Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
123 words
A method for fabricating an actuating linkage assembly having a connecting link with two spaced pivot provisions with a tolerance compensating manufacturing system comprising the steps of prefabricating linkage components other than one pivot provision in said link the variable location of which can compensate for composite tolerance variations in the assembled components, preassembling said components on a fixture having locating means for positioning said assembly at a manufacturing station for establishing said one pivot location, locating said assembled components including said link at said station in required final assembled relation, establishing said one pivot provision in said link while said assembled components are located and held in said required relation, and completing said final assembly with said assembly located one pivot provision.
Claim 2
Independent Claim
123 words
A method for fabricating an actuating linkage assembly having a connecting link with two spaced pivot provisions with a tolerance compensating manufacturing system comprising the steps of prefabricating linkage components other than one pivot provision in said link the variable location of which can compensate for composite tolerance variations in the assembled components, preassembling said components on a fixture having locating means for positioning said assembly at a manufacturing station for establishing said one pivot location, locating said assembled components including said link at said station in required final assembled relation, establishing said one pivot provision in said link while said assembled components are located and held in said required relation, and completing said final assembly with said assembly located one pivot provision.
Claim 3
Dependent Claim
28 words
In the method set forth in claim 1 placing said fixture on a pallet means for transport positioning and holding a seat back adjuster assembly at said station.
Claim 4
Dependent Claim
29 words
In the method set forth in claim 2 providing free fit loading of the seat mounting bracket of said assembly on said fixture for final positioning through station tooling.
Claim 5
Dependent Claim
26 words
In the method set forth in claim 3 providing station tooling means for precisely locating components of said assembly relative to said required one pivot location.
Claim 6
Dependent Claim
20 words
In the method set forth in claim 4 providing station means for establishing effective location of said one pivot provision.
Claim 7
Dependent Claim
16 words
In the method set forth in claim 5 providing said station means with a hole punch.
Claim 8
Dependent Claim
27 words
In the method set forth in claim 6 providing said station means with a female die including support means for engaging said link during hole punching operation.
Claim 9
Dependent Claim
28 words
In the method set forth in claim 3 providing clearance in said pallet and mounting bracket accommodating die passage to supportingly engage said link for said punching operation.
