Description

[Detailed description of the invention] (Field of industrial application) 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. FIG. 5 shows cross-sections of the upper body with the head omitted and the lower body with the lower legs omitted, showing a frame 101 constituting the buttocks, a lumbar block 103 constituting the lumbar vertebrae, and a back constituting the back. block 105, each block 1
03 and 105 are connected at each joint support portion 107 via a spine joint 109. Each of these spine joints 107 is configured to be rotatable at its intermediate portion, and is positioned corresponding to the points on the human spine shown in FIG. 6, so as to simulate the human body.

(Problem that the invention attempts to solve) By the way, in the above structure, each spine joint 1
09 is fixed to each joint support portion 107. Therefore, if the human body is limited to that shown in FIG. 6, the conventional mannequin described above can closely simulate the human body. However, the human body cannot necessarily be limited to the one shown in FIG. 6 because of differences in skeletal structure between people and differences in the degree of curvature of the spine due to movement of the person's center of gravity in response to changes in posture. Therefore, in order to simulate the human body with a mannequin according to these differences, it is necessary to prepare multiple types of mannequins with different fixed positions of the spine joints for each difference, which makes management extremely complicated, This is extremely disadvantageous in terms of cost.

Therefore, the object of this invention is to provide a mannequin that can closely simulate the human body without having to prepare multiple types, regardless of the differences in skeletal structure between people.

(Means for Solving the Problems) In order to solve the above problems, this invention consists of a frame constituting the buttocks, a lumbar block constituting the lumbar region, a back block constituting the back region, and each of these blocks. A mannequin equipped with a spinal joint that connects the spine, a spring that constitutes a flexor-extensor muscle, and a weight adapted to the human weight, wherein the spinal joint is configured to be movable, and a lock that positions the spinal joint at a predetermined movement position is provided. The configuration is such that a means is provided.

(Function) The spinal joint can be moved and positioned at a predetermined movement position by the locking means.

(Example) One example of this invention is described below.

FIG. 1 is a longitudinal sectional view of a mannequin according to an embodiment of the invention, and FIG. 2 is a perspective view thereof. This mannequin has a lower body 1 with the lower legs omitted and an upper body 3 with the head omitted.

The lower body 1 includes a frame 5 that constitutes the buttocks, and a thigh frame 7 that constitutes the thighs is integrally constructed with this frame 5.

The upper body 3 has a lumbar block 9 forming a lumbar region and a back block 11 forming a back region.

Three lumbar blocks 9 of the same size are provided, and one back block 11 is provided which is larger than these lumbar blocks 9. A joint support part 13 protruding forward (to the left in FIG. 1) is fixed to each lumbar block 9, and a joint support part 15 is fixed to the back block 11.
is fixed. These joint supports 1
A spine joint 17 is supported between 3 and 15,
Each lumbar block 9 and back block 11 are connected to each other.

These spine joints 17 are constructed as shown in FIGS. 3 and 4, and the joint support parts 13, 1
It is possible to move forward and backward along line 5. In other words, the spine joint 17 is the joint attupa 19.
and a joint floor 21, and a joint shaft 23 passing through the joint top 19 and the joint floor 21 from side to side allows them to be relatively rotatably connected. Double nuts 27 are fastened to the left and right sides of the joint shaft 23 via washers 25 to prevent the joint shaft 23 from coming off.

Further, a screw pin 29 is provided protruding from the joint upper 19 and the joint lower 21,
A slide lock ring 30 is screwed onto this screw pin 29, and a joint slide 31 is integrally molded at the tip. On the other hand, a slide guide 33 is formed in the joint support parts 13 and 15, and the joint slide 31 is fitted therein. Therefore, the spine joint 17 is movable and the slide lock ring 3
0 to the joint supports 13 and 15, the spinal joint 17 can be positioned, and the screw pin 29 and slide lock ring 30 constitute locking means.

The lowermost joint support part 13 is attached to the frame 5 at a hip point joint 34.
are connected via.

At the tips of the joint support parts 13 and 15,
A spring 35, which constitutes a flexor/extensor muscle, is attached.
This spring 35 is composed of three compression springs 37 and two tension springs 39. The compression spring 37 is interposed between the spring receivers 41 of each joint supporter 13 and 15, and each spring receiver 41 is connected to each joint supporter 13 and 15 by a bolt nut 43.
It is fixed at 15.

The tension spring 39 is arranged on both the left and right sides of the compression spring 37 and is supported by spring receiving pins 45 and 47 fixed to the uppermost joint support part 15 and the lowermost joint support part 17.

A weight support section 48 is further fixed to the back block 11, and a weight 51 is attached to this weight support section 48 via an arm 49. The weight of this weight 51 is determined to match the human weight in the fully assembled state.

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

When moving the spine joint 17, first,
The slide lock ring 30 is rotated to release the fastening from the joint supports 13 and 15. Then, the joint slide 31 moves to the slide guide 3.
Movement is free within 3. Incidentally, if a knurling or the like is provided around the slide lock ring 30, the operation will be facilitated. And spine joint 17
is moved back and forth (in the direction of arrow A in FIGS. 1 and 4) along the joint supports 13 and 15, and at a predetermined movement position, the slide lock ring 30 is rotated in the opposite direction and fastened. Spinal joint 1 in this position
7 is locked from forward and backward movement along the joint supports 13 and 15, and positioning is performed.

In this way, by moving and positioning each spinal joint 17 to an arbitrary position with a simple operation by rotating the slide lock ring 30, each spinal joint 17 can be moved to the point shown in FIG.
It can be adjusted to In addition, due to differences in skeletal structure between people and differences in the degree of curvature of the spine due to the shift of the human center of gravity in response to changes in posture, points
Even if a difference occurs, the position of the spinal joint 17 can be adjusted according to this difference, and the human body can be well simulated regardless of the difference.
Therefore, performance tests of vehicle seats and the like can be conducted appropriately.

Further, since the above-mentioned differences are dealt with by adjusting the spine joint 1, there is no need to prepare multiple types of mannequins for each difference, which makes management extremely simple and extremely advantageous in terms of cost.

Furthermore, if each joint 17 no longer operates smoothly due to repeated use, it can be easily replaced by loosening the slide lock ring 30, moving each joint 17, and removing it from the distal end side of the joint supports 13, 15. I can do it.

It goes without saying that the mannequin set as described above can be rotated back and forth at each of the joints 17 and 34.

(Effects) As is clear from the above, according to the configuration of this invention, it is possible to move and position the spinal joint, so there are differences in the skeletal structure of different people and differences in the degree of curvature of the spine due to the shift of the human center of gravity in response to changes in posture. Regardless of the situation, the human body can be well simulated. Furthermore, since each difference is accommodated by adjusting the movement of each spine joint, there is no need to prepare multiple types of mannequins, which makes management extremely simple and extremely cost-effective.
