Abstract

PURPOSE:To protect a crew from the direct hit of a boat by providing an air bag enclosed in a part of a hull near a manipulator's seat, and making the air bag expand and develop receiving high pressure gas from an inflator and stand up on the hull to form a screen, thereby eliminating an obstruction entering into the manipulator's seat. CONSTITUTION:At the time of predicting the danger of a collision, a command is sent out to a spark plug 9 from a manipulator's seat 2 by the operation of a push button or a handle at a manipulator's seat 2, and the spark plug 9 is ignited to ignite the explosive of a gas generator 8. High pressure gas generated by the explosion of the explosive is blown into an air bag 5 from the gas exhaust holes 11 of an inflator 7. The air bag 5 expands and develops immediately upon receiving high pressure gas and makes a cover 12 jump up, and the air bag 5 stands up on a deck 4 to form a screen. The tip of a colliding boat is thereby stopped by the expanded-developed air bag 5 so as to avoid at least such a dangerous state as to go over a cowling to directly hit the manipulator's seat 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motor boat, and more particularly to a structure of a planing boat for high speed racing.

[0002]

2. Description of the Related Art A planing boat (hereinafter abbreviated as a boat) slides on the water surface at a high speed comparable to that of an automobile, and therefore has a flat bottom.

In boat competitions, collision accidents frequently occur, especially when cornering. In FIG. 6, when the leading boat 1 and the trail of the trailing boat 1 ′ intersect with each other, the trailing boat 1 ′ does not stop merely contacting or colliding with the leading boat 1 and the bottom of the boat is flat, so There is a risk that the boat 1 ′ rides on the preceding boat 1 and further passes over the preceding boat 1 and directly hits an occupant of the preceding boat 1.

The occupant of the boat who has been directly hit is in danger of being caught in the screw of the boat in addition to the risk of impact and water drop due to the direct hit.

[0005]

However, in preparation for a collision accident, the boat is provided with a cushioning rising portion called a cowling on the deck so as to reduce the impact force at the time of collision, and the occupant is provided with the means. Although we try to reduce injury by wearing protective clothing and helmets, it is unprotected against collision accidents where the boat crosses the cowling and directly hits the human body, and it is necessary to ensure the safety of passengers in boat competitions. It has been called more strongly than before.

An object of the present invention is to provide a motor boat capable of preventing one boat from riding on the other boat in the event of a boat collision and effectively protecting an occupant from a direct hit of the boat.

[0007]

In order to achieve the above object, the motor boat according to the present invention is a motor boat having an air bag, the air bag being housed in a part of the hull in the vicinity of the cockpit, and having a high pressure from the inflator. It receives gas, expands and deploys it, rises on the hull, forms a screen, and eliminates obstacles that enter the cockpit.

Further, the hull has a stop plate, and the stop plate supports the rising portion of the inflated and deployed airbag from the inside,
It prevents the airbag from falling into the cockpit.

Further, the airbag has a vent hole, and the vent hole is an opening for discharging the high pressure gas into the outside air after inflating and expanding.

[0010]

[Operation] In a boat race, when the course of the preceding boat intersects with the course of the following boat during cornering,
It is said that the pilot of the leading boat can predict the occurrence of a collision accident in advance. When predicting the occurrence of an accident, the pilot of the preceding boat manually operates the inflator, and the airbag instantaneously inflates and expands to form a screen, which prevents the subsequent boat from crossing the course from entering. At the same time, the cushioning effect of the airbag cushions the shock and protects the occupant in the cockpit.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a planing bottom of a planing boat (boat) 1 is flat, and a smooth curved surface is connected from the ship tip to the bottom. As shown in FIGS. 2 and 3, cowlings 3 are provided on both sides of the cockpit 2.

The cowling 3 is attached to the deck 4,
It is a rising portion that protects the occupant in the cockpit 2 in the event of a collision. However, the rising height of the cowling 3 is insufficient to prevent the boat on the other side of the collision from getting over.

According to the present invention, an airbag 5 is mounted on a hull and inflates and deploys in an emergency to form a screen, which is normally folded into a small volume and stored in the hull.
In the embodiment, as shown in FIG. 2, an example in which the airbag 5 is provided on the deck 4 obliquely behind the cockpit 2 is not limited to the deck 4 but may be provided on the cowling 3.

