Disclosed is a vehicle seat (1) comprising a seat cushion (2) and a seat back (4), wherein the seat cushion and the seat back are comprised of: a frame structure (8) to be fixed to the vehicle body; and a seating member (10) supported by the frame structure having an elastic deformation property and a vibration damping property and allow an occupant to be seated therein, and wherein the vehicle seat satisfies the following relationship: D.sub.S/D.sub.F≥20, where D.sub.S denotes a deformation amount of the seating member itself in a situation where a load W is applied at a position X.sub.S of the seating member, and D.sub.F denotes a displacement of a position X.sub.F of the frame structure corresponding to the position X.sub.S, in a situation where the frame structure is fixed to the vehicle body, and the given load W is applied at the position X.sub.F.

A disturbance cancellation and generation seat system includes a seat mounted to a structure of a vehicle. The seat is accelerated due to a disturbance acceleration received in the structure and transferred to the seat. A seat control unit generates a force cancellation command signal. An actuation device is connected to the structure and is in communication with the seat control unit. The actuation device in response to receipt of the force cancellation command signal induces a cancellation acceleration motion into the seat which is equal but opposite to and therefore cancels an acceleration motion of the seat induced by the disturbance acceleration.

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 pneumatic seat support by itself supports a seat above a floor of a vehicle. The pneumatic seat support has upper and lower air chambers. The lower air chamber is a rigid cylindrical tube. The upper air chamber is a flexible cylindrical bellows, with a diameter greater than the diameter of the tube. Three or more linear shafts extending through the upper air chamber and into the lower air chamber provide a single-degree-of-freedom bearing support structure that allows vertical motion of the seat but withstands horizontal loads on the seat. When the seat moves vertically downward, it compresses air in both chambers, providing a seat support system with a natural oscillation frequency which is less than 2.4 Hz, and preferably in the range of 1.5-2.2 Hz.

A vehicle seat having a vehicle seat underbody, comprising: a base plate; a side horizontal suspension; a rolling suspension comprising a rod element rotatably mounted with respect to the side horizontal suspension; a scissors-type frame having a first swing and a second swing, wherein the first swing is connected by a first slide element to the rod element and the second swing is connected by a second slide element to the rod element and the first swing is connected to the first slide element and the second swing is connected to the second slide element; a first element carrier; a lengthwise horizontal suspension; and a first spring element, which is connected on the one hand to the first element carrier and on the other hand to the base plate or one of the swings.

A position control system is disclosed that replaces a parallelogram or quadrilateral movement system with greater efficiency, economy, stability and utility by eliminating one of the four links and providing a non-linear path to be followed. This system includes a dynamic triangular mechanism for movement from a first position to at least a second position, with at least three (3) link members interconnected by pivots with a first base link member defining a non-linear path, said first base link member having a fixed base pivot and a follower pivot that moves along the non-linear path, a second fixed length support link member pivotally connected to the fixed base pivot, and a third follower link member pivotally connected to, and located between, the follower pivot and a connector pivot, wherein the follower link member is adapted for following the non-linear path, thereby creating a virtual triangle defined by the three link members while the follower pivot, fixed base pivot and the connector pivot interconnect the first base link member, the second fixed length support link member and the third follower link member.

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.

A sofa base system includes a plurality of channel assemblies and a motor. The channel assemblies are disposed on a frame portion adapted for operational engagement with an associated vehicle, and each channel assembly includes a sliding bracket and an outer bracket arranged on the sliding bracket, as well as a guide rod. The sliding bracket and outer bracket are arranged to slide on the guide rods via a plurality of roller members. The sliding bracket and an outer bracket are coupled to a shuttle member that is drive by a drive rod, and the drive rod is operatively connected to the motor via drive shafts and gearboxes.
