Reviewed by: Adrianos Facchetti, Esq. California State Bar No. 243213. This page has been reviewed for personal injury information specific to California and pertaining to injury cases where the seat belt has failed in a crash.
It will be hard to attribute liability for defective seat belts simply because there was an injury caused in an accident. It is the job of a Los Angeles seatbelt failure injury accident lawyer to find out whether the restraint system behaved reasonably during the accident in question and, if it failed to do so, whether it was because of that failure that injuries were sustained. There are usually two liabilities associated with such claims. The first is the liability for the accident itself. The second one is the liability for a defective restraint system, which has made an accident more injurious. Our experience with a Los Angeles car accident attorney practice might help you with those questions.
Seat Belt Failure May Occur in Multiple Ways
The restraint system consists of many parts, each of which may malfunction and affect the way the occupant is restrained. Different failure modes should be proved separately.
False Latching or Buckle Release
The buckle may seem completely fastened to the occupant but may not have been properly fastened at all. If the crash happens, the partially latched condition would be released. It is indeed a failure mode, but one cannot confirm its occurrence based on finding an opened buckle after the crash. The belt is often unfastened by the occupant or emergency personnel following the crash.
Retractor Failure
The retractor controls the webbing and, according to the design of the particular restraint system, is supposed to lock during an applicable crash situation. Some of the issues that may arise include lack of locking when it should be locked, payout of too much webbing so that the occupant will be positioned too far ahead, or even a mechanical failure of the retractor. Retractors vary from one vehicle to another, meaning that there are different abnormalities for each one.
Pretensioner Failure
Most current restraint systems have pretensioners, which, according to NHTSA, are systems designed to automatically wind the seat belt and take out any slack created by a crash. In cases where the car comes with pretensioners, there may be more movement allowed in the car compared to what was intended due to an issue with their deployment. There is no standardization for all cars when it comes to pretensioners and whether or not they were supposed to be triggered.
Webbing or Anchorage Failure
Examples of such defects include cut or broken webbing, weak webbing due to aging, belt anchor failure, and other hardware failures at the belt anchorage points. Damage to webbing resulting from a severe accident is not necessarily a sign of a manufacturing defect, as webbing may be cut by force during an accident even if working properly. Establishing the existence of premature failure would normally require testing or engineering assessment.
Crash Claim and Seat Belt Defect Claim Are Separate Claims
It is important to remember that the cause of the crash and the possible defect of the restraining system can be separate. There are different parties and evidence in such cases, as well as different insurance companies that may cover them.
The example would be a car hitting another one after running the red light. The driver’s negligence is the first liability issue. However, if a defective seat belt releases at the moment of the crash, allowing an occupant to collide with the vehicle interior or even being thrown out of it, then additional damage caused by this releasing becomes the second product liability issue.
It is referred to as crashworthiness or enhanced injury. It means that the vehicle must ensure safety for its occupants in the case of a predictable crash. If a safety system does not work properly in the crash, then the additional injury becomes a subject to a separate claim.
However, enhanced injury is not proved by the severity of injuries only. There are medical documents, biomechanical analysis, and crash reconstruction required to separate the injuries caused by a crash from additional injuries.
Preserve the Vehicle and Seat Belt Before the Evidence Changes
In a seat belt failure case, the vehicle and its restraint system are often the single most important evidence available, and both can be lost quickly.
Potentially important physical and documentary evidence includes:
✓The seat belt buckle and latch plate
✓The retractor assembly
✓The webbing itself
✓The pretensioner, where the vehicle has one
✓Seat belt anchorages and mounting hardware
✓The seat structure
✓Warning lights or stored diagnostic information
✓Electronic vehicle data, where the vehicle records it
✓Photographs of the vehicle interior before anything is moved
✓Documentation of the occupant’s seating position
✓Crash damage patterns
✓The vehicle’s repair history
✓Any prior collision history
✓Manufacturer information for the specific model and restraint system
✓Recall records
✓The police collision report
✓Witness accounts
✓Medical records
Do not attempt to dismantle, test, or manipulate the seat belt or its components yourself. Qualified engineers and other experts generally need to examine the restraint system under controlled conditions, and handling components improperly can compromise or destroy the evidence entirely.
