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.
• the invention is based on the object to further improve a vehicle seat of the type mentioned. This object is achieved by a vehicle seat with the features of claim 1.
• Advantageous embodiments are the subject of the dependent claims.
• the lower fitting part is articulated by means of a hinge on the upper rail, no moments can be transmitted to the upper rail in the event of a crash, but only forces in the seat longitudinal direction or in the vertical, which at most strengthen the bearing forces.
• the joint is arranged above rolling elements and / or a lock which is provided between the lower rail and the upper rail.
• the prevention of torque transmission can be improved by the lower fitting part is articulated by means of a handlebar to the lower rail, so that no moments are transmitted to the lower rail.
• the handlebar provides the necessary length compensation for the relative displacement of the lower rail and the upper rail.
• the vehicle seat preferably has a seat frame, which is articulated at its front end to at least one rocker.
• the rocker is not hinged at its other end to the upper rail, but articulated by means of a vehicle structure fixedly arranged joint on the vehicle structure.
• the rocker can be articulated directly to the vehicle structure by means of this joint, which is fixed to the vehicle structure, for example to a bearing block or foot or the like fixed to the vehicle body structure.
• the rocker may, however, also be indirectly linked to the vehicle structure, for example by the rocker being articulated to an intermediate construction of further gear elements, which in turn is articulated to the vehicle structure.
• the seat frame is preferably articulated at its rear end to the backrest structure.
• a longitudinal adjustment of the vehicle seat move the rear rails provided at the rear end of the vehicle seat relative to the associated, vehicle structure fixed lower rails, while pivots at the front end of the intended swing around the associated, vehicle structure fixedly arranged joints. Overall, this moves the seat frame in the seat longitudinal direction.
• the distance between the vehicle structural joint arranged joint of a rocker and the associated, vehicle structure fixed lower rail remains constant.
• Fig. 1 is a side perspective view of the embodiment with indicated padding in a rear seat longitudinal position
• Fig. 2 is a Fig. 1 corresponding view in a front seat longitudinal position.
• a vehicle seat 1 for example for a rear row of a motor vehicle, is connected to the vehicle structure S of the motor vehicle.
• the arrangement of the vehicle seat 1 within the motor vehicle and its usual direction of travel define the directional information used below.
• the vehicle seat 1 comprises a seat frame 11, which is articulated at its front end on both vehicle seat sides by means of a respective rocker 13 on the vehicle structure S.
• a bearing block or foot or the like is attached to the vehicle structure S for this purpose.
• the defined by the articulation of the rocker arm 13 on the seat frame 11 first joint is denoted by A, which defined by the articulation of the rocker arm 13 on the fauxstrukur second joint with B.
• the second joint B is fixed to the vehicle structure.
• the vehicle seat 1 further comprises a backrest structure 14, which is attached to fitting lower parts 17 on both vehicle seat sides by means of fittings 15.
• the backrest structure 14 by means of the fittings 15 when they are unlocked (in the case of training as locking fittings) or driven (in the case of training as gear fittings), relative to the lower fitting parts 17 about a backrest pivot axis C pivotally.
• the seat frame 11 is, in this case with the ends of its side parts, articulated by means of a respective third hinge D on both sides of the vehicle seat on the backrest structure 14.
• the third joint D is spaced from the backrest pivot axis C.
• the backrest structure 14 and the seat frame 11 are provided in a conventional manner with pads.
• the vehicle seat 1 comprises two seat rails on both vehicle seat sides, in the present case a lower rail 21 fastened to the vehicle structure S (ie fixed to the vehicle structure) and a top rail 22 which is displaceable relative thereto and lockable with the same.
• the lower rail 21 and the upper rail 22 extend in seat longitudinal direction present only over a small area at the rear end of the vehicle seat.
• the lower fitting part 17 is hinged at its rear end by means of a fourth joint E to the upper rail 22, for example approximately centrally and / or above the rolling elements normally provided between lower rail 21 and upper rail 22 and / or above the locking between lower rail 21 and upper rail 22.
• Das Fitting lower part 17 is hinged at its front end by means of a fifth joint F to a handlebar 25, which in turn is articulated by means of a sixth joint G to the lower rail 21.
• the upper rails 22 are unlocked and moved relative to the lower rails 21.
• the fourth joint E, the sixth joint G and the fifth joint F a triangle is defined in each case, which changes its shape during the seat length adjustment, thereby displacing the respective fitting lower part 17 to the front or to the rear. Since the fittings 15 remain locked or are not driven, the backrest structure 14 is also displaced forwards or backwards in the seat longitudinal direction with the fitting bottom parts 17.
• the first joint A, the second joint B, the sixth joint G, the fifth joint F and the third joint D is defined in each case a five-joint, which also changes its shape during seat length adjustment.
• the seat frame 11 is primarily displaced forward or rearward in the longitudinal direction of the seat.
• the swing arms 13 correspondingly pivot about the second joints B.
• the height of the seat frame 11 and the backrest structure 14 above the vehicle structure S and the inclination of the seat frame 11 relative to the vehicle structure S generally change as a result of these movements of the multi-joints These movements are dependent on the ratio of the longitudinal adjustment path to the length of the
• the fittings 15 are unlocked or driven, whereby the backrest structure 14 about the backrest pivot axis C is pivotable.
• the first joint A, the second joint B, the backrest pivot axis C and the third joint D is defined a four-joint, which has its shape during the Backrest tilt adjustment changes.
• the seat frame 11 is displaced slightly forward or backward in the seat longitudinal direction and changed at the same time to a much lesser extent in height and inclination relative to the vehicle structure S at the same time.
• the vehicle seat 1 can also assume a flat non-use position by pivoting the backrest structure 14 forward beyond the region of the backrest tilt adjustment onto the seat frame 11 until it assumes approximately a horizontal position. In the process, during the forward pivoting of the backrest structure 14, the said four-bar joint lowers the seat frame 11 downwards.
