  • Patent number: 9371878
    Abstract: An apparatus for variable shock absorption is provided. The apparatus includes a pair of elastic members that cross each other and a first support that has both ends coupled to predetermined first ends of the elastic members. A second support faces the first support and has oblong grooves in which second ends of the elastic members are inserted to slide in opposite directions. When an external force is applied to the first support or the second support, the distance between the first support and the second support changes and the angle formed by the pair of elastic members changes based on the change of the distance between the supports.
