Description

[Technical Field]

[0001] The present invention relates to a protective waist belt and safety device for motorcycle riders, which is fitted with a waist belt incorporating an airbag tube, and which supplies inflation gas to the airbag tube in the event of a collision, thereby expanding the airbag tube to envelop the rider's front and back, thereby protecting the rider. [Background technology]

[0002] Motorcycles (also known as bikes, motor cycles, or two-wheeled vehicles) are driven with the driver seated in the driver's seat and without any additional safety devices. Therefore, in the event of an accident such as a collision or rear-end collision, the driver may fall over or be thrown forward as the motorcycle falls, leaving the driver with no protection. Therefore, various efforts are being made to reduce injuries to drivers.

[0003] One of these involves placing an airbag tube of a certain size inside the jacket or trousers worn by the driver, and placing a nitrogen tank on one side of the jacket to inflate the airbag tube. However, because the driver must be able to move freely while wearing the jacket or trousers, and the size of the nitrogen tank cannot be made unnecessarily large, only enough gas is supplied to partially inflate the airbag tube, which means that in the event of a collision, the impact on the driver is only partially cushioned, and parts of the driver not covered by the jacket or trousers cannot be prevented from being damaged by the impact.

[0004] Thus, when airbag tubes are built into jackets, trousers, etc. to protect motorcyclists, it is not possible to enlarge the size of the airbag tube unnecessarily, and since the amount of nitrogen gas supplied to the airbag tube is insufficient, the airbag tube can only expand to a certain volume, so complete cushioning function of the airbag tube cannot be expected, and one must be satisfied with only cushioning fatal impacts. Furthermore, even if wearing a jacket, trousers, or helmet with built-in airbag tubes can protect parts of the rider's upper and lower body, the safety of the rider's arms, face, or legs cannot be guaranteed.

[0005] In other words, exposed parts of the driver's body, such as the shoulders and legs, cannot be adequately protected by airbag tubes built into jackets and trousers, so there is currently a demand for safety devices that can provide sufficient protection for the driver.

[0006] Meanwhile, Korean Patent Publication No. 10-2015-0125679 discloses a protection system in which an airbag tube is built into the seat of a motorcycle driver. However, this prior art has the problem that the driver's seat is high and difficult to drive because the protection system is installed in the seat where the driver sits, and because the protection system is manufactured as a single unit with the motorcycle, it cannot be applied to other motorcycles.

[0007] [Patent Document 1] Korean Patent Publication No. 10-2015-0125679 (Published on November 9, 2015) [Patent Document 2] Japanese Utility Model Registration No. 3070441 (registered August 4, 2000) [Patent Document 3] U.S. Patent Publication No. US2011 / 0237194 (registered September 29, 2011) [Patent Document 4] Japanese Patent Publication No. 2010-163136 (Published on July 29, 2010) Summary of the Invention [Problem to be solved by the invention]

[0008] The present invention aims to solve the problems of an insufficient amount of nitrogen gas being supplied to the airbag tubes built into jackets worn by motorcyclists in the event of a collision, causing the airbag tubes to not expand sufficiently, the problem of the airbag tubes not being able to fully enclose the shoulders, legs or face, which are vulnerable to injury, and the problem of the rider being restricted in their activities when wearing a jacket with a built-in airbag tube because the jacket is thick.The purpose of this invention is to reduce fatal accidents by having a waist belt with a built-in airbag tube worn around the waist of a motorcyclist, and by having a sufficient amount of nitrogen gas being supplied so that the airbag tubes expand to enclose the entire front and back of the rider in the event of a collision.

[0009] In particular, the present invention aims to move away from the method of minimizing damage caused by the inability of the airbag tube of a jacket with a built-in airbag tube to inflate sufficiently due to the shape of the jacket, and to protect the driver by ensuring that the airbag tube is inflated sufficiently. [Means for solving the problem]

[0010] In this invention, an airbag tube is built into the waist belt worn around the waist of the rider, and the airbag tube expands above and below the waist belt when nitrogen gas is supplied. The airbag tube is supplied with nitrogen gas from a nitrogen tank in a gas supply device built into the motorcycle driver's support stand, or from a nitrogen tank suspended behind the waist of the waist belt. When a collision accident is detected, nitrogen gas from the nitrogen tank is supplied to the airbag tube, causing it to inflate. When inflated, the airbag tube expands above and below the waist belt into a shape that fully envelops the rider, protecting the rider from impact.

