  • Patent number: 6533357
    Abstract: A seat back adjustment mechanism for a seat assembly enabling a seat back to be selectively positioned in various fold-forward positions relative to a seat, and locked into at least one forward position, includes a quadrant supporting a cam plate that interfaces with a locking member to block an arm rotatably supporting the quadrant. The arm preferably includes a series of pawl teeth for selectively engaging the locking member to lock the seat back in a selected fold-forward position. Alternatively, the arm includes a corner portion or includes a link and a sector plate allowing for the locking of the seat back in a single fold-forward position, horizontal to the seat. A gear assembly is further provided to facilitate actuation of the adjustment mechanism.

  • Patent number: 6511129
    Abstract: A seat hinge assembly includes a lower support pivotally supporting an intermediate support and an upper support pivotally supported by the intermediate support. The intermediate support is selectively locked in one of two positions via a lower cam and lock pin. A pawl is pivotally supported by the intermediate support and includes a tooth portion for selective engagement with a tooth portion of the upper support. A spindle is rotatably supported by the intermediate support and is in operative communication with an upper cam. Rotation of the spindle in a first direction disengages the upper cam from the pawl, thus disengaging the teeth portions for enabling forward rotation of the upper support relative to the lower support. Subsequently, the spindle is rotatable in a second direction for disengaging the lower cam and lock pin arrangement for enabling rotation of the intermediate support relative to the lower support.

  • Publication number: 20020185904
    Abstract: A seat adjustment mechanism is provided and includes an arm defining a first locking shoulder, a sector plate rotatably supported by the arm and defining a second locking shoulder having a lock recess, a locking member selectively engaging at least one of the first and second locking shoulders, a quadrant rotatably supported by the arm and slidably supporting the locking member for locking the quadrant in one of a first and second position relative to the arm and a cam plate rotatably supported by the quadrant for selectively engaging the locking member for locking the quadrant in one of the first and second positions. In the first position the locking member is biased against the first locking shoulder and in the second position the locking member is biased into the lock recess. A gear assembly is preferably provided and operably supported by the quadrant for actuation of the cam plate.

  • Patent number: 6449768
    Abstract: A switch apparatus is used in the transmission of a redundant Cable TV (CTV) signal. The redundant CTV signal can be a symmetric split linked redundant CTV signal or an asymmetric split linked redundant CTV signal. The switch apparatus is capable of handling both the symmetric and asymmetric redundant CTV signal where primary channels are split into multiple parts. The asymmetrical splitting of the primary channels is where one part contains more channels than another part. The switch apparatus includes a plurality of switches and a monitor device to detect a failure in the split signal path before the split signals are combined to be transmitted to downstream end-users. Upon detecting a failure, the switches are switched from primary channels to secondary channels by a controller. After the signal is returned, the switches are switched back to the primary channels. A delay timer may be included in the switch apparatus to avoid incidental or temporary signal recovery.
