ULTRA-THIN CALF SUPPORT ASSEMBLY

An ultra-thin calf support assembly may have a base and a leg support bracket rotatably mounted on the base. A first extension plate may be slidably mounted on the leg support bracket. A link assembly may be provided between the first extension plate and the leg support bracket. The movement of the link assembly may be able to pull the first extension plate to slide relative to the leg support bracket. A transmission assembly may have a driving crossbar and linkage plates. One end of the linkage plate may be hinged to an end portion of the driving crossbar, and the other end thereof may be hinged to the base. A middle portion of the driving crossbar may be associated with the link assembly. When the leg support bracket rotates forward relative to the base, the transmission assembly is able to force the link assembly to move.
