In an embodiment of the retainer for the pelvis and hips shown in FIG. 1, the elements of the first pair of guide elements 8 can be made in the form of a buckle with a movable jumper (for example, HSi80; http: //www.fïnsterwalder-charly.de/en/ buckles-and-strap-adjusting-units / strap-adjusting-units.html).

In an embodiment of the retainer for the pelvis and hips of FIG. 2, as well as the device depicted in FIG. 3, the elements of the first pair of guide elements 8, as well as the third pair of guide elements 10 can be made in the form of a buckle with a fixed jumper, or a rectangular buckle with one slot or hole (for example, HSi700, HSi1610; http: //www.finsterwalder-charly .de / en / buckles-and-strap-adiusting-units / strap-adjusting-units.html).

In an embodiment of the retainer for the pelvis and hips of FIG. 1, FIG. 2, as well as the device shown in FIG. 3, the elements of the second pair of guide elements 9 can be made in the form of a buckle with a movable jumper (for example, HSi80; http://www.finsterwalder-charly.de/en/buckles-and- strap-adjusting-units / strap-adiusting-units.html).

Elements of the fourth pair of guide elements 11 of the device of FIG. 3, can be made in the form of guiding belts of tubular channels, holes, rings, rollers, their assemblies, etc., fixed to the upper part of the back of the user's chair (or made in them) and providing the necessary direction and minimal friction of the belts on interacting with them elements.

Communication links making up the first pair of communication links 12 can be made with the possibility of changing their length, for example, in the form of segments of a belt of safety belts, one end of each of which is fixed to the corresponding part of the means of detachable connection (6 or 7), and the other end held by the movable jumper of the corresponding element of the first pair of guide elements 8, which are used buckles with a movable jumper (for example, HSi80; http://www.finsterwalder-charly.de/en/buckles-and-strap-adjusting-units/strap -adjusting-units.html.

Communication links making up the first pair of communication links 12 can also be made in the form of rectangular buckles (for example, HSi700, HSi1610; http://www.finsterwalder-charly.de/en/buckles-and-strap-adiusting-units/strap -adiusting-units-html or rings made from segments of the seat belt tape and equivalent elements (in the form of rectangular buckles or rings, they can be used as elements of the first pair of guide elements 8), providing strong bonds of the first part of the detachable connection 6 and second parts of detachable connection 7 with their respective ends of the third emnya 3 as well as with the corresponding elements of the first pair of guide members 8.

Communication links making up the second pair of communication links 13 can be made in the form of segments of a belt of safety belts equipped with their fastening means (for example, in the form of a triangular buckle with a slot for a belt, fixed by means of an axis on the corresponding elements of the vehicle, similar to those shown on http : //www.schroth.de/Rennsport/Zubehoer/Schrittgurt-I-Schraubbeschlag/Schrittgurt-1-Schraubbeschlag-Schwarz.html, which provide strong connections of each element of the second pair of guide elements 9 with the side parts of the seat frame of the user chair.

The lining 14 is a flexible elastic plate, the connection of which with the first belt 1 and the second belt 2 prevents the displacement of these belts along the hips towards the pelvis and provides a predetermined position of these belts relative to the hips and pelvis of the user.

As a means of tension 15, buckles with a movable jumper can be used (for example, HSi80; http://www.finsterwalder-charly.de/en/buckles-and-strap-adjusting-units/strap-adjusting-units.html), through which the first belt 1 and the second belt 2 are passed, by pulling the free ends of which by hand, for example, it is possible to reduce their length and, thus, carry out manual tensioning (embodiments of such a tensioning device are shown in Fig. 1, Fig. 2 and Fig. . 3).

Also, as a means of tensioning 15, a loop of the fourth belt 4 can be used to tighten the stretchable belts, one end of which is fastened (for example, to a spatially fixed buckle with a movable jumper or a fixed element of the vehicle), and the other end is connected to the tensioner 16, mounted on the vehicle (such a loop tension of the third belt 3 is shown in Fig. 3).

The retention device is used as follows.

When using all variants of the device (Fig. 1, Fig. 2 and Fig. 3), the second pair of guide elements 9 is fixed directly or by means of the links of the second pair of communication links 13 on the side parts of the user's seat frame.

A fourth pair of guide elements 11 is fixed to the upper part of the back of the user's chair on both sides of his neck, and the lining 14 (Fig. 1, Fig. 2, Fig. 3) is placed on the seat cushion of the user.

