Abstract: Examples of hinge assemblies are described. In an example implementation, a hinge assembly includes hinge elements which are interconnected to move the hinge assembly between a folded position and an unfolded position. The hinge assembly further includes elastic members disposed between the hinge elements at a first side and a second side thereof. When the hinge assembly is moved from the unfolded position towards the folded position, elastic members at the first side are decompressed and elastic members at the second side are stretched. When the hinge assembly is moved from the folded position towards the unfolded position, elastic members at the first side are compressed and the elastic members at the second side are destretched.
