More Information
Summary:A vacuum cleaner nozzle (N) has a steering hinge arrangement (H1, H2) between a body (B) of the vacuum cleaner nozzle (N) and a connector (C) that is connectable to a unit having a handle, wherein thesteering hinge arrangement (H1, H2) comprises first (H1) and second (H2) steering hinges, the first steering hinge (H1) being operational until a first steering angle, and the second steering hinge (H2) being operational from the first steering angle, a transmission ratio of the second steering hinge (H2) exceeding a transmission ratio of the first steering hinge (H1). As a result, a transmissionratio of the steering hinge arrangement (H1, H2) increases with an increasing steering angle also when the unit is substantially flat. The first steering angle may be determined by edges (E) on the first steering hinge (H1) interacting with a protrusion (P) on the second steering hinge (H2). A force exercised by a spring (S) between the second steering hinge (H2) and the body (B) may hamper the second steering hinge (H2)
