1. A safety belt arrangement for a motor vehicle, comprising a safety belt, a belt buckle, and a belt tongue;
- at least one sensor region arranged at the safety belt, at the belt buckle and/or at the belt tongue, which includes;
at least one first sensor for determining values of a quantity dependent on a cardiac and/or respiratory activity of a user of the safety belt; and
at least one second sensor for determining values of at least one ambient quantity,and at least one evaluation unit for determining information with respect to the cardiac and/or respiratory activity of the user of the safety belt by using the values determined by the first and second sensors of the sensor region.
