The elastomers last approximately 2 years, depending on the frequency and forces applied. We have a “re-build kit” which will restore the elastomers to new condition, just like a “tune-up”. These can be purchased and installed by your wheelchair supplier.
No, the color/strength of the elastomers should be the same on each side. Having different colors/strength will cause possible failure or breakage of the back and the back seating system.
Carrying any heavy object on the back or looped around the back canes will adversely affect the DRBi function and is not recommended.
Call or visit your supplier.
Occasionally you may want to latch the DRBi when pushing a manual wheelchair over rough terrain to prevent excessive movement, but remember to unlatch as soon as possible to prevent breakage of the DRBi .
Education of the equipment and how and why it works is essential. A DRBi which is latched when not in transportation is a waste of money and is not helping the person in the wheelchair.
The DRBi should be unlatched all the time, except when the wheelchair is being transported with the client in the chair. Remember to unlatch the back as soon as the wheelchair and client leave the vehicle.
No. A recliner back and a DRBi cannot be used together.
The DRBi needs to be “un-weighted” in order to be latched. If there is weight or pressure put on the DRBi compressing the elastomers, it cannot be latched smoothly.
If you are still having difficulty, the DRBi may need adjustment. The supplier may need to adjust the bolt going through the elastomers.
If the DRBi is more than 2 years old, the elastomers may need to be replaced. We have a re-build kit for this, which may be obtained through the supplier.
Yes, in some cases, allowing the person in the wheelchair to move improves comfort, resulting in less movement. After dynamic parts are installed, active extension may be reduced over time as forces are absorbed.
