Abstract: In a vehicle with bumper which is attached to the vehicle transverse to the longitudinal direction of the vehicle via a deformation element (10) the deformation element (10) exhibits two first side walls (28, 30) that are spaced apart, and are joined to second side walls (40, 42) that are spaced apart.

Abstract: A vehicle features a bumper which runs transverse to the longitudinal direction of the vehicle and which is attached to the vehicle by at least one deforming element. The deforming element is essentially in the form of a tube-shaped length of section of light weight metal having its longitudinal axis lying in the longitudinal direction of the vehicle and is divided into longitudinal chambers by inner struts.

Abstract: A bumper for vehicles, in particular for private cars, features an extruded section of light metal alloy that can be attached to the vehicle and exhibits in the form of section walls (12, 14) a compression wall (12) and a tension wall (14) that are spaced a distance (1) apart and a pair of transverse walls (16,18) that join these to form a hollow section, where at least one transverse strut (20, 22, 24) is provided between the transverse walls (16,18), joins these walls (12, 14) to each other and divides the hollow section into chambers. A vertical strut (26) is provided between the section walls (12, 14) joining the both transverse walls (16, 18) to each other and dividing the hollow section into a primary deformation part (A) with the chambers (30) bordering onto the compression wall (12) and a secondary deformation part (B) with chambers (32) bordering onto the tension wall (14).

Abstract: A bumper with brackets attached for mounting it onto a vehicle, in particular a private car, is such that, at least in the region of the brackets, the bumper is bowed with respect to the front line of the vehicle, and features section walls a distance apart in the form of a compression wall and a tension wall and a pair of transverse walls joining them making up a hollow section. The brackets feature a wedge-shaped support, the sloping face of which lies against the tension wall and is connected to this in region at the highest point of the sloping face.

Abstract: Play-free longitudinal guiding means having rails than run inside each other, namely a lower rail and an upper rail that can be displaced in a sliding manner with respect to the lower rail, for securing seats in vehicles such as private cars. The play-free longitudinal guiding means is such that the lower rail features along its length wall parts that have the shape of alignment grooves, and the upper rail features wall parts which run parallel to the wall parts of the lower rail and are shaped into an alignment groove, and the alignment grooves of the upper and lower rails face each other and form a sliding alignment channel. In the sliding channel there are sliding elements which in the free-standing condition exhibit a larger cross-section than in the installed condition, and the sliding elements guide the lower and upper rails without any play.

Abstract: The impact girder extruded in a light metal alloy and extending in the vehicle door approximately in the direction of travel can be fixed at both ends in such a way that a profile wall of the impact girder faces towards the inside of the vehicle as the inner flange and a second profile wall of the impact girder provided at a distance from the first forms an outer flange. Fastened to the impact girder is a hollow chamber profile, similarly extruded from a light metal alloy, with at least two profile chambers, the hollow chamber profile protruding into the door box below the impact girder and the profile chambers extending parallel to the latter. The hollow chamber profile provides additional impact protection.

Abstract: The support tube for kneepads serves to promote the passive safety of occupants in a vehicle. The support tube of non-buckling construction consists of an integrally extruded tubular piece for the absorption of force. It has no doublings, is of round, oval or rounded-off construction and has at least one internal longitudinal web. The longitudinal web/webs of a support tube preferably mounted with a screw or plug-in connection in a passenger vehicle runs/run expediently approximately in the direction of the force effect to be expected.

Abstract: There is provided a process for recovering oil from oil bearing formations employing the use of a water treating medium, which medium comprises the inclusion of a novel stable emulsion copolymer of acrylamide and ammonium acrylate as well as the emulsion copolymer per se.

Abstract: A device for supporting a moveable seat, for example a seat in a motor vehicle, by means of sliding rails which can be displaced in their longitudinal direction on roller facilities situated between the sliding rails and stationary alignment rails, the position of the seat being set by a mechanism which arrests the movement of the seat and involves, if desired, notches on at least one alignment rail, made such that it can withstand excessive loading, at the same time being simple and inexpensive to manufacture and install. This is achieved by having both the sliding rail and the related alignment rail feature at least one flange projecting out at the side, such that the flange on the sliding rail lies a short distance below the flange on the alignment rail resulting in flanges coming into contact under overload conditions. The facing flanges feature surface projections which interlock when under load.
