    seating
    The invention relates to a chair with a body between the side walls a seat part is mounted, which is adjustable from a forward displaced to the front edge of the chair basic position in a rearwardly displaced comfort position, wherein at the front end of the seat a swing-footrest is arranged, the articulated arms on the one hand are hinged to the body and the other part at the front end of the seat part, so that the footrest is pivoted in the basic position and swung in the comfort position, wherein at the rear end of the seat part, a backrest is hinged, which pivots from an upright position to a lower flat compared to this comfort position is, wherein the backrest in the basic position of the seat part and in the comfort position of the seat part relative to this is unverschwenkt and retains its basic position and is pivotable in the comfort position of the seat part in the comfort position to the rear, where sch a headrest is provided, which forms an extension of the backrest and is adjustable from a basic position, in which it is approximated to the upper edge of the backrest, in a comfort position in which it is spaced from the upper edge of the backrest.
    Such chairs are known in the art. The fitting construction of such seating makes it possible to adjust the seating in different positions. In the basic position, the footrest of the chair is pivoted and the seat part is displaced towards the front edge of the chair, so that the front end of the seat part closes with the front seat furniture or slightly beyond. The backrest is erected in the basic position, so that it forms approximately an angle of about 90 ° with the seat part.
    Preferably, the seat part is aligned in the basic position so that it is sloping sloping backwards at a shallow angle.
    If the seating furniture from the basic position in one
    Comfort position is adjusted, so first the seat part is moved backwards to the back of the chair, where at the same time by appropriate
    Coupling of the scissor hinges of the footrest
    Swiveling the footrest into the position of use. The backrest retains the previously set basic position. The angle between the backrest and seat part does not change in this case. Together with the seat part, the backrest is shifted slightly to the rear.
    If the backrest is also to be displaced into a comfort position, this can subsequently be pivoted about a fitting which is arranged at the rear end of the seat part. About this fitting, the backrest is connected to the seat part. By appropriate adjustment or weight bearing of the user, the backrest can be adjusted relative to the seat part to the rear in a flat inclined position.
    The position of the footrest does not change and the position of the seat part remains almost unchanged.
    Optionally, the seat part can be slightly raised at its rear end.
    In addition, it is known to provide a headrest which projects beyond the upper end of the backrest. Such a headrest may for example be arranged manually adjustable on the Rückenlehnteil so that it can be adjusted from the basic position in which it is approximated to the upper edge of the back, in a more widely spaced position, so that in the comfort position of the seat part and also in the comfort position of the Rückenlehnteils a longer surface is formed, on which the back or the head of the user can be supported.
    Based on this state of the art, the present invention seeks to provide a chair generic type in which simple means the forced adjustment of the headrest can be realized, but the headrest on the one hand in the adjustment of the seat part from the basic position in the comfort position already is shifted to the comfort position and on the other hand, this comfort position of the headrest is maintained even when pivoting the backrest in the comfort position.
    To solve this problem, the invention proposes that the headrest is indirectly connected via an arranged within the contour of the backrest push rod with the rear end of the seat part, so that in the basic position of the seat part in the basic position and in the comfort position of the seat part in the comfort position is forcibly adjusted.
    This constructive solution ensures that on the one hand the headrest is adjusted when adjusting the seat part from the basic position to the comfort position in the comfort position, so this greater distance from the upper end of the backrest than in the normal position. On the other hand, it is also ensured that in a further movement of the Rückenlehnteils from its basic position in its comfort position, the headrest maintains its comfort position, so is not further shifted. When the backrest part is moved back from the comfort position to the basic position, the headrest remains extended. Only then, when the seat part is moved from its comfort position to the normal position, also inevitably the headrest from the comfort position is returned to the basic position.
    A preferred realization of the invention is seen in the fact that at a side wall of the chair connecting cross member, which is arranged below the rear end of the seat part, a plunger is fixed, which protrudes directed towards the rear of the seat of the Traverse that at the free end of the Plunger one end of a first actuating lever is articulated, the other end is hinged to the lower end of the push rod, and that between these articulation points one end of a second actuating lever is articulated, the other end is hinged to the rear end portion of the seat part, wherein upon adjustment of the seat part the basic position in the comfort position of the first lever is pivoted by the second adjusting lever in a position in which the headrest is pushed out by means of the push rod, and in return movement of the seat part in the normal position by the second lever acting on the first lever back to the normal position zurückbeweg t is.
    The indirect connection of the push rod with the rear end of the seat part takes place on the one hand via the first adjusting lever and on the other hand via the second adjusting lever. When moving the seat part of the
    Starting position in the comfort position of the first lever, which is articulated at the free end of the plunger, erected by the second lever, so that the hinged on the adjusting lever push rod along the backrest longitudinal extension is moved upwards and thus the headrest is extended. Upon further movement of the backrest from the basic position in the comfort position, there is no change in the position of the push rod. To move back the seat part is moved back to the normal position. In this case, the plunger presses on the corresponding end of the first actuating lever, so that it is pivoted, namely to the point of articulation of the second actuating lever on the first adjusting lever. As a result, the push rod moves back down until the headrest has taken its basic position and also the seat part assumes its basic position.
    A preferred development is seen in that the first lever is a triangular shaped part, the tip of the backrest or the back of the chair protrudes, wherein the second lever is articulated at the top and the other two corners of the molded part on the push rod or the plunger are articulated.
    Here, the thrust lever may be a triangular shaped part, for example a triangular flat sheet metal part, wherein the tip of the molded part protrudes to the backrest or the back of the chair. The end of the second control lever is articulated at the top. The other two corners of the molding, which form the hypotenuse of the triangle, are articulated on the push rod on the one hand and on the other hand on the plunger. Due to this arrangement can be alternatively rotated in one or the other direction by actuation of the second actuating lever as a result of the movement of the seat part of the first actuating lever so as to move the push rod in the two possible extreme positions.
    Preferably, it is further provided that the push rod engages through a guide arranged at the upper end of the backrest.
    As a result, a secure positioning of the push rod is achieved in their movement. The guide may be formed for example by a perforated fitting part or a perforated wood part of the backrest.
    It can also be provided that the push rod is straight.
    In a straight configuration of the push rod, the headrest moves substantially parallel to the plane of the Rückenlehnteils.
    Since this is not comfortable for some uses, it is preferably provided that the push rod is formed bent, wherein the center of the arc is at a large distance in front of the back support surface of the backrest.
    This is achieved by the curved design of the push rod, that the headrest in the basic position, although a quasi flush extension of the backrest is in the comfort position but the headrest relative to the support surface of Rückenlehnteils moved forward to the front edge of the chair so that a more comfortable positioning reached for the user's head.
    The movement of the chair in the different positions can be done solely by the weight of the user. But it is also possible to operate the chair by means of a linear actuator or the like, as in the prior
    Technique is known.
    The effects described above also occur.
    An embodiment of the invention is in the
    Drawing shown and described in more detail below.
