Abstract: A safety structure for disassembling and positioning an airbag device comprises an actuating device having an air bottle and pivotally connected to a positioning member. A quick male and female connection means is provided between the airbag device and the corresponding structure, and a safety device is used to engage and disengage with the quick male and female connection means. A check device is disposed at an air tap of the airbag device, such that the airbag device keeps in the inflation state after being disassembled. The positioning member is disposed with an engaging member corresponding to the engaging structure of the actuating device to adjust the tightness between the positioning member and the actuating device. A retaining device comprises a vent rod and an airtight stopper, which allows the airbag device to deflate or inflate, such that the airbag device can be used repeatedly.

Abstract: A safety device includes a base and a cap pivotably connected to the base at one end thereof. The cap has a watch on a top thereof and a protrusion extending from an underside thereof. A pressurized air container has its sealed end inserted in an opening of the protrusion and a distal end of the container extends from the cap. A passage is defined in the protrusion and a cylindrical member is movably received. The cylindrical member includes a probe which is located in the chamber of the protrusion and beside the sealed end of the container. An inflatable piece is received in the base and has an inlet member which is engaged with the chamber defined in the protrusion. A link is pivotably connected between the cylindrical member and the cylindrical member such that when pivoting the container, the link moves the cylindrical member to let the probe break through the sealed end of the container such that the inflatable piece is inflated.
