Definitions
- the invention relates to a safety belt device for a motor vehicle having the features of the preamble of claim 1.
- a three-point seat belt essentially consists of a diagonal belt running diagonally across the occupant's chest to a second lower point from a first point in the area above the shoulder, and a lap belt crossing the passenger's pelvis from a lower point to a second lateral one Point runs.
- the diagonal belt and the lap belt are each fastened to the motor vehicle with a second end or can be wound up on a belt retractor fastened to the vehicle and are detachably fastened respectively to the motor vehicle with a first end via a belt fastening device.
- the belt fastening device consists of at least one belt buckle fastened to the motor vehicle by means of a belt buckle holder, and at least one belt tongue lockable with the belt buckle, via which a coupling of the diagonal belt and the lap belt to the belt buckle takes place.
- a proven and well-known three-point seat belt device is designed such that a first end of a webbing on a vehicle-mounted belt retractor wound up and a second end of the webbing is attached to a second point of the vehicle.
- On the webbing belt tongue is slidably arranged, which in a third on a ten point arranged buckle is lockable, whereby the webbing is divided over the belt tongue in a pelvic and diagonal belt.
- the object of the present invention to provide a generic seat belt device with which the occupant can be restrained in an accident with a reduced Brückindschreibung without disadvantages to safety.
- a seat belt device for an occupant of a motor vehicle is proposed to solve the problem with:
- the belt fastening device comprises a first locking device for the first end of the lap belt and a second locking means for the first end of the diagonal belt, and the first and the second locking means are coupled together, and the coupling of the first and second locking means can be canceled by an accident triggered movement.
- the advantage of the proposed solution is that the locking devices are coupled during normal use of the seat belt device, so that the ends of the diagonal belt and the lap belt can be fastened to a composite of the locking devices to be considered as an assembly.
- the coupling of the locking devices is lifted only in an accident or in a pre-accident phase, so that the ends of the diagonal belt and the lap belt can then independently perform a movement.
- This freedom of movement of the ends of the lap belt and the diagonal belt causes the belt sections can independently align under the acting belt forces after decoupling in the different directions of force.
- the first end of the diagonal belt held in the first locking device can make a forward movement in the direction of travel, whereby the tensile force in the diagonal belt and thus the breast indentation can be substantially reduced.
- the restraining forces in the lap belt and in the diagonal belt are independent of each other after the decoupling of the locking devices in the direction and in size, whereby they can better perceive the functions assigned to them.
- the term accident-triggered movement should be understood as meaning all movements in the pre-accident phase or during the actual accident phase, which are caused by the forces acting in the accident or in the pre-accident phase or by devices activated in the pre-accident phase or accident phase ,
- first and the second locking device are formed by belt locks, in which the first end of the lap belt and the first end of the diagonal belt can be fixed by means of a belt tongue.
- the use of conventional buckles and belt tongues for fastening the ends is advantageous in that the handling is basically familiar to the occupant and thereby results in a restraint of the occupant, as has been proven in principle.
- the belt tongues are coupled together and the coupling by a triggered in the accident movement can be canceled.
- the belt tongues can be handled as a composite with one hand, so that the buckling process over conventional safety Gurteinrich lines is at least not complicated.
- the belt tongues can be fixed in a predetermined orientation and arrangement to each other, so that the mating process can be simplified in itself. This is particularly advantageous if the locking devices have a specific orientation or arrangement relative to the occupant, which in this case can be taken into account by the orientation or arrangement of the belt tongues relative to one another in the coupled position.
- the handling of the describedgurteinrich device can be further simplified by the locking devices by a common release device together be angiobar.
- the seat belt device can be solved with one hand.
- Tension devices are usually activated in a pre-accident phase or at least in an early phase of the accident to extract existing belt slack from the seat belt.
- the activation of the tensioning device and the resulting decoupling of the locking devices in each case carried out before the onset of forward displacement of the occupant, ie before the increase in the belt forces, so that the lap belt and the diagonal belt are already decoupled at this time.
- the caused by the tensioning device movement a linear displacement movement of the first end of the lap belt or the first end of the diagonal belt, which can be particularly easily used for decoupling the locking devices.
- the end of the diagonal belt or the end of the lap belt is locked in the locking device with a play facilitating a relative movement between the locking devices. Due to the intended play the fixed in the locking device end passes only after carrying out the relative movement in a load-bearing connection with the locking device, so that the entire locking device initially for decoupling an independent of the end of the therein belt section movement until reaching the load-bearing position can perform.
