Description

  The present invention relates to a safety device used for a passenger who rides a vehicle.

  FIG. 10 is a diagram schematically showing a shoulder presser arm 110 according to a conventional technique. As a vehicle safety device according to the prior art, there is a passenger holding device including a shoulder pressing arm 110 that holds and holds a shoulder of a vehicle occupant, and a lock means that prevents the shoulder pressing arm from moving upward. known. In this passenger holding device, the shoulder pressing arm 110 is provided with a sponge 111 as a cushioning material that comes into contact with the shoulder of the occupant from the upper end to the tip (see, for example, Patent Document 1).

JP-A-6-292768

In the safety device according to the prior art, since the cushioning material that contacts the occupant is made of sponge, the pressing force acting on the occupant's body from the shoulder presser arm 110 differs depending on the portion of the contact surface of the cushioning material. There is a problem that there is little feeling.
An object of the present invention is to provide a vehicle safety device with improved fit.

  According to the present invention (1), the safety device includes the movement restricting portion and the bag-like member. The movement restriction unit is installed in the vehicle and restricts the movement range of the passenger who has boarded the vehicle seat. The bag-like member is disposed between the movement restricting portion and the passenger and is formed from a flexible material. The interior space of the bag-like member is filled with fluid.

  Furthermore, according to this invention (2), the area of the passenger side surface which faces a passenger among the outer surfaces of a bag-shaped member is the outer surface of the site | part by which the bag-shaped member of a movement restriction part is arrange | positioned, Consists of more than the area of the facing surface facing the passenger.

  Furthermore, according to this invention (3), a bag-shaped member is formed with the material which has rubber elasticity.

Furthermore, according to this invention (4), a bag-shaped member is connected with a movement restriction | limiting part.
Furthermore, according to the present invention (5), a plurality of bag-like members are provided corresponding to a predetermined number of passengers. Further, the bag-like members are connected by a communication pipe that communicates the internal spaces with each other.

  Furthermore, according to this invention (6), the valve which can interrupt | block communication between the interior space and interior space by a pipe line is arrange | positioned in the middle position of the pipe line formed by a communicating pipe.

Further in accordance with the invention (7), the fluid is at a predetermined temperature.
Furthermore, according to the present invention (8), the safety device further includes a temperature adjusting unit that changes the temperature of the fluid.

  Furthermore, according to this invention (9), a bag-shaped member is further comprised including the protrusion part which protrudes when the pressure of the fluid rises.

  Furthermore, according to the present invention (10), the safety device further includes a pressure detector that detects the pressure of the fluid.

  Furthermore, according to the present invention (11), the safety device further includes a fluid supply part that supplies a fluid to the bag-like member, and the fluid supply part has a pressure that is detected by the pressure detection part at a predetermined pressure. When reached, supply fluid.

  According to the present invention, since the fluid is filled in the internal space of the bag-shaped member, the pressing force applied by the passenger to the movement restricting portion can be dispersed by the fluid filled in the internal space of the bag-shaped member. . As a result, the surface portion of the bag-like member that applies the pressing force to the passenger can apply the same pressure to the passenger's body in any part. Therefore, it is possible to obtain a restrained state regardless of the difference in the body shape of the occupant, to improve the fit of the occupant to the safety device, and to increase the sense of security of the occupant. Since the bag-shaped member can be freely deformed into a shape corresponding to the shape of the contact area of the occupant by the movement of the fluid inside, the pressing force acting on the bag-shaped member from the occupant regardless of the body shape of the occupant Depending on the size and the direction of action, the bag-like member is deformed within the set pressure range, and receives the reaction force against the pressing force in a distributed state from the region in contact with the body. As a result, the occupant receives a reaction force in which the pressing force is always distributed over a wide area, regardless of the body shape and posture.

  Further, according to the present invention, when the bag-like member is not provided, the area on which the pressing force acts on the occupant can be made larger than the surface area of the movement restricting portion that applies the pressing force to the occupant. In addition, since the surface portion of the bag-like member that applies the pressing force to the passenger can apply the same pressure to the passenger in any part, the area where the pressing force acts on the passenger is small. Compared to the case, the pressure applied to the passenger can be reduced. Thereby, compared with the case where a bag-shaped member is not provided, a passenger | crew's sense of security with respect to a vehicle can be increased.

  According to the present invention, since the bag-like member has rubber elasticity, it can be extended when the fluid pressure in the internal space is increased by being pressed by the passenger and the movement restricting portion. Thereby, the surface area of the bag-like member can be enlarged. Therefore, compared with the case where the surface area of a bag-like member does not change, the area which gives a pressing force to a passenger can be expanded, and the pressure given to a passenger can be made small.

