A space-saving suspension apparatus comprising a coarse suspension device, a mechanical assembly, and a fine suspension device coupling a supported frame to a base frame at a neutral height such that forces and/or displacements of either the base frame or the supported frame result in oppositely directed forces and/or displacements of the other of the base frame and the supported frame. In some embodiments, the neutral height is adjustable.

The invention relates to a vehicle seat comprising a vehicle seat upper part and a vehicle seat lower part, which are spaced apart from one another along a height axis and are connected to one another by means of a scissor frame arrangement, wherein the scissor frame arrangement comprises at least one inner swinging arm and at least one outer swinging arm, wherein the at least one inner swinging arm and the at least one outer swinging arm are mechanically coupled, whereby an angle of inclination of the vehicle seat upper part relative to the vehicle seat lower part can be specified, wherein the mechanical coupling comprises an arm element and a first connecting element pivotably connected thereto, wherein the angle of inclination can be specified by a length of the first connecting element.

A vehicle seat is provided with an upper part which is height-adjustably mounted with respect to a lower part by at least one scissor frame, where the scissor frame has a first scissor arm member and a second scissor arm member which are pivotally mounted about a common axis, where the first scissor arm member has a first, a second and a third lever member which are series-connected, where the first lever member is pivotally mounted with respect to the upper part about a third axis, where the third lever member is pivotally mounted with respect to the lower part about a fourth axis, and where the second lever member is pivotally mounted about the common axis and is rotationally connected to the first lever member by a fifth axis and rotationally connected to the third lever member by a sixth axis.

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 vehicle seat including a seat assembly and an insert assembly. The seat assembly having a seat base portion, a backrest portion. The insert assembly includes upper inserts, lower inserts, and a lumbar cushion. The upper inserts are filled with a combination of a silicone anti-freezing solution and small extruded polystyrene packing balls. The lower inserts are filled with jelly. The upper and lower inserts are mounted within the seat base portion and backrest portion. The lumbar cushion is mounted inside the backrest portion. The conjunction of the lower insert, upper insert and lumbar cushion are configured to bring maximum comfort to a user. The upper inserts, lower inserts and lumbar cushion are configured to bring a user an exceptional stability and support without pressure applied to a tailbone.

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.

The invention relates to a vehicle seat having an upper seat part for receiving a person, which upper seat part comprises a seat plate part and a seat cushion part, the seat cushion part being arranged above the seat plate part in relation to a height axis of the vehicle seat and the seat plate part and the seat cushion part being arranged so as to at least partially overlap in relation to the height axis, forming an intermediate first overlap region, a fluid chamber unit having at least two fluid chambers being arranged at least partially within the first overlap region between the seat plate part and the seat cushion part, a control unit being provided, designed to introduce and to remove a fluid into/from the at least two fluid chambers so that an expansion in the height axis of the at least two fluid chambers can be controlled.
