Definitions

  • Vehicle seat in particular motor vehicle seat
  • the invention relates to a vehicle seat with the features of the preamble of claim 1.
  • the backrest is locked to the C-pillar of the vehicle structure. After releasing the lock, the backrest can be folded forward so that the loading space is enlarged.
  • the invention is based on the object of improving a vehicle seat of the type mentioned. This object is achieved according to the invention by a vehicle seat with the features of claim 1. Advantageous refinements are the subject of the dependent claims.
  • the backrest is articulated to the vehicle structure by means of at least one rocker arm, a pivoting movement of the provided rocker arms at least in phases dictating a forward movement of the backrest, whereby the vehicle seat assumes a front use position, a simple longitudinal adjustment is available which Adjustment options are expanded and thereby the seating comfort is increased without the need for expensive rails, which makes the vehicle seat according to the invention more cost-effective.
  • the backrest can be shifted in one or more phases during which various locks are opened and closed. If the front position is defined as the design position, the pivoting movement of the rocker causes constantly shifting the backrest and thus a transition to a rear use position.
  • the backrest can, for example, be articulated on the vehicle structure at its upper end by means of an (upper) rocker arm. Particularly clear and unambiguous guidance of the backrest is obtained if the backrest is articulated to the vehicle structure by means of a lower link and an upper link or at least two other four-link links to form a four-link link or if, in addition to the linkage, the backrest is linked relative to the vehicle structure using a sliding element is movably guided. Since occupants who prefer a front use position due to shorter thighs generally also have shorter lower legs, it is advantageous if the transition to the front use position is linked to a reduction in the seat height. For this purpose, the backrest preferably lowers slightly when being pushed forward, to which a lowering movement of the seat cushion is preferably coupled.
  • a first lock is provided which releasably locks the rocker with the vehicle structure or with the backrest or releasably locks the backrest with the seat cushion or the vehicle structure, the backrest being pivotable on the seat cushion after unlocking the first lock, whereby the vehicle seat assumes a floor position , or a table position if the seat cushion does not sink.
  • a preferred coupling of the movement of the seat cushion to the movement of the backrest is achieved if the seat cushion is articulated on the one hand by means of at least one front rocker on the vehicle structure and on the other hand on the backrest.
  • This articulation of the seat cushion preferably defines a four-bar linkage or another multi-link bar, which is movable upon transition to the floor position - at the latest after releasing a lock - so that the pivoting backrest can lower the seat cushion downwards by means of this four-bar linkage.
  • the multi-joint can also be used so that the seat cushion when transitioning into the front position of use is pushed forward and optionally also forms the four-bar linkage for articulating the backrest.
  • the vehicle seat can preferably assume a package position in which the seat cushion is folded onto the backrest, so that storage space is made available in front of the vehicle seat.
  • the seat cushion, the backrest rigidly connected to the vehicle structure for this transition, the front rocker and a coupling preferably define a four-bar linkage, by means of which the required movement of the seat cushion is preferably carried out in a defined manner.
  • the coupling can be provided between the front rocker and the seat cushion and can normally be locked to the seat cushion. After unlocking, the front rocker and the coupling can extend relative to one another, whereby the seat cushion folds up with the front end until the top of the seat cushion lies against the backrest when the front rocker and the coupling are in an extended position to one another.
  • the front rocker and the coupling can also assume a different position relative to one another in the package position.
  • the coupling can alternatively be provided between the seat cushion and the backrest, pulling the rear end of the seat cushion along when the seat cushion is folded up until the underside of the seat cushion lies against the backrest.
  • FIG. 2 is a view corresponding to FIG. 1 in the front position of use
  • 3 is a view corresponding to FIG. 1 in the bottom position
  • FIG. 4 is a view corresponding to FIG. 1 in the package position
  • FIG. 5 is a view corresponding to FIG. 1 of the first modification in the design position
  • FIG. 7 is a Fig. 1 and 5 corresponding view of the second modification in the design position
  • FIG. 8 is a view corresponding to FIG. 7 in the front position of use
  • FIG. 10 is a view corresponding to FIG. 9 in the front position of use
  • FIG. 11 is a view corresponding to FIG. 9 in the bottom position
  • FIG. 12 is a view corresponding to FIG. 9 in the package position
  • FIG. 14 is a view corresponding to FIG. 13 in the front position of use
  • FIG. 15 is a view corresponding to FIG. 13 in the bottom position
  • 16 is a view corresponding to FIG. 13 in the package position
  • 17 is a side view of the fourth embodiment in the design position
  • FIG. 18 is a view corresponding to FIG. 17 in an intermediate position
  • Fig. 19 is a view corresponding to Fig. 17 in the front position of use.
  • a vehicle seat 1 has a seat cushion 3 and a backrest 4 for a rear row of seats of a motor vehicle.

  • the backrest 4 is stabilized by the two locks 16 and 18, which in turn stabilizes the seat cushion 3.
  • the vehicle seat 1 can be transferred from the design position into a front use position.
  • the second lock 18 is unlocked so that the lower rocker 12 is movable.
  • the vehicle structure S is preferably designed so that the second lock 18 can lock it again, for example with a further bolt of the vehicle structure S.
  • the vehicle seat 1 can be transferred from the design position into a flat floor position.
  • the first lock 16 is unlocked so that the backrest 4 can pivot forward and downward about the fifth articulation point E.
  • a further four-bar linkage is defined between the articulation points A, B, D and E, by means of which the backrest 4 presses the seat cushion 3 downward.
  • the vehicle seat 1 can be transferred from the design position into a package position.
  • the simple latch lock provided at the second articulation point B is opened, as a result of which the coupling 7 is movable relative to the seat cushion 3.
  • a further four-bar linkage is defined between the articulation points A, B, C and D, which folds up the seat cushion 3 in a defined manner fourth articulation point D allowed.
  • the front rocker 5 and the coupling 7 assume an extended position with respect to one another when the package position is reached.
  • the coupling 7 'pivots upward, taking the rear end of the seat cushion 3 along the backrest 4.
  • the front rocker 5 ensures that the front end of the seat cushion 3 bears against the foot region of the backrest 4, in the present case the region of the lower rocker 12.
