Abstract: The invention relates to a device and a method for separating particles of different sizes in a liquid. The invention additionally relates to applications of the device according to the invention. The device according to the invention and the method according to the invention involve the capability of modifying the diameter of the pores of the at least one filter element of the device in a controlled manner (e.g., the pore diameter can be increased or decreased). The device and method have the advantage that particles of different sizes (e.g., biological cells and/or endosomes) of a liquid can be separated from one another with a high degree of separation efficiency, and the particles are separated in a simple, quick, and inexpensive manner. High yields can be produced, and the separated particles can be provided in a therapeutically applicable liquid (e.g., blood plasma).

Abstract: It is provided an adjusting device for a seat element of a vehicle seat supporting a body part of a seat user, with at least one driving device comprising a spindle drive and at least one adjustable support element for changing the contour or position of the seat element, wherein the spindle drive comprises a spindle extending along a spindle axis, which is floatingly mounted at a spindle end via a spindle holder such that at this spindle end the spindle is displaceable along at least one spatial direction extending transversely to the spindle axis. The spindle holder comprises a first and a second compensating element for a displaceability of the spindle end with respect to two first and second spatial directions extending approximately perpendicularly to each other and each perpendicularly to the spindle axis.

Abstract: It is provided an adjusting device for a seat element of a vehicle seat, the strength structure of said seat element being connected to a guide device which substantially oriented in a first spatial direction and on which a support and a slide are arranged in a longitudinally adjustable manner relative to each other by means of a first drive device. A support lever which changes the contour of the seat element and which is hinged to the support and a toggle lever which is hinged to the slide and to the support lever via a connection joint are pivotable about axes which are oriented in a second spatial direction running perpendicularly to the first spatial direction and pivot on a plane defined by the first spatial direction and a third spatial direction running perpendicularly to the first and second spatial direction when the first drive device is actuated.

Abstract: It is provided an adjusting device of a lumbar support or a side-bolster adjuster for changing the contour or position of a seat element of a vehicle seat supporting a body part of a seat user, with at least one driving device comprising a spindle drive and at least one adjustable support element for changing the contour or position of the seat element, wherein the spindle drive comprises a spindle extending along a spindle axis, which on a fastening part of the lumbar support or the side-bolster adjuster mounted in the vehicle seat is floatingly mounted at a spindle end via a spindle holder such that at this spindle end the spindle is displaceable along at least one spatial direction extending transversely to the spindle axis.
