Description

Technical Field

[0001] The subject matter of the present invention The subject matter of the present invention is a side wall or door of a vehicle designed to protect against intruding structural elements during a collision in the event of a motor vehicle accident, provide protection from neck and head injuries caused by sudden shaking of the seat belt, and protect the legs.

Summary of the Invention

Means for Solving the Problems

[0002] This is achieved by providing a truss force transmission system in the central belt line having braking slides, chain guides, crumple elements and swing ribs, the elements of the system being as follows: - A truss (1) welded from below to a rigid window frame with hinges, - Three pairs of hinged structures (2a, 2b, 2c) connected to the bottom surface of the truss (1), - Three swing ribs (3a, 3b, 3c) suspended from the hinged structures (2a, 2b, 2c), Here, during a collision due to an accident, the suspended swing ribs (3a, b, c) can move by means of deformation resistance, which is that of outer crumple elements (5a, 5b) and inner crumple elements (6a, 6b) of a specific size guided by a guide chain (4) moving in the same way, whereby a passive protection system for the braking slide is realized, where the braking slide is effected by a calculated decelerated change of direction controlled by the chain (4) during a collision due to an accident. Protection of the legs is achieved by its high position and the crumple elements guided by the chain, so that, as shown by the dotted line in Figure 4, a crumple zone is formed with a maximum depth (8b), height (8a) up to a plate with a maximum thickness of 1.2 mm, whereby the intruding element can pass under the legs, avoiding neck and head injuries caused by strong pulling via the belt, as well as contact with the legs and leg injuries.

[0003] An advantageous aspect of the present invention is that the door locking mechanism of the truss (1) is fixed at four points and the minimum thickness of the welded material is at least 3.4 mm. Furthermore, the present invention advantageously provides that the welded hanging two-axis hinged structures (2a, 2b, 2c) are further equipped with additional welded reinforcing plates, the minimum wall thickness of the reinforcing plates being 4.3 mm for single-sided welding and 5.2 mm for double-sided welding. In addition, the suspended swing ribs (3a, 3b, 3c) are designed to withstand impacts primarily from the side.

[0004] Furthermore, the subject matter of the present invention advantageously provides that the uppermost chain element of the guide chain (4) is provided with holes so that the crumple elements (5a, 5b, 6a, 6b) can be connected by connecting bolts (7) (thus the uppermost chain element being the weakest chain element), and the uppermost chain element is made of a thicker material or more alloyed steel, and is therefore able to withstand a recommended minimum breaking limit of 1.96 tons.

[0005] The subject matter of the present invention is also advantageous in preventing movement and rattle, for which movable swing ribs (3a, 3b, 3c) suspended from fixed hinged structural elements (2a, b, c) hanging from a force transmission truss and a movable chain (4) of a specific size are wedge-fixed with plastic fixing elements of a specific size, or preferably with rubber wedges, and / or fixed with screws, rivets, and / or adhesive, preferably with a silicone-based adhesive, and the fixing is done so as not to impede movement.

[0006] Application Fields: The subject matter of the present invention can be applied to fields where the human body is exposed to injury caused by collision or impact, such as equipment for the storage and transport of explosive materials and structures, and automobiles and all other vehicles that are at risk of collision, and where it is necessary to reduce the speed of impact or avoid impact in a controlled manner.

[0007] Conventional technology The fundamental structural principles of passive safety in modern automobiles were established around the 1970s by Bela Barenyi, a Hungarian-born engineer at Mercedes (Daimler-Benz). The essence of his solution, in the case of passenger cars, was a three-layer structure: a deformable crumple zone, a sturdy passenger compartment, and another deformable crumple zone.

[0008] However, at high speeds, these crumple zones often fail to provide adequate protection. This is because, in the case of a more powerful or side-impact collision, the penetrating parts and structural elements of the colliding vehicle can reach the sturdy occupant compartments of the other vehicle and, further through the seatbelts, inflict fatal injuries to the body (neck fractures, rib fractures, internal organ ruptures), and the invading structural elements can also cause serious leg injuries. In a side-impact collision, it is primarily the chassis elements (the most common being the MacPherson strut chassis) that penetrate the occupant compartment: both the pushed-back chassis elements of one's own vehicle and the invading chassis elements of the other vehicle.

[0009] Objective of the present invention To resolve this, a solution that controls and slows down intruding structural elements would be desirable. This solution would avoid collision with the human body without significantly hindering the further progress of the intruding structural elements. This is in contrast to conventional reinforcements placed at the ends in the front-to-back direction, which instead allow the intruding elements to slide, deflect, and slow down without obstructing them, guiding them outward and allowing them to pass through, while simultaneously ensuring protection of the legs.

[0010] Solution of the present invention According to the solution of the present invention, intruding structural elements pass under the foot, which is raised high by the footrest. This is evident from the dimensions of the discharge zone, which are shown by the dotted line in Figure 4.

[0011] The subject of this invention is the realization of passive protection in a single system. This system, in contrast to the prior art, provides protection in collisions from any direction.

[0012] The solution according to the present invention does not have a lower, end-reinforced sill as a support in the front-rear direction, nor does it have a support reinforced in the lateral direction, so that chassis elements entering from the front or side can extend their path toward the door, i.e., move toward the rear.

