När bilar krocktestas används i regel en docka som utgår från en genomsnittlig mans kropp. Den enda kvinnliga krockdockan som finns är bara 151 centimeter lång och endast ämnad för tester av frontala kollisioner.
Kan det vara en anledning till att kvinnor löper dubbelt så hög risk som män att drabbas av whiplashskador vid påkörningar bakifrån? Det har Chalmersforskaren Anna Carlsson undersökt och utvecklat en prototyp till världens första krockdocka som motsvarar en genomsnittlig kvinna.
Genom att låta kvinnliga försökspersoner i bil bli påkörda bakifrån vid väldigt låga hastigheter har en matematisk modell tagits fram, som sedan stått grund till en prototyp av en krockdocka.
Anna Carlsson kunde bland annat notera att männens och kvinnornas rörelsemönster skiljde sig. Den kvinnliga dockan hade högre accelerationer och rekylen framåt vid en påkörning var mer kraftfull.
– Jag hoppas att min forskning ska leda till bättre whiplashskydd, för både kvinnor och män vid kollisioner bakifrån, säger Anna Carlsson som hoppas på nya anslag för att kunna fortsätta utvecklingen av den kvinnliga krockdockan.
30 000 whiplashskador anmäls årligen i Sverige, 500 personer förtidspensioneras och samhällskostnaderna beräknas vara högre än fyra miljarder kronor.
