Abstract: The invention relates to a movable installation comprising rows of seats. The inventive installation is formed by guides (1) which are housed in the ground and on which the rows of seats (2) are slidably mounted such that they can slide between a position in which they are grouped together and a position in which they are spaced apart. The aforementioned guides (1) define (i) upper extensions which provide a ground leveling reference during the assembly of the installation and (ii) a housing for the insertion of cover plates (10) which are level with the ground.

Abstract: A garnish arrangement in a through-hole of an annular headrest comprises at least one support wire member, a first cylindrical garnish member of synthetic resin material, and a second cylindrical garnish member of synthetic resin material. The support wire member extends across the through-hole of the annular headrest. The first and second cylindrical garnish members each has an engagement element and a stopper element. With this garnish arrangement, the first and second cylindrical garnish members are firmly engaged together within the through-hole at their respective engagement elements, while the support wire member is sandwiched between the stopper element of the first cylindrical garnish member and the stopper element of the second cylindrical garnish member, thereby providing a robust structure against deformation.