[0011] The waist belt of the present invention is worn by a driver, and has a folded airbag tube built into the waist belt that expands upward and downward when nitrogen gas is supplied. The airbag tube expands to envelop the driver from the chest to the face, and also expands to envelop the driver's sides and back. The airbag tube is normally kept folded inside the waist belt, and when nitrogen gas is supplied, it expands upward and downward from the waist belt and expands to envelop the driver's front and back sufficiently to protect the driver.

[0012] The airbag tube built into the waist belt of the present invention has an exposure groove on the side to expose the arms so that they are tucked under the armpits when inflated, while the airbag tubes on the front and back are joined together with a thin patch cloth.

[0013] The airbag tube built into the waist belt of the present invention is supplied with nitrogen gas from a gas supply device built into the motorcycle driver's cradle, and a fixed belt connected to the gas supply device and a movable belt connected to the waist belt are fastened together via a connecting device. The gas supply device has a built-in nitrogen tank that supplies a sufficient amount of nitrogen gas to expand the airbag tube, and is normally kept fixed to the driver's cradle by a locking device. In the event of a collision, the locking device is released and the gas supply device is detached from the driver's cradle, and the nitrogen gas filled in the nitrogen tank of the gas supply device is supplied to the airbag tube of the waist belt by an opening and closing device, and the airbag tube expands to wrap around the front and back of the rider, providing protection.

[0014] The gas supply device and waist belt of the present invention allow the fixed belt and movable belt to be fastened together via a fastening device, which consists of a female fastener fixed to the fixed belt and a male fastener fixed to the movable belt. Pipes are built into the female and male fasteners, and when the female and male fasteners are fastened together, the pipes are joined and engaged with each other to supply nitrogen gas. However, the female and male fasteners maintain their connected state unless a release button is pressed. When the rider sits on the motorcycle seat, the fastened state is maintained via the fastening device, and when the rider leaves the motorcycle seat, the fastening device is released to allow freedom of movement. The pipe of the female fastener is elastically supported by a spring, so that a tight fit is maintained when the pipe of the male fastener is fitted in.

[0015] In addition, the present invention fixes a nitrogen tank to the back of the waist belt worn by the rider so that it can move with the rider when wearing the waist belt, and the nitrogen gas filled in the nitrogen tank is supplied to the airbag tube of the waist belt through a gas opening and closing device. One side of the gas opening and closing device is fastened to a collision detection string, the other side of which is fixed to the motorcycle, with a loop, and when a collision accident occurs, the collision detection string connected to the gas opening and closing device is pulled strongly, causing the nitrogen gas in the nitrogen tank to inflate the airbag tube, protecting the rider.

[0016] The present invention recognizes a collision detection signal that detects a motorcycle collision and transmits it as a Bluetooth signal, and the Bluetooth signal activates a gas opening and closing device, which supplies nitrogen gas from a nitrogen tank fixed to the back of the waist on the waist belt to the airbag tube on the waist belt, thereby inflating the airbag tube. [Effects of the Invention]

[0017] This invention has the effect that when a driver wearing a waist belt is involved in an accident while driving, a sufficient amount of nitrogen gas is supplied to the airbag tube built into the waist belt, causing the airbag tube to expand into a shape that envelops the front and back of the driver, thereby significantly reducing the impact on the driver in the event of a collision accident and also reducing the risk of injury.

[0018] The present invention allows the rider to travel while wearing a waist belt, and the waist belt is connected to the gas supply device only when the rider is riding a motorcycle. In the event of a collision, the gas supply device remains connected to the waist belt and supplies a sufficient amount of nitrogen gas, thereby ensuring reliable expansion of the airbag tube.

[0019] The present invention allows nitrogen gas to be supplied from a nitrogen tank fixed to the back of the waist belt without being supplied from a gas supply device built into the driver's seat.

[0020] The present invention solves the problem that the degree of inflation of the airbag tube cannot be increased as in the case of conventional jackets with built-in airbag tubes, because the driver usually wears a waist belt while moving around. However, the present invention ensures that the driver can move freely without being restricted in his / her activities, and in the event of a collision, the airbag tube expands to a shape that fully envelops the front and back of the driver, thereby effectively protecting the driver from impact.

