The 1993 French patent would have expired.
BTW, for those that actually read the patent to try to figure out where Aerodyne might be infringing it, you might find the following useful:
Only the "Claims" section specifies what the patent covers. The preceding sections help you understand things, and can define what terms actually mean, but unless it is in a claim, it is not something that is covered by the patent that they were granted.
There are 21 claims, and for this patent, claim 1 is the broadest claim. All subsequent claims are based off of this one by adding one or more additional descriptions that further specify elements in claim 1 (and so, they narrow the coverage of the claim). For example in claim #17 they state that a particular "connector" in claim 1 is formed by a loop of the lanyard. This is typical of patents, where claim 1 is quite vague of about the particulars of an element, and then subsequent claims get more particular. (E.g., Claim 1: "A car with tires." Claim 2: "A car with 4 tires." Claim 3: "A car with 4 tires made of 95.3% rubber and 4.7% polyester")
So, *IF* claim 1 is valid (i.e., that claim can *not* be defeated by proving that that claim of the patent should not have been granted), then if they don't infringe claim #1, they don't infringe the patent. You don't need to look at claims 2-21 (because they have to infringe #1 in order to infringe any of the others). And to infringe a patent claim, one has to infringe each and every element in the claim.
[Now if claim 1 can be defeated, (for example, by showing that one element was prior art and thus not patentable) then you might have to look at the other claims. Maybe connectors were used in the past to do what they are doing for one element in claim 1, and so on that basis claim 1 is ruled invalid, but maybe it is novel to make a connector from a loop of the lanyard, in which case claim 17 could still be valid.]
