Description
VEHICLE SEAT FOR AN AUTOMOBILE
DESCRI P110 N The preáent invention relates to a vehicle seat according to the preamble of claim 1, a method for manufacturing a vehicle seat according to the preamble of claim 9 and an automobile according to the preamble of claim 14.
Automobiles are used to accommodate people and have vehicle seats for accom-modating the same inside an interior. The vehicle seats consist of a seat portion and a back portion. A seat cushion is disposed on the seat portion and a back cushion is fastened to the back portion. A seat covering for the seat portion and the back por-tion is fixed on each of the seat cushion and the back cushion so that a seat surface is provided on the seat portion and a back surface is provided on the back portion.
Vehicle seats having a seat depth adjuster comprise a seat portion having a base portion and an adjusting portion. The adjusting portion is mounted movably relative to the base portion in the longitudinal direction of the vehicle seat or the automobile.
The extension or the size of the seat surface in the direction of the longitudinal di-rection can thereby be varied and adapted to persons or passengers in a different size. For movement of the movable adjusting portion relative to the immovable or stationary base portion with regard to a change in the extension of the seat surface in the longitudinal direction, an adjusting force can be applied to the adjusting por-tion by means of a means, e.g. a helical spring and/or a movement member, e.g. a handle, for movement of the adjusting portion relative to the base portion. For the manufacture of vehicle seats having different means for application of the adjusting force to the adjusting portion, different base portions and/or adjusting portions are therefore required in a disadvantageous manner in order to be able to provide dif-ferent means on the vehicle seat. This is associated in a disadvantageous manner with higher costs and a major logistical expenditures for the components to be used.
Known from WO 2012/055698 Al is a vehicle seat having a seat pan for carrying a seat cushion of the vehicle seat. A support element is adjustable relative to a seat pan along an adjusting direction for carrying an additional cushion which is adjusta-ble relative to the seat cushion of the seat pan. The support element can be moved relative to the seat pan by means of a seat depth adjusting device which is disposed on the seat pan. The seat depth adjusting device comprises a guide assembly carry- ing the support element and an actuating assembly for actuating the seat depth ad-justing device. The guide assembly on the seat pan is guided movably along the adjusting direction by means of guide means.
It is therefore the object of the present invention to provide a vehicle seat, a method for manufacturing a vehicle seat and an automobile in which different means for applying an adjusting force to the adjusting portion can be disposed on the vehicle seat and the vehicle seat is cheap to manufacture.
This object is solved by a vehicle seat comprising a seat depth adjuster, in particu-lar for an automobile, comprising a seat portion comprising a base portion and an adjusting portion, wherein the adjusting portion is movable relative to the base por- tion in the longitudinal direction, a mounting for the movable mounting of the adjust-ing portion relative to the base portion, a means for applying an adjusting force to the adjusting portion for moving the adjusting portion, a back portion, a seat cover for the seat portion and a seat cover for the back portion, wherein the vehicle seat comprises a receiving element for a reel of a constant force spring as the means and a receiving element fastening geometry for fastening the receiving element or the vehicle seat comprises a first helical spring fixing element for fixing a helical spring as the means to the base portion and a first helical spring fixing element fas-tening geometry for fastening the first helical spring fixing element and comprises a second helical spring fixing element for fixing the helical spring as the means on the adjusting portion and a second helical spring fixing element fastening geometry for fastening the second helical spring fixing element or the vehicle seat comprises a first pneumatic fixing element for fixing a pneumatic element as the means on the base portion and a first pneumatic fixing element fastening geometry for fastening the first pneumatic fixing element and a second pneumatic fixing element for fixing the second pneumatic element as the means on the adjusting portion and a sec- ond pneumatic fixing element fastening geometry for fastening the second pneu-matic fixing element or the vehicle seat comprises a fastening device for fastening an electric motor as the means and an electric motor fastening geometry for fas-tening the fastening device. In one embodiment of the receiving element in one piece with the base portion or the adjusting portion, the vehicle seat has no receiv-ing element fastening geometry for fastening the receiving element.
