The Q'Straint Blog

Welcome! In the Q'Blog, we're writing about anything and everything as it relates to wheelchair passenger securement. Do you have an idea for an article, or a question we can address? Feel free to comment on one of our articles or contact us. Enjoy!

With docking systems, a common question usually comes out. How heavy of a wheelchair can be secured? While the question calls for a simple number, it’s those numbers that can become quite complex.

Without going too far deep into Physics there are two concepts that need to be defined. The first and easiest is the static weight of a wheelchair: This is how much the object weighs standing still. The second concept is much more difficult to define: The effective mass of a wheelchair.

Effective mass of the wheelchair introduces the element of motion. This is hugely important because our QLK systems are tested for a collision, which is the automotive safety standard of 30mph and 20G’s. In over-simplistic terms, the weight of the wheelchair is multiplied by 20 at 20G’s as the impact occurs and this new weight is what our docking system holds.

To add one more mind-bending element to this mix, the effective mass of that wheelchair in an impact is extremely susceptible to many factors that actually reduce how much it ‘weighs’ in a collision. Any piece of the wheelchair that bends, breaks, collapses, shifts over, or stretches will actually absorb energy and therefore reduce the load on our docking system. That is why we not only test real wheelchairs, but also use a surrogate wheelchair for independent testing of the QLK base. It’s ‘static’ weight of 187lbs actually pulls MORE than most real wheelchairs because it does not bend, break, collapse, etc…

So the simple answer is that there is no simple answer. Our QLK docking systems are the strongest docking systems in the world, thanks to their design and other features like heat-treated steel. In fact, our QLK-150 docking system is currently the ONLY system to pass WC19 wheelchair loads.  There is not a stronger docking system out there! If you really want to know what the weight limits of the QLK docking systems are, they’re well past 15,000lbs!

Q'Straint and Sure-Lok Are Committed to Improving Safety by Minimizing Tip Overs

Transportation is crucial in helping individuals with special needs maintain independence. In a world of increasing pressure to meet transit schedules, there may be a temptation to cut corners to keep up. Whether you are driving the school bus, running para-transit, in charge of the city bus, or a small van service such a decision can be particularly hazardous if your passengers are in a wheelchair. If you fail to secure the passenger and their wheelchair properly, and you have to take a sharp turn, they can tip over.

For public transit officials, the ramifications of improper securement can be costly in terms of lawsuits and insurance claims. Nearly 100% of all litigation resulting from accidents involving those in wheelchairs is related to tip overs. Most tip overs occur during normal operation of the transportation – that is, emergencies and weather-related incidents do not play a major role in wheelchair tip overs. You may not be able to prevent 100% of accidents, but you can keep wheelchair passengers safer and decrease liability by using the wheelchair tie-downs and occupant restraints properly.

We realize the products we make are essential to passenger safety, so it is necessary that drivers be well trained. Proper training helps to minimize injuries and prevent accidents. Our commitment to driver training has led us to create best-in-industry driver training program, which is available online and in person at our driver training seminars. If you are not able to attend the in-person training sessions, there are excellent product-specific driver training guides that can be downloaded or viewed online.

It’s time for an about-face in thinking when it comes to wheelchair restraint systems in U.S.-based transit systems. Literally. For decades now, forward-facing safety restraints have been the de rigueur standard. Q’Straint delivers wheelchair passenger safety solutions in more than 50 countries around the world, however, where the standard is the just the opposite.

At APTA in October, we unveiled the Quantum - an innovative solution that we hope will raise awareness of the advantages of the rear-facing setup. Such a turnaround in the way wheelchair-mobile passengers are transported augments their safety and reduces time, effort and costs for public and private transit operators. But more importantly, it strictly adheres to ADA, CSA, and ISO standards while preserving the dignity and independence of the disabled.

Right now, when passengers in a wheelchair want to board a city bus, they must turn their chairs around. The driver must come and safely position the passenger in a forward-facing position and secure the restraints. Our new system will be a breakthrough in terms of eliminating driver interaction. Adopting this approach will lessen the incidence of securement mistakes and cut down on the liability transit operators face.

