Airbags: Mandatory Safety Features And Their History

Airbags have been a standard feature in cars for decades, but they weren't always legally mandated. In 1991, Congress passed a law requiring automakers to install airbags on both sides of the front seats of their vehicles. However, this law only went into effect in 1998, giving car manufacturers time to convert their factories. Since then, airbags have become an essential safety feature in vehicles, providing crucial cushioning for occupants during collisions. While airbags were once a point of contention, with some experts questioning their effectiveness, they are now credited with saving thousands of lives and reducing the risk of death in car crashes.

The Intermodal Surface Transportation Efficiency Act of 1991

One of the chief goals of ISTEA was to develop a "National Intermodal Transportation System" that was economically efficient and environmentally sound. This represented a new approach, as the focus shifted from just highway transportation to intermodalism—the seamless linking of highway, rail, air, and marine transportation. The act included provisions aimed at breaking down the barriers that had long separated different modes of transportation in both legislation and practice.

ISTEA brought about thousands of changes, some of which were significant enough to be considered a sea change in the transportation sector. The act introduced buzzwords like "flexibility," "innovation," "involvement," and "collaboration" to the transportation planning and development process. It transformed the relationship between the federal government and state and local governments when it came to funding transportation projects.

The $155 billion act authorized federal highway funding for fiscal years 1992 through 1997 and restructured the Federal-Aid Highway Program, the primary vehicle for states and localities to obtain funding for projects. ISTEA gave state and local governments greater flexibility in determining transportation solutions and made money available for new types of programs. These included projects to mitigate traffic congestion, enhance safety, and improve air quality.

The act also opened up the transportation planning process to more public involvement than ever before, bringing new players to the table and increasing collaboration. One notable example of this increased collaboration was the creation of the Congestion Mitigation and Air Quality Improvement Program (CMAQ). CMAQ directed federal funds towards transportation projects that helped state and local governments improve air quality, marking a shift from the traditional funding goals of mobility and safety.

ISTEA also funded a range of special programs, including those aimed at increasing the use of safety belts and motorcycle helmets, developing state scenic byways and recreational trails programs, and conducting research and development to address highway issues. The act provided more money for states and brought about a huge change in programs and program eligibilities.

In addition to its impact on transportation planning and funding, ISTEA also had a mandate regarding automobile safety. The act required that passenger automobiles and light trucks built after September 1, 1998, be equipped with airbags as standard for both the driver and the front-seat passenger. This was a significant development in automotive safety, building on earlier efforts to improve safety through the use of seat belts.

Airbags became mandatory in 1998

It wasn't until the publication of Ralph Nader's book "Unsafe at Any Speed" in 1965 that the concept of airbags gained traction. Nader speculated that the combined use of airbags and seat belts could prevent thousands of deaths in car accidents. This prompted Congress to pass the National Traffic and Motor Vehicle Act in 1966, which required automakers to install seat belts in all vehicles. However, seat belt usage remained low, with only about 25% of drivers buckling up.

In the 1970s, Ford and General Motors began installing airbags in some vehicles, but their effectiveness was questioned. A 1973 study suggested that three-point seat belts were more effective and less risky than airbags. During this time, airbags caused some fatalities and were found to be particularly dangerous for children and individuals of smaller stature. Despite these concerns, automakers continued to refine airbag technology, and by the late 1980s and early 1990s, airbags were becoming a common feature in many vehicles.

In 1991, Congress passed the Intermodal Surface Transportation Efficiency Act, which required the installation of front and side airbags in all cars and light trucks sold in the United States. This law went into effect on September 1, 1998, giving automakers seven years to prepare and make the necessary adjustments to their manufacturing processes.

Since airbags became mandatory, they have been credited with saving tens of thousands of lives. Researchers estimate that airbags reduce the risk of dying in a head-on collision by 30%, and they have played a crucial role in making our roads safer.

Airbags are a standard feature in almost 100 million vehicles

Airbags are now a standard feature in almost 100 million vehicles. This is the result of a long history of development and legislative action.

The idea for airbags can be traced back to 1919, when two Birmingham-based dentists, Arthur Parrott and Harold Round, submitted a patent for an "airbag for the covering of aeroplane and other vehicle parts". The patent was approved in 1920, and air-filled bladders were in use by 1951.

The airbag specifically for automobile use is credited to American John W. Hetrick, who filed for a patent in 1952. German engineer Walter Linderer also filed a patent for a similar invention in 1951. Hetrick's design was inspired by his work with Navy torpedoes, and he combined this with his desire to protect his family on the road. Despite working with major automobile manufacturers, Hetrick was unable to attract investment.

