DESCRIZIONE DESCRIPTION
A corredo di una domanda di brevetto per invenzione industriale avente per titolo: In support of a patent application for industrial invention entitled:
?Collo artificiale articolato per testa di manichino?. ? Articulated artificial neck for mannequin head ?.
La presente invenzione propone un collo artificiale articolato per testa di manichino che possa essere utilizzato in manichini di corpo umano o solamente di testa umana durante test a differenti condizioni d?urto per studiare sperimentalmente aspetti di danneggiamento in situazioni meccaniche dovute a incedenti sull?uomo. The present invention proposes an articulated artificial neck for manikin head which can be used in mannequins of human body or only of human head during tests under different impact conditions to experimentally study aspects of damage in mechanical situations due to human accidents.
I danni sulla testa sono la risposta alle azioni applicate ed ad urti su di essa. Lo studio di tali situazioni ? in genere effettuato tramite modelli e manichini al fine di determinare la risposta della testa considerata generalmente insieme alla struttura del collo con architettura a limitata articolazione. Vi sono pochi dispostivi in uso che includono un collo artificiale di manichini per determinare sperimentalmente la risposta dinamica in situazioni di urto della testa con il contributo del collo. Damage to the head is the response to applied actions and impacts on it. The study of such situations? generally performed through models and mannequins in order to determine the head response generally considered together with the neck structure with limited articulation architecture. There are few devices in use that include an artificial mannequin neck to experimentally determine the dynamic response in head impact situations with the help of the neck.
Il brevetto US3753301 del 1973 presenta un manichino la cui testa ? collegata ad un collo con una articolazione meccanica ad un solo corpo dotata di smorzatore viscoso per due rotazioni ortogonali fra loro. Il brevetto US3877156 del 1975 presenta un manichino per prove d?urto con la testa articolata con una connessione che permette un limitato moto angolare solo nel piano sagittale. Nel brevetto US3916535 del 1975 si presenta una testa rigida di manichino con un collo rigido articolato con la testa tramite un giunto sferico. Il brevetto US9972220 del 2018 propone il segmento cervicale di colonna artificiale i cui moduli vertebrali sono realizzati da corpi rigidi che includono elementi flessibili. Nel brevetto CN203798525U si presenta un collo artificiale articolato con due segmenti vertebrali rigidi collegati da giunto sferico e connessi con due molle per simulare l?azione dei muscoli spinali. Il Comitato statunitense per gli standard per le attrezzature atletiche ha sviluppato un banco di prova per test di urto con testa di manichino a struttura rigida utilizzando un pistone pneumatico solo per urto frontale. Nel programma europeo di valutazione delle auto nuove un manichino comprensivo di una testa con collo flessibile viene utilizzato per testare incidenti automobilistici senza alcun urto specifico sulla testa. US3753301 from 1973 features a mannequin whose head? connected to a neck with a single-body mechanical joint equipped with a viscous damper for two rotations orthogonal to each other. Patent US3877156 of 1975 presents a dummy for impact tests with the articulated head with a connection that allows a limited angular motion only in the sagittal plane. Patent US3916535 of 1975 shows a rigid head of a mannequin with a rigid neck articulated with the head by means of a ball joint. Patent US9972220 of 2018 proposes the cervical segment of artificial column whose vertebral modules are made from rigid bodies that include flexible elements. Patent CN203798525U shows an articulated artificial neck with two rigid vertebral segments connected by a ball joint and connected with two springs to simulate the action of the spinal muscles. The US Committee for Athletic Equipment Standards has developed a rigid structure dummy head impact test rig using a pneumatic piston for frontal impact only. In the European New Car Assessment Program a dummy including a flexible neck head is used to test car crashes without any specific bump on the head.
La presente invenzione presenta un collo artificiale articolare per testa di manichino per sperimentazioni di urti in manichini di testa con una struttura trasportabile e adeguate caratteristiche di simulazione di situazioni di urto. Il collo artificiale articolare per testa di manichino ? basato su una struttura modulare con elementi di vertebra riproducente il segmento cervicale della colonna vertebrale umana permettendo di effettuare prove d?urto in un manichino con diverse condizioni in termini di valori di tempo ed intensit? d?urto con possibilit? di valutare il contributo del collo alla risposta all?urto tramite sensori inclusi nella struttura del collo artificiale. The present invention presents an artificial articular neck for a manikin head for impact experiments in head mannequins with a transportable structure and suitable characteristics for simulating impact situations. The articular artificial neck for mannequin head? based on a modular structure with elements of vertebrae reproducing the cervical segment of the human vertebral column allowing to carry out impact tests in a manikin with different conditions in terms of time and intensity values. d? impact with possibility? to evaluate the contribution of the neck to the impact response using sensors included in the structure of the artificial neck.
