A radially expandable spinal interbody device for implantation between adjacent vertebrae of a spine is deliverable to an implant area in a radially collapsed state having minimum radial dimensions and once positioned is then radially expandable through and up to maximum radial dimensions. The expanded radially expandable spinal interbody device is configured to closely mimic the anatomical configuration of a vertebral face. The radially expandable spinal interbody device is formed of arced, pivoting linkages that allow transfiguration from the radially collapsed minimum radial dimensions through and up to the radially expanded maximum radial dimensions once deployed at the implant site (i.e. between adjacent vertebrae). The pivoting linkages have ends with locking features that inhibit or prevent overextension of the linkages. In one form of the locking features, one end of the linkage includes lobes that form a pocket while the other end of the linkage includes a projection that is adapted to be received in the pocket of the lobes of an adjacent linkage. A kit is also provided including a tool for the implantation and deployment of the spinal interbody device into an intervertebral space.

The subject matter of the invention is a way of shaping anatomically the safety belts of cars, particularly for the use of women, and the devices required for its realization. The essence of this anatomical shaping of a safety belt consists in providing such a form of the belt that it looks like an elongated S, passing between the breasts as well as above and under the bust. For its purpose a safety belt is provided with a shaping strip, which is a flat sleeve made of elastic plastic material in the form of an elongated S, with a rigid material lining, open on the side and closed by means of any kind of fastener, for example a zipper or Velcro.

The strip is put on the safety belt, so that it takes the required shape without affecting the structure of the safety belt. The strip can be shifted along the safety belt, adapting it to the height of the passenger. It is practically stable on the safety belt because of its shape, but it can be additionally stabilized by means of a tension pull, the length of which can be adjusted according to the needs of the wearer. The pull can be provided with a clasp, attached to the outer bottom part of the edge of the abdomen part of the safety belt, e.g. by using a clip. Due to different constitutions of the human body there are several hooks for adjusting the position. The tension pull preferably is run perpendicularly to a tangential line of the lower edge of the strip.
