Most of us would like to save a few bucks on car maintenance. Some people are even willing to walk a few more steps to purchase a cheaper alternative. If you see yourself doing this, you might scoff at the thought of buying a new seat because of a small tear.
If you are this type of person, you will find professional seat belt repair services invaluable. Their help will come in handy if you want to fix a locked seat belt after an accident. Their services are also useful if only a portion of your seatbelt is torn.
What Is a Seat Belt Pretensioner?
We commonly call it a seat belt. We rarely bother to understand its different parts, but this knowledge may come in useful when the repair man gives tips on how to take care of the seatbelt. With this said, let us define what a seat belt pretensioner is. It is the device connected to the safety belt buckle, safety belt retractor, and/or outboard lower safety belt anchor assembly.
More importantly, we must understand how it works. This knowledge would prevent accidents because we would know if it is time for a buckle pretensioner repair before the problem becomes obvious. You can tell if the device is functioning with the combination of the following:
- An accident triggers the airbag module’s electronic activation process.
- The triggered pyrotechnic gas generator activates the pretensioner.
- This pretensioner activation tightens the seatbelt.
It does not necessarily mean that you need to have a buckle pretensioner repair if the airbag module does deploy the airbag because it does not always do that. Beyond those three points, you must understand that pretensioners activate as a result of certain accidents or crashes. Here are a few of such unwanted scenarios:
- frontal accidents or crashes
- side accidents or crashes
- rear accidents or crashes
- rollover accidents or crashes
Take note that the buckle pretensioner uses a pyrotechnic gas generator that propels the piston. Once it activates, the safety belt buckle pulls the buckle down toward the seat. Thus, it tightens and locks the belt.
The anchor pretensioner also uses a pyrotechnic gas generator that propels the piston. Once an accident activates it, the outboard lower safety belt anchor assembly’s cable pulls the buckle down toward the floor. Thus, it tightens and locks the belt.
Driver and Passenger Belts Are Stuck after an Accident and the SRS Airbag Is On
When this happens, it does not mean that you need a buckle pretensioner repair. On the contrary, it means that the device is working. Remember that car manufacturers designed the seat belt pretensioners to lock during an accident.
Safety belts save lives. It is essential that they are always in working condition because it is a matter of life or death. With this said, if you see something wrong with them or perhaps, they are torn, you should have them inspected immediately.
