6.Seatsettings
6.1Seatheight
SHERPAisavailableinthreedifferentseatheights(45/48/50cm).
Theseatheightisdeterminedbythesizeoftherearandfrontwheel,as
wellasthewheelforkused.
Highestholeposition=24“
Secondhighestholeposition=22“short/longfork
Thirdhighestholeposition=16“short/longfork
Lowestholeposition=12“
6.2 Seat depth
SHERPA‘sseatdepthisadjustablebetween29-54cm.Thisisthe
sameforallsizes.
Bylooseningthe4screws(twoleft/tworight)onthebackrestjoint,the
completebackrestcannowbepushedbackwardsandforwardsinrelati-
ontotheseatsurface.
Thentightenthescrewsagain.

13
Ifasidepanelisinstalledontheexistingwheelchair,thismustbe
removedbeforetheadjustment.
Todothis,boththefrontscrewconnectionstotheframeandtherear
frameaswellastherearscrewconnectionstothewheelsuspension
mustberemoved.
6.3Activedegree
Theactivedegreedescribestheratioofthepositionofthebackrest
relativetothedrivewheelaxis.Thefurtherthebackrestissetbehind
thethedrivewheelaxle,themoreactiveSHERPAcanbedriven.
Important!Thissettingoftheactivedegreecanbemadeaftertheseat
shellhasbeenprofessionallyassembled,thusenablingthedesignerto
anexact,subsequentadjustmentofthecentreofgravity.
Toadjustthecentreofgravity,loosenthe4screws(twoleft/right)onthe
undersideoftheseatproletube.
Thenthecompleteseatunitcanbemovedinrelationtotheseatframe
supportandthemobilitybaseconnectedtoit.
Finally,tightenthescrewsagain!
6.4Backheight
ThebackrestheightofSHERPAcanonlybeadjustedwiththesystem
backrestincombinationwithabackrestpanel.
Thegeneraladjustmentrangeis42cm,butmax.10cmabovethese-
lectedbackrestprolelength.
Backprolelength40cm=backheight47-51cm
Backprolelength45cm=Backheight52-56cm
Backprolelength50cm=Backheight57-61cm
Toadjustthebackrestheight,theupperscrewstotheframeandthe
lowerscrewstothebackrestpanelmustbeloosened.
Dependingonwhichheightsareadjusted,itmaybenecessaryto
removethelowerscrewsandmovethemtoanotherslottedhole.

14
Theuniversalbackframeoffersageneralbacklengthrangeofapprox.
30cmonwhichotherbacksystemscanbemounted.
6.5 Tilt in space
SHERPAoffersaroller-mountedcentreofgravitytiltinspacefrom-7°to
+45°.
13positionsof4°eachcanbeindividuallyadjusted.
Thetiltistriggeredbyalockingpinpull,whichiscontrolledbyarelease
leveronthepushbarorpushhandle.
6.6Backangleadjustment
SHERPAoffersbackangleadjustmentfrom80°to123°.
7positionsofapprox.6°eachcanbeindividuallyadjusted.
Theangleadjustmentistriggeredbyapositivelockingpinontherear
side.

15
6.7 Seat width
Inprinciple,SHERPAisavailableinxedseatwidths.
SB36,40,44and48cm
However,theseatunitisalsodesignedtosupportaseatshellthatalso
extendsbeyondthelateraledgeoftheseat.
Thisispossiblewithoutrestrictionfor12“and16“wheels,asthesedo
notreachtheheightoftheseatunit.
Forthe22“and24“wheelvariants,itispossibletousethevariowheel
cover.
Here,awideningoptionofeither4.5cm,6cmor7cmplusseatwidthis
ensuredvialaterallymountedbrackets.Thisdependsonthemountingof
thebracketoppositethewheelcoverand/orthebaseplate.
Especiallyfortheassemblywithaseatshell,thebackforseatshellscan
alsobeused.
Thishasapivotpointspeciallyadaptedtoseatshellsandenablesthe
bodytobeattachedalmostform-ttingly.

16
6.8Lowerleglength
SHERPAcanbeequippedwithseveralfootresthanger
Shownhere:Footresthanger(xed,angleadjustableor
singlefootrests)forshortorlonglowerleglengths.
short=20-36cm
long=20-41cm
Theheightofthefootrestisadjustedbylooseningtheclampinglevers.
Thenadjustthefootresttothedesiredheightandtightenitagain.
ShownhereistheVariofootresthanger.Standard80°,
