An assembly for absorbing energy in an overload event has an energy absorber for reducing the load on an object being transported on a loading unit. The energy absorber, in the case of a one-off overload event with an energy input that is sufficiently high that damage to the object would be possible or highly likely in the absence of the energy absorber, to absorb energy in order to reduce the load on the object. Measured values relating to the current state of the loading unit are periodically acquired by a sensor device. A control device identifies an overload event from the acquired measured values. A weight of the object to be transported and a limit value for a load on the object are determined. Following identification of the overload event, damping by the energy absorber is controlled to keep the load on the object below the limit value.

A transit bench seat has a seat with a seat frame. The seat frame is connected to a folding frame that folds between an upright stowed position and a horizontal deployed position. A seat frame cover covers the left or right end of the seat frame. A plurality of rib sections are formed as frame ribs and can be segmented between a vertical fixed portion and a horizontal folding portion. The frame ribs include a first frame rib, a second frame rib, and third frame rib. The frame ribs are formed with a seat nose. The seat nose is supported at a seat nose frame bracket for stability of the frame rib and seat nose. A rear cross bar is placed below a top crossbar. The rear crossbar and the top crossbar are connected to the frame ribs.

An anti-submarine arrangement for a vehicle seat includes an elongated member pivotably attached between opposing members of a seat bottom support structure. A leg is fixedly attached to the elongated member and pivotably attached to a structural portion of the vehicle seat. The elongated member is rotatable forward and downward relative to the structural portion of the vehicle seat. A damper arrangement is attached to the leg and to the structural portion of the vehicle seat. The damper arrangement opposes a forward and downward rotation of the elongated member.

An air suspension apparatus for vehicle seats includes an air shutter connected to a supply port of a control valve configured to supply air so as to adjust the opening degree of an inner air channel through which air supplied to the control valve passes.

A vibration damping device for reducing transmissibility of an excitation frequency comprising: a top plate; a bottom plate secured to a base; a linkage arm arrangement coupled to the top plate and the bottom plate; at least one resilient member coupled to the top plate and the bottom plate; a load sensor for determining a mass of a load on the top plate; at least one accelerometer; a damper coupled to the linkage arm arrangement and the top plate, wherein the damper is controllable to modify stiffness of the device.

A kinetic seat assembly that rotates based on a force applied on an occupant seated therein is provided. The kinetic seat assembly includes a primary seat cushion frame, a primary seat back frame, a secondary seat cushion frame pivotally connected to the primary seat cushion frame, and a secondary seat back frame pivotally connected to the primary seat back frame. The kinetic seat assembly further includes a front pivot mechanism for damping movement between the primary seat cushion frame and the secondary seat cushion frame in a kinetic seat vertical direction, and an upper pivot mechanism for damping movement between the primary seat back frame and the secondary seat back frame in a kinetic seat longitudinal direction.

The invention relates to an apparatus for adjusting a seat position for a vehicle seat, which comprises at least one support element for a seat part and can be connected to a seat substructure, wherein the apparatus comprises at least one first limb and at least one second limb, wherein the limbs can be rotatably arranged on the seat substructure and the at least one support element, wherein a first angle α between the first limb and the support element can be adjusted by an angle adjustment device, wherein the at least one first limb and the at least one second limb each have a lever portion, and these are mechanically coupled, and wherein a change in the angle α causes a displacement of the at least one support element along a height axis Z, and a change in an angle of inclination θ of the support element.

An active system and a computer-implemented method for reducing vibrations of seats in a vehicle is described. The system and method adjust a damping and/or a stiffness of a vibration damper based on system input signals from the vehicle or seat system. The signals include one or more of a signal associated with a user weight, a signal associated with time-dependent movement of a vehicle frame, and a signal associated with time-dependent movement of a seat back or a seat pan. The damping or the stiffness are adjusted by a closed loop control.

A seat suspension including a base frame having a back portion and a bottom portion fixedly securable to a support surface. A carriage assembly is movably connected to the base frame. The carriage assembly includes a transverse member slidably connected to the base frame and a vertical guide member extending upwardly from the transverse guide member and movably connected to the base frame. The carriage assembly includes a suspension support having a first end pivotally secured to the transverse member. A shock compensating mechanism including an adjustment member is slidably disposed on a pivot surface secured to the transverse guide member. Movement of the adjustment member changes shock compensation properties of the shock compensating mechanism. A height adjustment mechanism disposed on the frame includes an actuator wherein operation of the actuator selectively moves the seat frame, the carriage assembly, and the shock compensating mechanism relative to the base frame.
