Abstract: An actuator device with an actuator cup having a first end and a second end. The actuator cup defines a storage chamber containing a pyrotechnic material to produce gas. The storage chamber also includes a coolant. At least one electrical connection coupled to the first end, the electrical connection in reaction initiating communication with the pyrotechnic material. The second end of the actuator cup includes a concave surface before actuation of the pyrotechnic material and during the actuation of the pyrotechnic material the second end transitions from the concave surface to a convex surface.

Abstract: A steering wheel includes a steering wheel body and a base. The base carrying an inflator and an airbag package, such that the base, the inflator and the airbag package form a first sub-assembly. The base is connected to the steering wheel body at least indirectly via at least one elastic element, such that the sub-assembly can move relative to the steering wheel body in at least one direction so that the whole sub-assembly serves as a vibration damping mass. The steering wheel also includes a cover element with a roof extending over the airbag package, and at least one horn sensor generating a signal when a pressing force exceeding a predefined value is applied to the roof. The cover element is not rigidly connected to the base, such that the sub-assembly can move relative to the steering wheel body under deformation of the elastic element while the cover element does not move relative to the steering wheel body.

Abstract: An actuator assembly that includes an actuator device. The actuator device includes a tubular housing with a first end and a second end, the tubular housing defining a storage chamber containing a pyrotechnic material to produce gas. At least one electrical connection is coupled to the first end, the electrical connection in reaction initiating communication with the pyrotechnic material. An actuator housing that partially encompasses the tubular housing, wherein an outer surface of the actuator housing comprises a hexagon shaped portion that extends along a longitudinal direction of the actuator housing. An assembly housing at least partially encompasses the actuator device, wherein an inner surface of the assembly housing comprises an engaging surface portion that extends along a longitudinal direction of the assembly housing that corresponds to and slidably engages with the hexagon shaped portion of the actuator housing.

Abstract: A method for detecting analytes in flow rate analysis and chromatography is described. The method comprises the following steps: a) providing one or more light sources, an optical wave guide, a container containing a specimen with one or more analytes, and one or more detectors; b) exposing the container containing the specimen to light of one or various, defined wavelengths and/or wavelength ranges; and c) detecting the resulting light waves by one or more detectors after the specimen container is exposed to light of one or various defined wavelengths and/or wavelength ranges, wherein the specimen is irradiated by transferring the light waves through an non-flexible or non-flexibly arranged optical wave guide before the light waves enter the specimen container. The non-flexible or non-flexibly arranged optical wave guide is not susceptible to interference and permits selective irradiation with one or more wavelengths sequentially or simultaneously without requiring much time.

Abstract: A housing for acceptance of an airbag module for a motor vehicle includes at least two side walls located opposite one another formed to be capable of deformation to different extents. The side walls are more easily capable of deformation and exhibit a generally flat area section which can be deformed in the direction of the housing floor if acted upon by force, and which remain stable in shape in the case of tensile force applied in a direction generally away from the housing floor.

Abstract: The invention relates to a housing (1) for acceptance of an airbag module for a motor vehicle, in which at least two side walls (2, 3) located opposite one another are formed so as to be capable of deformation to different extents. In order to fulfil the task set, this housing is characterised by the fact that the side wall which is more easily capable of deformation (3) exhibits a basically flat area section (4) which can be deformed in the direction of housing floor (5) if acted upon by force (F), and which remains stable in shape in case of pull force applied in a direction basically away from housing floor (5).

Abstract: A heating-element in a welding device for heating up plastic molded parts region by region during the welding operation is proposed, comprising at least two shell-shaped heating elements (2, 3) resting on the outside on the plastic molded parts in the region of the weld, the heating elements being of a rotationally symmetrical design, each heating element (2, 3) having a central region (7) and two edge regions (8, 9) arranged adjacently on both sides of the central region in the axial direction and designed in an axially symmetrical manner, and the edge region being formed from a material which has a lower thermal conductivity than the material of the central region.
