Passenger seat won’t fit a grown man comfortably.

[08hmmwv]

Has anyone changed their front passenger seat to accommodate more leg and knee space? It’s very very tight.

Keep in mind that the base is the battery box and cant be easily moved. Now remove the thinly cushioned GI seat and install a thicker, taller bestop jeep seat or similar...You will probably end up with less room.

Do you have the newer high back GI seats, or the original style pop-tart cushions?

You think it's bad now? Try cramming yourself in there wearing all your "battle rattle" and your rifle.
It's cramped even for a thin, healthy guy.

I'd be tickled to have those style seats. We use standard issue bleacher pads and weak springs for driver. I hope to have money for a seats upgrade mid-year.

First thing I did was change out the flat front seats for the high backs.

I replaced the two brackets that connected the upper and lower seat cushions. They were too upright and crammed you against the wheel.

I fabbed these up that let the seat back recline.

Any more pics? That looks just like what I need to do

Nice, did you use the same bracket and made the slide track ? And what does the other side look like

I had to make new to have enough meat to have the slide track. Both sides of both seats are identical. The knob was from home deeps

I just copied the original bolt spacing but I want to make a new set to close up that gap so everything i set on the seat doesnt funnel through it into the black hole behind the seat

I'd like to nominate your adjustable seat back design for most unique and down right ingenious upgrade .
It should come standard from the manufacturer.
I salute your ingenuity and willingness to share your design.
You should market them before I copy it.

After careful consideration, I will be adding heavy gauge right angle bent (vs. welded) rocker panel re-enforcements and square tube steel inner rocker re-enforcements to the sides and I will be deleting the upper aspect of side to side square tube re-enforcement by using a thinner beefier square tube placed lower down to the floor. That will allow the seats to be set further back while protecting occupants from a side impact.

This will be a Summer project, and won't be happening anytime soon, so no pictures yet.

In a rear end impact, I'm concerned that this will fail, but I think your ingenuity is terrific. To adjust, you should not have a groove, rather 2 or three set position holes to lock the seat in a position that cannot slide on impact. It would make adjustment fiddly, but would make the design more secure on impact.

I will be swapping to some other seat in the future, after I re-enforce and modify side impact protection.

Thanks
I cant really take credit for this "design" though... i've seen it before in other seats. I just had access to the stuff to make them

Thats a great point.
But I would argue that many seats fail that way in a rear end collision. Its like the crumple zones in cars or aircraft seats.
The lack of upper torso/head restraints would cause me to surmise that maybe the seat back reclining you a little would be preferable.

My first idea was to just drill an extra hole in the original parts.
The adjustment was indeed fiddly.
