    Safety silencer to protect vehicle occupants
    Field of the Invention
    The invention relates to vehicles and vehicle safety damper solutions, such as driver and passenger seat safety shock absorber protection solutions, in particular those intended to protect vehicle users.
    Background of the Invention
    Vehicles, such as highways, rails, or off-road vehicles, may need to be prepared for accelerating forces higher than those of explosions or impacts. Such higher than normal accelerating forces were caused, for example, by severe collisions or explosions.
    A variety of vehicles and protective vehicles, such as protective trucks, armored trucks, and protective or armored vehicles 15, have been used to protect against explosions such as vehicle mines and improvised explosive devices, improvised explosive devices, or improvised bombs. Other protective vehicles include, for example, radar system vehicles, anti-aircraft missile systems vehicles, ambulance vehicles, security intelligence vehicles, command20 space vehicles, repair vehicles, communication systems vehicles, vehicle warfare vehicles, racing vehicles, armored vehicles, armored vehicles, A roadside bomb is an explosive that is usually placed on the roadside and fired, with remote control, when 25 vehicles are in sight.
    The passenger compartment of a vehicle or protective vehicle and its supporting structures are subjected to extremely violent forces, for a very short period of time, due to the shock wave generated by the explosion under the vehicle. The forces give the cab structures a very high acceleration which, despite its short duration, still gives rise to a high speed of movement.
    The human body, and especially the spine of a person in a sitting position, does not withstand such violent acceleration, so the accelerator forces on the seat must be reduced to a tolerable level with the seat training system.
    20175700 prh 25 -07- 2017
    Acceleration can only be slightly dampened by flexible seat cushions. Effective restraint is sufficiently effective only by the yielding, damping seat support structures.
    During the damping stroke, a large amount of energy is transferred to the seat suspension system, most of which is charged with potential energy to the elastic spring of the suspension system by conventional suspension systems. The energy of the spring tends to move backward towards its seat after the seat has reached the same speed of movement as the cabin structures. A poorly suited, overly elastic seat suspension may, in the aftermath, even kick the seat 10 towards the roof structure of the cab.
    The shock wave of an explosion under a car throws a vehicle, such as an armored vehicle, in a very violent, momentary acceleration upwards and cannot be tolerated by the human body without injury. Acceleration is an almost impulsive sudden output, resulting in a moderately high upward motion speed for steel structures that remain stable throughout the vehicle.
    To protect against the effects of an explosion, the seat support system must also be able to absorb another similar collision immediately, as a vehicle thrown into the air by the explosion may collide very hard with the ground or other object below. The vehicle's wheel (s) and wheel suspension system may have been almost completely destroyed in the event of an explosion.
    The Dynamic Response Index (DRI), originally given in the relevant internationally used classification scheme for the use of airship seats, provides a maximum allowable acceleration value of G in the spine of 17 in the relevant internationally used classification model.
    Numerous different seat damping solutions have been developed for vehicles or protective vehicles. There are also several working principles of known damping solutions, such as elastic strings with lever mechanisms and / or viscous dampers, tear belts knuckles and plastic deformation dampers.
    Existing vehicle silencer protection solutions are often highly sophisticated high-tech devices, typically complex and very expensive.
    Nowadays, there is a clear need and demand for new types of safety damper solutions in vehicles, and also in protective vehicles,
    20175700 prh 25 -07-2017, which provide more cost-effective and efficient protection of vehicle occupants from acceleration forces caused by explosions or severe collisions.

According to one embodiment of the invention, the safety damper for protecting vehicle users comprises damping elements 11, 12, first fastening elements 2, a movable locking element 3, a counter element 4 and a gas spring 5.
    The damping element 11, 12 according to an embodiment of the invention comprises a basic damping wire 11 bent to a helical coil and an auxiliary wire 12 twisted to a helical coil 12. , 12 parts to another seat part of said non-damped seat part and said safety damped seat part.
    For example, the at least one damping element 11, 12 according to the invention may be disposed in a seat of said vehicle, wherein said non-damped seat portion of a vehicle user may be a seat back portion and said vehicle dampened seat portion may be a seat portion.
