What are some car seatbelt failures?

The components of an automobile seat belt are mainly the belt (strap) that is the main body, the buckle that is the receiver for fixing the seat belt, the tongue plate attached to the tip of the belt, and the retractor that winds up the belt. Some of the most common problems with automobile seatbelts are that the belt cannot be fixed due to a defective buckle, and that the warning lamp does not go out even when the seatbelt is fastened. In addition, there is a symptom that the take-up mechanism does not work due to a malfunction of the retractor and the seat belt cannot be returned. And if you use it for a long time, the belt may fray. If people of the same shape are using it, the place where it rubs against the anchor every time the seat belt is fastened is limited, and the place where the force is applied is also fixed, so it may gradually fray. The original function of the seatbelt is exhibited when a large G (gravity) is applied due to an accident etc., so if you say that the seatbelt is out of order during normal use, such a symptom is presumed. ..

What are the causes of car seatbelt failures?

The seat belt is fastened and unfastened as many times as you get in and out of the car. If you operate the device this much, problems such as distortion and poor contact may occur. Buckle failure is thought to be mainly due to wear / damage of metal parts and poor contact of contacts. In addition, it is possible that dust collects inside the buckle or foreign matter gets mixed in and it does not work well.

What is the method / flow of replacing / replacing a car seat belt?

When replacing the seatbelt assembly, first remove the B-pillar trim to expose the body with the seatbelt retractor and pretensioner. Wiring is provided on the main unit to input signals that activate the pretensioner and force limiter functions. Since this wiring is usually connected with a coupler, you can remove the coupler, but since the warning light may not turn off after the work is completed, it is better to remove the battery terminal or fuse before work. It will be good. After removing the coupler, remove the bolts of the belt tip fixing part, the upper folded part fixing part, and the main body fixing part, remove the whole, attach it in the reverse procedure, connect the wiring as before, and the work is completed. The main body has a built-in ball sensor that detects tilt, and if it tilts, the belt cannot be pulled out, so pull it out at the same angle as it is attached. If you write the procedure, it seems that you can easily replace it by yourself because the parts composition is relatively small, but recent seat belts have various functions such as a pretensioner to protect the safety of the occupants. Airbags are also linked. Seat belts can be life-threatening if they don’t work well in the event of an emergency, so we recommend that you ask a professional to do the work if you need to replace them.
