Default Upper (shoulder) seatbelts - not tight?

All,

I've read through the posts, and see that there is an inertia pendulum that should lock the seatbelts under rapid deceleration.

On my tests, and in other cars, often pulling quickly on the seatbelt will prove the lock, but on my ZR1 no amount of pulling it quickly does anything - for both driver and passenger...

I'd believe that this is as intended - wouldn't expect both to be bad...

So question is: is an elastic shoulder belt normal? And do I need real deceleration (rather than just pulling it sharply) to get the seat belt hold??

I'm not looking for cinching (this works fine, and as advertised), just the surety that the belt will stop... when it needs to!

Thanks

Steve

Only know of a few ways to check, first would be a very hard stop from 25mph, other would require removing the assembly and checking the pendulum.

maybe someone else knows a better way.

I can tell you that on my seat belts if I pull them to fast when buckling they will lock.

Had the exact same thing on my '87 convertible. Only way to get it to tighten up was to unfasten and then refasten the belt. Would love to hear someone chime in with the cause so I'll know how to fix when it happens to my Z!

The take-up reel on my driver side belt is not wanting to take up the slack,when I buckle up. Any ideas?

I believe there was a recall campaign on this issue....although due to age it is no longer in effect.
