Description

The technical field to which the utility model relates.

The utility model relates to vehicle seats, namely to vehicle seats, including shoulder belts, waist belts, a means of holding the waist belt from lifting when impacting, and a lock for fixing the shoulder and waist belts to each other, and can be used in automobile, aviation and military industry to protect vehicle users and drivers of military equipment from inertial shock loads.

State of the art

The vehicle seat is known from the prior art, including shoulder belts, waist belts, means for holding the waist belt from being raised when impacted, and a lock for fixing the shoulder and waist belts to each other, see the description of the patent of the Russian Federation for invention No. 2265556, published on December 10, 2005 .

This device is the closest in technical essence and the achieved technical result to the proposed solution and is taken as a prototype of the proposed utility model.

Its disadvantage is the inconvenience of placing passengers and drivers (pilots) of vehicles in such a chair. This is due to the fact that, being in outerwear, especially in winter, and also in professional equipment, it is inconvenient to deliver shoulder straps and fasten them, providing the necessary fixation of all belts. If not even one of the harness belts is fastened, human safety cannot be ensured. Thus, a real utility model solves the problem of inconvenient use of the chair and safety.

Utility Model Disclosure

The present utility model, based on this original observation, mainly aims to offer a vehicle seat, including shoulder belts, waist belts, a means of holding the waist belt from lifting when impacting, and a lock to fix the shoulder and waist belts to each other, allowing at least , smooth out at least one of the above disadvantages, namely, to provide increased convenience for placing the vehicle user on the seat, fastening it with belts and safety.

 To achieve this goal, the chair contains additional belts for lifting the shoulder belts up and to the sides, connected at one end with the shoulder belts, and at the other ends with a means of tensioning the additional belts for lifting the shoulder belts.

Thanks to this advantageous characteristic, it is possible to easily lift the shoulder straps when folding the seat to form free space for an unhindered fit in the chair, as well as easy placement of the user in the chair and fixing it with straps.

There is a variant of the utility model in which the means of tensioning the additional belts for lifting the shoulder belts is made in the form of a loop located in front of the swivel seat of the aircraft seat, made with the possibility of moving and fixing relative to the swivel seat.

Thanks to this advantageous characteristic, it becomes possible to adjust the tension of the additional belts for lifting the shoulder belts.

The set of essential features of the proposed utility model is not known from the prior art for devices of similar purpose, which allows us to conclude that the criterion of "novelty" for the utility model.

Brief Description of the Drawings

Other distinguishing features and advantages of the utility model clearly follow from the description below for illustration and not being restrictive, with reference to the accompanying drawings, in which:

- figure 1 schematically depicts a front view of a vehicle seat, according to a utility model;

- figure 2 schematically depicts a side view of a vehicle seat, according to a utility model;

- figure 3 schematically depicts a side view of a vehicle seat, according to a utility model;

- figure 4 schematically depicts a front view of the seat of a vehicle seat, according to a utility model;

- figure 5 schematically depicts a handle for fixing additional belts, according to a utility model.

According to FIG. 1-5, the vehicle seat includes a backrest 11, a swivel seat 12 and a headrest 13, and

- shoulder straps 2,

- lap belts 3,

- means 31 for holding the waist belt from lifting under shock and

- lock 4 fixation of the shoulder and waist belts with each other,

- additional belts 5 for lifting the shoulder belts up and to the sides, connected at one end with the shoulder belts 2, and at the other ends with a means of tensioning the additional belts for lifting the shoulder belts.

The means of tensioning the additional belts for lifting the shoulder belts is made in the form of a loop 6 located in front of the swivel seat 12 of the seat of the aircraft, made with the possibility of moving and fixing relative to the swivel seat.

In the figures, numeral 7 shows the handle for fixing additional belts, numeral 8 shows a stop jumper on loop 6, and numeral 9 shows flexible tapes connecting additional belts 5 and loop 6.

Also in the drawings, the amount of displacement of the belts is indicated as ΔL.

Utility Model Implementation

The vehicle seat is used as follows.

1. Using the seat lift

After unfastening the lock 4 and exiting the chair, the user lifts (rotates) the seat 12. In this case, the loop 6 on the front edge of the seat 12 rests with its jumper 8 on the seat 12 and pulls the flexible tapes 9 connected to the additional belts 5. Additional belts 5 flow through the windows in the upper part of the frame at the level of the head, on the sides of it, and raise and scatter to the sides of the main shoulder straps 2.

Before the subsequent landing in the chair, the seat 12 is lowered (turned to the bottom). At the same time, flexible tapes 9 connected to additional shoulder belts 5 form a sag from below under the seat. After being placed in the chair, the arms alternately grab portions of the shoulder straps 2 above the shoulders, pull these straps and put on the shoulders. Free access to belts is provided. After that fasten the lock 4 fixation of the shoulder and waist belts with each other.

2. Without seat lift

After the lock 4 is opened, the user pulls the loop 6 up, which pulls the flexible tapes 9 connected to the additional belts 5. Additional belts 5 flow through the windows at the top of the frame at the level of the head, on the sides of it, and lift and divert to the sides of the main shoulder belts 2.

The same can be done after leaving the chair or immediately before boarding it. After being placed in the chair, the arms alternately grab portions of the shoulder straps 2 above the shoulders, pull these straps and put on the shoulders. The loop 6 in this case returns to its original state and rests against the edge of the swivel seat 12 with a stop jumper 8. Free access to the belts is provided. After that fasten the lock 4 fixation of the shoulder and waist belts with each other.

The sequence of steps is exemplary and allows you to rearrange, add or perform some operations at the same time without losing the ability to fasten the user.

Industrial applicability

The proposed vehicle seat can be performed by a specialist in practice and, when implemented, ensures the implementation of the declared purpose. The possibility of being implemented by a specialist in practice follows from the fact that for each feature included in the utility model formula on the basis of the description, the material equivalent is known, which allows us to conclude that the criterion of "industrial applicability" for the utility model is met.

In accordance with the proposed utility model, a prototype vehicle seat for the Mi-8 helicopter paratrooper was manufactured.

Results of preliminary screening tests and the first stage of work on creating a prototype

Preliminary screening tests were conducted with the participation of two testers. As clothing and wearable equipment were used:

- combined arms demi-season suit, size 50, height 3 (2011 edition),

- wool blend sweater,

- T-shirt with short sleeves,

- carrying with a set of pockets for ammunition and equipment,

- winter hat, size 60,

- metal helmet.

As a result of the sit-down tests, the following fundamentally new set of properties for vehicle seats was revealed, namely, the possibility of lifting the shoulder straps when folding the seat to form free space for an unhindered fit in the seat. The work also showed the possibility of a comfortable grip with hands and putting on the shoulder and other belts and fastening the lock.

Thus, due to the fact that the chair contains additional belts for lifting the shoulder belts up and to the sides, connected at one end with the shoulder belts, and at the other ends with a means of tensioning the additional belts for lifting the shoulder belts, a technical result is achieved, namely, improving the comfort placing the user of the vehicle on the seat and fastening it with belts and thereby increasing safety.
