20090026816 | VEHICLE SEAT WITH BASE FRAME AND ADJUSTABLE SEAT FRAME - The invention relates to a vehicle seat comprising a base frame and comprising a seat frame which can be adjusted relative to the base frame, and comprising a gas spring which acts between this base frame and this seat frame and which is supported against the seat frame, wherein at least one pressure source and at least one valve device which is in fluid connection with this pressure source are provided, and in that furthermore a manually operated actuation element is provided for adjusting the vehicle seat, wherein this at least one valve device is arranged on or in the actuation element. | 01-29-2009 |
20090008977 | Vehicle seat with slide valve - The invention relates to a vehicle seat with a height-adjustable seat frame which comprises at least two seat frame parts which can move relative to one another and at least one fluid spring, in particular an air spring, arranged on the seat frame parts for height adjustment purposes, with at least one control device which is provided for influencing the fluid spring and which comprises at least one valve device with control valves which is attached to the first seat frame part and is designed to control fluid flows for the fluid spring, and also a control element which is provided on a second seat frame part and is designed to actuate the control valves, so that a height adjustment and/or damping oscillatory movement of the vehicle seat is ensured, wherein the valve device comprises an internally cylindrical component with at least one rod element arranged displaceably therein as a control element, wherein at least one fluid intake and discharge opening of the rod element can selectively be assigned to one of the control elements by a relative displacement of the cylindrical component and the rod element with respect to one another. | 01-08-2009 |
20080262785 | METHOD AND DEVICE FOR ANALYSING THE EFFECTS OF THE VIBRATIONS OF A VEHICLE ACTING ON A PERSON - Methods and systems for analyzing vibrations of a vehicle acting on a person. The person uses a sprung vehicle seat. A detection unit detects acceleration values fitted to the vehicle seat in the x-, y- and z-axes at preset intervals of time. An increase over time of the acceleration values cumulated with one another is determined and a time calculated from this when a pre-determinable permitted maximum of the cumulated acceleration values will foreseeably be reached. | 10-23-2008 |
20080258522 | METHOD AND DEVICE FOR ANALYSING THE EFFECTS OF THE VIBRATIONS OF A VEHICLE TRANSMITTED TO A PERSON - Device and method for recording vibrations transmitted from a vehicle to a person. The person is using a cushioned and preferably sprung vehicle seat of a vehicle by way of at least one detector unit for detecting vibration values, whereby the detector unit is arranged on the vehicle seat frame or an associated component and an analysis unit for analysing the vibration values detected calculates vibration results for the vibration acting on the person using a preset transmission function. | 10-23-2008 |
