Airbag passive safety of vehicles belonging to configure the vehicle when a collision bounce to avoid occurrence of secondary occupants in a vehicle collision or rollover outpaced seat. Only play a role in a crisis situation the configuration, we do not want to use it, but related note you still want to know.
Middle and low car airbag is standard on the two, generally set in the vehicle's driving position and front passenger seat, to take place in the vehicle crashing to protect the front occupants brain and chest.
According to TU HUNG tie rod end note, some of the upscale models, usually equipped with four airbags, in addition to the driving position and the front passenger seat position, the side doors also have two airbags. Some luxury cars have more airbags, such as security known to Volvo's flagship model, the entire vehicle configuration six airbags and 18 curtain airbags, in addition to being inside the front passenger seat, the front and rear doors on each side two airbags, 18 located in the front and rear curtain airbags windshield, side windows at the impact from all directions to provide the most effective protection.
Airbag airbag system is a secondary protection device, which is lined with a special fabric with rubber nylon, bounce when filled with helium harmless. In the event of a collision, the airbag inflator about 0.03 seconds. Very fast inflatable speed passenger's body is to ensure that when the seat belt does not move while the head restraint is still moving forward, the airbag in place in time. Because airbags inflate bounce speed up to 320 km / h, collision if the occupant riding posture, the body will lead to serious injury.
In order to ensure the airbag opened at the appropriate time, automobile manufacturers have provided the airbag detonation conditions, these conditions are met, the airbag will explode. But if it is not safe airbag deployment conditions, the airbag is still not open.
Airbag need to open a certain angle and intensity. Generally, car collision position in front of the vehicle is about 45 degrees right and left side, above 25 kilometers per hour, it may be open airbag.
When automobile collision is part of the main force bumpers and body side member to cushion the impact of collisions, most of the design of the front body collision buffer, and the body stiffness distribution is uneven.
For example, when cars and trucks without rear guard of rear-end accident occurred drill or car rollover accident occurred after the crash barriers, or the occurrence of body side collision, such incidents are often not directly hit the front of the body, mainly the upper body and side collision, the collision body parts of the stiffness is very small, although the cabin has undergone a drastic deformation, resulting in injury or death to vehicle occupants, but due to the collision site does not, sometimes the airbag did not open. Especially in the side impact, if not configured side airbags, main airbag failure to achieve or can not detonate detonation conditions.
At present, many airbags are designed for adults, including the location of the airbag in the car and height. When inflated balloon is faster, it is likely to cause harm to the front of children, it is recommended not to let children under the age of 12 sitting in the front seat, in order to avoid a collision airbags bring serious harm to the child.
Also note that the daily maintenance of the airbag. Mounted on the vehicle dashboard airbag light, under normal circumstances, the ignition switch to the ACC position or the ON position, the warning light will shine around forty-five second self-test, and then goes off. If the warning light stays lit, it indicates that the airbag system is faulty and should be repaired immediately to avoid failure or misuse balloon pop situation.
There Accident statistics show that: "three-point seat belt + airbag" best protective effect, the effective rate of protection up to 60%; Only use seat belts in the case, the effective protection rate of 43% ~ 49%; while using only airbags, effective protection rate declined sharply to 18%. The statistical data on two points: First, the airbag is not a panacea; two is wearing a seat belt is very important.
Now, airbags, ABS (anti-lock braking) and other safety equipment has become standard equipment on most cars. These indispensable safety equipment has also become an important reference factors consumer purchase. But you know, these safety equipment is also very fragile, also need careful maintenance.
Cars with airbags increase the safety factor of course, but you know that airbags have shelf life do? Unlike maintenance airbag body appearance and maintenance as intuitive, easily overlooked, neglected maintenance on the airbag, the airbag is likely to become "invisible killer." To this end, the reporter sought the advice of professionals, teach you gnaw maintenance airbags.
TU HUNG tie rod end, said: In the normal life cycle of a vehicle airbag basic failure does not occur, you can travel from 1 to 20,000 kilometers per post to the 4S shop to check the airbag and its subsidiary parts, but after ten years in the use of the quality of airbags it is difficult to guarantee, must be thoroughly testing conditions, then should be replaced. Master Li Xiaobin said: airbags in the vehicle start 6 seconds indicating to 8 seconds after the light is still flashing or long does not put out, it means that the airbag malfunction; vehicles during operation, the airbag indicator light flashes for 5 seconds after the long bright, also expressed airbag failure, it must be timely to the 4S shop inspection, handling, do not let the airbag become a "killer." |
