Abstract: A system and method for post-treatment of a hollow body molding produced in an injection molding mold. A receiving finger is provided with a first end and a second end. The receiving finger is designed that it can engage into the hollow body molding. The outside shape of the receiving finger substantially corresponds to inside shape of the hollow body molding so that the receiving finger (5) can hold the hollow body molding. Preferably, the outside diameter of the receiving finger is substantially equal to inside diameter of the hollow body molding in a cooled condition so that the hollow body molding can be removed from the receiving finger even after shrinkage. Desirably, the outside diameter of the receiving finger is between about 0.01 mm and about 1 mm and preferably about 0.1 to about 0.5 mm smaller than the inside diameter of the hollow body preform in the removal condition so that the hollow body molding can be removed from the receiving finger even after shrinkage.

Abstract: A vehicle seat headrest with a carrier structure including at least one bar and a supporting member in a normally utilization position. In the event of an accident, the supporting member leaves the utilization position and assumes a crash position, in which the supporting member is located in front of the utilization position at least in the x-direction. An expandable container is disposed between the bar and the supporting member in a normally non-expanded state. A source of pressurized gas is connected to the container. A trigger device releases the gas in the event of an accident so that the expandable container is filled with gas and is in an expanded state so that the supporting member is in the crash position.

Abstract: The headrest has a first structural component for fastening the headrest to a seat back of a motor vehicle seat and a second structural component that is movable with respect to said first structural component in the event of a crash. A drive unit is disposed between the first structural component and the second structural component and comprises a locking unit, which is locked in the normal case, and a crash sensor connected to the locking unit which it controls. The locking unit comprises a disengagement drive with an electromagnet or a piezoelectric drive. The locking unit has one retainer member associated with the first structural component and one movable disengagement member associated with the second structural component. Retainer member and disengagement member are connected together via a hinge or via balls. The disengagement drive is capable of causing said disengagement member to move.

Abstract: The headrest of an automotive vehicle seat has at least one bar (20) and one supporting member (26). Normally, the supporting member (26) is in a utilization position. When the automotive vehicle is involved in an accident, the supporting member (26) leaves the utilization position and adopts an accident position in which it is located in front of the utilization position. The at least one bar (20) comprises an oblique portion (30) that is located above an upper edge (32) of a backrest of the automotive vehicle seat. Said oblique portion has one component in the x direction and one component in the z direction. The supporting member (26) comprises a guide region (34) that conforms to the oblique portion (30) of bar (20) and that is movable relative to the oblique portion (30). An elastic means (spring 48) biases the supporting member (26) in the accident position. A releasable locking device (52) is associated with the elastic means, which it normally blocks.

Abstract: The invention relates to forming equipment for rolling and profiling disk-shaped and ring-shaped parts of a metallic material, e.g., of steel, of super alloys, aluminum alloys, etc., whereby a pressure rolling device without its own axial drive designed as a transportable and replaceable construction unit that it can be replaceably mounted in a conventional forging press between a press ram and the press bed plate for axial rolling. Because of this, the investment costs for otherwise conventional pressure rolling machines is reduced considerably and current forging presses can be used without remodeling for axial rolling by integrating a pressure rolling device according to the invention.
