Airbag Deployment Doors

Airbag systems are just one of many safety systems found in cars and other vehicles. Using sensors, airbags are deployed from the steering wheel when a collision or impact is detected. This helps to prevent the user from injury. Once a sensor has detected the conditions for an accident, it takes a total of 50 milliseconds to trigger and deploy the airbag. Once deployed, airbags can hold from 55 to 120 litres of gas.

The airbag itself is typically made of woven nylon fabric and the inflated air is either nitrogen or argon gas (non-toxic). In most cases, the airbag will come out at a speed of between 100 to 220 miles per hour.

Considering these speeds, the deployment needs to be precise in order to prevent damage to the bag or user. A key benefit of Hytrel® is the ability to mould thick and thin regions in the same tool allowing the designer to create a thin seam. When the air bag deploys only this seam tears, so the cover remains in one piece and no flying parts of the air bag door enter the vehicle interior.
