Could reduce the risk of death resulting from a side collision by approximately 37% 3.
Nineteen percent* of passenger car fatalities occur as a result of side collisions, ranking them second after frontal collisions. Of these, 73% receive serious injuries to head, chest and so forth4. This fact has led to the development of SRS curtain shield airbags and SRS side airbags, which help restrain the head, chest, etc. during side collisions. It has been reported that these airbags can reduce the death rate resulting from side collisions by as much as 37%.

Airbag deployment is completed within only 0.03 of a second of a collision.
Since a door can intrude into the cabin space quickly in a side collision, airbags must be deployed extremely quickly. When a sensor stored in the center pillar detects an impact exceeding a certain magnitude at the time of a collision, the side airbags stored in the seatbacks deploy in 0.02 of a second and the curtain shield airbags stored in the roof above the side glass deploy in 0.03 of a second, softening the impact that the head and chest receive when colliding with a door or other objects from outside the vehicle. Roll-sensing curtain airbags deploy during a rollover, and by remaining inflated for 3 to 6 seconds, help soften the impact on the vehicle occupants.

Airbag deployment is completed within only 0.05 seconds of a collision.
The combination of SRS front airbags and seatbelts is designed to help reduce injuries. When the sensor detects an impact exceeding a certain magnitude at the time of a frontal collision, it sends a signal to the seatbelts and airbags. Seatbelt pretensioners retract the seatbelts and force limiters control the belt tension to an appropriate level. At the same time, airbags deploy instantaneously, helping prevent the occupants’ bodies from striking the steering wheel or instrument panel. SRS knee airbags are also available to better restrain the passenger by catching the lower part of the body.
