Definitions

  • the present invention relates to a connecting part in accordance with the preamble of Claim 1.
  • a connecting part of this kind is known from the American Patent 3. ⁇ 6.533- This connecting part functions as fitting for the safety belt to give in the event of a collision.
  • the connecting part forms the fastening of the safety belt to the vehicle body.
  • the design is such that a continuous groove is made in the coupling piece before accommodating the two wire sections.
  • this groove is of widened design, and the wire sections can be arranged in this widened area with a curved design.
  • a bolt can be accommodated between the wire sections.
  • the wire sections On the side of the wire part remote from the connecting bolt, the wire sections also extend beyond the coupling piece.
  • the wire sections In the event of a collision, once a certain value has been exceeded the wire sections will be displaced with regard to the bolt and, as a result of continuing deformation of the wire sections during movement along the bolt, the belt will be moved forwards slightly, in an extremely slowed manner, such that the impact experienced by the passenger at the end of the movement path of the belt will be decelerated. However, at the end of the displacement of the wire sections, the force will be taken up again by a lengthening of the belt, which is fastened in a conventional manner to the vehicle body.
  • This design is relatively complicated, since in fact two connections to the vehicle body are provided. Moreover, the design with the wire section is relatively long, due to the design in which the wire sections move along the bolt.
  • the object of the present invention is to provide a connecting part of more compact design which both provides a fastening and has the ability to allow a certain displacement of the belt with respect to the vehicle body in the event of collisions.
  • the latter property is particularly important for safety belts, in which the forces which occur during collisions are in the order of magnitude of from 5 KN to 20 KN.
  • the free ends of the wire sections do not extend in line with the wire section which is connected, for example, to a safety belt or holder but rather they are turned through at least 180° along the projection. Moreover, clamping by means of the bolt does not take place between the wire sections which are connected to the holder for a safety belt and the like, but rather using the free end sections which have been turned through at least 180 ° .
  • This arrangement may be designed such that, in the normal state of loading, a degree of play is possible between the wire part and the coupling piece in the direction of the wire part. Moreover, it is possible to provide a space between the coupling piece and the wire part perpendicular to the direction of the wire part.
  • the wire sections may be provided with curves or bends.
  • the provision of such curves or bends, the level of deformation respectively, can provide a means enabling the user of the belt to travel a controlled distance, under load, with respect to the vehicle. In this manner, the extent to which the passenger within the belt is decelerated during a collision is reduced, thus reducing injuries and/or the seriousness thereof. This is particularly important with regard to damage to the neck vertebrae (whiplash) .
  • the design of such curves or bends may vary considerably. Bends with a relatively small radius provide a stronger unit than designs which have bends of relatively large radius. It is essential for a deformation of this kind that the wire part has a substantial diameter, so that plastic deformation is required to remove the curves or bends.
  • the wire part is clamped in the coupling piece solely by means of the bolt.
  • the coupling piece may, for example, consist of a plastic or a light alloy.
  • the characteristics of the deformation are affected, since not only does the wire part become deformed, but in addition it comes loose to a greater or lesser extent from the material in which it is integrally cast. If it is expected to come loose to a considerable extent from the material in which the wire part is integrally cast but complete separation is not desired, it may be useful to connect the wire parts to one another via a further structure. Consideration may be given here to arranging a chain link in the region of the 180° bend.
  • the wire part is formed by one or more cables, the above- described fastening can be achieved, but due to the higher elasticity thereof the above-described plastic deformation will only be possible if it is situated in a different material, as mentioned above.
  • this extension may be designed as a belt guide and as a support for the bolt.
  • that section of the wire, strip or the like which extends outside the coupling part is wound into a spiral.
  • This spiral may be an extension of the limbs of the U- shaped recess, but may also be arranged so as to extend substantially perpendicular thereto.
  • a spiral of this kind provides further damping. It is possible to arrange a safety belt or the like on a spiral of this kind.
  • Fig. 1 shows a top view of a part of a first connecting part according to the invention
  • Fig. 2 shows a perspective view of the coupling piece in accordance with Fig. 1;
  • Fig. 3 shows a top view of a second embodiment of the invention
  • Fig. 4 shows a top view of a third embodiment of the invention
  • Fig. 5 shows a side view, partially in cross-section, of the embodiment in accordance with Fig. 4;
  • Fig. 6 shows a fourth embodiment of the invention
  • Fig. 7 shows a top view of a further embodiment of the invention
  • Fig. 8 shows a top view of an embodiment of the invention in which the wire part is integrally cast
  • Fig. 9 shows a further variant of the connecting part according to the invention, in which the projecting end sections of the wire have been wound into a spiral;
  • Fig. 10 shows a variant of the structure in accordance with Fig. 9.
