  • Patent number: 6672619
    Abstract: A safety device for use in a motor vehicle includes a restraining element in the form of a net (4) initially stored within a housing (3) extending across the entire upper edge of a windscreen (2). Pull cords (5, 6) attached to the edges of the net extend downwardly past guides (7, 8) located adjacent the lower edges of the windscreen to a centrally located drive mechanism (9). Further pull cords (10, 11) extend from positions more towards the central part of the lower edge of the net, and initially extend around the outer periphery of the windscreen being retained by a yieldable mechanism. The pull cords (10, 11) pass guides (14, 15) located adjacent the lower edge of the windscreen (2) and thus to the drive mechanism (9). The drive mechanism applies such a tension to the pull cords (5, 6, 10, 11) that the net is drawn to a position in which it extends tautly across the windscreen (2) in response to an accident situation.

  • Patent number: 6095585
    Abstract: A cargo floor for use in vehicles including front and rear floor portions with at least the rear floor portion being slidable out of the vehicle, the rear end of the front floor portion including an angled surface and the front end of the rear floor portion including an angled surface such that the forward and rear floor portions are longitudinally displaceable with respect to each other by interaction between these angled surfaces upon application of a forward force to the vehicle such as during a collision, and a joint connecting the forward and rear floor portions whereby the forward floor portion can be slidably moved along with the rearward floor portion and the rearward floor portion can be angularly displaced about the joint.

  • Patent number: 5348342
    Abstract: Apparatus for protecting vehicle occupants during side collision are disclosed, including at least one air bag mounted in a vehicle seat and a sensor for pyrotechnically initiating inflation of the air bag. The sensor is mounted on a frame connected to the vehicle body and on which the vehicle seat is mounted, and the vehicle body's sides and/or doors include compression load transfer plates for the direct transmission of energy to the sensor for bag inflation upon deformation of the corresponding side and/or door of the vehicle body.
