An occupant support adapted for use in a vehicle includes a seat frame, a seat pad, and a suspension system. The seat frame is adapted to couple with the vehicle for movement with the vehicle. The seat pad is adapted to provide a comfortable support interface. The suspension system provides relative movement between the seat pad and the seat frame.

This invention is a seat with an adjustable back and/or an adjustable base. The adjustable back and/or base can be adjusted in response to rough terrain or water encountered by a vehicle in which the seat is located.

The invention relates to a vehicle seat comprising a backrest portion and a seating surface portion, each of which is arranged to be connected with a seat base portion, wherein the backrest portion is resiliently arranged and supported to be able to swivel with respect to the seat base portion, and wherein the seating surface portion is arranged to be able to move in at least a longitudinal direction of the seat frontwards and rearwards with respect to the seat base portion, wherein the backrest portion and the seating surface portion are operatively connected together via a first lever arrangement in such a way that the seating surface portion is able to move rearwards in the longitudinal direction of the seat when the backrest portion makes a suspending movement with respect to the seat base portion in a direction away from the seating surface portion.

A seating system for a vehicle is disclosed. The seating system includes a support surface having a surface contour formed by first springs having fixed stiffness values, a frame, and second springs having adjustable stiffness values coupling the support surface and the frame. The first springs and the second springs together control motion of the support surface in relation to motion of the frame.

A seat assembly reclines during an under-vehicle explosion or other upward impact on the vehicle to mitigate spinal and lower leg damage to a human occupant. The seat assembly has a back frame portion and a lower frame portion. The lower frame portion has a pivotal connection with an energy absorbing mechanism mounted to the vehicle floor. The pivotal connection includes a stop mechanism to prevent seat assembly tilt during normal vehicle operation but allow tilt due to an explosion. A second mechanism is disposed between the back frame portion and the floor; this mechanism controls the seat assembly pivot and provides further absorbing of energy from the upward impact. Projections from the front of the lower frame portion toward the floor can be used to enhance seat assembly pivoting; specially designed seat engagement levers can be used for this purpose as well.

A kinetic seat assembly including a primary seat cushion frame including a rear rod extending between opposite rails, a secondary seat back frame movable relative to the primary seat cushion frame, a pair of clamps provided on the rear rod of the primary seat cushion frame, and a pair of vertical dampers coupled between the secondary seat back frame and the pair of clamps on the primary seat cushion frame, each clamp receiving an end of a corresponding vertical damper. In embodiments, the vertical dampers are arranged in a V-shape such that the vertical dampers are oriented at an angle relative to one another such that a distance between a first end of each vertical damper is greater than a distance between a second end of each vertical damper.

A gyro seat includes: a seat body comprising a seat cushion and a seat back coupled to the seat cushion; and a seat gyroscope mounted to the seat body, the seat gyroscope compensating a movement of the seat body by control of first, second and third axes, where the first axis corresponds to a yaw of the seat body as a z axis of an xyz coordinate system, the second axis corresponds to a pitch of the seat body as an x axis of the xyz coordinate system, and the third axis corresponds to a roll of the seat body as a y axis of the xyz coordinate system.
