Definitions

• the present invention relates to method and spherical seating system protecting passengers in particular from effects of excessive loads in objects impacted by rapid acceleration, thus having high inertia force which negatively impacts these objects.
• Method and spherical seating system protects passengers in particular from effects of excessive loading caused by rapid acceleration, deceleration, change of velocity or other actions of an object under linear movement and enables safe evacuation of passengers of an aircraft in an event of probable catastrophe. Once a predetermined load value is exceeded, the system converts inertia of passengers in linear movement into pressure on seats and heat resulting from friction of the spherical seating system.
• the system can be combined with similar safety devices such as: parachutes, safety belts or airbags for increased safety. Vehicle subjected to impact or any sudden velocity change causes excessive loads generation which negatively effects people and can lead to severe disability and even death.
• the load factor can be significantly reduced by proposed method which is converting impact energy into extended deceleration distance and air resistance.
• Polish patent application No. PL39776520120109 outlines a method of safely dissipating kinetic energy of moving objects exposed to a sudden impact.
• the above mentioned method utilises a device which converts kinetic energy into a mechanical rotor spin (the so called Lqgiewka bumper) and thus decreasing the inertia force acting on vehicle occupants.
• Lqgiewka bumper the so called Lqgiewka bumper
• There are other known options such as use of strengthened construction of car body work and chassis to protect vehicle occupants during impact, especially from back or front impact.
• the energy of an impact is absorbed and load factor decreased by deformable bumper fixing, which is deforming accordingly to the level of resultant impact force generated.
• the devices protecting people from the effect of collision impact includes airbags made from elastomer materials attached to front and/or back bumpers, designed to suit car shape and weight.
• the impact energy is converted into rebound energy which reduces load factor.
• This invention aims to impiement a new method of protective seating system for vehicle and aircraft passengers impacted by excessive loads in events of collisions.
• the essence of the method is based on the division of vehicle occupants compartment into smaller spherical or cylinder-shaped cabins, each accommodating a few crew/passengers.
• the cabins are composed of an 1 inner rotating capsule unit 2, Figure 1 , which is encompassed by an external fixed cabin shell 1 , Figure 1 mounted in the base 3, Figure 1 of a vehicle 4, Figure 1 or a ship.
• the inertia of passengers that subjects them into linear motion due to acting forces, e.g. in car crashes is converted into Fb propulsive force in rotational motion and pressure on seats.
• the torque resulting from the inertia force Fb which acts on arm of X length between the So rotation center and Sc gravity center, Fig.
• the load factor can be reduced thus protecting crew/passengers in emergency situations in aircrafts and spacecrafts by ejecting the inner cabin they sit in in case of emergency.
• the cabin equipped with parachute attached on top and airbags on bottom becomes jolly (boats) as soon as it lands on ground or water Figure 2, Figure 3, Figure 4, Figure 5.
• the capsule, which is mounted to the immovable cabin shell with a catch or a bolt can be catapulted using a bullet hit similar to the ones used in airbags.
• the main principle of the system reduces the effects of harmful loading on crew/passengers by rotation of sperical or cylinder-shaped capsule 2 inside of matching fixed hollow shell 1 , around their rotation center.
• the capsule made of resistant and light materials accommodates seats with safety belts to fasten passengers inside.
• the center of gravity of the rotating capsule 2 with its content is shifted from cabin shell rotation center by X distance perpendicularly to the direction of velocity.
• the torque force Induces rotation of the cabin part 2, together with its passengers inside, towards the fixed part 1 , which becomes a bearing for the first one.
• the device is activated with a special safety lock, e.g. a bolt lock 4, which can be individually adjusted.
• a special safety lock e.g. a bolt lock 4
• the devise is inactive as the acting forces are smaller than designed and set threshold and thus does not affect regular operation.
• FIG. 1 presents an exemplary illustration of the subject of the invention
• Fig.2 presents construction scheme
• Fig.3, Fig.4, Fig.5, Fig.6, Fig.7, Fig.8. presents scheme of installation in an object
• Fig. 9 and Fig. 10 present device installed in a two-person vehicle with a trunk space, respectively, before and after collision, followed by 4 bolt lock release and rotating movement decreasing the load factor.
• Figure 11 shows 4-seat moving part of a cabin
• Figure 12 presents plan view, wherein 5 back rest, 6 seat, 7 headrest, 8 seat belts to fasten passengers.
• Figure 3 shows fixed cabin shell consisting of two elements bolted together 9 with rotating unit inside the bearing 1 with an electromagnetic bolt lock controlled by logic ejection system. This system is designated for aircrafts.
• the fixed cabin shell is mounted with screws to a vehicle
• Fig.14 shows plan view.
• the 2 rotating unit is made of firm carbon or aramid fibers bonded with epoxy resin, which makes them light and
• the fixed cabin shell has a matching openings. It consists of two halves bolted or welded together once the mobile part has been placed inside. The cabin is mounted with screws in the vehicle bearing. The vehicle is steered eiectronically. The 4 bolt is broken after exceeding 20G load factor.
• the method and seating system protecting crew/passengers from effects of excessive loads allows to reduce its effects in horizontal, vertical and diagonal movement. It can be used in aviation and astronautics to reduce the impact of harmful loads on pilots, also in civil aviation, balloons, helicopters, parachutes, in all vehicle and water traffic, cable cars and amusement parks (rol!ercoasters, falling objects or carousels), elevators and cranes as well as in military vehicles to protect users from excessive loading in case of collisions, falls and explosions resulting from failure or other unfortunate random events.