  In addition, the bag-like member can convert an increase in energy caused by pressure increase due to the pressure from the passenger into extension energy, and can reduce the energy accompanying the reaction to the passenger. Therefore, it is possible to reduce the reaction against sudden application of pressing force from the passenger, and increase the passenger's sense of security.

  Moreover, according to this invention, since a bag-shaped member is connected with a movement restriction | limiting part, it can suppress that a bag-like member displaces with respect to a movement restriction | limiting part. Therefore, the bag-like member can be reliably positioned between the passenger's body and the movement restricting portion.

  Moreover, according to this invention, a communicating pipe | tube connects each internal space of a some bag-shaped member. As a result, the fluid in the bag-like member moves while satisfying the Pascal principle. Therefore, when the plurality of bag-like members are brought into contact with a plurality of passengers, the bag-like member is applied to the passengers. The pressure can be equal on any surface of the bag-like member that contacts the occupant. Therefore, when a plurality of bag-like members are brought into contact with a plurality of passengers, it is possible to prevent the fit feeling of each passenger's bag-like member from being different due to differences in the physique of each passenger. .

  The pressing force applied to the fluid in the bag-like member from the passenger and the movement restriction unit can be the same in any bag-like member. A bag-like member with a relatively small pressing force applied to the fluid from the passenger can expand more than a bag-like member with a relatively large pressing force applied to the fluid from the passenger. Therefore, it can suppress that the space | interval of a bag-shaped member and a passenger changes with the difference of a passenger's physique.

  Further, according to the present invention, by closing the valve, it is possible to prevent the fluid from moving between the internal space and the internal space of the bag-like member adjacent to each other via the valve with respect to communication by the pipe line. Become. Thereby, it is possible to prevent the fluid pressure in the internal space of the bag-like member from affecting the fluid pressure in the internal space of the adjacent bag-like member via the valve with respect to communication through the pipe line.

  In addition, when a bag-shaped member corresponding to a seat on which the passenger is seated and a bag-shaped member corresponding to a seat on which the passenger is not seated are adjacent to each other via a valve with respect to the pipeline, the bag corresponding to the seat on which the passenger is not seated It can prevent that a shape member influences with respect to the movement of the fluid in the bag-shaped member corresponding to the seat which a passenger seats.

  According to the invention, the fluid is set to a predetermined temperature. Accordingly, the passenger can feel a predetermined temperature via the bag-like member, and the comfort of the passenger with respect to the vehicle can be improved.

  Moreover, according to this invention, the temperature adjustment part can change the temperature of the fluid in a bag-shaped member. This allows the fluid temperature to be higher than the ambient temperature if the ambient temperature is a temperature that the passenger feels cold, and if the ambient temperature is a temperature that the passenger feels hot. The fluid temperature can be lower than the ambient temperature. Therefore, the comfort for the rider's vehicle can be improved.

  According to the invention, the protruding portion protrudes due to an increase in fluid pressure. Thereby, the protrusion of the protrusion and the shape of the protruded protrusion can be used as effects for the passenger. Further, the bag-like member has a protruding portion when the pressing force from the passenger and the pressing force from the movement restricting portion are applied to the bag-like member and the fluid pressure in the internal space of the bag-like member increases. It can be projected to the passenger side. Thereby, the bag-like member can prevent a sudden increase in the fluid pressure in the bag-like member when a pressing force against the bag-like member is abruptly applied from the occupant's body. Therefore, the reaction imparted to the passenger's body from the bag-like member can be reduced, and the passenger's comfort can be improved as compared with the case where no protrusion is formed on the bag-like member.

  According to the invention, the safety device further includes a pressure detection unit that detects the pressure of the fluid in the bag-like member. Thereby, the fluid pressure in the internal space of the bag-like member can be controlled. In addition, fluid leakage can be detected.

  According to the invention, the safety device further includes a fluid supply unit that supplies fluid to the bag-like member. Thus, the safety device can supply fluid to the internal space of the bag-like member when the fluid pressure in the internal space of the bag-like member reaches a predetermined pressure. Therefore, the bag-shaped member reliably applies fluid between the passenger and the movement restricting portion even when a sudden pressing force is applied from the body of the passenger and the bag-shaped member extends greatly. It is possible to prevent the passenger and the movement restricting portion from directly applying a pressing force to each other. In addition, since the pressing force from the passenger and the pressing force from the movement restriction unit can be reliably dispersed by the fluid in the bag-like member, the passenger and the movement limitation unit directly apply the pressing force to each other. Compared to the case, the mutual pressing force between the passenger and the movement restriction unit can be reduced.

  Hereinafter, a plurality of embodiments for carrying out the present invention will be described with reference to the drawings. In the following description, parts corresponding to matters already described in the forms preceding each form may be denoted by the same reference numerals, and overlapping descriptions may be omitted.

FIG. 3 is a side view of the vehicle 100 in the first embodiment. FIG. 4 is a front view of the vehicle 100 in the first embodiment.

