1. In a fastening system for installing fasteners by a worker, the combination comprising:
- a hand-held installation tool having a pistol-grip handle for manipulation and actuation of said tool and a stressrelieving device for relieving stress on the worker'"'"'s wrist, hand and fingers while the worker is holding said took, said pistolgrip handle having a hand-grip axis, said stress-relieving device comprising a platform adapted to supportably engage the worker'"'"'s forearm, and attaching means for attaching said platform to said tool so that said platform extends essentially normal to said hand grip axis, said platform being located in a plane passing through a lower portion of said handle so that said platform underlies the worker'"'"'s forearm when the worker'"'"'s hand is in gripping engagement with said handle, said platform comprises a U-shaped rod that includes a web portion located below said handle and two spaced arm portions extending from said web portion across and beyond said handle cross-sectional profile, and a panel member extending across the space between said arm portions for supporting the worker'"'"'s forearm, said panel member being made of a conformable material whereby said panel member can conform to the contour of the worker'"'"'s forearm, said attaching means comprises an adjustable clamping means including a band extendable around said handle at its lower end, said platform comprises a first connector element extending from said web portion alongside a first surface of said handle and a second connector element extending form said spaced arm portions alongside a second surface of said handle, said band of said clamping means being adapted to encircle said handle and said two connector elements for attaching said platform to said tool.

Abstract
An armrest attachable to a tool to provide support for a worker'"'"'s wrist while the tool is being manipulated or actuated. The armrest underlies the worker'"'"'s forearm so the weight of the tool is borne partly by the worker'"'"'s fingers and hand and partly by the worker'"'"'s forearm. Stress on the wrist is minimized and good wrist posture is maintained. Due to the location of the armrest, the worker'"'"'s forearm is located directly behind the tool handle where it can absorb kickback forces that occur as an incidental part of a lockbolt installation process.
