When to replace wheelchair tie-downs and occupant belts: after a crash, by wear, and by age

The four reasons to replace

A wheelchair tie-down or occupant belt comes out of service for one of four reasons. Age alone is not one of them.

1. It was in use during a collision. Q’Straint’s retractor instructions say to replace any system or component that was used during a vehicle collision, including the floor and wall anchorages.
2. The webbing is damaged. Cuts, fraying and contamination from oil, fuel, polish or chemicals all mean replacement.
3. The hardware is broken or worn. Hooks, keepers, latch plates, buckles and fittings that do not work right take the whole assembly out of service.
4. The retractor will not lock or retract. A strap that pays out under load is not restraining anything.

The rest of this guide covers how to spot each one, what the warranty does and does not tell you, and how to record the replacement. The securement standards guide covers how the equipment is tested and used.

After a crash

Q’Straint’s wording leaves no room for judgment. Its instructions for the QER electric retractor, in both the warnings and the care section, say to replace any systems or components, floor and wall anchorages included, that were used during a vehicle collision. The instruction has no speed threshold and no exception for crashes that look minor.

Other guidance leaves the call to the maker. The University of Michigan’s Ride Safe brochure, written for wheelchair riders and caregivers, says that after a vehicle crash you should check with the manufacturer to determine whether the equipment needs replacing. In practice that sends you back to the maker’s instructions, and for Q’Straint those instructions already answer the question.

The reasoning is the load. Tie-downs and belts are tested in a 30 mph, 20 g frontal sled test, and RESNA notes that WC18 adds a second test with the lap belt anchored to the wheelchair, so the tie-downs carry part of the force of restraining the rider as well as the chair. Q’Straint’s replacement rule does not depend on visible damage.

After any collision with a wheelchair rider on board:

1. Photograph each wheelchair position before anything is unhooked, if it is safe to do so.
2. Note which tie-downs, belts and anchorages were attached and in use.
3. Remove those parts from service, tag them, and keep them until the insurance claim and any investigation are closed.
4. Have a qualified installer inspect the track or pockets and the floor around them before new parts go in.
5. Add the replacement cost and parts list to the crash file.

The vehicle accident guide covers the rest of the steps after a crash, and the collision repair guide covers the van itself.

Wear: webbing first, then hardware

Most replacements happen because of wear, and the signs are in the webbing. Q’Straint says frayed, contaminated or damaged webbing should be replaced, and lists the contaminants to keep away from it: oil, gases, polishes and chemicals, battery acid in particular. BraunAbility’s manuals say any cut, fraying or malfunction calls for replacing the entire strap or belt assembly, not just the damaged length.

The federal seat belt standard shows what webbing has to survive. FMVSS 209 requires belt webbing to keep at least 75 percent of its required breaking strength after an abrasion test, at least 60 percent of its original strength after light exposure, and at least 85 percent after exposure to micro-organisms. Those are the conditions to watch for in a van: edges rubbed fuzzy on the floor or a seat frame, webbing faded by sun through the windows, and mildew from straps put away wet.

Hardware gets the same treatment. BraunAbility tells owners to stop using and replace immediately any strap, belt or hardware showing damage, wear, abnormal condition or improper operation, naming hooks, keepers, latch plates and receptacles. It also warns against altering straps or belts. Q’Straint says its systems should not be repaired, adjusted or modified without its written approval.

Much of the wear is avoidable:

• Keep straps off the floor. Q’Straint recommends a storage device, such as its wall pouch, at each wheelchair location. Straps on the floor get stepped on, rolled over and soaked.
• Wash them the right way. Q’Straint says to clean webbing periodically with mild soap and water, then dry it fully extended so water does not get into the retractor.
• Keep belts away from sharp edges. Both Q’Straint and BraunAbility warn about sharp corners and objects.
• Check them often. BraunAbility’s service schedules say to inspect strap and belt assemblies frequently, and warn that severe weather, environment and heavy usage dramatically reduce the system’s life.

Retractors that will not lock or will not retract

A retractor that will not lock is an out-of-service condition, not a nuisance. Check each retractor before the shift as its instructions describe, and take any that will not hold out of service.