  In the present embodiment, the vehicle 100 is a play vehicle installed in an amusement park or the like. The vehicle 100 includes a base 2 constituting a part of the vehicle body and a seat 3 on which a passenger 7 sits, and the vehicle 100 is provided with a safety device 1. A seat 3 is provided on one surface of the base 2 of the vehicle 100. Hereinafter, this one surface is referred to as “floor surface 4”. The floor surface 4 is formed in a single plane. The vehicle 100 is stopped at a predetermined position, and the passenger 7 is boarded and moved out in the stopped state. The state stopped at this position is referred to as a “natural state”. In the natural state, the floor surface 4 is disposed substantially horizontally and facing upward.

  The seat 3 is generally formed in an L shape when viewed from the side, and the seat portion 5 that is a portion where the passenger 7 sits with the buttocks in contact with the backrest portion 6 that is the portion where the back of the passenger 7 contacts. And. The seat part 5 and the backrest part 6 are both formed in a substantially flat plate shape. In this embodiment, the seats 3 are provided in a plurality of rows in the front-rear direction, and in each row, a plurality of seats 3 are formed in the left-right direction.

  In the following description, the front-rear direction of the occupant 7 sitting on the seat 3 out of the straight directions parallel to the floor surface 4 is simply referred to as “front-rear direction” X. The direction toward the seat portion 5 is referred to as “front” X1, and the reverse direction of the front X1 is referred to as “rear” X2. Further, a direction parallel to the floor surface 4 and perpendicular to the front-rear direction X is referred to as “left-right direction” Y. Of the left-right direction Y, the right-hand direction as viewed from the front X1 is referred to as “right” Y1, and is the reverse of right-side Y1. The direction is referred to as “left” Y2. A direction perpendicular to the floor surface 4 is referred to as an “up and down direction” Z. Among the up and down directions Z, a direction in which the seat 3 is provided when viewed from the floor surface 4 is referred to as an “upward” Z1, and a reverse direction of the upper Z1 is referred to as “downward”. Is referred to as Z2.

  The safety device 1 includes a movement restriction unit 10, a buffer member 13, and a bag-like member 30. The safety device 1 may have a state in which movement of the passenger 7 is restricted and a state in which the restriction is released. Hereinafter, a state where the safety device 1 restricts movement of the passenger 7 is referred to as a “restricted state”, and a state where the restriction is released is referred to as a “released state”.

  The movement restriction unit 10 is installed in the vehicle 100 and restricts the movement range of the passenger 7 who has boarded the seat 3 of the vehicle 100. The movement restriction unit 10 is disposed near the abdomen of the passenger 7 in the restricted state, restricts the movement of the passenger 7, and releases the restriction by moving away from the body of the passenger 7 in the released state.

  The movement restriction unit 10 includes an angular displacement control unit 11 and a support member 12. The support member 12 is a member that supports the buffer member 13. The support member 12 is made of, for example, a metal cylindrical member such as a metal pipe, and is formed in a substantially U-shape in the present embodiment. The support member 12 includes two standing leg portions 12 a located at both ends in the left-right direction Y and a support portion 12 b that supports the buffer member 13. The standing leg portion 12a is a longitudinal member that intersects the floor surface 4, and the end portion of the standing leg portion 12a closest to the floor surface 4 is mechanical with respect to the angular displacement control unit 11 described in detail later. Connected to. The support portion 12 b is disposed so as to extend in the left-right direction Y substantially parallel to the floor surface 4. In the present embodiment, “substantially parallel” includes “parallel”. Both ends in the left-right direction Y of the support portion 12b are connected to the end portion of the standing leg portion 12a that is farthest from the floor surface 4.

  The support member 12 is provided so as to be angularly displaceable around a common axis that passes through the two ends of the standing leg portion 12 a connected to the angular displacement control unit 11. The two end portions of the standing leg portion 12a in the vicinity of the floor surface 4 are arranged in the vicinity of the position of the foot of the occupant 7 in the front-rear direction X. The length of the leg portion 12a is set to a length equal to the distance from the abdomen of the passenger 7 to the feet of the passenger 7 in a state where the passenger 7 has boarded. The support member 12 is switched between a restricted state and a released state by angular displacement about the common axis. In the restricted state, the support portion 12b is disposed in the vicinity of the abdomen of the occupant 7, and in the released state, the support portion 12b is disposed at a position far from the abdomen of the occupant 7. Between the two ends of the standing leg portion 12a in the vicinity of the floor surface 4 and the seat 3, the floor surface 4 has an area of a size that allows the passenger 7 to step on the floor surface 4 when boarding and leaving. Secured.

