ABSTRACT:
A mechanism for reliably adjusting and securing the load applied through a keeper and a tension latch assembly is provided. The mechanism includes a housing (25, 35), a drive system (50, 70) for effecting the adjustment, and a clutching arrangement (50, 60, 70, 80) within the housing which prevents the drive system from effecting any further adjustment when a pre-determined load is achieved between the keeper and the hook of the latch assembly. Other features include the placement of the driving component, accessed by the operator, at a location external to the housing and provision of audible and physical indicators for the benefit of the operator when the desired load adjustment has been accomplished.
