Abstract

An energy absorber assembly for use with a safety harness comprises a connector, a bracket assembly, a fastener, and an energy absorber. The connector is configured and arranged to operatively connect to the safety harness. The fastener operatively connects the bracket assembly and the connector, and the fastener releases the bracket assembly from the connector when subjected to a predetermined load. The energy absorber operatively connects the bracket assembly and the connector, and the energy absorber includes a first portion and a second portion that separate to absorb shock after the bracket assembly is released from the connector.

First claim

The invention claimed is:

1. An energy absorber assembly for use with a safety harness and a lifeline, the energy absorber assembly comprising:
a connector configured and arranged to operatively connect directly to the safety harness;
a bracket assembly including a base having a swivel connector, the swivel connector configured and arranged to operatively connect to the lifeline;
a fastener directly connecting the bracket assembly and the connector, the base being pivotable with respect to the fastener relative to the connector, the fastener configured to release the bracket assembly from the connector when the bracket assembly is subjected to a predetermined load; and
an energy absorber interconnecting the bracket assembly and the connector, the energy absorber including a first portion and a second portion configured to separate to absorb shock after the bracket assembly is released from the connector.

2. The energy absorber assembly of claim 1 , wherein the bracket assembly comprises:
a bracket base having a slot forming a tab portion with an aperture and a bar portion, the aperture configured and arranged to receive the fastener, the bar portion configured and arranged to be engaged by the energy absorber.

3. The energy absorber assembly of claim 1 , further comprising at least one protrusion extending outward from the connector configured to limit rotation of the base relative to the connector.

4. The energy absorber assembly of claim 1 , wherein the bracket assembly is configured and arranged to be operatively connected to the lifeline which includes a first lifeline and a second lifeline.

5. The energy absorber assembly of claim 4 , wherein the bracket assembly comprises:
the base including a first base and a second base, the swivel connector including a first swivel connector and a second swivel connector;
the first base having a first base aperture and a first lifeline connector operatively connected to the first swivel connector, the first lifeline connector being configured and arranged to engage the first lifeline;
the second base having a second base aperture and a second lifeline connector operatively connected to the second swivel connector
the second lifeline connector being configured and arranged to engage the second lifeline;
a base connector having a plate portion with a base connector aperture and a flange, the base connector being configured and arranged to extend through the first and second base apertures, the base connector aperture configured and arranged to receive the fastener, the flange configured to prevent the first and second bases from sliding off the base connector, the first and second bases being configured and arranged to be engaged by the energy absorber.

6. The energy absorber assembly of claim 1 , wherein the energy absorber has an upside down V-shaped configuration.

7. The energy absorber assembly of claim 6 , in combination with the safety harness, further comprising a cover interconnecting the energy absorber and the safety harness.

8. The energy absorber assembly of claim 7 , wherein the cover has a top portion configured and arranged to releasably engage the bracket assembly, a first leg configured and arranged to releasably engage a first strap of the safety harness, and a second leg configured and arranged to releasably engage a second strap of the safety harness.

9. An energy absorber assembly for use with a safety harness and a lifeline, the energy absorber assembly comprising:
a fastener;
a connector configured and arranged to operatively connect directly to the safety harness;
a bracket assembly including a base and at least one swivel connector portion, the base having an aperture, the aperture configured and arranged to receive the fastener, the base configured and arranged to be engaged by an energy absorber, the at least one swivel connector portion being configured and arranged to engage the lifeline, the fastener operatively connecting the base and the connector, the bracket assembly being pivotable with respect to the fastener relative to the connector, the fastener configured to release the bracket assembly from the connector when the bracket assembly is subjected to a predetermined load; and
the energy absorber assembly further comprising the energy absorber interconnecting the bracket assembly and the connector, the energy absorber including a first portion and a second portion configured to separate to absorb shock after the bracket assembly is released from the connector.

10. The energy absorber assembly of claim 9 , further comprising at least one protrusion extending outward from the connector configured to limit rotation of the bracket assembly relative to the connector.

11. The energy absorber assembly of claim 9 , wherein the lifeline comprises a first lifeline and a second lifeline, and wherein the bracket assembly comprises:
the base including a first base portion, a second base portion, and a base connector;
the first base portion having a first base aperture and a first lifeline connector operatively connected to a first one of the at least one swivel connector portion, the first lifeline connector being configured and arranged to engage the first lifeline;
the second base portion having a second base aperture and a second lifeline connector operatively connected to a second one of the at least one swivel connector portion, the second lifeline connector being configured and arranged to engage the second lifeline; and
the base connector having a plate portion with the aperture and a flange, the base connector being configured and arranged to extend through the first and second base apertures, the flange and the connector configured to prevent the first and second base portions from sliding off the base connector, the first and second base portions configured and arranged to be engaged by the energy absorber.

12. The energy absorber assembly of claim 9 , wherein the energy absorber has an upside down V-shaped configuration.

13. The energy absorber assembly of claim 12 in combination with the safety harness, further comprising a cover interconnecting the energy absorber and the safety harness.

14. The energy absorber assembly of claim 13 in combination with the safety harness, wherein the cover has a top portion configured and arranged to releasably engage the bracket assembly, a first leg configured and arranged to releasably engage a first strap of the safety harness, and a second leg configured and arranged to releasably engage a second strap of the safety harness.

15. An energy absorber assembly for use with a safety harness and a first and second lifelines, the energy absorber assembly comprising:
a connector configured and arranged to operatively connect directly to the safety harness,
a bracket assembly comprising:
a first base comprising a first swivel connector configured and arranged to be operatively connected to the first lifeline,
a second base comprising a second swivel connector configured and arranged to be operatively connected to the second lifeline, and
a base connector,
the first and second bases being pivotable relative to the connector;

a fastener directly connecting the connector and the bracket assembly, the first and second bases being pivotable with respect to the fastener relative to the connector, the fastener configured to release the bracket assembly and the first and second lifelines from the connector when the bracket assembly is subjected to a predetermined load; and
an energy absorber interconnecting the bracket assembly and the connector, the energy absorber including a first portion and
