Car Accident Information Center
     By 2006, there were an estimated 177 million airbag-equipped vehicles on the  road. Because of the sheer number of these devices, the increased frequency of  airbag failures that cause injuries shouldn’t be shock to anyone. Airbags and  seatbelts are components of a passive restraint systemdesigned to be used in tandem. Even  when seat belts are used, airbag accidents continue to occur. Since 1987, the  National Highway Traffic Safety Administration ("NHTSA") reports that  22,466 lives have been saved by airbags. Yet, the NHTSA reports that since  1990, 284 airbag-related deaths have occurred.
       
       Airbag  Design 
As airbag accidents and injuries have increased, the NHTSA has responded by  requiring automobile manufacturers to install "smart" airbags, which  were designed to reduce airbag injuries, accidents, and deaths by automatically  adapting to a variety of occupant sizes and positions, as well as to variable  auto speeds and crash angles. However, even after these standards were  implemented, airbag failures related to design and manufacture, still are  responsible for injuries and deaths.
     Inadequate Airbag  Safety Standards 
       When an accident occurs, a vehicle typically goes through a sudden  deceleration. Airbags are designed to prevent riders from plunging forward,  hitting the vehicle interior, and suffering injuries. To make airbags safer,  the NHTSA has issued enhanced regulations to prevent airbag injuries and  accidents; however, these regulations do not require manufacturers to use  specific designs, but instead only mandate that broad safety standards are met.  So even when a vehicle manufacturer has complied with the new safety standards,  it’s still possible to make legal claims against auto manufacturers and others  for injuries and accidents resulting from airbag design or manufacturing flaws,  mistakes in installation, and inadequate warnings.
       
       Motorists need to be aware that the airbag in their current vehicle may not  offer the latest and safest technology. Depending on the year a vehicle was  produced will determine how compliant a particular air bag design is with the  most up-to-date federal safety standards. Specific designs have been shown to  cause airbag accidents and injuries.
       
  Airbags that  Fail to Deploy
       Airbags are some of the most complicated safety equipment on the market  today. With over 177 million now in use nationwide, defects are bound to cause  injuries. According to the most recent research, more people are injured or  killed in accidents where the airbag fails to deploy properly than in accidents  where the airbag deploys and injures the occupants.  In an exhaustive study in 2007 by the Kansas  City Star newspaper reported that over four times as many people in a six-year  period suffered injuries or deaths by the airbag’s failure to deploy as from faulty  deployment. The defect behind the failure to deploy can result from faulty  airbag parts, poor installation, and inadequate design. In addition, airbags  are not a complete solution; even when they do deploy as designed, thousands of  people are still injured and killed.
   
  Changes in  Airbag Design due to Injuries
       Manufacturers continue to refine current technology and develop new ways to  use them to enhance safety. There are some common types of airbags in use:
     
     The very first airbags were located in front of the  driver, inside the hub of the steering wheel and called frontal airbags. Later,  more were added behind the dashboard across from the front-seat passenger. In  1998, NHTSA required all passenger cars (and with the 1999 model year all SUVs,  pick-ups and vans) to be equipped with frontal airbags. By 2007 all light  vehicles were required to have advanced frontal airbags. Advanced designs were  able to measure factors—such as weight and position of the occupant—to prevent  airbag accidents and injuries. However, because the NHTSA requires only that certain  general safety standards be met, vehicle manufacturers are free to offer  airbags of varying design as long as they meet the minimum safety standards;  thus, not all airbags operate the same way.
     
     Auto companies also offer optional side and roof  airbags, as well as side-curtain airbags. Unlike frontal airbags, which are not  designed to protect from injuries in rollovers, rear-end collisions, or side  impact crashes, side airbags are often designed to offer additional protection  from injuries for such accidents. However, these airbags, too, can cause  injuries for some of the same reasons discussed above.
     
     Side airbags are usually of three types: those that  protect the head, the chest, or the head and chest. Side airbags which are supposed to protect primarily the  head from injuries are most often mounted in the roof rail above the side  windows and will deploy in a serious side-impact crash. They offer protection  as a curtain. The curtain is generally meant to help protect rear and front  occupants in a rollover accident. Side airbags, designed primarily to protect  adult passengers' chests, are mounted inside a seat or in a door. Those  designed primarily to protect an adult's head and chest from injuries in airbag  accidents are usually mounted on the side of a seat and are generally larger  than a chest-only side airbag design.
          
         Causes of Airbag  Injuries
       Airbags are designed to adjust to the size, weight, and position of the  occupant, and to the position of the seat. Injuries usually take place when the  airbag doesn’t perform according to its design specifications, deploying late,  too early, or not adjusting properly. Because they deploy at speeds as high as 200  mph, they possess a significant amount of potential for injury. If an airbag  deploys too early or too late it can result in head, neck, facial injuries and  broken bones. If the occupant comes into contact with an airbag that is still  inflating, it is traveling at up to 200 mph when it hits, which can cause brain  injuries, abrasions, broken bones and more. If the occupant is thrown into a  bag that is already deflating, that occupant may hit the vehicle's interior,  causing injury or death, instead of the fully inflated airbag.
       
