Abstract: A kit (10) for removal of bone (12) from a patient to prepare a bone cavity (14) for receiving a joint prosthesis (16) is provided. The kit (10) includes a guide (20) for cooperation with the bone (12) and a rotatable tool (22). The tool (22) is constrainable by the guide (20) for removal of the bone (12). The guide (20) includes a first portion (24) thereof cooperable with the tool (22) and a second portion (24) thereof cooperable with the bone (12).

Abstract: An airbag door construction for airbag deployment comprising a hard instrument panel having a weakened area outlining at least a portion of an integrally molded airbag door. A reaction plate is attached to the underside of the panel at the airbag door location. A deployment chute is molded with the reaction plate and attached to the hard instrument panel just outboard of the outline of the airbag door. A tether is included that engages with the reaction plate whereupon airbag deployment the tether allows the airbag door/reaction plate welded combination to break loose from the hard instrument panel in a controlled manner.

Abstract: A wheelchair includes a support frame and wheels and casters rotatably cocted to the support frame. A rotatable steering member is slidably connected to a caster swivel support frame for steering the wheelchair. The wheelchair also includes a collapsible seat frame as well as a pedal operated transmission to drive the wheels of the wheelchair. A single brake lever brings two brake elements into engagement with the wheels to lock the wheelchair against rolling movement.

Abstract: An interior trim panel for a motor vehicle has an opening for deployment of an air bag and a discrete air bag door that is attached to the interior trim panel for closing the opening and for being opened by an air bag when it is deployed. The door includes a retainer that hinges the door to the trim panel and a covering that includes a frangible flap at an end of the retainer that holds down an end of the door and breaks away when the air bag is deployed. An alternate interior trim panel has another discrete air bag door that includes a bracket attached to the retainer for establishing the location of the hinge line. Another alternate interior trim panel arrangement has an integrated or invisible air bag door that includes a bracket attached to the retainer for establishing the location of the hinge line in an invisible door arrangement.

Abstract: An air bag door arrangement is incorporated in an instrument panel that has a substrate and an uninterrupted covering for the substrate. The substrate includes an air bag opening that is closed by a door. The door has a hinged end that is clamped to the substrate by a frame that is beneath the substrate, a reinforcement bar that is above the substrate and a plurality of fasteners that force the frame and reinforcement bar toward each other. An air bag canister is attached to the frame beneath the air bag opening of the substrate and the frame is attached to automotive body structure so that the substrate is isolated from the reaction forces of the canister when an air bag housed in the canister inflates and pushes the door through the instrument panel covering.

Abstract: An unshielded buried service wire (20) includes a core (22) and a jacket (40). The core comprises two pairs (24-24) of insulated metallic conductors (26-26). Also associated with each conductor pair is a longitudinally extending waterblocking member (33) which inhibits the flow of water longitudinally of the wire. The jacket has a transverse cross sectional configuration which is generally oval. Adjacent to each of opposed small radius of curvature portions of the service wire and embedded substantially in the jacket is a longitudinally extending, rod-like strength member (50) which is caused to adhere to plastic material of the jacket.
