1. In an x-ray diagnostics installation having an x-ray source which emits x-rays and including at least one component adjustable in position, the improvement of a radiation protection arrangement for preventing x-rays from emerging from a protected area, said improvement comprising: a guide rail attached to said component;  a plurality of x-ray-impenetrable straps each having a carrier and each carrier being movably mounted in said guide rail; and  brake means for mechanically interacting with said carriers for at least impeding movement of said carriers in said guide rail when said component is adjusted in position.  a guide rail attached to said component;  at least two x-ray-impenetrable straps each having a carrier and each carrier being pivotably mounted in said guide rail, and each carrier having a formed part for diverting the strap attached to that carrier when that strap is pivoted; and  brake means for mechanically interacting with said carriers for at least impeding movement of said carriers in said guide rail when said component is adjusted in position.  a guide rail attached to said component;  at least two x-ray-impenetrable straps each having a carrier and each carrier being movably mounted in said guide rail;  brake means for mechanically interacting with said carriers for at least impeding movement of said carriers in said guide rail when said component is adjusted in position; and  means for mounting the respective carriers of said at least two x-ray-impenetrable straps relative to said x-ray source for preventing x-rays from emerging from a protected area, said means for mounting comprising means for joining said at least two x-ray-impenetrable straps to each other in a first direction and for aligning said at least two x-ray-impenetrable straps in a second direction, said first and second directions having a non-zero angle relative to each other.  a guide rail attached to said component;  a plurality of x-ray-impenetrable straps each having a carrier and each carrier being movably mounted in said guide rail;  brake means for mechanically interacting with said carriers for at least impeding movement of said carriers in said guide rail when said component is adjusted in position; and  at least one of said x-ray-impenetrable straps being comprised of foldable material, and means for fixing said at least one x-ray impenetrable strap in a folded-over position for permitting access to said protected area. 2. The improvement of claim 1 wherein all of said carriers are connected together in a chain. 3. The improvement of claim 2 wherein said brake means comprises means for engaging at one of said carriers. 4. The improvement of claim 2 wherein said brake means comprises means for engaging between two adjacent ones of said carriers. 5. The improvement of claim 2 wherein said brake mans comprises means for engaging an end of the carriers connected in a chain. 6. The improvement of claim 1 wherein said brake means comprises a friction brake. 7. The improvement of claim 6 wherein said friction brake comprises a brake lining and a resilient element which forces said brake lining into engagement with at least one carrier. 8. The improvement of claim 1 wherein said x-ray source and said component comprise an x-ray aiming device. 9. In an x-ray diagnostic installation having an x-ray source which emits x-rays and including at least one component adjustable in position, the improvement of a radiation protection arrangement for preventing x-rays from emerging from a protected area, said improvement comprising: 10. The improvement of claim 9 wherein said formed part comprises a bead. 11. The improvement of claim 10 wherein said bead is disposed at a retainer portion of the carrier. 12. The improvement of claim 10 wherein each annular strap has a swiveling axis, and wherein said bead comprises an annular bead surrounding said swiveling axis. 13. The improvement of claim 9 wherein said formed part is integrally embedded in said strap. 14. The improvement of claim 9 wherein said formed part is attached to said strap. 15. In an x-ray diagnostic installation having an x-ray source which emits x-rays and including at least one component adjustable in position, the improvement of a radiation protection arrangement for preventing x-rays from emerging from a protected area, said improvement comprising: 16. The improvement of claim 15 wherein said means for mounting comprises means for aligning said at least two x-ray-impenetrable straps substantially parallel to each other in said second direction. 17. The improvement of claim 15 wherein the respective carriers of said at least two x-ray-impenetrable straps are connected to each other in a chain. 18. The improvement of claim 15 wherein said means for mounting includes a guide rail surrounding said x-ray source. 19. In an x-ray diagnostic installation having an x-ray source which emits x-rays and including at least one component adjustable in position, the improvement of a radiation protection arrangement for preventing x-rays from emerging from a protected area, said improvement comprising: 20. The improvement of claim 19 wherein said means for fixing comprises a snap fastener. 21. The improvement of claim 19 wherein said means for fixing comprises a hook-and-loop fastener. 22. The improvement of claim 19 wherein said means for fixing comprises a clip. 23. The improvement of claim 19 wherein said means for fixing comprises a magnet connection. 24. The improvement of claim 19 wherein said means for fixing comprises means for fixing said at least one x-ray-impenetrable strap in a plurality of selectable folded-over positions.
