The seat belt is the first line of defense in keeping you safe in the event of an accident. But you may be asking yourself how seat belt works. Let’s dive in. In a seat belt system, the webbing is connected to a retractor mechanism. Attached to one of the ends of the webbing, is the spool. This is the main element in the retractor. Inside the retractor is a spring that applies rotation force, or better known as torque, to the spool. This is what causes the spool to rotate, winding up any loose webbing.
The seat belt retractor has a locking mechanism that stops the spool from rotating. The retractor can be triggered by the car’s movement. The spool locks when the vehicle decelerates rapidly, like when the vehicle is in a collision. The retractor can also be triggered by something jerking the seat belt webbing.
In some newer seat belt systems, a pretensioner does the job of tightening the seat belt webbing. Unlike the conventional locking mechanism in a retractor that simply keeps the belt from extending any further than it is before the accident, a pretensioner tightens any slack that may exist. It pulls in the seat belt webbing. When an accident occurs, the gas in the pretensioner ignites, causing the pressure that builds up to rotate the retractor. Pulling back any slack in the seat belt puts the individual firm in their seat as to minimize the damage that person may receive during the accident. Pretensioner work together with the conventional locking mechanisms, rather than in place of them.
Seat belt help to keep you safe in your seat in the event of an accident. Though they are very important, some people, driver or passenger, choose to put their life at risk by not using them properly. Some try to avoid hearing the sound or seeing the light warning you that the seat belt is not buckled. They do this by buckling the seat belt behind them. However, now the seat belt can’t protect them. Others just choose to ignore the seat belt all together. The seat belt can not protect you if it is not being used properly. Others, use the seat belt the way it should be: stretched across the chest and buckled in. However, if the seat belt is damaged at all, it can not fully protect you even if you are using it. If their is an issue with your seat belts, it is important to get it resolved right away.
A few things to look out for is if your seat belt is constantly getting jammed, not retracting, if your seat belt pretensioner gets blown during an accident, or if a dog chewed up the seat belt. Seat belts can also get worn, frayed, or stretched out. All of these may result in your seat belt not being able to do its job in protecting you.
You may require Toyota Corolla seat belt replacement. If you go to a dealer, you should expect to spend hundreds of dollars. Often, getting the seat belt repaired is enough to resolve the issue. However, sometimes that is just not an option. You need it replaced all together. Rather than going to a dealer, you can go to a professional like Safety Restore.
Safety Restore is a post accident restoration company that specializes in seat belt repair and replacement as well as all other services regarding your vehicles Supplemental Restraint System. They can do the Toyota Corolla seat belt replacement for a fraction of the cost at the dealers.
Since you are already getting the seat belts replaced, this may be a good time to finally get those new seat belt webbing colors you may have been wanting. Safety Restore has dozens of colors. They offer the regular colors like tan, black, or grey. If you are feeling adventurous, they also offer colors from camo green to ferrari red, and even black with orange stripes on the edges for that little pop of color to change the look and feel of your Toyota. They also use a professional automated sewing machine that ensures clean stitching on the webbing.
Believe it or not, fraying is one of the most common problems that people face with their seat belts over time. After many years of use—fastening and unfastening a seat belt—the material webbing can get caught on sharp objects, hooked on clothing, or get chewed on by pets. The fraying may start off pretty minimal but if left untouched it could turn to extensive ripping or even a completely torn seat belt! The problem is, many people do leave it be and only tend to the problem when it gets quite bad. The result is a less than attractive vehicle interior as well as a possible impingement on safety.
The reason fraying can be looked at as a big problem rather than a minor one is because it can cause a number of other issues with the seat belt. A frayed seat belt may have difficulty entering and exiting the seat belt mechanism. As a result, that can leave a lot of slack in the seat belt. When there is a lot of slack, ultimately the seat belt cannot serve its purpose. A properly functioning seat belt should be securely fastened up against an occupant’s lap and reach across the chest and shoulders—without too much extra space between the occupant and the seat belt. This way, it will protect the occupant and lock up against them in the event of a sudden stop or collision. If there were to be any slack, an occupant may suffer extensive injuries from the airbags and/or may bang their head up against the steering wheel. Clearly, that is not how seat belts are intended to work.
