Automatic seatbelt height

[iainand]

hey guys, can someone help here?

my front seatbelts no longer adjust up or down with seat movement, i found the wires off under the seats, but one problem i dont know where or how they fit on again, can someone help???

Note, my car doesnt have electric seats

maybe it is the same as the seat twist problem where the end of the cable has come out of the drive gear.You may need to shorten the cable outer a bit.
There are various wires under the seat that arent used...ie heated seats ,memory seats,etc.
I am pretty sure the seatbelt height is driven straight off the fore aft movement motor....i might be wrong tho..

There is no motor involved. just a cable attached to the seat.

The mechanical seat belt height adjuster works on a steel cable.

The cable has a 'clip-thing' attached to the end, which a fastening clasp goes thru, then thru a whole in the seat frame, then the clasp clips over the 'clip-thingy'. Confused??

Great diagrams Nick. Inspires me to tackle something that has been bugging me. Shogun you must have a great camera--the pictures are always so clear and sharp.

Something is not right with 3 of the 4 front belts on our 525 and 535. They function ok from a safety point but when we unlatch them, the excess belt does not retract on 3 of them. The excess just flops around and gets caught in the door. Is that what this wire and clip do, make that excess retract, or is this thread talking about a different problem?

I wouldn't think of that as a "height adjustment" but I obviously have not recognized a height adjustment when I have seen one cause I have no clue what that means.

If this thread is not about my seatbelt problem, what does fix it?

Gayle, the wire attaches to the outboard seat rail, as many have noted, routes through a guide wheel mounted at the front of the frame on the floor and up the b pillar to the seat belt mechanism. "Height Adjustable" means that as the seat is moved forward or backward, the tracking point for the belt moves to compensate the *predicted* height of the seat occupant based on the distance from the seat to the steering wheel. It's not that technical, only a cable fastened at two ends with some spring tension in between to keep things tight.

If the adjust mechanism is broken or the cable latch is disconnected from the seat: the belt height adjuster will bottom out and stay that way regardless of where the seat moves (forward/backward). This will sometimes cause the belt to get caught (ratcheted in place as it should under extreme movement) if the seat is moved around (all the way back, then moved foward). Passengers complain because they seemingly can't get the belt off of the wall; it usually unlocks itself if the seat is moved backwards and forwards again.

someday I really have to see whats missing under my drivers seat...this is all the info I need but I think my bracket thing is gone.

Does any one know the part no. for the bolt, that attatches to the clip on the wire, to the seat rail?

Is there some sort of spring tension inside the black wheel on the floor, which the wire goes through? Meaning, that on both my seats, when I move the seat forward, the seatbelt adjuster is supposed to move down. But it doesn´t and there is plenty of slack on the wire lying on the floor. Not until i pull on the seatbelt itself, the adjuster goes to the right place.

What part no. do I need to fix the adjuster on both my seats?

Thanks for any input

[shogun]

you need the complete wire system (bowden cable), see these 3 pics, one is pull out by the seat, the other one is pushed in by the seat.
Or go in ta motorbike shop and by the single parts to solder the end piece onto the bowden cable, they have bowden cable by the yard.

check the parts based on your VIN, I am not sure if you have this system

From your link, it appears that the bolt that goes in the seat rail to fasten the wire is NLA. I will look in a junkyard for this part.

What I am interested in knowing, is the mechanism which holds the wire tight (and subsequently moves the adjuster) inside the black wheel on the floor or is it in the b-pillar adjusting device?

Is it part no. 9 in the b-pillar or is it part no. 17 on the floor, from your link?

The black wheel block is mounted on the floor. If you find an E34 at the breakers you will be able to see how it all works when you pry the small retaining clips out.

apparently the pics I attached do not work. Here once more, the black wheel under the seat is the one which makes it all
