A steering wheel unit for a motor vehicle. The steering wheel unit has a steering wheel and an airbag module (30) located in the hub area of the steering wheel. This airbag module forms a housing (32), an airbag (52) folded into the housing, and a gas generator (54). The airbag module can be pushed down against the force of at least one spring element to activate a horn, whereby positioning means are present which define the position of the airbag module in relation to the steering wheel. In order to achieve a high degree of operational reliability and a very exact positioning of the airbag module in the steering wheel, at least one retaining means (28;38,68) is present which acts between the airbag module and the steering wheel (28;38,68). This retaining means is ineffective in the absence of outer forces and when the airbag module (30) is pressed down to activate a horn.

Disclosed are embodiments of an airbag cushion and related airbag modules including a plurality of flaps that may be used to secure the airbag within a module housing. In one embodiment of the invention, first and second flaps are connected with the airbag cushion. The airbag cushion is adapted to be condensed into a compact configuration wherein the first flap extends adjacent to the second flap and in at least approximately the opposite direction as the second flap.
摘要:
A side dam block disposed along the widthwise end portion of a block mold is supported by springs such that the side dam block is pressed against the casting flat surface of the opposing block mold so that gap between the opposing block molds can be suitably adjusted.

A dummy nozzle is used for alignment of a pouring nozzle upon insertion of the pouring nozzle in communication with a tundish into a mold cavity of an endless track type moving-block mold continuous casting machine.
摘要:
In a block type moving mold continuous casting machine of the type wherein a pair of block molds group each consisting of a plurality of block molds interconnected with each other in the form of an endless track are disposed in opposed relationship to define a mold cavity therebetween; and molten metal is supplied from one open end of the mold cavity and a solidified casting is continuously withdrawn out of the other open end of said mold cavity, a method and installation capable of removing a block mold which has been thermally deformed during the casting process from a carrier in a simple manner and quickly replacing with a new or repaired block mold.
摘要:
In an endless track type continuous casting installation of the type in which a mold cavity having variable thickness for a casting is defined by the combination of block molds each of which is of an L-shaped cross section and which are connected with each other in the form of a loop, thereby providing each of a pair of endless tracks, safety is ensured with the block molds of the pair of endless tracks are combined to define a mold cavity.
摘要:
Disclosed is a process and apparatus for multi-strand continuous casting wherein a plurality of strands may be spaced apart from each other by a distance only dependent upon the dimensions of a copper plate and water-cooling jacket of a mold because a multi-strand mold oscillation mechanism may be installed independently of the spacing between the adjacent strands and the amplitude of oscillation of each mold may be suitably adjusted depending upon the casting conditions but independently of each other. Cast products emerging from the molds are withdrawn through a multi-strand roll apron or bending unit, a multi-strand casting bow, a multi-strand straightener and a multi-strand table by a multi-strand-pinch-roll stand consisting of a plurality of coaxial multi-pinch-roller assemblies, the individual pinch rollers in each assembly being driven independently of each other.
