Description

a .Mum han: 511 367 10 15 20 25 30 35 A special purpose is to provide an aid for following up personal injuries that have occurred in a vehicle in a traffic accident.

A special purpose is to designate a doll which is suitable for such follow-up.

These and other objects, which will appear from the following description, have now been achieved by means of a human-sized doll having the features set forth in claim 1. Advantageous embodiments are set out in the dependent claims.

This has created a doll, which can be converted to correspond to the body size of different people who have traveled in an accident vehicle. Because the doll is also adjustable in different body positions, each person's body position can be recreated at the time of the accident. Thus, one can easily and reliably deduce where different body parts hit different interior details in the vehicle in the traffic accident. The invention now provides the opportunity to evaluate the crash safety of cars based on real accidents.

According to one way of looking at the invention, it lies in a doll having the contours of a human skeleton, is formed of a number of articulated, elongated segments with a small cross-sectional area relative to human body dimensions and is variable in body size and posture. Preferably, all joints have the same degrees of freedom as the corresponding joints in a human being.

In a preferred embodiment of the doll, its extremities comprise an inner and an outer elongate portion, which are hingedly connected to each other. Each of the portions comprises an inner part and an outer part, which are displaceable in relation to each other in the longitudinal direction and fixable in different mutual positions.

This achieves a simple adjustability of the length of the extremities at the same time as these can be moved to corresponding positions such as human arms and legs. Particularly preferred is that the inner part and the outer part are steplessly adjustable relative to each other.

It is preferred that the doll has a backbone that comprises several segments connected to each other and fixed in a fixable manner. In this way, one can in a realistic way imitate human postures. It is particularly advantageous to design these segments so that the length of the spine can be changed by adding, removing or replacing such segments.

In a preferred embodiment, the doll has a shoulder portion and a hip portion, to which the extremities are connected. The connection points of the extremities are displaceable laterally in relation to the dorsal spine for setting the width dimensions, which in a simple way provides a good adjustability for imitation of different body dimensions.

In the following, the invention will be described in more detail with reference to a preferred embodiment.

Fig. 1 shows a doll according to a preferred embodiment in perspective view obliquely from the front.

Fig. 2 shows the doll in perspective view obliquely from behind.

Fig. 3 shows the hip portion of the doll in more detail.

Fig. 4 shows in more detail the lower extremities of the doll and its length adjustment.

The doll shown in Figs. 1 and 2 comprises a torso portion 10 with upper and lower extremities connected thereto, i.e. arms 40 and legs 50. The torso portion 10 comprises a spine 11 which in turn consists of a plurality of backbone segments 12 placed one after the other These look the same and have a female end and a male end, respectively, which are articulated together by means of bolts 33 and wing nuts 34 to form hinge joints. The spinal segments are preferably available in different lengths. The length of the spine 11 can then be easily adjusted by removing, adding or replacing one or more spinal segments 12. The spinal segments 12, which are shown more clearly in Fig. 3, have at their lower end, here the female end, at the front edge a circular arc with center in the bolt 33 and at the rear edge a new:: m. .lçäiw mi .. ... . . H1 ... inl I ii .ni Ü ml. . i. I ii Eli '511567 14 corner to form a downward, rear abutment surface.

The spine 11 can thus be bent forwards but only to a limited extent backwards, as can a human spine.

The spine normally describes both swaying and kyphosis. The torso portion 10 further comprises a shaft portion 13, which is located at the upper portion of the spine 12. The shaft portion 13 is elongate and comprises an inner shaft portion 14, which is rigidly connected to and extends laterally in both directions out of the upper portion of the spine 12, more specifically, the shaft portion extends out of a coupling segment 3, which constitutes the the second uppermost segment of the spine 11. On each side of the inner shaft portion 14 is attached a respective outer shaft portion 15. The inner shaft portion 14 and the two outer shaft portions 15 are connected to each other by a longitudinal sliding mechanism 30, comprising one in each of the the inner shaft portion 14 and the outer shaft portion 15 provided an elongate hole 31, which extends laterally along the shaft portion 13 and is formed as an elongate, through-opening, and two screw members 32 located in the respective holes. Each of the screw members comprises a carriage bolt 33 and a wing nut 34. By loosening the respective wing nuts 34, the longitudinal sliding mechanism 30 is released and the respective outer shaft portion 15 can be displaced relative to ll the inner shoulder portion 14 so as to change the shoulder width of the doll. In addition, on the outer shaft portions there is each a ball joint 35. Via these ball joints the two arms 40 are connected to the shaft portion 13. Because the arms 40 are connected to the shaft portion 13 via ball joints 35, the plurality of human arm positions can be imitated.

At its lower end, the spine 11 is connected to a hip portion 16, which comprises a transversely extending transverse adjusting member 17 and two leg attachment members 18. The hip portion and its adjusting possibilities are more clearly illustrated in Fig. 3. The transverse adjusting member 17 is elongate and extends parallel to the shoulder portion 13 in the lateral direction out on the respective sides of the spine 11. The upper side of the transverse adjusting member facing the spine 11 is adapted to enable weights to be placed thereon to give the doll an increased weight and an associated depression of a vehicle seat corresponding to a person to be imitated. In the transverse adjusting means 17 there is on each side of the spine 11 a longitudinal groove 31. 18 extends downwards from the transverse adjusting means 17 in the two leg fastening means direction away from the spine 11 on each side thereof. The leg fasteners 18 are each connected to the groove 31 of the transverse adjusting member 17 via two screw members 32 in a manner similar to the shaft portion 13. At the end of the respective leg fasteners 18 facing away from the spine 11, the legs 50 are fixed in each ball joint 35. The attachment of the legs 50 via ball joints 35 allows, as with the arms, the adjustment of human leg positions. In addition, thanks to the ball joints, the legs 50 when transporting the doll can be directed upwards along the torso portion 10, parallel to the arms, which makes the doll easy to handle, easy to carry and takes up little space in the transport position.

