  • Fig. 7 is another possible and possibly independent training of a cross-sectional reduction 32 on one of the support elements, in the present case, the support member 33, shown, again for like parts the same component designations or reference numerals as in the preceding Fig. 1 to 6 be used. To avoid unnecessary repetitions will refer to the detailed description in the previous Fig. 1 to 6 referred or referred.
  • the cross-sectional reduction 32 is formed in the support elements 33 shown here by a groove 37 extending into the support element 33, wherein the groove 37 is formed by these laterally delimiting groove surfaces 38.
  • the groove or the laterally delimiting groove surfaces 38 extends in an inclined direction to the outer surface 35 of the support element 33 in this.
  • a groove bottom 39 is arranged at a distance from the outer surface 35 of the support element 33, the cross-sectional reduction 32 or the reduced cross section of the support element 33 remaining between the groove bottom 39 and this surface 35 by the remaining material or material of the support element 33.
  • cross-sectional reduction 32 in the previously different embodiments in all the support members 31, 33 may find application.
  • a multiple arrangement of cross-sectional reductions 32 is also possible in any combination and embodiments with each other.
