Seat Runner Fixing Method

Post by BigBlueVan »

Hi All,
The seat runners which were installed in my van were only bolted in using M6 capheads and nutserts.
This does not look standard and there was plenty of additional holes drilled in proximity to them making me think they had been removed at some point as there was evidence of some patch repairs being performed in the past.

What method is acceptable to pass MOT etc for the fixing of these runners..
Welded in or nut and bolt?

Regards.

Mine, when standard were spot welded. Probably about a dozen in total, in two rows. I assume your nutserts are much the same as a rivnut? Depending on how many are used, they should be of a similar strength. Especially if the nutserts are steel rather than aluminium.

Yeh nutserts and rivnuts are the same thing. Being as you have confirmed they were welded at factory I might just refit them that way to avoid any issues. Thanks.

to put that into context our seats are only fixed to the upper runners by 4 off 6mm HT bolts through the frame into welded half to 3/4 nuts, a lot of 80s era Recaro seats were only secured to the runners the same way, then they went to 6 off, nowadays I think seats might use M8s to bolt them to the runners
