Abstract

A vehicle seat, in particular a passenger seat for a bus, includes a seat member with a seat upholstery carrier and seat upholstery, which is rigidly arranged on the seat upholstery carrier; the vehicle seat also includes a backrest with a back upholstery carrier and back upholstery, which is rigidly arranged on the back upholstery carrier; and a support structure for receiving forces which act on the vehicle seat. The support structure is constructed as a rigid carrier frame arranged at the peripheral side outside the seat member and the backrest and which is connected to the seat upholstery carrier and the back upholstery carrier. The carrier frame has carrier rails which are arranged in pairs and which extend along opposing lateral edges of the seat member and the backrest.

First claim

The invention claimed is:

1. A vehicle seat, comprising:
a seat member having a seat upholstery carrier and seat upholstery, which is rigidly arranged on the seat upholstery carrier;
a backrest having a back upholstery carrier and back upholstery, which is rigidly arranged on the back upholstery carrier;
a support structure for receiving forces which act on the vehicle seat, the support structure being formed as a rigid carrier frame arranged at a peripheral side outside the seat member and the backrest and connected to the seat upholstery carrier and the back upholstery carrier, and the carrier frame being a closed frame having carrier rails arranged in pairs and which extend along opposing lateral edges of the seat member and the backrest, an upper end region horizontal rail connecting upper ends of the carrier rails, and a lower end region horizontal rail connecting lower ends of the carrier rails, and the carrier frame being constructed as a hollow structure; wherein the backrest is adjustable in terms of inclination relative to the carrier frame; and
a headrest rigidly connected to the carrier frame at the upper end region horizontal rail, wherein the vehicle seat is movable from an upper seat position into a lower seat position by adjusting the inclination of the backrest, such that the backrest covers a part-region of an inner face of the headrest in the upper seat position and in the lower seat position the part-region is exposed, and wherein the headrest has lateral sight screens for forming a lateral headrest and visually separating an adjacent person.

2. The vehicle seat according to claim 1 , wherein the vehicle seat is a passenger seat for a bus.

3. The vehicle seat according to claim 1 , wherein at least one of the seat upholstery carrier and the back upholstery carrier is formed as a structural unit by an integral shell structure.

4. The vehicle seat according to claim 1 , wherein:
the closed frame surrounds the seat member and the backrest at the peripheral side.

5. The vehicle seat according to claim 1 , wherein the carrier frame is constructed in an integral manner.

6. The vehicle seat according to claim 1 , wherein the carrier frame has in the upper end region a shock-absorbing element for receiving impact energy.

7. The vehicle seat according to claim 1 , wherein the seat upholstery carrier is articulated so as to be able to be displaced along the carrier rails for an adjustment of the seat member contemporaneously with adjusting the inclination of the backrest.

8. The vehicle seat according to claim 1 , further comprising a table arranged at a rear side of the vehicle seat on the carrier frame.

9. The vehicle seat according to claim 1 , further comprising an illumination element arranged on the vehicle seat, wherein a cable guide for the illumination element being integrated in the hollow structure of the carrier frame.

10. The vehicle seat according to claim 1 , further comprising a three-point safety belt and a belt redirection device secured to the carrier frame.

11. The vehicle seat according to claim 1 , wherein the carrier frame is constructed as a hollow aluminium rod element; and the seat upholstery and the backrest comprise an upholstery cover.

12. An arrangement comprising two vehicle seats in accordance with claim 1 , the two vehicle seats being arranged so as to be orientated with respect to each other, the carrier frames of the two vehicle seats being connected to each other by a horizontal connection element rigidly connected to the carrier frames or fitted in a recess in a horizontal portion of the carrier frames.

13. The arrangement of vehicle seats according to claim 12 , wherein the horizontal connection element is inserted in an elongated recess in the carrier frame of one of the two vehicle seats so that the one of the two vehicle seats is displaceable relative to the horizontal connection element.

14. The vehicle seat according to claim 1 , further comprising at least one of a ventilation element and a heating element integrated in the hollow structure of the carrier frame, the carrier frame having, at a rear side of the vehicle seat, discharge openings or ventilation nozzles with an adjuster for the one of the ventilation element and the heating element.

15. The vehicle seat according to claim 14 , further comprising discharge openings of the one of the ventilation element and heating element arranged at an inner side of the carrier frame thereby enabling at least one of heating and cooling of the backrest or the seat member.

16. The vehicle seat according to claim 1 , wherein each of the carrier rails have a horizontal first portion arranged at the peripheral side at the lateral edges of the seat member, and an inclined second portion arranged at the peripheral side at the lateral edges of the backrest, the second portion being rigidly connected to the first portion and an opening angle between the first portion and the second portion being in the range from 90° to 135°.

17. The vehicle seat according to claim 1 , wherein the headrest has a concave dishing that defines the lateral sight screens.
