Abstract
Official abstract text for this publication.
A vehicle seat has a seat base element, a seat back and a headrest that has a headrest mount connected or connectable to the seat back. The headrest mount is connected to an inner headrest structure. At least one mechanical or electromechanical active element is located in the headrest. The active element is fastened to the headrest structure or to the headrest mount by way of at least one elastic mounting element.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A vehicle seat, comprising: a seat base element; a backrest; and a headrest having an inner headrest structure and a headrest mount, the headrest mount defining a plane, and being connectable to the backrest, and being connected to the inner headrest structure; at least one mechanical or electromechanical active element contained in the headrest, wherein the active element has an independent active functionality and does not serve as a dead mass exclusively for vibration damping, and wherein the active element is fastened to and spaced perpendicular and forward of the plane defined by the headrest mount in an elastically suspended manner by way of at least one elastic mount element projecting in a forward direction, and forms an oscillating mass which damps externally excited vibrations of the headrest. 2 . The vehicle seat according to claim 1 , wherein the active element is a loudspeaker. 3 . A vehicle comprising at least one vehicle seat according to claim 1 . 4 . A headrest assembly, comprising: a headrest having an inner headrest structure and a headrest mount, the headrest mount defining a plane, and being connectable to a backrest, and being connected to the inner headrest structure; at least one mechanical or electromechanical active element contained in the headrest, wherein the active element has an independent active functionality and does not serve as a dead mass exclusively for vibration damping, and wherein the active element is fastened to and spaced perpendicular and forward of the plane defined by the headrest mount in an elastically suspended manner by way of at least one elastic mount element projecting in a forward direction, and forms an oscillating mass which damps externally excited vibrations of the headrest. 5 . The headrest assembly according to claim 4 , wherein an entirety of the active element is positioned forward of the plane defined by the headrest mount. 6 . The vehicle seat according to claim 1 , wherein an entirety of the active element is positioned forward of the plane defined by the headrest mount.