[0021] The present invention has the advantage that the driver can normally wear the waist belt while in motion, ensuring easy wearing and mobility, and when driving, the waist belt is connected to the connecting device, and in the event of a collision, a sufficient amount of nitrogen gas is supplied, allowing the airbag tube to expand sufficiently to protect the driver.

[0023] The present invention relates to a waist belt that has an airbag tube built in and expands to envelop the front and back of the rider when nitrogen gas is supplied. The waist belt is worn by the motorcycle rider while driving, but can also be detached from the motorcycle and moved around. Therefore, if a collision occurs while riding, the airbag tube of the waist belt expands to envelop the front and back of the rider, protecting the rider, but the rider can normally move freely with the waist belt still worn around the waist.

[0024] The airbag tube built into the waist belt of the present invention is supplied with nitrogen gas from a nitrogen tank in a gas supply device built into the motorcycle driver's support stand, or from a nitrogen tank fixed to the back of the waist belt.When sitting on the seat to drive the motorcycle, the waist belt and gas supply device are connected by a connecting device before driving, or the collision detection cord is connected before driving.If a collision occurs while driving, nitrogen gas is supplied to the airbag tube of the waist belt by the connecting device or collision detection cord, causing it to expand into a shape that wraps around the front and back of the rider.When the rider leaves the motorcycle, the connecting device and collision detection cord can be removed, allowing the rider to move freely.

[0025] In this invention, when an airbag tube built into the waist belt worn by the rider is inflated, the airbag tube receives a sufficient amount of nitrogen gas and expands into a shape that envelops the front and back of the rider, so that even if the motorcycle rider is separated from the motorcycle in the event of a collision accident, he or she can be protected by the expanding airbag tube.

[0026] In the present invention, the waist belt worn by the driver has an airbag tube built in that expands into a shape that fully envelops the front and back of the driver when inflated, and the nitrogen gas supplied to the airbag tube is supplied from a nitrogen tank. The nitrogen tank is built into a gas supply device arranged in the driver's seat and connected to the waist belt before the driver starts driving so that nitrogen gas is supplied to the airbag tube when a collision occurs, or the nitrogen tank is hung behind the driver's waist so that nitrogen gas inflates the airbag tube when a collision occurs.

[0027] In the present invention, the former method detects a collision accident using a collision detection sensor and supplies nitrogen gas from the nitrogen tank to the airbag tube of the waist belt, and the latter method detects the driver's departure when a collision accident occurs using a collision detection cord, or supplies nitrogen gas from the nitrogen tank to the airbag tube of the waist belt in response to a detection signal transmitted as a Bluetooth signal.

[0028] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0029] The present invention relates to a waist belt 10 worn around the waist of a rider 3, and the rider 3 wears the waist belt 10 only when driving a motorcycle 1. The waist belt 10 has built-in airbag tubes 11, 12, which expand up and down as nitrogen gas is supplied to them, and the airbag tubes 11, 12 that expand in the waist belt 10 expand into a shape that fully envelops the front and back of the rider 3, protecting the rider in the event of a collision accident.

[0030] In the present invention, when a rider wears a waist belt 10 with built-in airbag tubes 11, 12 and rides a motorcycle 1, in the event of a collision, a sufficient amount of nitrogen gas is supplied to the airbag tubes 11, 12, causing them to inflate and envelop the front and back of the rider 3, thereby protecting the rider 3. This provides a significant difference in terms of rider protection compared to existing jackets with built-in airbags, which have limited inflation capacity.

[0031] The airbag tube 11 of the present invention is joined with a thin patch cloth 13 at the portion sandwiched under the armpits so that when it inflates upward, it is fitted into the armpit area while inflating, and an exposed groove 14 is formed in the portion where the arm is fitted, so that when a collision accident occurs, the airbag tubes 11, 12 inflate to envelop the front and back of the driver, and during this process, the arms are fitted into the exposed groove 14 while the patch cloth 13 is fitted into the armpits.

[0032] In the present invention, a waist belt 10 is worn only when driving a motorcycle 1, and nitrogen is supplied to the airbag tubes 11, 12 built into the waist belt 10 from a nitrogen tank built into a gas supply device 50 arranged in the driver's seat 2, or from a nitrogen tank 51 fixed to the back of the waist belt 10. Below, the case where the gas supply device 50 is used will be explained first, and the case where the nitrogen tank 51 is used will be explained later.

