  • Patent number: 10308262
    Abstract: 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.

  • Patent number: 10227077
    Abstract: A system includes a bearing bracket, for connecting a coupler rod or a connection rod to a car, and a coupler rod or a connection rod connected to the bearing bracket. The bearing bracket has an adapter and a joint that allows the adapter to swivel relative to the bracket. The rod has a stabilizing element having a surface that is not parallel to the longitudinal axis of the rod and is spaced apart from a surface of the bearing bracket. Upon application of a force of a predetermined first strength in one direction, the adapter moves relative to the bracket in the one direction until the surface of the stabilizing element contacts the surface of the bearing bracket. Upon application of a force of a second strength to the rod, the stabilizing element detaches from the rod, so that the rod can move relative to the stabilizing element.
