Definitions
- the invention relates to a structure for a vehicle seat, which comprises rigid structural components forming cavities and a foam structure which at least partially fills the cavities.
- Such vehicle seats are well known.
- a frame made of hollow profiles or a backrest of a vehicle seat is known, wherein in each case a foam is arranged in cavities of structural elements.
- DE 10 2004 043 860 A1 and German published patent application DE 197 46 164 A1 disclose a backrest for a seat or a composite material with an at least partially hollow profile, wherein a foam is arranged in cavities of structural elements.
- Femer is known from German Patent Application DE 42 08 150 A1 and from German Patent Application DE 197 27 907 A1 a backrest for a vehicle seat or a method for filling cavities in workpieces or semi-finished products known.
- the object of the present invention is therefore the targeted training or introduction of a filling in a cavity of a structural element of a vehicle seat to improve the mechanical properties of the vehicle seat, in particular, a very cost-effective assembly method is sought.
- a vehicle seat having a backrest and a seat part, wherein the backrest or the seat part has at least one structure element having a cavity, wherein the cavity is formed by a base plate and at least two profiles connected to the base plate by material engagement, wherein in a corner region two profiles is provided for influencing the stability and / or the deformation behavior of the backrest and / or the seat part introduced filling, wherein the filling comprises a foam carrier and a foam material, wherein the foam material at least partially surrounds the foam carrier and preferably the foam material completely surrounds the foam carrier ,
- the filling comprises a foam carrier and a foam material, wherein the foam material at least partially surrounds the foam carrier and preferably the foam material completely surrounds the foam carrier ,
- the foam material is provided for expansion during the drying process after painting (for example in a drying oven) or that the foam material for expansion during a temperature step (for example in an oven) takes place without painting step.
- a work process which is carried out anyway, carried out a quick and simple assembly technology integration of the foam reinforcement of the vehicle seat.
- the structural element has a corner press piece in the corner region of second profiles. This is it According to the invention, it is possible to obtain a targeted reinforcement on highly stressed areas of the vehicle seat or the backrest and / or of the seat part.
- a method for producing a vehicle seat according to the invention wherein in a first step, the structural element having the cavity is formed, that in a second step in the cavity, the still unexpandator and the foam carrier and the foam material having filling is introduced and that in a third step Temperature step is carried out, in particular in an oven, during which the foam material expands, wherein in particular the temperature step takes place after an electric dip coating, or
- a method for producing a vehicle seat according to the invention wherein in a first step the filling which is still unexpanded and having the foam carrier and the foam material is positioned and / or fastened relative to a part of the structural element, that in a second step the cavity is formed and in that a third step, a temperature step is carried out, in particular in an oven, during which the foam material expands, wherein in particular the temperature step takes place after an electro-dip.
- FIG. 1 schematically shows, as an example of a structural element, a backrest structure or a backrest segment of, for example, a divided folding backrest
- FIGS 2 and 3 show schematic representations of a vehicle seat according to the invention according to all of the embodiments.
- the Lehnensegment 1 and the backrest structure 1 (in the picture is only a Lehnensegment 1, for example split folding backrest shown) comprises a base plate 2 and four patch patch, U-shaped profiles 3.1 to 3.4, which with the base plate 2 and preferably patch Eckpress Suiteen 4 form a rectangular frame with a circumferential hollow chamber 5.
- the base plate 2 and the profiles 3.1 to 3.4 consist essentially of, for example, metal, in particular steel or aluminum sheet, or substantially of plastic, for example of glass fiber reinforced plastic.
- the profiles 3.1 to 3.4 are with the base plate 2 z. B. connected by welding or gluing.
- the connection and / or stiffening of the profiles 3.1 to 3.4 with each other or with the Eckpress brainstormen 4 according to the invention (possibly in addition to welding or gluing) by an angle in the corner areas in the hollow chamber 5 angularly introduced foam structure 6. This stiffens the corner by their inherent rigidity and / or by a local bonding of the profiles 3.1 to 3.4 with each other or with the base plate 2 and / or the Eckpress fabrics 4 from. Alternatively to an embodiment with one or more Eckpress sangen
- corner pressings 4 are completely eliminated and the increased stability requirements in the area of the beak or the higher material tensions to be absorbed by the material are taken up by the profiles 3.1 to 3.4 and the foam structure 6 alone. As a result, it is advantageously possible according to the invention that the weight and the installation space for the corner pressing pieces 4 are saved.
- the introduction of the foam structure 6 can by inserting one of the hollow chamber
- the foam structure 6 is introduced into the hollow chamber 5 only after the welding by injecting a foamable mass.
- particularly preferred is the insertion of a foamable mass
- the backrest structure 1 is stiffened on the one hand in an accidentally heavily loaded area, on the other hand, an additional welding of the profiles 3.1 to 3.4 with each other may optionally be omitted.
- FIGS. 2 and 3 show a vehicle seat according to the invention.
- a vehicle seat comprises a seat part 12 and a backrest 13.
- Both the seat part 12 and the backrest 13 each have at least one structural element 14, which is configured in the context of the present invention in the form of the base plate 2 and the profiles 3.1 to 3.4 or in the form of the base plate 2, the profiles 3.1 to 3.4 and the Eckpress choiren is configured.
- a cavity 15 is provided at least in partial areas, which is also referred to as hollow chamber 5 in the context of the present invention.
- the cavity 15 is formed, for example, like a frame substantially the outer shape or the circumference of the backrest 13 or the seat part 12 following and formed in cross-section substantially angular, rectangular, triangular or angled.
- a filling 16 is arranged in at least a partial region of the cavity 15 and preferably also only in a partial region of the cavity 15, wherein the filling 16 comprises a foam material 18.
- the filling 16 or the foam material 18 is also referred to below as a foam structure.
- the filling 16 or the foam material 18 can be injected by injection of an easily deformable or foaming material from the outside (for example, by an opening located in the cavity 15), it is preferred according to the present invention that the filling 16 in shape a still unexpanded and substantially hard, in any case substantially non-adhesive foam material 18 connected to a foam carrier 17 is introduced into the cavity 15 or fixed or positioned on a structural member forming a cavity wall, the cavity 15 then being formed by bonding to another structural member becomes.
- the foam material 18 is then expanded, whereby the foam material 18, the foam carrier 17 at least partially surrounds or preferably completely surrounds.
- a detail of a cavity 15 formed in the structural element 14 is shown for illustration, the filling 16, ie the foam carrier 17 and the foam material 18, being shown in the hollow space 15 in the unexpanded state of the foam material 18 and in solid lines wherein dashed lines or punctures represent the boundary of the foam material 18 in the foamed state.
- the expansion of the foam material 18 can take place in particular after a cathodic dip bath treatment (not shown). This is understood to mean a treatment in an electrocoating oven or a cathodic dip coating in which the structural elements 14 of the vehicle seat are at a temperature of for example about 160 ° to about 180 °, for example about 5 minutes to about 15 minutes, preferably about 10 minutes , to be brought.
