Raise driver seat

I consider to raise the back of the driver seat in 2017 Versa S about 1-1/4" by replacing rear bolts, which attach back of seat rails to the floor, with longer bolts and spacers.

Currently I use a pillow to raise me, but it puts my head in a very uncomfortable position against forward bent non-removable headrest, and my head is being bent forward by that headrest, so in order to keep my head and my back more or less straight, I have to keep only the lower part of my back to be supported by the seat back. It works for short drives, but sucks for longer ones.

That rules out driver seat pads and cushions which I found on Amazon.

Seating without a pillow gives more comfortable seating position (I would not call it very comfortable, but it is acceptable). However, it puts me in a very low seating position where I cannot safely see what is going on around me.

Therefore just raising a back of the driver seat seems like a valuable solution allowing me to seat more or less comfortable, while having a good visibility around me.

I looked at how driver seat rail is connected to the floor. The front mounts are angled and cannot be raised, but the rear ones should be easy to rise with the right bolts and spacers.

I found it was done to other cars, but did not find for Versa. Did anyone do it to Versa? All comments and recommendations are much appreciated.

You're going to sadly find out that raising only the back of the seat is going to make the headrest even more forward bent, you have not thought that out at all.

THINK.

You better start thinking about the front mounts too, they WILL be changing in angularity when you lift the back up.

And the entire thing is unsafe as you have modified the OEM seat restraint, at the very least you MUST have grade bolt materials and likely that if you are in an accident and the seat tears loose, you will be some lawyer's b-tch for the rest of your life when you get sued for modding the seat. If a safety inspector gets wind of it he should be failing the car. Lawyers specifically look for things like that when doing a lawsuit.

I realize the problem but your solution is nowhere near complete enough.

I agree with amc49, I can't see how tilting it forward without raising the front would help in the slightest for comfort.

I would suggest you try to find a salvage yard or pick-n-pull near you that has the six-way manual seat some of the higher-trim level cars had. Those ones can be raised and lowered IIRC (can someone with the fancier seats confirm that?) so if you get one of those bolted in you would have the adjustment you need to be comfortable and still have a 100% stock/OEM seat installed properly so no potential safety or legal issue.

Of course raising just the back of the seat will change the angle of the seat bending it a little more forward, together with the headrest. There is nothing sad about it. The simple solution is after the seat is raised, just to recline the seat together with the headrest back to the angle it was before it was raised. So this one is not a problem.

Yes, the front mounts will be changing in angularity, but a little bit. Before replacement the front bolts need to be loosen, then the rear bolts replaced together with spacers, and the front bolts to be tightening back. It is not a big deal.

You are absolutely correct about grade bolt materials. I looked at the OEM bolts, they are stamped grade 8, which is a notch above usually used grade 5. So the replacement bolts should be at least grade 8. No problem with that one.

After a close examination I saw actual problem with raising the back of the seat: The seat rails have studs which are inserted into holes in the car frame. The purpose of those studs is to keep correct distance between rails so that the seat can easy slide against the rails. The bolts are a little loose against the mounts and are only to tighten rails down to the floor.

If the back of the seat is lifted, those studs in the rear of the seat rails become disconnected from their holes, the correct distance between rails is not set, and the seat may not move easy against the rails.

This is apparently related only to Versa. When I read about other people lifting rear of driver seats for their cars, nobody was mentioning that point.

Well, you need a t45 socket and 1/2 drive wrench for the 2 rear bolts. The inner one has a dowel alignment pin next to it so a stack of washers may not work that well unless you remove the pin.

Id leave the front alone and just guerilla it up high enough for your spacers.

Of course this may screw up how the car handles a crash, air bags, etc. Dont blame us if you do it.

Me, Im the reverse. I need to sit back at an angle for my back pain to ease up. I normally put a stack of washers under the front mounts assuming they are vertically mounted.

I'm missing how the headrest caused issue with a pillow but not with the back raised only, the seat could have been adjusted in EITHER case. IF of course someone mentioned it.

I myself see no mod issues stopping things other than it is illegal to mod seat mounts and you won't find out until they sue you over it. The studs can easily be lengthened, dowels can be modified to work. I used to do stuff like that on race cars all day long. There are a hundred different ways to mount seats if not more.

Again, if a safety inspector sees it, he if doing his job will reject it. Be ready for that.

Cool

Ive had my seats raked back in every car Ive owned since I got out of a wheelchair some time ago. Notice how its seat is raked back.



I havent had any problems.

I thought about it, but the 2017 Versa S has additional side mounted air bags, located in the seats. Replacing the driver seat with another one would take the driver side airbag out of equation. Don't think I want to do it.

Is the headrest in the 2017 Versa S not adjustable?
It seems like you would be able to raise the headrest and not mess with trying to raise the whole seatback?

Find somebody with service manual access and check how to remove the headrest, many do come out and the bar can often then be bent to suite.

Don't switch seat, I've heard of horror stories trying to match them up with bag modules that insist on finding the exact same thing there or they never go active. If you do, the seat commonly has to be the same year to interface with the module and the connector changes under seat can drive you NUTS. They INTEND for those systems not to be messed with at all, too many do and then sue the OEM themselves later after the bags refused to work because somebody messed with the system. Just removing the airbag in one position commonly shuts the whole thing down, the software must match what it expects to physically be in the car.
