  • Publication number: 20050189802
    Abstract: A vehicle passenger seat mixed passive/active occupant restraint provides a two element seat back frame. A first frame element provides for energy absorption from a seat belt fitted to a passenger in the vehicle passenger seat. The second frame element absorbs energy from an unrestrained passenger impacting thereon. The first frame element may be mounted forward from, or nesting, the second frame element.

  • Publication number: 20050189799
    Abstract: The invention involves shifting the location of the seat belt retractor in order to reduce the thickness of the seat especially in the lower regions for a mobile vehicle seat. The seat may be used for a mobile vehicle as a school bus as well as for automotive applications. The seat belt retractors are attached to a portion of the seat structure that allows the webbing to exit the retractor on the front surface of the seat back. The webbing is then allowed to cross over to the rear surface of the seat back as it rises to the turning-loop. The retractor may be located forward of the seat back pivot point on the seat frame in order to allow for the webbing to exit on the front surface of the seat back.

  • Publication number: 20050184577
    Abstract: The invention provides a seat for a bus that has a movable front frame or seat back that a seat occupant rests his or her back against normally. The front frame is the mounting point for the upper portion of a three-point seat belt. The seat frame contains a rear passenger support wall or rear frame to protect a passenger of rearward seat from moving out his safety zone in a forward direction in the event of a rapid deceleration. The rear frame is part of the seat frame and only moves upon initial contact by a rearward-unbelted passenger impact. A rotation guide slot defines the amount of rear frame movement. The front frame is limited in the amount of its forward pivoting movement by a tether, spring or fluid dampener that is engaged to an immovable portion of the frame and thereby limits forward travel of the front frame.

  • Publication number: 20050161026
    Abstract: A method for controlling a fuel metering system of an internal combustion engine. A activation duration of at least one electrically operated injector determines the injected fuel quantity. The minimum activation duration during which fuel is only just injected being determined in certain operating states. The activation duration being increased/reduced starting at an initial value, and the activation duration during which a signal undergoes a change being stored as the minimum activation duration, in which the difference between the activation duration during which a signal undergoes a change and the stored minimum activation duration is determined, from which correction values for the fuel quantity map of the injector are determined and stored using at least one transfer function, which characterizes the relationship between the minimum injection and activation durations at several test points of the injector and/or the relationship between the activation durations at different test points of the injector.

  • Patent number: 6823846
    Abstract: The fuel injection device has a high-pressure pump that supplies highly pressurized fuel to at least one high-pressure reservoir connected to injectors disposed in cylinders of an engine, wherein the injectors are connected to a common low-pressure reservoir. A pressure holding valve maintains a predetermined low pressure in the low-pressure reservoir. A pressure regulating valve regulates the pressure in the high-pressure reservoir by diverting fuel from the at least one high-pressure reservoir through a diversion connection into a low-pressure region. The diversion connection of the pressure regulating valve is connected to the low-pressure reservoir so that the low-pressure reservoir is filled with fuel.

  • Patent number: 6719264
    Abstract: The invention relates to a valve for controlling fluids, having an actuator unit for actuating a valve member which has a first piston and a second piston, separated from it by a hydraulic chamber, and which actuates a valve closing member that divides a low-pressure region at system pressure from a high-pressure region. For leakage compensation, a filling device connectable to the high-pressure region is provided with a hollow chamber, in which a throttle body is disposed such that a line leading to the high-pressure region discharges into the hollow chamber on one end of the throttle body, and on the other end a system pressure line leading to the hydraulic booster branches off. The system pressure is built up as a function of the prevailing pressure in the high-pressure region, by means of geometrically defining the throttle body, a gap surrounding it, and the dimensions of the piston along which the system pressure is reduced.

  • Patent number: 6705551
    Abstract: The invention relates to a common rail fuel injector having an injector housing with a fuel inlet in communication with a central high-pressure fuel reservoir outside the injector housing and with a pressure chamber inside the injector housing. A control valve assures that a nozzle needle lifts from a seat when the pressure in the pressure chamber is greater than the pressure in a control chamber that communicates with the fuel inlet via an inlet throttle. The control chamber is defined by a bush that is displaceable, causing a sealing action, on the end of the nozzle needle remote from the combustion chamber and that is kept in contact against the injector housing with the aid of the nozzle spring.
