  • Telescoping seat assembly for a construction vehicle
    Patent number: 6814174
    Abstract: A seat assembly is for a construction vehicle, preferably a compacting vehicle, and includes a base attached to the vehicle and having an axis and a rail movably connected with the base so as to be angularly displaceable about the base axis. The rail has a longitudinal centerline extending generally perpendicularly with respect to the base axis. A seat carriage is movably connected with the rail so as to be linearly displaceable along the rail centerline. A linkage is connected with the base and with the seat carriage and is configured to linearly displace the carriage along the rail centerline when the rail angularly displaces about the base axis, preferably between a most proximal position with respect to the base axis and a most distal position with respect to the axis. Preferably, the linkage includes a cam connected with the base and a follower connected with the carriage.
