Claim:
A vehicle seat occupancy detection device for use with a vehicle seat, comprising: a base frame which can be adjusted in the height direction of the vehicle seat, the base frame arranged between a seat part of the vehicle seat and a vehicle body part and having at least two scissors arms connected to one another; a first detector directly connected to at least one of the scissors arms, the first detector configured to detect a predefinable height position of the at least one scissors arm that is lower than a maximum possible height position when the vehicle seat is occupied by a minimum weight; and at least one spring connected to at least one of the scissors arms, the spring having a predefinable pretensioned spring force that corresponds at most to the downward-acting weight force due to the minimum weight and counteracts the latter, wherein the predefinable height position is only detected by said first detector once said predefinable pretensioned spring force has been overcome.
