Bearing bracket, assembly containing such a bearing bracket and system containing such an assembly

An assembly has a bearing bracket and a coupler or connection rod. The bearing bracket has an adapter to which the rod can be connected. A joint allows the adapter to swivel relative to the bracket, and the rod is attached to the adapter. The rod has a surface that extends in a plane at an angle relative to the longitudinal axis of the rod. The rod surface is held spaced apart from a surface of the bearing bracket by an elastic element. The surface of the rod contacts the surface of the bearing bracket, if a pushing force of a predetermined strength is applied to the rod. A group of parts of the bearing bracket are connected to the bracket such that the parts are set free to move relative to the bracket, if a pushing force of a predetermined strength is applied to the rod.
