Total Human Model for Safety - THUMS

THUMS AM50 sitting and standing


The To­tal Hu­man Mod­el for Safe­ty, or THUMS™, is a joint de­vel­op­ment of Toy­ota Mo­tor Cor­po­ra­tion and Toy­ota Cen­tral R&D Labs. Un­like dum­my mod­els, which are sim­pli­fied rep­re­sen­ta­tion of hu­mans, THUMS rep­re­sents ac­tu­al hu­mans in de­tail, in­clud­ing the out­er shape, but al­so bones, mus­cles, lig­a­ments, ten­dons, and in­ter­nal or­gans. There­fore, THUMS can be used in au­to­mo­tive crash sim­u­la­tions to iden­ti­fy safe­ty prob­lems and find their so­lu­tions.

THUMS is lim­it­ed to civil­ian use and may un­der no cir­cum­stances be used in mil­i­tary ap­pli­ca­tions.
