Car Ergonomics

[VBV]

Hi all,

I had a few thoughts about Car Ergonomics and I've penned them down here. Please feel free to add your thoughts on making drives comfortable and strain free.

Driving a car can be pleasure or a pain, if you do not set the right
seating posture. A good seating posture can eliminate lot of back and neck
related injuries in the longer run. With that in mind, here are a few
factors around the discussion of driving ergonomics.

A. Back rest position:

Most cars will have a tilt-able back rest. This is not just for good
support, but also for comfort. If the back rest is tilted too much to the
front, there is a chance that the lower back will get strained over time.
It also important to sit close to the backrest to get enough support to
lower back or lumbar disc.

B. Seat position:

Seats are moved to and fro, based on the driver's reach. The ideal
position as I am told is that the driver should be able to depress the
clutch fully without stretching or compressing one's legs. A bad seat
position usually leads to strain in knees and calf muscles.

C. Seat height:

Some of the newer cars have adjustable seat heights and that should be
adjusted to give complete support to inner things when the clutch is
pressed. Other factors to consider are wind screen visibility and the
meter visibility. The seat height should also be low enough to allow
atleast a fist of space between the head of the driver and the roof.

D. Steering tilt:
Steering should be tilted to give the driver a good view of the meter and
should be perpendicular to one's fist. The other factors to consider are
the space between the things and the steering wheel. If improper, this
adjustment can cause strain the hand joints.

E. Steering reach:
Some of the cars have a telescopic steering to enable people to pull/push
the wheel from them. The ideal setting is that the hands are not
outreached nor are they compressed. This avoids shoulder strain.

Apart from the above common ones, new innovations are being introduced in cars to help in achieving a better driving experience. Some of them are
lumbar disc support, inner thigh support, seat pan tilt etc., In addition
to the above, there are simple features like a proper head rest, an arm
rest, a dead pedal which have been existing for ages. All of these enable
better ergonomic seating position.

Car Ergonomics is one of the most important points left out by many drivers even when they are behind the wheels !

It can cause you to suffer from back, neck and shoulder pain and can cause cramping and poor circulation in your buttocks and legs. If you are not sat correctly and comfortably, it also has the potential to cause damage to your spine.

Good one. I'am following most of them you have mentioned. Most of the problems will also be caused with the seats itself (in low end cars)

What about the blind spot while driving some cars?? Do they also classify as a part of the car's 'ergonomics'

I wonder why only premium cars like Corolla have lumbar support on the driver seat. After a long drive in my esteem, my back aches very badly and after many adjustments to the seat it still doesnt compare to the comfort of a seat with lumbar support. I wish most cars were equipped with this and also with an arm rest.

H'lo

appreciate that someone has raised this topic. I am short in height ie. 5'7" but have found that while driving the honda city (old & new) I was in total control of the car but in the case of the cielo I was at loss although it had height adjustment.

I term this as driveability of a car.

Hence the cars with good driveability (with/without height adjustment) are :-

1. Honda city both new & old
2. Honda Accord
3. Opel Astra Old
4. Toyota Corolla
5. Octavia
6. Old zen 7. Old Fiat 1100

Cars with low driveability are :-

1. Opel Astra
2.Cielo
3. Palio
4. Accent
5. Esteem.

Prudently I like all the cars I have listed so no bias. I would appreciate if someone could explain this or is it just me.

Cheers and thanks

I think even the ergonomics covers the reach to the controls after adjusting the seating position.

What if you have adjusted the seating position correctly, so that the left leg stretches completely for pressing clutch, but the gear lever is somewhat ahead of reach of left hand.

I have observed in old 2nd gen WagonR (may not be applicable to all people), the steering wheel obstructs the dash indicator views, and everytime to see the dash you have to lean forward.