  • FIG. 11 shows a further embodiment of the structure in accordance with Fig. 9-
  • the connecting part according to the invention is denoted in Fig. 1 overall by 1. It comprises a wire part 2, comprising wire sections 26 and 27. On one side, these wire sections 26 and 27 meet in a bend 28, and on the other side they have free ends 3 ⁇ . These free ends 3 ⁇ re achieved via an at least l8 ⁇ ° bend or first part 16. Moreover, wire sections 26 and 27 are provided with curves or bends 10.
  • Coupling piece 3 is provided with an opening 4 for accommodating both a bolt (cf. also Fig. 5) and the free end sections 34.
  • Projections 9 are present for guiding the bend or first part 16 of the wire section.
  • a cover may be provided for enclosing the wire section 2 in coupling piece 3. or else the unit is fastened against a surface of the vehicle, in order to provide an enclosure.
  • Any other structure which is subjected to tensile loading may be fastened to bend 28.
  • the strength on break was found to approach the strength of the wire part. It will be understood that by changing the thickness of the wire, the design of the form of the bends and also the form of the wire itself, such as round, square, oval, etc., the force-distance characteristic can be influenced. Thus it is possible to provide optimum matching as a function of the application without a fundamentally different structure being required.
  • Fig. 3 depicts a variant of the structure shown in Fig. 1.
  • the connecting part is denoted by 11 and comprises a wire part 12 and coupling piece 13- Free end sections are provided with reference numeral 14.
  • wire part 12 is fastened to a safety belt, only part of which is illustrated, indicated by 15- Curves in wire part 12 are indicated by 20.
  • the first section is again denoted by 16 and adjoins the second part 17.
  • Components corresponding to Figs. 1 and 2 are provided with the same reference numerals.
  • Fig. 4 which is denoted overall by 21, comprises a wire part 22 and coupling piece 23- In this design, this wire part 22 is provided with an extension which is denoted by 24.
  • This arrangement is shown in more detail in Fig. 5 and functions to fasten the adjoining safety belt 25.
  • the bend of the wire part 32 which forms part of connecting part and is accommodated in a coupling piece 33 • is of double structure. It comprises a number of wire loops 35 rotated into one another.
  • the curve or bend used here is denoted by 40.
  • Fig. 7 shows a number of connecting parts 4l according to the invention coupled to one another.
  • Each of the connecting parts comprises a wire part 42 and a coupling part 3-
  • the assembly formed in this way is denoted by 37.
  • Fig. 8 depicts an embodiment of the invention which is denoted overall by 50.
  • the wire part comprises wire sections and 53. which are connected to one another.
  • a chain link 57 is arranged in the region of the 180° bends. If, in this design, a force is exerted on bend 58, firstly bends 5 would come loose from the plastic material, as a result of which a first quantity of energy is absorbed. The bends 56 will then be deformed.
  • the presence of link 57 makes it impossible for the arrangement to break completely free from the bolt (which is not shown in more detail).
  • Fig. 9 illustrates a further variant, in which in particular those sections 62 of the wire which extend outside the connecting part (which is not shown) are important. It can be seen from this figure that the free ends of these sections are wound around a rod 63. In this manner, two spirals 64, 65, which are screwed into one another, are formed.
  • Fig. 10 shows a variant in which there is a single wire part 72, which is wound around rod 73 by two oppositely wound spirals 7 and 75- If a safety belt or the like is fastened to the rod, in the event of loading the spirals 74 and 75 will gradually unwind, so that the weight of the passengers in a vehicle can be taken up in a controlled manner.
  • Fig. 11 shows the wire part in which the wire part is denoted by 82 and is wound by means of two spiral windings (84 and 85) onto a rod 83-
  • the safety belt or other object is fastened in wire section 86.
  • a particularly effective fastening for a safety belt and the like to a vehicle body can be provided by using a wire part in combination with a coupling piece, in which the wire part may optionally be of curved design.
