The arrangement comprises partly a support arm (1) with a support part (16) for the lower arms of the operator, and partly a guide (2) comprising at least one guide rail (7) which is retained relative to the keyboard. The support arm is articulately and displaceably connected to the guide rail so that the support part can be adjusted to and locked in a position providing the required distance and height position relative to the keyboard. - The guide (2) comprises two rails (7) located at a distance from one another, each of which incorporates a displaceable slide (3) in which the support part (16) is pivotably located. An adjustable stop device is fitted on the slide to stop the support arm in the adjusted position, and the support arm is formed as a stirrup (1) with two projecting arms (13,14) by means of which it is articulately fitted on the two slides. |
