<First Embodiment>
1 and 2 are schematic views showing the configuration of the vehicle 1 in the first embodiment of the present invention. FIG. 1 shows a side view of the vehicle 1, and FIG. 2 shows a plan view of the vehicle 1. In FIG.1 and FIG.2, arrangement | positioning on the vehicle of each structure of the protection apparatus 5 is illustrated. In the present embodiment, the vehicle 1 is a four-door sedan type four-wheeled vehicle. However, the present invention is also applicable to four-wheeled vehicles other than the sedan type and other types of vehicles. 1 and 2, the arrow X indicates the front-rear direction of the vehicle 1, the arrow Y indicates the vehicle width direction of the vehicle 1, and the arrow X indicates the vertical direction of the vehicle 1. Yes.

The vehicle 1 is roughly divided into a front part 1a, a middle part 1b, and a rear part 1c as shown in FIGS. For example, a drive unit such as an engine or a transmission is accommodated in the front portion 1a. The front part 1a is provided with a hood (front hood) 3 as an exterior covering the internal accommodation space. A cowl (outer plate portion) 22 between the hood 3 and the front windshield 21 is provided with a wiper base and a ventilator air inlet. Below the hood 3 (the front surface of the vehicle 1), a bumper 23 is provided as a buffer portion for reducing and absorbing the impact of the collision. The central part 1b constitutes a guest room. The rear part 1c constitutes a trunk, for example.

The protection device 5 is a vehicle protection device that constrains a collided object that collides with the vehicle 1 to the vehicle and protects it. The protection device 5 includes a storage unit 10. FIG. 1 schematically shows the structure of the storage unit 10. The storage unit 10 is a unit for storing the airbag 11. In the present embodiment, the storage unit 10 is built (stored) below the front windshield 21 of the vehicle 1, specifically, in the cowl 22.

The storage unit 10 has a housing 10a and a cover 10b that constitute the outer wall thereof. The casing 10a has an opening on the front side (the front side of the vehicle 1), and the cover 10b is attached to the casing 10a so as to close the opening of the casing 10a. When the airbag 11 is deployed, the cover 10b is configured to be separated from the housing 10a by the urging force of deployment or to be broken.

The airbag 11 is stored in the storage unit 10 in a folded state (stored state). The airbag 11 has a fixed end portion 11a fixed to the deployment unit 12 (vehicle 1). For example, the airbag 11 is deployed (inflated) in a bag shape from the fixed end portion 11a in the deployed state. The airbag 11 is made of a material having flexibility and heat resistance as a whole.

The expansion unit 12 is provided in the storage unit 10. The deployment unit 12 deploys the airbag 11 from the stored state stored in the vehicle 1 to the front of the vehicle 1. The deployment unit 12 is, for example, a unit that injects air and deploys the fabric airbag 11 by air pressure, and specifically includes a gas pressure generating device such as an inflator. When the deployment unit 12 is actuated, the airbag 11 is ejected from the storage unit 10 while inflating the cover 10b, and is expanded to the outside of the vehicle 1. In the present embodiment, as shown in FIG. 2, the airbag 11 is deployed forward of the vehicle 1 by the deployment unit 12 and is configured to cover the entire hood 3 of the vehicle 1 in the deployed state. The injection direction of the airbag 11 can be set by the configuration and arrangement of the casing 10a, the arrangement of the deployment unit 12, and the like.

The protection device 5 further includes a sensor 14 and an EUC 15. The sensor 14 is a sensor that detects a collision target, and includes, for example, an object detection sensor that detects an object around the vehicle 1 and a contact detection sensor that detects that an object has contacted (collised) the vehicle 1. Examples of the object detection sensor include a camera and a radar. Examples of the contact detection sensor include an acceleration sensor, a pressure sensor, a touch sensor and the like in addition to the object detection sensor. In the present embodiment, the sensor 14 is disposed on the front portion 1a of the vehicle 1, specifically, the front surface of the vehicle 1, but is not limited thereto. For example, the sensor 14 may be disposed in a portion other than the front surface of the vehicle 1 or a plurality of sensors 14 may be disposed.

