A hinge mounting for an adjustment device of a motor vehicle seat having a first external gear wheel comprising a first inner toothed surface and a second external gear wheel comprising a second inner toothed surface. At least two planet wheels mesh with both the first and second inner toothed surfaces. A driving toothed sun wheel meshes with the at least two planet wheels. At least one of the planet wheels has a ring-shaped spring forming the toothed surface of the plane wheel that is radially elastically deformable and permanently exert a force onto the sun wheel, the first inner toothed surface and the second inner toothed surface; and/or the sun wheel comprises a ring-shaped spring forming at least a portion of the toothed surface of the sun wheel and configured to be radially elastically deformable and permanently exert a force onto the planet wheels and bias these with force into abutment with the first and second inner toothed surfaces.

A seat back hinge mounting for a forwardly foldable motor vehicle seat having a first hinge arm and a second hinge arm adapted for relative rotation about a hinge pin. A locking cam is disposed on said second hinge arm and is movable between a locking position and a release position. A first stop flange and a second stop flange are provided on the first hinge arm. The locking cam cooperates with the second stop flange in the locking position and has come free from said second stop flange in the release position. A retainer lug, which is bound by said first stop flange and by said second stop flange in the circumferential direction, is provided on the first hinge arm. A limit stop cooperating with the first stop flange and being spaced the same radial distance apart from the hinge pin as the first stop flange is disposed on the second hinge arm. A retainer device prevents the locking cam from moving from the release position into a region which on the one side is located between the first stop flange and the retainer lug and which on the other side is defined by an arc of a circle about the hinge pin and by the radius of the free end of the retainer lug.

The headrest of an automotive vehicle seat has at least one bar (20) and one supporting member (26). Normally, the supporting member (26) is in a utilization position. When the automotive vehicle is involved in an accident, the supporting member (26) leaves the utilization position and adopts an accident position in which it is located in front of the utilization position. The at least one bar (20) comprises an oblique portion (30) that is located above an upper edge (32) of a backrest of the automotive vehicle seat. Said oblique portion has one component in the x direction and one component in the z direction. The supporting member (26) comprises a guide region (34) that conforms to the oblique portion (30) of bar (20) and that is movable relative to the oblique portion (30). An elastic means (spring 48) biases the supporting member (26) in the accident position. A releasable locking device (52) is associated with the elastic means, which it normally blocks. When the automotive vehicle is involved in an accident, the elastic means is released and causes the supporting member (26) to move from the utilization position to the accident position.

The longitudinal guide for an automotive vehicle seat has two elongate rails, namely one bottom rail and one seat rail, and guide means in the form of roll and/or sliding bodies that are disposed between the rails. Each rail has, when viewed in profile, a) an L-shaped region formed by two L-legs and b) two end regions, each of which joins the L-shaped region and has multiple bends and against which the guide means are resting. The end regions of a rail are mutually interlocked to respectively form an encompassing region with a respective one of the end regions of the other rail. In each encompassing region when viewed in profile, two channels are respectively provided for guide means. Each encompassing region comprises a first channel having first confronting guide surfaces that extend substantially in the y-direction when viewed in the profile of the rails. Said guide surfaces fix the position of a guide means located between them in the z-direction but not in the y-direction.

A hinge mounting for an adjusting device of a motor vehicle seat has a first hinge arm connected to a first internally toothed external gear wheel and a second hinge arm connected to a second internally toothed external gear wheel and at least two planet wheels, each meshing with both the first external gear wheel and the second external gear wheel. A driver pinion meshes with the planet wheels. A carrier is rotatably disposed about a hinge axis and carries the first planet wheel. A compensation device is disposed between the carrier and the first planet wheel and comprises an elastic member that biases the first planet wheel into engagement with the two external gear wheels.
