Abstract
The invention relates to the field of automobile safety and particularly relates to a headrest safety airbag. The headrest safety airbag is arranged in a headrest of an automobile seat and is used for protecting a head and a neck of a passenger in an automobile. Compared with an existing whiplash protection system WHIPS and a driving type headrest, all parameters of the headrest safety airbag provided by the invention are more easily controlled, and the limitation on geometric dimensions in a designing process is less.
Description
Technical field
The present invention relates to field of automobile safety, particularly to one headrest air bag.
Background technology
Incidence damaged is modal injury in vehicle accident.Just in Sweden, 2.5 ten thousand people are just had to suffer this kind of injury every year.The ratio of permanent whiplash effect evil accounts for 1/10th of the wounded sum.When a vehicle is in a collision, the health of occupant and head, with the support of seat and headrest, can be protected.But at this time cervical region does not support, thus very big pressure will be born, to neck injuries.Incidence protection system can when colliding, meeting crumple suitably backward of resting the head on, and the suitable hypsokinesis of seat simultaneously so reduces the impact that cervical region is brought by collision, thus preventing the vertebra of occupant from pulling backward, getting rid of and knocking steering wheel before also preventing the head of occupant.
The incidence protection system WHIPS of Volvo is a kind of protection system being integrated in front chair, it is possible to support whole back and the head of occupant in rear end collision.This protection system by the energy absorption deformation component between backrest and medicated cushion thus collision is cushioned.And when there is rear impact, backrest also can follow the backward moving of occupant, to reduce the stress of cervical region and spinal column.Incidence protection system has obviously protective effect, the research according to Volvo Cars vehicle accident research group, and the long-term impact that incidence can be damaged by this system reduces half.
Existing incidence protection system mainly adopts upspring type headrest or slowdown type backrest, SAHR (Pro-ActiveHeadRestraint) such as Japan, it is at a seat machinery arranged below and a tubular frame and pressure plare, most Hou is connected to a rotating shaft, whole system is linked to the position close to seat bottom, and the path system of tubular frame controls with the transverse axis conduit on one group of seat top, when vehicle bears unexpected shock, driver's health thus when pressing backward, conduit can be forced to rise and make headrest turn forward, propping up head prevents head from quickly swinging back, the safety of protection head cervical vertebra.
The application for a patent for invention that publication number is CN104379411A discloses a kind of vehicle occupant protection system including air bag, and this air bag is received within the backrest of seat and in deployed condition to extend between two seats of vehicle in folded state.Air bag has regio pectoris and Head Section, and described regio pectoris covers the chest of automotive occupant and described Head Section and covers the head of automotive occupant in side in side.
Summary of the invention
The present invention proposes a kind of headrest air bag being different from prior art, and compared with prior art, the rest the head on parameters of air bag of the present invention is easier to control, and the physical dimension restriction when design is less.
In view of this, the present invention provides a kind of headrest air bag, and described headrest air bag is arranged in the headrest of automotive seat, for protecting the incidence of passenger.
As can be seen here, comparing incidence protection system WHIPS and SAHR, the headrest air bag parameters of the present invention is easier to control, and the physical dimension restriction when design is less.

Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, the present invention is described in more detail by the following examples, but protection scope of the present invention is not limited to described embodiment.
As shown in Figure 1-2, the present invention is integrated security air bag in traditional common chair headrest, such that it is able to reduce the distance between occupant's head and headrest by triggering air bag when touching after occurring, and provide soft support to reduce or to avoid incidence to come to harm for head.
Wherein, Fig. 1 is the state before headrest air bag triggers；Fig. 2 is the state after headrest air bag triggers.During headrest air bag igniting, the chemical reaction of all fiercenesses completes in the gas generator of metal.By the airbag of air bag is adjusted folding mode, it is possible to make airbag face upward or downward (i.e. car load Z-direction) along resting the head near the one side of occupant's head inflating expanded, be the incidence of occupant will not be caused any harm in this case.And, there is again very strict requirement the duration of ignition by headrest air bag, it is necessary to just touch head when air bag is full of, and now the airbag of air bag launches process and has finished on, and causes any harm without to the incidence of occupant.
When touching after carrying out Whiplash test or real vehicle; the spacing of chair headrest and occupant's head is it is generally required in certain scope; because the head that so can allow occupant contacts within the extremely short time with headrest, thus provide support for head, cervical region, protect occupant.But due to chair headrest is too small with the spacing of occupant's head, the comfortableness of seat and headrest can be affected again.If increasing headrest air bag, because the spacing in collision process between airbag aeration meeting rapid drop occupant's head and headrest, so when adopting the headrest air bag of the present invention, spacing between occupant's head and headrest can suitably be amplified, so can improve the riding comfort of occupant, therefore the size at fore-and-aft direction (car load X to) of resting the head on also can suitably reduce, it is seen that the physical dimension restriction when design of the headrest air bag of the present invention is less.
SAHR (Pro-ActiveHeadRestraint) generally can increase relatively multisensor and structure in chair headrest and backrest, and this can make the internal structure of chair headrest and backrest more complicated.If using the headrest air bag of the present invention, single headrest air bag module is directly arranged in chair headrest, backrest only need to arrange air bag ignition line, the chair headrest of the visible present invention compares SAHR with the structure of backrest can be simply a lot, and the parameters of headrest air bag is compared SAHR and is easier to control.
The present invention relates to field of automobile safety, particularly to one headrest air bag, described headrest air bag is arranged in the headrest of automotive seat, for protecting the incidence of passenger.Comparing existing incidence protection system WHIPS and SAHR, the headrest air bag parameters of the present invention is easier to control, and the physical dimension restriction when design is less.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
