Operator's seat and controls arrangement for a tandem road roller
First Claim
1. Operator'"'"'s seat and controls arrangement for a tandem road roller with roller barrels comprising an operator'"'"'s platform with two operator'"'"'s seat (3,3'"'"'), two steering device (5) and a control stick (6), characterized in that(a) the operator'"'"'s seats (3,3'"'"') are mounted side by side for rotation substantially on the transverse center line of the operator'"'"'s platform and in the plane of the respective barrel edges,(b) the steering devices (5) are mounted on opposite transverse sides of the driver'"'"'s platform substantially on the longitudinal center plane of the operator'"'"'s platform and pivotable about an axis extending in said center plane such that each said steering device may be pivoted through said center plane to be accessible from either of said operator'"'"'s seats, and(c) said control stick (6) is arranged in the middle between the operator'"'"'s seats (3,3'"'"').

Abstract
An ergonomically advantageous operator'"'"'s seat and controls arrangement for tandem road rollers comprises on the transverse center line of an operator'"'"'s platform operator'"'"'s seats arranged side by side and rotatable about vertical axes. A control stick pivotable in two mutually orthogonal directions is located on the longitudinal center line of the operator'"'"'s platform in the middle between the operator'"'"'s seats. Two steering devices are mounted with their steering columns rotatable about a longitudinal, central axis on two opposite transverse sides of the platform. Thus by rotation of the seats through 180°, four possible seat positions for the operator are achieved. By pivoting the control stick towards the respective occupied seat and by corresponding rotation of one steering device to in front of this seat, all controls are always within easy reach of the operator. A step-down device is provided between the control stick and speed control means to permit sensitive adjustment of the travelling speed of the tandem road roller in low speed ranges.
