Definitions

  • the present invention concerns a safety belt system.
  • the present invention also refers to a belt buckle, a belt reel, a method for a safety b lt system and a usage of separable belt straps in a safety belt system.
  • a person involved in a head-on collision with their vehicle is regarded as being a person moving at a certain speed in a space and this speed must be retarded to zero. This is achieved via force of contact applied to some part of the torso.
  • the amplitude of this force depends partly on the initial speed and partly on the characteristics of the part making contact with the torso. Of course, this is the case if the part is completely stationary when the torso makes contact with it. In a motor vehicle, it is the interior equipment and the seat belt that applies this force to the torso and, normally, the vehicle will not have become completely stationary when the torso makes impact. In other words, the reference points of the force are also in retardation.
  • the retardation of the vehicle occurs through the deformation of its front structure and then takes place at a relatively uniform rate.
  • the person occupying the car will not immediately put a strain on the protection system but will continue to move freely forward in the vehicle for a certain distance.
  • the distance of deformation in the protection system is naturally much shorter than in the front structure, which is why the retardation of the occupant is around twice that of the vehicle.
  • the most optimum situation is when a person is integrated with the vehicle, i.e. sitting fixed to the body. In that case, the person will experience the same retardation as the vehicle.
  • the kinetic energy of the occupant will mainly be absorbed by the deformation of the front structure with some possible minor deformation of the occupant's fixing points in the car. In the latter case, the retardation of the occupant will therefore be reduced by half and consequently so will the forces of contact on the torso.
  • Three-point safety belts are usually used in passenger cars, where two anchor points are arranged on the floor of the vehicle and one anchor point is arranged on the passenger car's so-called B-pillar.
  • the belt comprises a continuous strap, where, after fastening a person in the vehicle seat, the lower part of the belt, also called the lap strap, is arranged over/below the hips.
  • the upper part of the belt also called the shoulder strap, stretches diagonally over the torso from the hip diagonally up over the abdomen and the lower chest, and over the shoulder.
  • Four-point belts are normally being used in motor sports at present due to the high risk of injury and the increasingly higher safety demands. These belts are usually secured with a belt buckle on the upper torso.
  • the discussion made above can be summarised in that there are two main methods of reducing the forces of contact on the torso of an occupant of a vehicle in a collision. Naturally, this will also reduce the risk of injury when the forces of contact are reduced.
  • the first method entails the design of an interior equipment system that will absorb any energy that is exerted on it. This can be energy limiting devices in the seat belts or deformable steering columns.
  • the second method entails the occupant's torso being fixed to the vehicle as rapidly as possible so that the deformation of the front structure can be utilised to absorb kinetic energy. This can be a belt tensioner and, to a certain extent, airbags. This second method is also called the "ride-down" affect.
  • a safety belt strap for vehicle seats that is intended to gather up the diagonal strap (also known as shoulder strap) so that it is not located in an uncomfortable position on the neck or face of the passenger when in motion but is located farther down on the torso.
  • the strap is so arranged that it comes loose from the safety belt so that the diagonal belt can move to a more suitable position from the point of view of crash safety, located higher on the upper torso.
  • the present invention intends to accomplish a safety belt for motor vehicles where a shoulder strap in the belt system in case of a collision moves to a position on the passenger's/driver's upper torso that is better at absorbing energy than its initial position (at normal loads).
  • the object of the invention is to better manage the load on the torso caused by a collision.
  • the present invention also intends to achieve a faster and more efficient solution than conventional designs and eliminate other disadvantages of present technology as described above.
  • Claim 1 concerns a safety belt system for a motor vehicle comprising at least one safety belt strap arranged on a vehicle seat and one belt buckle arranged on the safety belt strap.
  • the safety belt strap comprises at least one lap belt strap and one or more shoulder straps, in which the lap belt strap is partable.
  • the lap belt strap comprises at least two belt straps that can be separated from each other.
  • One advantage of a safety belt system according to the present invention is that as the lap belt strap will separate in case of a collision, the shoulder strap/straps will be located more centrally on the upper torso in case of a collision, whereby the ability of the safety belt system to absorb strain is improved.
  • the passenger's/driver's torso is more rapidly fixed to the vehicle seat, whereby the deformation of the front structure of the vehicle is more efficiently utilised for absorbing kinetic energy.
  • the safety belt system comprises a four-point belt including two separate straps arranged on each side of the driver's seat intended to be coupled with a belt buckle when anchoring a person in the vehicle seat, where the upper free end of each strap has respective anchor points on the upper part of the seat backrest and where the lower free ends of the straps are arranged on anchor points in the lower part of the seat backrest/vehicle seat.
  • An advantage of a four-point belt is that the belt mountings are located closer to the torso of a person occupying the vehicle seat, which provides a better fit of the belt to the body irrespective of the size of the occupant.
  • the safety belt system comprises a partable belt buckle.
  • An advantage of a belt buckle containing devices that are separable relative to each other is such that an upper part of the buckle is released from a lower part of the buckle.
  • the upper and lower parts can be separated, whereby the upper part can be moved and located more centrally with the shoulder strap on the upper torso of a passenger/driver involved in a collision.
  • the present invention comprises a belt tensioner including two halves, one upper and one lower belt reel arranged adjoining each other.
  • the two halves are arranged to move independently, whereby the lower half tensions the lower safety belt lap strap and the upper half of the reel locks to fix the upper lap belt strap.
  • the present invention includes also a belt buckle for a motor vehicle safety belt system, where the safety belt system comprises at least one safety belt strap arranged on a vehicle seat and one belt buckle arranged on the safety belt strap, the safety belt strap includes at least one lap belt strap and one or more shoulder straps, that the lap belt strap comprises at least two belt straps that are separable from each other and that the belt buckle comprises at least two locking devices that are arranged to separate in case of a collision.
  • the present invention includes also a belt reel for a motor vehicle safety belt system, where the safety belt system comprises at least one safety belt strap arranged on a vehicle seat and one belt buckle arranged on the safety belt strap, the safety belt strap includes at least one lap belt strap and one or more shoulder straps, that the lap belt strap comprises at least two belt straps that are separable from each other and that a belt tensioner comprising an upper and lower belt reel is arranged on the safety belt strap.
  • the present invention includes also a method for a motor vehicle safety belt system comprising at least one safety belt strap arranged on a vehicle seat and one belt buckle arranged on the safety belt strap, the safety belt strap includes at least one lap belt strap and one or more shoulder straps, that as a lap belt strap is arranged at least two belt straps that are separable from each other, whereby the separable belt straps are arranged to separate in case of a collision.
  • the present invention comprises also the use of separable belt straps in accordance with the safety belt system or method.
  • fig. 1 A is a front view illustrating a safety belt system arranged on a motor vehicle seat.
  • fig. IB is a front view illustrating a safety belt system arranged on a motor vehicle seat according to fig. 1A, as the belt is arranged in case of a collision.
