  • Patent number: 6398293
    Abstract: A cabin primarily intended for cross-country vehicles where the cabin is held up by a supporting device which includes a partially circular-shaped first bearing device lying in a vertical plane with the convex side facing downwards when the vehicle is standing horizontally. A base mounting plate attached to the vehicle's chassis is provided with a partially circular-shaped second bearing device that is equivalent to and interacting with this supporting device's bearing device, whereby the bearing device's common center forms a first axis of oscillation for the cabin in a first plane, and wherein the cabin is able to pivot about a second axis of oscillation that is perpendicular to the first axis of oscillation.

  • Patent number: 5368119
    Abstract: A cabin intended primarily for cross-country vehicles and supported at the top thereof by a carrier frame mounted on the vehicle.

The cabin is also connected to the carrier frame by means of shock absorbers which are spaced from the carrier device.
