Vehicle seat with adjustment device
The invention relates to a vehicle seat with at least one laterally positioned operating device for operating the vehicle seat functions and/or vehicle functions and an adjustment device for adjusting a vertical position and/or an inclination of the at least one operating device with respect to a rest of the vehicle seat, wherein the adjustment device comprises a rotational axis extending in the seat width direction and a shaft which is connected to the operating device, positioned at a distance from the rotational axis and rotatable together with the operating device about the rotational axis, wherein the adjustment of the vertical position and/or of the inclination of the operating device is feasible by means of a rotational movement of a spindle element which is in operative contact with the shaft, wherein a central axis of the spindle element is perpendicular to a central axis of the shaft.
1. A vehicle seat, comprising:
at least one laterally positioned operating device for operating at least one of vehicle seat functions or vehicle functions; and
an adjustment device for adjusting at least one of a vertical position or an inclination of the at least one operating device with respect to a rest of the vehicle seat,
wherein the adjustment device comprises a rotational axis extending in the seat width direction and a shaft that is connected to the operating device, positioned at a distance from the rotational axis and rotatable together with the operating device about the rotational axis,
wherein the adjustment of at least one of the vertical position or of the inclination of the operating device includes a rotational movement of a spindle element of the adjustment device, which is in operative contact with the shaft,
wherein a central axis of the spindle element is arranged perpendicular to a central axis of the shaft,
wherein the adjustment device further comprises:
a slide element arranged at a first end of the spindle element;
a first lever element, wherein a first end of the first lever element is rotatably mounted to an axis of rotation located on a first end of the slide element, and wherein a second end of the first lever element is connected to the shaft;
a shaft element arranged in the seat width direction; and
a second lever element,
wherein a first end of the second lever element is rigidly connected to the shaft element, and
wherein the first end of the first lever element, the second end of the second lever element, and the first end of the slide element are joined at the axis of rotation.
2. The vehicle seat according to claim 1 , wherein a distance between the rotational axis and the shaft is permanently set and the rotational axis is positioned behind the shaft in the seat length direction.
3. The vehicle seat according to claim 1 , wherein an internal thread of the slide element is in operative contact with an external thread of the spindle element, so that the rotational movement of the spindle element is transmissible into a translational movement of the slide element.
4. The vehicle seat according to claim 1 , wherein a locking of the shaft is achievable by means of the interaction between an internal thread of the slide element and an external thread of the spindle element, wherein the adjustment device is provided free from an additional locking device for locking a position of the shaft with respect to the pivoting about the rotational axis.
5. The vehicle seat according to claim 1 , wherein the first end of the slide element is remote from the spindle element.
6. The vehicle seat according to claim 1 , wherein the shaft is movable within a slotted guide of a slotted guide element with respect to the pivoting about the rotational axis.
7. The vehicle seat according to claim 1 , wherein the second lever element is offset from the vehicle seat.
8. The vehicle seat according to claim 6 , wherein the slotted guide is shaped to extend along a portion of an arc, and wherein the arc is configured to extend concentrically with respect to the rotational axis.
9. A vehicle seat, comprising:
at least one laterally positioned operation device for operating at least one of vehicle seat functions or vehicle functions; and
an adjustment device for adjusting at least one of a vertical position or an inclination of the at least one operating device with respect to a remainder of the vehicle seat,
wherein the adjustment device comprises a rotational axis extending in the seat width direction and a shaft that is connected to the operating device, positioned at a distance from the rotational axis and rotatable together with the operating device about the rotational axis,
wherein the adjustment of at least one of the vertical position or of the inclination of the operating device includes a rotational movement of a spindle element of the adjustment device, which is in operative contact with the shaft, wherein a central axis of the spindle element is arranged perpendicular to a central axis of the shaft,
wherein the adjustment device further comprises:
a slide element arranged at a first end of the spindle element;
a first lever element, wherein a first end of the first lever element is rotatably mounted to an axis of rotation located on a first end of the slide element, and wherein a second end of the first lever element is connected to the shaft;
a shaft element arranged in the seat width direction; and
a second lever element,
wherein a first end of the second lever element is rigidly connected to the shaft element,
wherein the first end of the first lever element, the second end of the second lever element, and the first end of the slide element are joined at the axis of rotation,
wherein the shaft is moveable within a slotted guide of a slotted guide element with respect to the pivoting about the rotational axis, and
wherein a shape of the slotted guide is configured to extend along a portion of an arc.
