Abstract: A new and useful belt-tensioning device for an occupant restraint is provided, designed to tension a belt (102) about an occupant at the onset of a vehicle collision, and to provide a measure of controlled force dissipation as the occupant loads the belt during the collision. In a preferred form, a tensioning member (122) moves in one direction (124) to tighten a belt about a vehicle occupant at the onset of a collision, and a braking device (130a, 130b) is configured to apply a controlled braking force to movement of the tensioning member in the opposite direction after the tensioning member has tightened the belt about the vehicle occupant. An array of braking members (130a, 130b) applies different levels of braking force to movement of the tensioning member in the opposite direction, thereby providing controlled braking force to movement of the tensioning member in the opposite direction.

Abstract: An airbag system for a motor vehicle has an airbag that is deployed upon inflation with a gas from a folded state into the vehicle interior. An inflation device supplies gas for inflating the airbag. A sensing device senses deployment of the airbag to the effect that the temporal and spatial sequence involved in opening the folds of the airbag is detected. A control device controls the inflation process as a function of deployment sensing.

Abstract: A calibration spring tension adjuster for a seat belt tension sensor has a calibration spring, and a holder. The fixed part and the movable part are adjacent to each other and comprise mutually facing stepped helical faces arranged so that the movable part can be rotated relative to the fixed part causing the steps to slide over each other causing a gap between the stepped faces to increase and compressing the spring. The steps can be arranged so that movement of the movable part in one direction is resisted. The holder is arranged to attach to the fixed part and the spring is held between an abutment face of the holder and a non-stepped face of the movable part.

Abstract: A device for measuring tensile stress acting on a vehicle seat belt has two components. A first component is connected with a seat belt and a second component is fixed to a vehicle part a spring arranged between the two components, against whose force the two components may be moved relative to one another. A transducer has transducer elements that are attached to the two components and produces an electrical signal as a function of the positions of the two components relative to one another. The transducer produces a switching signal when the components are in a first positional zone. In a second positional zone, in which the two components may be moved relative to one another against the force of the spring, the transducer produces measuring signals proportional to the movement of the two components relative to one another.

Abstract: A seat belt retractor has a spool mounted for rotation in the retractor for retraction or pay-out of seat belt webbing depending upon the direction of rotation of the spool. A locking ring is attached to one end of the spool. A device for locking locks the locking ring against rotation in a crash. A force limiting device allowing further pay-out of the seat belt webbing after the locking ring has locked, under the influence of a vehicle occupant's forward momentum. The force limiting device has a length of wire, attached at one end to one of the spool or the locking ring, and wound, at a distance spaced from said one end, on a pin fixed to the other end of the spool or the locking ring. Under the influence of crash forces above a predetermined value the wire is pulled around the pin.

Abstract: The airbag module has a base plate, two inflators, a top plate and two airbags. The inflators are mounted into the base plate and the airbags are secured to the base plate via top plates. The first airbag has substantially an “L” cross section in its deployed state. The second airbag is adjacent to the first airbag and while both bags are deployed, there is substantially no gap between the first and second airbags.

Abstract: The folding apparatus includes a ram apparatus movable through the tube and adapted to hold and move a ram plate and air bag through the tube. When moved in one direction, the ram apparatus moves the air bag into the cover. The folding apparatus further contains a movable piston which functions as an interior cushion support and is passed through a hole in the air bag module cover. The folding apparatus additionally includes a holding fixture for orienting the cover so that its internal cavity is in alignment with and adjacent to the tube such that the housing and air bag can be rammed into the cover internal cavity.

Abstract: A seat belt retractor for a seat belt system in a motor vehicle has a belt reel for the winding and unwinding of seat belt webbing. At least one locking element can lock the belt reel against further rotation. Forces exerted by the seat belt webbing can be introduced into a frame connected to the vehicle. The locking device has at least one gear that can be locked by at least one lock operating device and also has at least one energy absorbing device.

Abstract: An airbag module has at least two housing parts securely connected to each other by a mechanical catch connection. At least one catch hook is arranged on the first housing part and at least one tab with a corresponding catch opening is arranged in the second housing part. During the latching together of the two housing parts, the catch hook engages the corresponding catch opening. At least one ramp is arranged on the first housing part, opposite the catch hook, which ramp rises in the insertion direction of the second housing. The ramp rises in the direction in which the second housing part is moved toward the first housing part during assembly. During the assembly of the first housing part with the second housing part, the tab of the second housing part comes into contact with the ramp during the latching and is deflected by the ramp in the direction of the catch hook. The deflection of the tab results in the catch opening being deflected or pushed in the direction of the catch hook.

Abstract: A method of manufacturing motor car steering wheels with an external shell made of composite materials, which comprises preparing a pile of sheets of composite materials, hot molding thereof for obtaining respective half-shells with a shape corresponding to that of respective halves of the steering wheel being manufactured, mechanical flattening of the front surfaces of the two half-shells, applying the two half-shells to opposite parts of a steering wheel body formed by a metallic core covered by resin, and mutual fixing of the two half-shells along said front surfaces. After flattening, the front surfaces of the two half-shells are mechanically worked to form respective complementary teeth which can be male-female coupled when the two half-shells are applied around the steering wheel body.

Abstract: The implementation of dual-stage inflators in some production vehicles is quickly becoming a common reality. A dual-stage inflator has two firing squibs that can fire independently, simultaneously or in a delayed mode. This tailorability provides the ability to fire a low level, high level or staged delay level depending on the impact velocity or other means. For each restraint condition, the inflator output threshold speeds are identified. A biomechanical gray zone, for each injury assessment reference value, is defined based on occupant performance. The upper and lower bound of each biomechanical gray zone is associated with a type of occupant, inflator output, belt restraint and injury parameter.

Abstract: 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.

Abstract: A seat belt retractor has a web sensor with an inertia member, a locking pawl and a lock cup. The inertia member is eccentrically pivotally mounted to the lock cup. The locking pawl is integrally formed with the inertia member. The lock cup has a set of radially inwardly pointing teeth for engaging with the locking pawl. The shape and profile of the locking pawl complements the shape of the teeth. The web sensor aids in resisting jamming of the seat belt retractor.
