A device for venting a gas bag made of a textile material includes at least one ignitable pyrotechnic charge which is associated with the gas bag in such a way that, when the pyrotechnic charge is ignited, at least one thread of the textile material is directly destroyed by the explosion of the pyrotechnic charge.

Controlled deflation device for a gas bag

A description is given of a passenger detector comprising a flexible support of insulating material, at least two electrode structures placed on said insulating substrate at a certain distance from each other, and a layer of semiconducting material placed above said electrode structures in an active zone of the detector. In conformity with the invention, said layer of semiconducting material has an internal resistance that varies with a deformation of said layer and said layer of semiconducting material is placed in intimate contact with said electrode structures.

A device for deflating a gas bag includes a gas bag having a deflation opening which is closed along a breakable, predetermined line. The predetermined breaking line includes a closure element and is breakable by melting or sublimating the closure element.

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.

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 &ldquo;comb&rdquo; 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.

Foil pressure sensor which can be tested

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.

Jamming-detection device

The invention concerns a method for determining several parameters of a seated person, comprising the following steps: subdividing the seat surface ( ) 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.

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. Preferably the distance sensor is mounted on one of the resilient walls approximately facing the direction in which the movable vehicle part moves toward the end position, while a projection extending toward the distance sensor is provided on the opposite resilient wall. The projection substantially reduces the travel distance to actuate the jamming signal, since the distance between the distance sensor and the projection is substantially shorter than the distance between the two opposing resilient walls.

Motor vehicle sensor arrangement for detecting jamming

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.

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. The transmitted information allows the airbag control unit to disable the airbag in certain situations where it is not needed, such as when the child seat is not occupied or is facing the rear of the vehicle.
