Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
128 words
A seat assembly for use on a vehicle having a pair of spaced control stations, comprising: a seat means for supporting an operator; a support means pivotally mounted at one end to the vehicle and rotatably supporting the seat means at the other end; said support means being arranged to be pivotable between a first position in which the seat means is adjacent one of said stations and a second position adjacent the other of said stations; and a cable means means operatively connected between the seat means and the vehicle and responsive to manual pivoting of said support means between its first and second positions to rotate the seat the proper distance on said support means so that an operator therein is facing the adjacent control station.
Claim 2
Dependent Claim
128 words
A seat assembly for use on a vehicle having a pair of spaced control stations, comprising: a seat means for supporting an operator; a support means pivotally mounted at one end to the vehicle and rotatably supporting the seat means at the other end; said support means being arranged to be pivotable between a first position in which the seat means is adjacent one of said stations and a second position adjacent the other of said stations; and a cable means means operatively connected between the seat means and the vehicle and responsive to manual pivoting of said support means between its first and second positions to rotate the seat the proper distance on said support means so that an operator therein is facing the adjacent control station.