Around the world, transit systems in the Europe, Asia, and Latin America acknowledge that rear-faced seating is the safest direction for large vehicle transport. Crash test analyses show that most crashes are frontal. The impact from these crashes will send a wheelchair-mobile passenger lunging forward. In the case of a collision, or even a hard brake, forward-facing wheelchair passengers can and often do fall from their chairs.
By restraining chairs to face the back, the impact sends the passengers’ bodies into the supportive surface of the chair behind them. The same logic applies to rear-facing infant car seats. This logic saves lives and prevents injury, not to mention reduces city bus idle times, and promotes independence with wheelchair passengers.

There’s some natural resistance, to be sure. Rear-facing passengers will not be able to see their upcoming stop, but even the most basic public transit systems have auditory and visual alerts for upcoming stops. Facing a different direction is not an issue for the millions of public transit riders in New York City, Washington, DC, Los Angeles, Chicago and Atlanta. They ride facing every which direction each day. Seats are positioned to maximize space, which is another advantage of the Q’Straint product. Staying within the space requirements of the ADA, our rear-facing restraint system will take up less room so transit operators can safely accommodate more people.

It’s a win-win solution, and we’re proud to be pioneering in this area. Stay tuned.

“Never mix, never worry,” goes one old adage embraced by serious drinkers. With the merger of Q’Straint and Sure-Lok, such advice is a reliable rule of thumb for those tempted to mix and match products from the companies.
 
Why the cautionary note concerning two companies who have pioneered safety innovations that are now industry standards?
 
Actually, it’s simple.
 
Both Q’Straint and Sure-Lok have been the market leaders because of our extensive crash testing with verified independent labs. Every fitting, component, belt, piece or other assembly has been tested so that we know the product we are selling exceeds our company standards. The problem with mixing the systems is this: They haven’t been tested together.
 
We can equip you with a Titan automatic retractor with combination lap and shoulder belt for L-Track knowing it’s been tested. Likewise, our QRT MAX with the Slide N’ Click fitting has undergone many tests in different configurations. We know we can offer those complete product lines to our customers with total confidence.
 
So why not just test each product and be done with it? As American humorist H. L. Mencken once said, “For every problem there is a solution that is simple, neat . . . and wrong.”
 
If it only took a few tests to guarantee safety when mixing Q’Straint and Sure-Lok products, it’s a task that would be checked “completed”. However, it gets complicated when you multiply several retractable or manual tie-downs by several fittings, and many lap and shoulder belt combinations, height adjusters, track solutions and other custom options.
 
What’s important to keep in mind is that, until recently, Q’Straint and Sure-Lok were separate companies. It’s not a question of whether our L-Track fittings are compatible (they are) or of product strength (they all meet standardized testing regulations), but of crash testing and documentation.  For now, keeping Q’Straint and Sure-Lok products separate is the recommended way to go as we get to know each other and find ways to improve your customer experience.
 
If this sounds like a focus on safety that borders on obsession, we’ll gladly plead guilty. Our approach to product development has been central to our success: Innovate, test, and  bring our customers the absolute safest and best. Always.
 
So be safe, and don’t mix and drive. And stay tuned for the next wave of great wheelchair passenger safety solutions from Q’Straint and Sure-Lok.

DSC01564On the morning of Tuesday January 11th, our distributor, Tramanco, in Brisbane, Australia was hit with major flooding. During the severe storm, the Wivenhoe Dam had reached capacity and was threatening to collapse. In order to avoid a larger disaster the floodgates were opened, resulting in major flooding.

All of us at Q’Straint were shocked to hear that their building was submerged under 17 feet (5.2 meters) of water and it took more than 4 days before the waters began to recede.

Perhaps what was amazing is how Roger and Judith Sack responded. It’s quite difficult to put such an amazing story on paper when you aren’t really sure where to start rebuilding. Needless to say, we are extremely proud of what Roger and Judith have been able to overcome and wish to share their letter on Q’Straint’s Blog for all the world to see. Click here to open the .PDF!
