Abstract: A securement apparatus for connecting a plurality of riders together on a vehicle is provided. The securement apparatus includes a pair of harnesses having a first harness coupled to a first rider and a second harness coupled to a second rider, and a linkage assembly connecting the first and second harnesses together, the linkage assembly having a first arm with a first end coupled to the first harness and a second end, a pivot arm with a first end pivotably mounted to the second end of the first arm and a second end, and a third arm with a first end pivotably mounted to the second end of the pivot arm and a second end coupled to the second harness. The pivot arm is designed to pivotably adjust relative to the first and third arms to adjust the separation distance between the first and second harnesses.
