摘要:
An adjustment device for a seat depth adjustment of a motor vehicle seat that has (a) a seat pan comprising a seat part and a supporting plate, the supporting plate being slidably connected to the seat part via a guide in a longitudinal direction and (b) an electric gear motor comprising a pinion. The seat part comprises a first gear plate. The supporting plate comprises a second gear plate. The guide has a left and a right profile and a left and a right counterprofile. A toothed rack extending in the same direction is associated with each counterprofile. The teeth of the two toothed racks face each other. Each toothed rack engages a gear wheel. One of the gear wheels engages an idler gear. The other gear wheel and the idler gear engage the pinion of the gear motor.

A step down gear train for an adjusting device of an automotive vehicle seat which has an input shaft and an output shaft that is connected to a pinion. At least one first cogwheel and one second cogwheel are provided in the path between input shaft and output shaft. A follower wheel is provided, in engagement with the first cogwheel, and is not located in the path between the input shaft and the output shaft. A pusher wheel is provided, that is likewise not located in the path between input shaft and output shaft, and is in engagement with both the follower wheel and the second cogwheel, and is carried so as to be longitudinally slidable. An elastic means is provided, that is associated with the pusher wheel, and which elastically biases said pusher wheel into engagement with the follower wheel and the second cogwheel.

The forwardly movable automotive vehicle seat has a seat back and a seat frame with a seat part. The automotive vehicle seat can be moved between a normally adopted utilization position and a forwardly moved position. A locking device is associated with the seat frame; the seat back has a seat back hinge and a stop device. The stop device retains the seat back in the forwardly folded position as long as the seat frame is located in a front portion of a displacement path. The stop device allows the seat back to be released so that it may be folded upward into the normal utilization position when the seat frame is located in a rear portion of the displacement path. The stop device has a first limit stop and a second limit stop, one of said limit stops being disposed on the seat frame and the other one on the seat back.

The automotive vehicle seat has a lengthwise adjustment device, a seat carrier and two rear rockers that are disposed between the seat carrier and the lengthwise adjustment device and that are each connected at an upper hinge point to the seat carrier and at a lower hinge point to the lengthwise adjustment device and a seat belt comprising a belt end on one side and a belt buckle on the other side of the seat. A fastening point, to which a respective one of the belt end and the belt buckle is fastened, is provided on at least one of the rear rockers. The fastening point is located in proximity to the lower hinge point and is nearer to the lower hinge point than to the upper hinge point.

A frame of a motor vehicle seat with a longitudinal guide (20), a seat carrier (26), a front pair of oscillating cranks disposed between the longitudinal guide (20) and the seat carrier (26), and a padding support for a seat padding. A pinion (48) is rotatably disposed on one of the oscillating cranks (22, 23), an actuator (71) being associated with the pinion. A pivot unit (54) is disposed between the two oscillating cranks (22, 23) and is rotationally linked to the two oscillating cranks (22, 23) so as to be pivotal about an axial line. The pivot unit (54) is provided with a sector gear (62) that is centered on the axial line and meshes with the pinion (48), and an adjusting arm (64) is provided which is disposed between the pivot unit (54) and the padding support (30) so that the height of a front edge of the padding support (30) is adjustable by adjusting the sector gear (62).

A power adjustable vehicle seat with a seating that is adjustable in height has a side part and an electromotor. The electromotor comprises a flange-mounted transmission, which transmission is provided with an output shaft and with a transmission case. The side part is provided with a bearing for the output shaft. The transmission case has an area axially facing said bearing for the output shaft. The area facing the side part is open-ended by having no case wall on that open end axially facing the bearing for the output shaft. The side part functions as a case wall of the transmission case once the transmission case is fastened to the side part.

A forward tiltable motor vehicle seat has a seat carrier and a seat back, a hinge mounting is associated with the seat back and comprises an upper hinge arm connected to the seat back and a lower hinge arm hinged about a forward tilt axis to the seat carrier. The seat carrier forms a clamping flank. A cam is provided and is movable between a stop position and a release position. The cam is disposed on the lower hinge arm and rests against the clamping flank in the stop position.

The hinged mounting for a seat back hinge of a motor vehicle seat has a first hinge arm and a second hinge arm; it further has a circular blank that is interposed between said hinge arms. The circular blank has a first circular blank plate that is connected to the first hinge arm, a second circular blank plate that is associated with the second hinge arm, a retaining means for keeping the two circular blank plates together in the axial direction and a releasable stopper device. The second circular blank plate comprises at least one retaining side. The retaining means is rigidly connected to the second circular blank plate. Between the annular region and the second circular blank plate there is formed a circumferential groove in which the first circular blank plate is retained for rotation. The retaining means stiffens the second circular blank plate.
