  • Publication number: 20050248169
    Abstract: A low profile floor console for a vehicle includes a pair of end walls. In a lowered position, the console permits pass through between two spaced apart vehicle seats. When raised, fabric or netting attached, together with the end walls define a storage area. In the preferred embodiment, an add-on module fits over the raised end walls to provide a rigid storage area, and additional functionality, such as a tray, a power port, cup holders, change bins, and the like. The lid of the module may be configured for sliding or pivotal movement to allow access to the interior thereof. Also in the preferred embodiment, the floor console is constructed to trim out a parking brake assembly. In various alternate embodiments, the floor console end walls may be constructed to provide additional functionality, such as internal map pockets, and the console system may be arranged for use at different locations within the vehicle, such as in the cargo area.

  • Patent number: 6467547
    Abstract: The present invention generally provides a running tool comprising a torque-dampening system. A first portion and a second portion of the running tool are operably related by a torsion interface. In one embodiment, the torsion interface includes a plurality of interlaced teeth disposed on the each of the first and second portions. During relative rotation of the first and second portions, the teeth engage and “ride up” on one another, thereby forcing the first and second portions in opposite axial directions. At least one of the portions houses a flow restrictor assembly adapted to restrict fluid flow from one region to another during the axial movement of the portions. Accordingly, the relative rotation between the portions is inhibited, or dampened.