Extending from the front side 13 of the shoulder portion is a thoracic member 19. This comprises a holding member 20 extending forwards from the segment 3 of the spine 11, a central portion 21 is hingedly attached to the holding member 20, in the form of a downwardly directed, elongate element. From the central portion 21, on each side, four rib members 22 extend perpendicularly outwards in the lateral direction. Each of the rib members 22 is formed by a flexible wire member, which comprises continuous wire and a number of segments placed one behind the other. The wire member can be bent to the desired shape and has sufficient rigidity to maintain a shape thus given. In this way, the diagonal path of the belt over the chest can be recreated, and rib fractures can be illustrated in a simple and clear way.

On top of the shoulder portion and in continuation of the spine 11, a head 25 is articulated arranged via a neck segment 24 and four wire members 5 of the type described above. The wire members are each attached to a separate bottom segment of the head 25 and hingedly connected to the head 25 along it (not shown). ). The four bottom segments are flat bottom edge 6. Thanks to the wire members 5 and their attachment, the head can be bent in different directions as well as brought into a translational movement. The height of the top segment can be varied by replacement, and the length of the wire members can be varied.

Each of the arms 40 comprises an upper arm 41 and a forearm 44, which are hingedly connected to each other via a hinge joint 36, which comprises a male and a female end, which are pivotally connected via a screw member 32, in a manner corresponding to the the upper spine segments 12 described above. The upper arm 41 comprises an inner part 42, which is connected via the ball joint 35 to the shaft portion 13, part 43, the iron joint 36. and an outer part which is connected to the forearm 44 via the inner and outer part 42 and 43 are connected to each other via a longitudinal sliding mechanism 30 in a manner similar to that described above in connection with the shaft portion 13. The forearm 44 also comprises an inner part 45, which is connected to the upper arm 41, and an outer part 46, the inner part and outer part 45 of the arm , which are connected to a hand 47. The sub-46s are also displaceable relative to each other by means of a longitudinal sliding mechanism 30.

The hand 47 is connected to the forearm 44 via a ball joint 35. Each hand comprises a rigid palm 48, from which flexible fingers 49 extend. The flexible fingers 49 are designed as the wire members described above, for example as the rib members 22. The hand 47 can be placed in human hand positions as well as being made to correspond to different fractures.

The two legs 50 are formed in a manner corresponding to the arms 40 and each consists of a thigh 51 and which are hingedly connected to each other. The thigh 51 consists of an inner part 52 and an outer part 53 which is connected to a lower leg 54, via a hinge joint 36, as well as at the arms. 10 20 25 30 35 7 5171 367 with each other via a longitudinal sliding mechanism 30, in the manner described above. The lower leg 54 also comprises an inner part 55 and outer part 56, the parts of the thigh 51.

A foot 57 is connected to the lower leg via a ball joint which is connected in the same way as 35. The foot 57 consists of a heel member 58 and from there forwardly extending flexible members 59 and two transversely extending, rigid members 60, through which they the flexible members 59 extend. The flexible members 59 consist of wire members in a manner corresponding to the fingers and rib members described above and correspond in structure to the foot bones and toes. As with the hands 47, different positions and fractures can be simulated.

The lower legs 54 and feet 57 are also shown in Fig. 4, which illustrates the longitudinal displaceability of the extremities. From Fig. 4 it is also clear how the hinge joints 36 have been given flexibility in accordance with human mobility by facing surfaces of the knee joints being curved to allow only bending in one direction, as described above in connection with the spinal segments 12.

On the spine 11 and on the thighs 51, measuring tape 7 is arranged to facilitate the adjustment of correct measurements.

Measuring tapes can advantageously be arranged with each longitudinal sliding mechanism. Other forms of measuring means or measuring aids arranged on the length-adjustable elements can also be used.

A major advantage of the doll according to the embodiment shown is that the different parts can be quickly and easily mounted apart at different places on the doll so that the doll can be placed even in severely deformed vehicles. In this case, various fractures, such as arm fractures and bone fractures, can also be recreated.

The doll according to the exemplary embodiment is designed in wood, but other rigid materials with low weight and good strength are also conceivable, such as plastic or metal. A great advantage of the doll is that it is made of interconnected segments, each of which is elongated and has a small cross-sectional area in relation to human dimensions 1 * ... 5 ... l 511 367 8 10. This makes the doll easy to handle and has low weight, while at the same time various anthropometrically correct, human body measurements can be recreated.

An important advantage of the described doll is that it is designed of a number of uniform and recurring components, such as slidable segments, hinge joints, ball joints and wire members.

Another advantage of the described doll is the square cross-section of the components. This creates flat surfaces on which you can mark and note. A special advantage is that the flat surface has such a structure that you can write directly on it.
