Armrest unit for work vehicle seat comprises fixed base, armrest and support allowing armrest axial and pivoting displacement

摘要

The armrest unit comprises a fixed base (1), an armrest (3) and a support (4) between the base and armrest allowing an axial displacement (5) of the armrest and its transverse pivoting movement either side respective neutral positions. The support is rotated at the bottom on the base by a transverse rotational spindle (8) and supports the armrest at the top by a rotational spindle perpendicular to that of the transverse spindle. A return spring (10) is interposed between the base and the support and a second return spring (13) is interposed between the support and the armrest.
