A sliding seal (10) capable of operating effectively when encountering irregularities and changes in a surface against which it is working. The seal (10) comprises plurality of resiliently flexible seal elements (30) each having an outward extent including an outer portion (32) terminating at a seal tip (33). The outer portions (32) are spaced apart to define gaps (35) therebetween to accommodate deflection of the seal elements. The seal tips (33) are offset with respect to other seal tips in the outward direction. The offset arrangement of the seal tips (33) allows the seal (10) to accommodate irregularities and changes in a surface against which the seal operates.

L'invention concerne un joint coulissant (10) capable de fonctionner efficacement lorsqu'il rencontre des irrégularités et des changements sur une surface avec laquelle il coopère. Le joint coulissant (10) comporte une pluralité d'éléments joint élastiquement déformables (30) ayant chacun un prolongement vers l'extérieur doté d'une partie externe (32) se terminant par une pointe de joint (33). Les parties externes (32) sont espacées pour définir des espaces (35) aptes à s'adapter à une flexion des éléments joint. Les pointes de joint (33) sont décalées vers l'extérieur par rapport à d'autres pointes de joint. L'agencement décalé des pointes de joint (33) permet au joint (10) de s'adapter aux irrégularités et aux changements d'une surface avec laquelle il coopère.
