INTEGRATED FALL-PROTECTION HARNESSES AND EXOSKELETONS AND METHODS FOR USE
Integrated fall-protection harnesses and exoskeletons are disclosed that include cooperating connectors to removably couple the exoskeletons to the harnesses. The exoskeletons may include an arm support including an arm rest for receiving an arm of the user and one or more compensation elements configured to apply an offset force to at least partially offset a gravitational force acting on the arm as the user moves and the arm support follows the movement of the user's arm. Alternatively, the exoskeletons may be permanently mounted to the harnesses.
1 . A fall-protection harness for removably carrying an exoskeleton when worn by a user, comprising:
a pair of leg loops configured to be received around respective thighs of the user;
a back panel configured to be positioned against the user's back when the harness is worn;
one or more attachment rings for connecting to a lanyard or other structure;
a plurality of front straps extending from the back panel and attached to the leg loops, the front straps having a length such that the front straps extend over shoulders of the user to the leg loops when the harness is worn;
a plurality of back straps extending from the back panel and attached to the leg loops such that the back straps extend along the user's back when the harness is worn; and
one or more connectors for engaging one or more respective connectors on an exoskeleton to couple the exoskeleton to the harness.
2 . The harness of claim 1 , wherein the one or more connectors comprise a back connector on the back panel for engaging a corresponding connector on a back strut of the exoskeleton.
3 . The harness of claim 2 , wherein the one or more attachment rings comprise a D-ring permanently attached to the back panel and wherein the back connector is attached to the back panel immediately below the D-ring.
4 . The harness of claim 1 , further comprising a waist belt attached to one or both of the front straps and the back straps such that the waist belt extends around the user's waist or hips when the harness is worn, and wherein the one or more connectors comprise one or more hip connectors on the waist belt for engaging corresponding connectors on a belt strut of the exoskeleton.
5 . The harness of claim 1 , wherein the one or more connectors comprise hip connectors on the front straps for engaging corresponding connectors on a belt strut of the exoskeleton.
6 . The harness of claim 1 , wherein the one or more connectors comprise a funnel-shaped connector including an open upper end and a relatively narrow lower end into which a connector on the exoskeleton may be received.
7 . The harness of claim 6 , wherein the funnel-shaped connector includes a lock member that engages the connector on the exoskeleton when the connector is fully seated in the lower end to lock the connectors together.
8 . The harness of claim 7 , wherein the lock member is movable relative to the lower end to allow a user to disengage the connector on the exoskeleton from an opening in the funnel-shaped connector to release the connectors.
9 . The harness of claim 7 , wherein the lock member comprises a snap fitting.
10 . The harness of claim 6 , wherein the funnel-shaped connector comprises guides extending from the upper end to the lower end to guide the connector from the exoskeleton into a recess in the lower end.
11 . The harness of claim 10 , wherein the funnel-shaped connector further comprises a ramped tab extending along an upper edge of the upper end to guide the connector from the exoskeleton into the guides.
12 - 23 . (canceled)
24 . A system for supporting an arm of a user, comprising:
a harness configured to be worn on a body of a user;
an exoskeleton comprising an arm support including an arm rest for receiving the arm of the user and one or more compensation elements configured to apply an offset force to at least partially offset a gravitational force acting on the arm as the user moves and the arm support follows the movement of the user's arm; and
one or more cooperating connectors on the harness and exoskeleton for removably mounting the exoskeleton to the harness, each cooperating connector comprising:
an exoskeleton connector on the exoskeleton; and
a harness connector on the harness comprising an open upper end, a relatively narrow lower end defining a recess into which the exoskeleton connector may be received, guides extending from the upper end to the lower end to guide the exoskeleton connector into a recess, and a lock member that engages the exoskeleton connector when fully seated in the lower end to lock the cooperating connectors together.
25 . The system of claim 24 , wherein the exoskeleton connector comprises a tab including a shaft and an enlarged head, the shaft sized to be slidably received between the guides the recess, the head sized to be seated in the recess and engage the lock member.
26 . The system of claim 24 , wherein the one or more cooperating connectors comprise a back connector on the back panel, and a pair of hip connectors at locations on the harness corresponding to the user's hips when the harness is worn.
27 . The system of claim 26 , wherein each of the hip connectors are adjustable relative the waist belt.
28 . The system of claim 26 , wherein the back connector is attached to a back panel of the harness immediately below an attachment ring.
29 . The system of claim 26 , wherein the one or more cooperating connectors comprise a first tab coupled to a spine strut on the exoskeleton located to be received in the back connector.
30 . The system of claim 29 , wherein the one or more cooperating connectors further comprise hip tabs on a hip strut on the exoskeleton configured to be received in the hip connectors.
31 . The system of claim 24 , wherein the lock member is movable relative to the lower end to allow a user to disengage the snap fitting from the opening to release the connectors.
32 - 33 . (canceled)
34 . A method for coupling an exoskeleton to a fall-protection harness, comprising:
donning the fall-protection harness;
positioning the exoskeleton such that a back connector tab on a spine strut of the exoskeleton is located adjacent a funnel-shaped harness connector on a back panel of the harness;
lowering the exoskeleton relative to the harness to direct the back connector tab into the funnel-shaped harness connector; and
directing hip connector tabs on a hip strut of the exoskeleton into corresponding funnel-shaped harness connectors at hip locations on the harness.
