A seat suspension including a base frame having a back portion and a bottom portion fixedly securable to a support surface. A carriage assembly is movably connected to the base frame. The carriage assembly includes a transverse member slidably connected to the base frame and a vertical guide member extending upwardly from the transverse guide member and movably connected to the base frame. The carriage assembly includes a suspension support having a first end pivotally secured to the transverse member. A shock compensating mechanism including an adjustment member is slidably disposed on a pivot surface secured to the transverse guide member. Movement of the adjustment member changes shock compensation properties of the shock compensating mechanism. A height adjustment mechanism disposed on the frame includes an actuator wherein operation of the actuator selectively moves the seat frame, the carriage assembly, and the shock compensating mechanism relative to the base frame.

A sealed boat seat suspension including a plurality of sealed rails. The sealed boat seat suspension also includes a boat seat attachment component which is coupled to the plurality of sealed rails. The sealed boat seat suspension also includes a boat seat attachment component which is movable with respect to at least a portion of the plurality of sealed rails. The sealed boat seat suspension also includes a suspension component which is coupled to the boat seat attachment component such that the suspension component provides at least some control of movement of the boat seat attachment component with respect to at least a portion of the plurality of sealed rails.

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.

The invention relates to a device for adjusting a seat position for a vehicle seat, wherein the device comprises at least one support element for a seat part and can be connected to a seat substructure, wherein the device comprises at least one first leg and at least one second leg, the legs being rotatably arranged on the seat substructure and the at least one support element, wherein a first angle α can be adjusted between the first leg and the support element by means of an angle adjustment device, wherein the at least one first leg and the at least one second leg are mechanically coupled, wherein a change of the angle α causes a displacement of the at least one support element along a height axis Z and along a longitudinal axis X.

The present disclosure provides a damper system for a suspension of a vehicle seat. A linkage of the damper system can be configured to cause a damper to provide different damping characteristics when the suspension moves towards a neutral position than when the suspension moves away from the neutral position.

The invention relates to a vehicle seat comprising a vehicle seat upper part and a vehicle seat lower part, which are spaced apart from one another along a height axis Z and are connected to one another by means of a scissor frame arrangement, wherein at least two damping elements are provided between the vehicle seat upper part and the vehicle seat lower part, the at least two damping elements each extending, inclined at an angle of attack α, relative to a first axis parallel to the height axis.

A vehicle seat having a lower part and an upper part displaceable relative to the lower part in a longitudinal direction, and a spring element for cushioning longitudinal horizontal movements of the upper part relative to the lower part. A scissors frame connects the lower part and the upper part so that they can move relative to one another. The spring element comprises a first holding arm connected to the upper part, and a second holding arm connected to the scissors frame. The first holding arm and the second holding arm are connected to one another by a first connecting element such that the first holding arm is displaced towards the second holding arm during a displacement of the upper part relative to the lower part. A resiliently deformable spring element part is deformed during a displacement of the first holding arm relative to the second holding arm.
