Abstract

FIELD: vehicles.

SUBSTANCE: invention relates to a vehicle seat, particularly an infantry fighting vehicle. Vehicle seat consists of hinged backrest frame and cushion frame. Backrest fabric and seat fabric are made of multilayer fabric woven from aramid fibers, it serves as splinter protection for crew and landing force in vehicle. Backrest fabric is detachable along axial vertical line for boarding of a member of a landing party with knapsack or rucksack and is equipped with a zipper, and/or hooks, and/or rivets-eyelets for its closure. Seat back frame is attached to vehicle body. Seat frame is equipped with a spring providing the cushion adjoining to the backrest without a load and holding the knapsack or the rucksack in the niche.

Description

The technical solution, declared as an invention, is intended for use in vehicles, aircraft and vessels, in particular, military vehicles - infantry fighting vehicles (armored personnel carriers), and provides an increased level of protection for the landing force and crew.

The technical result is an increase in the level of protection of the vehicle crew and troops.

The seat design is known [1, 8109563], which is a combination of belts and straps holding the said seat. It resembles a common folding seat without a back and therefore non-functional even over short distances of landing. The seat design is somewhat more convenient [2, 8801099]. A folding, easily transformable seat, but with a load in the form of a person in full gear and a backpack does not look reliable and durable. Most likely, the concept, the general appearance of a possible seat design, is patented. The same comments can be attributed to the design of a suspended seat [3, 7513558], positioned as a safety seat.

The functionality of the suspended seat can be described differently [4, Puma]. The practical applicability, strength and durability of the design are quite obvious. But for a paratrooper in full gear, including a backpack/knapsack, the presented suspended seat model is unacceptable due to the blind back.

The applicant considers the closest analogue to be the “Safety Seat” [5, 2013234480], which has a seat frame and backrest suspended on a strong belt.

In addition, as the source [7, "Tankodesant"] testifies, the time spent on landing the troops is of great importance. In this case, the reliable fastening of the paratrooper [6, "Rescue chair"] and the rapid disconnection of the lock when leaving the vehicle are of paramount importance, when every second counts: "The APC will stop, the doors will open, everyone will get out, run and form a chain" [7].

The claimed “Vehicle Seat”, in the opinion of the applicant, is more acceptable, performing the functions of protecting the paratrooper and ensuring mobile evacuation from the said vehicle.

The implementation of the claimed “Seat..” is shown in Fig. 1, Fig. 2, Fig. 3 and has the following positions:

1 - frame of the seat cushion and backrest structure, providing the geometric dimensions and strength of the structure, allowing for the placement of a paratrooper, a knapsack or backpack, and a personal weapon;

2 - seat cushion made of multilayer fabric woven from aramid fibers;

3 - a seat back made of the aforementioned aramid fabric, the function of which is to ensure the seating of a paratrooper with a knapsack or backpack and having the ability to close the front parts of the fabric with a zipper or hooks or lacing to support the back when the paratrooper is seated without a knapsack or backpack;

4 - retaining straps secured at points on the seat frame;

5 - detachable lock of retaining belts;

6 - projection of the parting line of the front parts of the seat back fabric.

The seat cushion and backrest, triangular inserts on the sides, made of the mentioned fabric from layers of aramid fabric [8], [9], serve as additional protection for the crew and troops in the vehicle. The backrest, as indicated above, is made in the form of panels with the ability to tighten (zip, hooks, lacing, etc.) the edges of the panel along the vertical axis.

In Fig. 2, pos. 7 is a knapsack or backpack; pos. 8 illustrates the placement of a bracket for placing and transporting the paratrooper’s individual weapon.

Fig. 3 illustrates the placement of a knapsack or backpack in a niche formed by the backrest and an automatically raised cushion when there is no load on it.

Thus, a seat for vehicles, aircraft and vessels, in particular, a military vehicle - an infantry fighting vehicle (armored personnel carrier), is declared, which helps to increase the level of protection of the vehicle crew and troops while ensuring the declared technical result, previously unknown in the declared combination of features and corresponding to the criteria of an inventive step and industrial applicability.
