  • Publication number: 20090033080
    Abstract: An inflatable air-bag is disclosed which is provided with a controllable vent formed in the fabric of the air-bag. The vent comprises a hole formed in the fabric of the air-bag and a flexible vent tube which extends inwardly of the air-bag from the hole so as to terminate in an open free-end located within the air-bag. The free end of the vent tube is normally tethered within the air-bag so as to maintain the vent in a closed condition but is releasable in response to a signal so as to open the vent. In one arrangement the vent tube is fixed to the inner surface of the air-bag around the hole and is configured so as to have a tapering cross-section which is smaller at the free-end of the tube then at the fixed end of the tube. In another arrangement the vent tube is fixed to the inner surface of the air-bag fabric around the vent hole by stitching which runs around the periphery of the hole and which is located within the vent tube.

  • Patent number: 7484763
    Abstract: The inventive device for fixing a seat belt winder is fixed to the part of a motor vehicle. The plate of the housing of the winder is provided with at lest one fixing hole for receiving a screw connection which maintains the vehicle part embodied therein. The housing of said seat belt winder is arranged in such a way that it is rotatable with respect to the fixing hole of the vehicle part, thereby enabling the winder to be automatically oriented in a direction of a force of a belt which moves at an angle with respect to the axis of the shaft. Said fixing device is characterised in that the housing (10) of the winder is rotationally maintained on the holder part (13, 19, 25) which can be firmly connected to the vehicle part (40).

  • Publication number: 20090020989
    Abstract: An airbag unit with an airbag exhibiting an impact surface, a housing, a gas generator, a first tensioning element extending from housing to impact surface, which is interrupted when the airbag is fully expanded, and a second tensioning element extending from impact surface to an outlet valve with variable cross section located in airbag. The cross section of the outlet valve becomes smaller when the second tensioning element is under tension. In order to ensure a high degree of functional reliability, outlet valve exhibits a nozzle extending around an opening, around which the second tensioning element is guided.

  • Patent number: 7478836
    Abstract: A seat-belt arrangement including an energy-absorbing force limiter. A first component, for example in the form of a retractor reel spool is movable relative to a second component, for example the frame-work of the retractor. The spool carries with it elements presenting friction faces which co-operate with further elements carried by the frame. A stack of Piezo-electric elements apply a compressional force driving together the elements having the friction faces to provide a controlled frictional energy-absorbing effect.

  • Publication number: 20090001786
    Abstract: A recliner mechanism for a vehicle seat includes a support plate (7) mounted on the squab (2) of the seat, and a support plate (11) mounted on the back rest (3) of the seat. There is a pivotal interconnection (10) between the plates to enable the back rest to be reclined. The pivotal interconnection is initially retained by a spring (20), in a retaining part (15) of an elongate slot (14). When the back rest (3) is subjected to a rearward force, such as by a seat occupant in a rear impact situation, the spring is deformed and the pivot shaft moves along the slot (14), enabling the back rest (3) to move rearwardly. An energy absorbing element (17) is provided which deforms, whilst absorbing energy, during this second movement of the back rest.

  • Patent number: 7464962
    Abstract: A novel safety device for the driver's cabin of a truck, wherein the driver's cabin demonstrates at least one driver seat (10, 16) with a first side (10a) facing a side window and a second side (10b) opposite the first side, is suggested. The safety device comprises a safety net (20), which is spread next to the second side (10b) of the driver seat (10) at least in the event of a rollover accident. The safety net can be permanently spread next to the driver seat, or it can be rolled up or folded together in the state of rest and only be spread next to the driver seat when needed. The safety net prevents the person sitting on the driver seat from falling to the opposite inner structure of the driver's cabin when the driver's cabin rolls over (FIG. 10).

  • Patent number: 7431340
    Abstract: A main controlling section of a controlling unit (13), when judging a collision risk, drives a motor (12) in a direction of retracting a seat belt (3) and raises tension of the seat belt (3). The main controlling section, when tension of the seat belt (3) reaches a predetermined value, judges that a locking signal is input and has the motor (12) continue retracting driving of the seat belt (3) for a predetermined time and, when a locking signal is not input, decreases a driving power of the motor (12) and lowers tension of the seat belt (3). Even when a collision risk signal is erroneously output from a collision risk judging section (11) and, so long as a locking signal is not output from the locking signal producing section (18), since control is immediately exerted so that tension of the seat belt (3) is lowered, it is possible to avoid an unpleasant feeling to a vehicle occupant (A) caused by comparative long-duration and useless restraining using the seat belt (3).
