Problems solved by technology

However, there is a need to supplement these known fastenings with the possibility of tightening the chin-strap as required in order to improve the effectiveness of the helmet which, as is known, may be impaired--even to a significant degree--if the chin-strap were not properly tightened.
The fastenings known hitherto, which are operationally designed to perform both the functions indicated above, have however undesirably large dimensions such that their use is unsuitable for fastening chin-straps of helmets.
Moreover, in most cases, they have projecting parts which are likely to cause discomfort for the user around the chin or throat.

Abstract

A toothed-belt fastening, in particular for chin-straps of helmets, protective headgear and the like, comprises a base on which the toothed belt can be slidably engaged, a first and a second pawl which are mounted in an oscillating manner on the base and can in turn be engaged with a toothing of the belt. The first pawl forms a member for unidirectionally locking the toothed belt with respect to the base and is disengageable from the toothing so as to slacken the fastening, while the second pawl is engageable with the toothing so as to tension the fastening and is hinged on the base coaxially with the first pawl.

Description

[0001] The present invention relates to a toothed-belt fastening, in particular but not exclusively for tightening the belt which passes underneath the chin, otherwise known as chin-strap, in helmets, protective headgear and the like. Although the use described is the preferred use, this fastening is more generally intended for rapidly tightening and releasing two fastening elements and is therefore suitable for widely varying uses in sports equipment and accessories.TECHNOLOGICAL BACKGROUND[0002] Within the specific technical sector it is known to use rapid-release and rapid-engagement fastenings which allow the fastening to be operated rapidly in all circumstances. However, there is a need to supplement these known fastenings with the possibility of tightening the chin-strap as required in order to improve the effectiveness of the helmet which, as is known, may be impaired--even to a significant degree--if the chin-strap were not properly tightened.[0003] The fastenings known hith...
