Abstract

A seating device with reduced bulk, for example for an aircraft. This seating device comprises a backrest which describes a circular translational movement towards the front and upwards of the device when the seating device is brought to the retracted configuration. A seating structure is provided comprising a bearing piece on which are fixed, side by side, a plurality of seating devices with reduced bulk. An aircraft is provided comprising a seating device with reduced bulk mounted in its cabin.

First claim

The invention claimed is:

1. A seating device with reduced bulk comprising:
a support supporting a seating and a backrest,
the seating device having a plurality of configurations of use offering a seating place and being movable to a retracted configuration offering a reduced bulk,
the backrest being configured to move towards a front of the seating device when the seating device is moved to the retracted configuration,
the backrest describing a circular translational movement towards the front and upwards relative to the device when the seating device is moved to the retracted configuration,
the seating and the backrest of the seating device being mounted on a deformable parallelogram-shaped support structure having a front stay, a rear stay, a top stay and a bottom stay, each stay being pivotally joined to two adjacent stays, the front stay formed by a portion of the support, the rear stay formed by a portion of the backrest,
wherein the seating rotationally tilts about a horizontal axis positioned on the support so that its front end is moved downwards and towards the rear of the device, and its rear end is moved upwards and towards the front of the device when the seating device is moved to the retracted configuration.

2. The seating device with reduced bulk according to claim 1 , wherein the seating is fixed to the top stay of the deformable parallelogram-shaped support structure.

3. The seating device with reduced bulk according to claim 1 , wherein the seating comprises a saddle with a front part thinner than a rear part, the front part being raised relative to the rear part in a seating configuration.

4. The seating device with reduced bulk according to claim 1 , wherein the backrest comprises a lumbar support held at the end of an arm.

5. The seating device with reduced bulk according to claim 1 , wherein the seating has a rotational mobility about a vertical axis relative to the support.

6. The seating device with reduced bulk according to claim 1 , wherein the support incorporates means for adjusting the seating height.

7. The seating device with reduced bulk according to claim 1 , wherein the seating device comprises an armrest with an arm rotationally mounted about an axis that is fixed relative to the support, the armrest comprising a support element for a forearm of a passenger mounted on a slideway at a top end of the arm.

8. A seating structure comprising a bearing piece on which are fixed, side by side, a plurality of seating devices so as to form a row of seating places, the seating devices each comprising:
a support supporting a seating and a backrest,
the seating device having a plurality of configurations of use offering a seating place and being movable to a retracted configuration offering a reduced bulk,
the backrest being configured to move towards a front of the seating device when the seating device is moved to the retracted configuration,
the backrest describing a circular translational movement towards the front and upwards relative to the device when the seating device is moved to the retracted configuration,
the seating and the backrest of the seating device being mounted on a deformable parallelogram-shaped support structure having a front stay, a rear stay, a top stay and a bottom stay, each stay being pivotally joined to two adjacent stays, the front stay formed by a portion of the support, the rear stay formed by a portion of the backrest,
wherein the seating rotationally tilts about a horizontal axis positioned on the support so that its front end is moved downwards and towards the rear of the device, and its rear end is moved upwards and towards the front of the device when the seating device is moved to the retracted configuration.

9. An aircraft comprising at least one seating device mounted in its cabin, the seating device comprising:
a support supporting a seating and a backrest,
the seating device having a plurality of configurations of use offering a seating place and being movable to a retracted configuration offering a reduced bulk,
the backrest being configured to move towards a front of the seating device when the seating device is moved to the retracted configuration,
the backrest describing a circular translational movement towards the front and upwards relative to the device when the seating device is moved to the retracted configuration,
the seating and the backrest of the seating device being mounted on a deformable parallelogram-shaped support structure having a front stay, a rear stay, a top stay and a bottom stay, each stay being pivotally joined to two adjacent stays, the front stay formed by a portion of the support, the rear stay formed by a portion of the backrest,
wherein the seating rotationally tilts about a horizontal axis positioned on the support so that its front end is moved downwards and towards the rear of the device, and its rear end is moved upwards and towards the front of the device when the seating device is moved to the retracted configuration.

10. The seating structure according to claim 8 , wherein the seating has a rotational mobility about a vertical axis relative to the support.

11. The seating structure according to claim 8 , wherein the support incorporates means for adjusting the seating height.

12. The seating structure according to claim 8 , wherein the seating device comprises an armrest with an arm rotationally mounted about an axis that is fixed relative to the support, the armrest comprising a support element for a forearm of a passenger mounted on a slideway at a top end of the arm.

13. The aircraft according to claim 9 , wherein the seating has a rotational mobility about a vertical axis relative to the support.

14. The aircraft according to claim 9 , wherein the support incorporates means for adjusting the seating height.

15. The aircraft according to claim 9 , wherein the seating device comprises an armrest with an arm rotationally mounted about an axis that is fixed relative to the support, the armrest comprising a support element for a forearm of a passenger mounted on a slideway at a top end of the arm.

16. A seating device with reduced bulk comprising:
a support supporting a seating and a backrest,
the seating device having a plurality of configurations of use offering a seating place and being movable to a retracted configuration offering a reduced bulk,
the backrest being configured to move towards a front of the seating device when the seating device is moved to the retracted configuration,
the backrest describing a circular translational movement towards the front and upwards relative to the device when the seating device is moved to the retracted configuration,
the seating and the backrest of the seating device being mounted on a deformable parallelogram-shaped support structure having a front stay, a rear stay, a top stay and a bottom stay, each stay being pivotally joined to two adjacent stays, the front stay formed by a portion of the support, the rear stay formed by a portion of the backrest,
wherein the support is in the form of a vertically oriented member, the seating having a front end positioned forward of a vertical extension of the support and a rear end positioned rearward of the vertical extension of the support when the seating is in a non-retracted configuration, and being configured to rotationally tilt about a horizontal axis located on a portion of the support so that the front end is moved downwards and closer horizontally to the support and a rear of the device, and the rear end is moved upwards and towards the front of the device so as to move at least a por
