A vehicle seat arrangement comprises an upright support for anchoring in a vehicle, which support carries an arm 5 projecting substantially radially therefrom, a seat (1, Fig. 2) mounted on arm 5, a first assembly for adjusting the height of arm 5 and a second assembly for swinging arm 5 in a limited arc about the axis of the support. Preferably, the support includes a tubular column 6 in which the height adjustment assembly may be housed. The height adjustment assembly may be connected to arm 5 via a longitudinal slot 9 in column 6 and may include a screw shaft 12 which is typically engaged at its lower end by an electric motor 18. Screw shaft 12 may be co-axial with column 6 and may be threadedly engaged with a sleeve 13 having a lateral extension 14 through slot 9 to carry arm 5. The support may be fixed and arm 5 may be hinged to the height adjustment assembly. Column 6 may also be rotatable about its axis to facilitate swinging of arm 5. |
