The object of the invention 'is diagram matically represented in the drawings,`the elast-ic devices being composed of springs. Fig. 1 represents a cross view of the protective device, Fig. 2 permits a view in perspective of the device when in use and Fig. 3 represents a view of the device itself.

Underneath a :Erame l eonsisting of material of greatest elasticity a co-rrespondingly bentflat spring 2 has been provided which is connected with a spiral spring 3.

This spiral spring is shaped in such a mane ner and the coils are arranged in a way that one coil fits `Ento the, next lower one when the spring is pressed together. This spring 3 is fitted at its lower free end with a bottom plate 4:. The frame 1 is furthermore connected with a spiral spring 5 which is gradually tapering towards the bottom plate and forms a support for a cover 6 preferably consisting of leather, iinen, wire net-!sings or the like surrounding the whole device.

The fiat spring 2 on that side turned towards the franie 1 is equipped with an attachment 7 of elastic material, as for instance rubber or the like. this cap for-med by the frame 1 and'the spring 2 is also lined with a protective 'cver 8, made of leather, etc., and between he external cover 6 and the internal cover 5 a stufling has been provided co-nsisting of liorsehair seaweed 'or the like.
