A seat suspension includes a base including a base hook and a seat platform provided with a seat. A first link couples a first rotational axis of the base and a third rotational axis of the seat platform and is configured to be rotatable about the first rotational axis and the third rotational axis. A second link couples a second rotational axis of the base and a fourth rotational axis of the seat platform and is configured to be rotatable about the second rotational axis and the fourth rotational axis. A link hook is provided on the second link. An elastic member is latched to the base hook and the link hook and is configured to pull the link hook toward the base hook. A first angle between a contracting direction of the elastic member and a rotation direction of the link hook increases as the elastic member expands.

An air suspension apparatus for vehicle seats includes an air shutter connected to a supply port of a control valve configured to supply air so as to adjust the opening degree of an inner air channel through which air supplied to the control valve passes.

Vehicle seat having a pitching spring unit, a vehicle seat upper part and a vehicle seat lower part of the vehicle seat being connected such that they can be moved relative to one another by means of a scissor frame arrangement, comprising a first scissor arm and a second scissor arm which cross in a first region as viewed in a vehicle seat width direction, the pitching spring unit comprising a spring element carrier and a spring element, the spring element being connected on one side to the vehicle seat upper part, the vehicle seat lower part or the scissor arms and on the other side to the spring element carrier which is connected to the first scissor arm such that it can be rotated about a second rotational axis and to the second scissor arm such that it can be rotated about a third rotational axis.

A seat for a vehicle including support links enabling a rotating motion and a sliding motion between a seat frame and seat rails, the support links being mounted so that the seat may be rotated in the forward and rearward directions as in a seesaw motion about a shaft of a vehicle in a width direction of the vehicle, so as to easily implement a facing mode posture, in which passengers sit facing each other, a relaxed comfort posture, etc.

A seat for a vehicle includes a seat cushion and an adjustment and suspension device having a base fixed to the frame and a supporting plate fixed to the seat cushion movable in translation relative to the base in a direction of elevation. The seat also has a restraint system that includes: at least one restraint member fixed to the frame, the restraint member defining at least one through opening extending along a main direction of elongation substantially parallel to the direction of elevation; and at least one restraint element fixed to the supporting plate, the through opening of the restraint member receiving the restraint element free in translation along the main direction of elongation.

A suspension component (730), including: an elastomeric component top member (832); an elastomeric component bottom member (830); and a plurality of elastomeric zig-zag columnar elements (800). The elastomeric zig-zag columnar elements connect the elastomeric component top member to the elastomeric component bottom member and are separated from each other by a gap (806).

A seat adjusting structure includes a seat body. A damping force unit is installed at an upper end of the seat body, and a cab connecting plate is installed at a lower end of the seat body. An electronic controller and a seat weight sensor are installed between the damping force unit and the cab connecting plate. A rigidity unit and an operator presence indicator are installed at a lower part of the damping force unit, and a seat damper is installed above the cab connecting plate. The operator presence indicator detects whether an operator exists, while the seat weight sensor detects whether the weight of the operator is within a set range. The electronic controller receives detection signals from the operator presence indicator and the seat weight sensor and controls the damping force unit and the rigidity unit to adjust the rigidity and damping force of the seat damper.

A space-saving suspension apparatus comprising a coarse suspension device, a mechanical assembly, and a fine suspension device coupling a supported frame to a base frame at a neutral height such that forces and/or displacements of either the base frame or the supported frame result in oppositely directed forces and/or displacements of the other of the base frame and the supported frame. In some embodiments, the neutral height is adjustable.

A vehicle seat mounting system includes a seat mount plate and a vehicle mount plate. A vertically operable scissor linkage assembly is disposed between the seat mount plate and the vehicle mount plate and is oriented such that respective opposing ends of a first scissor arm and a second scissor arm are each secured to a respective one of the seat mount plate and the vehicle mount plate. A spring assembly is disposed between the seat mount plate and the vehicle mount plate and is oriented to cooperate with the scissor linkage assembly to resist translation between the vehicle mount plate and the seat mount plate. An adjuster assembly cooperates with the spring assembly and is operable to manipulate the proportion of the spring assembly that is available to be engaged to resist motion of the mounting system.

Provided is a semi-active seat suspension system that minimizes vibration and energy transmission from a vibration/energy source, such as a motor vehicle, to a seated occupant by means of a spring and computer-controlled damper suspension system. Using a variety of sensors to determine an ideal damping rate at a given point in time, the system adjusts the damping rate in real time to provide the best possible ride to the occupant given the constraints of the system.
