Omni-directional shoulder assembly for crash test dummy

1. A shoulder assembly for a crash test dummy comprising:

a movable clavicle adapted for attachment to a spine of the crash test dummy for freedom of movement in three-dimensional space;

a scapula adapted to be non-rigidly mounted to the spine for freedom of movement in three-dimensional space;

a shoulder cup member adapted for attachment to the spine in a plurality of axes for a shoulder joint;

an upper arm assembly having an arm bone made of a plastic material and having a ball at one end for connection to said shoulder cup member to allow an impact on the shoulder joint of the dummy to move the shoulder assembly towards the spine, said ball includes a slot therein to allow said bone to rotate; and

a first threaded fastener on said ball and being disposed in one end of said shoulder cup member and threadably engaging said shoulder cup member, said first threaded fastener having a threaded hole, and a second threaded fastener extending through an opposite end of said shoulder cup member and threadably engaging said threaded hole of said first threaded fastener to keep said threaded first fastener from backing out when said upper arm assembly rotates.

2. A shoulder assembly as set forth in claim 1 wherein said ball has an inner portion made of a metal material and an outer portion made of an elastomeric material disposed about an outer surface of said inner portion.

3. A shoulder assembly as set forth in claim 2 wherein said outer portion of said ball includes said slot therein.

4. A shoulder assembly as set forth in claim 1 including at least one mounting member adapted to be disposed between said scapula and the spine.

5. A shoulder assembly as set forth in claim 4 wherein said at least one mounting member is made of an elastomeric material.

6. A shoulder assembly as set forth in claim 1 including at least one mounting member connected to said clavicle.

7. A shoulder assembly as set forth in claim 6 wherein said at least one mounting member is made of an elastomeric material.

8. A crash test dummy comprising:

a body;

a spine assembly operatively attached to said body; and

a shoulder assembly operatively attached to said spine assembly and comprising a movable clavicle attached to said spine assembly for freedom of movement in three-dimensional space, a scapula non-rigidly mounted to said spine assembly for freedom of movement in three-dimensional space, a shoulder cup member attached to said spine assembly in a plurality of axes for a shoulder joint, and an upper arm assembly having an arm bone made of a plastic material and having a ball at one end for connection to said shoulder cup member to allow an impact on the shoulder joint of the dummy to move the shoulder assembly towards said spine assembly, said ball includes a slot therein to allow said bone to rotate; and

a first threaded fastener inside of said ball and being disposed in one end of said shoulder cup member and threadably engaging said shoulder cup member, said first threaded fastener having a threaded hole, and a second threaded fastener extending through an opposite end of said shoulder cup member and threadably engaging said threaded hole of said first threaded fastener to keep said first threaded fastener from backing out when said upper arm assembly rotates.

9. A crash test dummy as set forth in claim 8 wherein said ball has an inner portion made of a metal material and an outer portion made of an elastomeric material disposed about an outer surface of said inner portion.

10. A crash test dummy as set forth in claim 9 wherein said outer portion of said ball includes said slot therein.

11. A crash test dummy as set forth in claim 8 including at least one mounting member disposed between said scapula and said spine assembly.

12. A crash test dummy as set forth in claim 11 wherein said at least one mounting member is made of an elastomeric material.

13. A crash test dummy as set forth in claim 8 including at least one mounting member connected to said clavicle.

14. A crash test dummy as set forth in claim 13 wherein said at least one mounting member is made of an elastomeric material.
