  • Patent number: 7980524
    Abstract: A suspension trauma relief device includes a member extending from a ring to which the safety harness and lanyard are attached. The member provides a support for the wearer so that the wearer can take his/her weight off of the safety harness, and particularly the leg straps on the safety harness, to allow blood circulation and prevent suspension trauma. Preferably the member includes at least one foot support allowing at least one of the wearer's feet to be placed in the foot support to take the wearer's weight off the safety harness and avoid any constriction of the straps of the safety harness on the person's blood flow.
