addition to the actuator directly acting on the window glass of the vehicle, indirectly acting via a frame or the like to destroy the window glass, or in the form of destruction. Needless to say, in addition to the crushing of the window glass, the sealing function of the window glass of the vehicle may be completely eliminated by removing the glass from the vehicle window frame.
