Automatic ejection protection device of automobile seat-China Patent: CN101574937A

The invention relates to an automatic ejection protection device of an automobile seat. A set of ejection slide way is additionally arranged under an original vehicle-mounted seat. By the compression of a spring inside an ejection chamber of the ejection slide way, the vehicle-mounted seat is taken as a seat in a lasting due-out ejection state. An electromagnetic switch of the ejection chamber is turned on by the impacting induction of top position inducers positioned on the front end and the rear end of an automobile body, and the compression spring reacts fast to overthrow the back of the vehicle-mounted seat and eject the vehicle-mounted seat to a proper position of a back seat so as to prevent vehicles from being collided and plunging into a vehicle bottom due to rear-end collision and prevent the deadly bump of body parts of drivers and conductors during vehicle overturning, thereby playing a protection role of a safe seat.

This invention is the same as my plan, in regard of practically; however it is different in alarm system and sensors, mechanical performance of the seat.

Occupant safety system-US Patent:US20110133529A1

An occupant safety system for protecting the occupant of a vehicle seat, the system comprising a movable seat supporting member located under the vehicle seat, the supporting member being operatively connected to the vehicle seat so that the seat moves with the supporting member; and a driving member connected to the supporting member by an elongated linking member; wherein the driving member includes a movable actuator connected to the linking member; wherein the driving member is configured to drive the actuator in a rearward direction causing a corresponding rearward movement of the linking member, wherein movement of the linking member in the rearward direction pulls the supporting member and the vehicle seat in the rearward direction.

The invention is actually a device designed to seat back, it means that designed to reduce driver injury; however, my plan is a separate seat and mechanical process are generally installed in the car room.

Another invention is easy ejector seat with skeletal crash safety Beam-European Patent: EP1325836A2

An arrangement in passenger vehicles, that diverts the impact energy in impacts away from the passengers to the remaining mass of the vehicle thereby protecting the passengers, and in the same arrangement provides utilitarian access to the vehicle, such utilitarian access making it possible to both install multi-element contoured surround seats for passengers and the driver, and also safety devices and arrangements for head-on collision protection that protect the passenger. An indo-skeletal structural arrangement (201,207) proposed for the vehicle, provides further benefits by targeting the strength of the vehicle to protect passengers while minimizing other massive elements in the vehicle.

This invention designed in such a way that reduce the amount of stroke; however in my plan the displacement operation is done through explosive jacks on the rail and wagon attached to a metal plate.

Blast attenuation seat-WIPO: WO2011150501A1

This invention relates to a system and method of armed forces vehicle seating, which reduces the potential for injury to occupants when the vehicle is subjected to a mine or similar explosive device. The seats are ceiling or wall mounted and include a trailing arm, which allows for deflection while providing stability. The seat isolates the occupants from the chassis of the vehicle via a pneumatic or other shock absorber and/or a crushable element to provide protection from vertical and horizontal oriented blasts. These seats can also be combined with shock absorbing/isolating foot rests, appendage (leg) restrain systems and an occupant four-point harness to offer a completely integrated system. This integrated system reduces acceleration/deceleration related injuries, shock injuries to the lower legs, flailing injuries to the lower legs and internal collision injuries. Other options and alternatives are also described.

The above invention is designed for military vehicles in order to reduce the applied pressure to the driver or passenger, which repels strokes through the car's chassis; however, in my plan there is no relation between car's chassis and making safety and all the process occur in car seat.

