Abstract: The invention relates to a compressor system, in particular a screw compressor, for compressing gases, preferably air, comprising a compressor block (11) in which a compressor chamber (12) is formed in which the gas is compressed via mechanical compression means (13), wherein the compressor chamber (12) has an inlet opening (14) on the inflow side and an outlet opening (15) on the outflow side, and a control device (16) for controlling a drive (17) of the compression means (13), wherein the control device (16) is operatively connected to a temperature sensor (19) and/or a humidity sensor (20) in order to determine state conditions of the gas entering at the inlet opening (14), characterized in that the temperature sensor (19) and/or the humidity sensor (20) are arranged at or in the control device (16) within the compressor system for detecting a temperature Tc prevailing there or a humidity Fc prevailing there, and the control device (16) comprises a processing device (23) in order to draw conclusions from t

Abstract: A backrest for a vehicle seat, comprising a backrest frame on which a backrest head support element provided for supporting a seat user in the shoulder region can be pivoted. In particular, the support element can be pivoted via a drive unit arranged on the support element and a lever mechanism which interacts with the drive unit so as to be actuated by an external force.

Abstract: A liquid absorber is for absorbing and damping vibrations in structures, in particular in slender, vertically oriented structures. It is therefore an object to overcome the disadvantages of the prior art and to provide a liquid absorber which lessens the sloshing effect of a fluid in the liquid absorber. A further object is to provide a liquid absorber which achieves an increase in the damping ratio for containers with sloshing lengths of more than 80 cm. A further object is to enable fine adjustments to be made with regard to the damping ratio and to develop a vibration absorber which has optimal damping properties (“Den Hartog”) and considerably improves the response behavior over a broad frequency spectrum.

Abstract: It is provided a lever for a vehicle seat, comprising two bearing portions for pivotally connecting the lever to a further component in each case; a carrier element via which forces can be transmitted between the bearing portions; a displacement element on which one of the bearing portions is provided; and an elongate guide portion which is blocked in an initial position by a deformation portion so that the displacement element is fixed relative to the carrier element, wherein the deformation portion can be deformed by the action of forces acting between the bearing portions such that the guide portion is released and the displacement element is displaceable relative to the carrier element.

Abstract: It is provided a structural assembly for a vehicle seat backrest, with a surface element which is configured and designed to form at least one part of a rear wall of the vehicle seat backrest and/or to close a recess for a load through-opening in the vehicle seat backrest, and at least one interface element which is configured and designed for connecting to a further component of the vehicle seat backrest. The surface element is produced from a thermoformable composite material and is connected by a material connection to at least one part of the interface element. The at least one interface element is configured as a duct.
