Patent number: 6953124Abstract: A filter element for end face inlet formed of triangular channels which are alternately closed such that the fluid to be filtered must pass through the filter material in order to flow from the inlet side (22) to the discharge side (23). The channels are formed by alternating flat layers (17) and folded layers (18), whereby all sides of the inlet channels face a discharge channel. A particularly high filter efficiency is thereby achieved such that a large filter surface area and a high filter capacity are attained with a relatively small structural volume. The filter can be used, for example, as an air filter for various air filtration applications.Type: GrantFiled: June 20, 2003Date of Patent: October 11, 2005Assignee: Mann & Hummel GmbHInventors: Manfred Winter, Guenter Goerg, Ralf Poh

Patent number: 6629732Abstract: The invention relates to a device for adjusting a seat back (6) of a vehicle seat (4), in which a drive (9) that carries out adjusting processes is integrated. This acts on stagger gears (10, 22), with which the seat back (6) is moved within a range of inclination (13). A torsion element (24) is provided between the stagger gears (10, 22) that compensates the clearance in the stagger gears (10, 22) within a first range of adjustment (18) of the seat back (6) and functions as support for the driver motor within a further range of adjustment (19) of the seat back (6).Type: GrantFiled: January 9, 2002Date of Patent: October 7, 2003Assignee: Robert Bosch GmbHInventors: Eckard Ursel, Gerhard Genter, Manfred Winter, Walter Haussecker, Herbert Schiller, Erik Maennle, Guenter Hartz, Joerg Wolf, Werner Prohaska, Martin Steuer, Hansjuergen Linde, Uwe Neumann, Andreas Rehklau
