Definitions
- the invention relates to an assembly of a belt buckle for the tongue of a vehicle seat belt, a mounting bracket for the belt buckle and a force limiter between the buckle and the mounting bracket.
- the stretching element consists of a plurality of annular stretching members which are connected in one piece and which are stretched between the belt buckle and the fastening fitting after a predetermined tensile load has been exceeded.
- the resulting increase in length between the mounting bracket and the buckle limits the maximum force acting in the vehicle seat belt.
- Projection-like limiting elements are arranged in the interior of the annular stretching elements, which come into abutment from a predetermined stretching and thus limit a further increase in the length of the stretching element.
- a disadvantage of this known assembly is that the characteristic curve of length increase over effective tensile force cannot be set independently of the maximum tensile load, the transmission of which is required by the assembly. - 2 -
- the invention provides an assembly of a belt buckle, a mounting bracket and a force limiter, in which the characteristic curve of length increase over effective tensile force can be adapted in any way to the respective requirements, without influencing the maximum allowable tensile load, which is between the buckle and the mounting bracket can be transferred.
- the force limiter contains a traction means which is fixedly connected to the belt buckle and which is movable relative to the fastening fitting by a predetermined path, and a stretching element which is coupled to the belt buckle and the fastening fitting and can be stretched by exceeding a predetermined tensile force between the buckle and the mounting bracket.
- the invention therefore provides, in addition to the stretching element, a separate traction means which serves to transmit a substantial part of the tensile forces acting between the belt buckle and the fastening fitting, at least in the fully extended state of the force limiter.
- the stretching element can therefore be dimensioned independently of the maximum load capacity of the assembly.
- the traction means consists of at least one wire rope, which is fixedly connected to the belt buckle and is displaceably guided on the fastening fitting, and that a stop part is attached to the end of the wire rope facing away from the belt buckle, which, after an adjustment of the wire rope, is relative to the fastening fitting comes into contact with the fastening fitting by the predetermined path. Since a wire rope is particularly well suited for the transmission of tensile loads and can also be used inexpensively, this design allows a module to be obtained with comparatively little effort, with which, despite the existing stretching element, particularly high loads - 3 -
- two wire ropes are used, which are anchored to the frame of the belt buckle, and that the end of the stretching element facing the belt buckle is firmly pressed with the wire ropes.
- the belt buckle can be safely positioned in the desired orientation in the vehicle interior without additional aids.
- the production of the assembly requires a minimal effort with this design, since the wire cables only have to be inserted into the guide on the fastening fitting and then only the end of the stretching element facing the buckle has to be firmly pressed with the wire cables.
- FIG. 1 is a front perspective view of an assembly according to the invention according to a first embodiment
- FIG. 2 is a perspective rear view of an assembly according to the invention according to a second embodiment
- FIG. 3 is a side view of a detail of the assembly shown in Figure 2;
- FIG. 4 is a side view of a detail of an assembly according to a third embodiment. - 4 -
- FIG. 1 is schematically shown an assembly according to a first embodiment of the invention.
- the assembly includes a buckle 10 into which a tongue of a vehicle seat belt system can be inserted and which is coupled to a mounting bracket 12 which serves to attach the assembly to a vehicle (not shown).
- the belt buckle 10 contains in its interior a load-bearing frame (not shown) into which the loads on the seat belt are transmitted when the tongue is inserted. With the load-bearing frame, two wire cables 14, 16 are firmly connected, onto which a stop part 18 is pressed at their end facing away from the buckle 10.
- the mounting bracket 12 is provided with two guide tabs 20, 22 which grip around the wire cables 14, 16.
- a stretching element 24 connects to the end of the fastening fitting 12 provided with the guide tabs 20, 22.
- This consists of two annular, integrally connected stretching members 26, 28, between which, if desired, a predetermined breaking point 30 can be provided.
- At the extension member 28 are two locking tabs 32, 34, which are firmly pressed with the wire cables 14, 16.
- the two locking tabs 32, 34 are designed and pressed with the wire cables 14, 16 so that they can transmit a maximum tensile force from the wire cables into the stretching members 26, 28, which is greater than the force required to stretch the stretching members.
- Fastening fitting 12 are used, only bent so far that they abut the wire cables 14, 16 with a slight pretension; in contrast to the locking tabs 32, 34, the tabs 20, 22 do not ensure that the wire cables 14, 16 are fixed on the fastening fitting 12, but only provide a predetermined frictional force when there is a relative movement between the wire cables 14, 16 and the fastening fitting 12. - 5 -
- a damping sleeve 36 can be arranged on the end of the wire cables 14, 16 facing away from the buckle.
- the first limit force is composed of the force required to stretch the stretching members 26, 28 and the force required to overcome the friction between the tabs 20, 22 and the wire cables 14, 16.
- the stretching members 26, 28 are stretched because they are carried along by the wire cables 14, 16 via the tabs 32, 34, the wire cables 14, 16 through the tabs 20, 22 be pulled through.
- the optionally provided damping sleeve 36 or the stop part 18 comes into contact with the tabs 20, 22, so that the increase in length is limited.
- the tensile force reached at this point represents a second limit force.
- the stretching members 26, 28 are stretched, and either the damping sleeve 36 or the stop part 18 lies against the tabs 20, 22. If the tensile load is increased further, there is no longer an increase in length.
- the characteristic curve of increase in length over acting tensile force can be adjusted in almost any manner by the design of the stretching members 26, 28 and the pretensioning of the tabs 20, 22, without this influencing the maximum tensile force that can be transmitted between the belt buckle 10 and the fastening fitting 12. - 6 -
- FIGS. A second embodiment of the invention is shown schematically in FIGS. This differs from the first embodiment by the use of three extension members 26, 28, 29 instead of two extension members and by the arrangement of the pulling cables 14, 16 in the area of the fastening fitting 12.
- the pulling cables 14, 16 are attached to the fastening fitting 12 by 180 ° deflected so that the stop member 18 is again aligned towards the buckle. Due to the deflection, an adjustment of the wire cables 14, 16 relative to the fastening fitting 12 is opposed by a resistance force which is composed, on the one hand, of loop friction in the region of the fastening fitting 12 and, on the other hand, of the bending stiffness of the wire cables 14, 16.
- the damping sleeve 36 is already at rest both on the stop member 18 and the mounting bracket 12; it dampens the relative movement between the wire cables 14, 16 and the fastening fitting 12 right from the start.
- FIG. 1 A detail of a third embodiment is shown in FIG.
- the third embodiment differs from the second embodiment apart from the lack of a damping sleeve in that the wire cables 14, 16 protrude beyond the stop part 18.
- two tabs 38 are provided which engage around the wire cables 14, 16 in the same way as the tabs 20, 22.
- they either serve only to guide the deflected section of the wire cables or, in addition, to provide a predetermined frictional force which causes a relative displacement between the wire cables 14, 16 and the fastening fitting 12 counteracts.
