  • Patent number: 8827356
    Abstract: An inflatable member, or deflector, is attached to the frame of the vehicle. The deflector in the expanded condition at least partially fills a space defined by a bumper beam, a portion of the frame, a front tire and a portion of the vehicle body. A sensor provides a signal to a controller to actuate an inflator. The sensor may be a contact sensor, such as an accelerometer or an electro-resistive sensor, or the sensor may be a predictive sensor, such as a radar sensor or a machine vision sensor.

  • Patent number: 8532881
    Abstract: A connecting device arranged in a motor vehicle releasably connects a structural member of the vehicle to the vehicle chassis and includes a bolt joint system. The connecting device further includes a pyrotechnical charge and an igniter. The igniter detonates the pyrotechnical charge upon receipt of an ignition signal. The pyrotechnical charge is located near the bolt joint system such that, upon detonation, it destroys the connecting function of the bolt joint system and thereby releases the structural member from the chassis.

  • Patent number: 8491008
    Abstract: An inflatable active bolster for a vehicle occupant, the bolster having a first body section and a second body section interconnected by a living hinge. The first and second body sections are folded about the living hinge to form a hollow chamber. The first body section provides an outer surface for facing the vehicle occupant, while the second body section provides a support surface for coupling the inflatable active bolster to a vehicle. At least one of the first and second body sections provides at least one expansible element such that upon pressurization of the hollow chamber, at least a portion of the at least one expansible element undergoes deformation to permit inflation of the hollow chamber, thereby displacing the outer surface of the first body section outwardly to an extended position.

  • Patent number: 8376451
    Abstract: An automotive energy dissipation device includes a bladder disposed adjacent to an interior surface of a body panel of an automobile. A protective liner is disposed between the bladder and the body panel. A valve for inflating the bladder is associated with the bladder. Additionally, a pressure relief valve is associated with the bladder. The automotive energy dissipation device functions when pressure within the bladder exceeding a preset limit attributable to compression during an impact is released through the pressure relief valve. As air exits the pressure relief valve it dissipates energy. This in turn reduces the damage and severity of a crash thereby better protecting the occupants from injury.

  • Patent number: 7768381
    Abstract: A collision detection apparatus for a vehicle having a vehicle bumper, which includes a bumper reinforcement includes a chamber member, a pressure sensor, and a collision detecting device. The chamber member is provided inside the vehicle bumper at a front surface of the bumper reinforcement. The pressure sensor is configured to sense change of pressure in the chamber space. The chamber member includes a deformable part and a non-deformable part, each of which extends in a vehicle width direction. The deformable part is compressed to be deformed between the collision object and the bumper reinforcement in a case, where the collision object collides with the vehicle bumper. The non-deformable part is limited from being compressed to be deformed.

  • Publication number: 20080143146
    Abstract: A system for preventing roof crush during a rollover type automobile accident. The system is a series of shock absorbing elements that are incorporated into each pillar of a vehicle and interconnect to the roof, and an airbag for detaching the roof apart from the vehicle just prior to a rollover event. During the rollover process, but prior to an actual rollover, the airbag deploys to detach the roof, which is supported by the series of shock absorbing elements. In the event that the vehicle completes the rollover or impacts an object or structure, the shock absorbing elements cushion the forces applied to the roof and prevent reduction of the available space of the passenger cabin. The shock absorbing elements also reduce bouncing of the vehicle by non-resiliently absorbing some of the force placed on the roof during a rollover.

  • Patent number: 7350852
    Abstract: An inflatable interior panel for a passenger vehicle includes a non-inflatable section, and an inflatable section having a peripheral portion adjacent the non-inflatable section. The inflatable section is isolated from the non-inflatable section wherein the inflatable section is not in fluid communication with the non-inflatable section. The inflatable section includes a base wall including a slack material section enabling inflation of the inflatable section, and an inboard wall connected to the base wall to define an interior of the inflatable section. When the interior is pressurized the inboard wall is moved away from the base wall to an extended position with respect to the relatively stationary non-inflatable section.