[0033] In order to use nitrogen gas from the nitrogen tank built into the gas supply device 50, first, a movable band 20 of a certain length is fixed integrally to the rear of the waist belt 10, and the male connector 31 of the connector device 30 is connected to the tip of the movable band 20. A pipe 21 is built into the interior of the movable band 20, so that when the male connector 31 is connected to the female connector 32, nitrogen gas is supplied to the airbag tubes 11 and 12 built into the waist belt 10 via the pipe 21.

[0034] The waist belt 10 of the present invention can be fastened and undone in front of the driver 3 like a normal belt, and forms a movable band 20 of a certain length behind the waist belt 10. Airbag tubes 11 and 12 are built into the waist belt 10 and separated into upper and lower tubes. When nitrogen gas is supplied to the airbag tubes 11 and 12, the airbag tubes 11 and 12 expand to the upper and lower sides, but expand so as to enclose the face and feet of the driver 3.

[0035] The airbag tubes 11, 12 built into the waist belt 10 usually remain built in, so there are no restrictions on the activities of the rider 3. In particular, since the movable belt 20 is fastened to the connecting device 30 at a fixed length, slight movements while riding can be made without feeling limited by the length of the movable belt 20. When the rider has finished riding and wishes to leave the motorcycle 1, the movable belt 20 is removed from the connecting device 30, so there are no restrictions on the rider's activities even while wearing the waist belt 10.

[0036] In other words, the waist belt 10 of the present invention is worn by the driver 3, and has airbag tubes 11 and 12 built into the waist belt 10 that expand upward and downward, and the airbag tubes 11 and 12 expand to envelop the front and back of the driver when inflated.The airbag tubes 11 and 12 are normally kept built into the waist belt 10, and when nitrogen gas is supplied, they expand and expand to envelop the front and back of the driver 3, protecting the driver 3.

[0037] On the other hand, the gas supply device 50 of the present invention has a built-in nitrogen tank 51 that supplies a sufficient amount of nitrogen gas to expand the airbag tubes 11 and 12 built into the waist belt 10, and is normally kept fixed inside the driver's platform 2 by a locking device 70.However, when a collision accident occurs, the locking device 70 is released by an electrical signal supplied from a collision detection sensor (not shown), allowing the gas supply device 50 to be removed from the driver's platform 2.

[0038] The gas supply device 50 is normally installed inside the driver's platform 2 and is prevented from detaching by a locking device 70. When a collision signal is supplied due to a collision accident, the locking device 70 is released, and the gas supply device 50 becomes detachable from the driver's platform 2. The gas supply device 50 can be connected using a separate locking means (not shown) or installed in a location other than the driver's platform 2, but the gas supply device 50 must normally remain fixed and become detachable when a collision accident occurs, and must also be able to supply a sufficient amount of nitrogen gas to inflate the airbag tubes 11 and 12.

[0039] The nitrogen gas filled in the nitrogen tank 51 of the gas supply device 50 is sprayed out by the built-in opening and closing device 60, and the opening and closing device 60 is opened and closed in response to a detection signal from a collision accident detection sensor (not shown).The gas supply device 50 is fixed to a fixing belt 40, and a pipe 41 is built into the fixing belt 40, and the nitrogen gas filled in the nitrogen tank 51 of the gas supply device 50 is selected to be supplied to the pipe 41 via the opening and closing device 60.

[0040] That is, the nitrogen gas filled in the nitrogen tank 51 is normally kept in a state where its discharge is blocked by the opening and closing device 60, and when a collision accident occurs, the opening and closing device 60 supplies the nitrogen gas to the pipe 41, whereby the nitrogen gas is supplied to the airbag tubes 11 and 12 and inflation occurs.

[0041] In the present invention, male and female couplers 31 and 32 that constitute the coupling device 30 are arranged at the ends of the fixed band 20 and the movable band 40. When the male and female couplers 31 and 32 are fastened, nitrogen gas is supplied from the pipe 41 to the pipe 21, and when the male and female couplers 31 and 32 are separated, the supply of nitrogen gas is cut off.

