Ergonomy: Lumbar support
The lumbar is the region of the spine between the diaphragm and the
pelvis; it supports the most weight and is the most flexible. The
adjustable lumbar mechanisms in seats allow the user to change the seat
back shape in this region to make it more comfortable.
Some car seat systems are set up with an battery-powered automatic
control to adjust how the seat sits in the car.
In suitably equipped cars, seats and mirrors can be adjusted using
electric controls. Some vehicles let the driver save the adjustments in
memory for later recall, with the push of a button.
Most systems allow
users to store more than one set of adjustments. This allows multiple
drivers to store their comfort settings, or a single driver to store
several different occupant positions. Some vehicles associate memorized
settings with a specifically numbered, remotely operated key fob,
resetting a seat to the position associated with that fob when the
vehicle is unlocked.
