Description

The invention relates to an armrest for a vehicle, comprising a vehicle-fixed armrest body, a first armrest and a second armrest, which are pivotable about a common axis of rotation, wherein the first armrest has a first radial bearing for the axis of rotation and the second armrest a second radial bearing for the Has rotational axis. The invention also relates to a method for assembling the armrest.

The invention is particularly applicable to center consoles of motor vehicles.

The DE 10 2005 029 635 B4 discloses an armrest for a vehicle having an armrest body and a cover pivoted thereto about a pivot axis, the cover being rotatably connected to a separate hinge member to form a prefabricated assembly, the hinge member being fixedly connected to the armrest body and the hinge member being a plurality of parallel spaced, in the installed position substantially vertical ribs, between which extend corresponding ribs of the cover.

The DE 10 2007 027 608 A1 discloses a height-adjustable armrest for motor vehicles, which is provided with a guide and a drive means. The guide device ensures that the Armauflagepolster can be adjusted substantially without inclination change up and down. The adjustment is carried out by electric motor with the help of a self-locking screw spindle drive.

It is the object of the present invention to overcome the disadvantages of the prior art, at least in part, and in particular to provide an armrest for vehicles, which is particularly easy to assemble and / or easy to maintain outside the factory.

This object is achieved according to the features of the independent claims. Preferred embodiments are in particular the dependent claims.

The object is achieved by an armrest for a vehicle, comprising a vehicle-fixed armrest body, a first armrest and a second armrest, which are pivotable about a common, attached to the armrest body axis of rotation, the first armrest having a first radial bearing for the axis of rotation second armrest having a second radial bearing for the axis of rotation, the axis of rotation has a first axial part and a second axial part which are axially loosely inserted between the radial bearings, the first axis part is pushed through the first radial bearing, the second axis part is pushed through the second radial bearing in that the first axle part, with its portion pushed through by the first radial bearing, is fastened to a support connected to the armrest body, and the second axle part with its portion pushed through by the second radial bearing is fastened to the support.

This armrest has the advantage that it is particularly easy, quick and inexpensive to assemble and disassemble. It can also be easily maintained outside the factory, without having to disassemble major components of the vehicle-fixed armrest body. There are no fiber composite components needed for the pivoting mechanism.

The first armrest and the second armrest may also be considered parts of a split armrest. In particular, an armrest may be provided for a vehicle occupant seated on the left and the other armrest may be provided for a vehicle occupant seated on the right side.

The radial bearing may be a radial plain bearing, in particular a tubular or sleeve-shaped plain bearing.

The axis parts can be intercept sections. That the axially between the radial bearings are loosely inserted into each other, may in particular include that the two axle parts are axially against each other. It is a development that the axis of rotation can be pushed together or put together to a length which is smaller than a distance of their attachment points to the carrier. This provides the advantage that the axis of rotation on the support is particularly easy to fasten, in particular by hand.

The axle parts protrude on the outside via the respective radial bearings. This allows a particularly simple attachment to the carrier. Generally, an arrangement "between the two radial bearings" can be understood below by an "inside" arrangement, an arrangement on the other side (facing the carrier) of the radial bearings under an "outside" arrangement.

The object is also achieved by a method for assembling the armrest, wherein in a step (a) the first axle part is inserted inside or inside of the first radial bearing and the second axle part is inserted from the inside into the second radial bearing; in a step (b) the first armrest and the second armrest are arranged side by side under mating of the axle parts; in a step (c), the first armrest and the second armrest are pressed against each other; in a step (d) the first armrest and the second armrest are inserted in the carrier in the compressed state; in a step (e), the first axle part and the second axle part are moved apart laterally, so that the sections of the axle parts inserted through the radial bearings engage in the carrier and then, in a step (f), the pushed-through sections are fastened to the carrier.

This method makes it possible to assemble, maintain and disassemble the armrest in a particularly simple and inexpensive manner.

By squeezing the two armrests in step (c), the two axis parts are inserted into each other so strongly that they can be inserted into the carrier in step (d). Step (c) may also include only lightly contacting the armrests. In principle, a compression can also be completely dispensed with, as long as only the axle parts are inserted into each other.

It is an embodiment that the axle parts rest on compression springs on the respective radial bearings, in particular on the inside end faces of the radial bearings. As a result, an equal contact pressure of the axle parts to the radial bearings can be achieved for both sides. The contact pressure also makes it possible to exert a precise braking action or motion damping on a rotational movement of the armrests.

The compression springs can be placed in an embodiment before step (a) on associated attachment areas of the axle parts or be. The attachment areas serve in particular as a stop against a free movement of the compression springs in the direction of the other radial bearing. With step (a), the respective axle parts are inserted into the associated radial bearings so that the compression springs are arranged between the attachment areas and the radial bearings.

The compression springs may be coil springs, rubber rings, etc. The coil springs may be conical springs, coil springs, etc.

It is still an embodiment that the pushed through portions of the axle parts are secured against rotation on the carrier, in particular inserted or inserted into the carrier. This allows a particularly simple and uniform pivoting movement of the armrests. It is a development of the fact that the axle parts have a non-circular cross-sectional contour at their outer ends which are pushed through by the radial bearings and the carrier has a matching recess. The cross-sectional contour may, for example, have two opposite straight sides.

It is an embodiment that in step (e) the sections pushed through by the radial bearings are not only secured against rotation to the carrier but are also inserted axially displaceably into the carrier. The axial displaceability also makes it possible in a particularly simple manner to precisely set an axial position of the axle parts in relation to the carrier and thus also a contact pressure of the compression spring.

It is still an embodiment that the axle parts have screw threads at their inserted sections and are fastened to the carrier by means of respective screw elements. This allows a fast, inexpensive, reliable and easily adjustable attachment. The axle parts can therefore be bolted to the carrier.

It is a development that the screw is a nut. The inserted portion of the associated axle part is then in particular an external screw thread. This makes it possible to keep the inserted section particularly thin.

It is still a development that the axle parts have frontally introduced screw holes. The associated screw is then a screw. This enables a particularly compact design and reliable fastening.

It is an embodiment of that an axial position of the axle parts to the carrier by means of the screw elements is adjustable. This can be adjusted particularly precisely and simply by selecting the revolutions of the screw element.

It is still an embodiment that a spacer between the axle parts is used. The spacer limits an axial movement of the two axis parts towards each other. This is particularly advantageous to prevent slippage from previously - e.g. in step (e) - to prevent ends of the axle sections inserted into the carrier. The spacer is so large that it sets the axis of rotation to a minimum length which is equal to or greater than a distance between associated attachment points of the carrier.

It is still an embodiment that the spacer is rotatable about or against the axis of rotation. This allows a particularly reliable attachment of the spacer, for example on a vehicle-fixed component, eg a firm connection with the armrest body. The spacer is attachable to the carrier.

The armrest can be integrated into a center console or form part of a center console. The armrests can cover storage compartments and then serve as covers or covers.

It is a development that the armrests are each linearly displaceable against the axis of rotation, in a direction perpendicular to the longitudinal extent of the axis of rotation. This can be implemented, for example, by the fact that the radial bearings represent regions (in particular end regions) of a respective push rod and armrest cushions of the armrests are translationally displaceable relative to the respective push rod.

The object is also achieved by a vehicle having the above armrest.

The vehicle can be a motor vehicle ( z .B. a motor vehicle such as a passenger car, lorry, bus, etc. or a motorcycle), a train, a watercraft ( z .B. a boat or a ship) or an aircraft ( z .B. an airplane or a helicopter).