[0042] In the present invention, when the male coupler 31 is fitted into the female coupler 32, it is fastened by a normal fastening means, and when it is to be removed, it is removed by pressing a release button (not shown). This allows nitrogen gas to be supplied to the normal coupling device 30 when the male coupler 31 is fitted into the female coupler 32 and when the male coupler 31 is removed from the female coupler 32.

[0043] In the present invention, a pipe 21 is built into the male coupler 31, and the pipe 21 is built into the movable band 20. A pipe 41 is also built into the female coupler 32, and the pipe 41 is built into the fixed band 40. When the male coupler 31 is fitted into the female coupler 32 to complete the coupling device 30, the pipe 21 is fitted into the pipe 41, completing the connection of the pipe 2141 and completing the nitrogen gas supply line.

[0044] Here, in order to increase the adhesive force of the pipe 41 and ensure smooth supply of nitrogen gas, the pipe 41 is made to maintain a state in which it is elastically supported by the spring 33 .

[0045] Therefore, in the present invention, when riding the motorcycle 1, the rider 3, while wearing the waist belt 10, fits the movable band 20 into the connecting device 30 and connects it to the fixed band 40, so that in the event of a collision, the gas supply device 50 will be detached by the impact, and nitrogen gas from the nitrogen tank 51 will be supplied to the airbag tubes 11, 12 of the waist belt 10 via the opening and closing device 60, causing the airbag tubes 11, 12 to expand.After safely operating the motorcycle 1, when the rider 3 wishes to dismount from the motorcycle 1, the movable band 20 and the fixed band 40 can be removed from the connecting device 30, allowing the rider 3 to move freely.

[0046] In the present invention configured as described above, when the rider 3 drives the motorcycle 1 while wearing the waist belt 10, the rider drives with the coupling device 30 coupled as shown in FIG. 1, and when the rider 3 wants to detach from the motorcycle 1, the coupling device 30 is removed as shown in FIG. 2, ensuring the rider 3's freedom of movement. If a collision occurs while riding the motorcycle 1, the rider 3 will be released to the front of the motorcycle 1 as shown in FIG. 3, and in the present invention, the gas supply device 50 will be released together with the waist belt 10 while still coupled to it as shown in FIG. 4.

[0047] In the present invention, the rider 3 drives the motorcycle with the movable strap 20 of the waist belt 10 worn by the rider 3 and the fixed strap 40 of the gas supply device 50 arranged on the driver's stand 3 connected by the connecting device 30, and during this process, the rider 3 can move normally due to the length of the movable strap 20, and at the moment of a collision accident, the connecting device 30 will be detached from the motorcycle 1 together with the rider 3, while still connected to the waist belt 10 by the fixed strap 40 and the movable strap 20 without being removed.

[0048] In other words, the male and female couplings 31, 32 of the coupling device 30 will not separate unless a separate release button is pressed, so that when a collision occurs, the coupling device 30 will not be removed, and the locking device 70 and the opening and closing device 60 will be released by the detection signal of the sensor that detects the collision, so that at the same time as the collision occurs, the gas supply device 50 will be removed from the driver's stand 2 and the nitrogen gas in the nitrogen tank 51 will be discharged.

[0049] Therefore, the gas supply device 50 is detached together with the driver 3 while remaining connected to the waist belt 10, and during this process, nitrogen gas from the nitrogen tank 51 is supplied to the airbag tubes 11 and 12 via the pipe 4121, causing the airbag tubes 11 and 12 to expand into a shape that envelops the front and back of the driver 3, thereby preventing injury to the driver 3 and reducing the impact.

[0050] In the present invention, when a collision accident occurs, the gas supply device 50 remains connected to the waist belt 10 and is detached together with the driver 3, thereby expanding the airbag tubes 11, 12. During this process, the nitrogen tank 51 of the gas supply device 50 is filled with a sufficient amount of nitrogen gas to expand the airbag tubes 11, 12, so the process of expanding the airbag tubes 11, 12 to a shape that envelops the front and back of the driver 3 is not strained.

