300 TD seat belts..... whats that part in the B pillar?
My friends 85 California 300TD seems to be having seat belt problems.The belts will not pull out at various times... they are intermittent.
The part of the belt that goes down n the B pillar and covered by a plastic shroud is the area in question. What is the best method for freeing up the belts and what is that tubular canister thing that attaches to the belt and has a electrical connection to it. It has some sort of danger explosive sign on it? I did a short search but found zippo...

Part of SRS that's a step up from the older RS is seatbelt pretensioners. Under severe deceleration such as on impact, an explosive charge will reel in the slack and lock the seatbelts. Once this happens, the seatbelt assembly has to be replaced.
My guess is the pendulum mechanism that temporarily locks the belts around turns or while decelerating is sticking and temporarily locking the belts. This might also occur when the car is on an incline. Sixto 87 300D |

The TD must be an 85? My 85 300 has the same set up, think from what I have read 85 was the first year.
when we first bought the car the seat belt either would not pull out, or would stay out, and not rewind, or 1/2 way in between. So bought a new one from the dealer. rather pricy, but Iam not cutting corners on a seat belt. Seems like it was $200.00 or so. that was about 10 yrs back. Charlie

Yup, its your seatbelt pretensioner. Another safety first, from Mercedes.
