Abstract: Traditional cuffs for measuring blood pressure use an air chamber enclosed in a non-stretchable fabric to occlude an artery in a limb when supplied with pressurised air. A stethoscope used on the limb is used to monitor blood flow. Application of the cuff is inconvenient and correct placement of the stethoscope chestpiece requires skill. According to the invention blood pressure measurement is facilitated by having the air chamber enclosed in a pre-formed shell-like structure being flexible around the limb and stiff along the limb and by using a linear array of microphones to detect the blood flow noises, the best signal from one of the microphones being automatically selected. Furthermore, the invention provides a facility for correcting the reading in dependence of the amount of wrap of the limb.

Abstract: A process for foaming around a peripheral edge area of a cover (10) for a motor vehicle roof, the cover being placed on or in a foaming tool and the foam mass (18) being fed into the foaming tool such that two foam mass fronts are formed which run around the peripheral edge in the peripheral direction and merge with one another or meet one another in the merging area at a side opposite that at which the foam was introduced. The foaming tool is made such that, in the merging area, the cross section of the foam mass is reduced on the side opposite the ventilation side (40) of the foaming tool that is vented relative to the areas (42, 142) which border the merging area in order to prevent inclusion of gas bubbles in the merging area. Furthermore, a cover for a motor vehicle roof is produced which has a foamed peripheral edge area in which two foam mass fronts, which are formed during the peripheral foaming in a foaming tool, merge with one another.

Abstract: A motor vehicle safety mechanism has a component which can be displaced out of a rest position suddenly into an action position by release of a holding device. Such a motor vehicle safety mechanism is, for example, a head support/roll bar which extends automatically in an accident. The holding device has a latch which fixes the component in the rest position and a ratchet arrangement which holds the latch in the action or engagement position. The ratchet arrangement has ratchet kinematics and an adjustable blocking element. By moving the latch out of the engagement position into the direction of the release position, the ratchet kinematics are moved and the blocking element blocks the movement of the ratchet kinematics.
