Abstract: In an apparatus for producing foamed plastics parts, a closed mold (1) is filled with polymer molding compound and, after the elapse of a reaction time, the finished part is removed. A plurality of identical molds (1) run on mold carriers (5) through a production installation. For the purpose of reducing the production outlay, a demolding device (11) shared by all the molds (1) is brought into operative connection successively with the molds (1) and in each case one mold (1) is opened. The movements required in this operation are executed by the demolding device (11). An unlocking unit (19) and a swiveling unit (20) of the demolding device (11) are brought into engagement with the mold (1) by a positioning unit (21), after which the mold (1) is unlocked and one mold half (1a) of the mold (1) is swung open. For unlocking the mold (1), the latter is raised against spring force and a positive locking is brought out of engagement.

Abstract: Erecting mechanism for a swivel-up rollover bar for vehicles, in particular for four-seat convertibles, having a bar leg which is supported in a swivel bearing on one vehicle side and which can be swivelled about a transverse axis of the vehicle and has a supporting section which is remote from the swivelling axis and serves to support the vehicle during a rollover movement the supporting section of the bar leg is swivelled up on a curved path which extends, at least over a partial swivelling angle, around the swivel bearing on a path different from a circular arc by virtue of the fact that the useful length of the bar leg varies with the stroke.

Abstract: A wind guard is disclosed for a convertible which is arranged behind a row of seats, extends up beyond this row of seats and runs over the entire width of the interior space and which is formed by a stretched, elastically deformable net which effects a retardation of the air flow appearing from the rear. To further develop a net used here, with regard to an optimum influence on the air flow appearing from the rear, the portion of the clear passage openings to the total net area is about 30 to 35%, the individual passage openings are defined all round by webs extending approximately at right angles to one another and having a round to oval cross-sectional shape, and the wall thickness of the webs is about 0.15 to 0.3 mm.

Abstract: The application relates to a convertible automobile with a windscreen which is arranged behind a row of seats and which extends vertically upwards and beyond the top of the seats and which extends for the entire interior width of the vehicle. In order to develop a windscreen of this type in such a way that annoying draft phenomena are prevented while the typical "convertible feel" is maintained, the windscreen is formed by a stretched elastically deformable net which causes a deceleration of the air flow impinging from the rear of the vehicle towards the front.

Abstract: The application relates to a windscreen for a convertible with an approximately U-shaped roll bar pivotable about a transverse axis of the vehicle into an approximately horizontal position of rest. The windscreen has a first part pivotable upwards behind a front seat row and a second part horizontally covering the space behind the seat row approximately level with the belt line of the vehicle. The two windscreen parts are connected pivotably to one another with the first part resting on the second part in its position of rest. In order to ensure especially simple actuation the roll bar, movable by means of a convenient drive mechanism, is utilized to shift the first part of the windscreen into its directed operating position.

Abstract: A convertible motor vehicle is provided with a wind-deflecting cover which covers the space behind a front row of seats at the top. A windscreen is secured on the cover and, in the operative position, projects approximately vertically from the level of the upper edge and can be lowered into an out-of-use position. The windscreen is formed by a roller blind having a winding-up roller fixed at a forward boundary edge of the cover. An alternative arrangement for accommodating a windscreen on the cover in the out-of-use position forms a single unit with the cover which has two panels resting one upon the other and arranged to be swivelled open at a hinge. Opposite to this hinge, the windscreen is swivellably fixed at a forward boundary edge of the lower panel and can be swiveled in between these panels.

Abstract: An axially adjustable steering device for motor vehicles comprises two jacket-tube parts, of which the inner jacket-tube part is displaceable telescopically in the outer jacket-tube part by means of a controllable drive, a worm gear received in a reception part pivotably mounted fixedly relative to the vehicle acting on an axial tooth-profile part on the inner jacket-tube part in a longitudinally displacing manner. The reception part is retained via a locking mechanism in an engagement position of the worm gear and tooth-profile part, and this locking mechanism is releasable in a controlled manner during a front collision, after which the worm gear is pivoted out of engagement with the tooth-profile part and the inner jacket-tube part is moveable into a position shifted furthest in the forward direction.

Abstract: A piston-cylinder unit, which erects a swingable roll bar in a crash situation by an ejection spring, includes a controllable drive by which the movement and the direction of movement of the piston can be controlled and which can be disengaged in the event of a crash pulse, whereupon the piston extends rapidly by virtue of the ejection spring.

Abstract: The invention relates to bracing of vehicle body structures that are deformed with absorption of energy upon collision wherein a resiliently front mounted engine of a motor vehicle has connected thereto a longitudinally extending tension band fastened to the vehicle body structure laterally adjacent to the engine which tension band is extended upon collision and wherein the bracing function of the front engine is largely independent of the course of deformation of the car front in the case of a frontal collision, and wherein the tension band is constructed as a flexible traction cable at least along a part of its length and wherein along its length it is provided with a stress absorbing means for the absorption of forces after an intended partial deformation of the vehicle body structure associated with it.

Abstract: To economize weight, an arcuate support tube of a roll-over yoke is produced from high-tensile heat-treated material and received by both members and by part of the adjacent median region in bracing structures which mount it on the motor car body and which consist respectively of two mutually connected half-shells which positively enclose and thereby retain the support tube.

Abstract: A device for actuating a safety device, in particular a roll bar in a motor vehicle.

The device also includes second and third sensors which control switches when both at least one wheel suspension is fully extended and the vehicle is tilted about either a longitudinal or transverse axis, so as to actuate the safety device during even relatively slow overturns.

Abstract: In order to prepare thermoplastic polyurethane elastomers(a) organic diisocyanate,(b) polyhydroxyl compounds with molecular weights of 500 to 8,000, and(c) chain extenders with molecular weights of 60 to 400 in the presence of(d) catalysts, and optionally(e) auxiliaries, and/or(f) additivesare reacted in two reaction stages at temperatures from 60.degree. C. to 250.degree. C. In the first reaction stage the components are continuously mixed, the reaction mixture is applied to a carrier, preferably a conveyor band of thermoplastic material, and is allowed to react at the reaction temperature until solidified. Subsequently, the solidified reaction mixture is melted in an extruder and the reaction is completed in the second reaction stage.

Abstract: To prevent the possibility of the upper extremities of a strapped-in passenger in a convertible vehicle from going beyond the extension of the tiltable roll bar in the event that the vehicle turns over, despite the fact that the roll bar is erected, the latter is extended beyond its particular pivoting point, and this extension engages around the shoulder-belt part between its deflection point and the lower fastening point, and when the roll bar is swung up, causes a tautening of the belt-band run because the shoulder-belt part is taken up.

Abstract: Method of treating synthetic threads, particularly filament or foil threads comprises heating the threads up to the center of their cross-section, crimping the heated thread, forming the crimped threads into a wadding, heating and compressing the wadding to reduce its volume and thereafter cooling the compressed wadding. An apparatus for treating the yarn includes a continuous heating chamber which is arranged adjacent a cooling chamber. An apparatus is provided for feeding the yarn to be treated toward the heating chamber and for crimping the yarn preferably while it is heated and perhaps also stretched. Crimping may be carried on by directing the thread under a fluid force against a screen, by passing the thread between a pair of rollers which have crimping means or by a combination of the two and, in addition, stretching means may be provided to stretch the thread.
