A sunshade comprises a main post, a canopy frame, and a tilting and rotating assembly mounted between the main post and the canopy frame. Rotation of a handle on the main post in a direction causes the canopy frame to move from a folded state to an unfolded state. Further rotation of the handle in the same direction causes the canopy frame to tilt, and still further rotation of the handle in the s...

A sunshade comprises a main post, a joint rotatably mounted to an upper end of the main post, and a canopy frame pivotally mounted to the joint.
