A passenger seat for an aircraft, including a bottom support configured to be connected to a floor of the aircraft, a seat pan frame, and a support structure interconnecting the seat pan frame to the bottom support, the support structure including a front support member pivotally connected to a front end of the seat pan frame, the front support member including a respective strut on each side of the seat pan frame, each respective strut having a bottom end rigidly connected to the bottom support and an opposed top end located under the seat pan frame, the bottom end being inwardly, downwardly and rearwardly offset with respect to the top end.

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.

An assembly for a hybrid motor vehicle, in particular a partially electrified hybrid motor vehicle, having a vehicle battery and a vehicle seat comprising a seat surface. The vehicle seat is connected or connectable to a vehicle floor of the hybrid motor vehicle by means of a substructure having at least two seat rails. The vehicle battery is arranged or arrangeable beneath the vehicle seat and above the vehicle floor. The vehicle battery is held on the vehicle seat by means of a suspension means attached to the top side, or in an upper region, of the vehicle battery.

The invention relates to a device for adjusting a seat position for a vehicle seat, wherein the device comprises at least one support element for a seat part and can be connected to a seat substructure, wherein the device comprises at least one first leg and at least one second leg, the legs being rotatably arranged on the seat substructure and the at least one support element, wherein a first angle α can be adjusted between the first leg and the support element by means of an angle adjustment device, wherein the at least one first leg and the at least one second leg are mechanically coupled, wherein a change of the angle α causes a displacement of the at least one support element along a height axis Z and along a longitudinal axis X.

An active suspension system for a sprung mass that is supported and movable relative to an unsprung mass. The active suspension system has a suspension that comprises an electromagnetic actuator that is adapted to produce an arbitrary force on the sprung mass that is independent of the position, velocity and acceleration of the sprung mass, a control system that provides control signals that cause the suspension to exert force on the sprung mass, to control the position of the sprung mass relative to the unsprung mass, wherein the control system implements a control algorithm with one or more constants, and a user interface that is operable to cause a change of one or more of the control algorithm constants so as to vary how closely motion of the sprung mass follows motion of the unsprung mass.

The invention relates to a suspension system (1), preferably a driver seat (1), comprising a first suspension part (10), preferably a frame (10) of the driver seat (1); a second suspension part (11), preferably a seat surface (11) of the driver seat (1), wherein the two suspension parts (10, 11) are movable relative to each other in at least one first spatial direction (Z), preferably in the vertical direction (Z); a kinematic system (12), preferably a scissor kinematic system (12) which is designed to connect the two suspension parts (10, 11) in a movable manner relative to each other at least in the first spatial direction (Z); a suspension device (13) which is designed to support the static load of the second suspension part (11); and an actuator (2) which is designed to introduce a force bidirectionally between the two suspension parts (10, 11) and thereby actively damp the relative movement between the two suspension parts (10, 11). The suspension system (1) is characterized in that the actuator (2) has a bearing (28), preferably a ball bearing (28), which is arranged within the power flow between the two suspension parts (10, 11) such that an axial load can be kept away from the driven axle of the actuator (2) at least partly, preferably completely.

An adjustable suspended seat apparatus having a tuned frequency-tailored damping through stratified seat structure is described. The damping seat structure includes: a first material of a plurality of materials having a first characteristic to provide a first damping effect in a first layer. A second material of the plurality of materials based on a second characteristic to provide a second damping effect in a second layer, the first material or the second material having an adjustable damping characteristic. The suspended seat apparatus includes a seat base configured to have the seat coupled thereto; a suspension system coupled to the seat base, the suspension system comprising: an adjustment feature configured to adjust operation of the suspension system; and a chassis mount coupled to the suspension system, the chassis mount configured to be coupled to a vehicle.

A cushion suspension for a vehicle seat may have a support structure with a substantially tub-shaped profile and at least two lateral portions. Each of the lateral portions may have a flexible suspension portion. A seating surface assembly for a vehicle seat is also disclosed.

A vehicle seat includes: left and right side frames disposed left and right separately from each other; a first support member disposed between the left and right side frames to support an occupant; and left and right second support members joined to left and right sides of the first support member and having left and right outer sides supported by the side frames to support the occupant in conjunction with the first support member. The first support member is a plate-shaped member, and has left and right ischial region through holes formed in positions corresponding to ischial bones of the occupant. The second support members are located at least partially within front and rear limits defined by an expanse of the ischial region through holes.