The ECU 15 is a control unit that controls the deployment unit 12 based on the detection result of the sensor 14. The ECU 15 includes, for example, a processor such as a CPU, a storage device such as a RAM and a ROM, and an interface with an external device. The processor executes a program stored in the storage device. For example, when the ECU 15 determines from the detection result of the sensor 14 that the vehicle 1 has collided with the colliding object, or when it is determined that the vehicle 1 is highly likely to collide with the colliding object (predicted collision). Case), the deployment unit 12 is actuated. The ECU 15 determines whether or not the collision target is a human (for example, a pedestrian) from the detection result of the sensor 14, and when determining that the collision target is a human, the ECU 15 When it is determined that the collision target is not a human, the deployment unit 12 can be controlled so that the deployment unit 12 is not activated.

In this embodiment, an ECU 15 is interposed between the sensor 14 and the deployment unit 12. However, it is also possible to employ a configuration in which the deployment unit 12 is operated by directly inputting an electrical signal (detection signal) from the sensor 14 to the deployment unit 12 without interposing the ECU 15 between the sensor 14 and the deployment unit 12.

An example of the operation of the protective device 5 will be described with reference to FIGS. FIG. 3 shows a state where the vehicle 1 and the collision target 100 collide. Here, the collision object 100 is assumed to be a human. As shown in FIG. 3, when the sensor 14 detects that the collision object 100 has collided with the vehicle 1, the ECU 15 operates the deployment unit 12. As a result, as shown in FIG. 4, the airbag 11 is instantly deployed from the cowl 22 to the front of the bumper 23 (that is, so as to cover the entire hood 3 and the entire front surface of the bumper 23).

FIG. 5A is a view showing the airbag 11 in a deployed state. As shown in FIGS. 5A and 5B, the airbag 11 is provided with a coupling member 31 that is coupled to each other so as to capture the collision target. The coupling member 31 is disposed at least on the front surfaces on both sides in the vehicle width direction of the vehicle 1 of the collision target 100 of the airbag 11 in the deployed state. For example, as illustrated in FIG. 5A, the coupling member 31 is continuously extended from one end portion in the vehicle width direction of the vehicle 1 to the other end portion of the airbag 11 in the deployed state.

When the collision object 100 collides with the airbag 11 in the deployed state from the front, the airbag 11 is deformed so as to wrap the collision object 100 as shown in FIG. 5B, and at least both ends of the airbag 11. The coupling members 31 provided on the front side surfaces are coupled to each other. As a result, the impacted body 100 is in a state of being wrapped in the airbag 11 in front of the bumper 23 and on the hood 3 (that is, captured by the airbag 11), and the impacted object 100 falls to the road surface. Damage can be suppressed. FIG. 5B is a diagram illustrating the airbag 11 in a state where the coupling members 31 are coupled to each other.

As described above, in this embodiment, as shown in FIGS. 6A and 6B, the collision object 100 can be restrained to the vehicle 1. 6A is a side view of the airbag 11 in a deployed state, and FIG. 6B is a perspective view of the airbag 11 in a state in which the coupling members 31 are coupled to each other. Although the position and posture of the collision object 100 at the time of the collision are various, by using the airbag 11 provided with the coupling member 31, the collision object 100 can be wrapped and captured by the airbag 11. In addition, since the airbag 11 is deformed in accordance with the posture of the collision target 100, it is possible to cope with various postures of the collision target 100.

Here, the coupling member 31 is a flexible member, and is composed of, for example, a hook-and-loop fastener or a tape-shaped magnet. The collision object 100 can be captured at an arbitrary position of the coupling member 31 in the vehicle width direction. When the coupling member 31 is a hook-and-loop fastener, the airbag 11 is also coupled to the clothing of the collision target 100 in a state where the airbag 11 wraps around the collision target 100, that is, in a state where the coupling members 31 are coupled to each other (FIG. 5B). The member 31 is combined and the restraining force of the collision target 100 by the airbag 11 can be improved. Moreover, the coupling member 31 may be comprised by the some strip | belt-shaped surface fastener 31a. For example, as shown in FIG. 7, the plurality of belt-shaped surface fasteners 31 extend in the vehicle width direction of the airbag 11 in the deployed state and are spaced apart in the vertical direction of the vehicle 1. Thereby, when the vehicle 1 and the collision object 100 collide, the collision object 100 can be reliably captured by the airbag 11.

