Patent ID: 7819042

Claim:
A tensioning tool for use in tensioning an emergency brake cable system for a vehicle, the tensioning tool being driven by a rotational driver, and the emergency brake cable system including a cable end, the tensioning tool comprising: a main body; a plurality of components movably positioned in said main body to move between a first position and a second position and configured to selectively receive and engage the cable end; a bias member associated with the plurality of components and configured to bias the plurality of components to the first position; a first locking mechanism associated with the plurality of components and selectively actuable between a locked and unlocked engagement with the plurality of components; a release mechanism associated with said main body and the first locking mechanism, said release mechanism actuable to unlock said first locking mechanism from said plurality of components by moving the release mechanism relative to the main body; and the main body, the plurality of components, the bias member, the first locking mechanism and the release mechanism are configured such that: when the plurality of components are moved from the first position to the second position, the first locking mechanism actuates into locked engagement with the plurality of components to prevent the plurality of components from moving from the second position to the first position; and when the plurality of components are positioned at the second position and the release mechanism is actuated to unlock the first locking mechanism from the plurality of components by moving the release mechanism relative to the main body, the bias member moves the plurality of components from the second position to the first position.