The last invention is safety seat of Automobile-China Patent: CN103879321A

The invention provides a safety seat of an automobile. The seat is a fixed seat formed by arranging a seat bracket, a seat back rest, a fender bracket, a front seat bracket, a rear seat bracket, a touch dowel bar, a first movable buckle, a second movable buckle, a first spring and a second spring in a layout mode. When the automobile collides with other objects, the touch dowel bar is crashed at the same time and then collides with a contact of the first movable buckle, a buckle head of the first movable buckle is immediately separated from the rear seat bracket for supporting the seat bracket, the rear seat bracket is pulled by the first spring to immediately move backwards, the seat bracket and the seat back rest also immediately incline backwards due to loss of balance, and meanwhile the protective bracket is pulled by the second spring to be immediately buckled downwards. When being buckled downwards, the protective bracket automatically covers the body of a driver, the protective bracket inclines downwards along with loss of the balance of the seat bracket and the seat back rest and drives the driver to lie on his back backwards, the sitting state of the driver is immediately changed, the driver is prevented from being extruded and damaged, and the safety effect is achieved.

This invention does immunization for passenger through embedded belts; however, in my plan there is standard car seat belt only, the main practice of immunization is done through move to back of the seat.

Safe car seat for driver and passenger with capability of return backward via electric explosive jacks, which can be installed and operated in cars. Components of this design include metal plates, explosive jacks, sensors, rails and wagons and shock absorbers , which organize this immune system ; airbag sensors in the front of the car that act with impact pressure and electric-windy explosive jack and two shock absorbers are used to neutralize the force of impact. The tray or metal plate is connected with both jacks, shock absorbers and car seat assembly. It is noteworthy that a tray is installed on the rails and wagons that are attached to the floor of the car from the beginning. This immunization process is applicable to all passenger cars regardless of vehicle type, model and size, and increases the safety factor for vehicle occupants.

In-car immunization to reduce damage and protecting the lives of the passengers of the vehicle security system. Like a warning at high speed or failure to observe safety distance, automatic brake, alert to the driver in case of sleepiness, the airbag, increase the resistance of the car room and encompass various other items. My proposed system design in order to move car front seats. In a way after getting hit to the car through airbag sensors with embedded smart system to identify the direction of pressure applied to the front part of the vehicle. In case of front row passengers, in the event of injury by throwing them to the glass; moreover, seats automatically are driven backwards through explosive jacks so as not to damage the passengers.

The process of securing the passengers in this scheme is as follows, in case of accident for the car, airbag sensors located in the front of the car, operate with the applied impact pressure, these sensors are connected to the secure seat sensor; thus, the front row seats of the car are thrown back via pressure force of explosive jacks about twenty centimeters and in the rear and center of the car room guide, which is the safest part for passengers. This mechanism is done through two electric-windy explosive jacks and two shock-absorbers in order to neutralize the force resulting from the collision and overthrow of the vehicle. Explosive jacks are kind of jack that in form of electric and windy jacks, then are commanded through the sensor and releases the compressed wind force in the cylinder jack.

The task of shock-absorber in this system is to pressure control to the seat and driver, which is operate through two tiny shock-absorbers. Displacement of the seat is done on a tray that is actually kind of a metal plate and it is embedded under car seat. Both jacks and shock-absorbers are connected to the tray. In another word, the whole set of driver's seats is on this metal plate; as a result, the seat is capable of all car facilities such as massage, hot and cool situation freely.

The process of making this device is as follow, first of all the tray of seat bottom is constructed proportionate with dimensions of car seat then install the tray on rails and wagons, which are already screwed to the floor of the car room. The second stage is about installation of explosive jacks to the tray, at this stage first jack is screwed in front of the tray. The command of this jack is sent by the sensor, which is in front of the car, this sensor is actually the same used sensor in car so as to the airbag function is inside the steering.

The next stage is about second jack will be screwed at the apex of the angle 90 degree of tray, this angle is used for diagonal movement of seat, in case of existing hit to the pillar or door of the car. The sensor of this jack is also taken from airbag Steering Sensor at pillar of the car. Ultimately installation of shock absorbers are mounted to the back of the tray. Here the springs are mounted at the beginning and end of the tray in such a way that shock absorber head to the tray and its end is screwed to the end of the wagon. This designed seat in addition to saving the lives of drivers and passengers, supplies all facilities and features of a standard seat for comfort of car passenger.
