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 seat suspension includes a frame fixedly securable to a structure. A suspension assembly is operably connected to the frame. A seat support is adapted to receive a seat, and the seat support is operably connected to the suspension assembly. The suspension assembly includes a first elongate suspension bar slidably disposed on a pivot surface. The first suspension bar has a first end slidingly secured to the seat support and a second opposed end secured to a shock compensating device. The suspension bar is translatable relative to the pivot surface, wherein moving the suspension bar changes the shock compensation of the suspension assembly.

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 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 seat suspension includes a base including a base hook and a seat platform provided with a seat. A first link couples a first rotational axis of the base and a third rotational axis of the seat platform and is configured to be rotatable about the first rotational axis and the third rotational axis. A second link couples a second rotational axis of the base and a fourth rotational axis of the seat platform and is configured to be rotatable about the second rotational axis and the fourth rotational axis. A link hook is provided on the second link. An elastic member is latched to the base hook and the link hook and is configured to pull the link hook toward the base hook. A first angle between a contracting direction of the elastic member and a rotation direction of the link hook increases as the elastic member expands.

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.

A seat suspension includes a frame fixedly securable to a structure. A suspension assembly is operably connected to the frame. A seat support is adapted to receive a seat, and the seat support is operably connected to the suspension assembly. The suspension assembly includes a first elongate suspension bar slidably disposed on a pivot surface. The first suspension bar has a first end slidingly secured to the seat support and a second opposed end secured to a shock compensating device. The suspension bar is translatable relative to the pivot surface, wherein moving the suspension bar changes the shock compensation of the suspension assembly.

A lower guide frame for a vertical suspension system of a vehicle seat having a left-hand slide and, parallel thereto, a right-hand slide which are connected to each other via a lower crosspiece. Attached to an upper side of at least one slide is a reinforcing profile which has a horizontal portion, via which it is connected to the upper side of one slide, and adjoining the horizontal portion is an oblique portion that is oriented obliquely downwards and outward. Adjoining the oblique portion is a vertical portion that, in the assembled state, extends to just above a vehicle floor.

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 lower seating structure comprises an upper support layer, an intermediate resilient layer, a molded bottom seat panel, a seat frame assembly, and a tension member. The molded bottom seat panel extends across a width of the lower seating structure and the tension member is fixedly attached to each of a pair of opposed sides of the molded bottom seat panel and extends across the width of the lower seating structure.
