The driver's belt on my '85 would occasionally stick and not want to pull out. I found that the ratchet mechanism was sticking due to 20+ years of dust and dirt. I vacuumed the b-pillar, used compressed air to blow out the dust, and lubed the moving parts with tiny amounts of light oil. It was interesting to see that the '85 300D (W123, OM617) has the pyrotechnic tighteners.

Interesting since most USA-imported W123s at that time did not have airbags so there is nothing to tell the seatbelt pyros to fire. I guess it was just easier for the factory to install the pyros on every car whether it was destined to get an airbag or not.
