During the movement of the adjusting rod 34, the connecting rod 40 brings the back compartment 38 into the maximum tilt position shown in FIG.

The pin 45, which is keyed to the upper trip portion of the trapezoidal arc 42, has been moved to the other stroke limiting end of the ridge slot 61 in the rectangular arc 60.

The pin 65 of the elbow arch 63 is a trapezoidal arch 4.
Moved to the other stroke-limiting end of the two arcuate slots 44, the position of the elbow arch 63 and the inclination of the neck compartment 27 relative to the back compartment remain unchanged.

The lumbar compartment 29 and the sacral compartment 30 have been moved further downward so that the position of the connecting arm 62 to which the lumbar compartment 29 is pivotally connected remains substantially unchanged.

The thigh section 31 further swings around the pin of the upright body 67 until it finally reaches its maximum tilt position shown in FIG.

Said rocking of the thigh compartment 31 is brought about by the rotation of the conical arm 48, which at this point is further guided by the respective guide and stop slots 39.
The adjusting rod 34 reaching the other stroke-restricting end inside
Triggered by the rear pin 37. Rotation of the conical arm 48 causes the pivot pin 69 of the connecting arm 68 to move to the other travel-limiting end of the flexure slot 47 in the triangular arcuate body 43.

The leg and foot compartments 32 rotate around the pins of the upright body 72 following the swing of the edge of the thigh compartment 31 which is pivotally connected, and finally their maximum inclination. The position is reached (Figs. 4 and 12).

The pins of the uprights 72 are located in the plate 70 at the other travel-limiting end of the longitudinal slots 71.

From the flexed seated position shown in FIG. 4, the user can return each compartment of the bed 20 to any of the other rest positions described above.

After manipulating the lever 58 to disengage the pawl 50 from the fourth recess of the adjustment rod 34, the user applies an appropriate thrust to the neck compartment 27, back compartment 28 and waist compartment 29. Then, the bed 20 is rotated in the head direction. The connecting rod 40 overcomes the resistance of the tension spring 35 and moves the adjusting rod 34 towards the foot of the bed 20.

The pins 45 and 65 slide in the ridge slots 61 of the rectangular arcuate body 60 and the arcuate slots 44 of the trapezoidal arcuate body 42, respectively, to define the neck, back and waist compartments 27, 28 and 29, respectively. Guide the rotation of.

The rear cross pin 37 of the adjusting rod 34 provides for rotation of the conical arm 48 and movement of the pin 69 within the flex slot 47 of the triangular arcuate body 43.
