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 and to allow the client to benefit from the dynamic feature.
Education about the equipment and how and why it works is essential. A DRBi which is latched when not in transportation is not allowing the client to benefit from the dynamic feature.
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.
The DRBi needs to be “un-weighted” in order to be latched / unlatched. If there is weight or pressure put on the DRBi, the elastomers are compressed and the back 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. The re-build kit includes upper and lower elastomers as well as plastic caps for the top of the elastomers.
