What is a 4-point wheelchair tie-down system?

A 4-point tie-down uses four retractors or straps — two at the front and two at the rear of the wheelchair — to secure the chair to the vehicle floor. When combined with a lap and shoulder belt for the occupant, it meets federal ADA and WC18 securement standards for paratransit, NEMT, and school bus transport.

Is wheelchair securement required by law?

Yes. The Americans with Disabilities Act (ADA) requires that all public transit vehicles equipped to transport wheelchair users must have an approved securement system. NEMT providers, paratransit operators, and school bus fleets are all subject to federal and state securement regulations. Failure to comply can result in fines and significant liability in the event of an accident.

What does WC18 compliant mean?

WC18 is the RESNA/ANSI standard that defines performance requirements for wheelchair tie-down and occupant restraint systems (WTORS). WC18-compliant products have been crash-tested to withstand higher load forces than previous standards, providing greater protection for wheelchair users in the event of a collision or sudden stop.

Which wheelchair securement brands do you carry?

We are an authorized dealer for Q'Straint, AMF Bruns, and Sure-Lok — the three leading manufacturers of wheelchair tie-down and occupant restraint systems worldwide. All products meet or exceed WC18 compliance standards where applicable.

What is the difference between an L-track and a Slide N' Click system?

L-track is a recessed floor channel that accepts fittings at any point along its length, giving installers maximum flexibility in retractor placement. Slide N' Click is Q'Straint's proprietary system using pre-set anchor points that allow faster, tool-free securement — popular in high-volume paratransit operations where speed of securement matters.

What is the difference between a manual and retractable wheelchair strap?

Manual straps are fixed-length webbing straps with a hook or loop connection — simple, affordable, and reliable. Retractable systems use a spring-loaded mechanism to automatically take up slack, making securement faster and reducing trip hazards from loose webbing. Electric retractors add powered retraction, ideal for operators or drivers with limited hand strength or mobility.

Do you offer fleet pricing for multiple vehicles?

Yes. We offer fleet pricing for operators outfitting five or more vehicles. Submit your vehicle count, vehicle type, and preferred brand through our Fleet Quote form and a specialist will respond within one business day.

Do your products come with installation instructions?

Yes. All products ship with manufacturer installation guides. We also maintain a full library of installation and user guides on our website for Q'Straint, AMF Bruns, and Sure-Lok products. Our specialists are also available by phone at 800.884.6456 if you need installation support at no charge.

Module 6: Securing the Rider

Free Driver Training · Module 6 of 12

Securing the Rider

The tie-downs hold the chair. The lap and shoulder belt hold the person. In a crash or a hard stop, a rider who is not belted can move forward and out of the chair even when the chair itself has not moved. This module covers where the belts go, how they should fit, and what to do when fit is difficult. Reading time: about 7 minutes.

After this lesson you will be able to:

Place a lap belt and a shoulder belt correctly on a rider.
Tell a crash-rated occupant restraint from a postural or positioning belt.
Handle common fit problems and a rider who does not want to wear the belts.

The two parts of the restraint

The lap (pelvic) belt sits low across the front of the pelvis, on the hip bones and not on the soft abdomen. It should be snug and flat. The shoulder belt runs diagonally across the chest and over the collarbone, away from the neck, and must not be routed behind the rider or under the arm. Together they keep the pelvis and the upper body in the seat.

Safety warningA lap belt that rides up onto the abdomen can cause serious internal injuries in a crash. If the belt will not stay low, stop and adjust before you drive.

Step by step

Place the lap belt low across the pelvis, then make sure it is flat and not twisted.
Fasten the shoulder belt so it crosses the chest and shoulder, away from the neck.
Remove slack until the belts are snug against the body, as the manufacturer directs.
Check that no belt passes over an armrest, wheel, tray or other part of the chair that could change its path.
Press the buckle release to confirm it latches, and tell the rider how to ask for help if they need it.

Where the lap belt anchors depends on the system: some anchor to the vehicle floor, others to the wheelchair frame or to the rear tie-downs. Follow the instructions for your system and chair. Do not move a lap belt to a different anchor than the manufacturer approves.

Not all belts are restraints

Many wheelchairs have their own postural or positioning belt. It helps the rider sit well, but it is not designed or tested as a crash restraint. It does not replace the vehicle's lap and shoulder belt. Use the vehicle restraint as well, and make sure the two do not interfere with each other.

Question answeredCan a postural belt be the only belt? No. A positioning belt supports posture. It is not tested as a crash-rated occupant restraint.

Fit problems and what to do

Situation	What to do
Large or small rider	Use belt extensions or adjusters that the manufacturer approves. Never tie belts together or add a non-rated belt.
Feeding tube, catheter or other medical device	Route the belt around the device and not over it, following the rider's care instructions. Ask the caregiver.
Rider with spasticity, tremor or high muscle tone	Re-check the belts after the rider settles. Ask the caregiver for the best position.
Pressure sores or sensitive areas	Do not omit the belt. Ask the caregiver about padding or placement that does not move the belt off the pelvis.
Chair has a headrest or tray	Make sure neither moves the shoulder belt off the chest, and that a tray is removed or stowed before travel.
Rider says the belt hurts	Re-adjust. Do not remove the belt without a plan.

When a rider does not want the belts

Explain what the belts do and ask what the concern is. Many objections are about comfort or dignity and can be solved by adjusting fit or explaining. Public transit rules mean a transit provider generally cannot require a wheelchair user to wear belts unless it requires belts for every passenger, so know your employer's policy. Whatever the policy, always offer the belts, record a refusal, and never drive with a belt that cannot be used safely.

What the manufacturer saysBelt routing, anchor points, extension options and weight limits for your exact restraint are in its instructions. This module is general guidance. Where it differs, follow the manufacturer.

Key takeaways

Lap belt low on the pelvis. Shoulder belt over the chest and collarbone, away from the neck.
Snug, flat, untwisted, and clear of armrests and wheels.
A postural belt is for posture only and never replaces the vehicle restraint.
Offer the belts every time. Know your employer's policy and record any refusal.