In one embodiment of the receiving element as a separate component in addition to the base portion or the adjusting portion, a receiving element fastening geometry is formed on the vehicle seat, in particular on the base portion or the adjusting portion and a complementary counter-fastening geometry is provided on the receiving ele-ment so that by means of the complementary counterlastening geometry on the receiving element, this is fastened positively and/or non-positively on the receiving element fastening geometry. This also applies in similar manner for the first screw fixing element, the second screw fixing element, the first pneumatic fixing element, the second pneumatic fixing element and the fastening device for the electric motor in each case as separate components.
In contrast to this, in the first screw fixing element with a one-part configuration of the first screw fixing element on the base portion, no first screw fixing element fas- tening geometry and also no counter-fastening geometry are provided on the vehi-cle seat. This applies similarly for the other fixing elements described in this property rights application which are not formed as separate components in addition to the base portion or adjusting portion but in one piece with the base portion or adjusting portion.
In one embodiment of the first screw fixing element as a separate component in addition to the base portion, a complementary counter-fastening geometry is formed on the first screw fixing element, e.g. a latching projection, a latching recess, a latch-ing slot, and by means of this the first screw fixing element on the first screw fixing element fastening geometry, e.g. a latching projection, a latching recess, a latching connecting piece, of the base portion is fastened positively and/or non-positively in the base portion. The first helical screw fixing element fastening geometry is formed geometrically complementary to the counter-fastening geometry. This applies simi-larly for the other fastening geometries described in this property rights application.
Consequently in an advantageous manner different means for applying the adjust-ing force to the adjusting portion can be disposed and fastened on the vehicle seat with an identical base portion and/or adjusting portion. The costs for manufacturing the vehicle seat can thereby be reduced and as a result of a thereby possible modu-lar design, different means can thus be fastened on the identical base portion and the identical adjusting portion during the manufacture of the vehicle seat.
In particular, the receiving element is connected to the base portion or to the adjust-ing portion, in particular the receiving element is configured in one piece on the base portion or on the adjusting portion. The receiving element fastening geometry is therefore formed either on the base portion or the adjusting portion and the com-plementary counter-fastening geometry is formed on the receiving element. As a result, the receiving element in a two-part configuration in addition to the base por- tion or the adjusting portion can be fastened or is fastened either on the base por-tion or the adjusting portion.
In a further embodiment the receiving element is configured as a drum or a recess.
In an additional embodiment the vehicle seat comprises a fixing element for one end of the band outside the reel of the constant force spring. By means of the fixing ele-ment, the end of the band of the constant force spring can be fastened anwor is fastened or can be fixed as one end outside the reel on the vehicle seat, in particu-lar on the base portion or the adjusting portion.
Preferably the vehicle seat comprises as the means for application of an adjusting force to the adjusting portion a constant force spring or a helical spring or a pneu-matic element, eg. a pneumatic bladder or a pneumatic piston or an electric motor and/or a movement member, preferably a handle or a lever, for manual application of an adjusting force to the adjusting portion.
In one variant the vehicle seat comprises a locking device having an actuating member, preferably a handle or a lever, so that in a locking position of the locking device the movability of the adjusting portion relative to the base portion is locked or impeded and in an unlocking position the adjusting portion is movable relative to the base portion. The locking device comprises, for example, a rod configured with teeth in which in the locking positon a detent engages positively in the teeth and in an unlocking position the detent is located outside the teeth or of intermediate spac-es between the teeth.
Expediently the vehicle seat comprises an elastic seat cushion, preferably made of foam, in particular comprising a first seat cushion on the base portion and a sec-ond seat cushion on the adjusting portion, andlor the vehicle seat comprises an elastic back cushion, preferably made of foam and/or the vehicle seat is manufac-tured by a method described in this property rights application and/or the adjusting portion and/or the base portion is or are configured in a plate shape each having an upper contact surface for indirect delimitation of a seat surface. The adjusting por-tion and/or the base portion are configured to be substantially plate-shaped since respectively one first and second seat cushion is fastened on the adjusting portion and the base portion and the seat cushion indirectly with the seat cover forms the seat surface.
