The present invention relates to a motor vehicle rear seat with foldable Backrest and lowerable seat part, the backrest creating a Loading area on the seat part is foldable.
Rear seats which - without having to be removed - offer the option of an additional one to create loading space adjoining the luggage compartment are from the state of the art Technology known. They are mainly used for minibuses, minivans etc. Application. So that the additional loading area created essentially on the Level of the luggage compartment floor, it is necessary that the seat in its Builds the loading position as flat as possible. In this regard, the upholstered seat part of the Seat difficulties as it hinders the desired flat folding of the backrest is.
To solve this problem, there are seats in which the seat part in front of the backrest flaps can be removed from the folding area (DE 43 40 446 C2, US Pat. No. 5,730,496). Other Constructions provide that the entire seat by one in the front area of the Seat part arranged on the vehicle floor transverse axis can be pivoted forward (DE-OS 28 49 985, DE 44 22 920 Al). The present invention goes against the solutions outlined above from a prior art, in which the seat part lowered and the backrest is folded onto the lowered seat part, such seats are known from US 4,805,953. This document is considered to be the closest prior art. The lowerable is supported in this solution Seat part in its front area on a longitudinally mounted on the vehicle floor pivotable swing arm, the forward displacement of the seat part relative to Folding axis of the backrest takes place. The object of the invention is to provide another seat to make this concept available.
This object is achieved with a seat which has the features of claim 1.
By simultaneously advancing the seat part relative to the lowering The backrest folding axis comes in with its upper area, the front of the backrest which she builds relatively thin compared to her lower area, on the seat part Investment. As a result, the back of the backrest forms an almost flat loading area. Without moving the seat part forward, the backrest would come before it was reached the desired level loading surface position in contact with the seat part, i.e. the The back of the backrest would be more or less sloping forward and upward.
Further advantageous embodiments of the present invention emerge from the subclaims.
a basic side view of a rear seat in the use position,
2 shows a detail A according to FIG. 1 on an enlarged scale,
2, showing the seat at the beginning of a backrest folding process, and
a side view of the back seat with the backrest fully folded.
The motor vehicle rear seat shown in the drawing (hereinafter referred to as "seat") a seat part 1 and a backrest 2 with a Headrest 3, which is guided via rods 4 in the backrest 2 is. The seat is not adjustable on the shown vehicle floor arranged. As usual, a system of two parallel bottom and top rails 6 provided, the lower rails 5 on the vehicle floor are attached and the top rails 6 in the Bottom rails 5 run.
The backrest 2 is on both sides with their Backrest frame belonging side parts 7 pivotally Adapter 8 struck. To this end, locking adjusters 9 are provided, that belong to the state of the art and therefore here not explained further. Define the locking adjuster 9 the folding axis 10 of the backrest 2.
To adjust the inclination of the backrest 2 are to release the locking adjuster 9. This is done using a arranged on the side of the backrest 2, only symbolically shown lever 11, each via one Cable 12 is connected to the locking adjusters 9. To a seat occupant can release the locking adjuster 9 Giving or pushing his back against the backrest 2 biased forward by springs, not shown is the backrest inclination according to his needs to adjust.
The seat part 1 is in its front area mounted on a rocker 13. This rocker 13 supports themselves at one end, forming a lower one Axis of rotation 14 on trestles rising from the top rails 6 15 and is at its other end forming one upper axis of rotation 16 hinged to the seat part 1.
The seat part 1 has a not shown Steel frame, one in the rear area Pin 17 protrudes laterally. Pass through these bolts 17 one provided in the adjacent adapter 8 Slot 18, which is parallel to the vehicle floor and extends immediately above the top rails 6 with which the adapter 8 are rigidly connected.
With the seat in the position of use (Fig. 1 and 2) the bolts 17 are located at the rear end of the elongated holes 18 and are each engaged by a pawl 19, which can be pivoted about an adapter-fixed pin 20 is arranged. This lock prevents that the seat part 1 unintentionally move forward can. By actuating the lever 11, the pawls 19 can be solved via cables 31.
Below are those for the relocation of the Seat part 1 required components described. This can be identical on both sides of the seat or only be present on one side of the seat. following these components are only explained for one seat side.
Below the folding axis 10 of the backrest 2 an elongated hole 21 is provided in the side part 7 thereof, which lies on a circular arc around the folding axis 10 and is penetrated by a bolt 22 which leads to a rigid coupling element 23 belongs. The length of the elongated hole 21 and the position of the bolt 22 in the slot 21 are dimensioned so that the bolt 22 in the inclination adjustment of the Backrest 2 is not in the normal setting range Ends of the elongated hole 21 strikes, making the possible Tilt adjustment range of the backrest 2 is limited would.
A pawl 26 is located above the elongated hole 21 mounted on a side part fixed bolt 27, which by a compression spring 28 against an adapter-fixed link 29 is biased. This pawl 26 is under this spring tension with their back on the backdrop 29 on and has a semicircular recess on its front 30 for receiving the bolt 22, as later is explained.
The coupling element 23 extends into the front area of the seat part 1 and is at this end designed as a rack 24 with a gear 25 Combing which rotatably on the lower axis of rotation 14 of the Swingarm 13 sits.
Below is the transfer of the seat its use position shown in Figs. 1 and 2 in its loading position (Fig. 4) described. To do this first once by means of the lever 11, i.e. by pulling the cables 12 and 31, the locking adjuster 9 and that Seat part 1 pawls locking in its position of use 19 to solve. The backrest 2 can now due to Fold the preload forward about the folding axis 10. By this movement moves the bolt 22 of the coupling element 23 in slot 21 relatively clockwise, until it bears against the front end of the elongated hole 21. simultaneously also pivots the backrest-fixed pawl 26, which at this movement with 'its back on the backdrop 29 of the adapter 8 runs along and the moment the Bolt 22 strikes the end of the elongated hole 21 through the upward curved shape of the backdrop 29 with its recess 30 in engagement with the bolt 22 of the Coupling element 23 is pressed.
Through the contact of the bolt 22 on the slot wall is now the coupling element 23 on the other Folding path of the backrest 2, on which the latch 26 remains in engagement with the bolt 22, taken along, i.e. moved backwards. As a result, the gear 24 and thus the lower axis of rotation 14 of the rocker 13 in the counterclockwise direction driven, i.e. the swingarm 13 pivots forward, whereby the seat part 1 relative to Folding axis 10 moved forward and lowered at the same time becomes. At the end of the folding process lies in Fig. 4 shown situation before.
It can be clearly seen that the bolt 17 in Elongated hole 18 has moved completely forward. there it goes without saying that the slot 18 in its Length is dimensioned so that the desired advance the seat part 1 is not hindered.
4 shows that the backrest 2 here, of course, on the highest parts of the seat upholstery, the side cheeks 32 rests. Due to the Forward movement of the seat part 1 is in comparison with the lower area of the backrest 2 relative thin top area on the side cheeks 32, whereby the back of the backrest 2 a substantially level, i.e. loading area parallel to the vehicle floor 33 forms. 4 also becomes it is clear that if something is not or not so far advanced Seat part 1 the backrest 2 more or less obliquely would stand up and forward.
When the backrest 2 is folded back into the use position the pin 22 is taken along by the pawl 26, i.e. the coupling element 23 is advanced. Thereby pivots the rocker 13, mediated by the Rack 24 and gear 25 about their lower axis of rotation 14 back to their use position. When this reaches is the pawl 26 gives the bolt 22 of the coupling element 23 free again, and the pawls 19 snap into the Bolt 17, whereby the seat part 1 in its position of use is secured.
