<C Three-point seat belt arrangement in motor vehicles ^

The innovation relates to a three-point seat belt arrangement in motor vehicles, which when opening the The vehicle door automatically enables entry and exit and also turns around automatically when the door is closed the vehicle occupant or around the seat, with two fixed points on the inside of the seat or on the roof or on the vehicle floor and a releasable third fastening point that can be displaced in a guide along the door

Several so-called passive belt systems are known to him, their common disadvantage is the high manufacturing and assembly costs. In a known security belt arrangement of the type mentioned at the beginning, for example, the door

»Either end of the belt moved out of the area of the entrance opening by means of an electric motor. This means one relatively high technical and cost-related effort.

According to another proposed passive belt system, in which the detachable belt attachment point in the form of a Slide is longitudinally displaceable on the roof frame above the door, this effort is reduced in that ^ ur When the slide is actuated, the mechanical work performed during the door movement is directly used.

Another seat belt arrangement of the aforementioned Type that also uses the energy provided by the door movement to move the detachable belt attachment point British patent 1,215,424.

The translation of the door movement into the desired slide movement for the purpose of loosening or putting on the belt arrangement takes place in both cases mentioned by relatively complicated lever or cable systems «,

The task of the present innovation is to implement the Door movement into the required movement of the detachable belt fastening point can be achieved with even simpler means.

digits and thus the cost and susceptibility to failure to further reduce or to significantly increase the functional reliability of a belt system of the type mentioned. The innovation solves this problem by such an arrangement and design of the guide, since "the between the guide and the one emanating from the detachable belt attachment point Belt end resulting angle for every door position is smaller than 90 ° and furthermore by the fact that the detachable » Attachment point forming strap! ill supply spring funds to retract the same into its operative position at the rear lower end of the door.

The innovation enables the door movement to be implemented immediately detachable belt strap in the desired movement

Festignngpunkt ^ s accomplished along its leadership. This inevitable sliding of the door-side belt fastening :: ^v , "and thus the automatic release of entry b ^ v. Exit is made possible by the opening and closing of the

C Fehrze: agtür occurring change in distance between the door and seat (or belt fastenings in the middle of the car) through a Belt defined in its length up to the door is used. Elaborate and failure-prone lever or cable pull systems can be omitted.

"ar mentioned angle below 90 ° is in general already then achieved when the guide runs parallel to the door wall.

7211SM * 8; iU3

In an advantageous development for the effect of the innovation, it can be improved by the fact that the "guide runs obliquely in such a way that the front end of the guide xcshr in the direction of the vehicle lies towards the center of the vehicle than the rear end.

In addition, it is useful to train the leadership in such a way that that they are from one at the front more after the vehicle ykitto to the lying part and a rear part to the outside and these two straight and parallel mutually extending parts merge into one another in an arc.

For the practical realization of the. According to the idea of innovation, an embodiment is preferred which is characterized in that an automatic ^{belt A} winding device is arranged at the rear lower end of the door, from which a belt extends, which is attached to a detachable belt attachment point in a manner known per se forming, in the guide: slidable carriage attached loop passes through and is guided from there to a buckle and shoulder belt unifying buckle and that a limiting device is provided to limit the distance between the guide carriage and the buckle. The automatic belt winder takes over the function of the detachable belt part when it rides from it

Belt attachment point engaging spring means.

In order to ensure that the \ 4vJjT », which is pulled out of the winding device, continuously glides through during the opening process of the door. «» € jL jlS ZU νδ ~ ϋ1Πΰ.θΐ "Π USu viciuvuTCh © jTSt CtI. 6 ge WUIi sä CiVb ΰ

To enable carriage movement along the guide, it is proposed according to the innovation that as a limiting device a rope attached on the one hand to the eyelet of the guide carriage, on the other hand to the belt buckle, serves its Length corresponds to the maximum allowable distance between the relevant parts.

According to another embodiment of the innovation, this can Rope to be replaced by that as a limiting device on the part of the belt extending from the automatic belt winder between the belt lock and the guide slide eye a local thickening is provided which is larger than the opening of the guide carriage eyelet

Another variant in this regard is characterized in that exn cable pull as a limiting device on the belt lock is attached, which passes through a second arranged on the guide carriage eyelet and with its other end on attacking the front lower part of the door · In contrast to the two aforementioned embodiments, however, remains here the distance between the eyelet and the belt closed during the door

Bevregungsvorgances is not constaut, but is through the Attachment of the cable to the door and deflection of the same on the carriage so variable that it is variable with increasing door opening angle gets bigger. This advantageously results in less friction when moving the slide, because the angle mentioned can be kept smaller by increasing the distance between the slide and the belt buckle. aside from that This arrangement makes it possible to move the slide into the guide even with a small door opening angle move forward.

