Said safety insert is made in the form of a shaped one, formed of polypropylene, structured as a honeycomb array, lateral, orthogonal to the ribs of the honeycomb, the periphery of which is equipped with fixing paws with eyes. The insert is made fixedly attached to the inner panel of the door by means of bolted joints extending through the eyes of the mounting paws.

From the patent for utility model RU 85131, 6 IPC 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 safety insert, according to this utility model, is made in the form of a shaped array formed of expanded polypropylene, a side array, relative to the end facing the upholstery, 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 in accordance with the coordinates and geometrical dimensions of the mounting legs and eyes 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.

The disadvantages of the solutions RU 58472 and RU 85131 should be 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.
