Abstract

The invention relates to a load detection unit having a spring-elastic load carrier assembly for receiving the load (10) and a sensor (3) for the deformation of the load carrier assembly, which occurs under the load (10) that is to be detected, wherein a deformation transmission unit (6) is operatively arranged between the load carrier assembly and the sensor (3). A method, in which additionally a deformation transmission unit is used, is thus provided, which during operation picks up the deformation of the load carrier assembly and transmits it to the sensor as a changed force/path load.
