Seat Belts
Three-point retracting seat belts are located
at all five seats in the Touareg. The belt lock
and the belt limit stop are located in the
seat. The height of the belt can be
mechanically adjusted at all outer seats. An
electric belt height adjuster and a comfort
mechanism for the front seats is available
as an option.
Ball seat belt tensioner
and belt tension limiter
Ball seat belt tensioners are used at all
four outer seats. They are pyrotechnically
activated.
The driver and front passenger seat belts
have belt tension limiters.
With tension limiters, the belts are at first
tensioned during a collision to optimize the
position of the occupant in the seat.
After a certain belt force has been attained,
the belt relaxes a bit. This provides another
way of reducing the amount of collision
energy transferred to the vehicle occupant.
Belt-use detection
There is a belt-use detection system for the
driver and the front passenger. It ensures
that a warning signal sounds if the driver
does not use the seat belt when operating
the vehicle.
Along with the comfort mechanism, the
belt-use detection system is used to
determine which spring of the comfort
mechanism is used. When the belt latch is
engaged, a soft spring provides comfort to
the occupant wearing it. When the belt
latch is released, the belt rolls up quickly
and safely using a more rigid spring.