       Various factors affect deployment of advanced airbag systems (installed in  all 2006 and later models), which can create the risk of airbag accidents  resulting from system failures or airbag defects. Some of these factors  include:
     
       
         - Seat position. The       position of the seat can affect how soon, or late, a person comes into       contact with the airbag. Sensors are designed to adjust the speed of the       deployment to match the seat's position. If the sensors doesn’t operate       properly or if not enough sensors are installed, airbag injuries can be       severe. 
 
       
       
         - Occupant position and weight. Where a       person sits, whether middle, the side, or leaning forward, and how much a       person weighs, also affects when and how the occupant will come into       contact with the airbag. Sensors typically will adjust for these       circumstances, but indicators are not foolproof. For instance, a lighter       person holding a bag of groceries could give the sensor false information       about the occupants' forward-moving velocity. 
 
       
       
         - Sensor failure. Sensors may       also detect and make adjustments for the speed at which the vehicle is       traveling, the angle of the crash, the speed at which the vehicle       decelerates, and whether the occupant is wearing a seat belt. Not wearing       a seat belt could cause the occupant to move forward too quickly during       the initial deceleration and end up on top of the still inflating airbag,       which could lead to death or serious injury. Airbag injuries and deaths       can result from inadequate system designs, incomplete or hard-to-find       warnings from the manufacturer, or failing sensors. 
 
       
       
         - Module design. The shape       and size of the opening of the airbag module can affect deployment, and       because the NHTSA only mandates general standards, specific design       features are up to individual manufacturers. The manufacturer's choice of       design could lead to unnecessary airbag accidents and injuries. 
 
       
       
         - Inflation and tethering volume. How the       airbag is tethered affects how far into the interior of the car it deploys       (this distance is also known as the airbag's excursion). The tethering and       the inflated volume of the airbags, which can vary by manufacturer, may       affect whether an occupant is injured during an airbag accident. Airbag       accidents and airbag injuries may be the result of systems that do not       take account different types of occupants or occupants' positions (because       of design or parts failure, for example) or may be the result of a       manufacturer not giving proper warning about potential systems failure. 
 
       
       
         - Airbag storing. How the       airbag is folded will affect deployment speeds and force during an accident.       Injuries can be caused by how an airbag is, or is not folded. 
 
       
       
         - Airbag material. The       material used to construct an airbag can affect whether or how an occupant       is injured by striking the airbag. Lighter material is better. Serious injuries       can be prevented by using appropriate material. 
 
       
       
         - Angle of deployment during an accident. Airbag       injuries can be affected by the angle of deployment, with more vertical       deployments often being better than horizontal. Also important is whether       the airbag has lateral-bias flaps, which could direct an airbag to the       side if it strikes someone during inflation. For drivers, the angle of the       steering wheel can direct an airbag higher or lower on a driver's body.       Keeping the airbag away from the head and neck is usually better. 
 
       
       
         - Airbag deployment speed. The speed       at which airbags deploy, which will be different for people weighing       differently or for the position of the seat, can affect whether someone is       injured. Design flaws, improper inflation, faulty information about the       occupants or their seat position can all be causes of airbag accidents,       injuries or death. 
 
       
       
         - Threshold triggers of airbag deployment. Each       airbag system is designed to deploy when reaching designated trigger       thresholds. These thresholds along with the speed and force of their       deployment vary greatly from manufacturer to manufacturer. If these       systems do not work correctly or if they were not designed properly, the       risk of death and injury is from an airbag malfunction is magnified. 
 
       
       
         - Airbag venting. All       airbags vent after deployment. How they do this might determine whether an       individual strikes a fully inflated airbag or not. This element       is critical to an occupants safety and could lead to an injury because of       poor design or an airbag defect. 
 
       
       
         - Design of sensor. In order       to detect as many variables as possible, some sensors use optical,       infrared or electric fields to better gauge airbag deployment. However,       the number and type of sensors used by a vehicle manufacturer are       different (even across different models) and could also be a determining       factor in when and how an airbag is deployed. Airbag defects from       inadequate or poorly designed sensor systems can result in serious injury. 
 
       
       
         - Design limitations. Sometimes airbags       don’t prevent injuries in certain accidents, such as when a vehicle hits a       tree, when a car goes under a truck, or in certain head-on collisions       where the deceleration might not be sudden enough to trigger deployment.       Also, airbags might not be as effective in side impacts, in rollovers, or       in rear-end collisions. In these cases, inadequate design, insufficient       warnings, or ineffective  equipment       can lead to accidents as well as to airbag injuries and deaths.

     Defective Airbag  Injury Attorney
          
       When  someone suffers an injury in a motor vehicle accident and defective airbags are  suspected, a qualified legal expert in airbag operation and investigation  should be consulted. This area of personal injury law is complex because  negligence in design, manufacture, and installation of airbag must be  investigated, documented, and proven in court in order to collect financial  compensation. An expert personal injury attorney experienced in vehicle crash  investigations can protect an injured person’s rights to recover financial  compensation for their injuries. In cases where someone has died of their  injuries, immediate relatives may be eligible to recover damages and financial  compensation, depending on the state the accident occurred in, their  relationship to the deceased, and the length of time that has passed since the  death occurred. In all of these cases, a legal expert should be consulted.