Of course, you can increase the friction in this way. reduce that instead of the usual in a guide groove guided sliding piece as a guide carriage guided on a rail or in a guide groove on roller bearings Guide part serves

According to another feature of the innovation, will be alternative proposed to the above-described handling of the distance slide / belt lock that as a limiting device on front lower part of the door a cable is attached to the passes through a second eyelet on the guide carriage, from there to another eyelet attached to the belt lock and after redirection through this back to the second eyelet on the guide carriage and is attached there. As a result, the belt movement of the system can advantageously vary in installation conditions be adjusted.

According to Fig. 1 to 3, 10 denotes the driver's seat of a passenger vehicle, 11 the backrest and 12 the headrest of the seat 10. 13 is the left front door of the vehicle. The entry threshold is indicated at 14. The seat 10 is assigned a three-point seat belt system, which consists of a Pelvic belt 15 and a shoulder belt 16 consists. Pelvic and Shoulder belt 15, 16 are formed by a coherent belt strap, which is from a fixed point 17 on the vehicle floor 18 takes its exit, from one on a seat belt buckle 19 known design attached eyelet 20 is deflected and

finally on the side of the copy support 12 in its second Fixed point 21 opens, which is of course also provided on the roof or on a correspondingly designed auxiliary carrier can be.

The belt lock 19 is attached to the end of a belt 22, which proceeds from an automatic belt winding device 23 attached to the rear lower corner of the door, the Wiγα of which is generally known and therefore does not need to be explained again here.

In the door 13 a guide 24 is incorporated, in which a Slide 25 is arranged displaceably. The carriage 25 has an eyelet 26 through which the belt 22 passes. The essence of the invention is now to be seen in the fact that the possible distance between eyelet 20 and buckle 19 and the carriage 25 (or eyelet 26) is limited, for example in this embodiment by a rope 27, which one- " on the one hand on the buckle 19, on the other hand attached to the eyelet 26 is. The rope 27 replaces the electric motor required in known passive safety belt systems or the above Mentioned elaborate mechanics with cables or levers.

Wound 23, the carriage 25 with the eyelet 26 is located esa lower end of the guide rail 24 "The rope 27 between the buckle 19 and eyelet 26 is relaxed. Fig. 3 shows schematically the top view of seat IO and door 13, the latter being in different open positions. The designations from FIGS. 1 and 2 have been adopted and supplemented by indices A to E according to the various opening positions of the door 13 shown. When the door is opened (closed), the lap belt 15A and shoulder belt 16A wrap around the backrest 11 as a result of the tensile force of the automatic roller 23. The rope 27A between eyelets 20A and 26A is relaxed, the carriage 25A is at the left end of the guide rail 24. In door position B (opening the door) the belt 22B is pulled out of the roller 23. The rope 27B is now tensioned. With further opening up to door position G. the slide 25C, pulled by the rope 27C in the guide 24, slips forward, while the belt 22C is pulled further out of the roller 23. In the door position D, the belts 16D and 15D now lift off the backrest 11, since the carriage 25D, pulled through 27D, slides on. In the door position E, which at the same time represent the largest opening angle of the door 13, the slide 25E has now slipped into its front end position as a result of the pull from the cable 27E. When pulled through the eyelet 26E, the belts 15E, 16E and 22E - as shown in FIG. 1 - release entry (or exit).

For the movement when closing the door 13, the door positions are to be considered in the order E to A. The inevitable sliding of the carriage 25 in the guide 24 is achieved when the here z. Be angle F shown in position C between guide 24 and belt part 28 of belt 22C or rope 27C is smaller than 90 °. This fclgt according to a further feature of the invention that "the .just in Fig. 3 in plan view drawn guide 24 may also be curved so r-, for example, mentioned angle F daö as small as possible and thus the friction is low. Also is it within the scope of the invention to use a roller-mounted guide part as a slide 25 instead of the slide shown.

Fig. 4 to 6 show an embodiment similar to Fig. 1 to 3, but here on the use of the Ent learning between the eyelets 20 and 26 limiting rope 27 is dispensed with by a local thickening 29 of the belt 22 of this at ¹ range a certain extension length from the automatic roller 23 moves the carriage 25 when the door 13 is opened further.

From FIGS. 7 to 9, further variants of the inevitable Guri / movement when opening the vehicle door 13 can be seen. These Embodiment differs from that according to Fig.

is not attached to the guide eye 26, but afc. you z. B. is deflected by a second eyelet 31 and is preferably attached to the door 13 f au the lower front corner 32. 8 shows the belt lock 19 with the door 13 partially open. The rope 30, like the rope 27 in iig * 1 to 3, determines the distance between the belt lock 19 and the eyelet 26 and thus causes the slide 25 to be displaced in the guide 24 when the door is moved.