    In the safety damper according to the invention, said movable locking element 3 and said counterpart element 4 serve as second fastening means 3, 4. and said safety damped patch portion.
    Figure 3 is a perspective view of a basic safety silencer according to an alternative embodiment of the invention for protecting vehicle users. According to an alternative embodiment of the invention, a safety silencer for protecting vehicle users
    The 20175700 prh 25 -07-2017 comprises at least one damping element 13-16, first securing members 2, a movable locking element 30, counterpart elements 41.42 and a gas spring 5.
    According to an alternative embodiment of the invention, the damping element 13-16 comprises two basic damping threads 13, 16 for twisted coil torsion spring or auxiliary twisted threads 14, 15 for said twisted bore, by means of the first fastening means 2 and respectively from one end of the thread extending from one end of the thread 13-16 to the other 10 seat part of the vehicle operator's non-insulated seat part and of the vehicle user's safety insulated seat part. Said second patch member is different from said first patch member.
    For example, the at least one damping element 13-16 of the invention may be disposed in the seat of said vehicle, wherein said unabsorbed seat portion of the vehicle 15 user may be a seat back portion and said vehicle user seat cushion portion may be a seat portion.
    In the safety damper according to the invention, said movable locking element 30 and said counterparts 41, 42 serve as second fastening means 20 30, 41, 42. The metal wire 13-16 of said damping element of the safety damper according to the invention can be fastened by said threading means 41 42 by means of said second insertion part from said non-insulated insertion part and said safety insulated insertion part.
    In the safety damper according to the invention, said basic damping yarns 13, 16 bent to the helical coil torsion spring, and said auxiliary yarns 14, 15 bent to the helical coil torsion spring are fastened so that said additional wire 14, 15 has a gripping means when said basic damping wire 13, 16 has been unwound to a desired initial distance.
    The safety damping device shown in Figure 3 is in the initial state, wherein said basic damping threads 13, 16 are engaged with said movable locking element 35 30 of said wire end extending from one end of said thread. Similarly, in the basic state, said additional threads 14, 15 are disposed in said counterparts 41, 42.
    20175700 prh 25 -07- 2017 The said gripping structures of said additional yarns 14, 15 do not yet, in their basic state, correspond to the matching elements 41, 42 of said gripping structures.
    When, for example, a vehicle is subjected to a much higher upward acceleration force than the conventional suspension shock due to a mine explosion underneath the vehicle, the safety damper is in the initial state and only the aforementioned basic damping wires 13, 16 are loaded.
    In the safety damping structure according to the invention, said basic damping wires 13, 16 act as plastically deformable elements. The said basic damping yarns 13, 16 are loaded, unlike the torsion spring, which is very similar to these, by pulling the thread in the direction of the wire. The end of the thread at one end of the spool is allowed to be completely free, so that the entire spool can be wound around the fastening member 2. When pulling the yarn, it is twisted off the spool, but with a constant force corresponding to the bending resistance of the yarn that opens from the spool. The plastic deformation of the wire almost completely binds the energy generated by the pulling force and the pulling distance. In this case, it is as if the opposite is performed on the wire 13, 16 as in the case of a coil spring or wire coil. In this case, the wire is provided with a steplessly changing, plastic bending region at the junction of the wires 20 13, 16 and the starting point of the thread. Here, the threaded metal wire 13 straightens out when the maximum bending stress at the bending point exceeds the majority of the material yield point across the cross section. However, the plastic forming margin of the material is not exceeded so that the yarn does not break or break. The degree of deformation is selected by the diameter ratio of the wire 13, 16 and the thread. An equal amount of plastic elongation 25 is caused during the operation of the helical spring, in the case of a straight draw, the deformation is performed only in the opposite direction, one time. The tension level of the modified spot decreases step by step as the already corrected spot slips away from the righting point.
    Fig. 4 is a perspective view of a first damping full-damping safety damper according to an embodiment of the invention for the protection of vehicle users. According to an alternative embodiment of the invention, the safety damper for protecting vehicle users comprises at least one damping element 13-16, first fastening elements 2, a movable locking element 30, counterparts 41,42 and a gas spring 5.
