Background technology
At present, different safety air bags generally adopts with a producer, and at identical temperature or condition of different temperatures, pressure range is large, causes airbag undercapacity in initiation process and the problem that causes the difficulty of matching of to tear etc. high.In addition; in NCAP star rating experiment; 64kph is biased experiment needs to possess high pressure in airbag to protect occupant, and the air bag that this pressure is high is sometimes be unfavorable for protecting occupant under 50kph head-on crash condition, brings both contradictions to mate the high problem of balance difficulty in this case.Have again, the exploitation of parts intensity is in order to ensure that each parts detonate experiment and situation about not losing efficacy at different temperatures, wish that airbag internal pressure is lower, and the optimization that this 50kph or 64kph is biased experiment air bag needs high pressure, the contradiction that both produce also can bring air bag to develop the high problem of difficulty of matching.Generally, solving this problem is realized by adjustment airbag contour structures or adjustment gas generator, but its setting range is limited, and the cycle is long, and the difficulty of matching optimization is large, costly.
Summary of the invention
The present invention is the problems referred to above that will solve prior art existence, provides a kind of adjustable pellosil structure deflation hole airbag apparatus.Its air bag structure is simple, and under hot conditions, normal temperature condition and the cryogenic conditions that can detonate with air bag, the difference embodied by pressure, carries out size adjustment to pellosil structure deflation hole.Also can be biased according to 50kph with 64kph the adjustment that the different vehicle collision type of experiment carries out airbag internal pressure, reach protected effect and the object of both balances.
A kind of adjustable pellosil structure deflation hole airbag apparatus, comprise surface and have one with the airbag main leaf of auxiliary exhaust ports, airbag main leaf is connected with pellosil deflation hole pad, with adjustable main exhaust hole on pellosil deflation hole pad, described main exhaust hole is corresponding with auxiliary exhaust hole site and main exhaust bore dia is less than auxiliary exhaust bore dia, described pellosil deflation hole pad is made up of cloth matter pad and pellosil attached to it, both are equipped with deflation hole and deflation hole on pellosil is main exhaust hole, the diameter of the deflation hole on cloth matter pad is consistent with the diameter of auxiliary exhaust ports.
Described pellosil deflation hole pad to be connected on airbag main leaf by sewing or by silica gel heat and mode be connected on airbag main leaf.
The invention has the beneficial effects as follows: structure is simple, and mutually compatible with current air bag system, it is on current safety air bag architecture basics, place by airbag deflation hole place the adjustment that pellosil deflation hole pad is exhausted hole size.The condition of different temperatures of detonating with air bag can be realized, such as high temperature, normal temperature or low temperature condition, with the pressure gap of condition of different temperatures in airbag, different to the impulsive force of deflation hole place pellosil, realize the adjustment of pellosil deflation hole size, namely airbag internal pressure is larger, it is larger that pellosil deflation hole size increases, pressure is less, pellosil deflation hole size increases less, improve airbag parts intensity like this, reduce the relevant difficulty of its exploitation, particularly be suitable for the experiment condition that high temperature detonates, adjustable in the case pellosil vent structure is by under the effect of large pressure, produce large deflation hole size, improve the air leakage amount of airbag, reduce the gentle pressure separated airbag and bear, thus realize the integraty of airbag parts intensity.On the other hand, there is 50kph head-on crash and 64kph offset collision in the experimental project of NCAP star test evaluation simultaneously, in the experiment of 64kph offset collision, the air bag igniting time will be later than the 50kph head-on crash experiment safety air bag ignition time, some vehicles in order to obtain set protected effect in the experiment of 64kph offset collision, need in airbag, to possess high pressure protect occupant, and the air bag optimization under 50kph crash type does not need too high pressure, like this in order to balance both experimental results all had, possesses the adjustable row pore of pellosil structure, by optimizing its initial exhaust hole size, realize the passenger protection that 50kph and 64kph is biased experiment simultaneously, reduce development difficulty.This structure can solve parts exploitation and air bag to passenger protection contradiction that effect optimization brings, such as consider from the angle of protected effect, sometimes wish that airbag volume is smaller, there are enough pressure protect occupants like this, but from the angle of parts intensity exploitation, the structure that airbag volume is little, when detonating under the high temperature conditions, easily cause the situation of airbag fracture failure, in this case, the adjustable row pore airbag apparatus of pellosil structure, by the design of deflation hole, the optimization to passenger protection effect can be realized, also deflation hole is increased by increasing with pressure under hot conditions the situation accelerating to be vented, avoid the problem that airbag lost efficacy.
