“…Automobile airbag systems are the widespread micro-pyrotechnical systems introduced in the earlies 1970s [1] designed to slow down the movement of the car occupants within milliseconds to prevent injury during a collision [2,3]. Recently, new applicative markets have emerged with the goal to prevent personal injuries during extreme sport (skiing, equitation, motorcycling), urban twowheelers or to protect the elderly from hips fracture when falling.…”

To reduce the size inconvenience of airbag systems employed in human-body protection devices while maintaining comparable gas generation performance, a new family of gas-generating energetic composites are proposed mixing Al/CuO nanothermite with copper complex (Cu(NH3)4(NO3)2) known for its propensity to generate gases (0.03 mol/g) such as N 2 , O 2 , N 2 O through exothermic chemical decomposition (300 J/g). The aluminum (Al)/Copper oxide (CuO) couple, known as the most widely studied nanomaterial for thermite reactions, releasing a high energy, mostly heat, through chemical reaction, is employed as a source of heat to trigger and sustain the decomposition of Cu(NH3)4(NO3)2 complex. This work permits developing a new family of gasgenerating energetic composites that takes advantage of specific chemical and thermal properties of both materials. We demonstrate its capability to tune the pressurization rate, burn rate and pressure peak by varying the Al/CuO over Cu(NH3)(NO2)2 mass ratio. The peak pressure of Cu(NH3)4(NO3)2/Al/CuO energetic composites reaches 12 MPa/g.cm 3 in a close volume, which is 3.3

“…Not wearing seat belts when airbags deployed, hit by a lowpower airbag in comparison to hit by a powerful airbag, inflate unnecessarily in low speed crashes and moving children to the forward seats were described as some reasons that increased the suspicion of airbag related injuries [2,[10][11][12]. Some other ways to reduce these damages include changing steering wheel to reduce the use of airbags in frontal accidents, use of educational programs to ensure the correct utilization of seat belts, and development of smart airbags.…”

This report is about a man of 25 years old (175 cm, 90 kg) who sustained bilateral Le fort I, II, and III fractures because of an inflating car airbag. Despite the fact that airbags harshly reduce both the mortality and morbidity from crashes as intercept frontal collisions, but with increasing use of airbags, increasing number of injuries caused by these devices is inevitable. Reports about serious injuries and even death due to airbag deployment highlight the necessity for a modification in design and speed of airbag deployment for accidents with various speeds.

“…3,6,7 Injuries such as these occur in the second phase of airbag deployment when the inflating airbag has pushed body parts away from the sternum. 8 These injuries have been associated with spontaneous, unwarranted, mistimed or excessive force during deployment where the airbag action has caused greater injury than the impact otherwise would have. 5,7 A higher risk of injury is also associated with particular positions and manners of occupant seating, 8 for example in unrestrained or improperly restrained occupants, especially during low-speed collisions where the airbag punch-out force is disproportionate to the collision force.…”

Airbags are impact-activated safety devices which deploy from the interior of vehicles to protect occupants from trauma during crashes. Although airbags effectively reduce the risk of death and injury, this it is not without issues. For example, high-impact unbelted rigid-barrier testing in the USA led to the adoption of powerful, large airbags that were associated with numerous airbag-related deaths and injuries. In contrast, European designs were tested and certified in conjunction with the use of three-point restraint systems, meaning that the airbags could be smaller with reduced ‘punch-out’ power. An overview is provided of the mechanism of action of airbags and the associated non-lethal and lethal injuries that may be sustained by vehicle occupants.
