COUNCIL DIRECTIVE
of 18 December 1975
on the approximation of the laws of the Member States relating to
anchorages for motor-vehicle safety belts
(76/115/EEC)
THE COUNCIL OF THE EUROPEAN COMMUNITIES,
Having regard to the Treaty establishing the European Economic
Community, and in particular Article 100 thereof,
Having regard to the proposal from the Commission,Having regard to the opinion of the European Parliament (
1),
Having regard to the opinion of the Economic and Social Committee (2),
Whereas the technical requirements with which motor vehicles must
comply pursuant to national laws relate inter alia to safety belt
anchorages;
Whereas those requirements differ from one Member State to another;
whereas it is therefore necessary that all Member States adopt the same
requirements, either in addition to or in place of their existing rules, in
order, in particular, to allow the EEC type-approval procedure, which
was the subject of Council Directive 70/156/EEC of 6 February 1970 on
the approximation of the laws of the Member States relating to the type
approval of motor vehicles and their trailers (3), to be introduced in
respect of each type of vehicle;
Whereas common requirements for the interior fittings of the passenger
compartment, the layout of the controls, the roof, the backrest and rear
part of the seats were laid down by Directive 74/60/EEC (4); whereas
common requirements on interior fittings relating to the behaviour of the
steering mechanism in the event of impact were laid down by Directive
74/297/EEC (5); whereas common requirements concerning the strength
of seats and their anchorages were laid down by Directive
74/408/EEC (6); whereas other requirements will be adopted sub-
sequently concerning interior fittings, and in particular safety belts,
head restraints and the identification of controls;
Whereas approximation of the national laws relating to motor vehicles
entails recognition by the Member States of the checks carried out by
each of them on the basis of the common requirements; whereas, for it to
operate effectively, such a system calls for the implementation of these
requirements by all of the Member States with effect from the same date,
