Hand basket safety seat with side protectionTechnical field
The present invention relates to a kind of child safety seat is and in particular to baby's two-way basket type safety seat.
Background technology
Human civilization and the progress and development of science and technology, make us have the vehicle of various difference purposes, with notOperate in different field with mode and speed.When these vehicle accidents collide, occupant will be in a machineIn tool shock loading environment, in the presence of inertia force with contact force, partes corporis humani's tissue rings producing corresponding biomechanicssShould.Once tissue exceedes can recover the limit, will lead to solve brokenly disorganization or make normal physiological function impaired, decay orLose, that is, cause permanent damage, such as fracture, tendon ligament rapture, Viscera rupture, swollen bleeding of becoming silted up, and cerebral concussion cause intracranialBleeding, faintness, nervous system is obstructed or blocks is lethal dying.For this to vehicle occupant：As spaceman, opportunity of combat driver,F1 equation racing driver, automobile passenger（Including child）Arise at the historic moment etc. emergent safety guard.
The technology of comprehensive existing various safety guards, cuts both ways.These safety guards are in relative velocity areaAlthough interior play certain protective effect, injury to occupant, human body and safety guard structure can not be greatly loweredHuge pressure will be born in part contact position, be to cause tissue to be subject to different degrees of damaging, let us fills to existing safeguard protectionTechnology of putting is analyzed one by one：
1. spaceman safety guard uses technology：When spaceman lift-off and return ground, its acceleration and deceleration are veryGreatly, though subsiding using dorsad stress benzvalene form chaise longue, using honeycomb aluminum, broaching, the energy-absorbing cushion technique such as tube extruding is disappearingConsumption impact energy is to protect spaceman safety, but the variable angle that spaceman produces relative to centrifugal force in running,Make spaceman stress deviate its component of preferable damping, buffering track and still spaceman is produced with impact injury.
2. pilot, F1 equation racing driver's safety guard uses five-point type to fetter technology：Five-point typeConstraint technology is to limit occupant's displacement, prevents from, with vehicle components, direct collision occurs, inertia force is dispersed to driver and crewTwo shoulders, costa sternaless, two thigh hipbones and crotch, increase stress point face, reduce the pressure of unit area.Simultaneously using energy-absorbings such as EPPExpanded material intussusception impact energy, but these technology can only play certain protective effect in relative velocity interval, but headBy five-point type restraint system spacing when still to direction of motion displacement, its head inertia force cervical vertebra tendon ligament will be caused damageWound.When crossing shock peak value, its counteracting force also will bring secondary injury, particularly head back motion impact head to occupantDuring pillow, cerebral concussion can be caused, cause multiple physiology reflections.
3. child safety seat preposition watch box security protection technology：Children's safety preposition watch box technology：This technology usesLarge area stops displacement mode, makes human body impact force action reduce unit pressure in large area cushion pad, head displacement can be madeFor this device cushion pad, playing head cushioning effect and reaching prevents cervical vertebra cervical muscle ligament injury, but this method makes human bodyThorax abdomen stress but unfavorable to internal organs, and because of undirected upper force constraint, lead to human body to be scurried out from preposition watch box fetters and lead to a disaster.Again because of individual variation, head is contacted with preposition watch box and is not ensured that and accurately strike on preferable cushion pad, and head is likely toStrike on preposition watch box skeleton, be likely to result in lisp, cervical spine injury.
4. inflated portable safety guard：Inflated portable safety guard, though there is the foldable advantage of small volumeMaturation not yet developed by its dropped stitch fabric is still that concept technology fails to list always so far.
5. automobile safety protector technology：Existing automobile all to be protected using the technology of inclined type seat belt and air bagShield driver and crew reduce injury when clashing into.This protection device can protect driver and crew's life within the scope of relative velocity,But occupant can not be protected injury-free, when human body inertia force is bound to the limit by seat belt, huge inertia force would potentially result inClavicle, breastbone, shoulder potassium bone fracture, air bag reaching 300Km/h once opening its speed, will produce great impact to head part, though notLethal, but its biological respinse equally can give people to bring different degrees of injury, and such as cerebral concussion causes faintness or even intracranial hemorrhage etc..
Summary existing safety guard technology, its technical characteristic is that restriction personnel's displacement prevents human body and delivery workTool component directly collides, and using padded coaming come apparatus with shock absorbing, plays certain guarantor in certain velocity intervalShield acts on, if outpacing scope, adds individual variation it is impossible to ensure occupant safety.
When vehicle collides, how to make occupant reduce acceleration, that is, reduce effect on human body pressure, can absorbImpulsive force, can pin impact energy again, can prevent personnel's significantly displacement, can play buffering protection function to head, both againThe anti-power of work after impact peak value can be absorbed, the secondary damage to occupant for the counteracting force can be reduced again.Protect occupant to greatest extentSafety, so that occupant is escaped injury is that the manufacturing enterprise of global each universities and colleges, scientific research institution and safety guard facesThe great and problem of complexity.
