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.

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.

Patent number: 5847289Abstract: A rubber-like section with one or several hollow chambers is provided as a sensor receiving section for housing and protecting pressure-actuated sensors, in particular for mounting behind screens and as window guiding sections, in particular for car windows with U-shaped window guiding frames. The design of the mounting space, i.e. the main hollow chamber, allows the sensor to be threaded into the section even over a longer axial distance, to be clamped therein without play and to be firmly held in its mounting position. The inner contour of the main hollow chamber, which is adapted to the sensor use, has a central or eccentric bead-like, heel-shaped projection that extends in the axial direction and projects into the hollow chamber. This geometry allows the sensor housed in the hollow chamber to provide its sensor functions. Other inventions related to the outer geometry of the section result therefrom.Type: GrantFiled: April 24, 1996Date of Patent: December 8, 1998Assignees: Daimler-Benz AG, 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.
