ABSTRACT:
The inflator (10) for inflating a pneumatic protective article or gear comprises a gas-containing bottle (17) with a sealing cap (19) applied thereto, an inflator housing (12), a striking member (13) contained in the inflator housing (12) and capable of moving lengthwise therein and provided at a first end thereof with a protruding piercing pin (16) adapted to make a hole in the sealing cap (19), a coil compression spring (21) contained in the inflator housing (12) and adapted to urge the striking member (13) at a second end thereof, opposite to the first end carrying the piercing pin (16), and to drive the striking member (13) against the sealing cap (19) of the bottle (17), a gas outlet port (20) provided in a wall of the inflator housing (12) for permitting the gas contained in the bottle (17) to flow from the inflator (10) into the pneumatic protective article or gear, holding means (24, 25) associated with the inflator (10) and co-operating with the striking member (13) in order to releasably hold it in a cocked condition against the action of the coil compression spring (21), actuation means (26) associated with the inflator (10) and adapted to release the holding means (24, 25), control means (28) associated with the actuation means (21) and adapted to operate the inflator (10) by causing the actuation means to release the holding means. The shape of the piercing pin (16) prevents it from remaining stuck inside the hole made in the sealing cap (19) of the bottle (17). The backward travel of the piercing pin (16), once the sealing cap (19) is perforated, is not contrasted by the coil compression spring (21).