  The support member 12 further includes a plurality of protruding pieces 20 that protrude from the support portion 12 b, and the buffer member 13 is attached to the support member 12. The buffer member 13 surrounds at least a portion of the support portion 12b where the protruding piece 20 is formed. The protruding piece 20 is formed as a member protruding from the support portion 12b to either the upper Z1 or the lower Z2 in the restricted state. In the present embodiment, the protruding piece 20 protrudes in both the upper Z1 and the lower Z2. In the restricted state, each protruding piece 20 is formed as a flat plate member whose thickness direction is the front-rear direction X. The thickness of the protruding piece 20 is set to a dimension smaller than the diameter of the cross section perpendicular to the left-right direction Y of the support portion 12b.

  Each protruding piece 20 is provided corresponding to the number of seats 3, and the length of each protruding piece 20 in the left-right direction Y is set to be smaller than the dimension of each seat portion 5 in the left-right direction Y. Further, the length in the left-right direction Y of each protruding piece 20 is set to be smaller than the dimension in the left-right direction Y of each buffer member 13 described in detail later. Thus, when the plurality of buffer members 13 are provided corresponding to each passenger 7 seated in each seat 3, each protruding piece 20 is positioned inside each buffer member 13. Therefore, the buffer member 13 prevents the passenger 7 from coming into direct contact with the protruding piece 20. The protruding piece 20 is formed so as to protrude in the radial direction with respect to the axis of the support portion 12b, and the size in the radial direction may be a size that prevents the buffer member 13 from rotating around the axis. If the dimension of the projecting piece 20 in the radial direction is too long, it is necessary to set the buffer member 13 for enclosing the projecting piece 20 excessively large, and if it is too short, the buffer member 13 can be prevented from rotating. Can not.

  The protruding piece 20 is formed as a flat plate-like member, and is formed to protrude from the support portion 12b to either the upper Z1 or the lower Z2 when the support member 12 is in the restricted state. Accordingly, the protruding piece 20 can be positioned with the surface perpendicular to the thickness direction thereof in the front-rear direction X in the restricted state. Therefore, the protruding piece 20 can support the bag-like member 30 on the surface perpendicular to the thickness direction. Thereby, it is possible to prevent the protruding piece 20 from damaging the bag-like member 30. If the bag-like member 30 is deformed and the body of the occupant 7 and the projecting piece 20 give a pressing force to each other without fluid, the projecting piece 20 causes the body of the occupant 7 to touch the surface. Can be supported. Therefore, the pressure applied to the body of the occupant 7 can be reduced as compared with, for example, the case where the protruding piece 20 protrudes in the front-rear direction X in the restricted state.

  The angular displacement control unit 11 controls the angular displacement around the common axis of the standing leg 12a. This also controls the angular displacement of the support member 12 and switches the movement restricting portion 10 between the restricted state and the released state. When the passenger 7 gets on the vehicle 100 and sits on the seat 3, the angular displacement control unit 11 places the movement restriction unit 10 in a restricted state and restricts the movement restriction unit 10 from being released. The angular displacement control unit 11 has a lock, and the lock takes two modes, an on state and an off state. In the ON state, the lock allows the angular displacement of the support member 12 in the direction in which the support portion 12b moves backward X2, and prevents the angular displacement of the support member 12 in the direction in which the support portion 12b moves forward X1. The lock allows the angular displacement of the support member 12 when the support portion 12b moves in any direction in the front-rear direction X in the off state.

  After the rider 7 gets on the vehicle 100, the administrator of the vehicle 100 turns on the lock, angularly displaces the support member 12, and brings the support part 12b close to the body of the rider 7. The angular displacement amount of the support member 12, that is, the displacement amount in the front-rear direction X of the support portion 12 b is adjusted according to the physique of the passenger 7. When the passenger 7 leaves the vehicle 100, the vehicle 100 is stopped in a natural state. Thereafter, the administrator turns off the lock of the angular displacement control unit 11, angularly displaces the support member 12 in the direction in which the support unit 12 b is displaced forward X 1, and sets the movement restriction unit 10 in the released state. In the released state, the support portion 12b and the backrest portion 6 are separated from each other, and movement of the passenger 7 in the left-right direction Y is allowed. The passenger 7 moves away from the vehicle 100 by moving between the seat 3 and the support member 12 to at least one of the left side and the right side of the vehicle 100 in the released state.

  The buffer member 13 transmits the applied pressure. The buffer member 13 is made of, for example, a rubber elastic member such as sponge or urethane rubber, and is formed of sponge in the present embodiment. In the present embodiment, the buffer member 13 is formed in an approximately elliptical column shape, and has at least the same length as the width direction of the seat 3. On the outer surface of the buffer member 13, a recess 22 that is recessed inward for providing the bag-like member 30 is formed. The buffer member 13 is attached and includes the protruding piece 20 and the support portion 12 b so that the recess 22 is disposed on the passenger 7 side, and is fixed to the support member 12. The buffer member 13 is provided corresponding to a predetermined number of passengers of the vehicle 100. In the present embodiment, since the vehicle 100 is provided with three seats 3 in each row, three buffer members 13 are provided in each row.