What you can control is preventing the vehicle from being destroyed, salvaged, substantially repaired, or altered before that examination happens. Not every vehicle stores the same electronic data, so what’s recoverable varies by make, model, and year. Evidence preservation can become urgent long before any filing deadline approaches, since insurance companies and salvage yards often move quickly after a total loss determination.
Federal Safety Standards Can Help Frame the Investigation
Restraint systems in vehicles sold in the United States are subject to federal safety requirements, and those standards can provide a reference point for expert analysis.
Several Federal Motor Vehicle Safety Standards are relevant here. FMVSS No. 209 addresses seat belt assemblies themselves. FMVSS No. 210 addresses seat belt assembly anchorages. FMVSS No. 208 addresses occupant crash protection more broadly.
An expert investigation may compare the actual restraint system in your vehicle against applicable federal standards, the manufacturer’s own design specifications, and the physical crash evidence. That said, a federal standard violation does not automatically establish civil liability under California law. These standards help frame what a restraint system was supposed to do, but proving a California product liability claim still requires establishing the specific elements of that claim.
Who Could Be Responsible for a Defective Seat Belt Injury?
Responsibility depends on what actually failed and why. Potentially responsible parties may include:
- The vehicle manufacturer
- The seat belt or restraint-system manufacturer
- A component supplier that produced a specific part
- A distributor or seller, where legally applicable
- A repair facility, if negligent repair or replacement work contributed to the failure
- Another driver who caused the underlying collision
Different defendants may be responsible for different portions of the harm. The driver who caused the crash may bear responsibility for the initial impact injuries, while a manufacturer may face a separate claim for injuries allegedly worsened by the restraint failure.
Under California law, product liability claims may proceed on theories including manufacturing defect, design defect, failure to warn, or negligence, depending on what the evidence supports. The Judicial Council of California Civil Jury Instructions set out the elements required for each of these theories, and they differ meaningfully. A manufacturer is not automatically liable simply because a seat belt failed during a crash. Defect, causation, foreseeable product use, and the other required elements still have to be established through evidence.
What If the Individual Was Not Wearing His Seat Belt?
The fact that the individual had no seat belt in California does not mean that his right to file a lawsuit will disappear.
There is a particular seat belt law in California Section 27315 of the California Vehicle Code, that deals with liability issues if someone fails to wear his/her seat belt. First of all, a citation for not wearing a seat belt is one thing while its influence on a lawsuit is something else.
It is usually raised as an argument when a claimant tries to prove his comparative fault and it is a factual question, not a bar for compensation. Whether the non-wearing of the seat belt really caused some particular harm and to what extent can be determined only based on the crash and injury facts.
Severe Injuries Requiring Evidence that the Failure Affected the Injury
Injuries arising from restraint system failure include brain trauma, facial injury, spinal injury, fractures, internal injuries, chest and abdominal injuries, and ejection injury.
Having any of these injuries does not prove that the seat belt was defectively designed or manufactured. The critical issue in such cases is whether the restraint system failure caused or significantly increased the severity of the injury when compared with the proper functioning of the safety system.
In case the evidence justifies the claim, compensatory damages may include emergency room expenses, hospitalization, operation, physical therapy, medical treatments in the future, loss of income, decreased earning ability, pain and suffering, disability, disfigurement, and others. The average settlement amount in cases of seat belt failures cannot be accurately determined.
California Filing Deadlines and Evidence Deadlines Are Not the Same Thing
Many California personal injury and product liability actions are generally subject to the limitations framework in California Code of Civil Procedure § 335.1.
Exactly when that clock starts and whether exceptions apply can depend on the facts, including accrual questions, whether a public entity is involved, whether the injured person was a minor, and other statutory exceptions.
The more practical point is that evidence deadlines usually arrive long before legal deadlines. A vehicle that gets repaired, sold, salvaged, or crushed in the weeks after a crash takes the restraint system with it, and no filing deadline extension brings that evidence back. A failure involving another occupant-protection system can raise similar crashworthiness questions, as discussed in our guidance on airbag non-deployment injuries.
