Description

The The invention relates to a belt integral seat with a longitudinal adjustment, which has two pairs of rails, with a base, the two front pivot supports, two rear pivot supports and two of these pivot supports having worn side parts, with a backrest, over a Backrest joint is connected to the side panels, and with a buckle.

Gurtintegralsitze of this kind are for example made US 5,390,982 ; US 5,599,070 ; US 5,390,982 and US 5,988,759 known. In Gurtintegralsitzen the pelvic part of the seat belt extends from a lock towards a fastening on the lock-facing rail pair, as is usual. The shoulder strap extends from the buckle to a point of deflection in the region of the upper edge of the backrest and runs down from there, where it is connected to a part of the seat, for example a crossbeam. Unlike the normal automobile seat, the shoulder strap is not attached to the B-pillar. In Gurtintegralsitz all belt forces are absorbed only on the base and transferred to the floor pan of the vehicle.

One Belt integral seat must meet significantly higher mechanical requirements than a conventional seat. Especially on the backrest are significantly higher forces in the Lower frame initiated than before, since now no more forces introduced into the B-pillar become. Accordingly, many must Components of the seat stronger to be executed so far, for example, the side panels, the pivot supports, etc. Also, the retractor is no longer in the B-pillar, but arranged in the vehicle seat itself.

To The prior art, the side panels are double-walled, as more or less closed boxes executed. The inner cavity of these boxes will not for Components used. The box construction high strength is achieved. But there is room for Components lost.

Here uses the invention. She has made it her goal, the construction a Gurtintegralsitzes space-saving and under optimal use to design the material used.

Accordingly, it is Object of the invention, the Gurtintegralsitz initially mentioned Art to continue to form that its components space-saving and are easier to produce and optimal to the respective, on they adaptable forces are. Starting from the belt integral seat of the aforementioned This object is solved in a way that the lock-away Side part bowl-shaped is formed, wherein it has a bottom and a circumferential profile edge having. In this case, the lock-facing side part is preferably the vehicle outside Side panel.

The well-shaped Side panels can be constructively designed so that they have sufficient strength exhibit. about she is wearing the backrest, so that the corresponding forces must be recorded by them. Be about the pivot supports the accidental forces in the longitudinal adjustment initiated. Due to the shell construction of the side panels, it is possible individual components to accommodate in the interior of the respective shell, for example at least one electric motor, manual drive units, etc. The revolving Edge stiffens and ensures that the floor is actually the accident-related forces picks up and does not buckle sideways. The soil can be shaped be used to For Building elements to create space.

Further Advantages and features of the invention will become apparent from the other claims and to the following description of four non-limiting ones Understanding embodiments of Invention, which are explained in more detail below with reference to the drawing. In the drawing show:

The belt integral seat has a longitudinal adjustment with two pairs of rails, each with a bottom rail 20 and a seat rail 22 exhibit. The floor rails 20 are each on a floor group 24 attached an otherwise not shown motor vehicle. The rails 22 . 24 each seat side are identical. On the more heavily loaded left seat side are additional reinforcement profiles 26 on both rails 22 . 24 attached. They interlock with each other and do not become noticeable in normal operation, only in case of accidental loads come the mutual entanglements into engagement. Alternatively, the rails 22 . 24 be reinforced by additional sheets.

For the purposes of this application, front is to be understood in the positive x-direction, that is to say in the direction of view of a user of the motor vehicle seat. Similarly, left is in positive y-direction, right is in negative y-direction. Above is to be understood in the positive z-direction. The vehicle outside-side of the seat is usually the door side, at least in two-seated vehicles, where the seatbelt integral seat is a front seat. A buckle 28 is usually located on the inside, so facing away from the door side.

Above the longitudinal guide is a base frame, which is supported by the longitudinal guide. It has a console on the left side of the seat 30 , on the right side of the seat two bearing blocks, which take over the corresponding function. From them protrude front pivot supports 32 and rear pivot supports 34 upwards and are articulated. The pivot supports are at the top, each with a side part 36 . 38 hinge-linked. Between the left side part 36 and the right side panel 38 is a seat shell 77 , she is at the back of the sides 36 . 38 pivotally hinged and can in its front area by a NV-adjusting device 40 be adjusted in height, so that their overall angular position is adjusted. The two rear pivot supports 34 are through a rear crossbar 42 connected together into a unit which is substantially H-shaped.

