Abstract
The invention relates to an apparatus for adjusting a seat position for a vehicle seat, which comprises at least one support element for a seat part and can be connected to a seat substructure, wherein the apparatus comprises at least one first limb and at least one second limb, wherein the limbs can be rotatably arranged on the seat substructure and the at least one support element, wherein a first angle α between the first limb and the support element can be adjusted by an angle adjustment device, wherein the at least one first limb and the at least one second limb each have a lever portion, and these are mechanically coupled, and wherein a change in the angle α causes a displacement of the at least one support element along a height axis Z, and a change in an angle of inclination θ of the support element.
Claims18
An apparatus for adjusting a seat position for a vehicle seat, the apparatus comprising:
- at least one support element for a seat part that can be connected to a seat substructure;
- and
- at least one first limb and at least one second limb,
- wherein the at least one first limb and the at least one second limb can be rotatably arranged on the seat substructure and the at least one support element,
- wherein a first angle between the first limb and the at least one support element can be adjusted by an angle adjustment device,
- wherein the at least one first limb has a first lever portion and the at least one second limb has a second lever portion,
- wherein the first lever portion forms a mechanical coupling with the second lever portion,
- wherein a change in the first angle causes a displacement of the at least one support element along a height direction,
- wherein the change in the first angle causes a change in an angle of inclination of the support element, and
- wherein a front portion of the vehicle seat and a rear portion of the vehicle seat both move along the height direction in a first direction when the first angle is changed,
- wherein the mechanical coupling comprises:
- a connecting element that connects the first lever portion to the second lever portion,
- wherein the change in the angle of inclination is caused by at least one of a different length of the lever portions of the at least one first limb and the at least one second limb or by a modification of a length of the connecting element,
- wherein the second lever portion has a greater length than the first lever portion,
- wherein the change in the first angle causes a displacement of the at least one support element along a longitudinal axis,
- wherein, when the change in the first angle causes a displacement of the at least one support element downwards along the height direction, the change in the first angle also, at the same time, causes a displacement of the at least one support element forwards along the longitudinal axis and a change in the angle of inclination in a negative direction, and
- wherein, when the change in the first angle causes a displacement of the at least one support element upwards along the height direction, the change in the first angle also, at the same time, causes a displacement of the at least one support element rearwards along the longitudinal axis and a change in the angle of inclination in a positive direction.
