Coupling design for abdomen flesh of anthropomorphic test device
An anthropomorphic test device includes an abdomen component, a base member, and a resilient flange coupled to and extending from the base member. The base member has opposing inner and outer surfaces and peripheral edge, with the inner surface defining a first cavity. The resilient flange includes opposing flange inner and outer surfaces and a connecting flange peripheral edge surface, with the flange inner surface defining a second cavity and with the second cavity extending from and open with the first cavity. The abdomen component is partially contained within the first and second cavity and coupled to the pelvis and resilient flange such that a first portion of an outer surface of the abdomen component is engaged with the inner surface of the base member and such that a second portion of the outer surface of the abdomen component received is resiliently retained by the resilient flange.

3. The anthropomorphic test device of claim 1 , wherein a maximum width of said flange is greater than said first width.
4. The anthropomorphic test device of claim 1 , wherein said peripheral edge of said resilient flange defines an opening, and wherein said abdomen component is at least partially received through said opening and into said first and second cavity when said abdomen component is coupled to said base member and said resilient flange.
5. The anthropomorphic test device of claim 1 , wherein said abdomen component is hollow and defines an internal cavity, and wherein said abdomen component includes a first support member disposed within said internal cavity.
6. The anthropomorphic test device of claim 5 , wherein said base member includes a second support member disposed within said first cavity, and wherein said second support member is disposed adjacent to said first support member when said abdomen component is coupled to said base member.
7. The anthropomorphic test device of claim 1 , wherein said base member comprises an inner foam core covered with a first skin, and wherein said resilient flange comprises a second skin, and wherein said second skin is coupled to and extends from said first skin.
8. The anthropomorphic test device of claim 7 , wherein said second skin is integrally formed with and extends from said first skin.
9. The anthropomorphic test device of claim 7 , wherein a thickness of said second skin ranges from 3 to 5 millimeters.
10. The anthropomorphic test device of claim 7 , wherein said second skin defines a looped structure with said looped structure including an outer loop portion and an inner looped portion and a transitional loop portion connecting said outer and inner looped portions, and with each of said outer and inner looped portions separately coupled to and extending from said first skin.
11. The anthropomorphic test device of claim 10 , wherein said second skin defines a loop cavity within said looped structure, and wherein said first skin defines a foam-containing cavity in open communication with said loop cavity, and wherein said inner foam core is entirely contained within said foam-containing cavity.
12. The anthropomorphic test device of claim 1 , wherein a length of said resilient flange extending from said base member is equal to a corresponding height of said second portion extending from said first portion.
13. The anthropomorphic test device of claim 1 , wherein a bottom of said first portion of said abdomen component includes one or more projection regions, and wherein said base inner surface defines one or more surface depressions, and wherein one of said one or more projection regions is seated within a corresponding one of said one or more surface depressions when said abdomen component is coupled to said base member.
14. The anthropomorphic test device of claim 1 , wherein said abdomen component further includes a transversely extending notch connecting an upper portion of said abdomen component to said second portion, and wherein said flange peripheral edge abuts said notch when said abdomen component is coupled to said base member and said resilient flange.
15. A method of forming a portion of an anthropomorphic test device including a base member having a base inner surface defining a first cavity and an abdomen component having a first portion defining a first width and a second portion defining a second width larger than the first width, said method comprising:
coupling a resilient flange to said base member, the resilient flange having a flange inner surface, an opposing flange outer surface, and a flange peripheral edge surface with the flange defining a second cavity and with the second cavity extending from and open with the first cavity; and
coupling the abdomen component to the base member and the resilient flange such that the abdomen component is partially contained within the first and second cavity and such that an outer surface of the first portion of the abdomen component is engaged with the base inner surface and such that an outer surface of the second portion of the abdomen component is resiliently retained by the resilient flange.
16. The method of claim 15 , wherein an at-rest maximum width of the flange is less than the second width and wherein the at-rest maximum width of the flange is greater than the first width, and wherein said step of coupling the abdomen component to the base member and the resilient flange further comprises:
applying force from the second portion of the abdomen component to the flange in a direction towards the flange outer surface during the step of coupling the abdomen component to the base member and the resilient flange to increase the width of the flange to a value greater than the at-rest maximum width and greater than the second width.
17. The method of claim 15 , wherein the abdomen component is hollow and defines an internal cavity, and wherein said method further comprises the steps of:
disposing a first support member within said internal cavity;
disposing a second support member within said first cavity; and
disposing the second support member adjacent to the first support member when the abdomen component is coupled to the base member.
18. The method of claim 15 , wherein a bottom of the first portion of said abdomen component includes one or more projection regions, and wherein the base inner surface defines one or more surface depressions, and wherein one of the one or more projection regions is seated within a corresponding one of said one or more surface depressions during said step of coupling the abdomen component to the base member and the resilient flange.