The side parts 36 . 38 are trough-shaped. You have a floor 44 which essentially runs in one plane, namely in the xz plane. From this ground 44 a circumferential profile edge jumps 46 in front. He points from the buckle 28 away, so both side parts are referred to as left and to the side as open; from the buckle 28 turned away. The two side parts 36 . 38 are integrally molded from a sheet metal part. The profile edges 46 jump 10 to 30 mm, in the y direction before. It is possible that in the foremost area of the side panels 36 . 38 at least before the upper point of articulation 66 the front pivot supports 32 , the profile edge 46 is less formed or does not exist, because there are only small loads on the side panels 36 . 38 act.

The left side part 36 has a much higher strength than the right side part 38 , Preferably, the left side panel made of sheet metal with more than 3 mm thick sheet metal. In contrast, the thickness of the right side panel 38 about 2 mm. The left side part 36 can absorb at least 50%, preferably 100% larger forces than the right side panel 38 , Preferably, the bottom is not flat, but shaped, it is in the same direction, in the profile edge 46 protrudes, molded. It is not formed in the other direction, that is, in the negative y direction, so it stays within a plane passing through the corners of the profile of the side parts 36 . 38 is defined.

In side view, the side parts are substantially L-shaped, wherein the short L-leg projects approximately in the z-direction upwards. He carries in his upper area a backrest fitting 48 , To the pivot axis of a backrest 50 with the side parts 36 . 38 connected is. It is only on the left seat side a backrest fitting 48 provided, which is adjustable and lockable. On the right side of the seat, so the side of the buckle 28 , only a passive pivot joint is formed. The only one Lehnengelenkbeschlag 48 It is designed to withstand all accidental forces affecting the backrest 50 can take effect. It is located substantially below a belt deflection 52 at the top, left corner of the backrest 50 attached with this.

The backrest 50 has a sturdy U-shaped frame, which is bent from a strong tube profile and is open at the bottom. The backrest 50 also has two side cheeks, which are attached to the outside and side of the legs of this U-profile and are cross-linked at the bottom of an apron. On these side bolsters is also the attachment in the area of the backrest fitting 48 or the passive joint. Due to the one-sided backrest fitting 48 it is not necessary to provide a shaft connecting the two sides. In an alternative, the right seat side has its own adjustable backrest fitting 48 However, which can absorb only about one-third as high torques as the backrest hinge fitting 48 the left side. In this alternative, the two Lehnengelenkbeschläge a shaft are connected to each other to synchronize.

The two rear pivot supports 34 be can be found between the side panels 36 . 38 , The front pivot supports 32 are each on the open side of the side panels 36 . 38 articulated, so in the embodiments on the left side of the seat.

The Description refers to that shown in all figures Seat, which is a driver's seat for left-hand drive Is motor vehicles. The corresponding passenger seat is mirror-symmetrical constructed, the plane of symmetry is in the vehicle center in the x-z plane.

The Längsverstellvorrichtung is locked in a conventional manner by means of a manual locking device. She has a hand lever 54 pivotable about a front axle synchronizing the two locking devices on both sides of the seat. In the motor design is in the interior profile space of the rails 20 . 22 an arrangement of rack and pinion or spindle and spindle nut provided, which is indicated by a first electric motor of the continuous shaft. This too is state of the art.

The height adjustment also takes place according to the prior art via a dental arch, with the left, rear pivot support 34 connected is. He combs with a pinion, in the associated side panel 36 is stored. This is via a drive device 58 , For example, with Klemmrollenensperrgetriebe, operated. This drive device 58 located in the tub interior of the left side panel 36 , at least partially. The dental arch has a relatively large thickness, for example, a material thickness of 5 mm and is also reinforced by a toothed addition of about 4 mm thickness. So a high strength is achieved.

In the motor alternative is the pinion with a second electric motor 60 connected, he is also at least partially in the tub interior of the left profile part 36 arranged. It is crucial that in the manual and motor alternative each arch and pinion, also pinion bearing in the side panel 36 , stay the same. The locking of the height adjustment of the side parts 36 . 38 takes place on one side, only on the castle facing away from the seat side, so the left seat side in the embodiment. Through the rear crossbar 42 If this is done firmly, the setting is transmitted to the passive right side of the seat. This will drive devices on the right side of the seat 58 saved.

The locking of the backrest 50 in case of manual execution via the backrest fitting 48 , Again, the lock is provided only on the left side of the seat. In the motor alternative, which also works only on one side on the left seat side, is a third electric motor 62 provided, which is located in front of the left leg of the U-profile and on the inside of the left side cheek, it extends upward. The drive takes place according to the prior art.

