Abstract

An installation for the height adjustment of the upper anchoring or deflection point for the shoulder belt of a belt system in a vehicle, with individual seats adjustable in the horizontal and/or vertical direction; a transmission installation is thereby interconnected between each seat and the coordinated anchoring or deflection point which during an adjustment of the seat so displaces the anchoring or deflection point that a height position of the anchoring or deflection point is achieved which is favorable for the belt user in relation to the adjusted seat position.

Claims

1. An installation for the height adjustment of a point consisting of one of upper anchoring and deflection point, for a shoulder belt of a belt system in a vehicle, including individual seat means adjustable in at least one of two directions consisting of horizontal and vertical direction, characterized by transmission means operatively interconnected between a respective seat means and said point coordinated to the seat means, said transmission means being operable to displace said point during an adjustment of the seat means such that a height location of said point is realized which is favorable for a belt user in relation to the respective adjusted seat position.

2. An installation according to claim 1, characterized in that the transmission means is operable to be calibrated at least in one base position.

3. An installation according to claim 2, characterized in that the adjustment of the point takes place in a stepwise manner.

4. An installation according to claim 2, characterized in that the adjustment of said point takes place in a stepless manner.

5. An installation according to claim 2, characterized in that an adjusting path of said point to that of the seat means is at a predetermined ratio.

6. An installation according to claim 5, characterized in that the transmission means includes an electrical transmitter mechanism.

7. An installation according to claim 6, characterized in that the electrical transmitter mechanism includes a potentiometer and an adjusting motor operatively connected with said potentiometer.

8. An installation according to claim 5, characterized in that the transmission means is arranged on a side of the seat means, said transmission means includes a hydraulic transmitter and a hydraulic follower operatively connected with said hydraulic transmitter and said point.

9. An installation according to claim 8, characterized in that the hydraulic transmitter is a hydraulic cylinder and a follower cylinder in communication with the hydraulic cylinder.

10. An installation according to claim 5, characterized in that the transmission means includes a flexible connection means for transmitting both tensional and compression forces.

11. An installation according to claim 5, characterized in that a two-armed lever means is supported at the horizontally longitudinally adjustable part of the seat means, one lever arm of said two-armed lever means includes an adjusting rod responding to a seat height adjustment and the other lever arm of the two-armed lever means is operatively connected with one end of the transmission means.

12. An installation according to claim 8, characterized in that a selecting means is provided for enabling an adjustment of the height position of said point starting from a center position without simultaneous adjustment of the seat means.

13. An installation according to claim 1, characterized in that the adjustment of the point takes place in a stepwise manner.

14. An installation according to claim 1, characterized in that the adjustment of said point takes place in a stepless manner.

15. An installation according to claim 1, characterized in that an adjusting path of said point to that of the seat means is at a predetermined ratio.

16. An installation according to claim 1, characterized in that the transmission means includes an electrical transmitter mechanism.

17. An installation according to claim 16, characterized in that the electrical transmitter mechanism includes a potentiometer and an adjusting motor operatively connected with said potentiometer.

18. An installation according to claim 1, characterized in that the transmission means is arranged on a side of the seat means, said transmission means includes a hydraulic transmitter and a hydraulic follower operatively connected with said hydraulic transmitter and said point.

19. An installation according to claim 1, characterized in that the transmission means includes a flexible connection means for transmitting both tensional and compression forces.

20. An installation according to claim 1, characterized in that a two-armed lever means is supported at the longitudinally adjustable part of the seat means, one lever arm of said two-armed lever means includes an adjusting rod responding to a seat height adjustment and the other lever arm of the two-armed lever means is operatively connected with one end of the transmission means.

21. An installation according to claim 20, characterized in that a selecting means is provided for enabling an adjustment of the height position of said point starting from a center position without simultaneous adjustment of the seat means.

22. An installation according to claim 1, characterized in that a selecting means is provided for enabling an adjustment of the height position of said point starting from a center position without simultaneous adjustment of the seat means.
