Description

Technical Field

[0001] The present invention relates to the field of aviation seat design, and specifically to an adjustment and crashworthiness mechanism for an anti-crash seat protection component. Background Art

[0002] The structure of a helicopter anti-crash seat usually consists of a protection component, a seat pan component, a skeleton component, etc. An energy absorption device is often included in the anti-crash seat skeleton component to provide crash protection for the occupants. The seat pan component provides an installation interface for the protection component, and at the same time, it is required that such an anti-crash seat protection component must have high safety and be convenient to use.

[0003] After retrieval, the existing patent (publication number: CN218907611U) discloses a new type of lightweight armored anti-crash seat, including a seat pan component, a seat skeleton, a height adjustment mechanism, and an anti-crash component. The seat pan component includes an integrally formed seat pan bottom and a seat pan backrest. The seat pan bottom is covered with bulletproof armor. The seat skeleton includes columns, an upper sliding seat, a lower sliding seat, and a height adjustment plate. The upper sliding seat and the lower sliding seat are installed on the columns. The height adjustment plate is connected to the anti-crash component and is installed between the upper sliding seat and the lower sliding seat. The height adjustment mechanism is connected to the height adjustment plate; a slide rail is provided on the outer side of the seat pan backrest, and the upper sliding seat and the lower sliding seat are installed on the slide rail. Although this patented technology has successfully reduced the seat weight from 37.5 kg in the prior art to 30 kg now, with a weight reduction of 20%, there are still problems that the traditional anti-crash seat armor component is usually fixedly connected to the seat pan component, does not have an adjustment function or the adjustment function steps are cumbersome, and the armor component does not have crashworthiness performance. Therefore, those skilled in the art have provided an adjustment and crashworthiness mechanism for an anti-crash seat protection component to solve the problems raised in the above background art. Summary of the Invention

[0004] 1. Technical Problems to be Solved In view of the deficiencies of the prior art, the present invention provides an adjustment and crashworthiness mechanism for an anti-crash seat protection component, which solves the problems that the traditional anti-crash seat protection component is usually fixedly connected to the seat pan component, does not have an adjustment function or the adjustment function steps are cumbersome, and the protection component does not have crashworthiness performance.

[0005] 2. Technical Solutions To achieve the above objectives, the present invention is realized through the following technical solutions: An adjustment and crashworthiness mechanism for an anti-crash seat protection component, including a protection component; a framework is provided on the back surface of the protection component, the protection component includes a protection adjustment mechanism and a crashworthiness mechanism, the protection adjustment mechanism includes a protection plate, an upper protection slide rail and a lower protection slide rail, the crashworthiness mechanism includes a protection connection seat, a limit pin is arranged inside the protection connection seat, a protection installation guide rail is fixedly connected to the outer surface of the protection connection seat, a seat pan is arranged on one side surface of the protection installation guide rail, a protection energy absorption plate is arranged on the inner wall of the protection installation guide rail, energy absorption plate installation screws are arranged on the outer surface of the protection energy absorption plate, an energy absorption plate reinforcement plate is arranged on the outer surface of the protection energy absorption plate, energy absorption plate rivets are arranged on the energy absorption plate reinforcement plate, the number of the energy absorption plate rivets is set to four groups, and a protection component quick release pin is arranged inside the protection installation guide rail.

[0006] Through the above technical solution, by aligning the installation holes of the energy absorption plate installation screws with the installation holes of the energy absorption plate reinforcement plate and connecting them with the energy absorption plate installation screws, one end of the protection energy absorption plate is riveted to the protection connection seat, and the other end is connected to the protection installation guide rail by the energy absorption plate installation screws. Furthermore, the limit pin restricts the continuous sliding of the protection installation guide rail, which can prevent the abnormal operation of the protection energy absorption plate. When a crash occurs, the limit pin is cut off, and at the same time, the protection energy absorption plate deforms inside the barrier to absorb energy, so that during the crash process, as the energy absorption mechanism of the anti-crash seat plays a role, the crashworthiness mechanism can additionally absorb energy.

[0007] Furthermore, the protection connection seat is threadedly connected to the seat pan by screws, the number of the energy absorption plate rivets is set to four groups, and the energy absorption plate reinforcement plate is riveted to the protection energy absorption plate by the energy absorption plate rivets.

[0008] Furthermore, the protection energy absorption plate is riveted to the protection connection seat by the energy absorption plate rivets, and the protection installation guide rail is in the form of an I-beam and is slidably connected inside the groove of the protection connection seat.

[0009] Furthermore, a spring and a snap ring are respectively arranged on the inner wall of the upper protection slide rail, a bracket is arranged on the back surface of the protection plate, and a slider is arranged on the back surface of the bracket.

[0010] Furthermore, a positioning piece is arranged on the inner wall of the bracket, a guide post sleeve is inserted into the protection plate, and an adjustment locking piece is fixedly connected inside the spring.

[0011] Furthermore, the protection plate is fixedly connected to the upper protection slide rail and the lower protection slide rail respectively, the number of the sliders is set to two groups, and both groups of sliders are fixedly connected to the bracket.

[0012] Furthermore, the number of the brackets is set to two groups, and both groups of brackets are fixedly connected to the protection installation guide rail.

[0013] Furthermore, the two sets of sliders are respectively slidably connected to the inner walls of the upper protective slide rail and the lower protective slide rail.

[0014] Through the above technical solution, the two sets of sliders move horizontally along the upper protective slide rail within the two sections with limited positions, i.e., the upper protective slide rail and the lower protective slide rail that prevent the sliders from sliding out. Hold the protective component with one hand and press the adjustment locking piece longitudinally along the upper protective slide rail. At the same time, the protective component can be moved horizontally along the protective installation guide rail. Release the adjustment locking piece, so that the adjustment locking piece can automatically reset under the action of the spring to realize the locking of the convex locking pin of the adjustment locking piece and the locking hole of the positioning piece. In this way, by combining the adjustment and anti-falling functions of the protective component, the structure is simple, and the front and rear positions of the protective component can be adjusted with one hand, which can greatly improve the convenience of adjusting the protective component and the survival rate of the crew.

Based on the specific implementation manners of the present invention, all other specific implementation manners obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.
