According to the disclosure, a seat pad 2 includes a bag-contained pad part 250 including a foam body 240 and a bag body 230 arranged inside the foam body 240.

A motor vehicle seat having a backrest and a seat part, at least one flexible, fluid-fillable hollow body attached to the seat part or the backrest, and at least two chambers that are in fluid communication with one another. The chambers are arranged one on top of the other and have in their walls corresponding passages which enable a fluid exchange between the chambers. The chambers are firmly connected to one another in the region of the passages, wherein the volume of the lowermost chamber adjacent to the seat part or the backrest is the largest and the volume of each additional chamber is smaller compared with the volume of the chamber below it. The chambers are arranged one on top of the other such that the maximum lift of the fluid-fillable hollow body when it is being filled with fluid is outside the center of the lowermost chamber.

An assembly for a vehicle seat that includes: a support element defining a through opening, a padding element attached at least in part to the support element, and a ventilation system assembled to the support element in fluidic communication with the through opening. An inner surface of the support element and/or an inner surface of the padding element define at least one groove. An inner surface of the groove, the inner surface of the support element, and an inner surface of the padding element define an internal volume there between in fluidic communication with the through opening.

An air cushion arrangement installable in an interior of a seat having a seat surface may have at least one air cushion and an air supply system for variably supplying the at least one air cushion with air, wherein at least one air cushion is assigned a pulsation generator, the at least one air cushion being non-fluidically connected to the pulsation generator. The air cushion and the pulsation generator are configured to generate a pulsation in a direction of the seat surface of the seat (e.g., if the air cushion arrangement were installed in the interior of the seat). A seat assembly including such an air cushion arrangement is also disclosed.

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.

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 kinetic seat assembly includes a primary seat cushion frame, a secondary seat cushion frame movable relative to the primary seat cushion frame, a primary seat back frame, a secondary seat back frame movable relative to the primary seat back frame, a pair of lateral dampers extending between the primary seat back frame and the secondary seat back frame, a pair of vertical dampers extending between the secondary seat back frame and the primary seat cushion frame, a pair of fluid reservoirs for providing a fluid into the pair of lateral dampers and the pair of vertical dampers, and an electronic control unit configured to control the rate at which the fluid is provided to and drawn out of each of the dampers to control a damping effect. In embodiments, an end of the lateral dampers is permitted to move freely relative to the secondary seat back frame.

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.

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.