  The bag-shaped member 30 is disposed between the movement restricting portion 10 and the occupant 7 and is formed from a flexible material. The bag-shaped member 30 is formed of a material having rubber elasticity. The bag-shaped member 30 is supported by the movement restriction unit 10. The bag-like member 30 disperses the pressing force applied to the movement restriction unit 10 by the passenger 7 when the vehicle 100 is operating. The bag-shaped member 30 is formed of a flexible member such as polyethylene, polypropylene, or polyvinyl, or a rubber elastic member such as isoprene rubber or butadiene rubber. Examples of the material having rubber elasticity include diene rubber and olefin rubber. In the present embodiment, the bag-like member 30 is formed using butadiene rubber. If the bag-like member 30 is made of a material having rubber elasticity, the bag-like member extends when the bag-like member 30 is pressed by the passenger 7 and the movement restricting portion 10 and the fluid pressure in the internal space 70 increases. be able to. Thereby, the surface area of the bag-shaped member 30 can be enlarged. Therefore, compared with the case where the surface area of the bag-shaped member 30 does not change, the area which gives a pressing force to the passenger 7 can be expanded, and the pressure applied to the passenger 7 can be made small.

  The internal space 70 of the bag-like member 30 is filled with fluid. The fluid may be a liquid or a gas, and may be a compressive fluid or an incompressible fluid. In this embodiment, air is filled.

  FIG. 5 is a cross-sectional view showing the bag-shaped member 30, the support member 12, and the buffer member 13 in the first embodiment of the present invention. In FIG. 5, among the outer surfaces of the bag-shaped member 30, the passenger-side surface among the passenger-side surface 80 facing the passenger and the outer surface of the portion where the bag-shaped member 30 of the movement restriction unit 10 is disposed. An opposing surface 81 facing 80 is shown. The passenger-side surface 80 of the bag-shaped member 30 is a surface facing the direction away from the support portion 12b among the outer surfaces of the bag-shaped member 30, and in this embodiment, approximately half of the outer surface of the bag-shaped member 30. It has a certain area.

  The facing surface 81 of the movement restricting portion 10 is a surface on the side facing the bag-like member 30 among the outer surfaces of the support portion 12b and the protruding piece 20. Of the outer surface of the bag-shaped member 30, the area of the passenger side surface 80 to which the pressing force from the passenger 7 acts is configured to be equal to or larger than the area of the opposing surface 81 of the movement restriction unit 10. If the bag-shaped member 30 is not disposed and the body of the occupant 7 applies a pressing force to the support portion 12b and the protruding piece 20 directly or via the buffer member 13, the support portion 12b and the protruding portion are counteracted. The area where the piece 20 applies force to the body is approximately equal to the area of the opposing surface 81.

  On the other hand, in the present embodiment, the pressing force applied to the body of the passenger 7 from the support portion 12b and the protruding piece 20 is applied to the entire passenger-side surface 80. Since the pressure applied to the body of the passenger 7 from each part of the passenger side surface 80 is equal in each part, and the area of the passenger side surface 80 is larger than the area of the opposing surface 81, the bag-like member The pressure applied to the body of the occupant 7 can be reduced as compared with the case where 30 is not provided and the case where the area of the passenger side surface 80 is set to be equal to or less than the area of the opposing surface 81.

  In the present embodiment, the bag-shaped member 30 is attached to the recess 22 formed on the outer surface of the buffer member 13. At this time, the area of the occupant side surface 80 on which the pressing force from the occupant 7 acts out of the outer surface of the bag-shaped member 30 is the above-described outer surface of the support portion 12b that constitutes the movement restriction unit 10. It is formed larger than the area of a part of the opposing surface 81 facing the passenger side surface 80. Therefore, when the bag-like member 30 is not provided, the area on which the pressing force acts on the passenger 7 can be made larger than the surface area on which the movement restricting unit 10 applies the pressing force to the passenger 7.

  In addition, the bag-like member 30 can convert the increase in energy caused by pressure increase from the passenger 7 by pressing into the extension energy, and can reduce the energy accompanying the reaction to the passenger 7. . Therefore, the reaction to the sudden application of pressing force from the passenger 7 can be reduced, and the sense of security of the passenger 7 can be increased.

  Further, as described above, since the buffer member 13 is attached in a state where angular displacement about the axis of the support member 12 is prevented, when the bag-like member 30 is attached to the recess 22, the bag-like member 30. However, displacement with respect to the movement restricting portion 10 can be suppressed, and the bag-like member 30 can be reliably positioned between the passenger 7 and the movement restricting portion 10.

