Seat belt anchorage bolts

I have fit my seat belts (new aftermarket) with 7/16-20 Grade 8 bolts. Where provided I used the “low head” 7/16 bolt provided.

How was the original mounted? Did the spacers allow the belt mounting flange to rotate?

Should I get shoulder bolts to allow that movement?

Will that compromise strength as the bolt will be completely in shear?

The original had spacers. Yes, the seat belt lug should be free to rotate.

Seat belt fitting kits typically come with longer bolts & stepped spacers.

Since fully tensile loading is usually difficult to arrange, a bolt in shear is far better than one in bending. Take a look at any OE seatbelt fitment… :wink:

My new Securon seat belts did not have the step spacers. nor did the 4 point TRS belts supplied with the Spyder rear seat belt kit.

I will have o get them somewhere.

I e-mailed Securon. So far no answer.

Any web site for TRS belts? I could not find one.

Finally found the “Total Restraint System” web site. I have contacted them.

Strange that the original Lotus spacers do not fit as the anchorage bolt sizes are the same.

I’ve got a continuing question on this topic. Securon belts.

The RH (US passenger) side fits well. But the other side is forced to fit at an angle. Now, the instructions address this but I’d like another set of eyes to look at this and see if it looks “right”.

Rotating the other way may seem better to feed the belt but the angle is even greater I think?

Thanks,

Attached is a picture of the left side reel. Hope it helps.

TRS responded and said that Spyder requests end fittings that are not compatible with shoulder bolts or step bushings. It appears that they intend for each of the 4 end fittings be bolted fast to the body mounting plates and their replacement crossmember.

Hi,

I knew somthing was different with the mounting of the seat belt mechanism on my car and had chance to look when fitting the window motors this afternoon (see other post!).

On my car the seat belt mechanism is actually bolted onto the inside of the sill onto a heavy duty plate and at the top the belt runs through a heavy duty wire slot or “eye” which is bolted to the body where your mechanism is fitted. Consequently no problems with fitting. The belt turns though 90 degrees as it is pulled between the two mounting points.

I don’t know if this is a PO mod but it works OK.
