Whether the supplemental restraint system activates during a rear-end collision is dependent on several factors. These include the severity of the impact, the direction of force, and the specific design and programming of the vehicle’s airbag system. Front airbags are primarily designed to protect occupants in frontal or near-frontal crashes, while side airbags offer protection in side impacts. Vehicle sensors are calibrated to detect specific deceleration thresholds associated with these types of collisions. Therefore, a rear impact may not trigger front airbag deployment unless the vehicle is also subjected to a significant forward force or deceleration.
The purpose of airbag systems is to mitigate injury risk during a collision by providing a cushioning effect. This helps to prevent occupants from impacting the steering wheel, dashboard, or windshield. The development of these systems has significantly reduced the severity of injuries sustained in automobile accidents. However, airbags are not a universal solution for all accident scenarios. Their effectiveness is optimized for specific impact types and may not be beneficial or necessary in low-speed collisions or rollovers. Furthermore, the deployment of an airbag can, in certain circumstances, present its own risks, particularly for individuals who are improperly seated or too close to the airbag module.
