translate English to French: It follows that in order to determine the meaning of the words 'place ... where the employee habitually carries out his work‘ for the purposes of Article 5(1) of the Convention, as amended by the San Sebastian Convention, in a case where, as in the main proceedings, the employee carries out his work in more than one Contracting State, the Court's previous case-law must be taken into account when determining the place with which the dispute has the most significant link, while taking due account of the concern to afford proper protection to the employee as the weaker party to the contract. Where a contract of employment is performed in several Contracting States, Article 5(1) of the Convention, as amended by the San Sebastian Convention, must be understood to refer to the place where the employee has established the effective centre of his working activities and where, or from which, he in fact performs the essential part of his duties vis-à-vis his employer.
Il s'ensuit que, en vue d'interpréter la notion de «lieu ... où le travailleur accomplit habituellement son travail», au sens de l'article 5, point 1, de la convention, tel que modifié par la convention de San Sebastián, dans une hypothèse où, comme en l'espèce au principal, le travailleur exerce ses activités professionnelles dans plus d'un État contractant, il importe de prendre en considération la jurisprudence antérieure de la Cour en déterminant le lieu avec lequel le litige présente le lien de rattachement le plus significatif, tout en tenant dûment compte du souci d'assurer une protection adéquate au travailleur en tant que partie contractante la plus faible.
