BACKGROUND

1. Field of the Invention

The invention relates to an armrest for a motor vehicle with a vehicle-side support and an armrest element disposed on an upper side of the support and designed to be adjustable relative to the support.

2. Description of the Related Art

Armrests used in motor vehicles generally are integrated into lateral door trims or center consoles and offer no adjustment possibilities at all. The armrests thus always have the same position and height and cannot be adjusted in dependence on the seat position. An individual setting of the armrests that is adapted to the driver or passenger of the motor vehicle thus generally is not possible.

On the other hand, adjustable armrests that are integrated into a door trim of a vehicle door are known in principle from the prior art. For example, DE 10 2006 005 795 A1 describes an adjustable armrest for a motor vehicle that has an elastic support. The elastic support is connected fixedly at one point to a body part or a door of the motor vehicle and, at another is pivotable by a lifting drive. DE 10 2006 026 838 A1 discloses a height-adjustable armrest for a motor vehicle. The adjustment of the armrest is made by an eccentric shaft. EP 1 339 564 B1 discloses an armrest that is in an inner door trim and that is adjustable in the vertical direction of a vehicle.

An object of the present invention is to provide an an adjustable armrest that offers a further increased degree of comfort.

SUMMARY

An armrest for a motor vehicle according to the invention has a further functional element arranged on the upper side of the support at a distance from the armrest element and is designed to be adjustable relative to the support. The further functional element whose position relative to the vehicle-side support can be altered has a positive effect on the comfort and ergonomics of the armrest. It is thus possible to adapt the positions of the armrest element and of the additional functional element independently of one another and in a targeted manner with respect to the ergonomic needs of a user of the motor vehicle. The support may be part of an inner door trim of the motor vehicle. Compromises between design and ergonomics can always arise in the creation of an inner door trim. This conflict of goals can be resolved by the armrest of the invention in that the base positions of the armrest element and of the additional functional element relative to the support are very close to the design requirements. Individual adjustment of the armrest element and the functional element makes it possible for their positions to be adapted appropriately to the ergonomic requirements of a vehicle user. The additional possibility of adjusting the functional element advantageously allows the position of the functional element to be adapted to an armrest adjusted with respect to the base position.

The armrest may have means for adjusting the height of the armrest element relative to the support. This embodiment provides the possibility of adapting the height of the armrest element relative to the support in a user-specific manner. Height adjustability is advantageous since, in terms of its ergonomics, the base height position of the armrest element can always represent only a mean value for different vehicle users. Starting from the base height position, the armrest element can be set higher or lower.

The armrest further may have means for adjusting the inclination of the armrest element relative to the support. The armrest element can be pivoted relative to the support about at least one pivot axis so that the inclination of the armrest element with respect to the support can be varied in a user-specific manner.

To simplify operation, the means for adjusting the height of the armrest element and/or the means for adjusting the inclination of the armrest element may comprise at least one first electrical adjustment device. A single electrical adjustment device may be provided to set the height and the inclination of the armrest element. Alternatively, the adjustment of the height and the inclination of the armrest element relative to the support may be effected by two electrical adjustment devices.

The armrest may have means for adjusting the height of the functional element relative to the support. This provides the possibility of adapting the height of the functional element relative to the support starting from a base height position in a user-specific manner and from the point of view of ergonomics.

The armrest further may have means for adjusting the inclination of the functional element relative to the support. This achieves a situation where the functional element can be pivoted relative to the support about at least one pivot axis so that the inclination of the functional element with respect to the support can be varied in a user-specific manner.

To simplify operation, the means for adjusting the height of the functional element and/or the means for adjusting the inclination of the functional element may comprise at least one second electrical adjustment device. Once again, a single electrical adjustment device can be provided to set the height and the inclination of the armrest element. Alternatively, the adjustment of the height and the inclination of the functional element relative to the support can be carried out by two electrical adjustment devices.

At least one memory may be provided in which the adjustment positions of the armrest element and the functional element are stored so that they can be called up. For example, it is possible, by pressing a memory key, to store the adjustment positions of the armrest element and of the functional element in the memory so that they can be called up. The memory may be designed to store the adjustment positions of the armrest element and of the functional element so that they can be called up for a plurality of vehicle users. The reading of the storage and the setting of the adjustment positions of the armrest element and of the functional element can, for example, take place automatically after the motor vehicle has been opened by a key-based or keyless vehicle access device. Alternatively, the interior of the motor vehicle can be provided with a plurality of selection keys that are linked with the memory so that, by actuating one of the selection keys, the positions of the armrest element and of the functional element are set automatically.