Further, it is preferable to provide a coupling member coupled to each other on the inner surface of the airbag 11 as well. Specifically, as shown in FIGS. 8A and 8B, the coupling member 41a is disposed on the front inner surface of the airbag 11 in the deployed state, and the coupling member 41b is disposed on the rear inner surface of the airbag 11 in the deployed state. The

coupling members

41a and 41b are members having flexibility similarly to the coupling member 31, and are constituted by, for example, a hook-and-loop fastener or a tape-shaped magnet. FIG. 8A is a diagram illustrating the airbag 11 in the deployed state, and FIG. 8B is a diagram illustrating the airbag 11 in a state where the coupling members 31 are coupled to each other. As described above, the collision object 100 collides with the airbag 11 in the deployed state from the front, so that the airbag 11 is deformed so as to wrap the collision object 100 as shown in FIG. The coupling members 31 provided on the front surfaces of both ends of the bag 11 are coupled to each other. At this time, the coupling member 41a provided on the front inner surface of the airbag 11 and the coupling member 41b provided on the rear inner surface of the airbag 11 are similarly coupled to each other. As described above, since the

coupling members

41 a and 41 b are coupled to each other even inside the airbag 11, the amount of movement of the airbag 11 due to the behavior of the vehicle 1 can be suppressed. 100 restraining force can be improved.

Also, a mechanism for fixing the airbag 11 deployed forward of the vehicle 1 to the vehicle 1 (hood 3) may be provided. Specifically, as shown in FIGS. 9A and 9B, a magnet 51 is disposed in a portion of the airbag 11 adjacent to the hood 3 of the vehicle 1 in the deployed state. FIG. 9A is a diagram showing the airbag 11 in the deployed state, and FIG. 9B is a diagram showing the airbag 11 in a state where the coupling members 31 are coupled to each other. For example, the magnet 51 is disposed at least on the rear surface of both ends in the vehicle width direction of the airbag 11 in the deployed state. However, the magnet 51 may be disposed between the rear inner surface of the airbag 11, more specifically, between the inner inner surface of the airbag 11 and the coupling member 41b. Since the hood 3 of the vehicle 1 is generally made of iron, the airbag 11 can be fixed to the vehicle 1 by attracting the magnet 51 to the hood 3. If the hood 3 of the vehicle 1 is made of resin, a member to which the magnet 51 is attracted may be additionally provided in the vehicle 1. As described above, since the airbag 11 deployed in front of the vehicle 1 is fixed to the hood 3 of the vehicle 1, the amount of movement of the airbag 11 due to the behavior of the vehicle 1 can be suppressed. 11 can improve the restraining force of the collision target 100.

10A and 10B, the airbag 11 is provided with a vent hole 61 for adjusting the internal pressure of the airbag 11. FIG. 10A is a diagram illustrating the airbag 11 in the deployed state, and FIG. 10B is a diagram illustrating the airbag 11 in a state where the coupling members 31 are coupled to each other. The vent hole 61 is closed in the state shown in FIG. 10A, and the pressure inside the airbag 11 is maintained at a certain level or higher. This is because if the pressure inside the airbag 11 is not maintained above a certain level, the deformation amount of the airbag 11 at the time of the collision of the collision target 100 is insufficient (that is, the airbag 11 does not enter the collision target 100). This is because the coupling members 31 provided on the front surfaces of the both end portions of the airbag 11 cannot be coupled to each other. On the other hand, in the state shown in FIG. 10B, the vent hole 61 is released. As a result, the wraparound performance of the airbag 11 with respect to the collision object 100 can be adjusted. In addition, it is possible to reduce the pressure inside the airbag 11 after the collision of the collision target 100 and secure a breathing space for the collision target 100.