Some problems are use errors. VMI’s manual warns not to let belts twist inside the retractor. Q’Straint’s electric retractor instructions describe webbing that does not fully retract and the fix: pull it all the way out, let it retract fully, and compress the webbing onto the reel. If the retractor still misbehaves after that, it comes out.

Others are defects, and there have been several recently. Q’Straint recalled certain QRT-Deluxe and QRT-Max retractors in September 2025 (NHTSA recall 25E063) and certain QRT-3 retractors in April 2026 (recall 26E022), in both cases because the retractors may not lock. Converters filed matching vehicle recalls, among them Braun’s 25V759 for converted Pacifica, Sienna and Odyssey minivans and Vantage Mobility’s 25V877. Under 49 U.S.C. 30120, when a recall notice is required, the manufacturer must remedy the defect without charge. Search each van’s VIN on NHTSA’s site and call the equipment maker with the retractor’s part number. The used wheelchair van guide lists the full set of recent conversion recalls.

Age and warranty

Neither Q’Straint’s nor BraunAbility’s manuals set a fixed age for replacement. They replace by condition and after collisions. What age does give you is the end of the warranty, which is a sensible time for a closer inspection and a budget line.

Q’Straint’s limited warranties run from 1 year on track and pockets to 5 years on QRT-360 retractors, and the retractor and the track it locks into are covered separately.

Q’Straint offers product warranty registration, so register new equipment when it goes in and keep the install invoice in the van’s file. A conversion warranty may also cover the factory-installed securement, so read it before paying for a part: VMI, for example, warrants equipment it fabricates and installs for 3 years or 36,000 miles. The wheelchair van warranty guide covers how the chassis, conversion and equipment warranties fit together.

Replacing the track and anchorages

Q’Straint’s collision rule reaches the floor. Its instructions name floor and wall anchorages among the components to replace after a crash, and BraunAbility says L-track must be clean and not worn, bent or otherwise damaged in a way that keeps fittings from attaching properly.

Anchorage work belongs with a qualified installer. Q’Straint says an experienced technician should perform installation, inspection and maintenance, that anchorages should not go into corroded metal, wood, plastic or fiberglass without suitable reinforcement, and that bolt threads should be cleaned and re-coated with permanent thread locker whenever bolts are adjusted. The tie-down track guide covers track types, layout and adding track to a van.

Matching the replacement to the system

Replace like with like, and buy parts labeled as complying with WC18. The University of Michigan’s Ride Safe guidance says to use only tie-downs and belts that have been crash tested and labeled that way. Q’Straint certifies its OMNI anchorages for both its own and Sure-Lok retractors, but says all four retractors in a 4-point securement must be the same brand, never mixed. The converter’s options list is the easiest way to order the right part. BraunAbility’s guide for its Commercial Infloor Simple Stow, for example, lists an extra M-Series securement kit (29012K) and extra sets of QRT Max (31490K), QRT Deluxe (26558K) and QRT-360 (509070K) retractable belts, each with four tie-downs, a lap and shoulder belt and a bag.

An upgrade is a reasonable time to change systems, as long as all four tie-downs at that position change together. Swapping one strap at a time across brands is what the maker warns against.

Keeping a replacement log

A replacement log answers the questions a broker, insurer or investigator will ask: what was in the van on a given day, and why it was changed. Keep one line per part:

• Date and van. Include the wheelchair position, front left or rear right for example.
• Part. Maker, model and part number, and the lot or date code if the label has one.
• Reason. Collision, wear, contamination, retractor fault, recall, or upgrade.
• Who did it. In-house or the installer’s name, with the invoice number.
• What happened to the old part. Kept for a claim, returned under warranty or recall, or destroyed.

Cut condemned webbing before it goes in the trash, so nobody puts it back in a van. The wheelchair securement checklist covers the daily checks that feed this log.

Catching worn straps at shift start

Worn and damaged straps are easiest to catch at the start of the shift. In HealthRide, drivers complete the inspection checklist in the app when they check out a vehicle, and dispatch sees failed inspections immediately. Pre-shift checklists are stored with the shift, ready for an audit. See the fleet page.
