ABSTRACT:
A safety device for restraining a person who works at great heights. The device comprises a housing, a drum rotatably mounted and contained within the housing, and a lifeline having a first end attached to the drum, and a second end extending outside the housing and adapted to be connected to a restraint. The lifeline is wound around the drum in response to the drum being rotated in a restraining direction, and the lifeline is unwound from around the drum in response to the drum being rotated in an opposite extending direction. The device also includes a spring for biasing the drum to rotate in the retracting direction, and a brake for braking extending rotation of the drum at an angular velocity in excess of some predetermined speed. When the person wears a body harness having crossed safety straps on one of the person's chest or back, the device further includes an attaching plate for slidably connecting the crossed straps to the housing.
