Definitions

  • the invention relates to an occupant restraint system in a motor vehicle with a belt force limiting device according to the preamble of patent claim 1.
  • Passenger restraint systems are now found on most seats in automobiles. They serve to keep the injuries to the occupants as low as possible in the event of an accident in the vehicle.
  • occupant restraint systems with seat belts and so-called airbags are used.
  • a from practice well known airbag is an automatically inflatable in case of an accident the airbag disposed when not in use in a collapsed state in a housing space, for example, behind a lining part in the interior of the "vehicle side in the seat or in the door. Occur From this accommodation space the gas bag is inflated in the event of a critical driving state, in which case the gas bag is briefly inflated by means of a sensor-controlled gas generator, so that a balloon-like protective cushion is formed to protect the occupant.
  • seat belts have long been used in motor vehicles to protect the occupants.
  • Many different types of such seat belts are therefore known.
  • many vehicles are equipped with belts that are on the market, either on two or on three fastening points are arranged in the vehicle, and which are intended to prevent the body of the persons in the vehicle from being displaced as a result of the inertial force in the event of a sudden sharp braking or impact of the vehicle on an obstacle.
  • a method for limiting the restraining force exerted on the occupant in a passenger restraint system by means of a belt is described, for example, in European patent application EP 0 734 922.
  • the restraining force exerted by the belt on the occupant is limited by a force limiter to a level that is adjustable and can be adapted to the body size or the weight of the vehicle occupant.
  • the setting of the force level is carried out in such a way that the characteristic curve has a decreasing tendency in the characteristic curve representing the force over the forward displacement path in the region of a distance, after which the contact between the belt webbing and the inflated restraining element is expected to pass.
  • the force limiter itself is designed such that the restraining force is limited by plastic material deformation and the strength of the material deformation is variable depending on parameters that are representative of the body size or the weight of the occupant.
  • DE 196 04 483 C1 describes a safety device for motor vehicles, a control device connected to sensors being provided for the controlled influencing of the restraint characteristics of the safety device having a seat belt for the occupant in the vehicle within the human tolerable range. This should be set up with a view to the best possible retention characteristics.
  • control device with a blocking device for the belt which has a limited belt extension permitting force limiting means is coupled such that 'depending on from the control device the detected body information about the occupant, the related to the passenger seat position data and / or the Accident-related data of the force curve emanating from the force limiting device and / or the extent of the permitted belt webbing extension is checked, controlled and limited until the belt extension is completely blocked.
  • DE 19604483 Cl describes a belt force limiting device which controls and limits the force curve during a force limiting process. For this purpose, the seat position and body data of an occupant and accident condition data are recorded and evaluated. The initial level of force limitation is set in accordance with the evaluation result and the degressive force level is adjusted by measuring the webbing extension.
  • the seat belt device u described herein further includes a locking device which responds when a predetermined accident severity is exceeded and prevents the seat belt from being unwound further.
  • DE 19951655 AI describes continuously reducing the belt force during the course of the accident, occupant parameters such as weight and position being used as input parameters for determining the degressive belt force curve.
  • the present invention is based on the object of providing an occupant restraint system with limitation of the restraining force exerted on an occupant by a belt, which makes it possible to further reduce the occupant load in the event of an accident.
  • the occupant restraint system according to the invention in a motor vehicle comprises a seat belt with a belt force limiting device in which the level of the restraint force can be changed.
  • the belt force limiting device has at least two restraint force levels, with a shift from a lower restraint force level to a higher restraint force level if it is determined by a hazard determination stage that an occupant is at risk.
  • a determined hazard to an occupant means that the hazard determination level uses the detected parameters to determine that, in the event of an accident, there is a hazard to an occupant due to an impact of the occupant on a vehicle interior component, for example the probability of an occupant's head colliding with a front one Vehicle interior trim, on a display or control element or on the steering wheel exceeds a predetermined threshold.
  • the restraining force level is set in such a way that the occupant load by the belt is as small as possible, an occupant being additionally restrained by the airbag.
  • the deployment state of an airbag is used to determine the hazard to the occupant with regard to an impact on a vehicle interior component. For example, in the case of a multi-stage airbag, which airbag stage is recorded Pf ⁇ PH, C ⁇ d ⁇ -o DJ> ⁇ ⁇ OH ri- ⁇ s: ö CT. P ⁇ rt Cfl ⁇ rt CD H li DJ f Pf d iQ

  • the belt force control stage 14 causes the restraint force level of the belt force limiting device 16 to be increased in the seats on which a hazard was determined.
  • FIG. 2 shows a block diagram of another embodiment of the occupant protection system according to the invention, which enables the restraining force level to be raised during the course of the accident.
  • a seat occupancy detection .3 detects whether a vehicle seat is occupied and transmits this information to the airbag deactivation stage 8.
  • the seat occupancy recognition 3 also detects the occupant weight and transmits the weight information to the hazard determination stage 12. From a Belt webbing extension detection stage 18, the belt webbing extension is detected and an occupant advance during a collision is determined. As an alternative or in addition to this, the occupant advance during a collision is calculated from the deceleration of the vehicle in an occupant advance calculation stage 19 and transmitted to the hazard determination stage 12.
  • the airbag deactivation stage 8 detects the signals of the seat occupancy detection 3 and determines from which seats no airbag deployment should take place. The deactivation stage 8 transmits to the airbag controller 10 which airbags are deactivated and thus are not triggered in the event of a collision.
  • An accident severity detection device 20 detects signals which allow the accident severity / crash intensity to be determined, for example the vehicle speed immediately before the collision or acceleration signals from one or more acceleration sensors in the vehicle. The accident severity determination device 20 determines the severity of the accident from the detected signals and transmits it to the hazard determination stage 12 and the airbag control 10.

Abstract

La présente invention concerne un système de retenue de passager dans une automobile, comprenant une ceinture de sécurité et un dispositif de limitation de force de ceinture, le niveau de la force de retenue pouvant être modifié par un signal de commande. Selon l'invention, le dispositif de limitation de force de ceinture< >(16) est commandé par un signal de commande pour passer alors d'un niveau de force de retenue faible à un niveau de force de retenue plus élevé, lorsqu'une étape de détermination de danger (12) a permis de détecter un danger auquel est exposé le passager, correspondant à un choc possible du passager sur une partie structurelle de l'habitacle du véhicule se trouvant devant lui.
