Patent number: 10926885Abstract: A mount system provides vibration isolation and support through a hybrid hard-soft configuration. The mount system includes a frame and a body connected with the frame. A first coupling element is provided on the body and defines a first opening. A second coupling element is provided on the frame and defines a second opening. A pin extends through the first and second openings to couple the body to the frame.