When you are unbuckled in your seat, have you seen the seat belt sign go off? Ever wonder how seat belt sensor works? Seat belt sensors/switches are used in various industries including the automotive and the airline industries. They may soon even become mandatory on buses and trains as well. A vehicle can include several types of sensors: weight sensor passenger seat, speed sensor, and connection sensors in buckles. There are conditional actions that are based on the sensors state. They cause the dash indicator light to light up or for the alarm to go off inside.
The Reed Switch exists inside a seat belt buckle and determines whether or not the passenger is wearing their seat belt. It has been known by seat belt designers as being the most reliable way to detect if the seat belt has been engaged. If your vehicle can turn the airbag on or off by its own, the sensor can light up the airbag display stating if it is active or not. This occurs when it senses that their is pressure on the seat, someone is sitting on it, but has not put on their seat belt. The sensor inside the seat belt buckle also can light up the symbol resembling a person belted into their seat. This occurs when the passenger is not buckled in their seat.
You may be buckling in and out of your seat belt every day (and perhaps five or six times at that!) but have you ever stopped to think about the seat belt assembly and what the different parts that make up the entirety of the seat belt are? Today I will explain just that. There are a few main parts to the seat belt: the pretensioner, the retractor, the pillar loop, and the material webbing. All are equally important in the assembly and functionality of the seat belt.
To start with, the pretensioner is one of the most important components of the seat belt. It is otherwise simply known as the seat belt “buckle”. This is the female part of a safety belt that secures and releases the retractor, or tongue, of the seat belt that is attached to the material webbing. It is manufactured to hold the retractor in a firm position so that it has no chance of unbuckling on its own. It also allows for the seat belt to be fastened and unfastened with very little force by the user. If someone needs to free themselves from their seat belt, the seat belt buckle should be easy to unbuckle and maneuver out of.
Another important component that was briefly mentioned is the seat belt retractor. This is the male portion of the seat belt that actually fits into the seat belt pretensioner. It attaches to the material webbing.
Of course, the material webbing is also very important. Seat belts are designed so that the webbing can reach across an occupants lap and over their chest and shoulders. This allows for the force from a possible collision to be spread across the body rather than be focused on one single area—thus causing more serious injury. Usually, the material webbing is made from polyester and has a large tensile strength to support quite a bit of weight.
Finally there is the pillar loop. Although this portion of a seat belt is smaller in comparison to the other components, it serves an important function. It is used in 3-point seat belt systems and is located above the shoulder of an occupant. Its main purpose it to guide the webbing over the shoulder and across the occupant’s chest, so as to provide that maximum security that was mentioned above.
You probably put on your seat belt every time you step into your vehicle. But have you ever stopped and looked at the individual parts of the belt? Do you know what each of the parts are called and what their function is? Let me help you with one of the most important parts of the seat belt: the pretensioner.
Basically, the pretensioner—otherwise known as the buckle—is the female portion of a belt where the seat belt latch actually buckles into.
It operates by using an explosive charge to drive a concealed piston when the sensors perceive the distinctive abrupt deceleration of an accident. As a result, the piston very quickly drives the spool around which the fabric material of a seat belt is wrapped. The rapid retraction of the seat belt webbing removes the slack from the seat belt immediately. This additional seat belt “pre-” tension—right before the actual full force of collision—pulls occupants firmly against their seats. This allows them to receive the maximum protection benefit from the airbags located at the front of the car.
Usually it is pretty easy to tell if the seat belt pretensioner is bad. You can scan your car with an OBD airbag scanning tool and check if any codes pop up. Even though this is the proper way, you can also visually inspect your seat belt buckle to see if anything is wrong with it. It will have a compressed, or “squished in” look if it is broken.
As with any type of mechanism that is used often, seat belts can become faulty and need repair and/or replacement.
