- Carrier element in a folding package for transport and assembly is Carrier element in a folding package for transport and assembly.
- the material or material is in association with the
- Foam material formed flame retardant and / or fire retardant, so that fires in the vehicle avoided or at least prevents the spread of fires or at least delayed.
- the carrier element has pores and / or openings which are penetrated by the foam material.
- an optimal hold of the cushion formed from the foam material is ensured.
- a distribution of the foam material is optimized.
- the holding element comprises two rod elements, wherein the carrier element between the two
- Rod elements is arranged. This arrangement allows both a secure hold of the headrest on the backrest and on the other hand a high power absorption of the headrest when supporting or catching the head.
- Embodiment favors. Under rising and falling
- Walls of the support element are understood to mean those sections which, due to the bending and / or folding, are designed to descend from a low point or descend to a high point. Such walls are in folded material at a defined angle to each other extending rising and planar areas, generally referred to as convolutions.
- the carrier element has two parallel and by a plurality of rising and falling
- Walls of the support element extending second through openings, through which in each case at least one thread element is guided and fixed in such a way that an extension of the support element along the
- Retaining element is adjustable. This arrangement allows a controlled and defined adjustment of the expansion, ie a controlled and defined widening and narrowing of the support element.
- the expansion of the support element in a particularly advantageous manner after its assembly to the support member individually adjustable, so that always an optimal arrangement and expansion of the support element is achieved.
- a support member for holding a cushion formed of a foam material is attached to the holding member.
- a material is repeatedly bent and / or folded to produce the carrier element.
- the inventive method allows in a simple way the
- a headrest with a bent and / or folded support element which can be easily installed, only requires a small space and forms an optimal support for the foam material during foaming and curing.
- a headrest is produced with a sufficiently good rigidity and strength.
- the material is bent and / or folded several times z-shaped in a development of the method ,
- the support element is two parallel and by a plurality of rising and falling in the Walls of the support element extending second passage openings introduced through which at least one thread element is guided and fixed.
- the respective at least one thread element is guided and fixed.
- Thread element an extension of the support element along the
- Holding element set thus, a controlled and defined adjustment of the expansion of the support element can be performed.
- the carrier element is surrounded for sufficient strength and rigidity with a plastic, in particular foamed or encapsulated.
- the carrier element can be provided with pores and / or small openings. These may, for example, be formed substantially smaller than the passage openings for the implementation of the rod elements, but they may for example also be the same size or larger. On the one hand, these pores and / or openings allow an optimum hold of the pad, which is preferably formed from the foam material, and on the other hand, an optimum foaming process.
- Fig. 1 shows schematically a carrier element for arrangement on a
- Fig. 2 shows schematically a carrier element in a folded
- Fig. 3 shows schematically a holding element with arranged on this
- FIG. 1 shows a carrier element 1 for a headrest for a vehicle seat.
- FIG. 2 shows the carrier element in a folded transport state.
- FIG. 3 shows the carrier element 1 arranged on a holding element 2, which in the mounted state on a backrest of the
- the support element 1 is folded from a soft foldable material.
- the support member 1 is formed of a soft material having a Shore hardness of less than 50 Shore-A. In particular, that is
- the material is preferably flame-retardant and fire-retardant.
- the carrier element 1 is folded in a Z shape and can be pulled in or out like an accordion. As a result of this design of the carrier element 1, in a completely folded state, as shown in FIG. 2, it is designed as a very small and particularly compact transport unit, so that the carrier element 1 has a very small transport volume. In this way support element 1 is very space-saving store and to
- Carrier element 1 to a processing location at which the headrest is to produce
- the holding element 2 comprises two rod elements 2.1, 2.2, which are bent at least at one end.
- the other, opposite straight end of the rod elements 2.1, 2.2 is slidably arranged in the backrest of the vehicle seat.
- the holding member 2 is made of a U-shaped pipe section is formed with a round cross-section, whose
- the carrier element 1 For fastening the carrier element 1 to the holding element 2, the carrier element 1 comprises two parallel and running through all folds
- the carrier element 1 is preferably surrounded with a plastic, in particular foamed or encapsulated. This will form a cushion.
- Through holes 1 .1, 1 .2 are formed. This provides an optimal foaming process and an optimal hold for the used
- Foam material which penetrates the pores 3 and 4 openings given.
- the carrier element 1 additionally and parallel to the passage openings 1 .1, 1 .2 for performing the
- Bar elements 2.1, 2.2 smaller through holes 1 .3, 1 .4, through which one or more thread elements 5 are pulled and fixed such that a controlled and defined expansion and thus mounting the folded support member 1 along the support member 2 and along the rod elements 2.1 , 2.2 is possible.
- the carrier element 1 in the folded state shown in Figure 2 can be particularly easily pushed onto the rod elements 2.1, 2.2, as in this state, the first Through holes 1 .1, 1 .2 are arranged directly behind one another, so that the rod elements 2.1, 2.2 can be threaded into the through holes 1 .1, 1 .2.
- the support element 1 can also be pulled over small radii of the rod elements 2.1, 2.2.
- the carrier element 1 is controlled by means of the thread elements 5 and expand defined and thereby raise along the rod elements 2.1, 2.2.
- this expansion by means of the thread elements 5 is in particular a defined positioning of the support element 1 to the
- Rod elements 2.1, 2.2 in a foaming tool allows to coat it in the foaming process with the foam material.
- the narrow and soft material of the carrier element 1 allows a thin foam layer of the foam material and thereby requires only a small space in the sheathed with the foam material state.
- Such a folded support member 1 allows for easy installation in this way and requires a small space, both in the folded state for transport and in the unfolded and foam material wrapped state in the headrest.
- Contraction of the folded support member 1 allows, so that it can be inserted in the smallest installation spaces during assembly.
- the material of the support member 1 may be bent in a manner not shown or folded in a different manner.
- the bend is formed for example in the form of a sinusoid.
- the convolution can take place, for example, in the form of a rectangular function.
