Problems solved by technology

[0003] However, when a heavy driver sits on the vehicle seat and wishes to adjust the extension force according to his weight, he must significantly increase the initial tension of the spring, which means a substantial application of force and therefore does not provide quick adjustment

Abstract

A suspension device (1) for a vehicle seat (2), comprising an upper suspension part (3) and a lower suspension part (4), the upper suspension part (3) and the lower suspension part (4) pass through a first The rotary link (5) and the second rotary link (6) are interconnected, wherein the suspension device (1) comprises a first adjustable gear element (7), a second gear element (8) and a third gear element ( 9), wherein the first adjustable gear element (7) is arranged on said upper suspension part (3), said second gear element (8) is connected to the first rotary link (5) and is used to adjust the first spring The position of the unit (10), and by adjusting the position of the first spring unit (10), the spring force and spring rate of the suspension device can be changed, wherein the third gear element (9) is at least effectively connected to the first and the first Two gear elements (7, 8) are connected to the first rotary connection (5).

Description

technical field [0001] The invention relates to a suspension device, in particular for a vehicle seat, comprising an upper suspension part and a lower suspension part, which can be connected to each other by a first rotary connection and a second rotary connection. Background technique [0002] Such suspension devices for vehicle seats are known from the prior art, in which the upper suspension part, the lower suspension part, the first and the second swivel connection form a parallelogram, so that even in the case of spring movement , the upper hanging part is also parallel to the lower hanging part. For the suspension of the vehicle seat, the suspension device preferably comprises a spring, wherein the extension force of the suspension device can be adjusted by tensioning the spring. [0003] However, when a relatively heavy driver sits on the vehicle seat and wishes to adjust the extension force according to his body weight, he must significantly increase the initial ten...
