PROPOSAL FORACOUNCIL
DIRECTIVE ONTHE APPROXIMATION OPMEMBER STATES'
LAWS ONTHE INTERIOR FITTINGS OFMOTOR VEHICLES
(Strength ofseats andtheir anchorages )
(submitted totheCouncil bytheCommission )
COM(73 )682final

EXPLANATORY MEMORANDUM
This proposed Directive istoform part oftheCommunity type-approval
procedure referred toinCouncil Directive 70/156/EECof6February 1970 (1)„
On15September 1971 ,France notified theCommission ofadraft order
concerning the strength ofseats and their anchorages inprivate cars .
The Commission asked France todelay the implementation ofthe draft or­
>der .France complied with itsrequest .Itisthus necessary toforward
aproposal for aCouncil directive onthis subject .
The proposal concerns technical requirements for the design and testing
ofinterior fittings inrespect ofthestrength ofseats andtheir an­
chorages .
Indrafting itsproposal ,theCommission based itself onthework (2)ac­
complished inthis field bytheEconomic Commission forEurope ,inGeneva ;
asfar astrade isconcerned ,this isbound tooffer anadditional ad­
vantage asavery large number ofstates arerepresented intheECE .
TheDirective isapplicable tomotor vehicles with atleast four wheels
and amaximum design speed exceeding 25km/h(Article 1).
Article 2incorporates therequirements forsuch interior fittings into
the EECtype-approval procedure .
(1)O.J. No.L42,25February 1970 .
(2)Regulation No.17"Uniform provisions concerning theapproval of
vehicles with regard tothe strength ofthe seats and oftheir an­
chorages (Doc .E/ECE/52^;E/ECE/TRANS /505 Rev. 1/Add .16).

Assome newMember States have nonational type-approval procedure yet ,
aspecial article had tobeincluded toensure that vehicles meeting
therequirements ofthedirective (Article 3)could beused inthese
States (1). -
Iftheprototype ismodified ,theMember State which has approved it
shall decide whether newtests must becarried out (Article k),
Article 5provides for theadaptation ofthespecifications intheAn­
nexes inline with technical progress ;theprocedure isdefined in
Article 13oftheCouncil Directive of6February 1970 ontheapproval
ofmotor vehicles and their trailers .
Article 6 )lays down twotime-limits .Before theexpiry ofthefirst
time-limit ,theMember States must adopt andpublish thenecessary mea­
sures tocomply with theDirective ;they may dosoatanytime inthe
intervening period .Thesecond time-limit isthedate onwhich allthe
Member States must simultaneously apply thecommon rules (Article 6(1 ))..
Finally ,theCommission must beinformed with reasonable notice ofany
provisions theMember States intend totake inthe field covered bythe
Directive ;theinformation must besufficient for theCommission tobe
able tocomment ontheproposed provisions ifnecessary (Article 6(2 )).
CONSULTATION OFTHE EUROPEAN PARLIAMENT AND ECONOMIC AND SOCIAL COMMITTEE
Pursuant totheRome Treaty ,Article 100(2 ),theopinion ofthese two
institutions isrequired .

nity ,and inparticular Article 100 thereof ;
Having regard totheproposal from theCommission ;
Having regard tothe opinion oftheEuropean Parliament ;

Whereas thetechnical requirements which motor vehicles must satisfy
pursuant tonational laws relate ,inter alia ,tothe interior arrange­
ments for thestrength ofseats andtheir anchorage ;
Whereas these requirements differ from oneMember State toanother ;
whereas itistherefore necessary that allMember States adopt thesame
requirements either inaddition toorinplace oftheir existing rules ,
inorder ,inparticular ,that the EEC type-approval procedure which was
thesubject ofthoCouncil Directive of6February 1970 ontheapproxi­
mation ofthe laws oftheMember States relating tothe type approval
ofmotor vehicles and their trailers may beapplied inrespect ofeach
type ofvehicle (+);
Whereas common requirements onthe interior ofthepassanger compartment

facing part oftheeeats were laid down bytheCouncil Directive of...(
whereas requirements ontheinternal arrangements fortheprotection of
thedriver against thesteering device inthe event ofimpact were laid
down bytheCouncil Directive of...(+++); whereas other requirements
ontheinternal arrangements ,andnotably those concerning the head
restraint ,the attachment points ofsafety belts ,and themarkings of
thecontrols ,will beadopted subsequently ;

RESULTS ■
When themanikin hasbeen setupasdescribed initem kabove ,
the "H"point andtheactual seat-back angle .ofthevehicle
seat considered areconstituted bythe "H"point andtheangle
ofinclination ofthe manikin 'storso reference line .
Theco-ordinates ofthe "H"point inrelation tothree mutually -
perpendicular planes ,andtheactual seat-back angle ,shall be
measured forcomparison with thedata supplied bythevehicle
manufacturer .
VERIFYING THE RELATIVE POSITIONS OFTHE "R»AND "H"POINTS AND
THE RELATIONSHIP BETWEEN THE DESIGN SEAT-BACK ANGLE AND THE
ACTUAL SEAT-BACK ANGLE
Theresults ofthe measurements carried out inconformity with
item 5»2 .for the "H"point and theactual seat-back angle shall
be'compared with the co-ordinates ofthe "R"point and the de­
sign seat-back angle assupplied bythevehicle manufacturer ..
Therelative positions ofthe ,,R"point and the "H"point and
therelationship between thedesign seat-back angle and the
actual seat-back angle shall beconsidered tobesatisfactory
for theseat inquestion ifthe "H"point ,asdefined byits
co-ordinates ,lies within alongitudinal rectangle whose hori­
zontal andvertical sides are 30mmand 20mmlong respective­
lyandwhose diagonals intersect atthe "R"point ,and ifthe
actual seat-back angle i'swithin 3°ofthedesign seat-back
angle .
Ifthese conditions .are met ,,the "R"point and thedesign seat-
back angle shall beused for the test and ,ifnecessary ,the
manikin shall besoadjusted that the "H"point coincides with
•the "R"point and theactual seat-back angle coincides with
the design seat-back angle .
Ifthe "H"point ortheactual seat-back angle does notsatisfy
therequirements ofitem 6.2.above ,the "H"point ortheactual
seat-back angle shall bedetermined twice more (three times in
all).Iftheresults oftwoofthese ,three operations satisfy
therequirements theresult ofthetest shall beconsidered
tobesatisfactory .

Annex II
Ifatleast twoofthe three test results donotsatisfy the
requirements ofitem 6.2.,theresult ofthetest shall be
considered tobenot satisfactory .
Ifthesituation described initem6,b,above arises ,orif
verification cannot beeffected because the manufacturer has
failed tosupply information regarding theposition ofthe "R"
point o.rregarding thedesign seat-back angle ,theaverage
oftheresults ofthe three determinations maybeused and
beregarded asapplicable inall cases where the "R"point or
thedesign seat-back angle isreferred tointhis Directive .
For verifying therelative position ofthe "R"point and the
"H"point and therelationship between thedesign seat-back
angle and theactual seat-back angle inaserially-produced
vehicle therectangle referred toinitem 6.2 .above shall
bereplaced byasquare of30mmside and theactual seat-back
angle shall not differ bymore than 5°from the design seat-
back angle .
