摘要： A vehicle seat belt system is provided. The vehicle seat belt system includes a seat belt comprising a tubular seat belt webbing defining a passageway and a plurality of pressure control valves and a seat belt buckle for connecting to the seat belt. The seat belt buckle has an air delivery port for delivering air to the passenger, and an air delivery device supplies air to the seat belt, wherein the valves allow the supplied air to exit the seat belt at a first air pressure and block air from exiting at a second pressure.

摘要： In a movement damping apparatus, a magnetorheological fluid is pressed through a flow path. A device generating a variable magnetic field comprises a core around which a coil is wound as well as pole surfaces in the flow path, the magnetic field acting on the magnetorheological fluid by way of said pole surfaces. The coil is arranged within the flow path along with the core, the axis of the coil extending perpendicular to the direction of flow of the magnetorheological fluid. The flow path has a jacket made of a magnetically conducting material.

摘要： A seat belt retractor for a vehicle seat belt has a belt reel for the seat belt. A free-flowing load limiting medium is arranged in a working chamber. A displacement means is drivable by the belt reel. The load limiting medium is transported through at least one flow channel by the displacement means. The flow cross-section in the flow channel is selected as a function of the kinematic viscosity of the load limiting medium, to achieve a belt force limitation profile over time which approaches that of a torque rod.

摘要： A seatbelt retractor is operably coupled to a belt dereeling retarder mechanism which utilizes a magnetorheological fluid and a coil for imposing a magnetic field on the fluid to selectively change the fluid properties and a braking or retarding effect imposed on the belt retractor during dereeling or payout of the belt. The retarder may include a piston coupled to a rotatable shaft coupled to the belt retractor reel and displacing fluid through the magnetic field in response to actuation of the belt. Alternate embodiments include a multiple disc brake coupled to the retractor reel through a gear drive speed increaser or a cylindrical housing and core member defining an annular space occupied by the magnetorheological fluid and connected to the belt retractor reel through a speed increasing gear drive.

摘要： A seat belt system for restraining movement of an occupant of a vehicle includes a seat belt and a member having an opening through which the seat belt extends. A first inflatable portion of the seat belt extends in a first direction from the member. A second inflatable portion of the seat belt extends in a second direction from the member. A source of inflation fluid is connected in fluid communication with one of the first and second inflatable portions of the seat belt and connected in fluid communication with another of the first and second inflatable portions of the seat belt through the member. The one inflatable portion of the seat belt enables inflation fluid to flow from the source of inflation fluid into the one inflatable portion of the seat belt and to flow from the one inflatable portion of the seat belt through the member into the another inflatable portion of the seat belt.

摘要： A safety belt retractor, especially in vehicles, is provided that includes a belt shaft as a carrier for a belt that is wound thereon and a vehicle sensitive and/or belt sensitive controllable block device for the belt shaft. The block device includes a force limiting device, effective in the event of a block event, the force limiting device having a viscous medium-filled housing with at least one fixedly positioned contour and a counter-contour that is rotatably displaceable in response to a block event, so that the relative movement between the contour and the counter-contour forces the viscous medium between the surfaces arranged for this purpose. The level of the force limitation applied by the force limitation device is adjustably settable as a function of the parameters associated with the buckled-in passengers via a variation of the inner pressure in the viscous medium-filled housing.

摘要： A seat belt retractor has a belt reel rotatably mounted in a frame. A blocking means blocks rotation of a blockable part of the belt reel and a belt webbing carrier on the belt reel that is substantially drum-shaped. The belt webbing carrier is associated with a rotor that is in rotary drive connection with the belt webbing carrier. Upon rotation of the rotor the volumes of at least two chambers filled with a free-flowing medium are varied, and the chambers rotate about the axis of rotation of the belt reels. The free-flowing medium flows in each case from a chamber diminishing in volume into a chamber increasing in volume.

摘要： The seat belt module is electronically controlled using magneto-rheological fluid. A CPU delivers a signal to an electromagnetic coil within the module at the beginning of a crash to cause the viscosity of the magneto-rheological fluid to increase sufficient to lock the spool on which the seat belt is wound against rotation. Thereafter, a subsequent signal is delivered by the CPU to the coil to reduce the magnetic field and the viscosity of the magneto-rheological fluid allowing the spool to be unwound in a programmed manner so as to reduce the forces imposed on an occupant by the seat belt. The CPU may be pre-programmed in response to signals from sensors throughout the vehicle that deliver signals corresponding to the characteristics of the occupant and may be programmed in response to signals from these sensors and from an air bag to respond in real time.
