XTRACTABLE SEAT
The seat must be removable without the need to cut any of the seat belts or remove the harness buckle.
The shoulder and lap belts must fall away over the seat edges as it is withdrawn and the crotch straps
must pass freely through the seat bottom hole or holes, which must be located in front of the driver's
crotch.
Any seat liner must have the same holes as the seat shell, identical and perfectly aligned with them in order
to prevent the harness straps being trapped.
However, if the lap straps have to pass through holes in the seat, it is necessary to fit the car with a harness
having the buckle attached to a shoulder belt, given that the buckle will not pass between the driver's body
and the side of the seat.
Pay attention that the extractable seats are not restricted by the crotch seat belt buckles, preventing the
extraction of the seat.
In case the seat doesn’t have the correct (bigger) shape of the hole for the crotch straps, please use the
template available in the share zone to trim the holes in the seat, which allow for correct extraction of the
seat.
An example of the template is reported as follow.