FIG. 4 shows an air bag storage structure. Figure 4
In, a cylindrical inflator 7 is installed in the housing 6, and a gas generator 8 filled with explosive is placed in the inflator 7.
Is decorated. The gas generator 8 is ignited by an ignition plug 9 which is operated by an operation from the cockpit 2. Multiple filters 10 are interposed between the gas generator 8 and the inflator 7, and a large number of gas ejection holes 11 are opened on the upper peripheral surface of the inflator 7 facing the inside of the housing 6. On the other hand, the airbag 5 is a bag body having an opening on one surface, and the opening is communicated with the gas ejection hole 11 of the inflator 7 and folded in multiple layers to be stored in the housing 6.

The housing 6 is installed in the deck as shown in FIG. 2, and the top opening is covered with the cover 12.

The airbag 5 is not particularly limited in its material as long as it is a bag shape that can be folded and can be easily deployed. Usually, a sheet used for a vehicle airbag, for example, a synthetic sheet. Textile fabrics, high-density fabrics, heat-resistant and strength-resistant fabrics, and sheets obtained by coating these fabrics with various resins and rubbers can be used. Further, in order to process the sheet into a bag shape, any of sewing, bonding, fusing, welding and the like can be performed.

FIG. 5 shows an example of the shape of the airbag 5 when inflated and deployed. The airbag 5 is shaped into a vertically-long rectangular three-dimensional shape that rises upward with a constant width and length, but a hanging cloth that suppresses expansion between the seat surfaces of the airbag in order to shape it in a fixed shape (illustration). May be attached. Further, the vent hole 13 is opened on the seat surface in order to control the expansion connection time.

In the embodiment, when the danger of collision is predicted, a command is issued from the cockpit 2 to the spark plug 9 by operating the push button or the handle of the cockpit 2, and the ignition plug 9 is ignited to ignite the explosive charge of the gas generator 8. The high-pressure gas generated by the explosion of the explosive is ejected into the airbag 5 through the gas ejection holes 11 of the inflator 7. The airbag receives the high-pressure gas, immediately expands and deploys, and flips up the cover 12 to stand up on the deck 4 to form a screen. Therefore, as shown in FIG. 6, the tip of the boat 1'which has collided is received by the inflated and expanded airbag 5, and the dangerous situation of at least overcoming the cowling 3 and hitting the cockpit 2 directly can be avoided. Further, due to the cushioning function of the airbag 5, the impact of the collision received by both boats can be minimized.

When the seat surface of the airbag 5 collides with the destination of the other boat, the impact force of the airbag 5 may cause the airbag 5 to collapse toward the cockpit 2 depending on the shape of the airbag. To be In order to prevent the airbag 5 from collapsing, it is effective to support the inner surface of the airbag 5 with a stop plate 14 having a constant height as shown in FIG. When the base portion of the airbag 5 is supported by the stop plate 14, the repulsive force is increased and the boat 1'which has collided can be repelled. However, the stopper plate 14 does not necessarily have to be separately attached, and the outer surface of the cowling 3 may be used, or when the cover 12 of the housing 6 is flipped up, it is erected vertically to make it stop. You may use it for.

When the air bag 5 is provided with the vent hole 13, the high pressure gas is exhausted through the vent hole 13 at the same time when the air bag 5 is inflated and deployed.
It rapidly withers under the impact of a collision, and resistance on the sideline is minimized.

[0021]

As described above, according to the present invention, when a danger is sensed, the airbag is inflated and deployed to form a screen. Therefore, when a post-collision event actually occurs, the front end of the boat that has collided Can be received by the seat surface of the airbag, which can prevent passengers from entering the cockpit and ensure the safety of the occupant.Because the airbag has a cushioning property, the shock received by the occupant from the impact of a collision can be secured. It can be minimized to prevent accidents due to recoil and accidents of falling water. Although the embodiment has been described with reference to an example applied to a planing boat, the present invention is not limited to this, and has the effect that it can be widely used as a cushion for cushioning the impact of a general motor boat collision by selecting the installation position of the airbag.