[0013] There, a swing rib suspended from a force-transmitting truss (Figure 2-1) below the window is pushed backward by the reaction of a crumple element (deceleration is controlled), thereby realizing the principle of braking slide. The connection of this system is securely achieved by welded two-axis hinges and bolted fasteners. The backward movement is controlled by a chain.

[0014] The aim of this invention is to realize a three-dimensional controlled braking slide.

[0016] Advantageous exemplary embodiments and solutions 1. Advantageous embodiment of the rearview mirror: It is beneficial to weld a bolt-on aluminum housing for the rearview mirror because, in the event of a rollover, it becomes part of the crumple zone. Each one will stack up, resulting in an increase of 15-20 cm outwards.

[0017] 2. Embodiments of hinge design: The two lower hinges fit over the receiving hinge pins, while the upper hinge is advantageously mounted in the reverse configuration to prevent detachment. The hinges are connected to the frame using short, flat iron stems, which allows the frame to be easily enclosed on all sides with thin sheet metal covers (see Figure 9).

[0018] 3. Exterior Panel Design: A favorable embodiment of the exterior panel of the door is a simple box structure. Only the four upper corners are welded. This is because the upper portion needs to be functionally separated from the lower portion. The lower sliding zone must be easily movable or open smoothly. According to one favorable embodiment, the door panel consists of four elements: an inner panel with a maximum thickness of 1.2 mm, an upper exterior panel of 3 mm, a lower exterior panel of a maximum thickness of 1.2 mm, and a lower panel of a maximum thickness of 1.2 mm. The recommended material is stainless steel sheet, and with this stainless steel sheet, stainless steel bolt fasteners (one of the best embodiments is a flanged D-head hex socket type) are used. The upper exterior panel (3 mm) is sufficiently rigid so it does not need to be folded back in the window frame to form a flange. The line numbered 8 in Figure 5 indicates the lower edge of the upper portion.

[0019] 4. A preferred and advantageous embodiment of the lower window is to screw it to the frame rather than glue it. The window material should preferably be a polycarbonate sheet with UV resistance.

[0020] 5. An advantageous exemplary embodiment of the upper window glass: Due to the structural design, it is not possible to lower the window panes. Figures 2, 5, and 14 show preferred sliding window designs, but pivot windows that tilt up and down are also possible. The side windows of the Citroën 2CV "Duck," or certain solutions in American RVs, are good examples of this solution. The groove of the sliding window (i.e., a U-shaped rail to which the sliding window is attached and can slide) with the front and rear sealed has drainage outlets on the front and rear bottom surfaces. Small tubes are welded and attached to these drainage outlets, and a rubber tube is connected to this tube from the bottom, so that possible rainwater, car wash water, or dew condensation water is guided through the lower door panel (as shown in FIGS. 11 and 12).

[0021] 6. Another preferred embodiment of the upper window glass: The outer window groove is firmly bolted to the reinforced window frame, and the window frame is covered with a silicon adhesive for sealing (over the entire circumference). The inner window groove can be moved inward from the vertical surface of the window frame at the front (since this window must also function as an emergency exit). At the rear, this inner window groove can be pivoted around a fixed pin. This pin has a drainage hole, a nut, a spring washer, and a flat washer. The pin with the lower drainage hole and the upper bolt with a pin form a pivot axis. At the front, after tilting the spring rubber sealing end cap of the groove and pushing the glass forward, the end cap folds up and down, making the glass removable. This enables easy escape (e.g., during a rollover). To pivot the inner window glass from its basic position, the front drainage rubber tube must be left longer (cut to an appropriate size). Fixing of the inner groove: The inner groove is fixed by a flat metal piece with holes welded in front of the groove. This metal piece is manually bolted to the inner edge of the window frame with a wing nut screw, but first, the synthetic leather trim with foam attached, whose upper part is fixed by a small pin, is folded down. The materials, shapes, dimensions, and designs of various components can be advantageously selected according to requirements.

[0022] As a preferred exemplary embodiment, in an off-road baby stroller or a cycle trailer for carrying children, instead of rubber springs, flexible and non-breakable plastic parts can be used.

[0023] As a preferred exemplary embodiment that can be used in a space shuttle or its safe return capsule, a titanium alloy can be used.

[0024] Preferably, as a crimping element, a recessed plate element of a specific size, a spring, or even a rubber ball can also be used.

[0025] The present invention is not limited to the preferred embodiments, and the scope of protection extends to embodiments of the principle of the solution according to the present invention.

This facilitates the understanding of the concepts of the present invention and makes it easier to interpret the advantages of the embodiments. These figures are not to scale, and the positions of each embodiment are depicted according to their arrangements within the vehicle.

[0028] Advantages of the present invention 1. The braking slide system according to the present invention can reduce the number of traffic accident fatalities to less than 1%, even in high-speed collisions. In the conventional reinforced sill solution, this percentage increases significantly because the reinforcement is mainly applied to the edges (see Figure 3). Furthermore, additional longitudinal tubular reinforcements are attached to the door to prevent crushing.

[0029] 2. Systems related to conventional technology are not safe, especially in the case of lightweight vehicles (e.g., microcars).

[0030] 3. The braking slide system according to the present invention provides higher safety. This is evident from the statistical data. [Explanation of Symbols]