In a further embodiment, the receiving element fastening geometry is configured for fastening the receiving element on the base portion or on the seat portion and/or the first helical spring fixing element fastening geometry is configured for fastening the first helical spring fixing element on the base portion and/or the second helical spring fixing element fastening geometry is formed on the adjusting portion and/or the first pneumatic fixing element fastening geometry for fastening the first pneumat-ic fixing element is formed on the base portion and/or the second pneumatic fixing element fastening geometry for fastening the second pneumatic fixing element is formed on the adjusting portion and/or the electric motor fastening geometry for fas-tening the fastening device is formed on the base portion or the adjusting portion.
The method according to the invention for manufacturing various vehicle seats comprising a seat depth adjuster, in particular various vehicle seats described in this property rights application comprises the steps: providing a seat portion with a base portion and an adjusting portion, wherein the adjusting portion is movable relative to the base portion in the longitudinal direction, providing a mounting for movable mounting of the adjusting portion relative to the base portion, providing a means for application of an adjusting force to the adjusting portion for movement of the adjust-ing portion, providing a back portion, providing a seat cover for the seat portion and providing a seat cover for the back portion, mounting the seat portion with the base portion, with the adjusting portion, with the mounting, with the means as well as the back portion and the seat cover for the seat portion and the seat cover for the back portion to the vehicle seat, wherein at least one different means for different vehicle seats is mounted on an identical base portion and/or an identical adjusting portion.
In an advantageous manner, different means for application of an adjusting force to the adjusting portion can thus be disposed and mounted on the vehicle seat with an identical base portion and/or an identical adjusting portion. In modular design differ-ent means can thus be mounted on the vehicle seat with the identical base portion and the identical adjusting portion so that vehicle seats with different means can thus be manufactured with low manufacturing costs.
In particular, a constant force spring or a helical spring or a pneumatic element, e.g. a pneumatic bladder or a pneumatic piston or an electric motor and/or a movement member, preferably a handle or a lever for manual application of an adjusting force to the adjusting portion are mounted as various means for application of an adjust-ing force to the adjusting portion.
In a further embodiment the adjusting portion or the base portion are provided with a receiving element for a reel of a constant force spring and/or with a receiving ele-ment fastening geometry for fastening the receiving element and/or a first helical spring fixing element for fixing a helical spring is provided as the means on the base portion and/or the base portion is provided with a first helical spring fixing element fastening geometry for fastening the first helical spring fixing element and a second helical spring fixing element for fixing the helical spring is provided as the means on the adjusting portion and/or the adjusting portion is provided with a sec-ond helical spring fixing element fastening geometry for fastening the second helical spring fixing element and/or a first pneumatic fixing element for fixing the pneumatic element is provided as the means on the base portion and/or the base portion is provided with a first pneumatic fixing element fastening geometry for fastening the first pneumatic fixing element on the base portion and a second pneumatic fixing element for fixing the second pneumatic element is provided as the means on the adjusting portion and/or the adjusting portion is provided with a second pneumatic fixing element fastening geometry for fastening the second pneumatic fixing element and/or a fastening device for fastening an electric motor is provided as the means and/or the base portion or the adjusting portion is provided with an electric motor fastening geometry In an additional variant a locking device is provided with an actuating member, pref-erably a handle or lever and mounted so that in a locking position the movability of the adjusting portion relative to the base portion is locked or impeded and in an unlocking position the adjusting portion is movable relative to the base portion.
In a further variant the receiving element for the reel of the constant-force spring is fastened to the receiving element fastening geometry positively and/or non-positively, e.g. with a clip connection and/or the first helical spring fixing element is fastened to the first helical spring fixing element fastening geometry positively and/or non-positively, e.g. with a clip connection and/or the second helical spring fixing element is fastened to the second helical spring fixing element fastening ge-ometry positively and/or non-positively e.g. with a clip connection and/or the first pneumatic fixing element is fastened to the first pneumatic fixing element fastening geometry positively and/or non-positively e.g. with a clip connection and/or the sec-ond pneumatic fixing element is fastened to the second pneumatic fixing element fastening geometry positively and/or non-positively e.g. with a clip connection and/or the fastening device for fastening an electric motor is fastened to the electric motor fastening geometry positively and/or non-positively e.g. with a clip connection.

