Patent number: 9605993Abstract: A load cell (1) has a deformable body with upper and lower contact surfaces (3, 4), through which a force is introduced. Support points (5) of the contact surfaces define a line of action (6) of the force. At least one column-shaped portion (7) of the deformable body has a central longitudinal axis (8) and a circumferential surface whose generating line runs parallel to the central longitudinal axis (8). A first determining means (9) installed on the column-shaped portion converts a mechanical deformation into an electronic signal, and a second determining means (10) installed on the column-shaped portion converts a deviation of the central longitudinal axis (8) from the line of action (6) into a representative signal. Each determining means has at least one strain gauge.Type: GrantFiled: December 5, 2013Date of Patent: March 28, 2017Assignee: Mettler-Toledo GmbHInventors: Volker Ziebart, Klaus Peter Selig, Urs Loher

Patent number: 6950031Abstract: In order to form a device for detecting and preprocessing weights acting on a vehicle seat in such a way that it can be used in particular in conditions which are very difficult in terms of measuring technology, and in particular under the other special ambient conditions within a vehicle, and the weighing signal of which is substantially uninfluenced by this and can consequently provide a reliable parameter for airbag activation, it is proposed that this device comprises at least three load cells, which are disposed on load-carrying parts of the vehicle seat at corner points of an imaginary polygonal area and in each case generate a weighing signal corresponding to the weight, and an electronic evaluation circuit, which receives and preprocesses the weighing signals of the load cells and generates an output signal based on the weighing signals, the evaluation circuit comprising an evaluation function with which a localization of the center of gravity of the weight acting on the vehicle seat can be carried ouType: GrantFiled: October 31, 2003Date of Patent: September 27, 2005Assignee: Bizerba GmbH & Co.
