Patent number: 7134717Abstract: The backrest of a vehicle seat having a headrest, which may be displaced from an in-use position to a safety position by the effect of a force generation device, and which is fixed, by means of retaining elements extending into the backrest. The retaining elements may be displaced relative to the backrest, under the effect of the force generating device, by means of at least one connector guide, from a connector into a connector side block. The connector slide block is preferably lockable in the connector on the displacement from the in-use position to the safety position. One embodiment includes a rectangular connector slide block which performs a turning movement on the displacement, as a result of which the radial extent of the above relative to the connector is increased thus locking the connector slide block in the connector with a positive or non-positive fit.Type: GrantFiled: September 6, 2002Date of Patent: November 14, 2006Assignee: Johnson Controls GmbHInventors: Jan Thunnissen, Bernd Kraemer, Silvio Hartlaub

Publication number: 20050077762Abstract: In the case of a head restraint which is connected to the backrest (5) of a vehicle seat, a padded segment (9) which can be changed in position relative to the basic body (1) of the head restraint can be shifted, in the event of an accident, under the action of a force-generating device from the use position toward the seat occupant's head (10) into a safety position and can be locked therein by means of a fixing device. According to the invention, the fixing device comprises a telescope (11) which, on the one hand, is supported on the basic body (1) and, on the other hand, is connected to the shiftable padded segment (9), it being possible for the resetting forces (FR) which act on the padded element to be introduced into the telescope in a direction deviating from the telescope axis (X).Type: ApplicationFiled: February 4, 2003Publication date: April 14, 2005Inventors: Bernd Kraemer, Alfred Scholi, Jan Thunnissen

Patent number: 6643605Abstract: A method and a device for determining an enthalpy of wet steam, in particular of wet steam at an outlet of a steam turbine. A part volume flow of the wet steam is mixed with a reference gas to form a mixture, so that the liquid constituents of the part volume flow evaporate completely. An enthalpy of the reference gas and an enthalpy of the mixture is then determined by measured physical variables and an enthalpy of the wet steam is calculated from these enthalpies.Type: GrantFiled: March 24, 2000Date of Patent: November 4, 2003Assignee: Siemens AktiengesellschaftInventors: Hans-Joachim Endries, Helmut Herbig, Hans-Bernd Krämer
