  • Patent number: 5226672
    Abstract: A protection system for an occupant seat in a vehicle has a net stored in the headliner above and forward of the front seat. The net is secured at its four corners to cables that are trained along the inside of the vehicle to a pair of pistons in barrels that are located beneath the vehicle. A sensor electrically triggers firing of charges that propel the pistons in the event of a vehicle crash in a wide angle frontal plane. The pistons tension the cables to deploy the net across the front (and sides) of the occupant seat to restrain movement of any occupants in the seat. The cables are latched to maintain the net in its deployed position. A quick release mechanism enables an occupant to release the net after a crash impact or series of crash impacts. Additional protection systems may be provided for additional occupant seats in the vehicle.

  • Patent number: 5041253
    Abstract: A method of manufacturing a composite camshaft having a shaft positioned within appropriately aligned and fixtured annular cam and bearing elements, each having interior protrusions that increase in size toward the tube axis. The shaft and elements are supported in a mold and a flowable, hardenable material is injected to fill the space between the tube and the elements for securing the elements to the shaft. The protrusions enhance the grip of the plastic with shrinkage. The shaft and the cam elements have nesting configurations that form a continuous space therebetween such that the hardened material compressionally resists torsional forces between the shaft and cam elements. Injection molding is performed without substantially stressing the freely supported shaft and without applying undue strain to the elements by providing undercut portions in the mold surrounding part of the exterior surface of the elements with high pressure plastic during injection.

  • Patent number: 4977793
    Abstract: A plastic stabilized composite camshaft and method. In one version, a hollow polished tube is positioned within appropriately aligned and fixtured annular cam elements having interior protrusions that increase in size toward the tube axis and a flowable, hardenable material is injected through the tube to fill the voids between the tube and the cam elements for securing the cam elements to the tube. The protrusions enhance the grip of the plastic with shrinkage. The surfaces of the tube and of the cam elements are preground to finish dimensions. In another version, the annular cam elements are originally circular and formed into their final configuration in the mold by appropriately configured side acting shuttles. In a preferred embodiment for automotive applications, the shaft and cam elements have nesting configurations that form a continuous space therebetween such that the hardened material compressionally resists torsional forces between the shaft and cam elements.
