In a method for locking an adjustment device of a motor vehicle seat, a usage situation and/or danger situation is detected. In response to the detected usage situation and/or danger situation, a locking action for the adjustment device is selected, and the selected locking action for the adjustment device is executed.

A vehicle seat arrangement has a vehicle seat for attaching to a vehicle structure of a vehicle, in particular a motor vehicle, with a lower seat part having a seat structure and with a seat back. The lower seat part is mounted or can be mounted in a longitudinally displaceable manner on the vehicle structure by a seat console, wherein at least the seat back is adjustable from a sitting position into a resting or lying position, and wherein between the lower seat part and the vehicle structure an energy absorption device is provided. In the event of a collision of the vehicle with an obstacle, the energy absorption device permits a braked relative movement along a braking path between the vehicle seat, which persists in a forwards movement due to inertia, and the vehicle structure, which is braked due to the collision. In the normal state, the vehicle seat is locked relative to the vehicle structure by a locking device and the locking is released in the event of a collision. The locking device is designed such that the locking is released and the longitudinal displaceability of the vehicle seat is enabled before the mass-induced forces of inertia of the body of a person lying on the vehicle seat are completely supported on the seat structure of the lower seat part, and therefore the body only enters into force-transmitting contact with the seat structure when the vehicle seat is already moving forwards relative to the vehicle structure.

A seating system for at least one occupant in a vehicle interior is disclosed. The seating system may provide a seat assembly with a base assembly configured to be mounted in the vehicle interior and a seat structure configured to be coupled to the base assembly and providing a seat configured for movement relative to the base assembly. Movement of the seat relative to the base assembly may be made by at least two of recline movement or swivel movement or tilt movement. Recline movement may be generally translating movement of the seat structure. Swivel movement may be rotational movement of the seat structure. Tilt movement may be generally translating movement of the seat structure transverse to recline movement. The base assembly may be a mechanism configured to facilitate movement of the seat structure relative to the base assembly.

A long rail assembly is attached to a floor within an automotive vehicle for transposing vehicle seats between a plurality of positions. The long rail assembly includes a rail drive assembly configured to travel along an interior cavity of a fixed long rail. The fixed long rail has a generally U-shaped cross-section and includes a pair of flanges with mating teeth extending inwardly from a pair of outer walls. The rail drive assembly includes a retention latch and a wheel assembly coupled adjacent a first and a second end of the rail drive assembly. The rail drive assembly is operable between a use position and a loaded position in which at least one of the retention latches engages the mating teeth to interlock the rail drive assembly and the fixed long rail in response to forces causing upward loading on the rail drive assembly.

A vehicle seat having a pivoting function about a vertical axis, the seat comprising a pivoting assembly) with a base, a rotating ring mounted on the base by means of a hinge mechanism interposed between the base and the rotating ring, a seating portion frame connected to the rotating ring, directly or via a raising mechanism and/or longitudinal rails, the hinge mechanism allowing rotation, about a vertical main axis, of the rotating ring relative to the base and blocking any substantial movement in the other degrees of freedom, namely the other two rotations and the three translations in an orthogonal reference system.

A vehicle seat having a drive device for driving a adjustment kinematics of the vehicle seat may have an adjustment arm, and a tensioning device. The drive device may have a pinion which can be rotated about a pinion rotation axis and which is in toothed engagement with a tooth segment of the adjustment arm. The tensioning device pretensions the adjustment arm so that the tooth segment is pretensioned in the direction of the pinion. The tensioning device has at least one sliding element which is in abutment with the adjustment arm. During an actuation of the height adjustment kinematics, the at least one sliding element slides along the adjustment arm. The sliding element is resiliently pretensioned by a resilient element.

Adjustable seat device for a vehicle, comprising: -a base portion (10), -a seat portion (20) that is movable with respect to the base portion (10) between a first position, referred to as retracted, and a second position, referred to as extended, -an articulation system (30) forming a deformable parallelogram, which is connected to the base portion (10) and to the seat portion (20) and comprises at least one diagonal support arm (31) connected diagonally to the deformable parallelogram, characterized in that the diagonal support arm (31) is designed to have a first length when the seat portion (20) is in the first position and a second length when the seat portion (20) is in the second position.

A vehicle seat having a seat cushion and a sliding rail, the seat cushion being movable in an elevation direction. The seat includes an anchoring element and a holding device, with the holding device having a cam and a blocking element. The blocking element is mounted so as to be movable at least in rotation between a nominal position and a blocking position so as to prevent the movement of the seat cushion. The cam is mounted so as to be movable between a rest position and an active position in which it drives the blocking element toward its blocking position. The cam is configured to be moved to the active position when a force greater than a predetermined force is applied to the anchoring element.

A track assembly includes a track and a support member connected to and configured move along the track. The support member may include an engagement portion. The engagement portion may be configured to engage the track to limit relative movement between the track and the support member in a loaded state of the track assembly. The engagement portion may be configured not to operatively engage the track or limit movement between the track and the support member in an unloaded state of the track assembly.

A hinge arrangement may be used for a vehicle seat bottom to facilitate pivoting of the seat bottom to open a storage area below the seat bottom. The hinge arrangement may include at least one hinge having two plates connected by a pivot pin and a support structure separate from the at least one hinge. The support structure may be positioned adjacent to the at least one hinge to stop the hinge pin or pins from being ejected in the presence of an impact force.
