A hydraulic damper (13) is fitted separate from the spring and is also linked to the flexible drive. The enables the whole system to be fitted into a compact, slim housing with only the hydraulic section having to have a reinforced wall. A compact layout has the hydraulic damper and the spring on opposite sides of the pivot axis and linked by the flexible drive.
