Abstract
Abstract An adjustment device is provided for use with a pelvis and/or lordosis support arranged in a back support connectable with a seat. The adjustment device contains an axially movable, threaded spindle (2) guided in a housing (1), a threaded ring (4), and an adjustment handle (3), and the housing (1) and the threaded spindle (2) each have an axial, central bore (6, 7) for passing through the cable line (9) of a Bowden-cable arrangement (10). The bores (6, 7) are aligned with each other, whereby the central bore (6) in the threaded spindle (2) has ha hollow space directed at the adjustment handle (3) for inserting and holding a nipple (14) of the one end of the cable line. Provision is made in the side wall of the housing (1) for a radial opening (11), and in the side wall of the threaded spindle (2) for a cross bore (12) ending within the zone of the holding of the nipple (14). The radial opening (11) and the cross bore (12) are aligned with each other in a mutual position of the housing (1) and the threaded spindle (2), forming a passage with a diameter permitting the nipple (14) to pass through, whereby the opening (11) and the cross bore (12) are each connected with the central bores (6 and 7, respectively) by a slot (15 and 16, respectively) permitting the passage of the cable line (9).
