11 the arrangement of 9 in the "easy-entry position", and

12 the arrangement of 9 in from a different perspective.

According to the present embodiment, a seat 1 , which is used as the outside rear seat in a van, a seat part 3 and a backrest 5 on, relative to the seat part 3 to a trained by two multi-part fittings 7 extending pivot axis S is pivotable. The seat 1 is by means of two below with the seat part 3 over several wings 9 connected, mutually parallel first rails 11 and associated, vehicle-structural, second rails 13 which are the first rails 11 embrace, attached in a known per se in the longitudinal direction of the vehicle slidably on the ground. The adjustment is for normal use via a stop 13 ' after from the limited.

The rest 5 of the seat 1 can according to the embodiment both in a loading floor position, in which the backrest 5 about the pivot axis S forward on the seat part 3 pivoted, as well as - in conjunction with an ancestor of the seat 1 - be placed in the "easy-entry position", in which the backrest 5 under Vorschwenken about the pivot axis S and the seat part 3 placing it around one in the front area of the seat part 3 arranged seat pivot axis closest possible to the seat 1' the previous row of seats is positioned in order to provide the largest possible entry or exit area for the seat arranged behind it (not shown). The normal position of use of the seat 1 is in 1 and the "easy entry position" in 2 shown schematically.

The seat 1 has five wings on each side 9 on, with the lower base rocker 9a and the first rail 11 are firmly connected and define the substructure. At the front end of the lower base swingarm 9a is a shorter, front swingarm 9b mounted pivotally, on which in turn an upper rocker 9c , which with the seat part 3 is fixedly connected, slightly spaced from its front end is pivotally mounted. The rear end of the upper swingarm 9c is pivotable with a kinked trained swingarm 9d connected with their other end to the backrest 5 is mounted pivotally above the pivot axis S. The area between the connection of the bent rocker 9d and the lower base swingarm 9a , ie the fifth swingarm, is through an area of the backrest 5 educated. The wings 9 can - with appropriate design - adjustability of the seat part 3 allow, such as a height adjustability and / or tilt adjustability, but present is only a change in the position of the seat part 3 for the so-called "easy entry position" (see 2 ) provided, for which the upper rocker 9c and the bent swingarm 9d after unlocking, in which a locking latch not shown is pivoted from its locking position can be set up with the ends connected to each other (see 2 ). The position of the other wings changes accordingly, ie the front wing 9b is with its upper end slightly backwards and the backrest 5 tilted forward. Further, the seat is 1 in his foremost position.

For the adjustability of the seat 1 in the longitudinal direction of the vehicle is a in the front area of the seat 1 below the seat part 3 arranged, swiveling bracket 15 provided, at the ends of a seat rail locking device 17 is provided. The coat hanger 15 allows a known, manual unlocking of the seat rail pairs by pulling up the bracket 15 and a move of the seat 1 within a predetermined range in the longitudinal direction of the vehicle, as long as the bracket 15 pulled up and thereby the seat rail locking device 17 is kept out of engagement. The coat hanger 15 is here on a stiffening transfer bracket 19 appropriate, which when pulling up the strap 15 also pivoted This transmission bracket 19 is at the on the first rail 11 fixed, lower base swingarm 9a pivotally mounted about a defined by the bearing pivot axis S19, which at the same time the pivot axis of the bracket 15 forms.

The adjustment in the case of a use position of the seat 1 by an occupant will be forward by abovementioned stop 13 ' limited, to which a surface 21 ' comes into abutment, which on a rotatably mounted counter element 21 is trained.

For another procedure of the first rail 11 relative to the second rail 13 , as it is required for the "easy entry position", there is a pivoting of the counter element 21 so the stop 13 ' the counter element 21 can happen. The counter element 21 is for this purpose on the arranged in the direction center of the seat side of the second rail 13 pivotally mounted on a corresponding formed tab and is about a trained thereon arm 21 '' with the soul 25 ' a first Bowden cable 25 in conjunction, leaving the area 21 ' at a train of the first Bowden cable 25 on the arm 21 '' under pivoting of the counter element 21 raised about the pivot axis S21 and over the stop 13 ' can be performed. Thus, the seat can 1 get into an "easy entry position" in which it is positioned further forward than in a normal position of use with einitzendem occupant. At the same time, another surface works 21 ''' of the counter element 21 , which is in contact with a lever arm 19 ' of the transmission bracket 19 is on the lever arm 19 ' and thereby causes a rotational movement of the transfer bracket 19 , which in turn a pivoting movement of the bracket 15 triggers, leaving the seat rail locking device 17 disengaged and the first rails 11 are freely displaceable in the longitudinal direction. Here, the first Bowden cable runs 25 slightly offset laterally in an approximately horizontal direction and above the lever arm 19 ' , By pulling the first Bowden cable 25 is thus the same function as when pulling up the bracket 15 reached, in addition, however, still the stop 13 ' as a result of the pivoting of the counter element 21 be overcome.

It should be noted that the lower end of the shell of the first Bowden cable 25 in a manner known per se on a holder 27 is supported, which differs from the lower base swingarm 9a extends out and has a C-shaped end, through which the soul 25 ' runs while the sheath is arranged on one side. The other end of the first Bowden cable 25 is on a first arm 29 ' a first control disc 29 mounted, which is pivotally mounted, wherein the bearing underestimated, so with the lower base rocker 9a connected is.

