An isolator performance data logging system comprising a displacement unit for measuring a displacement of the isolator. the displacement unit comprises a displacement sensor housing fixable relative to a mitigated end of the isolator, a target fixable relative to an unmitigated end of the isolator. A displacement sensor is located within the displacement sensor housing for measuring a displacement of the target relative to the displacement sensor. A first accelerometer unit is fixable relative to the mitigated end of the isolator. A second accelerometer unit is fixable relative to the unmitigated end of the isolator.

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.

Embodiments related to the operation of an active seat suspension using prefiltered road data are described. In one embodiment, the prefiltered road data may be filtered to exclude road and/or driving inputs with low frequencies, or long length scales, such as hills, curves Such an embodiment may at least partially reduce operation of an active seat suspension in response to these low frequency long length scale of inputs where displacements of the vehicle may be greater than a range of motion of the active seat suspension while still permitting the active seat suspension to respond to higher frequency inputs.

Embodiments related to systems and methods for controlling the relative amounts of rotation and heave motions applied to a seat by an active seat suspension system are described.

A modular vehicle seat assembly including: a seat bottom structure module adapted to be rigidly or translatably coupled to one of a seat base module and a structure of a vehicle, securely coupled to a seat bottom cushion carrier module, and rigidly or pivotably coupled to a seat back structure module; a seat back structure module adapted to be rigidly or pivotably coupled to the seat bottom structure module and securely coupled to a seat back cushion carrier module; the seat bottom cushion carrier module adapted to be securely coupled to the seat bottom structure module; and the seat back cushion carrier module adapted to be securely coupled to the seat back structure module. The modular vehicle seat assembly further including a seat base module adapted to be rigidly coupled to the structure of the vehicle and to the seat bottom structure module.

A device for level regulation and level stabilization of a vehicle seat upper part. The device includes an air spring that spring loads a movement of the vehicle seat lower part and of the vehicle seat upper part relative to one another, the vehicle seat lower part and the vehicle seat upper part are arranged in a non-deflected state at a predeterminable distance from one another. The air spring is fluidically connected to a working volume of an additional volume module. A control unit decreases the volume of the working volume in the event of an increase in the distance and increases the volume of the working volume in the event of a decrease in the distance such that the pressure in the air spring can be changed such that the distance between the vehicle seat upper part and a reference surface is substantially unchanged.

A vehicle body structure of a four-wheeled vehicle includes a pair of side members (8) extending in a fore and aft direction along either side of the vehicle body, a plurality of cross members (41, 42, 43) extending laterally between the side members, and a floor panel (58) attached to an upper side of the cross members. One of the cross members (42) passes through an intersection point of diagonal lines of a rectangular formation of supporting points of the four wheels, and at least one of the seat mounts (72) is positioned on the one cross member.

A vehicle seating assembly including a seat cushion and a seat frame assembly with a carrier assembly and a displaceable platform coupled to the carrier assembly and selectively deployable from a design position to a fully deployed position in response to a sudden deceleration of the vehicle.

A vehicle seat includes a seat cushion supported on a frame. The seat cushion is removable from the frame to allow access an area beneath the seat. A handle is formed on a projecting portion of the seat cushion to facilitate grasping the seat cushion and to allow the seat cushion to be removed from the frame. A seat stopper is provided for preventing the projecting portion from contacting directly against a console or other surrounding part of the vehicle.

Various embodiments of the present technology may comprise a method and apparatus for a space-saving suspension system. In various embodiments, the apparatus may comprise a fine suspension device, a coarse suspension device, and a mechanical assembly. In various embodiments, the fine suspension device is arranged at an angle greater than zero degrees from the z-axis. In various embodiments, the mechanical assembly is coupled to the fine suspension device and a payload, such that when a force is exerted on the mechanical assembly by the payload, an applied force is transmitted to the fine suspension device.
