US 11,377,003 B2 · Suspension system, preferably driver seat

Abstract

The invention relates to a suspension system (1), preferably a driver seat (1), comprising a first suspension part (10), preferably a frame (10) of the driver seat (1); a second suspension part (11), preferably a seat surface (11) of the driver seat (1), wherein the two suspension parts (10, 11) are movable relative to each other in at least one first spatial direction (Z), preferably in the vertical direction (Z); a kinematic system (12), preferably a scissor kinematic system (12) which is designed to connect the two suspension parts (10, 11) in a movable manner relative to each other at least in the first spatial direction (Z); a suspension device (13) which is designed to support the static load of the second suspension part (11); and an actuator (2) which is designed to introduce a force bidirectionally between the two suspension parts (10, 11) and thereby actively damp the relative movement between the two suspension parts (10, 11). The suspension system (1) is characterized in that the actuator (2) has a bearing (28), preferably a ball bearing (28), which is arranged within the power flow between the two suspension parts (10, 11) such that an axial load can be kept away from the driven axle of the actuator (2) at least partly, preferably completely.

Dependent claims

A suspension system for a driving seat, comprising

a frame of the driving seat,
a seat surface of the driving seat,
wherein the frame and the seat surface are movable relative to one another in a height direction (Z),
a scissor-type kinematics system, designed to connect the frame and the seat surface such that they are movable relative to one another at least in the height direction (Z),
a spring device to support a static load of the seat surface, and
an actuating element which is designed to introduce a force flow bidirectionally between the frame and the seat surface to actively damp relative movement of the frame and the seat surface in relation to one another,
wherein the actuating element has a ball bearing, which is arranged within the force flow between the frame and the seat surface in such a way that an axial load can be at least partially kept away from a driving axis of the actuating element.