In an additional variant the automobile comprises a body and/or a drive motor, in particular an internal combustion engine and/or an electric motor.
In a further embodiment, the adjusting portion is movable relative to the base portion in the longitudinal direction of the automobile so that the seat surface of the seat portion in different positions of the adjusting portion has a different extension in the longitudinal direction of the automobile, in particular the extension of the seat sur-face in the longitudinal direction differs by at least 5%, 10%, 20%, 30% or 40%.
Exemplary embodiment of the invention are described in detail hereinafter by refer-ence to the appended drawings. In the figures: Fig. 1 shows a side view of an automobile, Fig. 2 shows a longitudinal section of the vehicle seat in first exemplary em-bodiment, Fig. 3 shows a longitudinal section of a base portion and an adjusting portion of a vehicle seat in a second exemplary embodiment, Fig. 4 shows a longitudinal section of a constant-force spring with a drum as a receiving element for a reel of the constant-force spring of a vehicle seat in a third exemplary embodiment Fig. 5 shows a longitudinal section of the base portion and the adjusting por-tion of the vehicle seat in a fourth and fifth exemplary embodiment and Fig. 6 shows a longitudinal section of the base portion and the adjusting por-tion of the vehicle seat in a sixth exemplary embodiment.
An automobile 2 (Fig. 1) having a body 19 as well as a drive motor, for example, an internal combustion engine and/or electric motor, is used to accommodate persons within an interior 3 of the automobile 2. Located inside the interior 3 are vehicle seats 1, for example, two front seats 1 and three back seats 1.
The vehicle seat 1 (Fig. 2). for example, the front seat 1 comprises a seat portion 5 and a back portion 10. The seat portion 5 comprises a two-part seat cushion 6 made of an elastic material, namely foam, and the seat cushion 6 is fastened to a base portion 14 and an adjusting portion 15 which is substantially plate-shaped. A first seat cushion 8 is fastened to the adjusting portion 15 and a second seat cushion 8 is fastened to the base portion 14. A seat cover 13 made of fabric or leather is 10-cated on an upper side of the seat cushion 6. A seat surface 9 on the seat cover 11 is used for direct contact of a person on the vehicle seat 1. The base portion 14 is fixed on a shell structure 16 and the shell structure 16 is fastened with a seat holder 18 on the body 19. Optionally the vehicle seat I can be formed on the seat portion 5 without a separate shell structure 16 as a separate component so that the base por-tion 14 also forms the shell structure 16 (not shown). Similarly the back portion 10 comprises a back cushion 11 made of an elastic foim and the seat cover 13 which is located on an upper side of the back cushion 11 and forms or delimits a back sur-face 12. The back cushion 11 is also fixed by means of the shell structure 16. By means of a connecting device not shown the shell structure 16 on the seat portion 5 is connected to the shell structure on the back portion 10 and at the same time the back portion lOis also pivotable about a pivot axis 17.
The vehicle seat 1 comprises a seat depth adjuster 4 since the adjusting portion 15 is mounted movably relative to the base portion 14 with a mounting 21. The mount-ing 21 is configured, for example, as a hollow tube inside which a rod is located (Fig. 2) or as a rail on which rollers are mounted or roll (not shown). The vehicle seat 1 is fastened by means of the seat holder 18 on the body 19. At the same time, by means of a further additional adjusting device, not shown, the entire vehicle seat 1 can be moved in a longitudinal direction 20 relative to the remaining automobile 2.
This movement of the entire vehicle seat 1 and therefore also of the base portion 14 is however not taken into account subsequently. The base portion 14 is in this re-sped considered to be stationary and immovable and only the adjusting portion 15 is configured as movable relative to the base portion 14. As a means 22 for applica-tion of an adjusting force to the adjusting portion 15 for movement of the adjusting portion 15, the vehicle seat 1 shown in Fig. 2 has only movement member 48 as a handle 49 or a lever 50. Further means 22 for additional arrangement on the vehicle seat I shown in Fig. 2 are shown in the following figures.