Adjustable pellosil structure deflation hole airbag apparatus, because default deflation hole size is little, even if when point of ignition is more late, also can before realizing the protection to dummy, keep storing enough pressure in airbag, deal with when 64kph biased experiment dummy contacts airbag, can realize its protection, and with the continuous intrusion of dummy relative to airbag, also there is the process thereupon improved in airbag internal pressure, thus drive pellosil structure deflation hole size to increase, carry out many free air capacities in adjustment airbag to discharge, and reach the highest along with bag internal pressure, then pellosil structure deflation hole reaches maximum, then with the reduction of pressure, now adjustable pellosil structure deflation hole size starts to adjust to undersized direction, thus different bag internal pressures is provided, realize carrying out actv. protection to the occupant of different crash type.

Detailed description of the invention
As Fig. 1, the present invention includes surface and have one with the airbag main leaf 1 of auxiliary exhaust ports 101, airbag main leaf 1 makes (or silica gel heat mode) by sewing thread 3 and is connected with pellosil deflation hole pad 2, pellosil deflation hole pad 2 is placed on airbag main leaf 1 inside (also can be placed on airbag main leaf 1 outside), with adjustable main exhaust hole 201 on pellosil deflation hole pad 2, described main exhaust hole 201 is corresponding with auxiliary exhaust ports 101 position and main exhaust hole 201 diameter is less than auxiliary exhaust ports 101 diameter.
As shown in Figures 2 and 3, described pellosil deflation hole pad 2 is made up of cloth matter pad 202 and pellosil 203 attached to it; Both are equipped with deflation hole and deflation hole on pellosil 203 is main exhaust hole 201, and the diameter of the deflation hole 204 on cloth matter pad 202 is consistent with the diameter of auxiliary exhaust ports 101.
When vehicle be in collide in different temperatures environment time, the gas generator 4 be arranged on airbag main leaf 1 is detonated, producer produce gas enter airbag.Under low temperature and normal temperature condition, the size variation amplitude in main exhaust hole 201 is little, and under the high temperature conditions, the high pressure that main exhaust hole 201 produces owing to being subject to producer, there is tensile deformation and main exhaust hole 201 size increased in the pellosil material around main exhaust hole 201, but be reduced to final disappearance gradually with pressure, main exhaust hole 201 can return to original size size again, by the mode of this adjustable deflation hole size, reduce the impact of high pressure to airbag intensity, thus ensure the integraty of airbag design of part.
When vehicle collides in different crash type, the gas generator 4 be arranged on airbag main leaf 1 is ignited by the firing command that safety air bag controls ECU, and the gas that producer produces enters airbag.Under 64kph Frontal offset impact, point of ignition is more late than 50kph head-on crash point of ignition, but because pellosil adjustable row pore 2 structure is little in initial condition deflation hole 201 size, more gas can be stored in airbag, improve airbag internal pressure, and along with occupant is to the increase of the impact energy of airbag, pellosil deflation hole 201 produces tensile deformation with the increase of airbag internal pressure, corresponding size also can increase, suitably airbag internal pressure is discharged, the injury that pressure high in airbag causes occupant can be avoided, also can realize can not causing later stage hypotony because of losing heart too fast in bag, the situation causing occupant's head or chest to touch instrument carrier panel or bearing circle to damage, thus the effect improved passenger protection.