The main difference to the embodiments according to Fig. 1 to 3 or 4 to 6 ordered here, however, that during the door or carriage movement, the distance between eyelet 23 and belt lock 19 does not remain constant. Much more the distance is so variable due to the attachment of the rope 30 at 32 or by the UmlenJeung of the same at 31, that it becomes larger with increasing door opening angle, since the length dtes with 33 (Fig. 8 and 9) designated section de3 rope 30 increases accordingly. This will be beneficial a lower friction achieved during the displacement of the carriage 25 because of the extension described of the Seilabschnitfces 33 the mentioned angle F (Fig. 3) can be kept particularly small. In addition, »I result

9 shows the belt arrangement according to FIGS. 7 and 8 with the door 13 fully open. The section 33 of the cable 30 has now its greatest length. In addition, with reference to Fig. 9 illustrates yet another variant, how with the help of a Cable 30, 33 a certain distance between the parts 26, 19 can be maintained. The Z. B. in Figs. 7 and 8 shown rope 30 can be arranged according to this further feature of the invention so that it is from its door side Attachment 32 through the loop 31 to the belt lock Ϊ9 runs, but not there, as fastened in FIGS. 7 and 8, but is deflected again at 34, runs back to the slide 25 and is attached here or on the eyelet 31. As a result, the length of the rope section 33, i. H. the removal of 19 to 26, to be halved in order to adapt the belt movement of the system advantageously to different installation conditions.

Furthermore, it is also possible to limit the length of the cable section 33 by an arrangement similar to FIGS. 4 to 6 so that that the rope 30 can slide through the eyelet 31 up to the door position in FIG. 8, for example. If the Door 13 would then be a slide 25 corresponding to the in 1 to 3 move manner shown. By combining the

The passive belt arrangement shown can thus advantageously achieve a desired belt movement when opening the door 13 Ö! * Z Ϊ. € i JL S21 λ.

In Fig. 10 the door 13 is in the open position. The guide 24 runs here obliquely to the door wall, in such a way that the front end of the guide 24 lies further towards the center of the vehicle than the rear end. It is thereby achieved that the angle r F (see Fig. 3) between the guide 24 and belt member 28 is even smaller. The slide 25 moves even more easily in the guide 24. The slide 25 is is Fi *** - 10 Z ¹ JXZ For better sliding in ucji "Fuux-ÜJLts 24 with Köliöju. 40 Vcx ~ £ St? Ueu. The the remaining parts in Fig. 10 correspond to those in the other figures.

11 shows a guide 24, the partial sections 42, 44 of which are located towards the ends, straight and at a distance from one another run, with the front part 44 in turn being more towards the passenger compartment than the rear part 42. The parts 42 and 44 merge into one another with an arcuate section 46. This training of the guide 24 takes into account the fact that the angle F between the guide and the belt part 28 in general when opening the Door is small, then enlarges and becomes smaller again when the door is opened at a large angle. One from the back \

The end of the curve is slightly curved towards the passenger compartment Guide track 24 can also already be advantageous with regard to the angle F.

According to a further feature of the innovation, the guide rail is so arranged that it has its length when the door is opened changed relative to the door. In Fig. 12 this is achieved by the guide rail 50 with its rear end 52 at

r 53 is rotatably mounted, while at its front end 54 it is articulated at 55 with a guide piece 56 which runs in a sliding guide 57. The sliding guide 57 is attached to the side of the dashboard 58, for example. When the door 13 is closed (position A), the guide rail 50 lies within the door. The guide piece 56 connected to the guide rail 50 via the hinge 55 is located at the right end of the sliding guide 57. In position B of the door 13, the guide rail 50 has rotated a little out of the door at a point 53 because the guide

\ piece 56 in the sliding guide 57 has shifted to the left. Finally, in position C, the sliding piece 56 has moved to the left end of the sliding guide and the guide rail 50 has moved further out of the door. It can easily be seen that in the position C of the door 13, the angle F (FIG. 3) between the guide rail and the belt part 28 not shown in FIG. 12 is smaller than in the arrangement in FIG.

rail always runs parallel to the door. In the arrangement according to FIG. 12, therefore, the moves for the sake of simplicity not shown and designated in Fig. 3 with 25 carriage easier in the guide rail 50, so dak the opening of the A slight resistance is opposed to the door ·.

The angle F ¹ can be even more favorable in the arrangement according to FIG. The movement of the articulation point 55 can proceed in an expedient manner in accordance with the curve 59.

Fig. 13 shows a further embodiment of the Guide rail 50, this is now with its front end over an extension 52 to a lever arm 63 in the point hinged. The lever arm 63 is movably mounted on an angle piece 65, which is suitably attached to the Karosja ^ rie is attached. As can be seen, this angle piece also serves as a bearing point 66 for the door 13. The guide rail 50 is firmly connected with its rear end to the door 13 ^ As the point 68, the guide rail 50 is either articulated or it consists of such a elastic material that it moves out of the door at this point or from this point when the door is opened. As can be seen, the angle F between the guide rail 50 and the is not bsi the position C of the door 13
