  • Patent number: 6273455
    Abstract: A textile material blank is proposed for the manufacture of an air bag for air bag modules to be installed in vehicles as an impact protection device for vehicle occupants. The airbag module has an airbag carrier. The blank has one or more connecting flaps (1), either formed integrally with the blank (2) or attached to it, for the purpose of attaching the air bag to the airbag carrier.

  • Patent number: 6247723
    Abstract: A horn switch on a vehicle includes an actuator (1) connected to the steering wheel via webs (2) resiliently deflectable transversely to said steering wheel axis. The actuator is normally spaced from a contact foil and, when actuated, urges on the contact foil to establish an electrical contact between opposed contact areas of the foil.

  • Patent number: 5988675
    Abstract: An airbag module for the passenger side of a vehicle with a diffusor pipe, a gas generator accommodated in and connected to the diffusor pipe, a folded-together air sack accommodated outside of and fastened to the diffusor pipe, a holder around the air sack, and cover components tensioned between a flange at one end of the gas generator or of a generator disk and the ends of the diffusor pipe and securely tensioning the edges of a loop that fits over the diffusor pipe and secures the air sack. The air sack around the holder essentially comprises a sack-like pouch of textile material around the diffusor pipe with two partly overlapping pieces attached to and detachable from each other and concealing the opening that the unfolding air sack emerges through.

  • Patent number: 5944340
    Abstract: The invention concerns an airbag module for the passenger seat in a motor vehicle. The module is characterized by a cylindrical compressed-gas reservoir (1), a tube (2) that encloses the reservoir (1) and has gas-outlet openings (3) distributed along it, two lateral components (4) that are stamped out of sheetmetal and can be forced together along with the tube (2) by the compressed-gas reservoir (1), and an air sack (5) that is provided with a section enclosing the tube (2), that is secured to the tube (2) by means similar to tensioning straps, and that is folded over the tube (2).

  • Patent number: 5901976
    Abstract: A lid (1) for an airbag accommodated in the instrument panel of a motor vehicle. For economy and simplicity of manufacture it is made of a relatively hard plastic. It is characterized in that it comprises a lower layer (2) of soft and resilient plastic and an outer layer (3) of hard plastic and in that both layers (2 & 3) are essentially fastened together adhering totally surface to surface. The outer layer (3) can be made of a plastic that matches the material of the surface of the instrument panel in appearance, feel, and acoustics.

  • Patent number: 5820158
    Abstract: A module for installing a passenger airbag, having a trough-like housing (1). The housing essentially comprises a U-shaped base (2) and two essentially flat ends (3). The module also includes a gas generator (4) and a gas sack (5). The gas sack is folded into the housing over the gas generator, One marginal section (6) of the gas sack (5) is wrapped outward around the edge (7) of the housing (1) all the way around. The marginal section (6) is looped along the base (2) around connecting rods (8). The connecting rods secure the ends (3) to the base (2) and extend within a groove-like inward-opening depression (9) in the base (2). A continuous tensioning band (10) attaches the marginal section (6) of the gas sack (5) to the outside of the housing (1) between the edge (7) of the housing and the connecting rods (8), constituting a force-application attachment.

  • Patent number: 5820159
    Abstract: An assembly for manufacturing an airbag module for the passenger seat in a motor vehicle having a tubular element that accommodates a cylindrical reservoir of compressed gas and two identically shaped frontal components in the form of segments of extruded section that can be forced like hose clips against the tubular element such as to laterally demarcate space for accommodating a folded airbag against the tubular element. The upper area of the frontal components in one embodiment is openwork. Auxiliary tubes can be tensioned between the frontal components. A web of material that wraps around the tubular element can be secured to the auxiliary tubes, laterally demarcating the space for accommodating the airbag paralleling the axis of the tubular element.

  • Patent number: 5813707
    Abstract: To accommodate a gas generator of an airbag for front-seat passenger protection in a motor vehicle, a trough-like housing is proposed which has a constant U-shaped cross section on its length, and flat sidewalls at its ends, which is characterized by two half shells of substantially mirror-image configuration made by casting in a mold with integrally attached side wall halves and by joining the two half shells. The manufacturing method to be applied according to the invention permits flexible adaption of the trough-like housing both to local space requirements and to functional requirements. The housing is especially light and can be made very inexpensively.

  • Patent number: 5735542
    Abstract: A housing for a passenger protection device in a motor vehicle having an airbag and a gas generator therein and a protective covering thereon to form a ready to install module. The housing comprises a body having an essentially U-shaped cross section which is uniform lengthwise along an axis. The housing also has two mainly flat end covers and tension members for simultaneously fastening the airbag and the protective covering to the housing.