The first commercial designs were introduced in passenger automobiles during the 1970s, with limited success and some fatalities. However, broad commercial adoption of airbags occurred in many markets during the late 1980s and early 1990s.

In 1998, the Intermodal Surface Transportation Efficiency Act of 1991 went into effect, requiring that all cars and light trucks sold in the United States have airbags on both sides of the front seat. This legislation was inspired by Ralph Nader's 1965 book "Unsafe at Any Speed", which speculated that seat belts and airbags together could prevent thousands of deaths in car accidents.

Today, airbags are standard equipment in almost 100 million cars and trucks. They are considered passive restraint devices, acting as a supplement to active restraints like seat belts. Airbags are designed to inflate in milliseconds during a collision, providing a soft cushion and restraint for vehicle occupants. They can reduce injuries by providing an energy-absorbing surface between the occupant and the vehicle's interior.

Modern vehicles may contain up to ten airbag modules in various configurations, including driver, passenger, side-curtain, seat-mounted, door-mounted, and more. Airbags have been shown to substantially reduce the risk of fatality in crashes, especially when used in combination with seat belts.

Airbags reduce the risk of death in frontal crashes by 29%

Airbags have been a standard safety feature in cars for decades, but their effectiveness in reducing injuries and fatalities has been well-established. In frontal crashes, airbags reduce the risk of death for drivers by 29% and for front-seat passengers aged 13 and older by 32%. This is a significant improvement in safety, and when combined with seat belts, the risk of death is reduced by 61%.

The history of airbags becoming mandatory in the United States illustrates their importance in road safety. The Intermodal Surface Transportation Efficiency Act of 1991, which went into effect on September 1, 1998, required all cars and light trucks sold in the US to have airbags on both sides of the front seat. This law was the culmination of decades of development and advocacy for airbag technology.

The concept of airbags originated from Navy torpedoes and was first patented as a "safety cushion assembly for automotive vehicles" by John Hetrick in 1953. However, it wasn't until the publication of Ralph Nader's book "Unsafe at Any Speed" in 1965 that airbags gained traction as a potential life-saving measure in car accidents. Congress passed the National Traffic and Motor Vehicle Act in 1966, which mandated seat belts but not airbags.

While airbags began to be installed in some vehicles during the 1970s, there were initial concerns about their effectiveness and safety, especially for children and smaller adults. Improvements in airbag technology and the recognition of their life-saving potential led to their gradual adoption. By the time the 1991 law was passed, airbags were already a common feature in many cars.

Today, airbags are standard equipment in almost 100 million cars and trucks, and they are estimated to have saved more than 10,000 lives since the late 1980s. They are designed to inflate instantly during a collision, providing crucial cushioning and restraint for vehicle occupants. Modern vehicles may have up to ten airbag modules, including front, side-curtain, seat-mounted, and knee bolster airbags, offering comprehensive protection in various crash scenarios.

While airbags are now mandatory in many countries, their specific requirements and regulations vary. For example, in Latin America, airbags are not compulsory in new cars, and some countries only require a minimum number of airbags. In contrast, countries like India have mandated that all new vehicle models introduced after April 2021 have dual front airbags.

In conclusion, airbags have played a crucial role in enhancing road safety, particularly in frontal crashes, where they significantly reduce the risk of death. Their development and mandatory implementation have contributed to a notable decline in fatalities and serious injuries on the roads worldwide.

Airbags are considered passive safety devices

Airbags are considered "passive" safety devices because they are designed to activate automatically during a collision without any action required by the vehicle's occupants. They are a supplemental restraint system (SRS) or supplemental inflatable restraint, acting as a supplement to "active" restraints.

The purpose of an airbag is to provide a vehicle occupant with soft cushioning and restraint during a collision. They can reduce injuries between the flailing occupant and the vehicle's interior, acting as an energy-absorbing surface between the occupant and the steering wheel, instrument panel, body pillar, headliner, and windshield.

Airbags consist of an airbag cushion, a flexible fabric bag, an inflation module, and an impact sensor. During a crash, the vehicle's crash sensors provide crucial information to the airbag electronic controller unit (ECU), which then triggers the deployment of one or more airbag modules within the vehicle.

The first commercial designs for airbags were introduced in the 1970s, but broad commercial adoption occurred in the late 1980s and early 1990s. In 1998, federal legislation in the United States made it mandatory for all cars and light trucks sold in the country to have airbags on both sides of the front seat.

Airbags are now standard equipment in almost 100 million cars and trucks worldwide, and they have been estimated to have saved more than 10,000 lives since the late 1980s.