Figure 3 shows a second exemplary embodiment for the partially depicted vehicle seat 1 with a constant force spring 23 as the means 22 for application of an adjust-ing force to the adjusting portion 15 in addition to the handle 49. A receiving element 29 is used for mounting or receiving a reel 31 of the constant force spring 23. Out-side the reel 31 a band 32 of the constant force spring 23 is fastened with a fixing element 35 on the base portion 14. In the second exemplary embodiment shown in Fig. 3, the receiving element 29 has a recess 34 inside which the reel 31 is dis- posed. On the receiving element 29 as the component with the recess 34 a com-plementary counterfastening geometry 53 is formed as a latching projection and a receiving element fastening geometry 30 is formed as a latching recess on the ad-justing portion 15. The complementary counter-fastening geometry 53 is fastened positively and non-positively on the receiving element fastening geometry 30 on the adjusting portion 15 by means of a clip connection 51. The reel 31 of the constant force spring 23 has the tendency to automatically roll up, i.e. to introduce the band 32 outside the recess 34 into the recess 34 through the unrolling of the reel 31 and as a result of the stationary base portion 14, an adjusting force is applied to the ad-justing portion 15 by the constant force spring 23 according to the diagram in Fig. 3 to the right onto the adjusting portion 15 so that as a result of the adjusting force applied by the constant force spring 23 to the adjusting portion 15, the adjusting portion 15 is moved to the right in the longitudinal direction 20 and as a result, the extension of the seat surface 9 is reduced. The vehicle seat I additionally has a locking device 46 (only shown in Fig. 2) with an actuating member 47, namely a handle 49 or a lever 50. By means of the locking device 46, upon actuation of the actuating member 47 the locking device 46 can be unlocked so that as a result the adjusting portion 15 is movable in the longitudinal direction 20 relative to the base portion 14 and in a locking position of the locking device 46 the movability of the adjusting portion 15 relative to the base portion 14 is impeded. The actuating mem- ber 47 serves at the same time as actuating member 48 for applying a manual ad-justing force to the adjusting portion 15. For increasing the extension of the seat surface 9 in the direction of the longitudinal direction 20, an adjusting force directed towards the left according to the diagram in Fig. 3 therefore has to be applied to the adjusting portion 15 by means of the handle 49or the lever SOso that this can be moved to the left against the adjusting force applied by the constant force spring 23 to the adjusting portion 15 and then the locking device 46 is locked with the actuat-ing member 47. For moving the adjusting portion 15 to the right, the locking device 46 merely needs to be unlocked with the actuating member 47 so that as a result the adjusting portion 15 is automatically moved to the right by the constant force spring 23 according to the diagram in Figs. 2 and 3. The adjusting portion 15 and the base portion 14 each have an upper contact surface 52 (Figs. 2 and 3) on which respectively the first seat cushion 7 and the second seat cushion 8 are arranged (Fig. 2).
Figure 4 merely shows a further exemplary embodiment for the configuration of the receiving element 29 for the reel 32, namely the configuration of the receiving ele-ment 29 as a drum 33 or a drum web 33 on which the reel 31 of the constant force spring 23 is mounted. The receMng element 29 additionally has boundary surfaces for delimiting the movement of the reel 31 perpendicular to the plane of the drawing from FIgs. 3 and 4.
Figure 5 shows a fourth and fifth exemplary embodiment for the configuration of the means 22 or the vehicle seat 1. Hereinafter substantially only the differences from the exemplary embodiment described in Fig. 2 and 3 are described. In a configura-tion of the means 22 as a helical spring 24, the helical spring 24 having a first screw fixing element 36 with a complementary screw fixing geometry 53 on the first screw fixing element 36 is fixed on a first screw fixing element fastening geometry 37 on the base portion 14. Another end of the helical screw 24 is fixed on the adjusting portion 15 by means of a second screw fixing element 38. For this purpose, in simi- lar manner the second screw fixing element 38 has the complementary counterfas- tening geometry 53 by means of which the second screw fixing element 3Bis fas-tened on a second screw fixing element fastening geometry 39 on the adjusting portion 15. In a configuration of the means 22 as a pneumatic element 26, e.g. a pneumatic bladder 27 or a pneumatic piston 28 inside a pneumatic cylinder, the pneumatic element 26 is fixed in similar manner to the helical spring 24 by means of a first pneumatic fixing element 40 on a first pneumatic fixing element geometry 41 on the base portion 14 and at the other end of the pneumatic element 26 said ele-ment is fixed with a second pneumatic fixing element 42 on a second pneumatic fixing element geometry 43 of the adjusting portion 15. The first and second pneu- matic fixing element 40, 42 each also have a corresponding complementary coun-terfastening geometry 53. The exemplary embodiment of the vehicle seat I shown partially in Fig. 5 also comprises the locking device 46 with the actuating member 47 as well as the movement member 48 (not shown in Fig. 5).
