Described herein are illustrative embodiments of a multi-pivot seat base assembly including a first pivot assembly having a fixed part mountable to a floor and a pivotable part, a proximate arm having a proximate end mounted to the pivotable part of the first pivot assembly and a distal end including a fixed part of a second pivot assembly, a distal arm having a proximate end provided with a pivotable part of the second pivot assembly; the proximate end of the distal arm being pivotally mounted to the fixed part of the second pivot assembly; the distal arm including a distal end provided with a seat receiving post; and a controllable damping mechanism provided between the fixed part and the pivotable part of the first pivot assembly.

An override bypass assembly comprises a cable and a pulley wheel operably connected to the cable. The cable in operation rotates the pulley wheel when tension is applied to the cable. The override bypass assembly also comprises a telescoping cylinder assembly operably connected to the pulley wheel. The pulley wheel in operation moves the telescoping cylinder assembly to an unlocked position. The override bypass assembly further comprises a biasing mechanism operably connected to at least one of the pulley wheel and the telescoping cylinder assembly. The biasing mechanism in operation moves the telescoping cylinder to a locked position when tension applied to the cable is relieved.

A rotational brake assembly comprises: a swivel disc having an outer diameter and a plurality of locking holes proximate the outer diameter; a cam having an angled slot; a lifting pin located within the angled slot of the cam; and a rotational brake pin operably connected to the lifting pin. The cam in operation moves to at least one of a locked position and an unlocked position based on an input. The lifting pin in operation moves along the angled slot when the cam moves. The rotational brake pin in operation moves due to motion of the cam. The rotational brake pin in operation moves from an engaged position with the swivel disc to a disengaged position, when the cam moves from the locked to the unlocked position. The rotational brake pin in operation moves to the engaged position, when the cam moves to the locked position.

A seat locking mechanism comprises: a plurality of positional brake mechanisms including a longitudinal brake assembly, a lateral brake assembly, and a rotational brake assembly; and a carriage assembly operably connected to the plurality of positional brake mechanisms. The carriage assembly having a carriage tube and a carriage housing fixedly connected to the carriage tube. The carriage assembly in operation moves each of the plurality of positional brake mechanisms to at least one of a locked position and an unlocked position, when the carriage assembly rotates.

A pumping device is disclosed for a vehicle seat, including a clutch means for receiving rotational force from the outside and transferring power to a link means of a seat cushion. The clutch means includes a clutch block rotated by the rotational force transferred from the outside, a clutch drum which is provided with the clutch block in an inside space and transfers the power to the link means of the seat cushion while rotating by the rotational force transferred from the clutch block, and a plurality of fitting pieces interposed between an outer peripheral surface of the clutch block and an inner peripheral surface of the clutch drum and transferring the rotational force of the clutch block to the clutch drum. The clutch block has a protrusion portion protruding radially from the outer peripheral surface and thus stress concentration is not generated on the plurality of fitting pieces.

An adjustment device includes a housing in which a rotary element is rotatably mounted about a rotational axis, a locking device having a first locking element, connected in a rotationally fixed manner to the rotary element, and a second locking element arranged on the housing and which can be reversibly moved between a primary position in a locked situation, in which the locking elements have a form- and/or force-locking connection, and a secondary position without the connection. An adapter plate is rotates relative to the rotary element and the housing. An unlocking element cooperates with the adapter plate in an actuator region when the second locking element is transferred into the secondary position. The second locking element is shifted by an unlocking height in the unlocking region, and by a lifting height in the actuator region. The actuator region is arranged with the lifting height smaller than the unlocking height.

A lateral brake assembly of a seat locking mechanism comprises: a first lateral brake including a first track bar and a first housing; a second lateral brake including a second track bar and a second housing; a carriage tube operably connected to the first lateral brake and the second lateral brake; a plurality of first slots located in the first track bar; and a first lateral lock pin operably connected to the carriage tube. The first housing in operation moves over the first track bar and locks onto the first track bar. The second housing in operation moves over the second track bar and locks onto the second track bar. The carriage tube in operation moves the first lateral brake and the second lateral brake to at least one of a locked position and an unlocked position, when the carriage tube rotates.

A torque transfer control mechanism that suppresses output-side displacement, and including a rotation control unit that maintains a locked state when an input torque rotating a transfer mechanism is not applied, and releases the locked state when the transfer mechanism rotates. The rotation control unit includes an internal gear and lock plates that include outer teeth that can engage with inner teeth of the internal gear. When an input torque is not applied, the inner teeth of the internal gear engage with the outer teeth of the lock plates, and when the transfer mechanism is rotated, engagement between the inner teeth and the outer teeth is released. Thus, even when torque is applied from the output unit side, engagement between the inner teeth and the outer teeth is not released by the torque.

A structure in which two worm wheels are disposed across a worm provides an increase in locking reliability while maintaining stable operation during rotation. At the time of rotation, respective rotating fulcrums set at both end portions in an axial direction of a worm are supported by bearing parts. At the time of locking, a locking fulcrum set at an eccentric position on one end portion in the axial direction of the worm is supported by one bearing part, while on the other end portion in the axial direction, the rotating fulcrum is supported by the other bearing part as is. As a result, the angle of lead of the worm supported by the pair of bearing parts is changed between the time of rotation and the time of locking and becomes smaller at the time of locking than at the time of rotation, whereby an increase in locking reliability can be achieved.

An adjusting device (1) for a motor vehicle interior component includes a housing (3) in which a rotational element (2) is provided in a rotatable manner about a rotation axis (100). A first locking element (21) is rotationally fixed to the rotational element (2), and a second locking element (22) is provided on the housing (3). The locking elements are reversibly movable relative to each other from a locked situation, in which the locking elements (21, 22) interact with each other in a positively and/or non-positively engaged manner, into an adjustment situation, in which said positive and/or non-positive engagement is released. The adjusting device has an adapter plate (23) which is provided in a rotatable manner relative to the rotational element (2) and the housing (3) and at least temporarily drives a locking element (21, 22).
