  • Patent number: 4865349
    Abstract: A vehicle having an air suspension system including air bags supporting the rear cargo area thereof, a deflation control system with automatic reinflation and control reset for manually actuated lowering of the rear cargo area to the minimum height to facilitate loading and/or unloading to the ground. A manually operable control valve delivers an air pressure signal from a source to an inversion valve to exhaust the air from the air bags. A normally open electrically operated air solenoid is interposed between the control valve and the air supply and shuts off air flow to the control valve when the ignition switch is activated to restore air pressure to the air bags. The driver/operator can control the system only when the ignition switch is deactivated. Thus the system provides for operator actuable deflation and automatic reinflation and control reset.

  • Patent number: 4858952
    Abstract: A door checker which can be advantageously utilized for driving automotive equipment such as a seat belt reacher system in synchronization with the opening and closing action of the vehicle door. By appropriate arrangement of a spring and a taper in the door checker member, the force required to open and close the door is not unduly increased. By proper arrangement of the spring, the side thrust from the door checker member is always directed in one direction, whereby the structure for supporting the side thrust is simplified.

  • Patent number: 4856613
    Abstract: Method and apparatus for disabling an automobile powered by an engine utilizing an automatic transmission with a gear selector movable between non-drive and drive positions. After the engine is started up with the gear selector in a non-drive position, the movement of the latter into a drive position initiates a timer to deliver a signal for a predetermined period of time such as 15 seconds. That signal is employed to disable the engine within the vehicle if during that period an acceleration or throttle measuring device indicates that excessive acceleration is occurring or that a seat sensor device indicates that the driver is not present. Acceleration is measured by sensing intake manifold pressure or throttle position.

  • Patent number: 4854409
    Abstract: A control system for a lift axle suspension wherein two or more axle suspensions are mounted on a vehicle frame and a liftable axle is automatically raised or lowered depending on the load on another of the axle or axles. An override to the automatic lift system is provided when the vehicle is fully loaded to lift a liftable axle selectively for a limited, relatively short period of time to assist in maneuvering the vehicle. The control system detects the load on one axle and automatically raises the second axle to the raised position when the load on the first axle is below a first predetermined value and automatically lowers the second axle to the lower position when the lower load on the first axle is above a predetermined value which is greater than the first predetermined value. A delay is provided in the operation of the control system to lower the second axle upon the detection of the load on the first axle to compensate for road bumps.

  • Patent number: 4852680
    Abstract: An anti-theft security system for an off-road vehicle is disclosed. The system includes a master control module, which may be part of the vehicle's instrument cluster, and a remotely located security module, which is directly adjacent to at least one electrically-operated actuator of the vehicle normally operated as part of transporting the vehicle to another location. The security module includes a tamper-resistant housing which obstructs physical access to at least part of the actuator. The master module, which may include a microprocessor and LED display, has an operator interface such as a keypad for entering a first access code known only to authorized operators of the vehicle. When the sequence of entered keystrokes matches the first access code stored within the master module, the module automatically generates and transmits to the security module a signal containing a second and different access code.

  • Patent number: 4842296
    Abstract: In a four-link parallel link vehicle suspension system, a generatrix or an imaginary king pin is defined as a line connecting an instantaneous center of rotation of the knuckle as defined by an upper pair of lateral links with another instantaneous center of the rotation as define by a lower pair of lateral links and the range of the intersection of the imaginary king pin with the tread contact surface is minimized for the purpose of reducing the change in the force required to maintain a certain steering angle of the wheel. Thereby, the handling of the vehicle is improved through the reduction in change in the force required to maintain a steering angle of the wheel while maintaining the freedom of parameter setting which is intrinsic to the four-link parallel link vehicle suspension system.

  • Patent number: 4842093
    Abstract: A system and method for preventing unauthorized starting of a motor vehicle. A timing interval of preselected duration is generated only upon detecting positioning of an ignition switch to a first position by means of a proper key inserted into the vehicle ignition switch. An electrical indication is generated when the ignition switch is positioned to a second position which, in one embodiment, corresponds to a start position of an automobile ignition switch. A starting circuit interrupt element remains in or is urged into a normally closed state to electrically complete the starting circuit only when the electrical indication appears during the time interval. The starting circuit may thereby only be energized for starting the motor during a normal preselected starting sequence comprised of key insertion followed by positioning of the switch from the first to the second state within the preselected time interval.

  • Patent number: 4842300
    Abstract: A structure and assembly technique for providing an internal reinforcement for an air bag module to restrain bulging of the module while minimizing the size of the module. The air bag module comprises a container with a wall defining a cavity for a gas generator and at least a part of an air bag. The wall also defines an opening through which at least part of the bag is inserted into the cavity. A reaction member, preferably a fabric tether strap, is connected with at least two points of the wall adjacent the container opening and extends across the opening in the container. The tether strap is located internally of the container and resists deformation of the container under the pressures of air bag deployment, without increasing the size of the module. The tether strap is preferably constructed as a part of the air bag itself, and is incorporated into the container at the time the air bag is assembled with the container.

  • Patent number: 4840396
    Abstract: A rear suspension system for automobiles, comprising: a trailing arm pivoted to the automobile body at its front end and to a knuckle at its rear end; a first and a second lateral links extending laterally across an upper portion and a lower portion of the knuckle and the corresponding locations of the automobile body, respectively; and a third lateral link extending laterally across an intermediate position of the knuckle, located between the upper portion and the lower portion of the knuckle and behind a central axial line of a wheel axle of the knuckle, and the corresponding location of the automobile body. The second lateral link has a substantially same length as the third lateral link. Thus, the mounting positions of the lower end of the shock absorber can be lowered, and the resistance against the changes in the toe angle and the camber angle is increased.

  • Patent number: 4840394
    Abstract: A vehicle is provided which maintains a substantially constant weight, and therefore traction, on all wheels, despite one wheel moving considerably higher or lower than the others, while avoiding a very soft spring suspension. The vehicle includes a chassis or body to be supported and a pair of side suspensions at either side of the body. In a six wheel vehicle, each side suspension includes a middle wheel, and front and rear linkages repectively coupling the front and rear wheels to the middle wheel. A body link pivotally connects the front and rear linkages together, with the middle of the body link rising or falling by only a fraction of the rise or fall of any of the three wheels. The body link pivotally supports the middle of the length of the body.
