Definitions

• Vehicle seat in particular motor vehicle seat
• the invention relates to a vehicle seat, in particular a motor vehicle seat, having the features of the preamble of claim 1.
• a vehicle seat of the aforementioned type is known in which the seat shell is mounted on the front frame by means of a tilt adjuster movable on the seat frame and coupled at the rear by means of an open gate to the seat frame. Regardless of the inclination of the backrest, the seat cushion inclination is adjustable.
• DE 10 2004 057 471 A1 shows a further vehicle seat with a multi-part seat frame.
• An upper, first seat frame carries in the front area the front part of the seat cushion, so there has the function of a seat shell.
• the first seat frame is hinged at the front by means of swinging on an underlying second seat frame and the back of the backrest.
• the second seat frame is articulated by means of further rockers on a base.
• the backrest is attached by means of fittings at the rear end of the second seat frame.
• the rear part of the seat cushion rests on a seat cushion support, which is hinged at the front on the first seat frame and movably guided rearwardly in a gate of the second seat frame, i. is coupled by a slot-pin guide to the second seat frame.
• the invention is based on the object to improve a vehicle seat of the type mentioned. This object is achieved by a driving convincing seat solved with the features of claim 1.
• Advantageous embodiments are the subject of the dependent claims.
• the weight of the occupant can be used for compensation effects on the backrest, preferably to compensate for the weight of the backrest with unlocked fitting, and on the other hand inevitable Matching the movements of the seat and backrest are created, preferably to adapt the seat in its inclination to the inclination of the backrest.
• a “seat” is primarily a trough-shaped component to be understood, which forms a fixed unit together with the seat cushion. In the broader sense, the "seat” but also be a support surface on which the seat cushion rests loose.
• the inventively provided coupling should be a direct coupling, which sets the movements (dynamics) of seat and back in direct connection.
• the aforementioned DE 10 2004 057 471 A1 shows no coupling between its seat cushion support and the back, so that the movement of the backrest only very indirectly and only in the special case of the transition to a bottom position influences the movement of the seat cushion support.
• the coupling according to the invention is designed so that the weight of the occupant exerts a backward pivoting the backrest torque on the same.
• This can replace a compensation spring, as is common, for example, in locking fittings.
• the coupling is preferably designed such that the backrest and the seat shell have coupling elements which cooperate for coupling the seat shell and the backrest and are movable relative to one another along a path, that is to say not only perform a pure pivoting movement relative to one another.
• a first coupling element with a link or cam or other track is preferably provided on a component, ie on the seat pan or on the back, while at the respective other component as a second coupling element, a component is provided which is movable relative to the first coupling element along said path, for example, a sliding block, scanning fingers, pins or a roller. It may then be realized closed slot-pin guides or partially open arrangements. Springs or the like may also be provided which assist the guidance of the second coupling element along the path as an aid, or which themselves define the path as the first coupling means.
• the respective shape, attachment and alignment of the two cooperating coupling elements is preferably selected so that the force-action line of the introduced from the seat weight forces or components in all possible relative positions of the components passes in front of the axis of the backrest.
• the coupling also includes the function of supporting the seat pan on the backrest, i. in the rear region of the seat shell, no further support of the same is preferably provided.
• FIG. 2 is a partial perspective view corresponding to FIG. 1,
• FIG. 3 is a side view, partly in section, of the embodiment in a position of use indicated by a reference line;
• FIG. 4 shows a representation corresponding to FIG. 3 during the transition into a table position
• Fig. 5 is a representation corresponding to FIG. 3 in the lying position.
• a vehicle seat 1 is provided for a motor vehicle. The orientation of the vehicle seat 1 in the motor vehicle and its usual direction of travel define the directions used.
• the vehicle seat 1 comprises a base 3 connected to the vehicle structure of the motor vehicle, for example a pair of seat rails on each of the vehicle seat sides, rockers 5 hinged to the base 3, preferably a rocker 5, a seat frame 7, at the front and rear on both vehicle seat sides hinged to the wings 5 and height adjustable by means of the pivoting rockers 5 relative to the base 3, and a seat shell 9.
• the integrally formed, rigid seat shell 9 carries a not shown in detail in the drawing seat cushion for the occupant, which fixed with suspension rails or the like is connected to the seat 9, so that a structural unit is formed, also referred to as a seat cushion.
• the base 3, the wings 5, the seat frame 7 and the seat shell 9 with seat cushion define the seat part of the vehicle seat 1.
• a backrest 14 is attached by means of fittings 11 on the seat frame 7 and pivotable relative to this about an axis A, whereby the backrest 14 is adjustable in its inclination.
• the fittings 11 are designed as latching fittings (as disclosed, for example, in WO 00/44582 A1, whose respective disclosure content is explicitly included), the axis A is at the same time the relative axis of rotation of the respective two fitting parts.
• the fittings 11 are designed as geared fittings (as disclosed, for example, in DE 199 38 666 A1, the disclosure of which is expressly incorporated herein), the axis A should be defined by the center of the seat-side fitting part.
• the backrest 14 also has a pad on its side facing the occupant.
• the seat shell 9 is movably mounted on the seat frame 7 at its front end in a manner known per se, for example by means of simple joints or by means of a seat cushion inclination adjuster (as disclosed, for example, in US Pat
• the relevant disclosure content of which is explicitly included which, for example, the front edge of the seat shell 9 relative to Seat frame 7 can raise or lower.
• the seat 9 is coupled to the backrest 14, for example suspended or articulated.
• the backrest 14 on both sides of the vehicle seat as a first coupling element on a crank member 16 which is attached or integrally formed as a separate component on the backrest 14 or on the associated fitting 11, that is integrally formed therewith.
• the link member 16 has a link 16a or another track for a second coupling element, which cooperates with the first coupling element, that is, the link member 16 and is movable relative thereto.
• the second coupling element is a roller 17 which is rotatably mounted on an arm 19 of the seat pan 9 about an axis parallel to the axis A, for example by means of a bolt penetrating the roller 17 centrally and secured to the arm 19, and which rolls on the scenery 16a or the train.
• the arm 19 another carrier of the second coupling element or adapter may be provided.
• the said arm 19 projects, for example, from the rear corner of the seat shell 9 upwards and can be firmly connected to or molded onto the same.
• the weight of the seat 9 and possibly the weight of the occupant act.
• the arm 19 is oriented and the chute part 16 is mounted and the link 16a or track shaped, in particular curved, that the force-action line of introduced via the arm 19 weight forces or components in all possible positions of the roller 17 before the axis A passes.
• unlocked fittings 11 then acts on the backrest 4, which tries to swing this forward.
• a backrest compensation spring can thus be dispensed with.
• the attachment of the link member 16 and the shape of the link 16a or web according to the invention also causes the rear end of the seat 9 to be lowered when the backrest 14 is pivoted forward and lifted when the backrest 14 is pivoted back.
• the seat shell can 9 are lowered in addition to a pure coupling to the seat frame 7, for example, if from a position of use, the backrest 14 by Vor- pivoting in a table position with substantially horizontal orientation of the backrest 14 is to be brought, which avoids a cushion pressing here, or if the entire vehicle seat 1 is to be brought by Vorschwenken the backrest 14 and lowering the seat frame 7 by means of the wings 5 in a bottom position, which in the present case allows a deeper bottom position.
• the second possibility can be created by pivoting back of the backrest 14 a lying position with a substantially horizontal orientation of the backrest 14, in which the seat cushion on the seat 9 and the backrest 14 form a continuous lying surface.
