  • Publication number: 20100133893
    Abstract: A chair uses multiple elastic bands to form the seating surfaces. The elastic bands are held in place with a mounting bracket which facilitates easy assembly of the chair and reduces the likelihood of breakage or improper assembly of the elastic bands. The elastic bands are positioned nearly level with the chair side rails and mounting bracket, and the elastic bands cover the mounting screws to provide a chair which is more comfortable and more aesthetically pleasing.

  • Patent number: 6644146
    Abstract: A unique and simple method for attaching a steering wheel to a steering shaft includes a pair of securement members. The steering shaft is provided with a slot extending into an enlarged space. The first securement member extends across a bore in the steering wheel, and is threadably received in the second securement member. The steering wheel can be moved onto the steering shaft with the first securement member moving through the slot and into the space. The first securement member can then draw the second securement member into the space. Preferably, there is a tapered interface between the second securement member, the steering wheel, and the steering shaft. The tapered surface drives the steering wheel downwardly onto the steering shaft such that a wedge-lock is provided. In a further feature of this invention, an outer housing surrounds the steering shaft. The outer housing has a pair of spaced slots.

  • Patent number: 6431582
    Abstract: An air bag module (20) comprising: a housing (22) having a first opening (102) within a first housing portion (100), a retaining member (24) having a second opening (52) and at least one pair of opposed open faced ramps (40a,b), an air bag (26) having an inflatable cushion portion (80) and a neck portion (82), the neck portion is located between the housing and retaining member (24), a cover (30) to protect the air bag, the cover being opened by the air bag upon inflation thereof, and an inflator (28) received within the first opening from a bottom of the first housing portion (100) and into the second opening (52), the inflator including a flange (36); wherein with an edge of the inflator flange located proximate a respective open face of a ramp and the inflator rotated, the flange engages the ramps and is drawn toward the retaining member thereby sandwiching the housing and air bag therebetween.

  • Patent number: 6364341
    Abstract: An air bag (22) having: an inflatable cushion portion (30) and a neck portion (32) in communication therewith, the neck portion defines a receiving opening to receive inflation gas, received from an inflator, to inflate the cushion portion (30). The air bag is made from flexible material and a retainer member(s) (70a,b; 100) and is preferably sewn to at least a part of the neck portion to reinforce the neck portion and to reduce the flexibility of the neck portion. The invention further includes an air bag module that utilizes the above air bag. The module includes a housing and an inflator. The housing has grooves (50a,b) for receiving a first edge of a retainer member and further includes a holding member (41a,b) formed as part of a wall of the housing (24) and which is bent or crimped over to hold a second edge of the retainer member.

  • Patent number: 6357320
    Abstract: An apparatus and method for attaching as well as removing a steering wheel to and from a steering shaft. The steering wheel includes a pair of threadably mated, first and second securement members which are movable relative to one another. One of the securement members is received within a preformed, keyed slot on the top of the steering shaft. When the securement members are tighten the second securement member is moved into the slot thereby securing the steering, wheel to the steering shaft. The apparatus further includes a movable wedge which is positionable between the top of the steering shaft and a part of the steering wheel. Inward movement of the wedge urges the steering wheel and the steering shaft apart facilitating separation and removal.

  • Patent number: 4500496
    Abstract: An improved process is disclosed for the treatment of molybdenite concentrate to remove impurities, such as copper and lead therefrom. According to this process, ferrous chloride liquor is introduced into a reactor which is made of a material that can withstand leaching with the use of ferric chloride at elevated temperatures and pressures. Sodium or calcium chloride may also be added to the reactor which is then sealed and subjected to chlorination until the rise in temperature, due to the exothermicity of the reaction, produces the desired concentration of the ferric ion to leach the impurities present in the concentrate to a desired level. Upon completion of the chlorination, the molybdenite concentrate is introduced into the reactor and is leached therein. Finally, the resulting pulp is filtered and washed to obtain the desired purified product.
