Abstract

An arm rest arrangement for a motor vehicle seat with a fixed carrier structure and an arm rest body mounted for pivoting about an axis in relation thereto, and with which an incline adjustment device is associated, allowing a modification of an incline of the arm rest body in relation to the carrier structure. The incline adjustment device includes an actuating member and a blocking device for securing an incline adjustment carried out by the actuating member. The arm rest body include a supporting member adjustable in a linearly movable manner on the arm rest body and supported on the carrier structure. The actuating member and the blocking device are connected to the supporting member such that same can be released by the actuating member for a linear adjustment and can be stopped by the blocking device in an adjusted supporting position.

First claim

The invention claimed is:

1. An armrest arrangement for a motor vehicle seat, said armrest arrangement comprising a carrier structure, an armrest body mounted so as to be pivotable relative to the carrier structure about a pivot axle, and an inclination adjustment device which, in a functional supporting position of the armrest body, permits a variation of an inclination of the armrest body relative to the carrier structure, the inclination adjustment device having a manually operable actuating element and blocking device for securing an inclination setting performed by the actuating element, the armrest body having a support element which is adjustable in a linearly movable fashion in a linear movement direction transverse to the pivot axle, the support element having an end supported on a support surface of the carrier structure in the functional supporting position of the armrest body, the carrier structure and the support surface thereof being positionally fixed and non-movable relative to the support element, the end of the support element being disposed to engage the support surface of the carrier structure along the linear movement direction of the support element in the functional supporting position of the armrest body, the actuating element and the blocking device being operatively connected to the support element such that the support element can, by the actuating element, be released for a linear adjustment and, by the blocking device, be locked in a set support position.

2. The armrest arrangement as claimed in claim 1 , wherein the inclination adjustment device includes a guide non-movably fixed to the armrest body and the support element is held in a positively locking fashion in an adjustment direction by the guide.

3. The armrest arrangement as claimed in claim 2 , wherein the support element is mounted for rotation relative to the armrest body and the guide, the support element and the guide being threadedly engaged with one another.

4. The armrest arrangement as claimed in claim 3 , further including a drive configured to load the support element, the drive comprising a torsion spring which is arranged coaxially with respect to a movement thread defined in the guide, the torsion spring being supported at one side on the support element and at the other side on the guide.

5. The armrest arrangement as claimed in claim 1 , further including a drive configured to load the support element in at least one adjustment direction.

6. The armrest arrangement as claimed in claim 5 , wherein the drive comprises a mechanical spring drive.

7. The armrest arrangement as claimed in claim 1 , wherein the blocking device comprises a wrap brake oriented coaxially with respect to the support element.

8. The armrest arrangement as claimed in claim 1 , wherein the movement direction of the support element intersects the support surface of the carrier structure in the functional supporting position of the armrest body.

9. The armrest arrangement as claimed in claim 1 , wherein the end of the support element is disposed in direct abutting engagement with the support surface of the carrier structure in the functional supporting position of the armrest body and exerts a force on the support surface primarily along the linear movement direction of the support element.

10. A motor vehicle seat having at least one armrest arrangement as claimed in claim 1 .

11. An armrest arrangement for a motor vehicle seat comprising:
a carrier structure defining an axis and including thereon a support area;
an armrest body defining thereon a surface configured for supporting an arm of a user, said armrest body being mounted for pivotable movement relative to said carrier structure about the axis thereof between at least one raised non-use position wherein said surface of said armrest body is oriented at a first angle relative to the horizontal and at least one lowered use position wherein said surface of said armrest body is oriented at a second angle relative to the horizontal, said second angle being less than said first angle; and
an inclination adjustment arrangement configured to permit variation of a position of said armrest body relative to said carrier structure, said inclination adjustment arrangement comprising:
a support element mounted on said armrest body for linear movement along a direction transverse to the axis of said carrier structure, said support element having a first end disposed adjacent said carrier structure and a second end spaced from said first end;
a blocking device operatively connected to said support element; and
a manually operable actuating element disposed on said armrest body and operatively connected to said blocking device, said actuating element having a first position in which said blocking device is disposed to prevent linear movement of said support element and lock same in a fixed position relative to said armrest body, and a second position in which said support element is linearly movable relative to said armrest body to permit selective adjustment of a position of said armrest body relative to said carrier structure, said carrier structure and said support area thereof being fixed in position and non-movable relative to said support element, said first end of said support element being disposed to engage said support area of said carrier structure and exert a force thereon primarily along the direction of linear movement in the lowered use position of said armrest body.

12. The armrest arrangement as claimed in claim 11 , wherein the direction of linear movement of said support element intersects said support area of said carrier structure in the lowered use position of said armrest body.

13. The armrest arrangement as claimed in claim 12 , wherein said first end of said support element is disposed in direct contact with said support area of said carrier structure in the lowered use position of said armrest body.

14. The armrest arrangement as claimed in claim 11 , wherein said inclination adjustment arrangement further comprises a guide element non-movably fixed to said armrest body and disposed to supportively engage said support element during linear displacement thereof, said first end of said support element having a section extending between said guide element and said support area of said carrier structure in the lowered use position of said armrest body, wherein a length of said section extending between said guide element and said support area is variable through linear displacement of said support element relative to said guide element to permit selective adjustment of a position of said armrest body relative to said carrier structure.

15. The armrest arrangement as claimed in claim 11 , wherein said support element is mounted on said armrest body for rotational movement relative to said carrier structure about a rotational axis coextensive with the direction of linear movement of said support element.

16. The armrest arrangement as claimed in claim 11 , wherein said support element is mounted on said armrest body for both linear movement along the direction transverse to the axis of said carrier structure and rotational movement about an axis transverse to the axis of said carrier structure.

17. The armrest arrangement as claimed in claim 11 , wherein said support element is mounted on said armrest body for rotational movement about an axis transverse to the axis of said carrier structure, and said inclination adjustment arrangement further comprises a guide element non-movably fixed to said armrest body, said support element and said guide element threadingl
