Patent number: 6685221Abstract: A system for stopping the deployment of an airbag in a vehicle includes a detector for detecting a position of the airbag with respect to an occupant of the vehicle and an airbag operating device. The detector is located on the airbag in an area which, upon deployment of the airbag, is facing the occupant of the vehicle. The detector generates a position signal which is sent to the airbag operating device such that the airbag operating device stops the deployment of the airbag when the position signal indicates a predetermined position of the airbag in relation to the occupant.Type: GrantFiled: December 11, 2001Date of Patent: February 3, 2004Assignee: I.E.E.

Patent number: 6505521Abstract: The invention provides a testable foil pressure sensor constructed of two carrier foils which are laminated together. The first carrier foil is coated with a semiconductor material, while the second carrier foil has two adjacent strip conductors which can each be bonded on both ends and which, within spatially bounded areas which form sensor elements, have “comb” structures, with individual fingers which mesh with one another in a no-contact manner. According to the invention, within a sensor element, at least one of the contact fingers of the comb structure is formed by a strip conductor loop and at least one other contact finger is formed by a stub line branching off a strip conductor.Type: GrantFiled: September 8, 1997Date of Patent: January 14, 2003Assignees: DaimlerChrysler AG, I.E.E. - International Electronics S.a.r.L.Inventors: Volker Petri, Reinhold Mickeler, Michael Meyer, Bogdan Serban, Michel Witte

Patent number: 6373005Abstract: A device for detection of trapping in a power-operated closing element with a switching element, which is arranged along a first closing edge within an elastic hollow section. The hollow section includes a central area extending longitudinally, in which an active area of the switching element is arranged, and at least one side area extending longitudinally, in which a non-active edge area of the switching element is arranged. The side area has a higher deformability on the side of the hollow section facing the first closing edge than on the central area. The device has a force transmitter extending longitudinally, which transmits a trapping force from the side facing away from the first closing edge to the side area of the hollow section.Type: GrantFiled: March 10, 1999Date of Patent: April 16, 2002Assignees: I.E.E. International Electronics & Engineering, S.A.R.L., Daimler-Benz AGInventors: Peter Griesbach, Hans Gamerdinger, Volker Petri, Reinhold Mickeler, Michel Witte, Roland Lorig, Stefan Schmitt

Patent number: 6348663Abstract: The invention concerns a method for determining several parameters of a seated person, comprising the following steps: subdividing the seat surface (4) into at least two sections, determining the barycenter position of the active weight in each section, and evaluating said parameters of said person based on said determined positions. The evaluation of said parameters can include the evaluation of the size and/or weight of said person, the evaluation of the position of the said person on said seat based on the distribution of the barycenter positions on the seat or the evaluation of the orientation of said person on said seat based on the longitudinal positions of the barycenters of the active weight in each section.Type: GrantFiled: July 23, 1999Date of Patent: February 19, 2002Assignee: I.E.E.

Publication number: 20010013203Abstract: An anti-trapping device is described for a power-operated closing element (4) with a switching element (32) which is arranged along a first closing edge (22) within an elastic hollow section (10), and a power transmitter (16), which abuts against a side area (28) of the hollow section (10) extending longitudinally, so that a trapping force (F) is transmitted to the side area (28) of the hollow section (10). The hollow section comprises a central area (26) extending longitudinally, in which an active area (34) of the switching element (32) is arranged, whereas a non-active edge area of the switching element (32) is arranged in the side area (28). The side area (28) is more deformable on the side of the hollow section facing away from the first closing edge (22) than the central area (26).Type: ApplicationFiled: August 3, 1998Publication date: August 16, 2001Inventors: PETER GRIESBACH, HANS GAMERDINGER, VOLKER PETRI, REINHOLD MICKELER, MICHEL WITTE, ROLAND LORIG, STEFAN SCHMITT

Patent number: 6223467Abstract: A motor vehicle sensor arrangement which is used to detect jamming, i.e, an obstruction, at a movable vehicle part which can be moved into an end position, such as an electric window, a sliding and tilting roof, a convertible top, or a servo-actuated door. A cavity defined by opposing resilient walls is located proximate, but outside, the path of movement of the movable vehicle part and at a selected distance from the end position. A distance sensor, for example a pressure transducer, is arranged in the cavity between the resilient walls. When an object obstructs the path of movement of the movable vehicle part toward the end position, the resilient walls are moved toward each other. When the distance sensor contacts a portion of the opposing resilient wall, the distance sensor actuates a response signal indicating a jam.Type: GrantFiled: February 18, 1997Date of Patent: May 1, 2001Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Josef Mahalek, Bogdan Serban, Michel Witte

Patent number: 5851026Abstract: A system to detect certain parameters concerning an auxiliary child seat placed on a passenger seat of a motor vehicle equipped with an airbag protection system. The system uses inductive electromagnetic emitter, inductive electromagnetic receiver, and resonant circuits to detect various parameters concerning the child seat. Some of the parameters include the presence of a child seat, the orientation of the child seat, and the type of child seat present. These parameters are transmitted to an airbag control unit for adapting the deployment of the airbag to the specific circumstances as indicated by the inductive and resonant circuits. The transmitted information allows the airbag control unit to disable the airbag in certain situations where it is not needed.Type: GrantFiled: March 26, 1997Date of Patent: December 22, 1998Assignee: I.E.E.

Patent number: 5618056Abstract: A system to detect certain parameters concerning an auxiliary child seat placed on a passenger seat of a motor vehicle equipped with an airbag protection system. The system uses inductive electromagnetic emitter and receiver circuits located in the passenger seat and at least two resonant circuits provided in the base of an auxiliary child seat. Using the inductive and resonant circuits, the system detects various parameters concerning the child seat. Some of the parameters include the presence of a child seat, whether or not the child seat is occupied, the orientation of the child seat, and the type of child seat present. These parameters are transmitted to an airbag control unit in order to adapt the deployment of the airbag to the specific circumstances as indicated by the inductive and resonant circuits.Type: GrantFiled: October 16, 1995Date of Patent: April 8, 1997Assignee: I.E.E.
