摘要:
The backrest hinge fitting for a vehicle seat comprises a lower fitting part (22) and an upper fitting part (20) pivotably connected together through a hinge axis (24). Pivotably mounted at the upper fitting part (20) are a) a pawl (30) and b) a control lever (38). The pawl (30) comprises a nose (34) and a first interlocking area (36). A second interlocking area (42) and a control ramp (44) are designed onto the lower fitting part (22). The control ramp (44) cooperates with the nose (34) of the pawl (30) and comprises a first depression (46), a curved area (48) and a second depression (50). When the nose (34) resides inside the first depression (46), it is possible for the two interlocking areas (36, 42) to engage. When the nose (34) rests on the curved area (48) or engages in the second depression (50), it is possible for the two interlocking areas (36, 42) to engage. When the nose (34) engages in the second depression (50), the backrest hinge fitting is affixed.

The locking unit of a longitudinal adjustment device of a motor vehicle seat comprises a) a latching strip (22), which has periodically arranged detent openings (24) and detent ridges (26) and is associated with a bottom rail (20) of the longitudinal adjustment device, and b) a catch unit (30), which is associated with a seat rail (28) of the longitudinal adjustment device and comprises at least two catch pins (34), which independently of each can be engaged in detent openings (24) and disengaged together, each catch pin having a front region (42) with a front end (44), a tapering region (46) which adjoins the front end (44) and cooperates with the detent ridges (26), and a shaft region (47) having an upper end, said region adjoining the tapering region (46). The tapering region (46) tapers, as seen looking at a profile view, from an upper point B to a lower point A. The catch pins (34) have a pin axis (40). The tapering region (46) is delimited by a line (60) which connects the points A and B and which does not have a rectilinear progression. As seen looking from the pin axis, the line (60) is not located outside of a straight line (48) connecting points A and B, and is located within the straight line (48) over at least one third of the distance AB.

The base frame of a vehicle seat has two rail pairs (20, 22), two forward rockers (32), two rear rockers (34) and one seat support comprising two side parts (24, 26), one forward traverse (28) and one rear traverse (30). Each rail pair is hinged to a side part by way of a forward rocker (32) and a rear rocker (34). A positional drive (36) is provided for height adjustment of the seat support. A rocker is connected to a cross member (42). A support part (46) is provided which is connected to the cross member (42) and which comprises a hinge area (48) for an adjustment part of the positional drive and a hinge area (50) at the adjacent traverse.

摘要:
The invention relates to a seat base frame for a motor vehicle seat, having pairs of tracks (2, 3) disposed in parallel spaced apart from each other, each having an upper rail (5) longitudinally displaceably guided relative to a lower rail (4) and lockable by means of a locking device (15) on the lower rail (4), a seat structure connected to the upper rails (5), and a transverse support (11) extending substantially perpendicular to the upper rails and connected thereto. In order to provide a seat frame requiring little installation space and having sufficient strength and actuation capability of the locking devices, according to the invention, the transverse support is fixed in the axial direction thereof relative to the upper rails and rotatably connected to same, wherein an actuating lever (10) and a control lever (18) are disposed rotationally fixed relative to each other and spaced apart from each other on the transverse support such that each can be engaged by a locking device for adjusting the locking device between a locked position fixing the upper rail relative to the lower rail and a release position releasing the upper rail relative to the lower rail.

The eccentric joint fitting for a vehicle seat has a first joint arm (20) which a) is fitted with an internally toothed gearwheel (24) and b) forms a first bearing face (26), which are central with respect to a main axis (28), and a second joint arm (20) to which an eccentric wheel (30) is assigned which a) has an externally toothed pinion (32) which is located inside the internally toothed gearwheel (24) and engages therewith, and b) has a second bearing face (34). The pinion (32) and second bearing face (34) are central with respect to an eccentric axis (36). An eccentric drive part (38) is arranged in the region between the first bearing face (26) and second bearing face (34). In a clamped state, the clamping parts (42) displace the eccentric axis (36) with respect to the main axis (28). The eccentric drive part (38) defines the eccentric. A rotary drive of the eccentric drive part (38) causes the pinion (32) to rotate with respect to the internally toothed gearwheel (24) even when the clamping parts (42) are not present, and unless the clamping parts (42) are present equalization of play is not brought about.
摘要:
The invention relates to a predisplacable motor vehicle seat, in particular a front seat of a motor vehicle, comprising only one door per vehicle side. Said seat comprises a back rest (20), a seat part (22) and a back articulated fitting (26) that connects the back rest (20) and the seat part (22). Said fitting comprises a) a backrest arm (28), b) a fitting lower part (30) that is connected to the seat part, c) an adjustment fitting (32) that is arranged between the backrest arm (28) and the seat part arm, and d) a fitting upper part (34) that is connected to the backrest (20) and that can be rotated about an articulated axis (33) of the adjustment fitting (32). A pawl (36) is articulated on the fitting upper part (34) and a catching part (42) is fitted to the backrest arm (28) and normally engages with the pawl (36) and prevents the backrest (20) from tilting forwards. A handle (48) mounted on the back rest (20) allows the forward tilting to be released, said handle (48) being connected to the pawl (36) and disengages from the catching part (42) when the pawl is actuated, such that the backrest (20) can be tilted forwards. A catch hook (56) is articulated on the fitting upper part (34) and a counter hook (58) is provided on the seat part arm. The catch hook (56) and the counter hook (58) only engage when the backrest (20) in the tilted forwards. The counter hook (58) is connected to a memory device (66) of an elongate guide that releases the counter hook (58) when a memorised position of the catch hook (56) is reached and the catch hook (56) is connected to the handle (48) and when the handle (48) is actuated, the catch hook (56) is released from the counter hook (58)
