Abstract:
A device for triggering an airbag device that is accommodated in a steering wheel is described. The device has a firing cap for an airbag device that is accommodated in a steering wheel and is fired by a light pulse that is supplied via an optical waveguide. A coupling device, which decouples the optical waveguide from the rotation of the steering wheel but ensures that the light pulse is transmitted into the firing cap from the optical waveguide and also ensures that the airbag is inflated by a gas generator, is provided between the optical waveguide and the airbag.
Abstract:
A system for measuring the weight of a seat occupant is used to control airbag deployment. The system is incorporated into a vehicle seat supported on inboard and outboard track assemblies. The inboard and outboard track assemblies are mounted to a vehicle structure such that a center track portion remains unsupported. A first sensor assembly is mounted to the inboard track assembly and a second sensor assembly is mounted to the outboard track assembly. The first sensor assembly generates a first signal in response to measuring deflection of the inboard track assembly due to seat occupant weight. The second sensor assembly generates a second signal in response to measuring deflection of the outboard track assembly due to seat occupant weight. A central processor determines seat occupant weight based on the first and second signals. The central processor communicates with the airbag system to control the deployment of the airbag based on seat occupant weight.
Abstract:
A detonator device for tripping a passenger restraint device in a motor vehicle includes a detonator circuit on a holder. Firing pins for receiving a detonator element are an integral component of the holder.
Abstract:
A traffic accident detecting sensor for a passenger protection system in a vehicle includes a low-retentivity seismic mass which can move along a guide member between two extreme positions and is normally held in a first extreme position by a contact pressure. The contact pressure is overcome in the event of deceleration in such a way that the seismic mass then moves toward a second extreme position. A magnet being distinct from the seismic mass has a magnetic field which is deformed to a varying degree by the seismic mass depending on the position of the seismic mass. At least one contact can be controlled by the magnetic field of the magnet. The contact and the seismic mass have such a configuration that in the first extreme position the latter to a large extent constitutes a magnetic shunt diverting the magnetic field away from the contact toward the seismic mass so that the contact is then in its first contact state. The seismic mass does not constitute a magnetic shunt at points distant from the extreme position, so that the contact is then controlled in its other contact state under the effect of the magnetic field. The magnet forms the guide member or is rigidly connected to the guide member. The magnet is magnetized perpendicularly to the direction in which the seismic mass can move. The contact is disposed near a frontal surface of the guide member in such a way that the magnetic flux through the contact depends on the position of the seismic mass.
Abstract:
An optical module has a circuit carrier, a housed semiconductor element disposed on the circuit carrier, and a lens unit for projecting electromagnetic radiation onto the semiconductor element. The lens unit preferably includes a lens assembly with, say, three lenses and a diaphragm. The lenses, optionally together with the diaphragm, are aligned in a well-defined manner due to their geometric design so that no additional optical adjustment is necessary. The lenses are held in a type of lens holder that is an integral component of the housing of the semiconductor element.
Abstract:
An optical module has a circuit carrier, a housed semiconductor element placed on the circuit carrier, and a lens unit for projecting electromagnetic radiation onto the semiconductor element. The lens unit, which is constructed separate from the cased semiconductor element, preferably comprises a lens assembly formed of, for example, three lenses and of a diaphragm. The three lenses, optionally together with the diaphragm, are aligned in a well-defined manner due to their geometric design so that no additional optical adjustment is necessary. According to the invention, a support is formed, at least in sections, on the case of the semiconductor element, and the lens unit is placed thereon thus being supported. The concept is that by forming a support directly on the case of a cased semiconductor element even with classically cased semiconductor chips, it is possible to construct a camera module with which every mechanical focus setting can be eliminated. The novel system is particularly suited for use in the interior or exterior of a motor vehicle.
Abstract:
A waterproof housing with a plug-and-socket connection for protecting electronic circuits includes a hard plastic upper part and a hard plastic lower part. A soft plastic extruded seal is disposed between the upper part and the lower part. A plug part is constructed in one piece with the upper or lower part. The plug part has a hard plastic inner part containing contact pins and a soft plastic sealing collar surrounding the inner part.
Abstract:
A housing includes a housing section made of hard thermoplastic material for a circuit, e.g. a motor vehicle locking system, to be protected from harmful substances, and at least one pressure member being made of soft thermoplastic material and being accessible from outside the housing. Each pressure member serves to operate at least one electric switch being disposed or to be disposed inside the housing. Edges of the pressure member provide an all-round watertight and adhesive-free cover for a hole in the housing section, with the edges being injection molded directly onto the synthetic material of the housing section in such a way that the synthetic material of the pressure member and the synthetic material of the housing section are fused together.
Abstract:
In order to provide a simple connection between a shield housing and a strip body, the shield housing, which has resilient side parts with spring arms being bent inwards, is pushed over lead-in and sliding inclines on the strip body and automatically latches on an insertion side or front thereof. The spring arms of each side part, which are located alongside one another, alternately form contact elements providing contact between the shield housing and a mounting panel and sliding and latching elements for connecting the shield housing to the strip body. The invention is suitable for motor vehicle filter plug connectors.
Abstract:
A pressure sensor of a pressure-sensor module is connected to a wet space in a vehicle door by a through-passage channel of a sealing cushion and a connecting branch, which is guided with sealing action through a partition. A housing of the sensor module is located in a dry space. An interior of the housing and the dry space are sealed in relation to the interior of the connecting branch, with the result that a water-tightness of the housing, in which a printed circuit board and electronic components are accommodated, does not have to meet high requirements.