- the locking devices have an outer contour overlapping in the direction of movement, by means of which a pivoting movement of at least one of the locking devices can be forced to one another during the movement of the locking devices relative to one another.
- the relative movement between the locking devices is used due to the overlapping outer contour simultaneously to the triggering of a pivoting movement, whereby the force application angle of the end of the lap belt and / or the end of the diagonal belt can be changed.
- the overlapping outer contour is provided on the locking device of the diagonal belt in a side section extending perpendicular to the direction of travel of the locking device, and the pivoting movement is aligned about a pivot axis arranged horizontally and transversely to the direction of travel of the motor vehicle.
- the locking devices are positively coupled to each other via at least one shear pin, which is dimensioned such that it shears each other for decoupling the locking devices during the relative movement of the locking devices.
- Fig. 1-3 shows a detail of a seat belt device according to the invention with coupled buckles before and after the operation of a
- Fig. 4 - 7 a detail of a seat belt device according to the invention with coupled buckles and additional game a belt tongue.
- FIG. 1 shows a detail of a safety belt device with a first end of a lap belt 17 and a first end of a diagonal belt 16.
- the respectively not shown second end of the lap belt 17 and the diagonal belt 16 is fixed to a vehicle, not shown wound belt retractor.
- the first ends of the lap belt 17 and the diagonal belt 16 are each connected to a belt tongue 1 and 2, which are each defined in a locking device 3 and 4 in the form of a buckle.
- the GurtSchlösser can be seen in view of the top.
- Each buckle has a release device 9 and 10 in the form of a push button and an insertion slot 5 and 6 for a respective locking plate of the belt tongues 1 and 2.
- the release devices 9 and 10 can also be connected to each other, so that both release devices 9 and 10 can be operated with one hand by pressing only one of the release devices 9 or 10.
- a pocket 8 is provided on the outside of the locking device 4, or on the housing of the buckle of the lap belt 17, in which a arranged on the locking device 3 and on the housing of the buckle of the diagonal 16 shear pin 7 with a weaker sheared section 15 form fit engages.
- a fitting part 12 and 19 is also provided, via which the buckles are fastened to fixed fasteners 13 and 18 fastened to the vehicle.
- a laterally projecting claw 11 is provided, against which a protruding from the fitting part 12 fingers 14 and is thereby secured against rotation.
- FIG. 3 the position of the locking devices 3 and 4 can be seen shortly after the activation of a tensioning device (not shown) connected to the holder 13 of the locking device 4.
- the holder 13 was abruptly in the direction of arrow by the activation of the tensioning device S pulled, causing the coupling of the locking devices
- the ends of the lap belt 17 and the diagonal belt 16 can perform independent movements.
- FIGS. 4 to 7 show an alternative embodiment of the invention.
- the belt tongues 20 and 21 of the diagonal belt 34 and of the lap belt 33 are additionally coupled to one another via a shear bolt 32 provided on the belt tongue 21, which engages in a recess 31 of the belt tongue 20.
- a buckle locking devices 23 and 24 each have a latch plate 22 and 25 are provided, which engage in the locked position in an opening 26 or 27 of the belt tongues 20 and 21.
- the belt tongues 20 and 21 are coupled to each other via the shear pin 32 in such a position that between the latch plate 22 and the edge of the opening 26 a clearance is present, that is, the latch plates 22 and 25 during the locking movement of the belt tongues 20 and 21 successively in the openings 26 and 27th
- a tensioning device not shown provided, which pulls the holder 36 in an activation abruptly in the tensioning S.
- the belt tongue 21 is about the latch plate 25 and the shear pin 30 with in
- the buckles in this embodiment have an outer contour with a plurality of projections 28 and recesses 29 which engage with each other and thereby overlap in the direction S of the tensioning movement, so that the movement of the locking device 24 relative to the locking device 23 causes the locking device 23 with the pivoted thereto held end of the diagonal belt 34 in the direction of arrow P.
- the end of the diagonal belt 34 is moved forward in the direction of travel in a position which is more favorable for the occupant load and in particular for the pressure of the chest. Since the locking device 24 of the lap belt 33 does not perform this pivoting movement or is pivoted in the extreme direction in the direction of travel back, the retention function of the lap belt 33 is not changed and in extreme cases even increased, while the restraining force of the diagonal belt 34 is reduced for a lower occupant load.
- the ends of the lap belt 33 and the diagonal belt 34 after the decoupling of the locking devices 23 and 24 perform independent movements, whereby the Gurtabschnit e can perform their function better.
