Description

The invention relates to an armrest for attachment to an aircraft seat in an aircraft according to the preamble of claim 1 and an aircraft seat with such an armrest.

State of the art

Armrests on aircraft seats have already become known in various embodiments.

Due to the high stress, armrests of aircraft seats are often made of steel. For weight reasons, the armrests for aircraft seats may also be made of aluminum.

A disadvantage of aluminum armrests is the comparatively poor strength, which requires large wall thicknesses.

Purpose and advantages of the invention

The invention is based on the object to provide an alternative armrest for attachment to an aircraft seat in an aircraft, which is stable and modular and inexpensive to manufacture.

This object is solved by the features of claim 1 and claims 9-11.

In the dependent claims advantageous and expedient developments of the invention are given.

The invention is based on an armrest for attachment to an aircraft seat in an aircraft, with an armrest element and a support member. The Armauflageelement encloses the support member at least partially.

The essence of the invention lies in the fact that the support member is composed of several support members and that in a section between a front and a rear support member area, at least between two support members, a circumferential, based on the longitudinal axis of the armrest in cross-continuous separation point is formed.

Advantageously, the support member parts at the separation point, before a subsequent connection, completely separated from each other and formed as a single, independent components.

In particular, the separation point is formed in a central region of the support member transversely to the longitudinal axis of the armrest.

Advantageously, a front support member part, for example, a free end and a rear support member part, for example, with a seat divider, advantageously displaceable, in particular pivotally connected. The armrest is rotatably mounted, for example via a pivot bearing on a remaining seat. This allows a user to rotate the support member in an erected, in particular vertical position, relative to the cabin floor. This allows for easier seat occupancy of the user.

The support member is used in particular to receive a force acting on the armrest, and forward it to the aircraft seat.

In an advantageous embodiment, a cable, a communication interface and / or a control element can also be arranged on the support member.

In particular, the support member may include a screen and / or a headphone jack and / or a power connector, for example a USB connector.

Moreover, it is advantageous that a switch for a lighting device and / or for adjusting the volume of a multimedia unit and / or an element of an adjusting mechanism for adjusting, for example, the backrest is attached to the support member.

In an advantageous variant, an enveloping element can be formed, for example, from half-shells. These armrest half shells preferably form the outer wall of the armrest side, bottom and / or front. The armrest half-shells envelop the support member for this purpose advantageously below, laterally and / or front. On top of the armrest, the Armauflageelement can be attached with, for example, a cushion. As a result, the support member is at least partially hidden by the enveloping element and / or the armrest element.

It is further proposed that the armrest can be arranged on an armrest support of the aircraft seat, a seat divider on the aircraft seat and / or directly on a fitting on the aircraft seat.

In an advantageous embodiment, the support member is composed of at least two support member parts, wherein the support member parts abut each other at the separation point.

The support members are designed, for example, approximately the same length. Optionally, three or more support members are provided.

The front and the rear support member part, for example, in the direction of the longitudinal axis of the armrest about the same length. In particular, the support member parts butt against each other, but the support members can also overlap advantageous.

It is also advantageous that the support member is hollow.

The support member may be formed as a hollow housing. The support member has, for example, in its cross section over a relatively large area, transverse to the longitudinal axis of the armrest, a C-shaped shell structure. The open end of the C-shaped lateral surface is arranged for example on the armrest at the bottom or at the top and optionally serves for the arrangement of the armrest element.

Advantageously, it also proves that the support member parts are connected to each other at the separation point via a latching connection.

In particular, on a support member part at the separation point a groove and the adjoining support member part at the separation point a matching counterpart may be formed so that the support member parts can latch and / or jam.

It is also advantageous that the support member parts are firmly connected to each other at the separation point.

The support members may be glued and / or welded and / or soldered at the point of separation.

In particular, the separation point can have a depression, for example a groove, in order to be able to receive and clearly position solder, a welding medium, adhesive and / or another bonding material for connecting the support element parts.

The support member parts are, for example, overlappingly connected to each other at a separation point via connecting surfaces.

A connecting surface of the support member parts may extend in the direction of the longitudinal axis of the armrest less than 10 mm, advantageously less than 5 mm, in particular less than 1, 2, 3, 4, 5 mm.

In an advantageous variant, the support member parts are formed from the same material.

As a result, the two support member parts have the same chemical and / or mechanical properties, in particular with regard to their rigidity, their expansion coefficient, their mechanical processing capability and / or their ability to connect.

It also proves advantageous that the support member parts are cast.

The support member part can be manufactured by means of a die-casting process. The cast blank of the support member part is in particular mechanically reworked, for example milled, drilled, lasered, ground, deburred and / or sandblasted.

Advantageously, the support member parts are formed of titanium.

Titanium has a high strength and is relatively easy to machine, for example, machinable. In addition, titanium, especially at very thin wall thicknesses high strength and dimensional stability.

In addition, titanium is relatively easy to weld with conventional welding.

In an advantageous embodiment of the armrest according to the invention, the weight of the armrest is composed of a support member, an enveloping element and an armrest element, for example in a weight range between 200 and 600 g (grams), between 300 and 500 g, between 350 and 500 g, between 350 and 450 g, advantageously between 400 and 440 g, in particular between 420 and 440 g.

In particular, it is possible according to the invention to provide the support member of an armrest in lightweight construction or with a weight of about 200 grams. The armrest with attachments (support member, wrapping element, Armauflageelement) can then advantageously have a low weight of about 430 grams.

In a further advantageous variant, the wall thickness of the support member over a large shell region is less than 1 mm.

The wall thickness of the support member may have a wall thickness of less than 1 mm over a jacket region of at least 70% of the wall surface of the support member, advantageously over a jacket region of the support member of at least 90% of the wall surface. Over a mantle area between 0 and 30% of the lateral surface, the support member may for example have a wall thickness between 0.6 to 0.8 mm, in particular over a mantle region of the support member between 5% to 25%.

The enveloping element may be formed, for example, of plastic.

In addition, the enveloping element can be composed of several parts modular. For example, it is composed of a front, a rear and a right and / or a left part. The parts surround the support member and are, for example, clamped together and / or glued and / or welded.

In a further advantageous embodiment, the enveloping element and / or the Armauflageelement is firmly connected to the support member.

The enveloping element and / or the Armauflageelement may be connected to the support member clamping and / or adhesive.

In a further advantageous modification, the support member is formed in one of the aforementioned variants as a kit.

The kit is characterized in that a front support member part and a plurality of different matching rear support member parts are provided or that a rear support member part and a plurality of different matching front support member parts are provided or provided that several different front support member parts and a plurality of different matching rear support member parts are.

Due to the advantageous embodiment of the support member as a kit can be a cheap and / or flexible mass production of different supporting organs and thus armrests are made possible.

For example, if a detail of the armrest to change due to a customer request or due to a technical requirement, so only the corresponding component and / or the mold of the corresponding component to change. As a result, it is comparatively easy to provide a suitable component in the kit.

Due to the configuration of titanium, the component to be modified can be relatively easily reworked mechanically. In the case of the necessity of changing the mold, it is not necessary to change the entire mold of the support member, but only a comparatively smaller mold of the support member. As a result, a cost-effective production is possible.