  FIG. 6 is a diagram showing a configuration of the safety device 1 according to the first embodiment of the present invention. The vehicle 100 has a plurality of seats 3 for a plurality of passengers 7, and a plurality of bag-like members 30 are provided corresponding to the number of seats 3.

  The safety device 1 further includes a communication pipe 31 that communicates the internal spaces 70 of the bag-like members 30 with each other. A valve capable of blocking communication between the internal space 70 and the internal space 70 by the pipe is disposed at a midway position of the pipe formed by the communication pipe 31.

  The safety device 1 further includes a pressure detection unit 35 that detects the pressure of the fluid and a fluid supply unit that supplies the fluid to the bag-shaped member 30. When the pressure of the fluid detected by the pressure detection unit 35 reaches a predetermined pressure, the fluid supply unit supplies the fluid to the internal space 70 of the bag-like member 30 via the pipe line.

  The description will be made with reference to FIGS. 1, 2 and 4 again. As shown in FIG. 4, the vehicle 100 is provided with three seats 3 arranged in the left-right direction. The movement restricting portion 10 is provided with three buffer members 13 corresponding to the respective seats 3, and the buffer members 13 are provided with bag-like members 30 a, 30 b, and 30 c, respectively. In this embodiment, the valve which can interrupt | block communication between the internal space 70 and the internal space 70 by a pipe line is implement | achieved by cock 34a, 34b, 34c, 34d. However, the valve is not limited to the cock, and may be, for example, an on-off valve, an adjustment valve that can adjust the squeeze, or the like. A communication pipe 31 provided along the support member 12 is connected to the bag-shaped members 30 a, 30 b, and 30 c, and the internal spaces 70 of the bag-shaped members 30 a, 30 b, and 30 c are connected by the communication pipe 31, respectively. Therefore, the fluid filled in the internal space 70 of each bag-like member 30a, 30b, 30c can move through the communication pipe 31 in the internal space 70 of each bag-like member 30a, 30b, 30c.

  The communication pipe 31 is connected to the main pipe line 32 and the diffusion valve side pipe line 33 provided with the diffusion valve 33a. The upstream side of the bag-like member 30a, between the connecting pipes connecting the bag-like member 30a and the bag-like member 30b, between the connecting pipes connecting the bag-like member 30b and the bag-like member 30c, and of the bag-like member 30c On the downstream side, cocks 34a, 34b, 34c, and 34d are provided. A pressure detection unit 35 that detects the pressure of the fluid in the communication pipe 31 is provided on the upstream side of the cock 34d. The main pipeline 32 is a pipeline connected to the pressure accumulator 40. The main pipe line 32 is branched into a pressure accumulator side pipe line 41 connected to the pressure accumulator 40 and an on-off valve side pipe line 38 connected to the on-off valve 37a at a branch point upstream of the check valve 36. .

  A connecting device 39a for connecting a compressor 50 (not shown) is provided at the tip of the on-off valve side pipe line 38 located in the internal space 70. The pressure accumulator side pipe 41 branches into three and is connected to the pressure accumulator 40, the diffusion valve 33b, and the on-off valve 37b. A connecting device 39b is provided downstream of the pipeline in which the on-off valve 37b is provided. The connection tool 39b is for connecting the compressor 50 which supplements the fluid to the pressure accumulator 40 when the residual pressure of the pressure accumulator 40 decreases. The accumulator 40 is installed at a predetermined location on the floor surface 4 of the base 2. The accumulator 40 is used as a fluid supply unit that supplies fluid. The pressure accumulator 40 supplies fluid to the internal space 70 of the bag-shaped member 30 when the pressure detected by the pressure detection unit 35 reaches a predetermined pressure.

  FIG. 7 is a plan view of the safety device 1 according to the first embodiment of the present invention. FIG. 7 shows the movement of the fluid in the bag-like members 30a and 30b. Fig.7 (a) is a figure which shows the state of the bag-shaped members 30a and 30b in a cancellation | release state. The bag-like members 30a, 30b, and 30c are filled with a uniform amount of fluid. The pressure of the fluid is the same as the ambient pressure, here atmospheric pressure. At this time, the cock 34b provided between the bag-like member 30a and the bag-like member 30b is opened, and the cocks 34a and 34d are closed. The fluid in the bag-like members 30a, 30b, and 30c can move through the communication pipe 31 in the bag-like members 30a, 30b, and 30c. After the passenger 7 is seated on the seat 3, the movement restriction unit 10 moves from the released state to the restricted state, that is, the direction indicated by the arrow in FIG. 3. The movement restricting portion 10 is displaced until the bag-like members 30a, 30b, 30c can come into contact with the occupant 7 and is fixed when the bag-like members 30a, 30b, 30c can come into contact with the occupant 7.

