ABSTRACT:
An adjustable-height armrest is provided with an armrest column, an armrest carrier which is telescopically displaceable in height on the column, an arm support located thereon and a catching system for fixing the armrest carrier with respect to the armrest column in graduated height positions. The catching system consists, on the one hand, of a double row, extending vertically in the armrest column, of mutually aligned latching recesses which are connected to one another via slots. A locking unit comprising two mutually engaging locking bolts which are displaceable relative to one another is also arranged on the armrest carrier. These locking bolts each have a latching head for the latching recesses and a narrower web adapted to the contour of the orifices. The webs are aligned with the orifices when the locking unit is released.
