Abstract

A seat bench device with a seat bench component and at least one restraining unit. the seat bench component comprising a seating surface and a backrest, and the at least one restraining unit comprising a harness for restraining a seat bench occupant on the seat bench component, wherein at least two guide elements are provided and wherein the at least one restraining unit is movably arranged on the at least two guide elements for being movable on the at least two guide elements along the backrest at least between a storage position and an operating position, in which the harness is operational for buckling up of a seat bench occupant.

First claim

What is claimed is:

1. A seat bench device with a seat bench component and a plurality of restraining units, the seat bench component comprising a seating surface and a backrest, and wherein each restraining unit comprises a harness for restraining a seat bench occupant on the seat bench component, wherein at least two guide elements are provided, wherein each restraining unit is movably arranged on the at least two guide elements for being movable on the at least two guide elements along the backrest at least between a storage position and an associated operating position, in which the harness is operational for buckling up of a seat bench occupant.

2. The seat bench device according to claim 1 , wherein at least one first guide element is arranged in a region between the seating surface and the backrest, and that at least one second guide element is arranged in a region of a top end of the backrest.

3. The seat bench device according to claim 2 , wherein at least one first guide element and the at least one second guide element are embodied as linear rods.

4. The seat bench device according to claim 1 , wherein each restraining unit comprises a plurality of slidable attachment units that are glidingly mounted to the at least two guide elements, the harness being mounted to the plurality of slidable attachment units.

5. The seat bench device according to claim 4 , wherein a plurality of locking devices is provided, each locking device being at least adapted for locking an associated one of the plurality of restraining units on at least one of the at least two guide elements in the operating position.

6. The seat bench device according to claim 5 , wherein at least one slidable attachment element of the plurality of slidable attachment units is equipped with an associated one of the plurality of locking devices.

7. The seat bench device according to claim 1 , wherein each restraining unit comprises a folding device that is adapted for maintaining the associated restraining unit at least in the storage position in a folded state.

8. The seat bench device according to claim 7 , wherein the folding device is operable for unfolding the associated restraining unit in the operating position.

9. The seat bench device according to claim 8 , wherein each restraining unit comprises first and second vertical frame members, each frame member having a pair of slidable attachment elements that are glidingly mounted to the at least two guide elements such that the first and second vertical frame members move relative to one another along the at least two guide elements between the storage position and the operating position, the harness being mounted to the first and second vertical frame members by way of the pairs of slidable attachment elements, wherein the folding device comprises a plurality of struttings that are pivotally mounted to the first and second vertical frame members via the slidable attachment elements, the plurality of struttings being rotatable relative to the first and second vertical frame members for unfolding the associated restraining unit.

10. The seat bench device according to claim 1 , wherein a sled device is provided for glidingly mounting the seat bench component to associated supporting stanchions.

11. The seat bench device according to claim 10 , wherein the seat bench component and the at least two guide elements are rigidly mounted to the sled device.

12. The seat bench device according to claim 11 , wherein the sled device comprises an energy absorbing system that is adapted for absorbing energy in a crash situation.

13. A seat bench device comprising:
a seat bench component having a seating surface and a backrest;
first and second guide elements supported by the seat bench component; and
a foldable restraining unit comprising: first and second frame members, and a harness for restraining a seat bench occupant on the seat bench component, the harness being supported by the first and second frame members, wherein each of the first and second frame members are supported for translation on the first and second guide elements along the backrest such that the restraining unit is moveable along the backrest and such that the first and second frame members are moveable relative to one another, wherein the restraining unit is configured to move between (i) a storage position with the first and second frame members adjacent to one another and (ii) an operating position with the first and second frame members spaced apart from one another and with the harness operational for buckling up of a seat bench occupant.

14. The seat bench device of claim 13 wherein the foldable restraining unit further comprises a folding device configured to maintain the restraining unit in each of the storage position and the operational position, wherein the folding device comprises a release hand gear with first and second pins.

15. The seat bench device of claim 14 wherein the foldable restraining unit has a vertical strutting connected to the release hand gear, and first, second, third, and fourth struttings each pivotally mounted to the vertical strutting, wherein the first and second struttings are pivotally supported by first and second ends of the first frame member, respectively, and wherein the third and fourth struttings are pivotally supported by first and second ends of the second frame member, respectively; and
wherein the first and second pins are configured to prevent rotation of at least one of the first, second, third, and fourth struttings to maintain the restraining unit in the storage position.

16. The seat bench device of claim 14 wherein the foldable restraining unit further comprises first and second release levers rotatably supported by the first and second frame members, respectively; and
wherein the first and second pins are configured to be received by first and second openings in the first and second release levers to maintain the restraining unit in the operational position.

17. The seat bench device of claim 16 further comprising a locking device having first and second quick release fittings associated with the first and second release levers, respectively, wherein the locking device is configured to lock the restraining unit with respect to at least one of the first and second guide elements.

18. A seat bench device with a seat bench component and at least one restraining unit, the seat bench component comprising a seating surface and a backrest, and the at least one restraining unit comprising a harness for restraining a seat bench occupant on the seat bench component, wherein at least two guide elements are provided, the at least one restraining unit being movably arranged on the at least two guide elements for being movable on the at least two guide elements along the backrest at least between a storage position and an operating position, in which the harness is operational for buckling up of a seat bench occupant, wherein the at least one restraining unit comprises a head restraining unit.

19. The seat bench device according to claim 18 , wherein one of the at least two guide elements is arranged in a region between the seating surface and the backrest, and wherein another of the at least two guide elements is arranged in a region adjacent to a top end of the backrest.

20. The seat bench device according to claim 18 , wherein a plurality of restraining units is provided, each restraining unit being movably arranged on the at least two guide elements for being movable on the at least two guide elements alo
