摘要:
A back pad system for use in connection with a safety harness which includes at least two spaced back straps and a connector adapted to be connected to a line or lanyard includes a back pad having passages through which the two back straps can be passed to be crossed over the connector, an attachment to which the connector can be moveably attached, and at least one member that captures the connector in an upright position upon application of force such as manual force (either directly or indirectly) to the connector to move the connector to the upright position. A back pad for use in connection with a safety harness includes at least two spaced back straps and a connector adapted to be connected to a line or lanyard. The back pad includes a base comprising passages through which the two back straps can be passed to be crossed over the connector and at least one load indicator. The load indicator includes an area of reduced strength in the base so that the area visibly distends or breaks upon the back pad being subjected for a substantial load. The substantial load can, for example, be predetermined to be at least approximately 450 pounds of force. The area of reduced strength can, for example, be an area of reduced thickness. The back pad can, for example, include a plurality of areas of reduced thickness.
