Modifying MGA Seats for Comfort |
|
|
|
I put up with standard MGA seats for 7 years. They are completely
the wrong shape - the back rest is too vertical so there is no lower
back support, and the base is too flat so there is no lower leg support.
It was the prospect of driving 3,000 miles across Europe that finally
motivated me to do something about it.

The photo shows the modified seats. They are standard MGA seats
that have been rotated backwards.
Tipping the seats back increases lower leg and lumbar support
(and I've stuffed a little more padding in the lower part of the
seat back to further increase lumbar support). |

Simply tilting the whole seat back by propping up the front
with a bit of wood would have posed issues in fore-aft adjustment.
Here I've cut the seat rails off the front of the seat frame
and tied the rails together with an additional bar to retain their
position. |

New gussets on the seat base frame mount a couple of bolts
with washers welded to their base. The bolts screw into the additional
bar and provide a means for adjustment.
The seat rails are welded to the rear of the seat base as normal.
so this new adjustment tilts both the seat base and back backwards. |

While I was at it I decided to put some independant adjustment
into the seat back by making some new mountings for the squab
that were a little taller than the originals.
|

 |
I welded some nuts into the rear of the seat base and screwed
a couple of bolts in. The rail at the bottom of the seat back
fits on top of the bolts which provide a means of adjusting the
seat back angle.

I modified the passenger seat too, but only did the first modification for
tilting the whole seat rather than independent seat back and base adjustment.
It's quite comfy, so maybe the second modification is not necessary.
