Abstract
The invention relates to a device 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, the device comprising at least one first leg and at least one second leg, the legs being rotatably arrangeable on the seat substructure and the at least one support element, the at least one first leg and the at least one second leg being mechanically coupled by a connecting element, the length of which can be modified, wherein a modification of the length of the connecting element causes a change in an angle of inclination θ of the support element.
Claims17
A device for adjusting a seat position for a vehicle seat, the device comprising at least one support element for a seat part and that can be connected to a seat substructure,
- wherein the device comprises at least one first leg and at least one second leg, wherein the at least one first leg and the at least one second leg can be rotatably arranged on the seat substructure and the at least one support element, wherein the at least one first leg and the at least one second leg are mechanically coupled by a connecting element, a length of which is modifiable, wherein a modification of the length of the connecting element causes a change in an angle of inclination of the support element, wherein the at least one first leg is mounted to a first axis of rotation relative to the seat substructure, wherein the at least one second leg is mounted to a second axis of rotation relative to the seat substructure, wherein a distance between the first axis of rotation and the second axis of rotation is fixed, wherein the at least one first leg and the at least one second leg are each rotatably mounted about an axis of rotation relative to the support element, wherein, in an upper end region of a first section, the axis of rotation is arranged with respect to the rotation relative to the support element, wherein the axis of rotation with respect to the rotation relative to the seat substructure is arranged in a bend region, and wherein the modification of the length of the connecting element causes a rotation of the at least one second leg about at least the axis of rotation with respect to a rotation relative to the connecting element and about the axis of rotation with respect to a rotation relative to the seat substructure, with the modification of the length of the connecting element not causing any rotation of the at least one first leg.
A device for adjusting a seat position for a vehicle seat, the device comprising:
- a support element for a seat part, the support element capable of being connected to a seat substructure of the vehicle seat;
- a first leg rotatably arranged on the seat substructure and the support element;
- a second leg rotatably arranged on the seat substructure and the support element;
- and
- a connecting element that mechanically couples the first leg and the second leg, wherein a length of the connecting element is modifiable,
- wherein an extension of the connecting element causes a positive change in an angle of inclination of the support element, wherein a contraction of the connection element causes a negative change in the angle of inclination of the support element,
- wherein the angle of inclination extends between a central axis of the support element and a reference axis that is substantially parallel to a longitudinal axis of the device, wherein the angle of inclination is proportional to the length of the connecting element,
- wherein the first leg and the support element enclose a first angle that is adjustable by an angle adjustment device, wherein a change in the first angle that causes a downward displacement of the support element along a height axis also causes a forward displacement of the support element along the longitudinal axis, and wherein a change in the first angle that causes an upward displacement of the support element along the height axis also causes a backward displacement of the support element along the longitudinal axis.
A device for adjusting a seat position for a vehicle seat, the device comprising at least one support element for a seat part and that can be connected to a seat substructure,
- wherein the device comprises at least one first leg and at least one second leg, wherein the at least one first leg and the at least one second leg can be rotatably arranged on the seat substructure and the at least one support element, wherein the at least one first leg and the at least one second leg are mechanically coupled by a connecting element, a length of which is modifiable, wherein a modification of the length of the connecting element causes a change in an angle of inclination of the support element, wherein the at least one first leg is mounted to a first axis of rotation relative to the seat substructure, wherein the at least one second leg is mounted to a second axis of rotation relative to the seat substructure, wherein a distance between the first axis of rotation and the second axis of rotation is fixed, wherein the at least one second leg is indirectly connected to the at least one support element, the at least one second leg being connected to the support element via a spacing element, wherein the spacing element is rotatable about an axis of rotation relative to the at least one second leg, and wherein the spacing element is rotatable about a further axis of rotation relative to the support element.
