Abstract

PROBLEM TO BE SOLVED: To improve the workability of a storage device for an automobile collision testing dummy without changing the shape of the neck, lumbar vertebra and buttocks of the dummy stored for a long time. SOLUTION: A storage device is basically formed with a chair type frame 1. Threaded L-shape fittings 2, 3 are mounted on the frame 1 to support both sides of a dummy 6. The waist of the dummy 6 is supported by inserting fittings 8, 9 therein. Both planta pedises are put on the bar 12 of the frame 1. The top of the head is supported by a fitting 13 inserted in the upper part of the frame 1. By removing the fitting 13, work for assembling a sensor into an occipital region is easily done. The frame 1 at a dorsum part is open to allow easy work for assembling the sensor through the back as it is without replacing it to a working table. Disassembling/assembling work can be done as it is without replacing it onto the working table.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage device for storing an automobile crash test dummy.

[0002]

2. Description of the Related Art Conventionally, when storing a dummy for an automobile crash test, the dummy is conventionally seated on a general chair or a chair dedicated to the dummy, the upper body leans against a backrest, and a head is placed on an iron pole standing in front of the dummy. The dummy was kept by fixing the part.

[0003]

However, such a conventional storage method has the following problems. (A) Since the material of the dummy is urethane foam, if it is seated for a long time, the buttocks (buttocks) become flat due to the weight of the dummy itself. The lumbar spine is 12 cm in diameter and is made of curved rubber, which holds the upper body alone and deforms, affecting the characteristics. Similar concerns arise for the neck because it is made of rubber. Crash tests associated with the development of new vehicles require very sophisticated academic data analysis. For this purpose, the dummy itself is also stipulated in US federal regulations and is treated as a precision instrument, and is regularly tested.
This verification test also defines the external dimensions, and if the shape or characteristics change, the verification will not be passed. In Japan, the above certification and dummy mounting method are specified in the "Technical Standards for Crew Protection in Frontal Collisions" established by the Ministry of Transport. Here, the vertical and horizontal distance from the center of the accelerator pedal surface of the vehicle when the dummy is mounted on the collision test vehicle to the hip point designed for the dummy is also specified. Therefore, if the buttocks are flat, an error occurs between the actual hip point and the designed hip point. Such errors and changes in the characteristics of the neck and lumbar spine affect the data obtained during the crash test. This makes the dummy unusable.

(B) Due to the presence of the backrest and the iron column for fixing the head, it is not easy to incorporate sensors into the head, chest, and waist, and it is necessary to replace the work table. The weight of one dummy is about 70 kg, which requires a great deal of labor.

[0005] (c) It is necessary to change the transportation to the place of use on a trolley.

SUMMARY OF THE INVENTION The present invention has been made to solve these drawbacks, and has no change in the shape of each part of the dummy even after long-term storage, thereby improving workability. The purpose is to provide.

[0007]

According to the present invention, there is provided a storage device for a vehicle crash test dummy, comprising:
The dummy is held at several places so that weight is not applied to the lumbar spine and buttocks.

In a preferred aspect of the present invention, the dummy for an automobile crash test is held at the head, underarms, waist, right and left, and soles.

[0009] In these storage devices, it is desirable that a portion corresponding to a backrest is opened in order to facilitate the incorporation of the sensor into the chest, the waist, and the like.

The head holding member with an angle adjusting function may be detachably attached. It is also conceivable to attach a caster to the lower part.

According to the present invention, the dummy is held by the dummy's head, armpits, waist, left and right, soles, etc., so that the dummy's neck, lumbar spine, and buttocks are not weighted. There is no change in the shape of each part of the dummy even after storage, and disassembly and assembly work can be performed while sitting on the storage chair, eliminating the need for a work table.

[0012]

FIG. 1 is a front view showing a dummy storage chair according to an embodiment of the present invention, FIG. 2 is a side view thereof, and FIG. It is a side view. The basic structure of this chair is a frame 1 configured as a chair. L on top of frame 1
The metal molds 2 and 3 are fixed, and rubbers 4 and 5 are attached to the horizontal protruding portions, for example, and both sides of the dummy 6 are supported at this portion. The metal fittings 2 and 3 are cut with screws, and are fixed to the upper portion of the frame 1 from above and below with nuts. As a result, the height of both sides of the dummy can be adjusted, the weight of the dummy 6 hanging on the lumbar vertebra can be adjusted, and a well-balanced sitting posture can be obtained.

The waist of the dummy 6 is supported by inserting metal fittings 8 and 9 into square holes 7 located at the right and left positions of both waists of the dummy 6. The metal fittings 8 and 9 are attached to the lower part of the backrest of the frame 1.
Iron plate 10 with U-shaped notch that can set 9
11 is attached, the metal fittings 8 and 9 are dropped into the U-shaped groove, and fixed with the lock lever. Both soles of the dummy 6 are placed on the bar 12 in front of the frame 1. The head fixing bracket 13 is
The two positions A and B are screwed to adjust the angle, and when inserting the round bar 15 at the tip of the metal fitting 13 into the hole 14 at the top of the dummy 6 head, the position and angle of the hole 14 are accurately adjusted. Can be fixed together.

At the time of work such as mounting a sensor on the back of the head, the metal fitting 13 is removed from the frame 1 and the top of the head to facilitate the work. In addition, since the frame 1 at the back is open, it is possible to perform operations such as mounting a sensor while the dummy 6 is sitting on the chair. Since casters 16 are provided at the lower four corners of frame 1, dummy 6
It is easy to move while sitting.

[0015]

As described above, according to the present invention, the shape of the neck, lumbar spine, and buttocks is changed because the weight of the dummy is supported by the head, both sides, both hips, and both soles, and the dummy is not directly seated. And the conventional disadvantages can be solved. As a result, it is possible to eliminate a large waste of making an unusable dummy merely by storing an expensive dummy of about 4 million yen per body, thereby reducing costs. Also, you can work while sitting on this chair without replacing it on the work table, reducing labor,
Work efficiency can be improved and space can be effectively used.
