Abstract
Official abstract text for this publication.
The invention relates to a motor vehicle seat with a seat inclination adjustment device, with a first base element, a first seat frame element and a first actuator element, wherein the actuator element has a lower link arm connected to the base element via a lower link and movably arranged relative to the base element, an upper link arm connected to the lower link arm via a middle link and movably arranged relative to the lower link arm, wherein the upper link arm is connected to the seat frame element via an upper link and is arranged movably, and an inclination adjustment fitting with a first and a second fitting part, and wherein the inclination adjustment fitting is arranged on one of the links.
First claim
Opening claim text (preview).
The invention claimed is: 1. A motor vehicle seat with a seat inclination adjustment device, with a first base element, a first seat frame element, and a first actuator element, wherein the actuator element has a lower link arm which is connected to the base element via a lower link and is movably arranged relative to the base element, has an upper link arm which is connected to the lower link arm via a middle link and is movably arranged relative to the lower link arm, wherein the upper link arm is connected to the seat frame element via an upper link and is movably arranged, and has an inclination adjustment fitting with a first fitting part and a second fitting part, wherein the inclination adjustment fitting is arranged on one of the links characterized in that the seat inclination adjustment device has a motor and the inclination adjustment fitting can be driven by a motor characterized in that the seat inclination adjustment device has a second actuator element and the two actuator elements each have a separate motor. 2. The motor vehicle seat with a seat inclination adjustment device according to claim 1 characterized in that the upper link is arranged on the front side of the seat frame element. 3. The motor vehicle seat with a seat inclination adjustment device according to claim 1 characterized in that the inclination adjustment fitting is arranged on the lower link. 4. The motor vehicle seat with a seat inclination adjustment device according to claim 1 characterized in that the motor is a geared motor. 5. The motor vehicle seat with a seat inclination adjustment device according to claim 4 characterized in that the motor is arranged on the base element. 6. The motor vehicle seat with a seat inclination adjustment device according to claim 1 characterized in that the inclination adjustment fitting is arranged in the force flow of a force which acts on the motor vehicle seat in the event of a (frontal) crash. 7. The motor vehicle seat with a seat inclination adjustment device according to claim 1 characterized in that the first actuator element is arranged on the right side and the second actuator element on the left side of the seat. 8. The motor vehicle seat with a seat inclination adjustment device according to claim 1 characterized in that the inclination adjustment fitting of the first actuator element and the inclination adjustment fitting of the second actuator element are connected via a shaft. 9. The motor vehicle seat with a seat inclination adjustment device according to claim 1 characterized in that the first fitting part is pivotably connected to the second fitting part. 10. The motor vehicle seat with a seat inclination adjustment device according to claim 1 characterized in that the first fitting part has internal teeth and the second fitting part has external teeth. 11. A method for adjusting the seat inclination of a motor vehicle seat having a base element, a lower link arm which is connected to the base element via a lower link and is movably arranged relative to the base element, an upper link arm which is connected to the lower link arm via a middle link and is movably arranged relative to the lower link arm, a seat frame element which is connected to the upper link arm via an upper link and is movably arranged with respect to the upper link arm, an inclination adjustment fitting with a first fitting part and a second fitting part, wherein the inclination adjustment fitting is arranged on one of the links characterized in that the inclination adjustment fitting is driven by a motor; and the first fitting part is fastened to the base element and the second fitting part is fastened to the lower link arm. 12. The method for adjusting the seat inclination of a motor vehicle seat according to claim 11 characterized in that the first fitting part is fastened to a link arm or to the base element or to the seat frame and the second fitting part is fastened to a link arm which is different with respect to the first fitting part. 13. The method for adjusting the seat inclination of a motor vehicle seat according to claim 11 characterized in that in the event of a (frontal) crash, the force flow of the forces acting on the motor vehicle seat is routed through the inclination adjustment fitting. 14. A motor vehicle seat with a seat inclination adjustment device, with a first base element, a first seat frame element, and a first actuator element, wherein the actuator element has a lower link arm which is connected to the base element via a lower link and is movably arranged relative to the base element, has an upper link arm which is connected to the lower link arm via a middle link and is movably arranged relative to the lower link arm, wherein the upper link arm is connected to the seat frame element via an upper link and is movably arranged, and has an inclination adjustment fitting with a first fitting part and a second fitting part, wherein the inclination adjustment fitting is arranged on one of the links characterized in that the seat inclination adjustment device has a motor and the inclination adjustment fitting can be driven by a motor characterized in that the first fitting part is fastened to a link arm or to the base element or to the seat frame and the second fitting part is fastened to a link arm which is different with respect to the first fitting part and the first fitting part is fastened to the base element and the second fitting part is fastened to the lower link arm.
