Positioning table assembly for crash test dummy

1. A positioning table assembly for a crash test dummy comprising:

a table bed adapted to be attached to an impact table for the crash test dummy;

a table top adapted to support the crash test dummy and movably attached to said table bed for independent linear movement in X and Y axes and rotationally about a Z axis to position the crash test dummy relative to said table bed; and

wherein said table bed includes a plurality of rails and a plurality of bearing carriages attached to said table top and movable along said rails to allow said table top to move linearly along said rails and relative to said table bed.

2. A positioning table assembly as set forth in claim 1 wherein said table top includes a bearing plate and a top plate moveable relative to said bearing plate.

3. A positioning table assembly as set forth in claim 2 wherein said table top includes a plurality of ball transfers disposed between said bearing plate and said top plate to allow said top plate to be moved in an X and Y direction and rotate about the Z axis relative to said bearing plate.

4. A positioning table assembly as set forth in claim 2 including a plurality of electromagnets to hold said top plate top securely to said bearing plate when not engaged.

5. A positioning table assembly as set forth in claim 2 wherein said top plate includes a lip extending toward said bearing plate.

6. A positioning table assembly as set forth in claim 1 wherein said table bed includes a frame having a plurality of legs extending downwardly.

7. A positioning table assembly as set forth in claim 6 wherein said table bed includes a plurality of casters connected to said legs to allow said table bed to move along a support surface.

8. A positioning table assembly as set forth in claim 6 including a plurality of clamp assemblies adapted to attach said frame to the impact table.

9. A positioning table assembly as set forth in claim 8 wherein said clamp assemblies are adjustable.

10. A positioning table assembly as set forth in claim 8 wherein each of said clamp assemblies include a hook member being generally “j” shaped.

11. A positioning table assembly for a crash test dummy comprising:

a table bed adapted to be attached to an impact table for the crash test dummy;

a table top adapted to support the crash test dummy and movably attached to said table bed for independent movement in X and Y axes and rotationally about a Z axis to position the crash test dummy relative to said table bed;

said table top including a bearing plate and a top plate moveable relative to said bearing plate;

a plurality of electromagnets to hold said top plate top securely to said bearing plate when not engaged; and

a plurality of solenoids surrounding said electromagnets to allow said electromagnets to drop out of the way when the crash test dummy is being positioned.

12. A positioning table assembly for a crash test dummy comprising:

a table bed adapted to be attached to an impact table for the crash test dummy, said table bed including a frame and a plurality of rails extending linearly along said frame;

a plurality of bearing carriages movable along said rails for linear movement along said rails; and

a table top having a bearing plate attached to said bearing carriages, a top plate adapted to support the crash test dummy, and a plurality of ball transfers disposed between said top plate and said bearing plate for independent linear movement in X and Y axes and rotationally about a Z axis to position the crash test dummy relative to said table bed.

13. A positioning table assembly as set forth in claim 12 including a plurality of electromagnets to hold said top plate top securely to said bearing plate when not engaged.

14. A positioning table assembly as set forth in claim 12 wherein said top plate includes a lip extending toward said bearing plate.

15. A positioning table assembly as set forth in claim 12 including a plurality of casters connected to said frame to allow said table bed to move along a support surface.

16. A positioning table assembly as set forth in claim 12 including a plurality of clamp assemblies adapted to attach said frame to the impact table.

17. A positioning table assembly as set forth in claim 16 wherein each of said clamp assemblies include a hook member being generally “j” shaped.

18. A positioning table assembly for a crash test dummy comprising:

a table bed adapted to be attached to an impact table for the crash test dummy, said table bed including a frame and a plurality of rails extending linearly along said frame;

a plurality of bearing carriages cooperating with said rails for movement along said rails;

a table top having a bearing plate attached to said bearing carriages, a top plate adapted to support the crash test dummy, and a plurality of ball transfers disposed between said top plate and said bearing plate for independent movement in X and Y axes and rotationally about a Z axis to position the crash test dummy relative to said table bed;

a plurality of electromagnets to hold said top plate top securely to said bearing plate when not engaged; and

a plurality of solenoids surrounding said electromagnets to allow said electromagnets to drop out of the way when the crash test dummy is being positioned.