    20175700 prh 25 -07- 2017
    In a safety damper according to an alternative embodiment of the invention, said basic damping wires 13, 16 for the helical coil and the auxiliary wires 14, 15 for the helical coil are provided with at least one or 42, and after the said primary damping wire 13, 16 has been unwound to the desired starting distance.
    In the perspective view of the example shown in Fig. 4, due to an explosion on the drive 10, a higher than normal upward acceleration force has loaded said basic damping yarns 13, 16 of said safety damper such that said desired damping wire 13, 16 has been unwound. Herein, said safety damper is the kitty of the full damping force of the first damping step in the boiling state.
    When said safety damper is in the full damping force engagement mode of the first damping step, said auxiliary wires 14, 15 are disposed in openings in said mating elements 41, 42 such that said gripping structures of said auxiliary wires 14, 15
    In the full damping force engagement mode of the first damping step, said auxiliary wires 14, 15 engage the counterparts of the counterparts 41,42 and develop additional resistance to the dampener. Thus, said basic damping wires 25 13, 16 as well as said auxiliary damping wires 14, 15 are loaded. In the safety damping structure of the invention, said basic damping wires 13, 16 and said auxiliary wires 14, 15 act as plastically deformable elements. Unlike the torsion spring, said basic damping yarns 13, 16 and said auxiliary yarns 14, 15 are loaded by pulling the thread in the direction of the wire. Thanks to the mu30 two-stage construction of the invention, the safety damper is provided with a lighter initial damping step and a more rigid main damping step.

    According to an alternative embodiment of the invention, the movable locking element 30 comprises an attachment point for said metal thread 20 coming out of the thread. Said movable locking element 30 according to the invention is arranged to lock to said at least one counterpart element 41, 42 in such a way that the movement of said movable locking element 30 in the pulling direction of said metal wire coming out of the thread is prevented. Said movable locking element 30 has been locked to said at least one counterpart 41, 42 throughout the first en25 damping phase pull.
    According to an alternative embodiment of the invention, the movable locking element 30 is arranged to move in a direction opposite to the pulling direction of said metal wire coming out of the thread. At the end of the first damping phase draw, during the vehicle air flight, the pull on the safety damper 30 has ceased and said basic damping wires 13, 16 are loosened. Then, the loosened said basic damping wires 13, 16 and the gas spring 5 push the movable locking element 30 in a direction opposite to the pulling direction of said metal wire coming out of the thread, said movable locking element 30 being locked in said at least one locking element 30 in the pulling direction of said metal wire coming out of the thread
    20175700 prh 25 -07- 2017 is blocking. Said movable locking element 30 remains locked to said at least one counter element 41, 42 throughout the first step of damping. Said movable locking element 30 and said at least one counterpart element 41, 42 may be implemented, for example, by means of a locking tongue and ratchet teeth arranged in said locking tongue 5. Said gas spring 5 is normally fully compressed, the gas spring 5 does not move at all during the actual damping stroke. The piston of said gas spring 5 can move moving only if the movable locking element 30 is not loaded with said basic damping wires 13, 16 and said auxiliary wires 14, 15 being pulled out.
    Figure 6 is a perspective view of a second damping activated safety damping device according to an alternative embodiment of the invention for protecting vehicle users. According to an alternative embodiment of the invention, the safety damper for protecting vehicle users comprises at least one damper 15, a first fastening member 2, a movable locking member 30, a counter member 41,42 and a gas spring 5.
    In the safety damper according to the invention, after the first damping step, the pull on the safety damper has ended and said basic damping wires 13, 16 have become loose. Thus, said basic damping wires 13, 16 and the gas spring of the vehicle air flight ai20 have pushed the movable locking member 30 in the opposite direction of pulling of said metal wire coming out of the thread and locked in said at least one locking member 41, 42. outgoing me25 in the direction of pulling of the fine wire.
