There are improved a vibration absorption characteristic and an impact absorption characteristic. In a suspension mechanism 1 of the present invention, first and second dampers (150, 160) are suspended in parallel between an upper frame (120) and a lower frame (110) with mounting angles different from each other. For this reason, the smaller mounting angle the damper has, the smaller a vertical component of damping force becomes, and the damping force which acts on the upper frame (120) and the lower frame (110) which move up and down relatively is moderate in effectiveness as compared with a case of disposing all the dampers at the same mounting angle. Thus, a sense of incongruity in which strong damping force acts abruptly is suppressed and the vibration absorption characteristic and the impact absorption characteristic are improved, which leads to improvement in ride comfort.

A device for level regulation and level stabilization of a vehicle seat upper part. The device includes an air spring that spring loads a movement of the vehicle seat lower part and of the vehicle seat upper part relative to one another, the vehicle seat lower part and the vehicle seat upper part are arranged in a non-deflected state at a predeterminable distance from one another. The air spring is fluidically connected to a working volume of an additional volume module. A control unit decreases the volume of the working volume in the event of an increase in the distance and increases the volume of the working volume in the event of a decrease in the distance such that the pressure in the air spring can be changed such that the distance between the vehicle seat upper part and a reference surface is substantially unchanged.

A kinetic seat assembly that rotates based on a force applied on an occupant seated therein is provided. The kinetic seat assembly includes a primary seat cushion frame, a primary seat back frame, a secondary seat cushion frame pivotally connected to the primary seat cushion frame, and a secondary seat back frame pivotally connected to the primary seat back frame. The kinetic seat assembly further includes a front pivot mechanism for damping movement between the primary seat cushion frame and the secondary seat cushion frame in a kinetic seat vertical direction, and an upper pivot mechanism for damping movement between the primary seat back frame and the secondary seat back frame in a kinetic seat longitudinal direction.

A kinetic seat cushion assembly that rotates based on a force applied on an occupant seated therein is provided. The kinetic seat cushion assembly includes a primary seat cushion frame, a secondary seat cushion frame, a seat cushion tilt mechanism coupling the secondary seat cushion frame to the primary seat cushion frame such that the secondary seat cushion frame is movable with respect to the primary seat cushion frame, and a front pivot mechanism that pivotally couples a front portion of the primary seat cushion frame to a front portion of the secondary seat cushion frame.
