  • Patent number: 6199900
    Abstract: A vehicle safety collision headrest system which substantially instantaneously moves a headrest of a seat from any manually adjusted position to a fully extended position. The system includes a pressure actuation assembly having combustible propellant or fluid tank fluidly connected to a cylinder. The cylinder is rigidly connected to a bottom of the headrest and upon the occurrence of a collision or abrupt stopping the pressure actuation system fires the cylinder upwardly which causes the headrest to extend to a properly adjusted position behind a passenger's head and neck. The pressure actuation system inflates a front airbag which extends between a bottom of the headrest and a top of the seat to fill the gap therebetween. The front airbag cushions the passenger's head and neck as the passenger is thrust rearward and protects the passenger's head and neck from contacting the cylinder and poles rigidly mounted to the bottom of the headrest.

  • Patent number: 6196083
    Abstract: A pivoting handle assembly having weight compensation which is anticipated to be used in conjunction with parts, part handling fixtures and other materials to reduce the apparent weight of the pivoting handling assembly having weight compensation to an operator and thereby reduce operator fatigue. In particular, an elongated spring member is positioned in the interior of an elongated pivoting arm member to at least partially compensate for the apparent weight to an operator of the pivoting handle assembly having weigh compensation being supported, transported and/or positioned thereby. As elongated pivoting arm member is rotated in a first rotational direction, a chain is wrapped around the center diameter of a pivot portion between the elongated pivoting arm member and a stationary arm member and a pin is pulled to compensate for the change in length, thus compressing the elongated spring member.

  • Patent number: 6183387
    Abstract: The present invention relates generally to hydraulically actuated limited slip differentials. More particularly, the present invention relates to a hydraulic limited slip differential which utilizes a variable pressure relief check valve used to vary the maximum hydraulic pressure available within the differential case in a manner that the limited slip feature can be adjusted anywhere between a full “ON” and a full “OFF” configuration. Hydraulic fluid will not flow through the check valve until the hydraulic pressure within the case results in a reaction force larger than the check valve activation pressure, thus providing a maximum pressure limit in the hydraulic system. The activation pressure of the check valve can be selectively controlled by an actuator. The movement of the actuator corresponds to a change the retaining force of the check valve. Dynamic control of the system in response to vehicle operational parameters may also be performed.
