Crash Test Results wheelchair

Crash Test rolling chair



Standards for wheelchair transportation safety were developed by ANSI RESNA and ISO, which are the US and international standards organizations Those standards require that all fastening system wheelchair restraint system or wheelchair manual successfully pass an electric impact sled test 30 mph 20g.
The appliance manufacturer takes responsiblity for working with the testing facility to meet the sled test requirements Read about the testing process at the University of Michigan Transportation Research Institute.
Only when a transit security technology has passed a sled test is the manufacturer's request that their equipment complies with the Transportation Security Standard These standards describe in detail how the products are designed, tested and labeled you can learn more about the standards on standards section of this website or purchase a copy of RESNA standards.
For the novice, let s Translate the criteria 20g 30mph This means that the wheelchair is security technology in transport and it is the occupant dummy crash test exposed to simulated frontal crash the wheelchair and fictitious experience 30 mile per hour speed change and a deceleration to 20 times the force of gravity.



In real life, for a wheelchair racer 180 pounds 81 6 kg it creates a huge amount of gaming power Twenty grams of 180 lb weight translates into a force of about 3600 pounds Imagine trying to catch a beach ball 3600 lb.
This 20g criteria of 30 mph crash is the same criteria used to test all the cars and child restraints or car seats with the same criteria to test technology Transportation Safety wheelchair is intended to providing equivalent protection for wheelchair racers.
Use the series of videos on the pages below to learn about the value of public transport security technologies Each crash test video shows the contribution of one aspect of technology Transportation Safety docking wheelchair, occupant restraint or the use of a wheelchair WC19 compliant in crash tests were conducted in the test facility at the University of Michigan Transportation research Institute UMTRI.
The best choice for any traveler is to transfer to the vehicle seat and wear seat belts for passengers of the vehicle However, upon transfer to a vehicle seat is too risky or is not possible, a person riding sitting in a wheelchair should use all three parts of the public transport security technology for creating an optimal transportation safety.
The four straps are needed to secure the wheelchair to the floor of a vehicle This method is most often used in transit buses in common transport buses adapted, school buses and vans owned by individuals it works well in these settings because the belts work with many types and styles of wheelchairs standard for testing the strength of the attachment of the wheelchair to the vehicle floor with straps or a mooring system is comparable to the standard used to test the attachment of a car seat or bus on the vehicle chassis.
4-point fixing The aim is to secure the straps to the frame wheelchair right below the combined center of mass of the wheelchair and it's occupant angles from floor to wheelchair are carefully defined in the standard order they stabilize the chair and prevent tipping, rotation and forward movement.


It is important to use the 4 straps Some bus drivers, transportation and passenger assistants could consider only grant the straps that are easiest to reach Do not use the 4 straps up too much of a burden on straps that are used and can also lead to tipping.
The videos below show different scenarios such as not only use or using the attachment of a front and a back belt The last video shows the use of all four straps.
This is a frontal impact test 30mph wheelchair unsecured and unoccupied substitution.
This is a frontal impact test 30mph an unoccupied wheelchair replacement secured by four tie-down straps.
After the wheelchair is fixed to the vehicle floor, the next goal is to keep the rider in a wheelchair in the wheelchair Most vehicle-related deaths and injuries occur in side effects such as when the occupant strikes the inside the vehicle or is ejected from it.
Only the bony parts of the body can withstand the forces exerted on the body by restraining the occupant An occupant restraint device acts as 3 points seatbelt in a car Part of the best pass basin low and tight on the pelvis.



The part of the breast comes from the wall of the vehicle and crosses the clavicle and breast bone anchored in the pelvis If the occupant restraint does not cross bony areas, significant soft tissue injuries can happen.
It is important to use the 3 parts of the restraint All vehicles must have a way to change the point of origin of the wall chest strap on the vehicle Setting this origin enables the restraint of torso to fit either a big or small person.
Just because a wheelchair has a seat belt with an automotive style loop or the airline does not mean that this belt is a belt Most positioning belts are not anchored to the frame of the wheelchair They are simply screwed into the seat rails.
The following videos using wheelchairs replacement of a wheelchair designed for repeated crash tests to demonstrate the retention contribution of the occupants 3 points.
The first video shows the consequences of the use of all not binding This gives a visual clear vision of the meaning of secondary impacts.
The second shows the consequences of using after market positioning devices such as butterfly harnesses, belts hook and loop, etc.



The third shows the extreme movement of the chest that occurs when only the pelvic part is used, it does not mean avoid side effects.
The fourth video shows the extreme movement that occurs when only part of the breast from shoulder is used This movement, called submarining, may cause significant injuries to internal organs or obstruction of the airway.
The latest video shows the protection offered by an occupant restraint properly positioned, 3 points.
This is a frontal impact test 30mph without restraint belt of the occupants.
Harness E g of the chest, straps with hook and loop, or after market pelvic belts.
This is a frontal impact test 30mph using only postural support belts.



This is a frontal impact test 30 mph using only a retained anchored pelvic belt vehicle.
The use of a restraint belt occupant that moves on the armrest of the wheelchair instead of the body against snugging This allows the movement called pickling that has the potential to cause fatal injuries to internal organs, neck and This of airways is a frontal impact test 30mph by means of a belt restraint vehicle three-point anchored with the pelvic girdle placed on the armrest of the wheelchair.
The use of a three-point occupant restraint snugly This is a frontal impact test using a 30 mph properly positioned, anchored vehicle belt restraint at three points.
Compatible WC19 wheelchair is the latest part of the transit security technology This ANSI RESNA, adopted in April 2000 describes a wheelchair that can withstand the forces of a crash The US standard for wheelchairs transportation of tested is similar to ISO and Canadian standards.



After the wheelchair is fixed to the vehicle floor and the wheelchair passenger is belted using restraints, the next goal is to host the passenger in a wheelchair designed for a seat in a motor vehicle From many wheelchairs are not suitable points for other wheelchair fastening straps chairs do not allow attachment to the correct height on the frame of the wheelchair driver of the vehicle is left guessing the best location.
Other executives in wheelchairs are not strong enough to withstand the forces of a pulse crash test sled Just because a wheelchair has a seat belt with an automotive style loop or the airline does not mean that this belt is a belt.
Most positioning belts are not anchored to the frame of the wheelchair They are simply screwed into the rails Velcro belts and positioning loops with an offer inadequate protection accident under high loads.
If a wheelchair is labeled as compliant WC19, it means that this model of wheelchair is available with a frame and crash tested transit equipment and a safety belt anchored in wheelchairs.



T he wheelchair when configured with these options, sleigh is tested with the appropriate size of the test dummy as the standard requires that the site updated, complete list of compliant WC19 wheelchairs.
WC19 The standard aims to ensure that a wheelchair is more easily secured and the occupant is more easily retained these features makes it easier to comply with the first two parts of the transit safety technology system; fixing the wheelchair 4 points and occupant restraint to 3 points.
The following videos show the contribution of a wheelchair WC19.
The first video is a wheelchair not in accordance with WC19.
The second video is an adult in an electric wheelchair complies WC19.



The third video is a child in a manual wheelchair complies with WC19.
The fourth video is a child in an electric wheelchair complies with WC19.
