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.

Suspension systems and grounds maintenance vehicles incorporating the same are disclosed. The suspension system may include biasing elements or springs that may be adjusted to vary the preload and thus change the spring and dampening characteristics of the suspension system. In some embodiments, the system may include an adjustment mechanism that permits simultaneous adjustment of two springs via a single action. In other embodiments, features adapted to assist an operator with mounting/dismounting the vehicle are disclosed.

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.

Examples herein describe a vehicle seating system. The vehicle seating system may include a rail mounted to a vehicle roof and supported by a vehicle frame. The vehicle seating system may include an anchor system movable along the rail, the anchor system including: a locking device that locks the anchor system in a position along the rail; and a heating, vacuuming, and air conditioning (HVAC) port in communication with a HVAC duct within the vehicle roof. The vehicle seating system may include an interchangeable seat module that connects to the anchor system to suspend the seat module above a floor of the vehicle, wherein the seat module connects to the HVAC port.

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 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 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.

The invention relates to a system for representing vibrations for a vehicle, comprising a vehicle seat with an upper part and a lower part, which are mounted movably relative to each other by means of a vibration device, wherein at least a first sensor, which is adapted to detect at least one first characteristic of a first acceleration of the upper part relative to the lower part, is arranged on the upper part, and wherein at least one second sensor, which is adapted to detect at least one second characteristic of a second acceleration of the lower part relative to a subsurface of the vehicle, is arranged on the lower part, wherein a display device is arranged with a first section and a second section, in each case exhibiting a complete division into at least two, preferably three segments, wherein the size ratios of the at least two segments to one another can be updated depending on a current value of the at least one first characteristic or the at least one second characteristic.

A connection bar mounting structure includes: link members, each including a first hole part in a middle part; vehicle members, each configured to rotatably support each link member at a first fixation part of each link member; side frames, each configured to rotatably support each link member at a second fixation part of each link member opposite to the first fixation part across the first hole part; and a connection bar, each end thereof fixed to the first hole part of each link member. Each link member has a first bending rigidity reduced section between the middle part and the first fixation part and a second bending rigidity reduced section between the middle part and the second fixation part, the first and second bending rigidity reduced sections having bending rigidity smaller than those of the middle part, the first fixation part, and the second fixation part.
