Abstract
Motorcycle helmets manufactured in developing countries such as Tunisia are not specially designed, adapted or modified to provide extra comfort especially in hot and humid environment. In this study, three comfort liners manufactured from natural fibers are proposed and compared with standard liners. Subjective evaluation based on subject’s opinions and objective evaluation using liners characteristics: are used in this comparison. It was found that non woven liner made from wool and alfa fibre is more advantageous in term of comfort and acceptance than the other liner. It was judged comfortable, acceptable, not sweating and not hot. This result was confirmed by liners characteristics witch can convince helmet designer that more work is needed in this aspect.
Highlights
Protective headgears are intended to protect the head against impacts or objects falling from a height in environments
We propose three comfort liners for Tunisian helmet
These liners will be compared to a standard liner using subjective evaluations
Summary
Protective headgears are intended to protect the head against impacts or objects falling from a height in environments. In hot and humid climate such as of Tunisia, many workers and motorcycles are less willing to wear helmets because they are uncomfortable [1,2]. The adding ventilation holes or slots can be considered with significant effect for intensifying forced convection and evaporative convection [3,4,5,6]. Characteristics of helmets such as effective materials, colour and general construction have been examined and selected to optimize heat transfer from the human head to the environment [7,8]. Abeyeskera et al [9] affirmed that these studies and suggestions have led to some improvement in the design of protective headwear
