  • Reason
    The original tie-down brackets fitted to these wheelchairs are not suitable for the new heavy duty four point webbing tie-down systems manufactured by unwin safety systems limited. the mhra previously issued mda/2008/014 in march 2008 to alert users of typhoon and typhoon ii powered wheelchairs weighing over 140kg that there was no commercially available four point webbing tie-down system suitable to allow these wheelchairs to be used as a seat in a motor vehicle. mda/2008/035 was subsequently issued in may 2008, on the same subject, for some storm and all storm tt powered wheelchairs that weighed over 140kg. in june 2008 invacare issued a product update (ref pu249) that announced the availability of a new tie-down system from unwin safety systems to enable these wheelchair models to be used as a seat in a motor vehicle. however, the product update failed to advise that the existing tie-down brackets must be replaced by new brackets prior to use of the new tie-down. the original brackets have edges that can damage the webbing of the new tie-down; the new brackets are designed to reduce this risk. in the event of a vehicle impact damaged webbing could fail, leading to injury of the wheelchair occupant or others. the new tie-down brackets are available free of charge from invacare, complete with fitting instructions, for any of the affected wheelchairs. the reference numbers are: sp1523487 – for storm3 (including true track (tt) sp1523488 – for typhoon i sp1523486 – for typhoon ii note: invacare is not providing brackets for storm or storm2 models.