The first control disc 29 is rotatably mounted, in this case about an axis, which with the pivot axis S of the backrest 5 coincides, being on the same arm of the first control disc 29 two more Bowden cables 31 are attached, which serve for unlocking arranged on both sides of the seat pawls (not shown), which are released for ingestion of the "easy-entry position". These pawls are arranged on the sides of the seat and fix in the locked state, the position of the wings 9c and 9d relative to each other, in the released state, the interconnected ends of the wings 9c . 9d moved upwards (see 2 ), whereby simultaneously the rear end of the seat part 3 is raised while the forward projecting front end of the seat part 3 is lowered.

The first control disc 29 can - alternatively to the arrangement described above - be arranged at a different location, so that their pivot axis does not coincide with the pivot axis S, however, the arrangement on the pivot axis S has the advantage that the backrest inclination has no effect on the starting position of the first control disk 29 Has. The first control disc 29 is in particular independent of the arranged in the same axis fitting 7 , by means of which the backrest 5 swings.

The movement of the first control disk 29 is through an adapter part 33 limited, which is rigidly attached to the substructure. Here is a first arm 29 ' by the effect of the Bowden cables 25 and 31 in contact with a first stop surface of the adapter part 33 , which in the representation of 9 limits the movement counterclockwise. Above the first control disk 29 is a second control disc 35 on a side wall 37 the backrest 5 pivoted. A second, upstanding arm 29 '' the first control disc 29 is for an interaction with a lever arm 35 ' second control disk 35 intended. The second control disc 35 has a second lever arm 35 '' on, at which one end of a third Bowden cable 39 is attached, the other end of the handle 41 to take the "Easy Entry Position" (see 3 ) is fixed, which on the outside of the backrest edge of the backrest 5 is arranged (see 4 ). In the position of use are the arm 29 '' the first control disc 29 and the lever arm 35 ' the second control disk 35 clearly spaced from each other. When operating the handle 41 pivots the third Bowden cable 39 the second control disc 35 so far that the arm 29 '' the first control disc 29 and the lever arm 35 ' The second control disc 35 only slightly spaced from each other. When swiveling the backrest 5 reach the arm 29 '' and the lever arm 35 ' in contact with each other and work together. In such interaction, the first control wheel 29 turned (see 10 and 11 ) and in consequence of the rotation of the first control disk 29 the souls of the two Bowden cables 25 . 31 to be pulled. The rotational movement of the control disk 29 clockwise is by a second stop surface of the adapter part 33 limited, as in 11 shown, wherein the bent at its end arm 29 ' the first control disc 29 at the end of the rotational movement in contact with the second stop surface of the adapter part 33 passes, which is opposite to the first stop surface. The adapter part forms here with its second stop surface a stop for the forward movement of the backrest for the "easy-entry position".

With the handle 41 is another, fourth Bowden cable 43 connected, which, however, is used reversed in its operation, ie, the soul is charged to pressure. This fourth, reverse Bowden cable 43 serves to unlock the backrest 5 , being next to the trigger on the handle 41 for the "easy entry position" also a pure unlocking the backrest 5 ie without unlocking the rails 11 . 13 , on one side of the seat 1 arranged operating element, in the present case in the form of a loop 45 (please refer 7 ) is possible, which will be discussed in more detail later.

The shell of the fourth Bowden cable 43 is at a lever 47 mounted, which is pivotable about the pivot axis S of the backrest 5 is and with the fitting 7 interacts so that when the lever 47 pressed down, ie as shown by 8th Turned clockwise, the backrest 5 is unlocked. The soul 43 ' of the fourth Bowden cable 43 is firmly on one arm 49 ' an underlay arranged adapter part 49 appropriate. The lever 47 is also rotationally fixed with a third control disc 51 connected to the opposite side of the side wall 37 is arranged. The embodiment of the third control disk 51 corresponds to that of the control disk 51 on the other side cheek 37 arranged on the outside and in 7 is shown. The third control disc 51 is rotatable about the pivot axis S, wherein it is spaced from the pivot axis S an opening 51 ' in which a lever 53 intervenes. The lever 53 is on a transmission rod 54 fixed, which is rotatable about its own central axis and in a submerged cross tube 55 runs. At the other end of the transmission rod 54 is a corresponding lever 53 arranged, which with the opposite control disc 51 cooperates (see 7 ), so that the movements of the third control discs 51 coupled, ie that at the same time unlocking the backrest 5 done on both sides.

Accordingly, when pulling on the loop 45 - without operation of the handle 41 - only the third control disc 51 turned and the rotary motion over the lever 53 and the transmission rod 54 transferred to the opposite side, so that both fittings 7 be unlocked and the backrest 5 can be pivoted forward without any adjustment of the longitudinal adjustment of the seat 1 ie without unlocking the rails 11 . 13 , or a change in the position of the seat part 3 he follows. This is - in contrast to a release of the release on the handle 41 - the lever arm 35 ' the second control disk 35 out of engagement with the second arm 29 '' the first control disc 29 ie, for example, in the design position of the backrest 5 in the position of 9 ,

Depending on the design of the fittings 7 is also a tilt adjustment of the backrest 5 possible, which by turning the third control disc 51 , for example by means of the loop 45 or a lever, it is then usually several positions of use with different inclination of the backrest 5 adjustable.

All in all This results in an easily operable Vehicle seat, which by means of a single control element, the on the upper edge of the backrest on one side, in particular the outside, is arranged, moved to the "easy-entry position" can be. In this case, other functions of the Seat, such as the longitudinal adjustability or pivoting the back to take a loading floor position, sent for the corresponding position changes to Taking the "Easy Entry Position" used.

Even though not described above, it may be the seat in principle also a bench for Several people act out of being unbalanced, for example 40% to 60%, can be shared. Likewise the use of a Such a seat as a passenger seat possible to easily one possible huge Provide loading area to be able to.
