Abstract
An activation system includes a housing and a pulley mounted to the housing. The pulley is rotatable about an axis. An activation member is movable between a first position and a second position relative to the pulley to selectively couple to the pulley. When the activation member and the pulley are coupled, rotation of the pulley about the axis is restricted. A first tension member is operably coupled to the activation member and a first tension of the first tension member maintains the activation member in engagement with the pulley. At least one second tension member is wrapped about at least one of the pulley and the activation member and has a second tension acting on the at least one of the pulley and the activation member.
