A drive member including a motor with a longitudinal axis and with at an actuating end a gear mechanism. A support member carries a displacement rod that is movably mounted on the support member. The motor is with its actuating end connected to the support member. The gear mechanism includes a hinge member allowing pivoting of the displacement rod about a pivot axis that is oriented transversely to the longitudinal axis. The gear mechanism engages with the displacement rod and the support member is hingingly attached to a fixation bracket in a hinge connection that is hingeable about an axis which is oriented transversely to the longitudinal axis. The drive member can be used for the adjustment of the backrest of a rear seat in a motor vehicle.

A seat reclining mechanism has a protective device at the shell. The shell has an inner cover and an outer cover with a support plate set therein. The upper part of the shell has a gap for accommodating the rotation of an arm of a rotating plate extends out of the gap. A fence plate cooperates with the arm to keep the gap closed.

A reclinable passenger seat includes a seat pan linear actuator having a rear end pivotally connected to the rear end of the seat pan frame, and a front end pivotally connected to the base by a third fixed pivot. A backrest linear actuator has an upper end pivotally connected to the upper backrest member, and a lower end pivotally connected to the base. A length of the backrest linear actuator is defined between the upper and lower ends. The backrest frame and seat pan frame are configured to move simultaneously between at least a reclined configuration and a berth configuration through pivoting motion about the first and second fixed pivots and about the first and second locations. The length of the backrest linear actuator is substantially the same in the reclined configuration and in the berth configuration.

Proposed is a support driver for a seat and a support assembly including the same. The support driver is configured to operate within a limited space while supporting an occupant comfortably and safely. The support assembly has a structure in which the links push the central portion of the cushion in close contact therewith while remaining in intersection with each other. Advantageously, the links are able to push the cushion with a minimum amount of power within a limited space.

A vehicle seat including a pivot bracket, a back frame, a linear adjustment mechanism, a striker, and a latch. The back frame is pivotally connected to the pivot bracket and configured to pivot about a pivot axis. The back frame includes a first end spaced apart from the and disposed below the pivot axis. The latch is configured to selectively attach the linear adjustment mechanism to the first end of the back frame so that as the first linear adjustment mechanism translates, the back frame pivots from a first use position and a second use position, and selectively detach the linear adjustment mechanism from the first end of the back frame so that the back frame is pivotable to a non-use position.

A seat device that can reliably prevent a rotation operation of a seat by a seated person, in a long state where the back of the seat is along a wall. A rotation lock mechanism (60) that can restrain the rotation of a seat (1), a rotation operation unit (200) that performs a release operation of restraint by the rotation lock mechanism (60), and a rotation operation prevention mechanism (210) that disables the release operation in the rotation operation unit (200), when the seat (1) is in the long state are included. The rotation operation prevention mechanism (210) includes an engaging unit (211) provided in the leg stand (11), and an engaged unit (207) that is provided in the rotation operation unit (200) in the movable stand (20), and disables the release operation in the rotation operation unit (200) by being engaged with the engaging unit (211) when the seat (1) is in the long state.

The invention concerns a seat back (10) for an article of adjustable furniture comprising: a frame (12), at least one movable support section (14, 80) mounted for angular adjustment with respect to the frame; cam means (64) associated with one of the frame and the movable support section, cam follower means (58) associated with the other of the frame and the movable support section; actuator means (38) for moving said cam means or cam follower means associated with the frame with respect to the frame; whereby movement of said actuator means effects relative movement of said cam means with respect to said cam follower means and said relative movement effects angular adjustment of said support section relative to the frame to alter the seat back configuration. The present invention contemplates embodiments where the support section(s) comprise(s) an adjustable head rest (14), an adjustable lumbar support (80) or both.

A seat adjustment first lever is adapted to be mounted to a first lateral end of a recline mechanism of a seatback. Rotation of the first lever about a pivot axis disengages the recline mechanism. The first lever includes a first lever input portion extending from the pivot axis for manual rotation of the first lever. A second lever input portion extends from the pivot axis and is sized to receive an input cable for actuation of the first lever from a remote location. A lever output portion extends from the pivot axis and is sized to receive an output cable to connect the first lever to a second lever on a second lateral end of the recline mechanism.
