Description
Technical field
The utility model relates to technical field of vehicle safety, and in particular to a kind of safety chair seats of car.
Background technique
Seat is the important safety component of automobile, supports the weight of occupant, mitigates impact and vibration that decaying is transmitted by vehicle body
It is dynamic, to provide comfortable seating condition for occupant.With the development of the automobile industry, the function of seat is not only and provides to multiply
The comfort of seat should also have the defencive function when accident occurs for vehicle to occupant.With the universal and automobile of highway
The raising of speed, during car steering because caused by head-on crash pernicious traffic accident it is increasingly severe, occur in automobile acute
When strong frontal impact, it is based on effect of inertia, driver often turns forward because of the effect of strong inertia force, engine and turns
It hits and moves backward to transmission tube major gene, the chest of human body excitation collision can occur with steering wheel and cause casualties.It is existing
Have in technology, in order to avoid above-mentioned injury caused by car crass, the anti-wound of shrinkable is applied usually in automobile steering system
Transmission tubing string is turned to, however, finding according to statistics of traffic accidents data and to the analysis of vehicle impact testing result, automobile front
When collision, steering wheel is still the main element for making driver's injury.
Chinese document CN204055446U discloses a kind of turnable safety seat, including for vehicle floor be connected
It is articulated on pedestal at pedestal and the seat body on pedestal, seat and backrest link position by shaft, pedestal and chair
It is equipped with telescoping cylinder for overturn seat body around the shaft between seat, the articulated position of seat body and pedestal is equipped with use
In the locking structure that seat body is locked to upturned position, lockable mechanism is ratchet structure, is additionally provided with and is used in seat body
Seat body is set to be returned to the resetting-mechanism of normal condition from rollover states.Although the safety seat is in overturning control system measurement
There are driving telescoping cylinder to push turnover seat when the risk of collision, it is in driver and faces upward state in advance, reduce car accident pair
The injury of driver, but there is also following disadvantages for the overturning safety seat, the both legs of driver are still within seat after overturning
The area of space of chair and headstock, when head-on crash occurs for vehicle, if biggish deformation has occurred in driver area, it is easy to hurt
Evil arrives the both legs of driver, such as blocks the both legs of driver, and driver is made to be not easy to escape.
Chinese document CN106828222A discloses a kind of safety chair seats of car and its control method, comprising: seat, layback
Motor, seat support, translation motor, gear, rack gear, rear limited block, front limited block, vehicle body acceleration sensor, with location hole
Guide rail, abutment sleeve, release lever, magnet, electromagnetic coil, drag-line, holddown spring and microprocessor；Wherein, seat bottom connects
Layback motor is connect, motor lower end connecting chair bracket of swinging back, seat support is fixed on vehicle body, and seat support is far from steering wheel
One end connect translation motor, translation motor periphery is at round and be equipped with around the circle spacing gear of outwardly convex, gear pressure
It closes on rack gear, rack gear is equipped with rear limited block far from steering wheel one end, is equipped with front limited block, seat support close to steering wheel one end
The other end is pressed on the guide rail with several location holes, and holddown spring and drag-line are terminated on abutment sleeve, and abutment sleeve lower end is inserted
Enter to realize the positioning of seat support in a positioning hole of guide rail, the upper end of one end connecting positioning sleeve cylinder of drag-line, drag-line it is another
One end connects release lever by a pulley, and magnet is mounted on release lever, is equipped with electromagnetic coil, micro process right above magnet
Device is separately connected with vehicle body acceleration sensor, electromagnetic coil, translation motor, layback motor.The safety seat can be touched in automobile
Moving backward and swinging back for seat is automatically controlled when hitting, and on the one hand can be increased driver at a distance from steering wheel, be made driver
From bearing passive shock when steering wheel moves back；On the other hand, seat layback can effectively reduce a part inertia force forward,
Reduce the risk of driver's active crash direction disk and front foreign matter.But the safety seat structure is complex, uses two
Motor controls the layback of seat respectively and moves back, higher cost, and the safety seat lacks damping performance, influences using comfortable
Property.
Chinese document CN201970884U discloses a kind of seat that can be adjusted in collision, including chair angle is adjusted
Switch, seat, chair angle regulating switch connecting chair further include crash sensor, data processor, gas generator, touch
Sensor connection data processor is hit, data processor connects gas generator, and gas generator connecting chair angular adjustment is opened
It closes, gas generator is also connected with seat.Crash sensor send collision alarm to data processor, and data processor sends out gas
Raw device release gas kinetic energy pushes chair angle regulating switch to open, while seat being pushed to tilt backwards, i.e. seat and the chair back is same
When tilt backwards, so that thigh has been upsweep, upper trunk hypsokinesis.Thigh has upsweep, it is possible to reduce occupant's shank connects with instrument board
Touching, to reduce injury to shank, upper trunk hypsokinesis can injury to avoid the biggish binding force of safety belt to chest, reduce
To breast compressions amount.But rear-inclined limited extent of the seat when automobile collides, and the seat lacks damping energy-absorbing
Effect, occupant safety can not be protected when colliding to greatest extent.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of safety chair seats of car, and manufacturing cost is low, structure
Simply, damping, buffering performance is good, and can generate layback movement simultaneously when chair tilting when automobile collides but also generate
Shifting movement is afterwards preferably to ensure occupant safety.
In order to achieve the above objectives, the utility model is achieved through the following technical solutions:
A kind of safety chair seats of car, including seat body, support guide plate, hypsokinesis motor, swing rod and locking balance element, institute