The belts of the shoulder-holding means intended to hold the user by the shoulders are made in the form of a single belt 3, which is passed through the guide elements 11 and the ends of which are connected with the corresponding parts of the detachable joint 6 and 7, and its middle part is covered by a fourth belt 4 connected to the fixed on the structural elements of the vehicle with a tensioner 16, which is part of the tensioning means 15, and fix the end of the fourth belt 4 on the structural elements of the vehicle (Fig. 3).

The user is placed in the chair intended for him, sitting on the lining 14 lying on the seat cushion, connected with the first belt 1 and second belt 2 (Fig. 1, Fig. 2, Fig. 3), moves along the branches of the third belt 3 to the corresponding height the height of the screed 5 and imposes on the shoulders the branches of the third belt 3, as a result of which the screed 5 is placed on the back and shoulders of the user, holding the branches of the third belt 3 at a predetermined distance between them, behind the user's neck.

After that, the user places on the hips parts of the means of holding the pelvis, and then connects the first part of the means of detachable connection 6 and the second part of the means of detachable connection 7.

Devices with retainers for the pelvis and hips shown in FIG. 1, FIG. 2 and FIG. 3, they are brought into operation by tensioning the belt formed by connecting the first belt 1 and the second belt 2 (directly, or through the lining 14), manually, applying a pulling force to the free ends of these belts (indicated by an arrow extending from the end of the belt) emerging from buckles with a movable jumper used as the second pair of guide elements 9. The shoulder branches of the third belt 3 are then pulled by a tension means 16 made, for example, as shown in FIG. 3.

Since the hip belt of the pelvic restraint is held on the user's hips by tensioning parts of the first belt 1 and second belt 2, covering the user's hips from below and from the sides (limited by the guiding elements of the first pair of guiding elements 8 in the case of the means shown in Fig. 1; or guides elements of the third pair of guide elements 10, in the case of the means depicted in Fig. 2 and Fig. 3), to increase the holding forces (i.e., the vertical components of the tension forces of these belts) it is necessary to Place the indicated guiding elements (bounding loops of belts covering the hips from below and from the sides) closer to the lateral surfaces of the hips.

Therefore, to bring the device into working condition, the user (after the steps described above), if necessary, additionally verifies the position on the hips of the guide elements or by acting on buckles with a movable jumper used as guide elements of the first pair of guide elements 8 of the means shown in FIG. . 1, and thus changing the length of the links of the first pair of communication links 12; or by moving by hand along the first belt 1 and second belt 2 the elements of the third pair of guide elements 10 (in the form of buckles with a fixed jumper, or rectangular buckles with one slot or hole) of the means depicted in FIG. 2, and the device depicted in FIG. 3.

The achievement of the technical result, which consists in ensuring reliable retention of users significantly different in height, is achieved by moving the tie 5 along the branches of the third belt 3 to the height corresponding to the user's height, as well as by changing within a wide range the size of the loop covering the user's hips from below and from the sides, by changing tension of the first belt 1 and second belt 2 by acting on buckles with a movable jumper used as elements of a second pair of guide elements 9 (Fig. 2, Fig. 3), whether, if necessary, an additional change in length of the links of the first pair of links connection 12 impacts on their belts and buckle with a movable crosspiece applied as guide elements of the first pair of guide members 8, based on the holding means device for the pelvis and thighs of FIG. one.

An increase in the retention forces of the retaining means for the pelvis on the user's hips from its possible displacement up is achieved by moving the guiding elements limiting the belt loop covering the hips from below and from the sides, closer to the lateral surfaces of the hips in accordance with the growth of the user, or by changing the length of the links of the first pair communication links 12; or by manually moving along the first belt 1 and second belt 2 the elements of the third pair of guide elements 10.

When braking occurs, the screed 5 holds the branches of the belt 3 on the shoulders of the user directly behind his neck, ensuring his reliable retention by the shoulders.

Under the action of the load from the user's holding body, the elements of the first pair of guide elements 8 are moved forward and down along the belt formed by the connection of the first belt 1 and the second belt 2 (Fig. 1, Fig. 2, Fig. 3), and the holding means for the pelvis is shifted forward - down and pressed to the hips by the forces of tension of the indicated belts. As it brakes, the upper body of the user, held by the branches of the third belt 3, moves forward, and the user's pelvis approaches a vertical position. The combination of the means of holding the pelvis and pelvis of the user in the upright position pressed to the hips ensures reliable holding of the user by the pelvis and hips with the exception of “diving”.
