õhupadjad

Õhupadjad, commonly known as airbags, are a vehicle safety device designed to inflate rapidly in the event of a collision, protecting occupants from severe injury. They are a supplementary restraint system, meaning they work in conjunction with seatbelts. The primary purpose of an õhkpadi is to cushion the impact between an occupant and the vehicle's interior components, such as the steering wheel, dashboard, or doors.

The deployment of an õhkpadi is triggered by sensors that detect a sudden deceleration, indicating a potential crash. These sensors send a signal to an inflator unit, which rapidly produces nitrogen gas to fill the fabric bag. The entire inflation process takes milliseconds, creating a cushion that softens the occupant's forward motion. Once inflated, the õhkpadi begins to deflate through vents, allowing the occupant to move more freely and reducing the risk of suffocation.

Modern vehicles often feature multiple õhupadjad, including frontal, side, curtain, and knee airbags, each designed to protect occupants in different types of collisions. The effectiveness of õhupadjad is well-documented, and they have been credited with saving countless lives since their widespread introduction. However, it is important to note that õhupadjad are most effective when occupants are properly seated and wearing their seatbelts. Children, especially infants, should not be placed in the front seat of a vehicle equipped with an active õhkpadi.
