  • Patent number: 12012173
    Abstract: A tilt-decoupled steering device of a motorbike includes a handlebar bridge for receiving a motorbike handlebar, a fork bridge for receiving a fork leg, and at least one decoupling device connecting the handlebar bridge to the fork bridge. The handlebar bridge is mounted such that it can rotate about a steering axis and is secured about a tilt axis orthogonal to the steering axis, and the fork bridge is mounted such that it can rotate about the steering axis and about the tilt axis. The decoupling device transfers a steering movement and a steering torque in a steering direction about the steering axis between the handlebar bridge and the fork bridge, and compensates for a tilting movement in a tilting direction about the tilt axis of the fork bridge relative to the handlebar bridge.

    Abstract: A tilt-decoupled steering device of a motorbike includes a handlebar bridge which receives a handlebar, a fork bridge which receives a fork leg, and a decoupling element connecting the handlebar bridge to the fork bridge. The handlebar bridge (11) is rotatable about a steering axis and is secured about a tilt axis orthogonal to the steering axis. The fork bridge is rotatable about the steering axis and about the tilt axis. The decoupling element is elastic and is designed to transfer a steering movement in a steering direction about the steering axis from the handlebar bridge to the fork bridge, and to compensate for a tilting movement in a tilting direction about the tilt axis of the fork bridge relative to the handlebar bridge via elastic deformation.

  • Patent number: 11192650
    Abstract: An overhead stowage compartment of a passenger aircraft includes a carrier and a pivoting part being pivotable about a pivot axis and rotatable in a pivoting range at least between an open position and a closing position. A resetting device brings about a closing force in the direction of the closing position at a gripping point of the pivoting part. The closing force is greater than and opposed to the gravitational force, which is effective at the gripping point, by using the unloaded pivoting part. The stowage compartment has a holding device through the use of which the pivoting part can be held at the open position.
