 The scheme of movement of the seat and backrest according to the program: by turning the seat to a predetermined angle away from the backrest, having previously unfastened the backrest, set the backrest to different heights from the floor and back. The directions of movement of the points of the seat and back are indicated by arrows.

 The base of the support module is made with sidewalls 1 and rear upper struts 2, for example, it can be two sidewalls 1 in the form of a soft “b” sign, connected by cross members: front 3 and rear 4 (Fig. 1); or have another type of furniture preferred, for example, as shown in FIG. 6 have floor legs connected by spurs 5 and armrests 6. For a vehicle seat, a base is preferable, for example, in the form of a central support 7 of a bearing sidewall 1 connected by cross members 3 and 4, and rear upper struts 2 (Fig. 17, 18, 21) . Other structural options for the execution of the base are also possible.

 On the basis of the possibility of moving relative to it, a backrest 8 and a seat 9 are placed, which ends “a” are interconnected pivotally by a common axis 10, freely supported on the sidewalls 1. The back and seat have ends “b” free from the connection.

 The seat 9 is mounted on the base with the possibility of rotation relative to it and for this purpose from the end side “b” it is pivotally mounted directly on the front cross member 3, for example, using hinges 11 (Fig. 4) or can be rigidly connected to the rod 12, the ends of which are placed with the possibility of rotation in the sockets 13 (Fig. 15, 16). To adjust the angle of "in" the rotation of the seat 9 can be latches, rearranged in slots 15 (Fig. 2), or the lower front cross member 16, rearranged in curly grooves 17 (Fig. 15). In some particular cases of execution, the floor support of the base, for example, the central support 7 (Fig. 22), or the footrest 18 (Fig. 8, 17), with which the support module is provided for greater comfort and which can be made, can serve as a limiter of the angle of rotation of the seat " at the same time "with the seat 9 (Fig. 8).

 The backrest 8 in the initial position (vertical) is freely positioned along the uprights 2 and is provided on the back with fastening elements 19 that interact with the backing elements 20 of the uprights 2 for fixing the backrest relative to the uprights in a vertical or horizontal position. The implementation of the elements 19 and 20 provides the ability to fix the back with its placement at several different horizontal heights from the floor and can have several solutions. Thus, the elements 20 can be made in the form of several rows of crossbars arranged parallel to the axis 10 (Fig. 4), the elements 19 being hooks that “snap” onto the crossbar, or in the form of movable plates 21 mounted on the back 8 with hooks 22 at the ends which are placed with the possibility of movement in the guides 23 made on the back 8 (Fig. 14). The rear cross member can be made with the possibility of adjusting its location in height (Fig. 15). The conditional line shows the intermediate position of the OM.

 To increase the stability of the support module, for example, converted into a bed, additional retractable supports 24 are used (Fig. 3; 15).

 To facilitate the design and reduce the cost of manufacturing the rack and side walls of the base, as well as its other elements, including support 24, can be made tubular (metal or plastic). The back and seat can be made in the form of a metal or plastic sheet, or woven from synthetic or natural material.

 For greater comfort, the back and seat can be equipped with additional swivel or retractable or folding platforms 25 that increase the supporting area of the device (Fig. 8; 9; 23) and / or removable pads type 26 with soft filling, for example foam rubber, fitted if desired decorative fabric (Fig. 6; 11).

 In the initial position, the support module has the form of a chair (chair, seat for a vehicle) or sofa (bench) - the design solution for these types is identical, they differ from each other only in overall dimensions.

 Variants of compositional placement during operation of several supporting modules are possible, for example, as shown in FIG. 11 in the form of a double-sided sofa, and in this case, it is recommended to connect their bases with clamps 27.

 The essence of the method of converting the support module from one type to another, implemented by the proposed constructive solution of the device, is illustrated by a specific example of the support module, for example, in the form of a piece of furniture in the initial position of the bench and intended for use with the possibility of converting it, as necessary, into a table or a bed and vice versa by moving its back and seat relative to the fixed base by moving the back from a vertical position to horizontal and different ovnevoy fixing it by rotation of the seat by a predetermined angle "a" or "a '."

 In a specific example: the base consists of two sidewalls 1 with rear struts 2, made in the form of a soft "b" sign and connected by crossbars 3 and 4, and equipped with retractable supports 24. The seat 9 is pivotally mounted on the crossbar 3. Elements 19 are made in the form of spring hooks, and the elements 20 - in the form of bars. To adjust the angle of rotation of the seat 9 are rods, for example, in the form of a latch 14, rearranged in sockets 15 and 15 ', the placement of which is selected structurally and corresponds to the specified values of the angles "in" and "b" of the rotation of the seat (Fig. 2).

Having established the specific type of the reference module, which they want to receive as a result of the conversion, the cycle of conversion actions is carried out in the following order:
when converting to a table, the hooks 19 are removed from the crossbeam (crossbeam) 4, unfastening the backrest 8 from the uprights 2. Then, supporting the backrest 8 behind the end "b ', by pressing the end end" b "of the seat 9, turn it around the cross member 3 away from the back for a predetermined angle “c”; in this case, the backrest connected with the seat is moved from vertical to horizontal and the hooks 19 on the cross member 4 are latched, then the latch rod 14 is inserted into the hole 15, thus the back is fixed relative to the struts 2 at the level “c” from the floor provided ergonomic norms for the table top To extend the surface of the table, the sliding platform 25 is advanced along the guides from the back 8.

 Returning to the initial position (benches) is carried out by turning the seat 9 in the opposite direction to its horizontal position on the base, first removing the latch 14 from the hole 15 and fixing the back by opening the interconnection of the elements 19 and 4, translating it into a vertical position with placement along the struts 2, and again, the elements 19 and 4 are fixed relative to each other by snapping the hook 19 on the cross member 4. The retractable platform 25 is returned to its original position.

 The surface of the table can be installed in a lower position C ', for which the seat 9 is rotated at an angle "B", and the latch 14 is fixed in the hole 15' (Fig. 2 conditional lines), the hook 19 is fixed on the crossbar 20.

 When converting to a bed, unlocking the backrest 8 relative to the uprights 2 by opening the elements 19 and 4, turn the seat 9 180 degrees, while the backrest 8 will lie on the sidewalls 1. To increase the surface of the bed, extend the platform 25, fixing its hooks on the previously extended upper support 24.

 To increase the stability of the bed, the floor support 24 is extended and fixed in the extreme right position (Fig. 3).

 Thus, by turning the seat in one direction or another, the backrest is alternately moved to a horizontal or vertical position, which leads to a modification of the device, and by changing the angle of rotation of the seat, the level of the horizontal position of the backrest from the floor is adjusted, which is necessary for ergonomic and comfort reasons, in which fix it.

 In this case, the backrest - tabletop or backrest - bed has a fairly reliable support: on one side (b) it rests on the struts 2, for example, on the cross member 4 or 20, and the buttress for the other side is the end face “a” of the seat fixed in the upright position 9 that allows you to ensure the necessary balance of the design without the use of additional tools in it, thereby achieving simplification of its design and increase operational reliability.

 By multi-level horizontal placement of the backrest within the same structure, they expand the conversion range of the device, which ensures the creation of a compact multifunctional support module.

 The balance of the design allows the use of lightweight material in its manufacture, which, along with the achieved simplicity of the design and the method of conversion, facilitates the conditions for using the device.
