BRIEF SUMMARY
BACKGROUND OF THE INVENTION

The present invention relates to a passive belt system for a motor vehicle which is attached by an automatic roller at the edge of a side door opening and on the seat in the middle of the vehicle and runs over a deflection element arranged at the door post allowing the length to be adjusted in the shoulder area.
A passive belt system for a motor vehicle is already known, as in, for example, German Offenlegungsschrift No. 2,643,818. In this system, there is an extension which runs along the upper door opening to the rear door post. When the strap is not in use, it is placed on the extension thereby remaining at the chest level of the passenger. Disadvantageously, when the strap is in use, it is moved vertically near the head of the passenger.


SUMMARY OF THE INVENTION

Accordingly, it is an object of the present invention to provide a seat belt system wherein the seat belt does not come into contact with the head of the vehicle occupant when being placed in position or removed.
Yet another object of the present invention is to provide a diagonal safety belt which, when removed automatically from the vehicle occupant, is first moved obliquely in a forward and upward direction toward the upper end region of the front door post and is finally arranged along the upper door opening by the displacement of the deflection elements in the direction of the wrist brace.
Advantageously, contact of the belt with the head of the vehicle occupant is avoided when the safety belt is removed either in an oblique forward and upward direction or in the reverse direction.


BRIEF DESCRIPTION OF THE DRAWING

These and other objects, features and advantages of the present invention will become more apparent from the following description when taken in connection with the accompanying drawings which show, for the purposes of illustration only, one embodiment in accordance with the present invention, and wherein:
FIG. 1 is a schematic diagram of a passive safety belt system in accordance with the present invention, some parts shown in section;
FIG. 2 illustrates the path of the safety belt either after attachment or prior to removal of the belt;
FIG. 3 illustrates the path of the safety belt when the switch is activated;
FIG. 4 illustrates the path of the safety belt at the point when the desired door opening is reached.


DESCRIPTION OF THE INVENTION

Referring now to the drawings wherein like reference numerals are used to designate like parts, FIG. 1 shows a diagonal safety belt 6 on the vehicle chassis 2 which can be moved along the upper edge of a door opening 3 of a front side door 4 by means of a device 5 which is essentially controlled by the motions of the side door. The safety belt 6 is affixed in the generally mid plane of the vehicle to a seat 7 by means of a lock 8 and runs to an automatic roller 11 which is arranged in the rear door post 9 via a deflection element 10. The deflection element 10 is arranged at the shoulder height of the vehicle occupant on the rear door post 9 such that the height can be adjusted. The deflection element 10 is a conventional continuous brace. The device 5 features a transport cable 14 along the door opening 3 which is delineated by the rear door post 9, the upper wrist brace 12 and the front door post 13. The transport cable 14 is preferably a flexible toothed rack which is directed through a tube which is slit lengthwise. The transport cable 14 interacts with an electrical drive (not shown) which is controlled by switches (not shown) activated by the motions of the side door 4.
FIG. 1 shows a carrier 15 arranged at the safety belt 6 between the lock 8 and the deflection element 10 and connected so that it can glide along with the safety belt 6. The carrier 15 is connected solidly with the transport or conveying cable 14 by means of a cable 16 which has a constant length. As FIG. 1 also shows the deflection element 10 is connected with a slide 17 which is arranged so that it can be moved in a guide 18. The guide 18 is extended from the shoulder height region
