摘要:
The present invention relates to a process for preparing sulfuric diamides of the general formula I R1R2N—S(O)2—NH2 (I) in which R1 and R2 are each independently a primary alkyl radical having from 1 to 8 carbon atoms, a secondary alkyl radical having from 3 to 8 carbon atoms or a cycloalkyl radical having from 5 to 8 carbon atoms, or, together with the nitrogen atom, form a 5- to 8-membered, saturated nitrogen heterocycle which, as well as the nitrogen atom, may have a further heteroatom selected from O and S as a ring member, where the nitrogen heterocycle is unsubstituted or may have 1, 2, 3 or 4 alkyl groups having in each case from 1 to 4 carbon atoms as substituents. The process comprises the following steps: i) the reaction of a secondary amine of the formula II R1R2NH (II) in which R1 and R2 are each as defined above with sulfuryl chloride in an inert solvent, especially an aromatic solvent, in the presence of a tertiary amine to give a sulfamoyl chloride of the formula III R1R2N—S(O)2—Cl (III) in which R1 and R2 are each as defined above, and ii) reaction of the sulfamoyl chloride of the formula III obtained in step i) with ammonia, the sulfamoyl chloride of the formula III being used in step ii) in the form of the solution obtained in step i) in the inert solvent, especially the aromatic solvent.

A tensioning device (10) for a seat belt, in particular in a motor vehicle, having a gas generator (17) and a piston (21) guided in a tube (16) that closes a pressure space (20) in the tube (16), whereas the pressure space (20) can be pressurized by the gas generator (17), as a result of which the piston (21) can be driven to perform a tensioning operation which can be transmitted to the seat belt by means of the force transmission means. The piston (21) having a closed or constricted opening (1, 1a), and the opening (1, 1a) can be enlarged and/or opened by the material erosion caused by the pressure and/or pressure conditions in the pressure space (20).

A viscous clutch (30; 30′) includes a stationary journal bracket (32; 32′) defining a mounting shaft (32-1; 32-1′), an output member (34; 34′) rotatably supported on the mounting shaft about an axis (A), an input member (34; 34′) rotatably supported on the mounting shaft about the axis, and a working chamber (50; 50′) defined between the input member and the output member to selectively transmit torque there between when a shear fluid is present. The mounting shaft extends axially through the viscous clutch from a front face (62; 62′) of the viscous clutch to a rear face (56; 56′) of the viscous clutch, with the rear face defining a mounting surface for mounting the viscous clutch at a mounting location. The front and rear faces are located at opposite sides of the viscous clutch and face in opposite directions.
