ABSTRACT:
A tensioning device has a worm gear mounted in a hollow section enabling the longitudinal displacement of a lift member with respect to a hollow section. The hollow section base and the lift member in each case carry a joint bolt, which cooperates with joint heads fixed to the adjustment means. The worm gear permits a very sensitive and exact setting of the spacing between the two joint bolts, which remains unchanged over a long period. In addition, the tensioning device is particularly suitable for orthopedic purposes, due to its small constructional volume.
