Description

The utility model relates to means of passive protection of a passenger of a vehicle in case of a side impact.

From the patent for utility model RU 85131, 6MPK B60R 21/02, B60J 5/04, publ. 07.27.2009, a vehicle door is known comprising an inner panel, a door trim and a security insert located between the inner panel and the door trim. The security insert, according to this utility model, is made in the form of a shaped array formed of expanded polypropylene, an array, lateral, relative to the upholstery end face, the periphery of which is equipped with fixing paws with eyes. The door trim is equipped with means for securing the safety insert, made in the form of bosses formed on its surface located on the side of the door. The bosses are made formed in accordance with the coordinates of the location and geometric dimensions of the mounting paws and eyelets of the safety insert. In this case, the insert is made installed on the bosses of the door trim and is motionlessly connected to the bosses by means of ultrasonic welding.

As a disadvantage of this solution, it is necessary to highlight the increased cost of manufacturing the door due to the use of additional fasteners during the door assembly process and an additional technological operation providing mutual fixation of the safety insert and door trim.

From the application for invention US 20120038182,6MPK B60J 5/04, publ. 02.16.2012, the car door pillar trim and safety insert are known. The safety insert is made in the form of a molded array made of foamed polyurethane equipped with parallel-located sockets, and the upholstery of the rack is equipped with safety insert fasteners made in the form of bosses, according to the number of insert sockets formed on its surface facing the rack. The insert is made mounted on the bosses of the door trim with the possibility of its retention on the bosses by means of friction. The reliability of the retention of the insert in the upholstery of the rack is ensured by the use of elongated lugs compared to the solution according to patent RU 85131. Moreover, based on the possibility of deformation of the safety insert during a side impact of an automobile against an obstacle, the bosses, in the decision according to the cited application, are made mainly orthogonally located relative to the transverse geometric axis of the automobile.

With regard to the car door, due to its relatively small thickness and saturation with functional devices and parts, the use of elongated bosses formed on the door trim is not acceptable.

The objective of the utility model was to create a door door trim that is safe to hold the safety insert after the positioning operation of the insert on the door trim (without using any additional fasteners and technological operations).

As a prototype, a decision was made according to patent RU 85131.

The problem is solved in the upholstery of a car door containing means for securing the safety insert.

The problem is solved in that:

means for securing the safety insert are formed by the protrusion located on the side of the insert, the first and second sockets, as well as the L-shaped hook containing a single, stand and shelf, where the hook shelf is made remotely located relative to the upholstery;

- upholstery sockets and hooks are configured to position two safety paw fastening paws in the upholstery sockets and to accommodate a third safety paw fastening paw in the interval between the hook flange and the upholstery, as well as resting against the surface of the hook flange facing toward the upholstery;

- the protrusion of the door trim is arranged to block the movement of the safety insert relative to the surface of the trim after completion of the positioning of the fixing legs of the safety insert in the seats of the trim.

The utility model can be implemented in the upholstery of 1 door (door not shown) of a car made in the form of a molded elasto-plastic shell made of plastic by injection molding, equipped with means for securing the safety insert, configured to hold the safety insert 2, made in in turn, in the form of an array made of foamable material in the injection mold, lateral, relatively facing the upholstery, the periphery of which is provided with three, first 3, second 4 and third 5 (num conventional radio) arranged distanced fixing paws, and accesses the door trim 1, a surface provided with a projection 6. In this case the first 3 and third 5 2 Safety insert formed oppositely disposed legs.

