<First embodiment>
A vehicle safety device according to a first embodiment of the present invention will be described below with reference to FIGS. 1 to 5. FIG.

As shown in FIG. 1, a vehicle safety device 100 is provided inside a vehicle, and includes an equipment 10, a connection member 11 such as a string member or a wire whose surface is covered with a soft member such as rubber, and a winding. and a pick-up device 12 .

As shown in FIGS. 1 and 2, the equipment 10 can be attached to the torso of a vehicle occupant P1. Further, as shown in FIG. 2( a ), the brace 10 is a belt member 1 , a buckle 2 attached to one end of the belt member 1 , and attached to the other end of the belt member 1 and coupled to the buckle 2 . A detachable connecting portion 3 and a pair of ring portions 4 provided in the middle of the belt member 1 are provided. In addition, FIG. 2(a) is a front view of the passenger to whom the brace 10 is attached, and FIG. 2(b) is a rear view of the passenger to which the brace 10 is attached.

One end of the connecting member 11 can be attached to the ring portion 4 as shown in FIG. The other end of the connecting member 11 is connected to the winding device 12 .

The winding device 12 is provided below the side of the seat 13 as shown in FIG. The winding device 12 also includes a support base 21, a servomotor 22, a reel shaft 23, a reel 24, and a lock mechanism 25 inside.

The support base 21 is fixed to the seat 13 . The servo motor 22 is fixed to one end side of the support base 21 and has an output shaft integrated with one end of the reel shaft 23 . The other end of the reel shaft 23 is coupled to and integrated with a winding shaft 32 of a lock mechanism 25, which will be described later. The reel 24 is rotatably supported around the reel shaft 23 . With these configurations, each winding device 12 can be operated by the servomotor 22 to wind the connecting member 11 onto the reel 24, to feed (unwind) the connecting member 11 from the reel 24 as a delivery mechanism, or to perform a predetermined length ( For example, an operation for adjusting the extension length of the connection member 11 is appropriately performed so that the connection member 11 is not extended beyond a length that can avoid a collision with relatively hard equipment in the vehicle. can be done.

As shown in FIGS. 4A and 4B, the lock mechanism 25 includes a winding shaft 32 connected to the reel 24 via the reel shaft 23, a rotating member 33 having a plurality of rotating teeth 33a, and a plurality of rotating teeth 33a. and a gas generator 31 capable of moving the moving member 34 along the inner wall of the cylindrical member 36 by the generated gas pressure. It is provided on the side of the side.

The rotating member 33 is provided in a box-shaped case 35 and fixed to the tip of the winding shaft 32, and rotates in the same direction when the winding shaft 32 rotates about its axis. That is, when the rotating member 33 rotates in the direction of the arc arrow shown in FIG. 4A, the winding shaft 32 and the reel shaft 23 can be rotated in the winding direction.

The moving member 34 is slidably inserted in a cylindrical member 36 that is closed at one end and communicates with the inside of the case 35 at the other end. Inside the tubular member 36 , the gas generator 31 is provided at a position facing the moving member 34 , and a space 37 is provided between the moving member 34 and the gas generator 31 . This space 37 is supplied with the gas generated in the gas generator 31 . Then, the moving member 34 is moved toward the rotating member 33 by using gas pressure, so that the moving teeth 34a are meshed with the rotating teeth 33a, and the rotating member 33 moves in the direction of the arc arrow shown in FIG. 4(a). It can be rotated. Therefore, in the lock mechanism 25, the winding shaft 32 and the reel shaft 23 are rotated in the winding direction by the operation of the gas generator 31, thereby winding the coupling member 11 on the reel 24 by a predetermined length and 32 and the reel shaft 23 can be locked (prevented from rotating) for a predetermined time.

Here, the gas generator 31 is small and lightweight, and includes a cup body filled with a gas generating agent, an igniter for igniting the gas generating agent, and a holder for holding the igniter. be. The gas generator 31 may be, for example, a micro gas generator or the like, but may be any device as long as it has a relatively high output, generates a large amount of gas, and operates for a long time. The gas generating agent is an agent (gunpowder or propellant) that is ignited by hot particles generated by the operation of the igniter and combusts to generate gas. Also, the type and quantity of explosives and the form of the gas generator can be appropriately selected.

