Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a mannequin used for performance testing of vehicle seats.

(Prior art) Conventional mannequins of this type include, for example.
There is something like the one shown in Figure 5 described in SAE, PAPER, 720006. This mannequin is equipped with a skeletal frame 31 that constitutes the buttocks and thighs, and the back 33 and legs 35 are supported by the skeletal frame 31. The skeleton frame 31 is
For example, it is molded from hard resin, and its vertical cross-section in the left-right direction is as shown in FIG. Therefore, such a structure allows the mannequin to simulate the human body and improves suitability for performance testing.

(Problems to be Solved by the Invention) By the way, if the skeleton frame 31 is integrally constructed of hard resin as in the past, the body pressure of the buttocks and thighs when sitting on the seat is
1. The pressure pattern on the lower surface (indicating the magnitude of pressure in contour lines) is as shown in FIG. On the other hand, the actual pressure pattern of the human body is as shown in FIG. 8. Comparing the pattern of FIG. 7 with this FIG. 8, it can be seen that the pressure on both sides A is higher. This is because in the human body, the muscles flex at the sides of the buttocks and thighs, so a concentrated increase in pressure does not occur, whereas in the mannequin, the skeletal frame 31, which is integrally made of hard resin, This is thought to be because it does not bend. For this reason,
The conventional mannequin described above has a problem in that it cannot accurately simulate the body pressure of the buttocks and thighs of a human body.

Therefore, the object of this invention is to provide a mannequin that can improve the simulation of body pressure at the buttocks and thighs of the human body.

(Means for Solving the Problem) In order to achieve the above object, this invention includes a skeletal frame that constitutes the buttocks and thighs, and the side portions of this skeletal frame are configured to be more flexible than the central portion.

(Function) When the mannequin is seated, the sides of the flexible skeletal frame flex in the same way as the muscles of the human body flex.

(Example) An embodiment of this invention will be described below.

FIG. 1 shows an exploded perspective view of a skeletal frame 1 constituting the buttocks and thighs of a mannequin, and FIG. 2 shows a longitudinal sectional view of the skeletal frame in the left-right direction.

The skeleton frame 1 consists of a frame body 3 and a pad 5 fixed to the lower surface of the frame body 3 with an adhesive or the like. The frame main body 3 has a central portion 7 molded from a hard resin, and side portions 9, 10 and a rear side portion 11 made of a soft resin or the like, and are integrally constructed. The left and right side parts 9 and 10 with respect to the center part 7 may be integrally molded or may be separate pieces joined together with an adhesive or the like. A protruding reinforcing part 13 is provided at the center of the frame body 3, to which the back part is attached. The height H of the frame body 3 is determined in consideration of the thickness of the pad 5, and the height H of the entire skeleton frame 1 is approximately the same as that shown in FIG. 6.

The pad 5 is soft and has properties similar to the muscles of the human body, such that when pushed, it slides away.

A back portion and leg portions are attached to the skeleton frame 1 constructed in this way, as in the case of FIG. 5.

Next, the operation of the above embodiment will be described.

When a mannequin equipped with the skeletal frame 1 shown in FIG. 1 is seated on a seat, the soft pad 5 is bent as a whole due to a reaction force acting on the skeletal frame 1 from the seat side. This deflection is received by the frame body 3, but since the center part 7 is hard, the pressure acting on the pad 5 is not released.
Since the left side part 9, right side part 10, and rear side part 11 are soft, they easily bend like the muscles of the human body.
Pressure escapes to the side of pad 5. When the pressure was measured for the entire skeleton frame 1, it was as shown in Fig. 3. As can be seen from the pressure pattern in FIG. 3, there is no concentrated increase in pressure in region B corresponding to the side of the skeleton frame 1 as shown in region A in FIG. The pressure pattern shown is close to the actual pressure pattern in the human body. Therefore, the simulation of body pressure at the buttocks and thighs of the human body can be significantly improved.

Further, in this embodiment, since a soft pad 5 is attached to the lower surface of the frame body 3, the pad 5 serves as a cushioning material when the mannequin is seated on a hard chair or the like. Furthermore, since the periphery of the skeletal frame 1 is soft, even if it hits another object, the skeletal frame 1 itself will not be damaged and the object can be protected.

FIG. 4 shows another embodiment of this invention. In this embodiment, the entire frame body 15 is molded from, for example, hard resin, and slits 21 are provided in the left side 17 and right side 19, respectively.
19 is made easier to bend. The other configurations are the same as those of the embodiment shown in FIG. 1, so the same reference numerals are given and the explanation will be omitted.

This embodiment also provides the same effects as the above-mentioned embodiment, and the entire frame body 3 can be molded from a uniform material, making it easy to manufacture.

Note that this invention is not limited to the above-mentioned embodiment. For example, frame body 3, 15
It is also possible to construct the whole body by molding it with a soft material and reinforcing the central part with a hard material. The pads 5 do not necessarily need to be provided, and the frame frame 1 is made up of only the frame bodies 3 and 15, and the center part 7 is softly molded like the side parts 9 and 10, or the side parts 17 and 19 are formed into a soft shape. It is also possible to provide a configuration in which the slit 21 is provided. The frame bodies 3 and 15 may be made of a hard material, and the pad 5 may be configured such that the side portions are softer than the center portion. In the embodiment shown in FIG. 4, instead of providing the slit 21, the left and right side parts 17, 19 can be formed thinner to make them easier to bend. Further, the entire frame body 15 can be made of an elastic material.

(Effect) As is clear from the above, according to this invention, the sides of the skeletal frame flex in the same way as the muscles of the human body, so the pressure pattern of the skeletal frame relative to the pressure pattern of the buttocks and thighs of the human body The simulation can be significantly improved, making it possible to perform more accurate performance tests on vehicle seats and the like.
