Patent number: 8590934Abstract: A three-point automatic belt has an offering arm, which is rotatably mounted by means of a drive, for a seat in a vehicle. A rotatably mounted offering arm is designed as a belt strap part, which is stiffened in one plane, of a belt strap, and can be deflected by means of an electromotive drive. The deflectable, stiffened belt strap part can be deflected into a forward end position, in which the belt strap is offered to a vehicle occupant, into an intermediate or boarding position and into a rearward end position in which access to a storage compartment and/or a rear space and/or a rear seat is enabled.Type: GrantFiled: December 5, 2008Date of Patent: November 26, 2013Assignee: Daimler AGInventors: Frank Fruehauf, Rolf Pemsel, Thomas Siegel

Patent number: 7497897Abstract: An air supply device for the passenger cell of a motor vehicle includes a rotating element formed in an axial suction intake region of the air-conditioning blower and upstream of the air-conditioning blower. The rotating element covers the air inlet region such that all the sucked-in drops impinge onto the element. Arranged in front of the housing wall of the air supply device are drop interception elements which are fixed lamellae of low inclination or wedge structures with acute wedge angles. The drop interception elements are inclined so that the drops impinge at an acute angle. Active water and particle (pre)-separation is thereby ensured.Type: GrantFiled: November 16, 2005Date of Patent: March 3, 2009Assignee: Daimler AGInventors: Joachim Currle, Frank Fruehauf

Publication number: 20060236662Abstract: Disclosed is a deflection chamber (1) for eliminating water in a fresh air supply system of a motor vehicle, comprising an inlet port (2) located at the top in the mounted state, an outlet port (3) that is arranged essentially at a right angle therefrom, and a drainage bottom (4) which is placed below the inlet port in the mounted state and collects and drains away water. In order to prevent drops of water, which are separated from the air, from bursting and mist from forming in said deflection chamber (1), the steeply rising lamellae of the deflection chamber are disposed in such a way that the lamellae (5-9) are aligned at an acute angle from the direction of arrival (A) of the drops of water in the free craoss section between the inlet port (2) and the drainage bottom (4) while fully covering the drainage bottom (4) in the direction of arrival (A).Type: ApplicationFiled: June 15, 2004Publication date: October 26, 2006Applicant: DAIMLERCHRYSLER AGInventors: Joachim Currle, Frank Fruehauf

Patent number: 6872135Abstract: A heating and/or air-conditioning system for vehicles, preferably passenger vehicles, has a central air-conditioning and/or air-conveying device for conditioning and/or conveying air. In order to achieve optimum air conditioning of the vehicle interior and sufficient freedom of the windows from misting with the most effective energy use possible, the air within the vehicle interior is fed so that, for example, outside air and circulating air are fed into the vehicle interior through dedicated air inlet openings and removed from the vehicle interior through dedicated air outlet openings. The air is guided on closed flow paths in order to achieve separation of circulating air and outside air.Type: GrantFiled: November 22, 2002Date of Patent: March 29, 2005Assignee: DaimlerChrysler AGInventors: Joachim Currle, Frank Fruehauf, Florian Kauf, Juergen Maué , Juergen Wertenbach

Patent number: 6823685Abstract: A vehicle air-conditioning device having at least one control element which supplies a prescribed value to the air-conditioning control unit, a state of flow being provided by an air speed and a degree of turbulence of the air, which can be influenced by the strength of the fan, distribution of air to the discharge nozzles, the discharge direction to the discharge nozzles and further actuators which have an effect on the state of flow, and a thermal state is provided by the temperature distribution and effect of radiation in the vehicle interior. Provision is made for the at least one control panel to be used to prescribed a state of flow desirable for the occupant and a thermal state.Type: GrantFiled: August 14, 2002Date of Patent: November 30, 2004Assignee: DaimlerChrysler AGInventors: Frank Frühauf, Dieter Heinle, Jürgen Maue, André Strobel

Patent number: 6805624Abstract: An air outlet nozzle of a heating and/or air-conditioning system of a vehicle is provided. It has a displacer which is connected to a nozzle mouth element mounted displaceably in the nozzle housing. In order, with as little structural space as possible and as little flow losses as possible, to be able to control the diffusivity of the air jet emerging from the air outlet nozzle, the flow resistance and the axial position of the displacer can be adjusted.Type: GrantFiled: May 2, 2003Date of Patent: October 19, 2004Assignee: DaimlerChrysler AGInventors: Joachim Currle, Frank Fruehauf

Patent number: 6390256Abstract: A springing system for a vehicle has a hydraulic actuator and a storage element which holds hydraulic fluid. The system is constructed as a gas accumulator with a holding chamber for the hydraulic fluid and a separate gas chamber, and communicates with the actuator via a connecting line. In order to construct a hydropneumatic springing system for vehicles with a largely linear spring behavior up to complete relief of the load, a further storage element is connected to the actuator via a connecting line and is constructed as an elastomeric accumulator.Type: GrantFiled: October 17, 2000Date of Patent: May 21, 2002Assignee: DaimlerChrysler AGInventors: Frank Fruehauf, Ruediger Rutz

Patent number: 6037731Abstract: A method is provided for adapting the side support, as a function of the driving situation and driving styles, of a person sitting in the seat of a vehicle, in which method a lateral acceleration acting on the seat is determined as reference variable for the adaptation. In order to allow greater allowance for the way in which the sitting person senses lateral acceleration, as well as a comfortable sitting sensation with the advantages of a necessary side support which is built up in curves at short notice, the specific instantaneous lateral acceleration is weighted with the instantaneous driving speed of the vehicle. A control variable for the degree of adaptation is derived therefrom. In addition, a supplementary control variable is determined which brings about support of the driver on both sides in the seat as a function of the driving style. A vehicle seat in which this method is applied is specified.Type: GrantFiled: November 13, 1998Date of Patent: March 14, 2000Assignee: DaimlerChrysler AGInventors: Frank Fruehauf, Helmut Gimmler, Klaus-Peter Kuhn, Werner Reichelt, Helge Schmidt-Spalding, Timo Schneider
