Abstract: A device for deflecting a tire of a motor vehicle when the tire is pushed accidentally into the device has a deflection plate for mounting fixedly on the motor vehicle. An outer face of the deflection plate is substantially vertical, faces the tire of the motor vehicle at a distance from the tire sufficient not to interfere with normal operation of the tire on the motor vehicle but effective to engage the tire when the tire is pushed accidentally and is inclined at an angle to a longitudinal vertical plane of the motor vehicle. A coating or sliding shield on the outer face of the deflection plate facilitates sliding of the tire along the incline of the outer face when the tire is pushed accidentally to engage the outer face of the deflection plate.

Abstract: A deformable safety barrier placed along a roadside, the barrier being constituted by metal section bars (11) assembled to one another by partial overlapping and by bolting, and supported at intervals by vertical posts, the bar section (11) having a central groove (1) with a rib (2) on either side thereof, the ribs projecting towards the road, each rib also having an outer flange (3a) extending away from the road, the barrier being characterized in that the outer flanges (3a) of the ribs (2) of the section extend beyond the vertical plane XX' tangential to the bottom of the central groove (1) by a distance lying between one-half and twice the distance between said vertical plane XX' and the points of the ribs (2) closest to the road.

Abstract: This invention relates to safety devices placed on the side of highways, of the barrier, rail or curb type, comprising a continuous strip parallel to the road and exposed to the shocks of the vehicles, intended for retaining the latter, which continuous strip bears a solid or pasty sliding coating, for example a coating of polytetrafluoroethylene or a solid silicone resin, or a layer of a paraffin wax or of micronized graphite, or a layer of grease.