  FIG.7 (b) is a figure which shows the state of the bag-shaped member 30 in a restriction | limiting state. In the seat 3, a large passenger 7A and a small passenger 7B are seated. There is a physique difference between the passenger 7A and the passenger 7B. The distance of this physique difference is indicated by ΔL1. The movement restricting portion 10 is angularly displaced, and the bag-like member 30 supported by the movement restricting portion 10 is brought into contact with the abdomen of the occupant 7A. At this time, the bag-like member 30b and the passenger 7B are separated by ΔL1. When the movement restricting portion 10 is further displaced toward the passengers 7A and 7B, the fluid in the bag-like member 30a is pressed by the passenger 7A and moves into the bag-like member 30b through the communication pipe 31. When the fluid in the bag-shaped member 30a moves into the bag-shaped member 30b, the bag-shaped member 30b swells toward the passenger 7B. When the bag-like member 30b is inflated by ΔL1 due to the movement of the fluid in the bag-like member 30a, the bag-like member 30b comes into contact with the abdomen of the passenger 7B.

FIG.7 (c) is a figure which shows the movement of the fluid in the state of FIG.6 (b). In FIG.7 (c), the area | region 18 where the fluid which was pushed and moved is located is shown with a diagonal line. As shown in FIG.7 (c), the fluid in the bag-shaped member 30a pressed by the passenger 7A moves to the bag-shaped member 30b, and the bag-shaped member 30a is made concave in accordance with the body shape of the passenger 7A. Deform. On the other hand, the fluid moved from the bag-like member 30a flows into the bag-like member 30b, and the bag-like member 30b swells toward the passenger 7B and deforms according to the body shape of the passenger 7B. The movement restricting unit 10 is fixed at a position where the pressing force of the passenger 7A against the bag-like member 30a and the pressing force of the passenger 7B against the bag-like member 30b are uniform. When a predetermined pressing force cannot be applied to each occupant 7A, 7B only by displacement of the movement restricting unit 10, a fluid may be supplied using the pressure accumulator 40. A desirable range of pressure to be applied to the passenger 7 is empirically 4-5 kgw / cm ² (kilogram weight per square centimeter).

  The vehicle 100 accelerates and decelerates as part of the play-related effects. When the vehicle 100 accelerates and decelerates, acceleration is applied to the occupant 7, and a pressing force is applied to the body of the occupant 7 from at least one of the seat 3, the floor surface 4, and the bag-shaped member 30. The bag-like member 30 of the present embodiment is formed to have a thickness that can withstand at least the same load as the weight of the passenger 7. As a result, the bag-like member 30 can keep the fluid in the internal space 70 airtight without being damaged even if a load due to the weight of the passenger 7 acts due to acceleration and deceleration of the vehicle 100.

  Further, as described above, the bag-like member 30 is formed of a member having rubber elasticity. As a result, the bag-like member 30 causes the body of the passenger 7 on the support member 12 when the vehicle 100 is accelerated or decelerated and acceleration is applied to the passenger 7 and a pressing force is applied to the bag-like member 30. The surface area can be expanded by extending away from the closest proximity position A1. Therefore, compared with the case where the surface area of the bag-shaped member 30 does not change, the area which gives a pressing force to the passenger 7 can be expanded, and the pressure applied to the passenger 7 can be made small.

  However, if the elastic modulus of the bag-shaped member 30 is too large, for example, the fluid interposed between the support member 12 and the occupant 7 at the proximity position A1 shown in FIG. Therefore, the elastic modulus of the bag-shaped member 30 is at least the support member 12 and the passenger 7 when the vehicle 100 is accelerated or decelerated and acceleration is applied to the passenger 7 and a pressing force is applied to the bag-shaped member 30. It is preferable to set an appropriate range so as to leave a space in which fluid can exist. As a result, the fluid can always be positioned between the body of the passenger 7 and the support member 12, and the pressure applied to the body of the passenger 7 can be distributed.

  In the restricted state, the support member 12 is angularly displaced until the bag-shaped member 30 contacts the body of the occupant 7, so that the occupant 7 presses or grips the buffer member 13 from the front X1 rather than the support portion 12b. be able to. At this time, the pressing force applied to the buffer member 13 is applied from the buffer member 13 to the support portion 12 b, but is not applied to the bag-shaped member 30. Therefore, even when the occupant 7 presses or grips the buffer member 13, it is possible to avoid an increase in pressure that acts on the abdomen of the occupant 7 from the bag-shaped member 30. Thereby, the ride quality of the passenger 7 can be improved.

