The-device further includes an armrest (7, 8, 9, 20) which is connected to the fastening element (6) and has a vertical column (7) so connected to the fastening element as to be rotatable about its longitudinal axis, a horizontal rear supporting bar (8) connected to the column, and a front supporting bar (9) carrying a forearm rest (20), on which the user's forearm is to rest, and being telescopically displaceable in relation to the rear supporting bar (8) in order to form an armrest that can be lengthened and shortened as desired. The rear supporting bar (8) is so mounted on the column (7) as to be pivotable about a horizontal transverse axis (10). A spring means (15, 16, 17, 18, 19) is arranged to maintain the rear supporting bar (8) in an initial position and to counteract, with an adjustable spring pressure, pivotal movement of the rear supporting bar (8) about the horizontal transverse axis (10) caused by a depression of The forearm rest (20).
