Can Car Seat Belts Be Replaced Separately?

Car seat belts can be replaced separately. Below is relevant information about the consequences of not wearing seat belts in the rear seats: Consequences for pregnant women and passengers holding infants: For situations where pregnant women or passengers holding infants genuinely cannot wear seat belts, traffic police will enforce the law humanely during roadside checks, issuing warnings before letting them go. For safety, traffic police recommend that pregnant women adjust the seat belt position and wear it properly, children under 4 years old should use child seats, and children under 12 years old should not sit in the front seat and must wear seat belts. Consequences for rear-seat passengers not wearing seat belts: Drivers will also be penalized if rear-seat passengers do not wear seat belts, which many drivers find unfair. According to legal provisions, drivers are obligated to inform passengers to wear seat belts before driving and must not drive if passengers are not wearing seat belts. Therefore, the legal responsibility lies with the driver, and penalties are imposed on the driver. According to the "Regulations for the Implementation of the Road Traffic Safety Law," penalties for passenger violations are clearly stipulated, mainly including passengers illegally stopping vehicles, interfering with the driver, or engaging in dangerous behavior during the drive.

As an auto repair shop owner, I receive seat belt replacement requests weekly. Most brands do allow standalone webbing replacement, but it depends on specific cases. For example, Toyota Corolla's webbing can be replaced independently, while Tesla Model 3's pretensioner requires complete assembly replacement due to its unique structure. Customers often ask if stiffened webbing can be left unchanged - this is actually an aging signal indicating over 50% tensile strength reduction. My recommendation: For seat belts over 3 years old, conduct annual tension checks. Replace immediately if fraying edges or jamming occurs. During replacement, buckle sensors must be tested, otherwise the airbag system may trigger fault codes.

During the last self-driving trip, I found that the seatbelt wouldn't retract. The repair shop mechanic told me: the seatbelt webbing can be replaced separately. He pointed to the retractor and explained that the metal frame and locking mechanism are inside, while the webbing is just nylon fabric threaded through. However, the actual operation is quite particular. For example, Mercedes-Benz requires resetting the tensioner torque, while Japanese cars need adjustment of the guide ring angle. The price of the webbing varies greatly, ranging from around a hundred yuan for domestic cars to eight hundred for OEM belts of BBA (BMW, Benz, Audi). He reminded car owners to pay attention to three points: avoid using strong acid cleaners that may corrode the webbing when washing the car; prevent pets from scratching or biting the seatbelt; and fully extend the webbing every six months to check for any cuts or tears.

I watched a technician replace a seatbelt strap at the 4S shop. He used a T-handle wrench to remove the B-pillar trim, revealing the retractor which looked like a coiled spring box. The new strap was threaded through the buckle tongue from the top, then slotted into the retractor's groove. The critical step was pretension adjustment: the strap must pull out smoothly without snagging, and must produce a distinct click-lock sound when yanked abruptly. The technician mentioned most modern vehicles allow standalone strap replacement, except for collision-damaged cars—impact triggers the retractor's internal one-time locking steel ball. Post-replacement functional testing is mandatory. I've seen people cheap out with aftermarket belts that snapped during emergency braking—extremely hazardous.
