The mechanism (72) is controlled by an electric motor (70).

Abstract: A method of molding a plastic shell having an outer pliable skin layer and a foam backing layer comprises casting a first skin layer portion from wear resistant material in a first casting sequence for those areas of the panel susceptible to high wear and in a second casting sequence casting self-skinning foamable material against the remaining portion of the mold surface and over the first-cast skin layer portion to develop, simultaneously, the remaining outer skin layer portion of the shell and a foam backing layer which extends across the entire skin layer.

Abstract: A mold press includes an upper mold carrier mounted to slide up and down along an upright mold press frame and to rotate about a horizontal rotation axis. The mold press frame is supported on a mold press base to tip forward and aft about a horizontal upper mold pivot axis disposed parallel to and below the rotation axis. A lower mold carrier is supported on the mold press base below the upper mold carrier and above the upper mold pivot axis. The lower mold carrier includes a lower mold mounting plate that is pivotally supported on the mold press base for tipping motion along a hinged edge about a lower mold pivot axis that lies parallel to and below the rotation axis and above the upper mold pivot axis.

Abstract: A slide bearing has a bearing bore for accommodating a shaft acted upon at least temporarily by a radial force. At least one bearing end of the slide bearing has at least one chamfer for preventing a contact between the shaft and the slide bearing and/or for facilitating the supply of the slide bearing with lubricating medium. In a preferred embodiment, in which the radial force acts essentially in a predetermined direction onto the shaft, at least one chamfer is provided on an unstressed side created because of the predetermined force effect, which chamfer is larger than a chamfer on a stressed side situated opposite the unstressed side. By means of the chamfer or chamfers, the danger of contact on the unstressed side caused by a bending of the shaft is reduced and the supply of the slide bearing with lubricating medium is increased without significantly reducing the bearing length on the stressed side which essentially carries the bearing load.

Abstract: A carbon-segment face commutator assembly for an electric motor includes an annular array of copper conductor sections stamped from a single copper blank. The annular array is overmolded with an electrical-conducting resin-bonded carbon composition which mechanically interlocks the conductor sections and defines a circular commutating surface. During overmolding, radial grooves are formed in a bottom surface of the carbon overmold opposite the commutating surface. An annular hub is then formed by overmolding an insulator material around and under the carbon overmold and the conductor section array. The hub insulator material flows into the radial grooves of the carbon overmold and leaves only the circular commutating surface exposed. The carbon overmold is formed into an annular array of eight electrically-isolated carbon segments by machining radial slots inward from the commutating surface of the carbon overmold to the underlying radial grooves.

Abstract: A discrete air bag tear seam is provided in the finishing cover of an interior component of an automotive vehicle. An applique installed on the cover has an elongated external decorator head concealing the tear seam. Elongated and laterally spaced retention flanges of the applique stabilize and releasably retain the cover at the tear seam. The applique is secured to a fixed retainer part of the component and operates by releasing the cover at the tear seam to form an air bag door in response to the forced outward movement of an underlying door substrate on air bag deployment. The underlying door substrate exerts a force on the cover and particularly the outer skin thereof and causes it to pull away from the applique starting at the concealed tear seam to establish an opening for improved air bag deployment.

Abstract: A molded motor vehicle instrument panel made of a thermoplastic material has an integral air bag deployment door for a passenger side air bag that is defined by a tear seam and is normally retained by an integral flexible mounting/hinge flange to a part of the vehicle structure when the seam is torn by the inflating air bag and wherein this flange then bends to allow the door to swing open to allow deployment of the air bag through an opening in the instrument panel while retaining same to the vehicle structure as the door is then free of the instrument panel. At very low temperatures, a portion of the air bag door can break away from the mounting/hinge flange because of plastic embrittlement at these low temperatures and the high bending stresses encountered at this juncture.

Abstract: A skin for an automotive interior panel has a main body portion for covering most of the panel and an air bag cover portion for covering the panel portion that the air bag deploys through. Casting a first plastic material against a first portion of a heated mold surface forms the main body skin portion. Casting or spraying a plastic material against a second portion of the heated mold surface forms the air bag cover skin portion. The mold surface portions may be confined from one another by a partition or by masking one portion while casting against the other. The main body and air bag cover skin portions include adjacent edges that extend along the air bag cover portion periphery. The two skin portions are joined together along their adjacent edges while still on the heated mold. An air bag deployment tear seam is formed by first casting a tear seam gap in the cover portion then spraying or casting a relatively weaker material into the gap.
