Patent number: 9744887Abstract: A seat having a backrest and a seat cushion includes rows of adjusting elements, respectively, which adjusting elements are arranged above one another, on both sides of the longitudinal center plane of the seat. By alternately applying the adjusting elements mutually arranged in a vertically staggered manner in the two halves of the seat, a rotational movement can be actively applied to a seat user's back and possibly pelvis, which rotational movement corresponds to the rotational movement of the back, and possibly of the pelvis, when walking.Type: GrantFiled: October 17, 2008Date of Patent: August 29, 2017Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Alexander Durt, Rudolf Lein, Matthias Franz

Patent number: 8616654Abstract: A method and a device for adjusting a seat are provided. The method includes the acts of detecting a pressure exerted by a user on the seat via a pneumatic sensor and/or a hydraulic sensor, and adjusting the seat based on the pressure exerted by the user. The device includes a pneumatic or hydraulic lifting element, a pneumatic or hydraulic pressure sensor connected to the lifting element, and a control unit connected to the pressure sensor. The pressure sensor detects a pressure exerted by a user on the seat, and the control unit controls the first lifting element to adjust the seat based on the pressure exerted by the user.Type: GrantFiled: May 7, 2010Date of Patent: December 31, 2013Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Raphael Zenk, Matthias Franz, Alexander Durt, Rudolf Lein

Patent number: 8038222Abstract: An actively ventilated vehicle seat includes a lower air-impermeable seat cushion or backrest part, an air-permeable intermediate layer made of a spacer fabric and an upholstered cover. The vehicle seat is divided into upholstered areas which are delimited from each other by seams anchored at the air-impermeable seat cushion. Air bridges are provided which extend transversely to the seams for connecting the intermediate layer between the individual upholstered areas. An unobstructed seat ventilating system and a permanently secure attachment of the seams are achieved in a simple manner in terms of production and without affecting the seating comfort in that the air bridges are integrated all around into the air-impermeable seat cushion and the seams are anchored above the air bridges in the air-impermeable material of the upholstered part covering the air bridges.Type: GrantFiled: April 2, 2009Date of Patent: October 18, 2011Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Rudolf Lein, Christian Pudenz

Patent number: 6398303Abstract: The seat cushion of a seat can be tilted about its longitudinal center axis for generating a tilting movement of the pelvis of a seat occupant. For generating the tilting movement, an adjusting element is provided in each of the right and the left area of the seat cushion. The adjusting elements interact to cause an opposite adjusting movement in the vertical direction, whereby the tilting movement of the pelvis is achieved. The adjusting elements are constructed, for example, as liquid-filled rolling bellows, in which case a sliding vane rotary pump changes the volume of the two adjusting elements in a diametrically opposed manner.Type: GrantFiled: May 5, 2000Date of Patent: June 4, 2002Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Wolfgang Herrmann, Peter Beerbaum, Josef Leitner, Rudolf Lein, Erhard Moser, Ralf Dietz, Juergen Schreiner, Ludwig Faerber

Publication number: 20020021038Abstract: A seat, in particular a motor-vehicle seat, having a seat-adjusting mechanism is described. The seat-adjusting mechanism comprises a motor-driven spindle unit with a nut which has an inner profiled portion and a spindle which has an outer profiled portion. The spindle unit comprises a plurality of rollers which are arranged in planetary manner between the nut and the spindle and cooperate with the nut and the spindle. Each of the rollers has at least one outer profiled portion.Type: ApplicationFiled: July 12, 2001Publication date: February 21, 2002Inventors: Rudolf Lein, Siegfried Angerer, Bernd Gombert, Markus Grebenstein
