Suspension device
First Claim
1. A suspension device for a vehicle seat, comprising:
- an upper suspension portion and a lower suspension portion, which are interconnected by a first swivel connector and a second swivel connector, and the first swivel connector and the second swivel connector are each configured to be pivoted about a swivel pin in response to an oscillating movement of the upper suspension portion relative to the lower suspension portion,wherein a first toothed wheel element which is rotatable about a first axis of rotation is arranged on the first swivel connector, the first toothed wheel element being in operative contact with a second toothed wheel element which is rotatable about a second axis of rotation, wherein rotation of the second toothed wheel element rotates the first toothed wheel element, which adjusts a position of a first spring unit to change a spring force of the suspension device,wherein a first end region of the first spring unit is connected to an adjustment device which is connected to the first swivel connector and rotatable about the first axis of rotation, and a second end region of the first spring unit is connected to the lower suspension portion.
