A seat for a vehicle operator includes an occupant-supporting portion, a back and an armrest. The armrest is pivotable through a vertical plane between a horizontally extending, arm-supporting position and an upwardly extending position alongside the seat back. The armrest is also pivotable, in response to a predetermined outwardly directed force against the armrest, through a horizontal plane, between the above-described arm-supporting position and a position in which the armrest extends rearwardly from the seat back. Structure is provided which normally urges the armrest from its rearwardly extending position to a downwardly extending position alongside the seat.
