1. A vibration damper system for a steering wheel arrangement of a motor vehicle, which is provided for arrangement on a steering wheel element of the steering wheel arrangement, comprising
a vibration damping mass for damping the vibration of the steering wheel arrangement,
an elastic bearing element which comprises a fastening element for fastening the elastic bearing element to the one of the steering wheel element and the vibration damping mass, and
a fastening means for fastening to the other of the steering wheel element and the vibration damping mass, wherein the elastic bearing element sectionally rests against the fastening means,
wherein the elastic bearing element comprises an annular bearing portion whose first side faces the one of the vibration damping mass and the steering wheel element and whose second side, which is disposed opposite the first side, faces the other of the vibration damping mass and the steering wheel element, wherein the fastening element is formed on the first side of the annular bearing portion,
wherein the fastening element comprises a plurality of pins which are arranged along the circumferential edge of the annular bearing portion and each protrude from the first side of the annular bearing portion along an axis from the annular bearing portion, wherein each pin has a protrusion directed radially to the outside with respect to the axis,
wherein in addition to the elastic bearing element a sleeve element is provided, which extends along a main axis of extension of the sleeve element and which includes an annular bearing portion that extends in a plane perpendicular to the main axis of extension of the sleeve element and that has a first side and a second side opposite the first side,
wherein in the intended state the first side of the annular bearing portion of the sleeve element rests against the second side of the annular bearing portion of the elastic bearing element,
wherein the pins of the elastic bearing element protrude beyond a central cylindrical portion of the sleeve element,
wherein a compressive force exerted on the steering wheel element to be fastened or the vibration damping mass to be fastened by the annular bearing portion of the elastic bearing element and by the radially outwardly directed protrusions of the elastic bearing element can be adjusted by the fastening means,
wherein on the second side of the annular bearing portion of the sleeve element there is provided a receptacle for a spring element, with one or more pins inside the receptacle for fixing the spring element.
2. The vibration damper system according to claim 1 , wherein in the intended state the elastic bearing element on the one hand rests against the first side of the annular bearing portion of the sleeve element and on the other hand against the fastening means, wherein the elastic bearing element exerts a compressive force on the first side of the annular bearing portion of the sleeve element and on the fastening means.
3. The vibration damper system according to claim 1 , wherein the pins are configured to protrude through an opening in the vibration damping mass or the steering wheel element, and the protrusions directed radially to the outside are configured to engage behind the vibration damping mass or the steering wheel element.
4. The vibration damper system according to claim 1 , wherein in the intended state the sleeve element extending along the axis does not extend beyond the end of the pins of the elastic bearing element facing away from the annular bearing portion of the elastic bearing element.
5. The vibration damper system according to claim 2 , wherein the elastic bearing element can be fastened to the steering wheel element or to the vibration damping mass by clamping the steering wheel element or the vibration damping mass between the annular bearing portion of the elastic bearing element and the radially outwardly directed protrusions of the elastic bearing element.
6. The vibration damper system according to claim 1 , wherein the elastic bearing element includes an opening which is surrounded by the annular bearing portion and which forms a feed-through opening from the first side to the second side of the annular bearing portion.
7. The vibration damper system according to claim 6 , wherein in the intended state the sleeve element extends along the axis and protrudes through the opening of the elastic bearing element.
8. The vibration damper system according to claim 1 , wherein the elastic bearing element with its fastening element is manufactured in one piece from an elastic material.
9. The vibration damper system according to claim 1 , wherein the sleeve element is formed in one piece.
10. The vibration damper system according to claim 1 , wherein the vibration damper system comprises a spring element which in the intended state is arranged between the second side of the annular bearing portion of the sleeve element and the vibration damping mass or the steering wheel element.
