Description
Technical 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, operate in different field with speed by different way.When these vehicle accidents collide, occupant will be in mechanical impact load's environment, and in the presence of inertia force with contact force, partes corporis humani's tissue will produce corresponding biomechanical response.Once tissue exceedes can recover the limit, to lead to solve brokenly disorganization or make normal physiological function impaired, decay or forfeiture, cause permanent damage, cause intracranial hemorrhage, faintness as fracture, tendon ligament rapture, Viscera rupture, swollen bleeding of becoming silted up, and cerebral concussion, 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.Although these safety guards play certain protective effect in relative velocity interval; but injury to occupant can not be greatly lowered; huge pressure will be born in human body and safety guard component contact position; it is to cause tissue to be subject to different degrees of damaging, let us is analyzed one by one to existing safety guard technology：
1. spaceman safety guard uses technology：When spaceman lift-off and return ground; its acceleration and deceleration are very big; though subsiding using dorsad stress benzvalene form chaise longue, using honeycomb aluminum; broaching; the energy-absorbing cushion techniques such as tube extruding are consuming impact energy 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 type constraint technology is to limit occupant's displacement, prevents and vehicle components occur direct collision, by inertia force be dispersed to driver and crew two take on, costa sternaless, two thigh hipbones and crotch, increase stress point face, reduce the pressure of unit area.Simultaneously using the energy-absorbing expanded material intussusception impact energy such as EPP; but these technology can only play certain protective effect in relative velocity interval; but head by five-point type restraint system spacing when still to direction of motion displacement, its head inertia force cervical vertebra tendon ligament will be caused damage.When crossing shock peak value, its counteracting force also will bring secondary injury to occupant, when particularly headrest is clashed in head back motion, can cause cerebral concussion, cause multiple physiology reflections.
3. child safety seat preposition watch box security protection technology：Children's safety preposition watch box technology：This technology uses large area to stop displacement mode, human body impact force action is made to reduce unit pressure in large area cushion pad, head displacement may act on this device cushion pad, playing head cushioning effect and reaching prevents cervical vertebra cervical muscle ligament injury, but this method makes human body thorax 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 to strike on preposition watch box skeleton, be likely to result in lisp, cervical spine injury.
4. inflated portable safety guard：Inflated portable safety guard, though having its dropped stitch fabric of the foldable advantage of small volume not yet to develop maturation is still that concept technology fails to list always so far.
5. automobile safety protector technology：Existing automobile all to protect driver and crew to reduce injury when clashing into using the technology of inclined type seat belt and air bag.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 in clavicle, breastbone, shoulder potassium bone fracture; air bag reaches 300Km/h once opening its speed, will produce great impact to head part, though not lethal; but its biological respinse equally can give people to bring different degrees of injury, 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 from directly colliding with vehicle components; using padded coaming come apparatus with shock absorbing; certain protective effect is played in certain velocity interval; if outpacing scope; plus individual variation it is impossible to ensure occupant safety.
When vehicle collides; occupant how is made to reduce acceleration; reduce effect on human body pressure; impulsive force can be absorbed; impact energy can be pinned again, personnel's significantly displacement can be prevented, buffering protection function can be played to head again; the 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 the safety of occupant to greatest extent, so that occupant is escaped injury is face great of manufacturing enterprise of global each universities and colleges, scientific research institution and safety guard and the problem of complexity.
