Description

The invention relates to systems and devices for securing cargo in the cabin or in the luggage compartment of a car and is intended to prevent the movement of goods in the direction of people in the cabin during an emergency, accident, emergency braking and in other cases.

The patent RU 140944 is known from the prior art, which describes a device for fastening objects in a vehicle, comprising a belt with Velcro textile tape fastened at the ends with micro hooks. It should be assumed that this method of securing the cargo may be appropriate only for a more convenient arrangement of things (some of which may have a restriction in vertical-horizontal arrangement), but this method of securing is ineffective in the case of, for example, an accident when all previously secured objects are inertia strive to continue driving around the car.

Differences from the declared solution are that:

- The system of restricting the movement of cargo includes a frame, removed in the design of the seats;

- The system is brought into working position when the seats are folded, i.e. when objects in the luggage compartment do not interfere with moving around the car.

The patent RU 2564275 is known, which describes a multi-level system for storing things in a car, while the seat back is one of the fasteners of this system. However, this system is not intended to limit the movement of cargo towards the passengers of the vehicle during an accident, since only a retractable mesh is used to prevent the movement of cargo.

Differences from the declared solution are that:

- The system for restricting the movement of cargo has a special durable frame that prevents the movement of heavy and bulky cargo;

- The grid is used only as an auxiliary tool to hold small and light objects, and the area of each sector of the grid is small enough, which reduces the load on it.

The patent RU 52588 is known, which describes a luggage net containing an elastic frame made of a flexible tape or cord and a mesh fixed around its perimeter. It should be assumed that such a grid cannot hold a heavy or bulky cargo in an emergency, since each of the items making up the load will affect the entire grid as a whole and its fastenings, which will lead to a breakthrough of the grid and dangerous movement of the cargo around the passenger compartment.

Differences from the declared solution are that:

- The system for restricting the movement of cargo has a special durable frame that prevents the movement of heavy and bulky cargo;

- The grid is used only as an auxiliary tool to hold small and light objects, and the area of each sector of the grid is small enough, which reduces the load on it.

Known patent RU 83975, describing a device for securing objects inside the trunk of a car, containing at least two belts with Velcro at the ends. This design is not able to hold the load in case of emergency.

Differences from the declared solution are that:

- The system of restricting the movement of cargo includes a frame, removed in the design of the seats;

- The system is brought into working position when the seats are folded, i.e. when objects in the luggage compartment do not interfere with moving around the car.

In the event of an emergency during the movement of the car associated with a sudden stop, or braking, or an accident, the cargo in the car receives inertia, which makes it move in the direction of travel. If the cargo is in a closed luggage compartment or if the cargo is small in size and is behind the seat in the luggage compartment (for cars with a body where the luggage compartment is part of the passenger compartment), then in the event of an emergency, the rear seat is a natural restraint for its movement.

But, in cases where the size of the cargo or its quantity does not allow it to be safely positioned behind the seats in the luggage compartment, a dangerous situation arises when the cargo is located in the passenger compartment with the rear seats folded down, and in some situations the car interior can be loaded to the ceiling.

If an emergency occurs, this load will start by inertia moving towards the people sitting in front, as a result of which people sitting in front can be injured. At the same time, luggage nets and belts by their characteristics are not capable of guaranteed to hold the load in place.

The technical result of the claimed invention consists in creating a system that would be able to limit the movement of heavy and bulky cargo, as well as small, light objects and not allow them to cause injuries to people inside the vehicle.

The technical result is achieved with the help of a sturdy frame removed in the seats and folding if necessary, which in some cases can be covered with a net.

Special cases of manufacturing a system for restricting the movement of cargo in a passenger car in an emergency are:

- Production of a system without nets;

- Extension of the system without the need for folding seats;

- Location in the design of retractable elements that increase the area of contact of the system with the load.

Brief Description of the Drawings:

FIG. 1 - A seat with an installed system in the seatback;

FIG. 2 - Seat with installed system (rear view);

FIG. 3-Front and rear seat. The system is in working position;

FIG. 4 - Rear view of a folded seat with the system in working position;

FIG. 5 - A fragment of the design of the system. Internal elements;

FIG. 6 - Front and rear seat. System installed in the bottom seat cushion;

FIG. 7 - Front and rear seat. The rear seat is folded upside down; the system is in working position.

The following elements are indicated on the images of the system for restricting the movement of cargo in a passenger car in an emergency:

1. Lower seat cushion;

2. The backrest;

3. Headrest;

4. Horizontal elements of the frame;

5. Vertical elements of the frame;

6. Mesh;

7. The floor of the car;

8. Cargo (shown as boxes);

9. Cord;

10. Roller cord;

11. Internal retractable element.

The system for restricting the movement of cargo in a car in an emergency works as follows:

Elements of the system are located in the back of the seat (2), or in the lower seat cushion (1), depending on how the seats are folded and depending on how the system extends. Thus, for example, with the seat folding method shown in FIG. 7, the system can be located not only in the seat cushion (1), but also in the backrest (2), provided that the system is extended before the seat is fully folded.

If it is necessary to load more objects in the car than fits in the luggage compartment, it may be necessary to fold the rear seats (or in some cases the rear and middle, or middle) rows.

When the system automatically extends during folding of the seat with the installed system of restricting the movement of cargo, the holding frame containing vertical (5) and horizontal (4) elements is independently pulled out of the chair for which a cord (9) or levers or rods connected to the seat mechanism are used to respond for folding it. The cord (9) passing through the roller (10) is attached to the horizontal (4) or vertical (5) element of the holding frame.

