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 Z and are connected to one another by means of a scissor frame arrangement, wherein at least two damping elements are provided between the vehicle seat upper part and the vehicle seat lower part, the at least two damping elements each extending, inclined at an angle of attack α, relative to a first axis parallel to the height axis.

A vehicle seat includes a seat cushion and a seat back. The seat cushion includes a storage member configured to store fine particles, shaped into a bag, and made of a flexible and gas-impermeable material, and a gas supply/suction member. The gas supply/suction member fluidizes the fine particles stored in the storage member by supplying the gas to the storage member to make it easy to change a shape of the storage member. The gas supply/suction member solidifies the fine particles stored in the storage member by sucking the gas from the storage member to make it hard to change the shape of the storage member. The storage member includes a rigid inclined member disposed on at least one end of a periphery of the storage member and configured to be inclined downward from an outer periphery of the seat cushion toward a center of the seat cushion.

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.

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.

A pneumatic seat support by itself supports a seat above a floor of a vehicle. The pneumatic seat support has upper and lower air chambers. The lower air chamber is a rigid cylindrical tube. The upper air chamber is a flexible cylindrical bellows, with a diameter greater than the diameter of the tube. Three or more linear shafts extending through the upper air chamber and into the lower air chamber provide a single-degree-of-freedom bearing support structure that allows vertical motion of the seat but withstands horizontal loads on the seat. When the seat moves vertically downward, it compresses air in both chambers, providing a seat support system with a natural oscillation frequency which is less than 2.4 Hz, and preferably in the range of 1.5-2.2 Hz.

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.

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.

Various embodiments of the present technology may comprise a method and apparatus for a space-saving suspension system. In various embodiments, the apparatus may comprise a fine suspension device, a coarse suspension device, and a mechanical assembly. In various embodiments, the fine suspension device is arranged at an angle greater than zero degrees from the z-axis. In various embodiments, the mechanical assembly is coupled to the fine suspension device and a payload, such that when a force is exerted on the mechanical assembly by the payload, an applied force is transmitted to the fine suspension device.

A vehicle seat includes a seat cushion and a seat back. The seat cushion includes a storage member configured to store fine particles, shaped into a bag, and made of a flexible and gas-impermeable material, and a gas supply/suction member. The gas supply/suction member fluidizes the fine particles stored in the storage member by supplying the gas to the storage member to make it easy to change a shape of the storage member. The gas supply/suction member solidifies the fine particles stored in the storage member by sucking the gas from the storage member to make it hard to change the shape of the storage member. The storage member includes a rigid inclined member disposed on at least one end of a periphery of the storage member and configured to be inclined downward from an outer periphery of the seat cushion toward a center of the seat cushion.

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.