  According to the first embodiment, the pressure accumulator 40 supplies the fluid to the internal space 70 of the bag-like member 30 via the pipe line when the pressure of the fluid detected by the pressure detector 35 reaches a predetermined pressure. To do. For example, when acceleration is generated by acceleration or deceleration of the vehicle 100, a pressing force due to an inertial force is applied to the occupant 7, and the pressing force of the occupant 7 on the movement restriction unit 10 changes. Thus, when the magnitude of the pressing force on the movement restriction unit 10 of the passenger 7 reaches a predetermined magnitude, the pressure accumulator 40 supplies fluid. Therefore, the safety device 1 increases the amount of fluid in the internal space 70 of the bag-like member 30 when the fluid pressure in the internal space 70 of the bag-like member 30 reaches a predetermined pressure, Since the fluid can be reliably interposed between the movement restricting portion 10 and the passenger 7 and the movement restricting portion 10 can be prevented from directly applying a pressing force to each other. Moreover, since the safety device 1 can disperse the mutual pressing force between the occupant 7 and the movement restriction unit 10 by the fluid in the bag-like member 30, the occupant 7 and the movement restriction unit 10 can Compared with the case where the direct pressing force is applied to each other, the mutual pressing force between the passenger 7 and the movement restriction unit 10 can be reduced.

  Further, according to the first embodiment, the movement restriction unit 10 restricts the movement of each passenger 7 at a position where the pressing force of each passenger 7 against each bag-like member 30 is uniform. Accordingly, the same pressure can be applied to the passenger 7 in any seat 3. Therefore, the fit feeling of the passenger 7 can be improved, and the sense of security of the rider 7 with respect to the vehicle 100 can be increased.

  Moreover, according to 1st Embodiment, the safety device 1 can control the quantity of the fluid in the bag-shaped member 30 using the pressure detection part 35 and the pressure accumulator 40, and also can detect the leakage of the fluid. it can. In addition, by closing the cocks 34a, 34b, 34c, 34d, the internal space 70 and the internal space 70 of the bag-like member 30 adjacent to each other via the cocks 34a, 34b, 34c, 34d with respect to the communication by the pipe line, The fluid can be prevented from moving. Thereby, it is possible to prevent the fluid pressure in the bag-shaped member 30 from affecting the fluid pressure in the adjacent bag-shaped member 30 via the cocks 34a, 34b, 34c, and 34d with respect to communication through the pipe line. Further, the safety device 1 includes cocks 34a and 34b in which the bag-like member 30 corresponding to the seat 3 where the passenger 7 is seated and the bag-like member 30 corresponding to the empty seat 3 where the passenger 7 is not seated are connected to the cocks 34a and 34b. , 34c, 34d, the bag-like member 30 corresponding to the seat 3 where the passenger 7 is not seated is moved against the fluid movement in the bag-like member 30 corresponding to the seat 3 where the passenger 7 is seated. Can be prevented.

  The vehicle 100 to be used by the safety device 1 according to the present invention is an amusement vehicle. Therefore, the ride comfort required for the vehicle 100 is different from the ride comfort required for vehicles such as moving and transporting. The pressing force applied to the occupant 7 by the acceleration of the vehicle 100 is important as a part of the presentation provided to the occupant 7, unlike a vehicle other than a game such as moving. Therefore, reducing the acceleration and the pressing force caused thereby may hinder the function of the vehicle 100 for play. Therefore, reducing the magnitude of the acceleration and reducing the pressing force applied to the passenger 7 is different from the function required for the safety device 1 used for the vehicle 100. The safety device 1 used for the vehicle 100 needs to improve the ride comfort of the passenger 7 without reducing the magnitude of the acceleration that affects the passenger 7.

  Therefore, in order to provide the vehicle 100 with good ride comfort to a plurality of passengers 7 without reducing the pressing force exerted on the body of the passenger 7 by acceleration, the pressing force applied to the body of the passenger 7 Therefore, it is necessary not to cause a bias by the passenger 7. If there is a bias in the pressing force, there is a possibility that riding comfort or a sense of security may be impaired because the pressing force is too large or too small. Therefore, the pressing force applied to the plurality of passengers 7 is reduced. It is necessary and important to be identical to each other.

  Further, in the vehicle 100, unlike the vehicle for movement, a plurality of passengers 7 board the vehicle almost at the same time and leave the vehicle almost at the same time. Therefore, in the vehicle 100, it is preferable that the time required for boarding and leaving the passenger 7 is as short as possible. Therefore, the configuration of the present embodiment that can hold the bodies of a plurality of passengers 7 in one step is a preferable configuration because the steps necessary for the operation of the vehicle 100 can be reduced.

  The safety device 1 according to the present embodiment has a configuration in which internal spaces 70 of a plurality of bag-like members 30 arranged side by side in correspondence with a plurality of seats 3 are communicated with each other by a connecting pipe 31, and an internal space The configuration in which the fluid located at 70 can be moved into the plurality of bag-like members 30 reduces the number of steps required for the operation of the vehicle 100 and the same and good ride comfort for the plurality of passengers 7. Providing the vehicle 100 can be compatible with each other.
