  • Patent number: 7575088
    Abstract: A powertrain mounting system includes a pair of engine and transmission mount assemblies. The engine mount assemblies include an isolator assembly having an elastomeric bushing with an encapsulated mounting member, an integral snubber, and a bracket assembly having a one piece can arranged to house the bushing and having an interlock arranged to engage the bushing. The bushing is press-fit into the can and arranged to isolate the mounting member from the can thereby dampening powertrain vibration and controlling powertrain movement, and the snubber is arranged to limit movement of the bushing relative to the can. The transmission mount assembly includes a support member, a pair of isolators positioned relative to each other, and a pair of mounting brackets positioned on the isolators; wherein the isolators are arranged to maintain the mounting brackets in spaced relation to the support member thereby dampening powertrain vibration and controlling powertrain movement.

  • Publication number: 20030061677
    Abstract: A vehicle wiper system is provided including a cross-vehicle shaft that drives a pair of actuation mechanisms for driving a pair of wiper assemblies. The actuation mechanisms each include a crank, a connecting rod and a lever arm, whereby the connecting rod operably interconnects the crank and lever arm. The lever arm is fixed for rotation with a wiper post, which is in turn fixed to the wiper assembly. The actuation mechanism drives reciprocal rotation of the wiper post, thereby driving reciprocal sweeping motion of the wiper assemblies. The cross-vehicle shaft is driven by a motor that is controlled by a controller.

  • Patent number: 4909571
    Abstract: An inertia sensitive latch assembly particularly adapted for preventing forward dumping of a motor vehicle seat back. The embodiments are particularly suited for applications in station wagon vehicles having forward dumping capability of the second passenger seats. The device is enclosed within the seat back and includes a pendulum engageable with a latch hook affixed to a support structure. The pendulum engages the hook when the vehicle is subjected to deceleration loads above a predetermined level. In one embodiment of the invention, a retention clip device is provided which maintains the pendulum engaged with the latch hook after a deceleration load is relieved to maintain the seat in engagement throughout multiple impact vehicle conditions. Both embodiments are substantially enclosed within the seat back cushion structure, thus protecting them and providing an unobstructed load floor when the seat back is dumped forward.
