R Healthcare Technical Information Manual - Dash Page 28 March 2007 Revision B
The armrest rear socket fitting on the Dash frame is an injection moulding, swivel mounted and
attached to the side frame.
The single screw fixing acts as a pivot when the armrest is moved from its working position,
allowing the armrest to be swivelled to the rear, away from the occupant for side transfer. The rear
socket moulding has a location hole which engages with a sprung pin in the armrest frame to
locate it in the socket. This feature allows armrest removal from the socket, and completely
detached from the frame for minimum weight lifting, if this is necessary.
These injection moulded frame components facilitate accurate positioning and trouble free
operation, with a significantly reduced risk of problems arising from the effects of corrosion due to
wear during normal use. It should be understood however that they may become damaged in the
event of misuse, typically if the user attempts to force an armrest into the wrong position, or
applies loading when the arm is not correctly located. However, unlike with a fabricated assembly,
replacement of damaged components is simple, from a service aspect, and they are available as
spares in chair sets.
Replacement armrests and armrest component parts are available as spares.
13.0 UPHOLSTERY :
The upholstery seat on Dash is either padded on self-propelled and unpadded on occupant
propelled as standard, with both alternative types of canvas available as options.
The backrest upholstery on Dash wraps around the backrest frame tubes, and is secured to the
upper section by two M5 pozi head screws from each the side. The backrest upholstery features a
central hinge cut out . In order to fit replacement backrest upholstery it is necessary to first
remove the push handle by removing the screw and disconnecting it at the hinge pivot point.
The upholstery on Dash is very strong and durable, and will take a great deal of heavy use.
However if a wheelchair is being recycled from one user to another as is frequent practice in NHS
service centres, it is recommended that all upholstery, and body contact fittings such as armpads
are replaced.
Seat cushions can be included in an original specification of Dash, or supplied subsequently as
individual spares as indicated in the table below.
Note that when replacing screw on type upholstery, this also requires replacement of the securing
screws, as already described for general routines.
Lap straps are standard in an original specification of Dash, and supplied subsequently as spares,
as indicated below.
The strap is attached by means of a bracket.