[0051] On the other hand, in the present invention, as shown in Figures 13 to 15, a nitrogen tank 51 is fixed integrally to the back of the waist of the waist belt 10 worn by the rider 3 so that it can move together with the rider 3 when wearing the waist belt 10, and the nitrogen gas filled in the nitrogen tank 51 is supplied to the airbag tubes 11 and 12 of the waist belt 10 through a gas opening and closing device 55. The gas opening and closing device 55 has one end of a collision detection string 56 fixed to the motorcycle 1 and the other end of the string fastened to the loop, so that when a collision accident occurs, the collision detection string 56 connected to the gas opening and closing device 55 is pulled strongly and the nitrogen gas in the nitrogen tank 51 is supplied to the airbag tubes 11 and 12, inflating the airbag tubes 11 and 12 and enveloping the front and back of the rider 3 for protection.

[0052] Here, the collision detection cord 56 is connected to the gas opening and closing device 55 by a loop when the driver 3 gets in the car, and when the driver 3 is hit by a force that throws him / her forward in a collision accident, the collision detection cord 56 is pulled, activating the gas opening and closing device 55, which causes the nitrogen gas filled in the nitrogen tank 51 to be supplied to the airbag tubes 11 and 12 of the waist belt 10 and inflate them, thereby ensuring the safety of the driver 3. Normally, the gas opening and closing device 55 will not be activated by a slight pull by the driver 3 during driving, but will only be activated when pulled by a strong impact.

[0053] In other words, normally, the rider 3 leaves the motorcycle and moves around with the nitrogen tank 51 hanging from the waist belt 10 behind the rider's waist without the collision detection cord 56 connected, and when driving the motorcycle 1, the rider sits in the driver's seat and connects the collision detection cord 56 to the gas opening and closing device 55 by hooking the loop thereon, and when leaving the driver's seat, the rider again detaches the loop from the gas opening and closing device 55.

[0054] In the present invention configured as described above, the nitrogen tank 51 is fixed integrally to the waist belt 10 worn by the rider 3 behind the waist, so that the nitrogen tank 51 moves integrally with the rider 3 when the waist belt 10 is worn. When riding the motorcycle 1, the collision detection cord 56 is connected to the gas opening and closing device 55 fixed to the waist belt 10, and when not riding the motorcycle 1, the loop of the collision detection cord 56 is removed to release the connection to the gas opening and closing device 55.

[0055] When the rider 3 sits in the driver's seat of the motorcycle 1 to drive, the rider 3 drives with the loop of the collision detection cord 56 connected to the gas opening and closing device 55 by a loop. If a collision occurs in this state, the rider 1 will be thrown forward by inertia, and in the process, the collision detection cord 56 will be pulled, activating the gas opening and closing device 55. The nitrogen gas filled in the nitrogen tank 51 by the activation of the gas opening and closing device 55 will be supplied to the airbag tubes 11 and 12 of the waist belt 10 via the gas opening and closing device 55. As a result, the airbag tubes 11 and 12 of the waist belt 10 will inflate and wrap around the front and back of the rider 3, protecting the rider 3 from a collision.

[0056] That is, normally, the rider 3 can move around with the nitrogen tank 51 hanging behind the waist belt 10 without connecting the collision detection string 56, and there is no problem with movement other than the fact that the nitrogen tank 51 is filled behind him, and when he is driving the motorcycle 1, he sits in the driver's seat and hooks the collision detection string 56 to the gas opening and closing device 55 by looping it. In the event of a collision, the gas opening and closing device 55 will be activated and nitrogen gas from the nitrogen tank 51 will be supplied to the airbag tubes 11 and 12 to protect the rider 3.

[0057] In addition, the present invention recognizes a collision detection signal that detects a collision of the motorcycle 1 and generates it as a Bluetooth signal, and when the gas opening and closing device 55 detects the Bluetooth signal, it operates to supply nitrogen gas, thereby supplying nitrogen gas from a nitrogen tank 51 fixed to the back of the waist of the waist belt 10 to the airbag tubes 11 and 12 of the waist belt 10, and inflating the airbag tubes 11 and 12 into a shape that wraps around the front and back of the rider.

[0058] The present invention eliminates the inconvenience of having to fasten and untie the collision detection string 56 when the rider 3 gets on or off the motorcycle 1. When the rider 3 gets on the motorcycle 1, a Bluetooth connection is made, and a collision signal generated in this state is transmitted as a Bluetooth signal, and nitrogen gas from the nitrogen tank 51 is supplied to the airbag tubes 11 and 12 of the waist belt 10, causing them to inflate, expanding into a shape that wraps around the front and back of the rider 3 and protecting the rider.