The functional element may be a control panel with a number of control elements, such as control keys and/or control levers, by means of which electrical functional components of the motor vehicle, such as, electric window winders, electrically adjustable outside mirrors or electrical seat adjustment devices, can be actuated. The adaptation of the height and/or of the inclination of the control panel and the adaptation of the height and/or inclination of the armrest element allow particularly effective adaptation to the ergonomic requirements of different vehicle users.

In an alternative embodiment, the functional element can be a further armrest element.

Further features and advantages of the present invention will become clear from the following description of a preferred exemplary embodiment with reference to the appended drawings.

DETAILED DESCRIPTION

An armrest1according to an exemplary embodiment of the invention is arranged on a vehicle door2and comprises a vehicle-side support3. The support3is part of an inner trim4that covers an inner door panel of the vehicle door2relative to the vehicle interior.

The support3is configured in one piece and made of plastic. A gripping recess30is provided in the support3and enables a user to grip the support3of the armrest1to open and close the vehicle door2. The armrest1further comprises an armrest element5that is designed to be adjustable relative to the support3. The armrest element5extends substantially in the longitudinal direction of the motor vehicle when the vehicle door2is closed.

As shown inFIG. 1, the armrest element5is designed so that it is height-adjustable relative to the support3. Thus, the height of the armrest element5relative to the support3can be adapted in a user-specific manner. For this purpose, the armrest1comprises means for adjusting the height of the armrest element5relative to the support3, which means preferably comprise an electrical adjustment device, such as an electrically driven rack and pinion, a worm gear or the like.

As shown inFIGS. 2 and 3, the armrest element5is designed to be pivoted relative to the support3. In this way, the inclination of the armrest element5with respect to the support3can be altered. For this purpose, the armrest1comprises means, such as an electrical adjustment device, with spur gears for adjusting the inclination of the armrest element5relative to the support3. The pivot axis about which the armrest element5can be pivoted extends orthogonally to a longitudinal axis of the armrest element5and thus also substantially perpendicular to the inner trim4of the vehicle door2. The armrest1can have a single (first) electrical adjustment device for adjusting the height and adjusting the inclination of the armrest element5relative to the support3.

As can be seen in the figures, the armrest1has a control panel6in front of the gripping recess30in the longitudinal direction of the vehicle door1. The control panel is arranged on a front portion of the support3that extends obliquely up for reasons of ergonomics. The control panel6has a number of control elements60, in particular a number of control keys and/or control levers, by means of which electrical functional components of the motor vehicle, such as, electric window winders, electrically adjustable outside mirrors or electrical seat adjustment devices, can be actuated.

It becomes clear fromFIG. 4that the control panel6is designed to be height-adjustable relative to the support3so that the height of the control panel6relative to the support3can be adapted in a user-specific manner. For this purpose, the armrest1comprises means for adjusting the height of the control panel6relative to the support3, which means preferably comprises an electrical adjustment device.

As shown inFIGS. 5 and 6, the control panel6is designed to be pivoted relative to the support3. This provides the possibility of altering the inclination of the control panel6relative to the support3. For this purpose, the armrest1comprises means, such as an electrical adjustment device, for adjusting the inclination of the control panel6relative to the support3. The pivot axis about which the control panel6can be pivoted is orthogonal to a longitudinal axis of the control panel6and thus substantially perpendicular to the inner trim4of the vehicle door. The armrest1can have a single (second) electrical adjustment device for adjusting the height and the the inclination of the control panel6relative to the support3.

The armrest element5and the control panel6thus can be adjusted independently of one another in terms of their height and inclination relative to the support3, thus enabling user-specific, ergonomic adaptation of the positions of the armrest element5and of the control panel6.

The adjustment travels of the armrest element5and the control panel6preferably are selected so that in each case maximum adjustment travels are achieved in a mid-two-digit millimeter range (thus approximately between 40 and 60 mm, preferably approximately 50 mm).

There also can have at least one memory within which the adjustment positions of the armrest element5and of the control panel6are stored so that they can be called up. Thus, it is possible that by pressing a memory key, to store the adjustment positions of the armrest element5and of the control panel6in a nonvolatile memory so that they can be called up. It is expedient in this connection if the memory is designed to store the adjustment positions of the armrest element5and the control panel6so that they can be called up for a plurality of vehicle users. The reading of the memory and the setting of the adjustment positions of the armrest element5and of the control panel6can, for example, take place automatically after the vehicle door is opened by a key-based or keyless vehicle access device or by actuating a selection key in the interior of the motor vehicle.
