How would you check the passive restraint system after an accident?
What will be an ideal response?
When a vehicle has been in an accident, all of the parts of the passive restraint system will have to be checked. The seat belts are inspected for fraying and ease of operation. Pull the web all the way out of the retractor to give it a thorough inspection. Connect the ends of the buckle to be sure it clicks and releases correctly. If a problem is found, replace the belt assembly.
Check the centrifugal belt retractor by pulling it hard. Centrifugal force should make it catch. The belt should be able to move out of the retractor when it is pulled slowly. A pendulum belt retractor depends on the vehicle stopping quickly to provide inertia to set the belt. During a road test, brake suddenly at a speed over 10 mph to determine if this retractor is working.
When seat belts are equipped with pretensioners, you can tell they were deployed if the belts are difficult to buckle. A pretensioner that has been deployed must be replaced.
