Zusammenfassung:	An active seat suspension system (10) comprises a base frame (12), a seat carrier frame (14), and a linkage (16) mounted on the base frame (12) and supporting the seat carrier frame (14). The linkage (16) comprises a first link (19) which is pivotally coupled to the base frame (12) and the seat carrier frame (14). The linkage (16) further comprises a second link (21) which is pivotally coupled to the base frame (12) and the seat carrier frame (14) and which is pivotally coupled to the first link (19) about a link pivot axis A. A rotary motor (70) has an outer housing (72) and an output shaft which rotates with respect to the outer housing (72). The outer housing (72) is coupled to the first link (19) and the output shaft is drivingly coupled to the second link (21), so that rotation of the output shaft relative to the outer housing (72) causes the first and second links (19, 21) to rotate relative to each other and varies a space between the seat carrier frame (14) and the base frame (12).