Figure 6 shows a sixth exemplary embodiment of the vehicle seat I or the means 22. Substantially only the differences from the exemplary embodiments described in Figs. 2 and 3 will be described hereinafter. An electric motor 25 is used as means 22 for applying an adjusting force to the adjusting portion 15. A threaded rod 54 is fastened to the electric motor 25 and can be set in rotational movement about a longitudinal axis of the threaded rod 54. A spindle nut 55 is screwed onto the exter-nal thread of the threaded rod 54 and the spindle nut 55 is fastened or fixed on the adjusting portion 15 by means of a spindle nut fixing element 56. For this purpose the spindle nut fixing element 56 has a complementary counter-fastening geometry 53 and the adjusting portion 15 has a spindle nut fixing element fastening geometry 57 and the complementary counterfastening geometry 53 is fastened on the spindle nut fixing element fastening geometry 57 by means of a clip connection 51. The electric motor 25 is fastened to a fastening device 44 on the base portion 14. For this purpose the fastening device 44 has the complementary counter-fastening ge-ornetry 53 which is fastened in an electric motor fastening geometry 45 on the base portion 14 positively and non-positively by means of a clip connection 51. Unlike the above exemplary embodiments, the vehicle seat 1 has no locking device 46 and also no movement member 48 separately since a locking device 46 can already be provided by means of the electric motor 25 and the spindle drive with the spindle nut 45 and the threaded rod 54 and the movement of the adjusting portion 15 relative to the base portion 14 in both movement directions of the longitudinal direction 20 can be executed by the electric motor 25 since this can set the threaded rod 54 into a rotational movement in two opposite directions of rotation so that as a result, no movement member 48 is required in order to be able to manually apply an adjusting force mechanically by hand to the adjusting portion 15.
The receiving element 29 in a one-part configuration on the adjusting portion 15 is fastened on the adjusting portion 15 without the receiving element fastening geome- try 30 and without the complementary counterfastening geometry 53 in another ex-emplary embodiment not shown. This also applies to the first screw fixing element 36 which, in another exemplary embodiment not shown with a one-part configura-tion on the base portion 14 requires no complementary counter-fastening geometry 53 and also no first screw fixing element fastening geometry 37 since the first screw fixing element 36 is formed in one part on the base portion 14. This also applies for other exemplary embodiments not shown similarly for the second screw fixing ele-ment 38 and/or the first pneumatic fixing element 40 and/or the second pneumatic fixing element 43 and/or the fastening device 44 for the electric motor 25.
When viewed overall, substantial advantages are associated with the vehicle seat 1 according to the invention and the method for manufacturing the vehicle seat I ac-cording to the invention. Different means 22 for applying the adjusting force to the adjusting portion 15 can be mounted or fixed on the identical base portion 14 and/or on the identical adjusting portion 15 so that as a result in a modular design with identical base portions 14 and identical adjusting portions 15 most diverse means 22 can be mounted or fastened on various vehicle seats I for movement of the ad- justing portion 15. The costs for the manufacture of the vehicle seat I and the re-quired logistic expenditure for different components can thereby be substantially improved because the identical base portions 14 and the identical adjusting portions can be fabricated in large numbers of items for the vehicle seats I with the vari-ous means 22.
At least one exemplary embodiment has been described, where it should be noted that a large number of variants to this exist. It should also be noted that the exem-plary embodiment or the exemplary embodiments are only examples and therefore it is not intended to restrict the scope of protection, the applicability or enablement or the structure in any way. The aforesaid description gives the person skilled in the art suitable instructions for executing at least one exemplary embodiment.
