Patent number: 9453927Abstract: A sensor structure includes a substrate having a main extension plane, a first seismic mass and a second seismic mass, the first and the second seismic masses being deflectable relative to the substrate along a direction of deflection essentially perpendicular to the main extension plane. The first and second seismic masses are coupled together via a rigid coupling rocker pivotable around a rocker axis parallel to the main extension plane. The first seismic mass is suspended from the substrate with the aid of a first suspension spring, and an essentially rigid first coupling bar is situated between the first suspension spring and the first seismic mass.Type: GrantFiled: December 28, 2012Date of Patent: September 27, 2016Assignee: ROBERT BOSCH GMBHInventors: Markus Heitz, Christoph Gauger, Sebastian Gracki, Patrick Wellner

Patent number: 9206033Abstract: A micromechanical component including a mass structure which may be deflected with respect to a substrate with the aid of at least one spiral spring in a direction of deflection. The spiral spring includes at least one folding section, which is formed by two spring legs which are situated essentially in parallel to each other and are connected to each other with the aid of a connecting bar. A damping device for oscillating movements of the folding section in the direction of deflection is provided in the area of the connecting bar.Type: GrantFiled: May 24, 2012Date of Patent: December 8, 2015Assignee: ROBERT BOSCH GMBHInventors: Christoph Gauger, Markus Heitz

Patent number: 7730783Abstract: An acceleration sensor includes a seismic mass which is suspended on springs above a substrate and is deflectable in a direction perpendicular to a surface of the substrate. In order to reduce deflections of the seismic mass along the surface of the substrate because of interference accelerations, which lead to a falsification of the measurements of the deflection of the seismic mass perpendicular to the surface of the substrate, the springs include two bending bars which are interconnected via crosspieces.Type: GrantFiled: November 13, 2007Date of Patent: June 8, 2010Assignee: Robert Bosch GmbHInventors: Johannes Classen, Markus Heitz, Lars Tebje, Fouad Bennini
