Why did Lotus design the Passenger Seat to not adjust? - LotusTalk

Trendy Exige · 10-19-2008, 04:11 AM

I find it rather annoying that the passenger seats cannot be adjusted forward/back the same way as the driver side. The trajectory of how the passenger airbag is deployed pending on a specific distance could a possible safety concern why the seating position is fixed. Thats understandable, but you can always adjust the seat all the way back when the passenger is in the car and still allow having the option to slide the seat back and forth when the passenger seat is not occupied.

At the moment, I'm seriously thinking about buying the sliders that goes on the left hand driver seat rails and put them on the passenger side. The passenger seat rails are also bolted down using a different bolt than the driver side. I personally find it much easier to remove the driver seats since ratchet tools are much comfortable to use in tight spaces, especially when trying to loosening the over torqued bolts.

Any warnings or possible negative impacts for doing so? If there are any reason why I should not do this, please don't hesitate to explain.

Although ive only test drove an elise and never sat in the passenger seat. Would it be easier to get an entire drivers seat with sliders and bolt it in. or does the passenger seat fit on the driver side sliders? Just a thougt.

My car is RHD, 111R.
No airbags here and still the passenger seat is non adjustable.
I think its for weight saving purpose.

habendanio · 10-19-2008, 04:46 AM

because the drivers seat is toward the center and the passenger seat has no room to travel without hitting the sills

All the passengers have to do is hold on.

RacyTracy · 10-19-2008, 05:14 AM

Are you saying you want to be able to move the passenger seat forward when there is no passenger? Just being nosy.....but why?

I can only imagine for storage space

But as habendanio has pointed out the seats are not mounted symetrically and as such there is no room for the passenger seat to move.

RacyTracy · 10-19-2008, 05:29 AM

C'mon, somebody say 'So the person in back can see the TV in the headrest easier'.....Oh wait, I just did.

Too bad they didn't make the seat tip forward for rear-panel access and getting chnge out from under the seat easier. But in the name of weight-saving.......every ounce counts.

The early Porsche 914 passenger seat was fixed also.

I was gonna say so the passenger can have a better view of the engine in action

"Why did Lotus design the Passenger Seat to not adjust?"

Most likely for weight savings, simplicity of design, cost control, and utility.

The passenger really has nothing to adjust for...no occupant in the back seat to make room for, and no control pedals to reach.

Save your money - you can't use them.

Nothing to do with it.

Bingo, give the man a cigar. If you look carefully at the seats and their mountings, you will notice that there are two set of mounting holes - one set for LHD cars, and one for RHD cars. As pointed out, the seats are shifted to the right on LHD cars. The passenger side is close to the side sills. The side sills curve in slightly just ahead of the seats, and if you were to move the passenger seat forward, it would almost immediately hit the side sill preventing it from sliding forward. I'm not sure that the sliders could even fit, but if you did fit them, the seat would be prevented from sliding forward by the side sill.

By the way, not only are the seats are shifted to the right, but the rear view mirror is not centered - it's shifted slightly to the right.

Hooray, you win the thread.

khamai · 10-19-2008, 10:24 AM

Sliding rails would fit, but the seat would virtually have no ability to slide (as others have correctly pointed out).

This question has some history. It was asked shortly after the cars started getting to customers in mid-2004 and the factory response was "Yes, but it won't slide."

I got to sit there when the wife exercises her turn to drive.

I actually like that it is fixed as there is really no reason for it to move. Saves weight, costs, and complexity.

Because crap gets stuck under there and you can't get it out unless you have really tiny hands...

My wallet was stuck under the back side of the passenger seat once. That was not fun.

Trendy Exige · 10-19-2008, 04:15 PM

I just measured it and realized that the the seat rail brackets are closer together on the passenger seat than the driver seat.

The difference is the equivalent distance where the two set of mounting holes are.

What about making sliders for the brackets that hold the passenger seat? Any Lotus engineers want to come up with that? If you make it, I will buy it! (as long its reasonably priced)

I've seen so many people designing clever tools that make our Lotus more enjoyable to work on.

Anyone?

Yeah, I had to use duct tape on a stick several times......

Gizmo3000 · 10-19-2008, 08:32 PM

I totally get why the passenger seat is fixed
(one less thing to break as well!)

tho while it makes complete sense for so many reasons.
- it still kinda wish it could slide forward a tad.
I'm a short guy (5'5"), so I have to move the seat up a fair amount so I can reach the pedals while driving.
The result is that I'm sitting further up then my passenger. not side by side.
Even when the car is sitting still and I'm not in it, the seats look off kilter.
if I could slide the passenger seat forward, I would!

BatmobileS240 · 10-19-2008, 08:42 PM

Because the fire extinguisher is in the way (for those that have one).
