ABSTRACT:
A ceiling fan safety tether to be used with a conventional ceiling fan. The ceiling fan safety tether retains a fan blade in close proximity to the fan motor thereby preventing the fan blade from becoming a flying projectile should a break in a fan blade bracket ever occur. The ceiling fan safety tether comprises a body portion having a first and second securement coupled thereto. The first securement is secured to the fan motor housing and the second securement is secured to the fan blade. The ceiling fan safety tether is designed to be interposed between the fan blade bracket and the fan motor housing at a first end and interposed at a second end between the fan blade and the fan blade bracket. Additionally, the ceiling fan safety tether serves to provide a dampening effect that prevents noise and vibrations created in the fan motor housing from being transmitted to the fan blade.
