  • the spring means 31 and the side plate 12 of the seat part 2 are made from one single piece, for example metal or plastic, particularly fiber reinforced plastic.
  • the fitting of the backrest 3 on the seat part 2 can be carried out as follows: Prior to this fitting, the backrest is brought in its easy-entry position and then fixed to the spring element 31 , which is, in this position at least essentially without tension. The backrest is then pivoted, here in the clockwise direction about the pivot axis 28 and the spring element 31 is tensioned at the same time.
  • the toothing 22 which is, in the present case, provided in a resilient manner and is preferably provided integrally with the side part 12 of the seat part 2 , is tensioned here by a movement in the anticlockwise direction and in the process the locking element 9 , which is arranged at the end of the spring element 31 , is pushed over the toothing 22 . Due to the resilient action of the toothing 22 , the latter is always pressed against the locking element 9 , and so noise development is at least reduced.
  • the tensioned spring element 81 which, preferably, is likewise provided integrally with the side part of the seat part, supports the movement of the backrest from its easy-entry position into its use position due to its energy storage during tensioning. In order to adjust the backrest into a new position, the locking element 9 is released, for example by rotating the locking element 9 , this being illustrated in the lower right-hand part of FIG. 4 .
  • FIG. 5 illustrates an alternative embodiment of the vehicle seat according to the invention as per FIG. 4 .
  • the side part 12 of the seat part 2 has a cam 32 which presses the toothing 22 against a locking element 3 .
  • the cam 32 is rotated in the anticlockwise direction, as a result of which the toothing 22 , which is again provided in a resilient manner on the side part of the seat part, likewise moves in the anticlockwise direction and as a result disengages from the locking means 9 , and so the backrest 3 can be adjusted in relation to the seat part 2 .
  • the toothing is tensioned away from the locking means 9 .
  • FIGS. 6 and 7 show a further embodiment of a recliner of the vehicle seat according to the invention.
  • a toothing 16 which is preferably provided integrally with the side part of the seat part 2 .
  • a latching pawl 34 which has on the inside a toothing corresponding to the toothing 16 .
  • the recliner has a locking element 9 which pulls the latching pawl 34 in the direction of the toothing 18 and is arranged in a pivotable manner on the side part of the seat part.
  • latching pawl 34 loads against inside of toothing plate 16 .
  • This makes a constrained loop of the parts 16 , 34 , 9 .
  • This removes all looseness/clearances and makes a structurally sound system.
  • a balanced system of tension and compression with no bending moments is provided.
  • the locking element 9 is driven by a drive means 33 .
  • the recliner is illustrated in its locked state.
  • the latching pawl comprises at its backside 34 . 1 , i.e. opposite from the toothed side a curved surface with a cam 34 . 2 which is preferably provided opposite from the rotation axis of the latching pawl.
  • a contact element 9 is preferably provided opposite from the rotation axis of the latching pawl.
  • this locking element 9 has to be released, as is illustrated in FIG. 7 .
  • the locking element 9 is rotated in the anticlockwise direction in a manner driven by the rotatably provided drive element 33 and in the process runs along the outer contour of the latching pawl 34 , in the process rotating the latter, likewise in the anticlockwise direction, away from the toothing 16 .
  • the contact element touches the opening means 34 .
  • FIG. 8 illustrates yet another embodiment of the vehicle seat according to the invention.
  • This seat again has a seat part and a backrest, which is provided in a pivotable manner on the seat part.
  • a spring element 31 Arranged between the seat part and the backrest is a spring element 31 , in the present case a spiral spring.
  • the centre-point 35 of this spiral spring is not arranged concentrically with the pivot axis 28 of the backrest. This results in particular in space savings.
  • Actuating means actuating cam