If it is necessary to forcibly fold the holding frame, the cord (9) is detached from the horizontal or vertical element (4.5) and the holding frame is folded back, even though the seats are folded.

In addition, it is possible to use other types of mechanisms for extending and folding the holding frame.

Such a possibility is provided for cars with the number of rows of seats more than two and, if necessary, the transportation of bulky cargo exceeding the length from the rear door of the car to the holding frame.

When the system is manually extended, the retaining frame extends mainly when the seats are folded, but there are possible arrangements for the frame and folding the seats in which the retaining frame extends well before folding the seat, or extends while folding the seat.

The holding frame can be connected to a part of the seat upholstery, since its location in the back of the seat can violate the overall impression of the aesthetics of the cabin. Moreover, in this case, the seat upholstery is attached to each of the frame elements and between each two frame elements and allows you to protect people in the cabin from moving small and light loads.

If the seat cover is not attached to the frame, is absent, or it is not possible to use it as a protective element, then a mesh (6) can be stretched between the frame elements. Several grids (6) can be used in the frame according to the number of cells that form horizontal (4) and vertical (5) frame elements, or one grid (6) can be used, but fixed on each frame element, and between each two frame elements .

This method of attaching the seat upholstery, or mesh to the retaining frame, can reduce the area of contact with the load, and therefore reduce the force with which the load will press on the mesh (upholstery), which will prevent it from breaking.

When several seats are folded together in a row and the retaining frames are extended, a situation may arise where the distance from the holding frame in one seat to the holding frame in the other seat is too large, which increases the likelihood that the load (8) can slip between the frames. To prevent this situation, it is provided that the horizontal (4) elements of the frame can consist of two parts (one of which is a connecting element) connected by means of movable hinges, or horizontal elements (4) will have a hollow space inside which the sliding connecting element will be placed element (11).

The retractable element (11) extends from the horizontal (4) element of one holding frame and can enter the hollow space of the horizontal (4) frame element of the adjacent seat. Thus, the holding frames are interconnected, which increases their resistance to loads, and also creates an additional obstacle to the load, which excludes its movement between the holding frames. For additional protection of the people sitting in front from light and small loads, a folding grid can be used, which has fastenings on the pull-out element (11) and folds out when the pull-out element (11) is activated.

An example of the operation of the system for restricting the movement of cargo in a car in an emergency:

For example, we give the following situation:

A car loaded with cargo in the folded back seat collides with a chipper at a speed of 60 km / h. The speed of the car drops sharply to 0 km / h, while the load receives an acceleration approximately equal to the speed of the car before the collision.

In the absence of a system, the load (8) moves forward, while only those items that were behind the backs of the front seats are delayed. But the load on the backs of the front seats can lead to their deformation, and the load that was outside the backs can reach the frontal and, in addition, with uncontrolled movement of the load, it can reach parts of the person’s body that are not protected by the back of the seat (2) or are weakly protected by the back of the seat and headrest (3). These parts of the body include human hands, neck, head. Moreover, neck and head injuries can be deadly in such a situation.

In the presence of the system, the load (8) moves forward when it encounters an obstacle in the form of a holding frame and inside the frame cells formed by horizontal (4) and vertical (5) elements of the frame, mesh or a fixed part of the seat upholstery. In this case, a large load is held by vertical (5) and horizontal (4) frame elements, and a light and small load is held by a net (6) or seat upholstery.

Features of the invention:

1. Materials for the manufacture of a system for restricting the movement of goods may be different. It is mainly assumed that steel or high-strength aluminum will be used as the material of manufacture, but the main task of the frame is to hold the load, so it is possible to use other materials. For example, for design purposes, a tree with a core of metal can be used, and high-tech materials such as plastic, carbon fiber and other composite materials can also be used. It is also possible to use several materials simultaneously.

The fabrication material of the mesh (6) may also be different. The mesh (6) may be made of threads or ropes intertwined, or may be made of plastic by molding. This is possible since the grid (6) located on the frame is not provided for permanent folding, but it is desirable that it provides the possibility of viewing through the salon rear-view mirror. Therefore, the mesh structure can be made of almost any material.

2. In FIG. 3 under No. 8, the cargo is indicated in the form of rectangular boxes. In a real situation, the type of cargo may differ significantly from the image. In particular, the cargo may have a non-standard shape with protruding parts. The task of the holding frame is to provide the ability to hold various types of cargo, various shapes and sizes. But, given that, with small dimensions, the cargo is predominantly lightweight, it is assumed that the grid (6), which has fasteners that allow the load to be distributed, can impede the movement of such goods. The holding frame in this case is intended to hold a larger and heavier load, as well as to secure the mesh or seat upholstery.

3. Even if there is a system for restricting the movement of cargo, some of the items can move to the front of the car where people are located. This can happen if a small load is distributed in areas of the passenger compartment where there is no holding frame and net (6) or seat upholstery. And also in the case of a breakthrough of the mesh or seat upholstery, but when a breakthrough of the mesh (6) or seat upholstery, the inertia of the load is inevitably lost and the speed of its further movement drops, which also protects the people sitting in front from injuries.

4. In addition to the horizontal (4) and vertical (5) elements of the frame, elements can be applied diagonally and at a certain angle relative to the floor of the passenger compartment.

5. The holding frame can be located in only one seat, in the back row of seats, as well as in the rear and middle, or middle, rows of seats.