When it comes to replacement of seat belts, new ones can be purchased at the dealership. At the dealer, you can expect to pay hundreds, if not thousands, of dollars for a new seat belt. It will be a quality seat belt, but imagine how much you’d have to pay for a whole set of them for your car! Another option when trying to replace the seat belts in your vehicle is searching online in places such as eBay. Others choose to head over to a junkyard to buy affordable replacement seat belts there. Although junkyard belts may not always be the best in terms of functionality or safety, they are certainly cheaper than new seat belts at the dealer. You can end up buying seatbelts at a junkyard for as little as $30!
Of course, there are still other options available for people with faulty seat belts. Many do not know this, but seat belts can actually be fixed—they do not always have to be replaced! Some people choose to purchase the necessary tools needed for the job, find informative instructions online, and attempt the repairs from home.
If you don’t see yourself being the latter type of individual (not everyone is hands on, after all!) but you also don’t want to spend hundreds of dollars at the dealer or risk buying belts at a junkyard, you have still another option. You can turn to the company Safety Restore.
There are many things that can go wrong with a seat belt, but having a seat belt that doesn’t lock is perhaps the most frustrating. You may be experiencing this problem yourself. Perhaps you can hear the belt click into the latch but the actual latch does not clasp onto the belt. Lucky for you, there are things you can do to fix this annoying situation. Read on to find out.
One likely reason you are having this issue is because there is something stuck in the actual seat belt buckle. Using a screwdriver or something flat and pointy such as a butter knife, poke around the entrance of the buckle. Something little such as a pebble, hairpin, or the like may have become lodged into the mechanism and been the cause of the problem all along!
If you find nothing imbedded into the seat belt buckle, it may just be some grime buildup inside of it. Try shooting some lubricant—WD-40 or Tri-Flow should do the job—into the seat belt buckle. Hopefully, that will allow whatever is gummed up inside to disperse.
If that doesn’t work either, you may have a greater issue at hand. You may have to entirely replace the seat belt buckle if you ever want it to lock properly again. Basically, what you’ll need to do is unclip the plastic shroud that is located on the right side of the seat once it is out of the car. After that, the buckle should pivot on a 14 mm bolt. Some people choose to buy a replacement buckle at a junkyard, while others buy one at the dealer.
As can be anticipated from many years of use, there are a ton of things that can go wrong with a seat belt. One of the main problems people face is having a safety belt that will not pull out. If you are experiencing this same issue yourself, read on. I will be addressing a few possible techniques to fix a seat belt that isn’t pulling out—hopefully one of them works for you! With any luck, you won’t need to ask the question, “Why does my seat belt keep locking?” any longer!
To start with, one obvious option you have is purchasing brand new seat belts at the dealer. Of course, this will come with a hefty price tag, but you’ll be left with brand new safety belts that shouldn’t give you any problems for the next couple years.
If you don’t want to spend all that money required at the dealer, you can try to fix your seat belt from home. One thing that may be cause of your seat belt having a difficult time pulling out is grime or sweat buildup on the belt. You may not want to think about it, but sweat does come off of our bodies and builds up on our clothing or whatever our body comes in contact with—seat belts included. Pair that up with dirt caused by constant handling, and you have a pretty gross situation at hand. Over a few years of use, the sweat and dirt can be so packed into the seat belt that it becomes rigid and pretty firm to the touch. A simple solution that you can apply from home is the tried and true soap and water. Soak your belt(s) in the soapy liquid for a few hours, then let it air dry. After doing this, you’ll probably notice how much more flexible the belt will become and hopefully it will retract into the seat belt mechanism much more smoothly.
If this technique doesn’t yield the results you are looking for, the problem may lie in the retractor itself. You’ll have to manually disassemble the mechanism and use a screwdriver to spin the spool. Hopefully this will let the seat belt retract into the mechanism more easily.
Seeing as how seat belts are one of the most crucial safety components in a vehicle, many people think that any little problem with them necessitates buying brand new ones at the dealer. That cannot be further from the truth. Although new belts can certainly be purchased, it wouldn’t be practical to spend all that money if the results would be identical after a simple seat belt repair! Seat belts really can be repaired and restored to factory settings if handled properly.
