Abstract: A seat assembly in which a seat is mounted on a vibration damping mounting including a variable rate spring in the form of a fluid filled and pressurized pouch disposed between two rigid members capable of relative rotation, vertical movements of the seat which result in relative rotation of the two rigid members towards each other being arranged to compress the pouch and increase the area of contact of the pouch with the rigid members.

Abstract: A handle for an electrically-operated hand-held tool such as a hedge trimmer is formed with a body having similar terminals at its opposite axial ends. The handle body can make a plug-and-socket connection with the tool housing in any chosen one of a number of different positions angularly rotated or inverted relative to one another, terminals on the body and housing making contact in any of these positions. In this way the attitude of the handle relative to the tool can be varied without losing the electrical connection. In a modification the body is integral with one end of the pivotable extension adapted to carry a handle at its other end.
