Zusammenfassung:	A swing drive mechanism (110; 200) for a swing having a swing seat, at least one hanger arm (40) supporting the swing seat (52, 54), and a pivot shaft (130) providing reciprocal motion to the swing seat via the at least one hanger arm is described. The drive mechanism may include a gear (114), an eccentric element (116) coupled to the gear and a motor mechanism (110) configured to drive the gear. The drive mechanism may also include a substantially elongated drive link (120) having a proximal end (122) and a distal end (124), the proximal end coupled to the gear via the eccentric element, and a spring (126; 234) coupled to, and configured to being driven by, the distal end of the drive link. The spring being configured to directly drive the pivot shaft in a reciprocal fashion. A swing drive assembly including a blade (154) and pivot shaft (130) is also described.
