Automatic extending protection system for head

摘要

The invention relates to an automatic safety helmet and cover protection which can be worn on the back mainly of people who play sport. The protection means is stored in a rucksack case (3) and is attached to the back by straps (4-6). The case accommodates essentially a guard (11-19), a drive member and a control mechanism. There is storage space in the centre for various implements. By triggering a spring accumulator (40.1, 40.2), the protection means is rotated, in the event of a threatening fall, into an erect protection position in fractions of a second by way of a trigger cord or by automatic actuation due to a sensor (23). Said protection position is held at the top by a toothed catch member (7.1, 7.2). Mating toothing on the catch member maintains the protective position even in the event of a change in direction.
