Abstract

Support structure (1) of a backrest for a vehicle seat, comprising a base plate (1.1) with an edge-parallel channel (1.2) arranged at least in sections, characterized in that clip elements (2) are arranged in sections in the region of the channel (1.2).

Description

The invention relates to a support structure of a backrest for a vehicle seat, comprising a base plate with an edge-parallel channel arranged at least in sections, and a vehicle seat.

State of the art

In the prior art is from the WO 2015/007631 A1 a support structure of a backrest for a vehicle seat known. Here, a base plate is designed so that structural parts are closed as a box section through the base plate and thus contribute to increasing rigidity. A suspension channel is formed from the structural part, wherein an enlarged sheet-metal wall thickness is used.

task

The invention is based on the object to improve a support structure of a backrest for a vehicle seat of the type mentioned above and to provide a corresponding vehicle seat.

solution

This object is achieved by a support structure of a backrest for a vehicle seat, comprising a base plate with an at least partially arranged edge-parallel channel, wherein in the region of the channel sections clip elements are arranged.

The advantages achieved with the support structure according to the invention are, in particular, that a support structure with partially increased rigidity, in particular a rigidity increased in the region of a channel, can be produced in a simple manner.

The danger of the formation of bumps in the base plate, in particular in the vicinity of the channel in subsequent operations is thereby significantly reduced, in particular when mounting profile strips in the channel, which serve to attach a pad to be mounted.

This material saving is possible because in less deformation-prone areas, the support structure on the one hand has a low sheet thickness and on the other hand in the deformation-prone areas, so only partially, due to the clamping elements nevertheless increased and sufficient strength can be achieved.

Advantageous embodiments, which can be used individually or in combination with each other, are described below and / or are the subject of the dependent claims.

The channel may have a substantially C-shaped cross-section. The channel may have two legs arranged substantially parallel, connected by a web. One of the legs is preferably connected to the base plate.

A predetermined number of pairs opposed openings may be disposed in the legs of the channel. Each opening may have a hackenförmigen projection issued in the direction of the web.

The support structure may comprise clip elements. The clip elements may have a substantially C-shaped cross-section. The clip elements may comprise two legs arranged substantially parallel and connected by a web. Each of the legs of the clamping element may have a hook section issued in the direction of the web. Such a support structure is particularly easy to produce and has a partially increased strength in most cases sufficient manner.

The cross section of the clip elements may substantially correspond to the cross section of the channel.

The object is further achieved by a vehicle seat with a backrest, wherein the backrest has a support structure according to the preceding description.

Figures and embodiments of the invention

Before describing embodiments of the invention in more detail with reference to drawings, it should first be noted that the invention is not limited to the described components or the described method steps. Furthermore, the terminology used is not a limitation, but has only exemplary character. Insofar as the singular is used below in the description and the claims, the plural is included in each case, unless the context explicitly excludes this.

1 shows a conventional support structure 1 a backrest for a vehicle; So a support structure 1 According to the state of the art. It is a 40/20/40 split support structure 1 a rear seat attachment.

The three separately hinged elements of this support structure 1 are each made of a metallic base plate 1.1 formed, which is provided to improve the rigidity with a plurality of wells. At the outer edge of each of the elements of this support structure 1 is a channel 1.2 formed, which is also referred to as a suspension channel or trim channel. In such channels 1.2 are mounted on the cushion side various profile strips, not shown here, which serve to attach a pad to be mounted. Such moldings are mounted with some effort, for example, using a rubber hammer. If in the course of mounting a profile strip in a channel unwanted deformation of the base plate, in particular in the area immediately adjacent to the channel, then the unwanted deformation can then be addressed manually, so at least partially resolved.

2 shows a slit image between a cover and a backrest covering according to the prior art.

3 shows a clamp element 2 , The clamp element 2 has a substantially C-shaped cross-section. The clamp element 2 has two legs arranged substantially parallel 2.2 on which by means of a bridge 2.1 are connected. Each of the thighs 2.2 of the clip element 2 points one in the direction of the bridge 2.1 issued hook section 2.3 on.

4 shows a support structure 1 with a peripheral channel 1.2 , The metallic base plate 1.1 preferably has a material thickness of 0.4 mm. The channel 1.2 has a substantially C-shaped cross-section. The channel 1.2 has two substantially parallel arranged by means of a web 1.3 connected thighs 1.4 on, with one of the thighs 1.4 with the base plate 1.1 connected is.

Further, there is a predetermined number of pairs of opposite openings 1.5 in the thighs 1.4 of the canal 1.2 arranged. Every opening 1.5 points one in the direction of the bridge 1.3 exhibited, chop-shaped projection 1.6 on.

The cross section of the clip element 2 corresponds essentially to the cross section of the channel 1.2 , The hook-shaped projections 1.6 serve to attach the profile strip. The hook sections 2.3 serve to fix the clip element 2 on the supporting structure 1 , To fix the on the channel 1.2 plugged clip element 2 grab the hook sections 2.3 in the openings 1.5 one. The clip elements 2 are thus on the channel 1.2 clipped.

The illustrated channel 1.2 with the clamp element 2 has a significantly improved rigidity, so that the risk of the formation of unwanted deformations, especially when using a rubber hammer for mounting a profile strip in the channel 1.2 clearly and easily reduced. Due to the additionally mounted clamp elements 2 is the stability and thus the carrying capacity of the channel 1.2 clearly improved. This results in a particularly positionally accurate and particularly well predeterminable fixation of the profile strips, not shown in the channel 1.2 allows.

The features disclosed in the foregoing description, the claims and the drawings may be of importance both individually and in combination for the realization of the invention in its various forms.

Although the invention has been described in detail in the drawings and the foregoing description, the illustrations are illustrative and exemplary and not limiting. In particular, the choice of the proportions of the individual elements shown in the drawing should not be construed as necessary or restrictive. Furthermore, the invention is not limited in particular to the illustrated embodiments. Other variants of the invention and their execution will become apparent to those skilled in the art from the foregoing disclosure, the drawings and the claims.

Terms used in the claims, such as "comprising,""having,""including,""containing," and the like, do not exclude other elements or steps. The use of the indefinite article does not exclude a majority. A single device can perform the functions of multiple in execute the units or devices mentioned in the claims.
