In order to promote bloodstream and reduce fatigue, a device of the present invention makes a slight sitting posture change by adding a minute body motion with no necessity of moving a cushion frame or a seat frame though it realizes a supporting pressure change at a wide area, not locally, in a seat cushion or a seat back. It includes a cushioning member (30) for a seat cushion stretched across the cushion frame (10), and a cushioning member (40) for a seat back stretched across the back frame (20). The seat structure of the present invention includes: a lower cloth spring (31a) of a seat cushion or a cloth spring (41) of a seat back stretched across the cushion frame (10) or the back frame (20) via a torsion bar (11); and a cloth spring adjusting member (50) to change a supporting pressure by the cushioning member (30) for the seat cushion and the cushioning member (40) for the seat back through adjusting tension of the lower cloth spring (31a) or the cloth spring (41).

A vehicle seat suspension comprises a scissors assembly connecting lower and upper housings and permitting vertical movement of the upper housing; reciprocating means; an elongated guide member; and guide engaging rollers. Laterally extending front and rear cross members engage upper ends of the scissor links. The reciprocating means allows the upper housing to move fore and aft, and includes horizontally disposed rollers supported by the scissors assembly and received within side tracks forming part of the upper housing. The guide member is mounted to the upper housing and oriented parallel to the fore and aft travel path. Two vertically disposed guide engaging rollers are mounted to the scissors assembly cross members. The guide engaging rollers cooperate with the guide member at spaced locations to stabilize the upper housing in a direction generally perpendicular to its fore and aft travel path.

Es wird ein System (10) zur Messung und Aufzeichnung von Bewegungen in einem Arbeitsfahrzeug (48), insbesondere Vibrationen, vorgeschlagen. Das System (10) umfasst ein Gerät (12) mit einem Gehäuse (14), einen Prozessor zur Verarbeitung von Daten, einen Speicher zur Speicherung von Daten, wenigstens eine Ausgabeeinrichtung zur Ausgabe von Daten, wenigstens eine Eingabeeinrichtung zur Eingabe von Daten und einen Sensor (16) zur Generierung von Bewegungssignalen, wobei die von dem Sensor (16) generierten Signale zur Messung und Aufzeichnung von Bewegungen in Form elektronischer und von dem Prozessor verarbeitbarer Bewegungsdaten herangezogen werden. Um verschiedene Nachteile von im Stand der Technik bekannten Systemen zu überwinden wird vorgeschlagen, den Sensor (16) an oder in dem Gehäuse (14) anzuordnen.

The invention relates to a bellow (10) for an automobile seat frame which has alternating folding peaks (16, 28, 20) and folding troughs (22). In order to prevent an unwanted sagging of the bellow (10), at least one middle folding peak (18) is constructed which varies with one flattening (24) on the front side.

The invention relates to a damping device (20) for a seat (30), especially a vehicle seat, comprising a first deformable hollow body (16), said hollow body being filled with a spring-elastic filling (2), and having a second hollow body (4) which is connected to the first hollow body (16). Both hollow bodies (16, 4) are filled with a fluid under a determined pressure. According to the invention, both hollow bodies (16, 4) are interconnected via at least one valve (6) which opens when a determined excess pressure is reached in the first hollow body (16) with regard to the second hollow body (4), and the valve closes when this excess pressure is fallen short of. Both hollow bodies (16, 4) are additionally interconnected via at least one back flow orifice (3). Under applied force, the volume of the first hollow body (16) is decreased so that the valve (6) opens. The adjusting rise in pressure counteracts the applied force. Once the applied force is removed, the valve (6) closes and the pressure equalization occurs only via the back flow orifice (3) so that the first hollow body (16) only expands slowly. This makes it possible to reliably avoid undesired swinging movements, especially during shock-like applied forces.