In general, gas generators can be broadly classified into non-explosive type and explosive type. The mainstream of non-explosive type is to connect a sharp member such as a needle and a compressed spring to a gas cylinder filled with gas such as carbon dioxide or nitrogen, and use the spring force to blow off the sharp member and seal the cylinder. Compressed gas is released by colliding with the sealing plate. At this time, a drive source such as a servomotor is usually used to release the compressive force of the spring. Next, in the case of the gunpowder type, the igniter alone may be used, or the igniter and the gas generating agent may be provided. Alternatively, a hybrid type or stored type gas generator may be used in which the sealing plate of a small gas cylinder is opened by the power of gunpowder and the internal gas is discharged to the outside. In this case, the pressurized gas in the gas cylinder is selected from at least one or more nonflammable gases such as argon, helium, nitrogen, and carbon dioxide. In addition, the gas generator may be provided with a pyrotechnic heating element to ensure expansion of the pressurized gas when it is released. Additionally, the gas generator may be provided with filters and/or orifices to regulate gas flow as required.

As the gas generating agent, it is preferable to use a non-azide gas generating agent, and generally the gas generating agent is formed as a compact containing a fuel, an oxidant and an additive. As the fuel, for example, a triazole derivative, a tetrazole derivative, a guanidine derivative, an azodicarbonamide derivative, a hydrazine derivative, or a combination thereof is used. Specifically, nitroguanidine, guanidine nitrate, cyanoguanidine, 5-aminotetrazole and the like are preferably used. The oxidizing agent may be selected from basic nitrates such as basic copper nitrate, perchlorates such as ammonium perchlorate and potassium perchlorate, alkali metals, alkaline earth metals, transition metals and ammonia. Nitrates and the like containing cations containing As nitrates, for example, sodium nitrate, potassium nitrate and the like are preferably used. Additives include binders, slag forming agents, and combustion modifiers. As the binder, organic binders such as metal salts of carboxymethyl cellulose and stearates, or inorganic binders such as synthetic hydroxytalcite and acid clay can be preferably used. As the slag forming agent, silicon nitride, silica, acid clay, etc. can be suitably used. Metal oxides, ferrosilicon, activated carbon, graphite and the like can be suitably used as combustion modifiers. In addition, a single-base gunpowder, a double-base gunpowder, or a triple-base gunpowder containing nitrocellulose as a main component may be used.

In addition, the shape of the molded body of the gas generating agent includes various shapes such as granular shapes such as granules, pellets, and cylindrical shapes, and disk shapes. In addition, in the case of a columnar shape, a perforated shaped body having through holes inside the shaped body (for example, a single-hole cylindrical shape or a multi-hole cylindrical shape) is also used. In addition to the shape of the gas generating agent, it is preferable to appropriately select the size and filling amount of the molded body in consideration of the linear burning velocity, pressure index, etc. of the gas generating agent.

The sensor unit 40 shown in FIG. 5 detects a vehicle collision and outputs a vehicle collision detection signal, which is the detected information, to the control unit 41 . Examples of the sensor unit 40 include an acceleration sensor and a vibration sensor.

The control unit 41 transmits command signals as necessary to control the winding device 12 . A start signal is output to the gas generator 31 of the . The control unit 41 also receives a vehicle collision detection signal from the sensor unit 40 in real time, and determines whether or not to operate the lock mechanism 25 according to the received vehicle collision detection signal.

When the vehicle safety device 100 configured as described above is applied, the passenger P1 is not restrained by the vehicle safety device 100 as much as the seat belt under normal conditions. can spend On the other hand, when the vehicle encounters an accident such as a collision, the vehicle safety device 100 operates. That is, the control unit 41 operates or stops the servomotor 22 of the winding device 12 to control the pulling amount of the connecting member 11 and to operate the gas generator 31 .

At this time, in the gas generator 31 , a large amount of gas is instantaneously generated by combustion of the gas generating agent, the gas pressure breaks the cup body, and the gas accompanied by pressure is supplied to the space 37 in the tubular member 36 . will be The space 37 whose pressure is increased by this gas instantly moves the moving member 34 in the direction of the white arrow in FIG. 33 is rotated, the take-up shaft 32 and the reel shaft 23 are also rotated. Finally, as shown in FIG. 4(b), the moving member 34 moves to the maximum limit position and this state is maintained.

By operating the lock mechanism 25 in this manner, the rotation of the reel 24 can be stopped and locked. Therefore, when the vehicle encounters an accident such as a collision, the vehicle safety device 100 winds up the connecting member 11 by a predetermined length as necessary so that the passenger P1 is not released outside the vehicle. can. Further, for example, if the servo motor 22 is adjusted so that the connecting member 11 can be extended only to a length that can avoid a collision with relatively hard equipment in the vehicle, the vehicle may collide. Even in the event of an accident, collision between the passenger P1 and the equipment can be avoided.

