Abstract
A vehicle seat, in particular a utility vehicle seat, has a seat frame which can be pivoted by a pneumatic spring and which can be adjusted in terms of height. An adjuster (20) establishes the actual value of the height of the seat frame. The adjuster (20) has a cable roll (22) which is supported on a first portion of the seat frame so as to be able to be rotated about an axis (A), and a cable (24), which can be at least partially wound on the cable roll (22), unwound therefrom and is secured to a second portion of the seat frame that can be moved relative to the first portion, and which controls at least one control valve (36) of the pneumatic spring in accordance with a desired value of the height of the seat frame. A gear mechanism (30) creates an operational connection, in particular a gear connection, between the cable roll (22), a desired value generator (32), by which the desired value of the height of the seat frame can be adjusted, and a control device (34) which controls the at least one control valve (36).
