  • Cab for a motor-driven tractor vehicle
    Patent number: 7637557
    Abstract: A cab for a tractor vehicle is provided with side spoilers that form extensions of the side walls of the cab in a backward direction and that can pivot between a backward-directed position and a sideways-directed position in order to give access to the chassis space behind the cab. A step arrangement is mounted on the inside of one side spoiler in such a way that it can be moved between a raised position, in which it is concealed behind the side spoiler, when this is in its backward-directed position, and a lowered position, in which it has a part with steps located below the lower edge of the side spoiler.
