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; as the top equipment option,
an electric belt height adjustor and a comfort
mechanism are available for the front seats.
Belt use detection
There is a belt-use detection system for the driver
and the front passenger. In ensures that a
warning signal is issued if the driver does not use
the seat belt when operating the vehicle.
Ball seat belt tensioner and belt tension limiter
Ball seat belt tensioners are used at all four outer
seats. They are pyrotechnically ignited.
In addition, the driver and front passenger belts
have belt tension limiters.
Due to the latter, the belts are at first tensioned
during a collision to provide early binding of the
passengers to the vehicle structure.
After a certain belt force has been attained,
the belt relaxes a bit.
This provides another way of reducing
the collision energy.
In co-operation with the comfort mechanism,
the belt-use detection system is used to
determine which spring of the comfort
mechanism is used: When the belt lock is closed,
a soft spring provides high belt comfort.
If the belt is released, it rolls up quickly and
safely due to a more rigid spring.
