Abstract

An object of the present invention is to produce a portable air-seat type leg rest that supports legs in front of and behind the knee at an appropriate position, and tires the legs of passengers whose knees come out of the seat in the long-term use of aircraft economy class seats. And reduce swelling.
SOLUTION: An air sheet portion 1 and a seat portion 2 that holds an appropriate position when used are provided, and a plurality of parabolic flat belt-like connecting bodies are provided on the upper and lower inner walls of the air sheet portion in a direction parallel to the knee vein blood circulation. This is a portable air-seat-type legrest that has an internal pressure and tension that can support the front and rear legs of the knee that come out of the seat, and that can reduce blood stagnation. When used for a long time, fatigue and swelling of the legs of the passengers whose knees come out of the seat are reduced.

Description

  The present invention is a portable air seat legrest for reducing fatigue and swelling of a passenger's leg whose front and rear legs are located in front of the seat when the aircraft economy class seat is used for a long time.

For aircraft economy class seats, seats developed for ease of sitting are used, but for passengers with relatively long legs, the knees protrude beyond the seats, and the space in front of the seats is narrow. In addition, knees and ankle joints always bend, compressing knee veins and stagnation of blood, causing swelling and fatigue of both legs due to long boarding. The countermeasure is to reduce the load on the knee joint and ankle by keeping both legs at the height of the knee, extending the ankle and knee, or using a seat that can sit deeply near the knee. .
For this purpose, an air seat or legrest for carrying with the purpose of reducing the load on the knees and ankle joints due to the weight of the legs protruding from the seat without impairing the function of the structure taking into consideration fatigue prevention etc. of the aircraft seat itself. Is desired.

  In long-distance flight, it is necessary to reduce the load on the knee joint and ankle by supporting the weight of the legs before and after the knee that protrudes from the seat without impairing the function of the aircraft seat itself. Therefore, it should be light enough to be carried as a carry-on product, be able to support the weight of the legs before and after the knee, and be structured so that the position of the supporting part is properly applied to the legs around the knee. Furthermore, there is a need to solve the problem of a structure that does not stagnate blood by continuously pressing the knee vein.

  The portable air seat leg rest of the present invention is a single seat laid on the lower seat of the buttocks so that the air seat portion supporting the leg weight before and after the knee protruding from the seat and the air seat portion are properly positioned at the front of the seat It has a structure consisting of parts. As a solution to the problem in the present invention, a simple air sheet and a sheet structure are adopted to reduce the weight for carrying. Next, regarding the problem of obtaining a structure that can support the load of the legs including the knee without impairing the seating comfort of the aircraft seat itself, a plurality of rectangular belt-like connections between the upper and lower inner walls of the air seat part supporting the legs before and after the knee The body was bonded to form a parabolic cubic air seat structure that rises toward the knee protruding from the front of the seat. As a result, the air pressure and tension in front of the air seat are increased by the weight of the leg itself, and a structure capable of supporting the weight of the leg is obtained. Regarding the problem that the air seat part does not deviate from the proper position at the front of the seat and does not impair the seating comfort of the seat itself, a single cloth-like sheet that is continuous with the air seat part is placed on the seat and pressed by the heel part. , Solving the problem. Furthermore, by providing a plurality of the above-described belt-like connecting bodies in parallel to the blood flow, the body or leg tilting to the left and right that occurs during sitting can discontinuously move the leg vein compression parts before and after the knee. Or the problem that it is the structure which produces the motion shifted up and down and does not raise | generate the continuous compression of a knee vein is solved.

  By using the portable air seat type leg rest of the present invention, it is possible to support the weight of the knee and the legs before and after the knee, and to reduce the load applied to the knee and ankle. As a result, it is helpful to reduce the swelling and fatigue of both legs of passengers whose knees are in front of the seat in an aircraft economy class seat.

  A portable air seat type leg rest which is an embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIG. 2, the portable air seat type leg rest of the present invention comprises an air seat portion and a seat portion following the air seat portion. For the air sheet portion, an elastic airtight material suitable for an air sheet such as a soft polyvinyl chloride resin having a polyester or cotton surface processed is used. As for the air sheet part, a parabolic rectangular cloth as shown in FIG. 4 or a strip of elastic material is connected at five equal intervals between the upper and lower sheets of two rectangular sheet-like airtight materials. It is provided in parallel to the position shown by the dotted line. On the side of the air sheet, the upper and lower sheets are directly bonded together, or a sheet of an airtight material with a parabolic plane is applied to form a bag shape. The sheet following the air sheet is a rectangular cloth-like material. FIG. 2 shows the completed shape when expanded. An air inlet with a check valve is provided on the side of the air sheet.

  When using the portable air seat legrest of the present invention, adjust the position of the seat part so that the air seat part inflated to 80-90% expands about 0.1m from the front edge of the seat as shown in FIG. And sit down on the seat. The air seat part following the seat part is a structure that gradually increases toward the knee, and the air pressure in the air sheet is pressurized by the weight of the legs themselves, increasing the internal pressure and tension to the front part, The leg is supported, and the burden on the knee joint and ankle is reduced.

  Embodiments of a portable air seat type legrest for an aircraft economy class seat will be described below with reference to the accompanying drawings. An elastic airtight material suitable for an air sheet such as polyvinyl chloride resin whose surface is processed with polyester or cotton is used. The size of the bottom surface of the air sheet portion shown in FIG. 2 is a rectangle having a front-rear width of 0.3 m and a horizontal width of 0.4 m. The cloth-like sheet following the air seat portion is a rectangle having a front and rear width of 0.2 m and a lateral width of 0.4 m which is a seat width. Between the inner walls of the upper and lower sheets constituting the air-seat, as shown in FIG. 4, a connecting body of a parabolic rectangular elastic material having a height of 0.05 m at the highest position and 0.02 m at the lower position is spaced at intervals of 0.08 m. As shown in FIG. 2, five places are provided parallel to the front-rear direction, which is the blood circulation direction.

  Although the embodiments and examples of the present invention have been described above, the scope of the present invention is not limited thereto. For example, by changing the size of the air seat and the bottom of the seat or the size of the coupling body according to the seat width, seat depth, and knee length, various types of chairs and air for carrying according to the user A seat-type legrest can be widely used.

It is a specific use example figure of the air-seat type legrest for carrying of this invention. It is a perspective view at the time of the state which the air-seat type legrest for carrying of this invention inflated. It is a view from the upper part of the air-seat type legrest for carrying of this invention. It is a longitudinal cross-sectional view in the connection body position connected between the upper and lower sheet | seat inner walls of the air sheet | seat type legrest for carrying of this invention.
