    摘要: A belt buckle assembly, especially for a seat belt system in a motor vehicle, includes a belt buckle (10) and a plug-in tongue (12) lockable in the belt buckle (10) by means of a locking mechanism. A component of the locking mechanism of the belt buckle (10) interacting with the plug-in tongue (12) inside the belt buckle (10) and/or the plug-in tongue (12) has/have design features at a locking portion (16) interacting with the locking mechanism of the belt buckle (10) inside the belt buckle (10). The design features enable the plug-in tongue (12) to be locked in the belt buckle (10) only at one of at least two possible orientations of the plug-in tongue (12) in the belt buckle (10).

    摘要: A locking tongue has a base part, a webbing slot in the base part and a locking cam. The locking cam is movable between a rest position and a clamping position. A biasing means biases the locking cam towards the rest position. The locking cam can assume the rest position in which the belt webbing can pass freely through the webbing slot, a clamping position in which the locking cam presses the belt webbing against the clamping edge of the webbing slot, the biasing means being able to return the locking cam from the clamping position into the rest position, and a locking position in which the locking cam locks the belt webbing in the webbing slot, the biasing means not being able to return the locking cam from the locking position towards the rest position.

    摘要: A system and method for incrementally maintaining column cardinality estimates in database management systems. In one embodiment, the system includes system catalog table containing a cardinality estimate for a column that is extended to include an appropriate data structure. A modified linear counting technique is used in a first embodiment of a method for column cardinality estimation. The cardinality estimate is produced by an initial scan of the data but is then further maintained without requiring a full scan of the data. Data changes are reflected incrementally in modifications to the initial cardinality estimate, keeping the cardinality statistics more current with respect to the database condition. The technique of the invention typically provides a capability for a database management system to produce more efficient search plans providing more effective responses to user queries through the use of improved cardinality statistics.

    摘要: Reinforced polyurethane/urea elastomers with a specified proportion of urea groups and a specified proportion of urethane groups are produced from an isocyanate-reactive component satisfying specified compositional requirements and an isocyanate-terminated prepolymer produced from specified materials. Two-dimensional polyurethane molded articles produced from these reinforced elastomers are characterized by improved toughness and improved shrinkage characteristics. Such molded articles are particularly useful for making automobile components.
