According to Japan’s Institute for Traffic Accident Research and Data Analysis, over 75% of all fatalities in passenger car traffic accidents are caused by frontal collisions. The force of these crashes can bend a restrained passenger’s upper body forward, causing the head, face or chest areas to strike the steering wheel or dashboard, resulting in potentially serious injuries.
SRS front airbags deploy on impact in certain types of frontal collisions to help lessen injuries to passengers from being thrown forward. They have been developed and designed to help prevent serious injuries to the head, face and chest. Studies have shown that, when combined with properly fastened seatbelts, this technology can help to reduce the risk of death in frontal collisions by 46%.
How does it work?
SRS front airbags work in concert with the other safety features of a Toyota vehicle to help protect the driver and passengers in serious crashes. When a sensor records a frontal impact that exceeds a certain magnitude, it sends a signal to both the seatbelts and the airbags. Seatbelt pretensioners retract the seatbelts due to collision sensors prior to the occupant’s forward motion, while force limiters then lessen seatbelt tension to an appropriate level as the occupant’s body moves forward into the shoulder restraint. At the same time, the airbags are deployed almost instantaneously to help prevent a vehicle’s occupants from striking the steering wheel or instrument panel. In fact, airbag deployment is so fast that it is completed within only .05 seconds of a collision.
