  • Patent number: 8544886
    Abstract: The invention relates to a steering system for a motor vehicle with electrical power assistance comprising: a steering-spindle bearing unit, in which the steering shaft is mounted rotatably and is guided in a slide, which can be connected to the vehicle body, wherein the steering-spindle bearing unit is adjustable at least in its inclination, an electric motor, which is coupled rotatably via reduction gearing to a steering spindle, wherein the reduction gearing is enclosed and mounted in a housing, wherein the housing has means for forming a swivelling axis, about which the steering-spindle bearing unit is adjustable in its inclination, wherein the steering system further comprises a retaining clamp for fastening the steering system to the motor vehicle, wherein the retaining clamp has a guideway that interacts with a counterstay arranged on the slide, wherein the slide is movable along the guideway after it overcomes a presettable releasing force, and in the case of displacement of the slide along the guidew

  • Publication number: 20100131009
    Abstract: A spinous process implant, and a method therefor can be positioned with its longitudinal axis substantially perpendicular to the median sagittal plane of the patient, between an upper and an adjacent lower spinous process. The implant comprises, as spacers, upper support means, and lower support means, which, in each case, are applied with a recess saddle against the upper or lower spinous process. The support means can be spread apart in each case by means of clamping means, which are arranged between the support means in the longitudinal direction.