<Second embodiment>
Next, a vehicle safety device 200 according to a second embodiment of the invention will be described with reference to FIGS. 6 to 8. FIG. In the present embodiment, unless otherwise specified, the reference numerals having the same last two digits are the same, so the description may be omitted.

The vehicle safety device 200 differs from the vehicle safety device 100 in that instead of the servomotor 22, a spring portion 122 using a spiral spring is provided. Here, although not shown, one end at the center of the spiral spring is fixed to the reel shaft 123 , and the other end at the outer edge of the spiral spring is fixed inside the case 122 a of the spring portion 122 . A spiral spring is a mechanical element in which highly elastic material is wound in a spiral shape. is called.

As a result, a load can be applied to the reel 124 when the connecting member 111 is let out, and a predetermined tension is applied to the connecting member 111 between the ring portion 104 of the equipment 110 worn by the passenger P2 and the winding device 112. It can be held (see FIG. 6).

According to the vehicle safety device 200 configured as described above, the same effects as those of the first embodiment can be obtained. In addition, since the connecting member 111 can be maintained with a predetermined tension between the ring portion 104 of the equipment 110 worn by the passenger P2 and the winding device 112, the connecting member 111 is free from slack. In addition, the initial action time of the vehicle safety device 200 can be shortened compared to the vehicle safety device 100 when an accident such as a vehicle collision occurs.

Although the embodiments of the present invention have been described above, the specific examples are merely illustrated, and the present invention is not particularly limited. Further, the actions and effects described in the embodiments of the invention are merely enumerations of the most suitable actions and effects resulting from the present invention, and the actions and effects of the present invention are described in the embodiments of the invention. are not limited to those listed.

For example, in the above-described first embodiment, the controller 41 may control the operation of the servo motor 22 of the winding device 12 so that the connecting member 11 maintains a predetermined tension as in the above-described second embodiment. good.

Also, as shown in FIGS. 9A and 9B, a harness-type brace 210 may be used instead of the braces 10 and 110 in the first and second embodiments. As a result, the effects of the first and second embodiments can be influenced for the entire body of the passenger P3. Here, FIG. 9(a) is a front view of the passenger to whom the harness-type equipment 210 is attached, and FIG. 9(b) is a rear view of the passenger to which the harness-type equipment 210 is attached. It is a diagram.

Further, in the first embodiment, the lock mechanism 25 shown in FIGS. 4(a) and 4(b) is used, but instead of this, the lock mechanism 50 shown in FIGS. may be used. The lock mechanism 50 will be described below.

The lock mechanism 50 includes a ring gear 51 and a power transmission section 60 (power transmission means) that transmits power to the ring gear 51 in an emergency (for example, when the vehicle detects or predicts a collision). . The power transmission unit 60 includes a spherical member 61 configured to be engageable with the external teeth 51a of the ring gear 51, a pipe 62 accommodating the spherical member 61, and a gas generator 63 ( (similar to the gas generator 31 described above), a piston 64 that receives the gas generated from the gas generator 63 and presses the spherical member 61 (power transmission member), and a passage 71 of the spherical member 61 are formed inside. a housing 70 in which the

The housing 70 is provided on the side of the other end of a support (not shown) similar to the support 21 described above. The pipe 62 is curved so as not to come into contact with the support base and a connecting member (not shown) similar to the connecting member 11 . Like the winding shaft 32, the winding shaft 80 is rotatable following a reel shaft (not shown), and is concentrically connected to a pinion gear 81 (rotating member). External teeth 81 a formed on the outer periphery of the pinion gear 81 are configured to be able to engage with internal teeth 51 b formed on the inner periphery of the ring gear 51 .

As shown in FIG. 10(a), in the initial state (before operation), a clearance is provided between the external teeth 81a of the pinion gear 81 and the internal teeth 51b of the ring gear 51. The shaft 80 and pinion gear 81 are rotatable without interfering with the ring gear 51 . That is, in the initial state, the locking mechanism 50 is not operated, the reel shaft is rotatable, and the connecting member can be delivered.

Further, as shown in FIG. 10(a), the outer teeth 51a of the ring gear 51 are capable of engaging two of each of the valleys that can engage only the first spherical member 61 and the second and subsequent spherical members 61. and a valley. Further, the ring gear 51 is formed in an annular shape, and has internal teeth 51b that are engageable with the external teeth 81a of the pinion gear 81 on the inner periphery thereof.

Further, as shown in FIG. 10(a), a plurality of spherical members 61 are filled in the pipe 62, and are supported by the external teeth 51a of the ring gear 51 so as not to move in the initial state. A passage 71 is formed inside the housing 70 so that the spherical member 61 can move along the outer circumference of the ring gear 51 along the side wall.

