Out tonight with the wife, and she complained about it, again...

I'm going to look into spacers and longer bolts. Even an inch would be a noticeable difference.

(Irony: I'm lowering the passenger seat of my Miata to match the driver's seat, which I did years ago. The impetus is a real roll bar, installation of which necessitates removing the passenger seat. It just seems stupid to re-install the OEM seat rails...)
 
Looking at how the Accord's seat is bolted to the floor, the rear bolts are vertical, but the front bolts are at an angle, maybe 30° off vertical.

So, it would be easy to install spacers and longer bolts the rear and bring the rear of the seat up, but it's almost impossible (for me, at least) to raise the front of the seat.

Except... Here's a custom kit that does it:

Great find! Good to know the rear is bolted. I hadn't looked into this yet since I rarely have passengers.
I'll probably just make my own blocks since I already have some aluminum bar stock and taps in common seat bolt sizes. That design shows that even a 3/4" block will offset the holes enough to avoid overlap at the angle of the bolts. I'll probably go 1.5" in front and 1" in back. My people are not tall.

How 'bout making a batch, and selling them via this forum? I'd happily pay up front for a set, especially the fronts.

(The rear spacers are just straight-through stupid-simple blocks, and longer bolts, and even I can figure that out... I might even just make them out of blocks of maple.)
 
Does the overseas Accord/Inspire have the height adjustable passenger seat? If so, you might be able to switch the seat tracks over to the height adjustable version. That is, if you can get the parts to do it.

Thanks a lot for sharing this. I think I will order them for my driver seat. I see it can work for both driver and passenger seats. I know the passenger seat will benefit from it too for sure. I will have to order for both seats then. Let me look more into this.

Does anybody know if there is one for the rear? These are only for the front of the seats. Any links for one for the rears?

All you need is a metal spacer with sufficient surface area and a hole in the middle. A heavy square nut with threads bigger than the seat bolt's could work.
I always keep strut channel washers on hand for projects. They are about 1/4 thick. Easier to stack than regular washers and most definitely strong enough for any purpose.

You'll probably need longer bolts too. I recommend grade 8, flange head bolts for best safety factor when clamping down stamped sheet steel like seat tracks. If the manufacturer used a flange head bold then I'm going to replace it with one. Cap head screws are not a good choice unless you have thick washers with a precisely sized hole to prevent tear-out in a crash. I always approach modifications like these with caution. You don't want to risk adding a weaker element.

Given that they sell these in RHD markets, the "passenger" seat would be the driver's seat, and presumably fully adjustable... How nice it would be to get a complete seat out of a wreck, for cheap!

Shipping a seat internationally is typically crazy expensive, though...

Like 2Many said, the rears are a simple DIY block or stack of washers, with a new longer bolt.

And like he said, don't scrimp on the bolt...

Lol, let us go to Japan and find one and bring back!

As for the rear seat jackers, that sounds really easy. It would be nice for someone to get it done and share with us how to do it. Pics and prices.

I basically just called that company above and they said they are sure the rear they sell for a Tacoman or Tundra would work for the Honda. They asked me to please send them some good pictures of the rear so they can let me know if it will work for sure. And if I buy it and it does not work, I can send it back to them.

This advice is of the utmost importance.

take heed of it.
 
OK, so I actually took a look at the seat bolts and they've used a seat-belt style with a torx plus head, probably a TP47. I don't have TP47 at the moment so I can't pull one out to verify length, thread size and pitch. It's a very low profile head, presumably so the upper track can slide over it. There's enough width for a flange head but I'd certainly try replacing one first to see if there is enough height clearance. In might need to be ground down, possibly too much to leave enough hex to grip. Perhaps the proper bolt could be sourced once all the details are determined. The size of the hole in the track is important are many multiple configurations of shoulder lengths and diameters. I usually keep seat belt bolts when I scrap something because you never know what you might need. You won't find this stuff at the hardware or auto parts store.

Actually, I was referring to the LHD versions being sold overseas.

You wouldn’t need to buy the whole car, or even the whole seat, you would just need the seat track parts that allow for the passenger seat height adjustment. Of course, this all depends on if that model has the passenger seat height adjustment option or not.

Right, not the whole car (!), but if you got the whole seat (a RHD driver's seat), then you would have the lumbar adjustment, as well...

Also, from what I've seen, people remove seats and sell them whole. They don't typically dismantle the seat itself.

From the Miata world:

Really, it's an easy DIY job with scrap that you probably have lying around. You could buy somebody's "kit," but it'll be <$10 of hardware (retail, <$5 wholesale) and cost $50 or $75.

I guess we will need someone to try and find a "kit" from a local hardware store that would work for our cars. I mean, I would love my seat to feel as high as if I am in a Toyota Crown. That would help a lot. I do miss having a suv and was tempted to get a CR-V, but I wanted a sedan but with the seating of a suv. Only the Toyota Crown offers that.

I am really interested in this seat jackers. I will see if it makes sense to me. But if someone finds a local solution that is cheaper, I would gladly try that. A raised seat would be a lot more comfortable for me when I take long trips where I drive for 12 to 16 hours a day.

The lumbar adjustment would be nice, but if it means more work and fabrication to get it to work on the passenger side, I’d rather go with the easiest way to get the factory height adjustment for now.

The seat tracks are typically bolted to the bottom of the seat frame and then the seat frame/seat track assembly is bolted to the floorboard. If the LHD version has the passenger seat height adjustment option, which it could since those models have more options than the U.S. based Accords, it would be just a matter of locating and buying the seat track assembly parts that have the height adjustment for the passenger side.

That’s why I suggested the Inspire which is sold in LHD versions overseas. It would simplify the swap rather than choosing a RHD version and adapting the driver’s seat on those to work on our cars. I guess either way would work. However, if the LHD Inspire has the passenger seat height adjustment option, then that would probably be the easiest/cheapest/cleanest way to do it for our cars.

You would just need a overseas source to acquire the needed factory parts from Honda.
 
Correction, the seat bolts are TP50. I was able to find mine so I'll be pulling a bolt out soon to investigate. I don't recommend trying to remove torx plus with a regular torx bits.
I'm also thinking the best way to do this is to use a simple spacer in the front which will move the seat forward due to the angle at the front of the track. Then the rear spacer block could handle the resulting offset. The original seat bolt could then be used at the rear eliminating concerns about sliding track clearance, and a commonly available flange head bolt could be used from the bock into the body. Same at the front. This is basically the reverse of the SeatJackers kit.
 
I have lumbar adjustment on my 2024 EX-L. Do you not habe lumbar adjustment?
Driver’s side I do, but not the passenger side. I don’t really need it on the pass. side, just the height adjustment. To do the lumbar too, you‘d need a whole new seat which is more $$$. The height adjustment would just need new seat tracks bolted to the bottom of the seat frame…less $$$ in parts.