Second Embodiment
FIG. 11 is a schematic diagram showing the configuration of the vehicle 1 in the second embodiment of the present invention. In the present embodiment, the vehicle 1 includes a protection device 70 in addition to the protection device 5. The protection device 70 is a vehicle protection device that restrains a collision object that collides with the vehicle 1 with the vehicle and protects it. The protection device 70 includes a storage unit 71 as with the protection device 5. The storage unit 71 is a unit for storing the airbag 72. In the present embodiment, the storage unit 71 is stored in the lower front of the hood 3 of the vehicle 1.

The airbag 72 is stored in the storage unit 71 in a folded state (stored state), like the airbag 11. The airbag 72 has a fixed end portion that is fixed to the vehicle 1. As shown in FIG. 12A, for example, the airbag 72 is deployed (inflated) in a bag shape from the fixed end in the deployed state.

The storage unit 71 is provided with a deployment unit 73. As shown in FIG. 12A, the deployment unit 73 deploys the airbag 72 from the stored state stored in the vehicle 1 to the front of the vehicle 1. In the present embodiment, the airbag 72 is deployed in front of the bumper 23 of the vehicle 1 by the deployment unit 73. Therefore, the airbag 11 is deployed on the upper side of the vehicle 1 relative to the airbag 72, and the airbag 72 is deployed on the lower side of the vehicle 1 relative to the airbag 11.

In this embodiment, the ECU 15 controls the

deployment units

12 and 73 based on the detection result of the sensor 14. For example, when the ECU 15 determines from the detection result of the sensor 14 that the vehicle 1 has collided with the collision target, or when it is determined that the vehicle 1 is highly likely to collide with the collision target, the deployment unit 12 And 73 are activated.

An example of the operation of the protection devices 5 and 70 will be described with reference to FIGS. 12A and 12B. As shown in FIG. 12A, when the sensor 14 detects that the collision object 100 has collided with the vehicle 1, the ECU 15 operates the

deployment units

12 and 73. Thereby, as shown in FIG. 12A, the airbag 11 is deployed on the hood 3 of the vehicle 1, and the airbag 72 is deployed in front of the bumper 23 of the vehicle 1.

FIG. 12B is a diagram showing the

airbags

11 and 72 in a deployed state from the front. As shown in FIG. 12B, the airbag 72 is provided with a coupling member 74 that couples to each other in the same manner as the airbag 11. The coupling member 74 is disposed at least on the front surfaces of both ends of the airbag 72 in the vehicle width direction of the vehicle 1 in the deployed state. The coupling member 74 extends continuously from one end portion to the other end portion in the vehicle width direction of the vehicle 1 of the airbag 11 in the deployed state. In this embodiment, the coupling member 74 is composed of a plurality of strip-shaped surface fasteners that are spaced apart in the vertical direction of the vehicle 1.

Thus, in this embodiment, by deploying the airbag 11 over the cowl 22 and the hood 3, for example, the airbag 11 wraps from the head to the waist of the collision target 100, and the airbag 72 is made to be a bumper. For example, the leg portion of the collision target 100 can be wrapped with the airbag 72. Thereby, when the vehicle 1 and the collision object 100 collide, the collision object 100 can be reliably captured by the

airbags

11 and 72. Further, when the collision object is a child, the collision object 100 can be reliably captured by the airbag 72. As described in the first embodiment, a coupling member coupled to each other may be provided on the inner surface of the airbag 72, or the airbag 72 deployed forward of the vehicle 1 may be provided in the vehicle 1 (bumper 23). A mechanism for fixing the air bag 72 may be provided, or a vent hole for adjusting the internal pressure of the airbag 72 may be provided.

Further, the vehicle 1 may include only the protection device 70 without including the protection device 5. In such a case, as shown in FIG. 13, the airbag 72 may be deployed not only in front of the bumper 23 but also in front of the front windshield 21.

As mentioned above, although preferable embodiment of this invention was described, it cannot be overemphasized that this invention is not limited to these embodiment, A various deformation | transformation and change are possible within the range of the summary.
