Patent ID: 8596722

Claim:
A machine operator seat of a construction machine, comprising: a seat surface having a front seat edge; a backrest which is situated opposite to the front seat edge in the longitudinal direction of the seat surface; and at least one armrest situated laterally to the seat surface, comprising: a base part; an arm support; and at least one operating element, the arm support being situated in a rear area in the longitudinal direction and the at least one operating element being situated in a front area of the armrest in the longitudinal direction, wherein the arm support is mounted via a guide device on the base part of the armrest, the guide device comprising: a sliding carriage including a support plate having a tab extending toward the base part on each of the opposing sides in the longitudinal dimension of the support plate, a spring guide rail, on which a restoring compression spring is situated, extending between the two tabs, at least one stop element, which is displaceable along the spring guide rail, situated at one axial end of the restoring compression spring, and at least one stop provided on the base part, which is implemented to obtain a restoring function in such a way that it fixes the at least one stop element in relation to the base part in one displacement direction and thus causes a compression of the restoring compression spring during a longitudinal displacement of the support carriage, the guide device being implemented in such a way that the arm support is freely displaceable with respect to the base part in a predetermined longitudinal displacement range along the longitudinal direction, and further wherein the guide device is implemented to be self-positioning in such a way that the arm support automatically moves into a starting position with respect to its positioning in the longitudinal direction in an unloaded state.