The security insert fastening means are formed by two, the first 7 and second 8 (conventional numbering), sockets and a protrusion 9 formed on the upholstery surface 1 facing the insert 2, as well as a hook located on the upholstery surface 1 facing the insert. The hook is made L-shaped containing the rack 10 and the shelf 11. Design features of the implementation of the hook does not affect the essence of the claimed utility model. The hook can be formed integrally with the upholstery (not shown), and as a separate part (not shown), mainly in the form of an element of a functional device that is part of the door trim (shown in the illustration of Fig. 2), for example, as an element of an additional shell 12, by means of which a pocket is formed in the door trim 1. Slots 7, 8 and the hook are arranged spaced. The geometric characteristics of the sockets 7, 8 and the hook, as well as the coordinates of their location, are made in accordance with the geometric characteristics and the coordinates of the mounting legs 3, 4, 5 of the security insert 2 being mated to the upholstery. In this case, the first socket 7 and the hook are made oppositely located, the hook is made with the orientation of its shelf 11 towards the opposite of the socket 7, as well as with the distance of its shelf 11 from the surface of the upholstery 1.

Oppositely located first nest 7 and the upholstery hook are arranged to position opposite first 3 and third 5 fastening legs of insert 2, respectively, in the first nest 7 and in the interval between the flange 11 of the hook and the upholstery 1, and also with the third fastening foot 5 adhering to facing the upholstery 1 surface of the flange 11 of the hook. Located in the interval between the first 7 nest and the hook of the upholstery, the second 8 nest of the upholstery 1 is arranged to accommodate the second mounting paw 4 of insert 2 in the socket, which, in turn, must be located between the opposite first 3 and third 5 mounting paws.

The protrusion 9 of the upholstery 1 is made formed and positioned with the possibility of positioning the fixing legs 3, 4, 5 of the safety insert 2 in the sockets 7, 8 and under the hook shelf 11, as well as with the possibility of the security protector insert 2 protruding from the protrusion 6 to counter the movement of the insert in the opposite mounting direction after completing the mutual positioning of the upholstery 1 and the safety insert 2. In this case, the upholstery 1 is partially fit to the surface of the safety insert 2 facing the door and after completing the positioning of the fixing legs 3, 4, 5 of the safety insert 2 in the sockets 7, 8 and under the shelf 11 of the hook of the upholstery 1.

The operation of the utility model, as well as the features of its design, can be shown with maximum completeness only when a joint examination of the claimed door trim and the safety insert mating with the trim is combined.

The utility model works as follows:

Before the final pairing of the door trim 1 and the safety insert 2, the latter is applied with the surface facing the upholstery to the corresponding surface of the trim 1 with the first 3 and second 4 fastening legs being oriented in the direction of the respective upholstery slots 7, 8, as well as with the third 5 fastening foot being oriented in the direction under the shelf 11 hook.

Then, by moving the security insert 2 along the corresponding surface of the door trim 1, the first 3, second 4, and third 5 fastening legs are inserted into their corresponding slots 7, 8 and under the hook shelf 11, after which the insert 2 is sent to its final location. In this case, the protrusion 6 of the safety insert 2, encountering, as the insert 2 is moved relative to the surface of the upholstery 1, correspondingly located to it, the protrusion 9 of the door trim, sliding over the surface of the protrusion 9 of the trim 1, elastically deforms the trim 1, which allows the operator interfacing the insert 2 and upholstery 1, move insert 2 to its final location. As the safety insert 2 moves toward its final location, providing for the location of its mounting legs 3, 4, 5 in their respective slots 7, 8 and under the hook shelf 11, the protrusion 6 of the safety insert 2, sliding along the surface of the protrusion 9 of the upholstery 1, descends from the ledge 9 of the upholstery (as an option - it moves away from the ledge 9 of the upholstery). The upholstery 1, assuming its initial state, moves the protrusion 9 of the upholstery toward the surface of the safety insert 2 facing the upholstery 1, which, in turn, prevents the spontaneous movement of the insert in the opposite direction.

The safety insert 2 is fixed against movement relative to the surface of the upholstery 1. The orthogonal movement of the safety insert 2 relative to the upholstery 1 is excluded by the location of the first 3 and second 4 mounting legs of insert 2 in the seats of the upholstery 1, third 5 of the mounting foot under the flange 11 of the hook, with the opposing upholstery 1, the surface of the third mounting foot 5 to the flange 11 of the hook, as well as a partial fit facing the upholstery 1 surface of the insert 2 safety.
