Abstract:
A safety restraint system for a vehicle is disclosed. The safety restraint system has a seat belt webbing for restraining an occupant of the vehicle, a seat belt retractor, a deflector, a height adjuster, a latch plate deflector, a buckle and a communication link. The seat belt retractor mounted to a first structural member of the vehicle for securing the seat belt to the vehicle and allowing protraction and retraction of the seat belt. The retractor has at least two load limiting modes. The deflector receives the seat belt webbing and directs the seat belt webbing across the shoulder of the occupant. The height adjuster secures the deflector to a second structural member of the vehicle. The deflector is positionable between at least two locations along the height adjuster. The latch plate deflector receives the seat belt webbing and redirects the seat belt webbing across the lap of the occupant. The buckle receives and removably secures the latch plate deflector when the seat belt is in use by the occupant. The communication link is attached at a first end adjacent the height adjuster and at a second end to the retractor for switching the retractor from at least one load limiting mode to another.
Abstract:
The present invention relates to a new type of gas generant that may be used in airbag inflators. This new type of gas generant is designed to be flexible such that it may be used in side-curtain airbag applications and other situations where flexibility of the gas generant is required or desirable. The gas generant will generally include a flexible igniter, which in some instances, will be an electrical wire. The gas generant also includes one or more beads that are made from a gas-generating material. Each of the beads has a connector passage that is designed such that the flexible igniter may be strung through the connector passage in the beads. In some instances, the connector passage will be a hole in the bead through which the flexible igniter may be passed.
Abstract:
A tether release mechanism for a restraining element of a restraint protection system includes a base, a retention device and an actuator. The retention device is coupled to the base for movement between a locked position and a release position. The restraining element is secured relative to the base in the locked position and is movable relative to the base in the release position. The retention device includes a portion for releasably engaging the restraining element. The actuator is operatively associated with the retention device and is operative for at least initiating movement of the retention device from the locked position to the release position.
Abstract:
A misalignment detection sensor assembly is provided, which includes a forward-looking sensor having a sensing direction along a first axis and an inertia sensor configured to sense acceleration along a second axis, the second axis having a fixed relationship with respect to the first axis. A misalignment detection system uses the misalignment detection sensor assembly and a signal processing system to calculate a misalignment angle between the first axis and the direction of forward motion of the sensor assembly. A method of detecting angular misalignment of a forward-looking sensor assembly is also disclosed, which includes measuring acceleration along an axis having a fixed relationship with respect to the sensing axis of the forward-looking sensor assembly and comparing the acceleration measurement with a predetermined threshold.
Abstract:
Disclosed are embodiments of methods and apparatus relating to automotive airbags. In one embodiment of the invention, an airbag cushion is provided having four primary panels. A front panel is provided having a substantially rectangular front face. Two substantially triangular side faces are positioned opposite from one another in the inflated airbag cushion, both of which are connected with the front panel. A rear panel including an upper rear face and a lower rear face is also provided. The upper rear face is connected to a first side of both the first and second side faces and the lower rear face is connected to a second side of both the first and second side faces.
Abstract:
The present invention relates to a new type of safety system that is designed to protect a vehicle occupant during a rollover crash. The safety system will generally include a vehicle seat and a sensor. The sensor is designed to sense the occurrence of a rollover crash. The safety system also includes a support member that has an undeployed mode and a deployed mode. The support member converts from the undeployed mode into the deployed mode when a signal is received from the sensor indicating a rollover. The support member will generally be housed within the vehicle seat when the support member is in the undeployed mode. The support member is also anchored to the floor pan of the vehicle. When the support member is deployed into the deployed mode, the support member is disposed in effective engagement with the vehicle roof to limit movement of the roof toward the vehicle seat during rollover conditions. Accordingly, the likelihood that the vehicle roof will be collapsed onto the vehicle occupant during a crash is significantly reduced.
Abstract:
An inflatable safety restraint assembly for a vehicle having a front instrument panel and a side pillar. The inflatable safety restraint assembly includes an inflator device and a gas flow control structure connected in gas flow communication to the inflator device to receive inflation gas supplied by the inflator device. The inflatable safety restraint assembly also includes an airbag cushion that is connected in gas flow communication to the gas flow control structure. Upon activation of the inflator device, initial deployment of the airbag cushion occurs from a lower portion of the side pillar. The initial deployment of the airbag cushion occurs in a cross-vehicle direction toward a longitudinal centerline of the vehicle.
Abstract:
A relief valve and related systems and methods are disclosed for use in fluid distribution lines. The relief valve comprises a body defining a cavity and comprising at least first and second openings in fluid communication with the cavity. A connector piece is connected to the body at the first opening to connect the valve to a fluid distribution line. A rupture disc is disposed within and obstructs the first opening. When it is desired that fluid from the fluid distribution line be vented from the system, the rupture disc is punctured and thereby allows for fluid communication through the first opening of the valve.
Abstract:
A device and method for tensioning a vehicle seatbelt are disclosed. The device has a motor, a pulley, a first cable, and a seatbelt buckle. The motor has a motor output for transferring rotational energy developed in the motor. The pulley is in communication with the motor output for receiving the rotational energy developed in the motor. The first cable has first and second ends. The first end is coupled to the pulley. The seatbelt buckle is coupled to the second end of the cable. The rotation of the pulley causes movement of the seatbelt buckle.
Abstract:
A safety device for use in an automobile that comprises a bolster and a telescoping mechanism. The telescoping mechanism extends when pressurized by the rapid introduction of a fluid. Following extension, the telescoping mechanism vents the fluid to allow the device to be retracted.
