Abstract:
1. An inflating and separating device of body protection airbags for riders, having a joint connected to the interior of an airbag and coupled to an inflating device, and an end of the inflating device being coupled to a compressed gas cylinder, a firing pin being disposed inside and movably installed at a position facing said compressed gas cylinder, and another end including a striking device pivotably coupled to the inflating device, wherein said striking device having a pulling handle for pushing said firing pin, and at least one hole being disposed at a connecting position of said pulling handle, characterized in that: said inflating device is coupled to an end of said compressed gas cylinder having a ventilated board with at least two ventholes, and a gas leaking space is disposed between a sealed opening and said ventilated board of said compressed gas cylinder, and a plurality of grooves is disposed at a lateral side of the tip of said firing pin, a leakproof ring disposed at a rear end of said firing pin, such that the gas in said compressed gas cylinder can inflate a space of said airbag immediately after said firing pin pierces said sealed opening and then after said firing pin is withdrawn to the position of said sealed opening, and wherein said pulling handle of said striking device includes a plurality of corresponding holes for engaging and detachable coupling with at least one protruded points disposed on the inflation device, wherein selective use of varied number of said protruded points allows for the adjustment of a first pulling force necessary to move said pulling handle, and said pulling handle has an end coupled to a first end of a pulling string, and a second end of the pulling string is coupled to a mid-portion of a separating device, and said separating device is in the shape of a hollow pipe having two terminal ends and a pin hole disposed transverse to a longitudinal axis of the hollow pipe for inserting an insert bolt which has an insert end that has two symmetrical arc grooves, and both terminal ends of said separating device respectively include a first and second lockholes for securing a first and second screw bolts, a first and second circular members being biased towards each other by a first and second springs disposed within said first and second lockholes, and said first and second screw bolts biase said first and second springs so that said circular members bias against said arc grooves of said insert bolt, and the tightness of the biasing force by said first and second circular members can be adjusted by turning said first and second screw bolts according to a rider's body weight and a riding object to set a second pulling force, and said second pulling force is larger than the first pulling force of triggering said striking device, and wherein the insert bolt is coupled to a cord which is attachable to said riding object.