The adjustment of the height of the seat leading edge is relative to the side panels 36 . 38 , This has the advantage that the corresponding adjustment device does not have to be designed for receiving the entire accident-related forces. The accident-related forces are on the pivot supports 32 . 34 introduced into the longitudinal guide. The height adjustment of the seat front edge, so NV setting device 40 , can be omitted in this way, without the construction of the side panels 36 . 38 and the pivot supports 32 . 34 to have to change. The variants are structurally very easy to implement. Specifically, the NV setting device has 40 a front bridge 64 , which also forms the seat leading edge and is essentially constructed of a pipe section and two side wings. The latter are at the front of the sides 36 . 38 in a pivot point 66 hinged. The pivoting position of the side wings can in a conventional manner via a setting gear with handle 68 be set.

In the motor version is a fourth electric motor 70 provided, even before the first electric motor 46 and is arranged in the vicinity. Again, the adjustment takes place only on the belt buckle 28 facing away from the seat, so here on the left side of the seat. The right side of the seat is passively adjusted.

At the left seat rail 22 is an attachment point at the back 72 for one end of a seatbelt 74 intended. From there the safety belt runs 74 as lap belt on the other, right seat side to the buckle 28 and from this as the upper belt for belt deflection 52 , From there it runs inside the backrest 50 down to a retractor 76 (see eg 3 ), which in the embodiment shown substantially above the rear cross member 42 is arranged.

To increase their strength, the front pivot supports 32 U-shaped, its profile is open in negative x-direction. To the strength of the left front pivotal support, which is particularly stressed during accidents 32 To increase, the profile may also be box-shaped, so be closed the U-profile. Furthermore, to increase the rigidity of a front cross member 84 be provided, which is fastened approximately in the middle of the front pivot support and connects the two pivot supports together. The rear pivot supports 34 are essentially flat sheet metal parts, but of sufficiently thick material. It may be necessary for reasons of strength, the left rear pivot support 34 as a U-profile, like this 5 ersicht is.

In the following, particular reference will be made to those features of the further embodiments that are different from the above description, which refers to the first embodiment, but is still to be understood generally. In the second embodiment of the 4 and 5 is the retractor below a seat pan 77 , approximately in the middle, arranged. It is located approximately at the height of the longitudinal guide. He is about a tension strut 78 with the right side part 38 connected, approximately in the calculation of the upper pivot point 66 the front, right swivel support 32 , It is not an NV setting device 40 intended. The two side parts 36 . 38 are over a front bridge 86 connected with each other. It forms the structure for the front seat edge. The rear crossbeam 42 runs in the connecting line of the upper pivot points of the rear pivot supports 34 , A torsion spring is used as a seat lift spring essentially in this traverse 42 accommodated.

The third embodiment according to the 6 to 8th Corresponds essentially to the first embodiment, the difference lies in the motorization of the seat.

According to the fourth embodiment 8th is shown a motor seat, the similarity with the mechanical seat after the 4 and 5 , So the second embodiment has. It is not a seat shell now 77 intended. The rear crossbeam 42 is slightly cranked. The electrical training for the longitudinal adjustment by means of the first electric motor 56 , for the height adjustment by means of the second electric motor 60 and the backrest adjustment by means of the third electric motor 62 is largely in accordance with the third Ausfüh tion example. The two side parts 38 are ahead over the front bridge 86 connected, which also forms the front edge of the seating area. A tilt adjustment is not provided. The left front pivot support 32 has a U-profile that is open to the rear, while the right front pivot support 32 has a forward open U-profile.

The 9 and 10 show examples of the arrangement of parts of the adjustment device for the seat height. Shown is a sectional view through the left side panel 36 in the area of a pinion 88 , To recognize is the ground 44 of the side part 88 and the profile edge 46 , The profile edge 46 jumps ahead in its lower part than in its upper part, which is the upper edge of the bottom 44 follows. The difference is at least 2, preferably at least 5 mm. This will be in the upper area of the side panel 38 Saved space. Accordingly, the procedure also applies to the other side part. The pinion 88 is in the side part 38 stored. It's with a gearbox 90 the drive device 58 connected, which is designed for example as a clamp lock and according to the prior art. A hand lever for the operation is not shown.

10 shows the motor equivalent. It can be seen that the side part 36 and pinion 38 identical to the manual version. It is now another gear with electric motor 60 intended. This gear fits even better than it already gear 90 according to 9 does, enter the tub room. Also the electric motor 60 is housed to a considerable extent within the tub.

An essential advantage of the Gurtintegralsitzes described lies in its modularity. The manual drive devices 58 can be replaced with the electrical without significant structural changes have been made, this has been described above. Thus, the handwheel for manual backrest adjustment can be replaced by the electric drive by means of the third electric motor 62 , The same applies to the other adjustment.