    In the safety damper according to the invention, said basic damping yarns 13, 16 bent to the helical coil torsion spring, and said auxiliary yarns 14, 15 bent to the helical coil torsion spring are secured so that said additional wire 14, 15 is provided with a gripper when said basic damping wire 13, 16 has been unwound to a desired initial distance.
    The safety damper shown in Fig. 6 is in an activated standby mode of a second damping step, wherein said basic damping wires 13, 16 are engaged by a thread extending from said second end of said thread.
    Correspondingly, when the safety damper is in the initial state, said additional threads 14, 15 are disposed in the openings in said counterparts 41, 42 so that said engaging structures of the said further threads 14, 15 do not yet fall into said latching means. 30 matches.

Thus, said basic damping wires 13, 16 as well as said auxiliary damping wires 14, 15 are loaded. In the safety damping structure of the invention, said basic damping wires 13, 16 and said auxiliary wires 14, 15 act as plastically deformable elements. Unlike the torsion spring, said basic damping yarns 13, 16 and said auxiliary yarns 14, 15 are loaded by pulling the thread in the direction of the wire. Due to the two-stage construction according to the invention, the safety damper also has a lighter initial damping step and a more rigid main damping step 15 in the second damping step.

    Fig. 9 is an exploded view of a safety damper according to an alternative embodiment of the invention for protecting vehicle users. According to an alternative embodiment of the invention, the safety damper for protecting vehicle users comprises at least one actuator 13-16, first securing members 2, 21-23, second securing members 30, 41-44, gas spring 5 and gas spring securing members 52, 53. Said second securing members 30, 41 -44 comprises a movable locking element 30, counterpart elements 41,42 and counter element fastening members 43,44. The parts shown in Fig. 9 and their positioning illustrate, by way of illustration, a working embodiment of the mo20 soft attenuation steps.
    The safety damper structure of the invention may be located in the vehicle seat. By means of the safety damper structure in the seat according to the invention, the seat support system yields, but only at almost the maximum acceleration force that the body can withstand without being injured.
    Due to the safety damping structure of the invention, said force is not significantly dependent on the speed difference between the seat and the cab space, and also remains consistently high for a sufficiently long time so that any motion space under the seat does not run out.
    Thanks to the safety damping structure of the invention, said high damping force ends almost immediately after the critical moment when the structures of the seat and cab have the same speed of movement. In practice, therefore, at the end of a well-tuned acceleration period shortly after the explosion and a second time when the deceleration movements are suitably leveled after falling to the ground. Said same velocity of movement is achieved only at the lowest mass of the seat at the flexural point, which is in the first stage the force of the shock wave
    20175700 prh 25 -07- 2017 Depends on the severity of the fall collision in six and second phase. A strong fall collision, of course, first requires a high explosion shock force that has thrown the protected vehicle at a dangerously high level. Due to the safety damper structure of the invention, the seat 5 support system absorbs almost all of the energy that is transferred from the seat to the seat support structures in the seat down elbow, so that said energy is restored only to return the seat and seat structures to the original seating height.
    Due to the safety damper construction of the invention, the resilient movement of the seat support system begins with a slightly lower force and increases to a maximum after a very short initial period. This is better due to the physiology of the human body, especially the structure and dynamics of the spine. The spine 15, which is spring-loaded and cushioned by the vertebral discs, must be able to settle into a compressed state and be able to gradually build up sufficient body mass before the full damping force is applied. First of all, the masses of the pelvis, thighs, and the large muscles and other tissues attached to them should be firmly pressed against the seat, which is already moving at a lower initial resistance than the maximum. After a suitable al20 deflection distance, the resistor and the resulting acceleration are allowed to rise to the maximum tolerable level by engaging one or more additional damping elements according to the damping movement.
    The solution of the invention provides a more cost-effective and efficient protection of vehicle users from higher than normal acceleration forces caused by explosions or severe collisions.
    It will be obvious to a person skilled in the art that as technology advances, the basic idea of the invention can be implemented in many different ways. The inventions, therefore, are not limited to the examples described above, but may vary within the scope of the claims. Thus, various features may be omitted, modified, or replaced by equivalents, and the features disclosed herein may be combined to form various combinations.
