Each link of the chain/frame has pintles 52 of the internal mattress frame that engage in slots 53 of plaques 54 connected to one another through joints 55. The plaques 54 can therefore be moved with respect to the links of the chain/frame and their joints 55 may be brought to coincide with the articulations 51 of the links of the chain/frame. By moving the plaques 54 the articulations 51 and joints 55 no longer coincide and the plaques 54 make the chain/frame 50 stiff. The mobility of the chain/frame is shown in FIG. 28.

(66) FIG. 29 shows a possibility to move the plaques 54 through connecting rods 56 articulated eccentrically to a disc/ring nut 57 and to the plaques 54. Therefore, by turning the disc 57 through a screw 58 that is activated by extracting or reinserting the pin into the frame, the chain/frame may be brought from a stiff position to a mobile position.

(67) In FIG. 30 the movement of the plaques 54 may be obtained by means of a Bowden cable of the known type.

(68) FIGS. 31 and 32 show the possibility of transmitting the movement from a chain/frame to the one parallel thereto through two levers sliding in respectively a slot at one end and articulated respectively to another lever at their other ends.

(77) The beam 89 is equipped at its ends with tabs 91 and 92 respectively. The two tabs 91 and 92 are respectively bendable from a position in the extension of the beam 89 into a perpendicular position to the axis of the beam 89 so as to completely, as shown in FIG. 43, or partially, as shown in FIG. 42, intercept the frame 70. This bending movement may be performed for example by means of an electromagnetic system of the known type, not shown. With the interception of the frame 70, it may be brought by the tabs 91 and 92 or only by one of the two into a raised or tilted position, in the case in which only one of the two tabs is bent. The various positions are defined with the extraction of sections 96 and 97 of the feet 68.

(78) The beam 89 also carries, in its halfway plane, a pulley 93 of the type as shown in FIGS. 16 to 18. A wire or rope 94 is wound around the pulley 93 fixed at its free end to a connection 96 integral to the support plate/sub-frame 73.
