Abstract [en]

The aim of this master's thesis was to further develop a helmet for search and rescue personnel, on request from AUK Protection, formerly known as Baering. This thesis succeeds the KTH MF2061 higher course project Baering Y1 - Product development of a new search and rescue helmet in collaboration with Baering in 2013. AUK Protection had identified a need for a purposely designed helmet through contact with members of Swedish Search and Rescue(SAR) and Swedish Sea Rescue Society(SSRS). There are approximately 2000 active SAR and SSRS members who use helmets designed for recreational activities, such as rafting and mountain climbing, for lack of a better alternative. The helmets are consequently modified to accommodate their specific needs. Essential rescue equipment, such as position lights and communication systems, are retrofit using fasteners, tape, straps and Velcro. User studies conducted in the MF2061 project indicated safety concerns with the aforementioned attachment methods. The retrofit components protrude from the helmet and often interfere with other rescue equipment, with the risk of entangling the user. The Y1 helmet concept produced in the MF2061 project was evaluated together members from SAR and SSRS, with focus on form and functionality. Different materials and manufacturing methods were researched and the manufacturability of the Y1 was analysed. It was ultimately decided to discontinue the development of the Y1 due to the feedback received. New concepts were generated with focus on anthropometric data, manufacturability, helmet safety standards and the ability to mount additional components. Different material combinations were investigated and evaluated using physical testing. Further development of the concepts involved clay sculpting and 3D CAD modelling. The final concept was chosen based on input from the users, AUK Protection and HOWL Design Studio. The R1 -Rescue One helmet is the result and supersedes currently available solutions for rescue applications. The essence of the R1 helmet is a modular mounting system that can be customized for use with third-party components. Prototypes were manufactured in the correct materials for further evaluation. Drop tests were performed according to PAS 028 standard validate the mechanical properties of the helmet.

Abstract [sv]

Syftet med denna magisteruppsats var att vidareutveckla en hjälm för livräddningspersonal, som gjordes på begäran från AUK Protection, tidigare känd som Baering. Denna avhandling efterföljer MF2061 högre kurs-projektet Baering Y1 - Product development of a new search and rescue helmet in collaboration with Baering som genomfördes i KTH år 2013. AUK Protection hade identifierat ett behov av en speciellt utformad hjälm genom kontakt med medlemmar i svenska Search and Rescue(SAR) samt Sjöräddningssällskapet(SSRS). Det finns omkring 2000 aktiva SAR och SSRS medlemmar som använder hjälmar avsedda för fritidsaktiviteter, såsom forsränning och bergsklättring, i brist på ett bättre alternativ. Hjälmarna modifieras följaktligen för att tillgodose deras specifika behov. Nödvändig räddningsutrustning, exempelvis positionsljus och kommunikationssystem, monteras på hjälmen med hjälp av skruvar, tejp och kardborreband. Användarstudier i MF2061-projektet indikerade att dessa monteringsmetoder medför säkerhetsrisker. Enligt SAR Norrtälje hakar utstickande komponenter som är monterade på hjälmen ofta fast i övrig räddningsutrustning, med risk för att trassla in användaren. Y1 hjälmkonceptet, som produceras i MF2061-projektet, utvärderades med avseende på form och funktion tillsammans medlemmar från SAR och SSRS. Olika material och tillverkningsmetoder undersöktes och producerbarheten av Y1 analyserades. Det beslutades slutligen att avbryta vidareutvecklingen av Y1 baserat på feedbacken som erhölls. Nya koncept genererades med fokus på antropometrisk data, producerbarhet, säkerhetsstandarder för hjälmar och förmågan att montera ytterligare komponenter. Olika materialkombinationer undersöktes och jämfördes med hjälp av fysiska tester. Vidareutvecklingen av koncept involverade skulptering i lera och 3D CAD modellering. Det slutliga konceptet valdes utifrån input från användarna, AUK Protection och HOWL Design Studio. Resultatet, hjälmen R1 - Rescue One, ersätter tillgängliga lösningar för räddningsapplikationer. Det som utmärker R1-hjälmen är ett modulärt monteringssystem som kan anpassas för användning av tredjepartskomponenter. Prototyper av R1 tillverkades i korrekta material för vidare utvärdering. Falltester utfördes i enlighet med PAS 028 standarden för att validera de mekaniska egenskaperna hos hjälmen.