A piston 64 is arranged at the rear end of the spherical member 61 accommodated in the pipe 62 (see FIG. 10(b)). A gas generator 63 is arranged at the end of the pipe 62 .

Immediately before landing or just before a collision of an aircraft equipped with the lock mechanism 50 having such a configuration, the operation of the sensor section (the same as the sensor section 40 of the above embodiment) and the control section (the control section 41 of the above embodiment) A high-pressure gas is jetted into the pipe 62 from the gas generator 63 which is operated by the control of the . This high-pressure gas causes the piston 64 to slide in the pipe 62 while being in close contact with the inner surface of the pipe 62 to prevent leakage of the high-pressure gas. By sliding the piston 64 , the plurality of spherical members 61 arranged in a row are pressed and moved within the pipe 62 .

The first spherical member 61 pushed out from the pipe 62 presses the ring gear 51 while engaging with the outer teeth 51 a of the ring gear 51 , and the ring gear 51 moves toward the pinion gear 81 . As a result, the inner teeth 51b of the ring gear 51 and the outer teeth of the pinion gear 81 are engaged with each other, and the rotation of the ring gear 51 enables the pinion gear 81 to rotate, thereby starting to rotate the winding shaft 80 and the reel shaft. .

Subsequently, as shown in FIG. 10(b), the spherical member 61 is sequentially discharged from the pipe 62 by the high-pressure gas supplied from the gas generator 63, and after rotating the ring gear 51, the ring gear 51 is rotated. It disengages and moves along path 71 . When the spherical member 61 reaches the terminal end of the passage 71, it stops moving.

The spherical member 61 that has reached the terminal end of the passage 71 is pressed by the high-pressure gas, and as shown in FIG. and stop moving.

The lock mechanism 50 having such a configuration can achieve the same effect as the lock mechanism 25 of the above embodiment. Although the spherical member 61 is an example of the power transmission member, it is not limited to this, and any member may be used as long as it can transmit power to the ring gear. For example, a flexible elongated member made of resin or rubber (having the same diameter as the spherical member 61) having a portion that matches the shape and position of each external tooth of the ring gear may be used as a plurality of may be used instead of the spherical member 61 of . As a result, when the lock mechanism operates, the ring gear can be rotated and moved toward the pinion gear, so that the same effects as when the plurality of spherical members 61 in the above embodiment are used can be achieved. can.

Further, in the second embodiment, the winding device 112 automatically winds the connecting member, but instead of this, a conventional automatic winding device may be used. For example, although not shown, this automatic winding device is housed in a housing and one side of the housing. When a connecting member such as a wire is pulled, the connecting member wound around a retractable rotating plate is paid out and the connecting member is pulled. an automatic winding module that automatically locks to maintain the current length when the winding is stopped and automatically winds the connecting member when the locking is released; a locking plate rotated together with the automatic winding module; a locking module interlocked with the locking plate to allow rotation of the automatic winding module in one direction, lock rotation in the other direction, and allow rotation in the other direction when the release button is pushed down. be done.

The automatic winding module has a retractable rotating plate (not shown) around which the connecting member is wound, and an elastic member (not shown) that applies a rotational force to the retractable rotating plate in the direction in which the connecting member is wound. including. The locking plate, which is arranged on the same axis as the retractable rotating plate and rotates together, is formed with a plurality of braking teeth that allow rotation in one direction and restrict rotation in the other direction. Rotation in one direction is allowed by pushing out the stopper of the locking module along the inclined surface of , but when rotating in the other direction, the locking step of the braking sawtooth catches the stopper of the locking module. This prevents rotation in other directions.

In the automatic winding device with such a structure, when the user pulls the connecting member, the stopper of the locking module is pushed out along the inclined surface of the braking sawtooth, and the retractable rotary plate rotates in one direction, thereby winding the device. When the user releases the connecting member, the locking plate rotates in the opposite direction due to the restoring force of the retractable rotating plate, and the locking stepped portion of the braking sawtooth catches the stopper of the locking module. , the connecting member maintains its current length.

When the user presses the release button of the locking module, the locking module is actuated to push the stopper caught on the locking step backward to release the locking, and the retractable rotating plate moves in the other direction due to the restoring force. The connecting member is automatically wound up by being rotated to. Therefore, the connecting member is always wound up by the automatic winding device with enough force to be accommodated in the housing. Therefore, when the occupant removes the brace, the connecting member is automatically wound up and stored in the housing.
