Abstract
The present technology relates to a locking device (2) for fixation of the position of an outer layers (4) relatively an inner layer (6) of a protective helmet (3), which protective helmet has a sliding layer (8) arranged between the outer layer and the inner layer, for facilitating displacement of the outer layer relatively the inner layer during an oblique impact towards the protective helmet. The locking device (2) comprises a layer-guiding member (10), that has an upper portion (12), which upper portion (12) is intended to be arranged in an opening (13) in the outer layer (4), and a resilient lower portion (16), extending from the upper portion (12), that in its free end (17) is arranged in connection to the inner layer (6). The present technology also relates to a protective helmet (3) comprising the locking device (2).
