Abstract: The present application discloses a quick-action coupling (100) for a rotary surgical tool having a rotary shaft (20), in the distal end surface of which there is formed a tool receptacle (24) which is adapted to receive a rotary surgical tool for conjoint rotation. The rotary shaft (20) has, in the region of its distal end (21), at least one radial protrusion (22) and at least one radial aperture, wherein a locking body is arranged in the at least one aperture, said locking body being movable in the radial direction with respect to the rotary shaft (20). A sleeve (10), the proximal end of which is pushable over the distal end (21) of the rotary shaft (20), is additionally provided in the quick-action coupling.

Abstract: A rear floor structure for a motor vehicle includes, but is not limited to two longitudinal girders extending between rear wheel houses. A downwardly open pocket for receiving a shock absorber is formed in each of the longitudinal girders.

Abstract: A body structure of a motor vehicle is provided that includes, but is not limited to a floor panel, that has an inner side directed toward the motor vehicle interior and an outer side directed toward the motor vehicle exterior, and also includes, but is not limited to a seat mounting for securing a motor vehicle seat. To reduce driving noise and air resistance, it is provided that on the outer side thereof, the floor panel is free from corrugations or stiffening structures running predominantly in the transverse direction of the motor vehicle. A motor vehicle is also provided having a corresponding body structure and a method is provided for the manufacture thereof.
