  • Patent number: 7699401
    Abstract: An anchor for securing seat belt component to a vehicle includes a latch member for securing a tongue portion of the component within a housing. The latch member is movable between a first position wherein a protrusion on the latch member engages the tongue and a second position wherein the protrusion is displaced for releasing the tongue. A biasing member provides a biasing force to maintain the latch in the first position. The housing includes a latch-access area for allowing the latch member to be engaged for manually forcing the latch member to the second position to allow the tongue portion to be removed, so that the anchor does not have a release button.

  • Patent number: 7543363
    Abstract: A seat belt buckle for use with a tongue of a seat belt, the seat belt buckle comprising: a frame portion; a latch being movably mounted to the frame portion for movement between a first position and a second position, the latch being configured to engage a portion of the tongue as the latch moves from the first position to the second position; an ejector being slidably mounted to the frame portion for movement between a locking position and a release position, wherein movement toward the release position causes an opening force to be applied to the latch in order to move the latch from the second position towards the first position, wherein movement of the ejector towards the release position is caused by movement of a release button movably mounted to the seat belt buckle; an inertia locking device rotatably mounted to the release button for movement between a blocking position and an unblocking position, the inertia locking device being configured for rotation in a plane substantially parallel to a plane o

  • Patent number: 7370393
    Abstract: A seat belt buckle for use with a tongue of a seat belt includes a latch that engages the tongue, and a release bar that releases the latch. An inertia locking device mounted to a frame portion is normally biased in an unlocking position and rotates to a locking position to prevent movement of the release bar into the release position when the seat belt buckle is subjected to a force greater than the biasing force.

  • Patent number: 5616293
    Abstract: A structural prototype of the component part is made by first creating a model of the part which is of cured resin and has a network of interconnected supporting members defining the shape of the part and leaving channels between the supporting members to drain away uncured resin from the model. A hardenable structural material is infiltrated into the channels of the model and cured so that the resin model has become reinforced to provide a structural model of the component part. The hardenable structural material may be a mixture of powdered graphite and resin which is cured by heat. The heat may be sufficient to both cure the hardenable structure material and burn away the cured resin of the model so that the component part is then comprised of the hardened structural material having a network of channels therein where the cured resin of the model has been burned away. The model can then be further strengthened by filling the network of channels with a suitable hardenable material.

  • Patent number: 5364252
    Abstract: A gas injector having a retractable nozzle with linear gas feed passage therethrough for a gas assist plastics injection molding machine. The injector interfaces with the injection molding tool and has a nozzle with a tip that, in a forward position, protrudes through a port therein leading into the tool cavity or a runner system leading into the cavity for gas injection during molding. The nozzle tip is connected by a nozzle body to a base that is operatively mounted in an actuator housing. The base is connected to an in-line gas routing extension of the nozzle that projects through the outer cover of the housing. The extension is coaxial with an internal spring that seats on the base and holds the nozzle tip in a gas injection position resisting the force of plastics injection pressure.

  • Patent number: 5342191
    Abstract: Gas transmission plugs are placed in a supporting strip portion in plastics injection mold tooling so that an appropriate gas assist injection location can be readily selected, and mated, with a gas injection nozzle thereby eliminating the requirement for pre-drilling mold tooling with gas injection points and removing the tooling from the press so that a gas injection nozzle can be installed relative to the selected injection location. The plugs can be made from porous metal or ceramic with pores that are so small that plastics cannot enter the plug to cause pore clogging. Also, linear gas transmitting passages can be laser beam drilled through plugs of steel or other material with diameters that are sufficiently minute to prevent entry of plastics melt and resultant clogging.

  • Patent number: 5308129
    Abstract: A mounting panel of stamped steel has the door hardware such as the window regulator and door handles fixedly mounted thereon to facilitate preassembly and shipping. The mounting panel is subsequently mounted on the vehicle door. A door latch is provided for latching the door in the closed position and a retainer means is provided acting between the mounting panel and the door latch to loosely connect the door latch to the mounting panel for convenience of preassembly and shipping. The retainer means is a molded plastic retainer having integral projections which are force fit into plurality of openings provided in a door latch. The retainer means also has an integral headed prong structure which is loosely retained within an opening in the mounting panel with the aperture being oversized with respect to the headed prong to thereby permit adjusting movement of the door latch relative to the mounting panel.

  • Patent number: 5146712
    Abstract: A power window assembly for a rear window opening of a truck cab has a pair of stationary window panes spaced apart and securely mounted in the rear window opening and defining therebetween a center window opening. First and second movable window panes are slidably located in the rear window opening and adapted for sliding movement toward each other to a closed position where the panes abut each other closing the center window opening and away from each other to an opened position overlying at least a portion of the stationary window panes thereby opening the center window opening. A reversible electric motor has a primary drive gear for generating rotary motion of the primary drive gear. A tape having a plurality of slots engaging and driven by the primary drive gear is connected to the first movable window so that the first movable window pane moves between the closed position and the opened position.

  • Patent number: 5086586
    Abstract: A vehicle door assembly has a framed door and a window which is movable between open and closed positions. The window is biased outwardly toward an outer flange on the framed door by a first seal and is guided via pin guides secured to its side lower end by guide channels which include outwardly curved upper guide track sections which are supported for limited movement relative to the stationary lower guide tracks. The upper curved guide track sections are movable by the pin guides as the window approaches its closed position so the window will be substantiallly flush on all four sides with the door frame and outer door panel and thus this flushness is achieved irrespective of the tolerance variatons in the height of the frame and window.
