Abstract
A device for providing protection against the debris produced by a bolt that can be cut by a pyro bolt cutter, in particular through the use of a pyrotechnic device, the device including a confinement enclosure which surrounds the body of the bolt where it leaves the cutting device, and including resiliently deformable members such as membranes that are slit in their centers, with the body of the bolt passing in a substantially sealed manner through the centers of the membranes. The device serves to trap inside the confinement enclosure the debris that are produced when the bolt is cut, and it is particularly applicable to the aerospace industry.
