Abstract: Flat-running device for fitting to a tubeless mounted assembly for a motor vehicle and a mounted assembly incorporating same is provided. The device is configured for a wheel rim (in several parts includes an annular supporting structure of the casing designed to be mounted around the rim and divided into sectors in an arc of a circle that are articulated together by connection members, and members for locking the beads against these edges which are designed to connect the annular supporting structure to these beads. The connection members including two spindles extending in the axial direction and respectively attached in two adjacent sectors and connected together by an articulation extending in the circumferential direction of the device, the articulation having a rigid lug with two through-holes or else a flexible link with two loops, the or the link being articulated on these spindles by these two holes or loops, respectively.

Abstract: The present invention relates to a flat-running device designed to be fitted to a tubeless mounted assembly for a motor vehicle and such a mounted assembly incorporating this device. A flat-running device according to the invention, for a wheel rim (in several parts includes an annular supporting structure of the casing which is designed to be mounted around the rim and which is divided into sectors in an arc of a circle that are articulated together by connection means, and means for locking the beads against these edges which are designed to connect said annular supporting structure to these beads.
